- Roll forming machines for producing rain gutters are generally well known.
- the gutters are formed from a supply coil of sheet metal which is finished on a first side so that the exterior of the finished gutter has an aesthetically pleasing appearance.

- a cutting station including a shear assembly which may be selectively activated to sever the gutter so that a desired length of finished gutter is separated from the partially finished gutter which remains in the machine.
- Activation of the shear assembly is typically by means of a manually operated lever which drives a cutting blade between a pair of spaced die plates and through the finished gutter. Due to the shape of the gutter being a downwardly concave trough, to achieve a neatly finished cut, it would be desirable to have the blade driven both downwardly and laterally. This requires a split blade, wherein during a phase of the blade movement, the two blade parts are separated to achieve the outwardly lateral cutting action. However, during this phase of the cutting operation, a bent portion of the gutter profile is typically deformed so that the blade is forced to cut through multiple thicknesses of the gutter material. It would therefore be desirable to provide a mechanism whereby the lateral movement of the two blade parts is achieved with maximum mechanical advantage so that a neat cut is achieved without jamming.
- the present invention finds utility in a roll forming machine of the type which forms an indeterminate length panel having a desired lateral profile from a uniform width supply strip of sheet metal having a pair of parallel straight edges.
- the roll forming machine drives the supply strip along a predetermined path of travel through a series of spaced roll forming stations, which gradually deform the initially flat strip into the desired lateral profile, illustratively a downwardly concave trough, to form a rain gutter.
- the shear assembly includes a pair of coplanar blade members separated along a generally vertical line.
- the blade members are pivotally connected at their upper ends to a vertically movable actuator block by respective link members which are pivotally connected to the block and to the two blade members.

- the guide surface bevels reach the guide rollers.
- the cam followers prevent further downward movement of the blade members, so continued downward movement of the actuator block causes the upper ends of the blade members to pivot outwardly about the cam followers, in the opposite angular direction from the previous outward pivoting.

Abstract
Description
- This invention relates to a roll forming machine for producing a rain gutter and, more particularly, to a shear assembly disposed in a cutting station at the exit end of the roll forming machine.
- Roll forming machines for producing rain gutters are generally well known. In such a machine, the gutters are formed from a supply coil of sheet metal which is finished on a first side so that the exterior of the finished gutter has an aesthetically pleasing appearance. As the sheet metal is driven through the machine along a predetermined path of travel, its lateral profile is gradually transformed from a flat sheet into a downwardly concave trough having a desired lateral profile and with the finished side of the sheet metal forming the exterior surface of the trough. As the finished gutter exits the machine, it passes through a cutting station including a shear assembly which may be selectively activated to sever the gutter so that a desired length of finished gutter is separated from the partially finished gutter which remains in the machine. Activation of the shear assembly is typically by means of a manually operated lever which drives a cutting blade between a pair of spaced die plates and through the finished gutter. Due to the shape of the gutter being a downwardly concave trough, to achieve a neatly finished cut, it would be desirable to have the blade driven both downwardly and laterally. This requires a split blade, wherein during a phase of the blade movement, the two blade parts are separated to achieve the outwardly lateral cutting action. However, during this phase of the cutting operation, a bent portion of the gutter profile is typically deformed so that the blade is forced to cut through multiple thicknesses of the gutter material. It would therefore be desirable to provide a mechanism whereby the lateral movement of the two blade parts is achieved with maximum mechanical advantage so that a neat cut is achieved without jamming.
- The present invention finds utility in a roll forming machine of the type which forms an indeterminate length panel having a desired lateral profile from a uniform width supply strip of sheet metal having a pair of parallel straight edges. The roll forming machine drives the supply strip along a predetermined path of travel through a series of spaced roll forming stations, which gradually deform the initially flat strip into the desired lateral profile, illustratively a downwardly concave trough, to form a rain gutter. As the gutter leaves the machine, it passes through a cutting station, which includes the inventive shear assembly. According to this invention, the shear assembly includes a pair of coplanar blade members separated along a generally vertical line. The blade members are pivotally connected at their upper ends to a vertically movable actuator block by respective link members which are pivotally connected to the block and to the two blade members. Near the lower ends of the blade members are dogleg shaped cam openings which cooperate with respective cam followers secured to the machine. Guide rollers secured to the machine are disposed on opposite sides of the blade members, which have guide surfaces parallel to the vertical movement of the actuator block. The guide surfaces are terminated at their upper ends with beveled surfaces which are angled toward each other. Thus, the movement of the blade members starts off vertically downward until the dogleg bends of the cam openings reach the cam followers. At this point, the lower ends of the blade members pivot outwardly about the guide rollers as they continue to move downwardly. When the ends of the cam openings reach the cam followers, the guide surface bevels reach the guide rollers. The cam followers prevent further downward movement of the blade members, so continued downward movement of the actuator block causes the upper ends of the blade members to pivot outwardly about the cam followers, in the opposite angular direction from the previous outward pivoting. The link members provide enhanced mechanical advantage to movement of the blade members during this final pivoting phase.
- The foregoing will be more readily apparent upon reading the following description in conjunction with the drawings in which like elements in different figures are identified by the same reference numeral and wherein:
-
FIG. 1 shows an exemplary rain gutter lateral profile which can be produced by a roll forming machine incorporating the present invention; -
FIG. 2 is a perspective view of an exemplary roll forming machine in which structure constructed according to the present invention is incorporated; -
FIG. 3 is a perspective view showing the inventive shear assembly, with covers removed, at the exit of the roll forming machine; -
FIG. 4 is a top plan view of the inventive shear assembly; -
FIG. 5 is a perspective view showing the rear of the inventive shear assembly and illustrating the activation mechanism; and -
FIGS. 6-8 are front elevation views of the inventive shear assembly, with covers removed, showing different stages of the cutting operation. - Referring to the drawings,
FIG. 1 shows the profile of an exemplary rain gutter, designated generally by thereference numeral 10, which can be produced by a roll forming machine incorporating structure embodying the present invention. Thegutter 10 is generally in the form of a downwardly concave trough having aback wall 12, alower wall 14 and aface wall 16. As is the general practice in the art, theback wall 12 is designed to abut supporting structure on a building to which thegutter 10 is attached, and therefore cannot be seen by an observer. However, theface wall 16 is designed to be visible from outside the building and therefore it is desired that the exterior surface of theface wall 16 be finished to provide an aesthetically pleasing appearance. To provide strength to thegutter 10, theupper end 18 of theface wall 16 is bent and folded, as shown in the drawing. -
FIG. 2 shows a roll forming machine, designated generally by thereference numeral 20, which may be used for forming thegutter 10. As is conventional, themachine 20 has a spindle (not shown) near itsentry end 22 for supporting a supply coil of sheet metal (not shown). The sheet metal supply coil is of uniform width and has a pair of parallel straight edges. The sheet metal is finished, as by painting for example, on one side so that the exterior surface of the formedgutter 10 is finished. As is known in the roll forming art, the supply coil is pulled by driven rollers so as to travel through themachine 20 along a predetermined path past a plurality of spaced roll forming stations. As the supply coil is pulled through themachine 20, each successive roll forming station operates to gradually transform the lateral profile of the sheet metal from a flat sheet to the profile shown inFIG. 1 . Thus, the sheet metal starts as a flat sheet with its finished side on the bottom and gradually assumes a downwardly concave trough-like shape with its finished side on the outside of the gutter. At theexit end 24 of themachine 20 is acutting station 26 for cutting the formed gutter to a desired length. Thecutting station 26 includes a pair of spacedparallel die plates 28. Each of thedie plates 28 has arespective opening 30 aligned with the opening of the other die plate through which the finished gutter passes as it exits themachine 20. Theopenings 30 have generally the same shape as the profile of the finished gutter, but are larger so that the finished gutter passes freely therethrough. The foregoing is well known in the art of roll forming machines and does not form a part of the present invention. - As is clearly shown in
FIGS. 3-8 , the inventive shear assembly which forms a part of thecutting station 26 includes a blade assembly having a pair ofcoplanar blade members blade members plates 28. Each of theblade members cam openings straight portion straight portion 44,46 at the upper end of the first straight portion which is angled toward the other blade member. A pair ofcam followers machine 20 and extend each into a respective one of thecam openings - Each of the
blade members side edge portion side edge portions side edge portion blade members guide rollers machine 20, with each being in contact with the guide surface of a respective one of theblade members - The
blade members block 64 near their upper ends, above therespective cam openings rigid links links block 64 and to a respective one of theblade members block 64 is generally rectilinear in shape and has rack gear teeth 70 (FIG. 5 ) on its side surface facing into themachine 20. To selectively move theblade members machine 20, there is provided an actuator coupled to theblock 64. The actuator includes arotary gear 72 engaged with therack gear teeth 70 of theblock 64. Theshaft 74 is journaled for rotation on themachine 20 and therotary gear 72 is mounted to theshaft 74 for rotation therewith. To rotate theshaft 74, there is provided alever arm 76 which is secured to theshaft 74 and extends transversely thereto, preferably orthogonally. - In operation, when it is desired to sever a length of rain gutter, the
machine 20 is stopped and the operator takes hold of thelever arm 76. As thelever arm 76 is pulled upwardly, the resulting rotation of therotary gear 72 causes theblock 64 to move downwardly. As theblock 64 moves downwardly, thelinks blade members cam followers straight portions cam openings guide rollers side edge portions blade members blade members lower wall 14 of thegutter 10. Continued upward movement of thelever arm 76 results in thecam followers straight portions 44,46 of thecam openings guide rollers side edge portions blade members guide rollers FIG. 7 , causing theblade members back wall 12 and theface wall 16 of thegutter 10. - When the
cam followers straight portions 44,46, further downward movement of theblade members cam openings side edge portions cam followers guide rollers FIG. 7 .) Accordingly, further upward movement of thelever arm 76 causes downward movement of theblock 64 and outward pivoting of thelinks blade members cam followers FIG. 8 . Thelinks blade members blade members blade members back wall 12 and theface wall 16 of thegutter 10. This enhanced mechanical advantage is advantageous because while cutting through theupper end 18 of theface wall 16, theblade member 32 folds theupper end 18 and therefore has to cut through a triple thickness of gutter material before the cut is completed. By providing the enhanced mechanical advantage at this point, the inventive shear assembly allows the operator to cut through the entire gutter with one smooth stroke. - In addition to the disclosed shear assembly construction possessing the benefit of enhanced mechanical advantage, it is also more vertically compact, with a much shorter vertical stroke, as compared to a conventional single blade guillotine shear assembly. This results in a lighter weight shear assembly which is easily handled by a single mechanic when it is required to remove the shear assembly from the roll forming machine for general maintenance or trouble shooting.
- Accordingly, there has been disclosed an improved shear assembly for a rain gutter roll forming machine. While an illustrative embodiment of the inventive shear assembly has been disclosed herein, it will be appreciated by those of skill in the art that various modifications and adaptations to the disclosed embodiment are possible. It is therefore intended that this invention be limited only by the scope of the appended claims.
