Abstract
The invention relates to a tool bit capable of being bent in a combined manner for a winged knife type bending machine. The tool bit comprises a bendable tool body; the bendable tool body is connected with punching equipment, and comprises winged tools; the winged tools are in a right triangular shape; a rotating shaft is arranged on one acute angle of each winged tool; the rotating shafts are hinged on the bendable tool body; the winged tools are respectively arranged at both sides of the bendable tool body; and the two right-angle edges adjacent to the rotating shafts are oppositely arranged on the two winged tools. With the adoption of the technical scheme, the tool bit can be bent in the combined manner in a condition that a lateral edge of a car wall, which obstructs bending, is not cut, so that not only can the technique requirements be met, and the operations of cutting and welding the lateral edge of the car wall, which obstructs bending, can be omitted; and the component integrity can be improved, the mechanical properties and the beautiful appearance of components can be protected, the working efficiency is improved, and the process cost is reduced.
Description
Technical field
The present invention relates to a kind of bender head of making in the tool bending equipment, especially relate to a kind of wing fence formula bender cutter head that can compound bending.
Background technology
In the prior art, as depicted in figs. 1 and 2, bending cutter 1 is to move up and down; Cutter pillow 2 is below bending cutter 1, and cutter pillow 2 is sections of a fluted body, and the 1 downward punching press of bending cutter is placed on the steel plate on the cutter pillow 2; Steel plate is joined under the effect of making a match cutter pillow 2 and bending cutter 1, forms crooked to the inside required bending, in the prior art; On bending machine knife stroke up and down, shelter can not be arranged, that is to say, the width of bending cutter head is less than the steel plate position width of preparing bending; The bending cutter head just can be stamped on the steel plate in this case, like Fig. 3 and shown in Figure 4, when we carry out the compound bending of all directions to workpiece 3; Just in production into when " four Edge Bends ", folding face 4 becomes the shelter on the bending cutter stroke on the workpiece in the workpiece 3, under the prior art situation; Realization to the workpiece in the workpiece 3 before folding face 5 when carrying out bending, in the technical process of this bending in the past, generally be that the flanging that this section is in the way is but removed; As folding face 4 on the workpiece in 3 of working, to get rid of the situation that bending cutter stroke is obstructed, accomplish the bending of back; Like folding face 5 before the workpiece, treat that the postorder bending is rolled well after, on the method through welding will the part welding because of arts demand excision; Though this simple excision this part sedan-chair wall side can solve the situation that bending cutter stroke is obstructed, the overall structure of sedan-chair wall is suffered damage to a certain degree, can reduce the mechanical strength of sedan-chair wall, and has increased the cost of manufacture of excision and welding.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of wing fence formula bender cutter head that can compound bending, through the present technique scheme; Through the bending obstacle time; Wing fence is positioned at contraction state, and the width of bending cutter head is less than the width of obstacle location, gets into punching press wing fence compound bending of completion that launches to match with the cutter pillow during stage; When the bending head returned, wing fence bounced back automatically; Thereby remedied the defective that exists in the prior art.
In order to achieve the above object; Technical scheme of the present invention is achieved in that a kind of wing fence formula bender cutter head that can compound bending, comprises the bending cutter hub, and said bending cutter hub is connected with pressing equipment; Include wing fence; Said wing fence is the right angle trigonometry type, and an acute angle in the said wing fence is provided with rotating shaft, and said rotating shaft is hinged on the bending cutter hub.
The both sides of said bending cutter hub are respectively arranged with wing fence, and two right-angle sides adjacent with rotating shaft are oppositely arranged on said two wing fences.
Be inner concavity on the hypotenuse plane of said two rectangular triangular form wing fences.
The technique effect that the present invention reaches is following: a kind of wing fence formula bender cutter head that can compound bending; By the present technique scheme; Can be under the situation of not excising the workpiece side that hinders bending; Carry out compound bending, not only can satisfy technological requirement, save the obstruction bending excision and the welding job of workpiece side; And strengthened the globality of parts; Protect the mechanical performance of parts and the good looking appearance of parts, improved operating efficiency, reduced the technology cost.

The working state schematic representation that Fig. 6 falls behind down for bending cutter hub among the present invention.
Fig. 7 is the working state schematic representation that the bending cutter hub falls behind down in another embodiment of the present invention.
Among the figure: folding face, the preceding folding face of 5 workpiece, 6 bending cutter hubs, 7 wing fences, 8 rotating shafts, 9 inner concave arc surfaces, 10 indent right angle faces on 1 bending cutter, 2 cuttves pillow, 3 workpiece, 4 workpiece.
The specific embodiment
To combine accompanying drawing that specific embodiment among the present invention is done further explain below.
Like Fig. 5 and shown in Figure 6; The present invention relates to can compound bending wing fence formula bender cutter head, comprise bending cutter hub 6, said bending cutter hub 6 is connected with pressing equipment; Include wing fence 7; Said wing fence 7 is the right angle trigonometry type, and an acute angle in the said wing fence 7 is provided with rotating shaft 8, and said rotating shaft 8 is hinged on the bending cutter hub 6.
The both sides of said bending cutter hub 6 are respectively arranged with wing fence 7, and two are oppositely arranged with rotating shaft 8 adjacent right-angle sides on said two wing fences 7.
As shown in Figure 7, be inner concave arc surface 9 or indent right angle face 10 on the hypotenuse plane of said two rectangular triangular form wing fences 7; Through the setting of inner concave arc surface 9 or indent right angle face 10, can further improve the processed range of work of part in addition among the present invention.
At work, when bending cutter hub 6 carried out pressing and bending downwards, the center of gravity of two wing fences 7 was sagging; Make the width of whole bending cutter have only the width of bending cutter hub 6, break through obstacle after, conflict by on the workpiece 3 of bending in the top of wing fence 7; Wing fence 7 begins to launch and outwards swing; Wing fence 7 launches to be stamped into by on the workpiece 3 of bending, and cooperates with cutter pillow 2, realizes the bending purpose of the preceding folding face 5 of workpiece in the workpiece 3.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
