Abstract
The utility model discloses a quickly rotating feed mechanism employing arbitrary equipartition function of an overrun clutch. In press working of metals, a rotary table is used for automatically feeding semi-finished products, and the feed mechanism is a component for stamping automation. For some deep sleeve drawing pieces, when a main body is formed, parts still need to be processed in drawing for many times. On a normal press machine, a slide block returns to an upper dead point, the distance between the top of a work piece and the ground only few millimeters, the feeding process is limited in the time during a crank shaft of the press machine rotates 20 degrees, some feed mechanisms cannot finish the work. The quickly rotating feed mechanism can feed materials in place within the limited time. Otherwise, a large-scale or special press machine is needed. The technical scheme of the utility model is as follows: the slide block is in reciprocating straight-line motion, and passes through a pull rod, a corresponding lever enlarging mechanism and the overrun clutch, so as to change from small distance straight-line motion into circular arc swinging, thus, the overrun clutch performs quick circular intermittent feeding action under a condition of arbitrary equipartition.
Description
One, technical field
The utility model is in stress metal processing, uses rotating disk and does the semi-finished product self-feeding, and promptly the secondary punching automation is a part of punching automation.
Two, background technology
Existing rotating disk feeding, type of belt drive has multiple, and common has: at the press crankshaft end, by the dress eccentric disc, cam disc or utilization frictional drive, wedge, ratchet, sheave etc.But, aborning, the stamping parts of some dark barrel shape being arranged, main part is extended after the moulding, and certain position on the main body still needs multi-step forming processes to accomplish.For example, series automobiles fuel filter shell, after the main body moulding, extend and on ordinary press, carry out in the part, and slide block is got back to top dead centre, and the stamping parts highest point has only several millimeters apart from the patrix bottom surface; This kind situation is used other feed mechanisms and the current rotating disk feeding that has, and has not had possibility.Have only mould equipment on large-scale high-stroke forcing press or special pressure machine.
The utility model can overcome this problem, on ordinary press, and the automatic press feeding.
Three, summary of the invention
The utility model is proof from practice, in the time of 20 ° of press crankshaft corners, accomplishes feeding.Solve its technical problem, the technical scheme of being taked is: use any five equilibrium and the function of intermittent movement of freewheel clutch in the rotating disk feeding; Use corresponding leverage any small distance rectilinear motion that can realize, be transformed into arc swing.The rocking bar of corresponding lever swing arm and freewheel clutch can be regulated length, and the swing arm seat can the shift position.At first, according to the station number of the operation number of part processing design rotating disk, station number=process number+2.
Such as, part needs seven procedure punching presses, nine stations of feed rotary table design; Per 40 ° are rotated a station, and the feeding driving force is installed pull bar from press ram at cope match-plate pattern; Pull bar is done linear reciprocating motion, and the pull bar bearing pin drives corresponding lever swing arm around 40 ° of spot wobbles, and swing arm connects the rocking bar on the freewheel clutch; Make it to do 40 ° of arc swings around axle, the clutch axle is rotated 40 °; The engagement of axle other end conical gear makes the rotating disk vertical shaft rotate 40 °; Feed rotary table is pressed circumference nine stations (360 °/40 °), and feeding is accomplished in intermittently rotation.Adorn a clutch-plate on the axle, promptly the elastic opening pad is adjusted the rotating disk part, and it is lifted down, and the conical gear on the link mandrel does not just mesh.
Wherein 1, the size of patrix bottom surface to workpiece peak, be the effective working size of pull bar.
2, confirm the station number after, corresponding lever swing angle=360 °/station number.
3, calculate lever length arm size by the swing number of degrees, confirm rocking bar length.
Four, description of drawings
Below in conjunction with accompanying drawing, the utility model is further specified:
Fig. 1 is an installation diagram
Fig. 2 is that installation diagram is overlooked
Fig. 3 is that installation diagram C is to (three figure part sequence numbers are consistent)
Among the figure 1, cope match-plate pattern 2, convex mould base 4, backstay 5, rotating disk 7, the punch 9 of extending, the die 12 of extending, ejector beam 18, rotating disk vertical shaft 20,21, conical gear 24,25 inside and outside bent plates 28, pull bar 29, swing arm 30, freewheel clutch 34, clutch-plate 44, stripper 49, axle 54, bearing pin 55, swing arm seat 56, rocking bar
Five, the specific embodiment
The slide block backhaul, pull bar 28 rises with slide block, when pull bar 28 is run into bearing pin 54; Drive swing arm 29 angle of spot wobble around swing arm seat 55, the rocking bar 56 that swing arm 29 connects on the freewheel clutch 30 makes it to do corresponding number of degrees arc swing; Freewheel clutch axle 49 is then rotated the identical number of degrees; 19,21 engagements of axle other end conical gear make rotating disk vertical shaft 18 rotate the corresponding number of degrees, and feed rotary table 5 is pressed the intermittently swivel feeding of circumference station number.
Indicate: the word segment that original text increases, draw a solid line below.
Claims (2)
1. any five equilibrium fast rotational of freewheel clutch feed mechanism; Comprise that total necessity such as rotating disk in the existing dial feed structure, stopper, location possess part; It is characterized in that: use freewheel clutch function of five equilibrium and intermittent movement arbitrarily in the rotating disk feeding; Use corresponding leverage,, be transformed into arc swing any small distance rectilinear motion that can realize.
2. feed mechanism according to claim 1 is characterized in that: the rocking bar of corresponding lever swing arm and freewheel clutch can be regulated length, and the swing arm seat can the shift position.
