Loaded on the installation lid 42 in fixing seat 41.The side of installation lid 42, which is run through, to be had for helping weld tabs rim charge (to help weld tabs material strip by punching
Remaining rim charge afterwards) discharge hole 421 that passes through, the upper surface of cavity plate 22 is fixedly connected with feed block 7, and the side wall of feed block 7 passes through
It is installed with the feed opening 71 opposite with 421 position of discharge hole, which is feeding for helping weld tabs material strip to penetrate to improve material strip
Stability in the process.
As shown in Figure 1 and Figure 4, the two sides of fixing seat 41 are provided with sliding panel 43, and two pieces of sliding panels 43 are far from fixing seat
41 one end is mutually permanently connected by fixed plate 44.Two springs 45, and bottom are provided between fixed plate 44 and fixing seat 41
The side wall of seat 21 is fixedly connected with the block 46 mutually pushed against with fixed plate 44, fixed plate 44 and fixing seat 41 it is opposite side it is equal
Mounting groove 8 there are two opening up, the both ends of two springs 45 are respectively positioned in fixed plate 44 and fixing seat 41 in corresponding mounting groove 8.
The opposite lateral wall of the two of two pieces of sliding panels 43 is fixedly connected to interlocking bar 47, and the fixation of two interlocking bar 47 is arranged
There is linkage bearing 48, guiding surface when upper mold 1 pushes on drive rod 3 can push linkage bearing 48, so that two pieces of sliding panels
43 is mobile towards 22 direction of cavity plate.
The upper surface of fixing seat 41 opens up the groove 9 of perforation 41 two sides of fixing seat, passes through between two opposed inner walls of groove 9
Interference fit is fixedly installed with positioning bearing 49, and two positioning bearings 49 are arranged coaxially and fixation is equipped with shaft 410 simultaneously,
The both ends of shaft 410 protrude from the two sides of fixing seat 41.The equal fixing sleeve in the both ends of shaft 410 is equipped with installation bearing 411, installation axle
The outer ring for holding 411 is fixedly connected with ring gear 412, and two installation bearings 411 are unilateral bearing.
Two pieces of sliding panels 43 are integrally formed item 413 with teeth towards the side of cavity plate 22, two toothed racks 413 respectively with two
Ring gear 412 is intermeshed, and then the generation of shaft 410 is driven to correspondingly rotate.
As shown in Figure 3 and Figure 4, the lower end surface for installing lid 42 offers the mounting hole 422 being connected with discharge hole 421, pacifies
It fills and is rotatably connected to upper bearing (metal) 414 between two opposed inner walls in hole 422, fixing sleeve, which is equipped with, in shaft 410 is located at two locating shafts
Lower bearing 415 between holding 49, the upper end of lower bearing 415 protrude from fixing seat 41 and are located in mounting hole 422,414 He of upper bearing (metal)
Lower bearing 415 is disposed as unilateral bearing and locking direction on the contrary, upper bearing (metal) 414 and lower bearing 415 are pushed against respectively in helping weld tabs
The upper and lower two sides of rim charge.
The concrete operations process of the present embodiment is as follows:
When lower die 2 pushes, the bearing 48 that will link of the guiding surface on drive rod 3 is inwardly pushed so that rack gear 413 to
Interior sliding simultaneously drives ring gear 412 to rotate forward, and the installation bearing 411 and lower bearing 415 that rotate forward are lock state, install bearing
The rotation of ring gear 412 is passed to shaft 410 and lower bearing 415 by 411, so that the synchronization of lower bearing 415 rotates forward, and on
Bearing 414 is all lock state in forward rotation direction, and by the squeezing action of upper bearing (metal) 414 and lower bearing 415, upper bearing (metal) 414 is just
Turn to push and the movement of weld tabs rim charge, lower bearing 415 is helped to pass through reversion cooperation discharging.
The reset of lower die 2 makes, and retracts in the elastic reaction bottom plate 44 of spring 45 with two rack gears 413, and makes tooth
Ring 412 is flipped, and installing bearing 411 at this time is rotary state, so that the in situ rotation of ring gear 412 turns without influencing
The rotation of axis 410.
Even if the rotation of ring gear 412 produces certain influence to shaft 410, lower bearing 415 is also rotary state at this moment,
By the frictional force between material strip it is also possible that lower bearing 415 and shaft 410 relatively rotate without will affect material strip
Displacement.
Furthermore even lower bearing 415 receives lower amplitude influences, but upper bearing (metal) 414 is lock state in forward rotation direction,
It can effectively prevent that weld tabs rim charge is helped to retract, so that lower bearing 415 be avoided to occur accordingly to rotate.Finally to help weld tabs material
Band can be fed by stablizing.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.
