Description
Technical field
The utility model belongs to technical field of mold, more particularly to a kind of U-shape lock button bend punching die anti-attrition roller bearing
Device.
Background technology
The core rod of current U-shape lock button bend punching die is essentially integral structure, and bending part rounding is processed, so
And, there is following point in punch forming in this kind of design：
Firstly, because the friction needed at rounding angle between core rod and product is sliding friction, frictional force is larger, core rod
The rate of wear is very fast, need to often change left and right core rod；
Secondly, what core rod was contacted with product needs because frictional force is big at rounding angle, and the abrasion to product is also larger, often draws
Wound lock, and, frictional force is big at the fillet that core rod is contacted with product, causes bending spacing and the depth of parallelism after lock bending and molding
Difference.
Finally, after core rod abrasion, whole mould of dismantling need to be shut down, replacing construction is long, time and effort consuming.
Utility model content
For the problem that prior art is present, the utility model provides a kind of U-shape lock button bend punching die and is rolled with anti-attrition
Shaft device, can be one time punching molded to U-shape lock button, and speed is fast, efficiency high.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of U-shape lock button bend punching die anti-attrition roller assembly, including left mould core, the axle that rolls left, right mould core, right roller bearing
With lower mould floating block；Circular hole is equipped with the left mould core and right mould core；The axle that rolls left is arranged in the circular hole on left mould core and can be with
Rotated in circular hole, right roller bearing is arranged in the circular hole on right mould core and can be rotated in circular hole；Lower mould floating block is arranged on a left side
Between core rod and right mould core.
Further, the radius of the circular hole is equal with the radius of corner for needing to lead.
Further, left guide ledges are provided with the left mould core.
Further, right guide ledges are provided with the right mould core.
Further, the length of the axle that rolls left is equal with left mould core width, the length of right roller bearing and the width of right mould core
It is equal.
Further, to roll left and scribble lubricating oil between axle and right roller bearing and each self-corresponding circular hole.
The beneficial effects of the utility model are：The utility model employs original integral type core rod is contacted with product
Circular hole is opened at fillet, and roller bearing is set in circular hole, the sliding friction between core rod and lock is changed to rolling friction, so as to subtract
The abrasion of few core rod, reduces pull probability of the core rod to lock, and the only roller bearing of replacing core rod, and low cost, replacing speed are fast.

Specific embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model
Define.
Referring to figs. 1 to shown in Fig. 4, a kind of U-shape lock button bend punching die anti-attrition roller assembly of the utility model, mainly
Including：Left mould core 2, the axle 3 that rolls left, right mould core 6, right roller bearing 5 and lower mould floating block 4；Set at the upper fillet of left mould core 2 and right mould core 6
It is equipped with and radius of corner identical circular hole 6-2；Roll left axle 3, right roller bearing 5 respectively with left mould core 2, right mould core 6 on circular hole 6-2 roll
It is dynamic to coordinate, it is coated with lubricating oil and each self-corresponding circular hole 6-2 between respectively in the axle 3 that rolls left, right roller bearing 5；And the length of the axle 3 that rolls left
Degree length equal with the width of left mould core 2, right roller bearing 5 is equal with the width of right mould core 6, lower mould floating block 4 be arranged on left mould core 2,
Between right mould core 6.The both sides of left mould core 2 are provided with left guide ledges 2-2, and the both sides of right mould core 6 are provided with right pilot platform 6-1.
When use, left mould core 2, right mould core 6 and lower mould floating block 4 are assembled into an entirety, then left guiding is convex
Platform 2-2 is aligned with right guide ledges 6-1 with the groove of the die cavity both sides being arranged in lower template 7, then whole device nesting is filled
Fit in the die cavity in lower template 7, left guide ledges 2-2 and right guide ledges 6-1 is slided with each self-corresponding groove match somebody with somebody respectively
Close, the position that U-shape lock button 1 is placed in the lower template 7 be respectively arranged with left and right under mould enter son 9, afterwards lower mould enter son 8 and front lower mould
Enter son 10, to play position-limiting action, by the axle 3 that rolls left with right roller bearing 5 to the punching press rounding angle of U-shape lock button 1, due to being to roll to rub
Wipe, it is smaller relative to force of sliding friction, so be not easy that U-shape lock button 1 is caused to pull damage, and as a result of roller bearing
Design, roller bearing can be easily changed after roller bearing 3 and the frequent punching press of the workpiece of U-shape lock button 1 cause to damage, it is not necessary to as
Left mould core 2 and right mould core 6 are originally equally changed, the production cost of lock is significantly reduced and is saved shutdown and change whole mould
Time.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
