Description
Technical field
The utility model relates to needle bearing technical field, especially a kind of novel needle bearing shell edger
Tool.
Background technique
Currently, the drawn cup trimming mode used for needle bearing is mostly to cutting, this is easy to make to the method cut
At the product after trimming, there are differences in height greatly and the disadvantages of oral area burr, and being directed to different products need to be with changing different moulds
Tool, at high cost, low efficiency.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of novel needle bearing shell and cuts
Side mode tool.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of novel needle bearing shell is cut
Side mode tool, including upper die shank, upper mold stamping knife, guiding core, screw and lower die, upper die shank lower end connect upper mold stamping knife, and guiding core is logical
It crosses screw to be threadedly coupled with upper die shank, the underface of guiding core is arranged in lower die, and the upper die shank and the inside for being oriented to core are equipped with
Threaded hole is provided with washer between upper mold stamping knife and screw.
Another embodiment according to the present utility model further comprises being equipped with to float between the upper mold stamping knife and guiding core
Dynamic gap.
Another embodiment according to the present utility model further comprises that the centre of the lower die is equipped with groove.
Another embodiment according to the present utility model further comprises that the lower die side is equipped with rotary notch, slot
Mouth is trapezoidal shape.
Another embodiment according to the present utility model further comprises that cooperation is equipped with the folder that floats in the rotary notch
Block, the floating fixture block other end are connected with spring.
The utility model has the beneficial effects that trimming mode of the utility model using circumference excision bearing outer ring edge,
The disadvantages of big difference in height, oral area burr can effectively be avoided after trimming, and trimming that can be different according to different productions
Mold, it is not necessary to change the structure of entire mold, it is high-efficient, and shaving die production is simple, at low cost, assembly and disassembly is simple, protects
Support easy to maintain.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Die shank on 1. in figure, 2. upper mold stamping knives, 3. guiding cores, 4. screws, 5. lower dies, 6. threaded holes, 7. washers, 8. is recessed
Slot, 9. rotary notches, 10. floating fixture blocks, 11. springs.
Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of novel needle bearing shell shaving die, including it is upper
Die shank 1, upper mold stamping knife 2, guiding core 3, screw 4 and lower die 5, upper 1 lower end of die shank connect upper mold stamping knife 2, and guiding core 3 passes through screw
4 are threadedly coupled with upper die shank 1, and the underface of guiding core 3 is arranged in lower die 5, and upper die shank 1 is internally threaded with guiding core 3
Hole 6 is provided with washer 7, is equipped with flying height, lower die 5 between upper mold stamping knife 2 and guiding core 3 between upper mold stamping knife 2 and screw 4
Centre be equipped with groove 8,5 side of lower die is equipped with rotary notch 9, is trapezoidal shape, rotary notch 9 inside rotary notch 9
Interior cooperation is equipped with floating fixture block 10, and 10 other end of floating fixture block is connected with spring 11.
Working principle of the utility model is: product is moved between guiding core 3 and lower die 5 using feed appliance when work,
Press ram lower end connects upper die shank 1, and when press ram decline, upper die shank 1 drives the guiding core 3 being threadedly coupled with it
Continue to push, product initially enters 5 inner groovy 8 of lower die when being oriented to core 3 completely into product inner hole into product inner hole；When
After product is completely into groove 8, lower die 5 is started to work, and floating fixture block 10 is against the rotation of 5 side of lower die under the action of spring 11
In rotatable notch 9, under downward active force, circumferential fortune is carried out using the rotary notch 9 and floating fixture block 10 of high low setting
Dynamic, when the mold is closed, upper mold stamping knife 2 is screwed with 7 flying height of washer by screw 4, and upper mold stamping knife 2 is fixed, and lower die 5 drives solid
The product rotation being scheduled in groove 8, rotates in a circumferential direction and cuts off extra waste material.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait
Effect, but all will fall within the protection scope of the utility model.
