Abstract
The utility model relates to a kind of stamping die structure with the anti-polishing scratch function of bending, is made up of upper module and lower module; Wherein go up module and comprise upper bolster, described upper bolster is connected with punch retainer by convex mould pad, bending punch to be arranged in punch retainer and to be compressed by briquetting, stripper on punch retainer, also installs roller bearing in one end of described bending punch by spacing pillar, screw, spring fitting; Lower module comprises die shoe, and described die shoe connects die block by die backing plate, also installs push rod in the inside of described die shoe, and described die block has the through hole and for the through pilot hole of push rod of stepping down stretched into for bending punch.The utility model structure is simple, easy for installation, by installing roller bearing in one end of punch, effectively reducing the friction of punch and material strip, making sliding friction change rolling friction into, the surface quality of material strip can be made greatly to improve, reducing the bad order rate of product.
Description
Technical field
The utility model relates to bend punching die, particularly relates to a kind of stamping die structure with the anti-polishing scratch function of bending.
Background technology
At present, domestic market for the precision of stamping products and appearance requirement more and more higher, especially in product bending, existing bending and molding process is generally the fixing structure of die and material strip, in Forging Process, Bending punch contacts with material strip and produces sliding friction, and material strip can be made to produce distortion.When Bending punch moves downward simultaneously, easily leave impression on the surface of material strip, affect the outward appearance of product, time serious, cause waste product, bring economic loss to enterprise.
Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, provides a kind of stamping die structure with the anti-polishing scratch function of bending, the utility model is utilized to effectively reduce friction, substantially increase the surface quality of material strip, reduce the fraction defective of product appearance, improve CSAT.
The technical scheme that the utility model adopts is as follows:
With a stamping die structure for the anti-polishing scratch function of bending, be made up of upper module and lower module;
The concrete structure of described upper module is as follows:
Comprise upper bolster, described upper bolster is connected with punch retainer by convex mould pad, bending punch to be arranged in punch retainer and to be compressed by briquetting, and stripper on punch retainer, also installs roller bearing in one end of described bending punch by spacing pillar, screw, spring fitting;
The concrete structure of described lower module is as follows:
Comprise die shoe, described die shoe connects die block by die backing plate, also installs push rod in the inside of described die shoe, and described die block has the through hole and for the through pilot hole of push rod of stepping down stretched into for bending punch.
The beneficial effects of the utility model are as follows:
The utility model structure is simple, easy for installation, by installing roller bearing in one end of bending punch, effectively reduce the friction of punch and material strip, sliding friction is made to become rolling friction, and the surface quality of material strip is improved greatly, reduce product appearance fraction defective, improve the satisfaction of client, the cost of enterprise drops into also lower simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, upper bolster; 2, convex mould pad; 3, punch retainer; 4, bending punch; 5, stripper; 6, die block; 61, die is stepped down through hole; 62, discharging push rod pilot hole; 7, roller bearing; 8, die shoe; 9, push rod; 10, die backing plate; 11, material strip.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, a kind of stamping die structure with the anti-polishing scratch function of bending, is made up of upper module and lower module;
The concrete structure of upper module is as follows:
Comprise upper bolster 1, upper bolster 1 is connected with punch retainer 3 by convex mould pad 2, bending punch 4 to be arranged in punch retainer 3 and to be compressed by briquetting, and stripper 5 on punch retainer 3, also installs roller bearing 7 in one end of bending punch 4 by spacing pillar, screw, spring fitting.
The concrete structure of lower module is as follows:
Comprise die shoe 8, die shoe 8 connects die block 6 by die backing plate 10, in the inside of die shoe 8, push rod 9 is also installed, die block 6 has the die stretched into for bending punch 4 and to step down through hole 61 and for the through discharging push rod pilot hole 62 of push rod 9.
Specific works process of the present utility model is as follows:
As shown in Figure 1, by pay-off, material strip 11 is sent on die block 6, then module is gone up when moving downward, bending punch 4 also moves downward and drives stripper 5 servo-actuated, stripper 5 contacts with die block 6 and compresses the material strip 11 be positioned on push rod 9 in motion process, notice that stripper 5 should push down material strip 11 prior to bending punch 4, now the end face of bending punch 4 contacts with material strip 11, then bending punch 4 continues descending, material strip 11 is bended, as shown in Figure 1, material strip 11 one end bending after and body in vertical state, now the outer peripheral face of the roller bearing 7 of bending punch 4 its head in descending process contacts with material strip 11, thus change the sliding friction of original structure into rolling friction, decrease frictional force, the material strip 11 that roller bearing 7 roll extrusion simultaneously has been bended, significantly reduce the impression on material strip 11 surface, improve the quality on bending material strip 11 surface, improve CSAT.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to basic structure of the present utility model, the utility model can do any type of amendment.
