Description

Novel cold forging burr-free stamping die

Technical Field

The utility model relates to a stamping die field, concretely relates to cold forging stamping die.

Background

The factors of burr generation in the stamping process of stamping parts are many, for example, the assembly of a burr stamping die is improper due to too large and too small blanking gaps or uneven gaps, the gap of a die guide part is too large, the assembly of a concave-convex die is asymmetric, the precision of a press is poor, the gap of a guide rail of the press is too large, the parallelism between the bottom surface of a die and a worktable of the press is not closed, the verticality between the stroke of a die slide block and the worktable of the press is not uniform, the rigidity of the worktable of the press is poor, deflection is generated in the stamping process, the gap change between the die and the press is caused, the curvature of a stamping material is too large, the material is uneven during feeding of the stamping material, the stress is not uniform, the burr generation in the production process can be caused by the abrasion of a die edge or the bite of a knife, the hardness of the stone of the concave-convex, the existing industry generally processes the generated burrs again by using filing, electrolysis, polishing, grinding and other methods, so that the production cost is greatly increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: the utility model provides a novel cold forging does not have burr stamping die, includes die body (12) and lower die body (13), its characterized in that: the die is characterized in that an upper die base (1) is arranged on the upper portion of an upper die body (12), an upper base plate (2) is arranged on the lower portion of the upper die base (1), a plurality of guide pillars (5) are vertically arranged on the upper base plate (2), the guide pillars (5) penetrate through an upper clamping plate (3) arranged on the lower portion of the upper base plate (2), an upper punch (11) is arranged in a hollow area in the middle of the upper base plate (2), an upper supporting plate (4) is arranged on the lower portion of the upper clamping plate (3), a lower die plate (6) is arranged on the upper portion of a lower die body (13), a lower base plate (8) is arranged on the lower portion of the lower die plate (6), a lower knife edge (7) is arranged in the hollow area in the middle of the lower base plate (8), a lower die base (9) is arranged on the lower portion of the.

Furthermore, the number of the guide posts (5) is not less than 4.

Furthermore, a guide hole is formed in the position, corresponding to the guide post (5), of the lower template.

Furthermore, the upper punch (11) is of a trapezoidal structure, and the lower knife edge (7) corresponding to the upper punch (11) is of a hollow trapezoidal structure with the same size.

The beneficial effects of the utility model are that, compare with prior art, because the utility model discloses changed the shape of traditional edge of a knife inner wall, made the product be in when the drift part is used with the edge of a knife is laminated completely, spills out the burr, reaches the purpose of deburring.

Additional aspects and advantages of embodiments of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
