Abstract

The invention discloses a bent PIN riveting die. The riveting die comprises an upper die (2) and a lower die (4), wherein the upper die (2) sequentially comprises an upper die base (21), an upper backing plate (22), an upper clamping plate (23), a stoppet plate (24) and a stripper plate (25); the lower die (4) sequentially comprises a lower plate (41), a lower backing plate (42) and a lower die base (43); the bent PIN riveting die is characterized by further comprising a mould rail (3) used for conveying a PIN, wherein the stripper plate (25) is sequentially provided with a riveting die (6), a flattened bending die (8) and a bent rotating die (10). According to the bent PIN riveting die, the manual cost and mechanical cost can be greatly reduced, the stability and efficiency of the production can be improved, and the defective percentage can be reduced.

Description

technical field [0001] The invention relates to a mold, in particular to a bending PIN riveting mold. Background technique [0002] At present, the mold is generally composed of a punch and a die, and can also be composed of multiple punches and multiple dies, but only one punching process can be completed in one stroke of the punch press. For example, the mold for bending and riveting PIN is composed of multiple single-engineering molds to produce a qualified product. The same is true of the molds used now. This mold is not only insufficient in stability, but also wastes manpower and machinery costs. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a bending PIN riveting die with high stability and high production efficiency. [0004] In order to solve the above problems, the present invention provides a bending PIN riveting die, including an upper die and a lower die; [0005] The upper mold includes an upper mold ba...
