Grading mold male mold device provided with breaking-off-proof hung bolt

Abstract

The invention discloses a grading mold male mold device provided with a breaking-off-proof hung bolt. The grading mold male mold device comprises a male mold (1), a hung bolt (2) and a male mold carrier plate (3); a blind screw hole is formed in the male mold, a hooked convex edge is installed on the upper portion of the hung bolt, and a carrier plate through hole is formed in the male mold carrier plate; after the male mole is connected with the male mold carrier plate, the hung bolt is fixedly connected with the blind screw hole through the carrier plate through hole, a hooked space is formed between the hooked convex edge and the male mold carrier plate, and when unexpended breakage occurs on the male mold, a broken and falling male mold body is hooked by the hung bolt to prevent the broken male mold body from continuously and downwards falling, so that secondary damage is avoided; and by means of the method that damage is controlled to be at a primary place, other parts of the grading mold are fully preserved for repairing, the grading mold male mold device is particularly suitable for an existing technical scheme, which needs male old regular updating, of a breaking-off-proof technical transformation of a grading mold, and thus the grading mold achieves the aims that secondary damage is avoided, and breaking-off-proof technical transformation is facilitated.

Description

technical field [0001] The present invention relates to a progressive stamping die, specifically refers to a progressive die punch device equipped with anti-breakage bolts for preventing the breakage of the current progressive die from the technological transformation of the current progressive die and for eliminating the hidden danger of secondary damage caused by the breakage . Background technique [0002] The progressive stamping die is referred to as the progressive die, and the strip sheet metal material is referred to as the strip material; the progressive die is a multi-station, continuous stamping die that punches the strip material that moves step by step into a sheet metal product. The progressive stamping frequency of the progressive die can reach dozens to hundreds of times per minute. A pair of progressive dies usually has many punches and corresponding dies. In actual work, the punch of the progressive die Due to material fatigue, fractures will occur at the ...

Problems solved by technology

[0004] Since the hanging table method needs to carry out supporting processing and transformation on the punch and the punch carrier plate at the same time, for the progressive die that has been finalized, it is difficult to use the hanging table method to carry out the technical transformation of the anti-break, that is, the current progressive die, the prior art The punch is made of materials resistant to mechanical fatigue, and measures are taken to regularly update the punch to prevent it. Even so, due to the uncertainty of the actual working conditions of the progressive die, the punch still has the possibility of secondary damage due to fatigue breakage Hidden dangers; therefore, for the current progressive die, there are problems and deficiencies in the existing technology, such as the risk of secondary damage caused by breakage, and the difficulty in carrying out technical reforms to prevent breakage
