Problems solved by technology

[0002] Uncoiling and blanking automatic production lines are widely used in automobile sheet production lines. In the process of cutting coils into sheets, due to the weight of the coils themselves, the coils tend to bend downward during the feeding process, resulting in scraping and shearing. The cutting edge of the tool will cause scratches on the sheet; at the same time, during the cutting process, some feed rollers that are squeezed by the upper blade are easy to deform, and the irregularly shaped rollers after deformation are also likely to cause scratches on the

Abstract

A plate uncoiling and shearing die comprises an upper die base and a lower die base. A lower die cutter block, an elastic material supporting frame and a discharging roller strip set are sequentially arranged on the top of the lower die base from the feeding side to the discharging side. The lower die cutter block and the discharging roller strip set are fixed to the lower die base, an elastic material pressing device is correspondingly arranged over the lower die cutter block, the top of the elastic material pressing device is connected with the bottom of the upper die base through a material pressing device spring, and the bottom of the elastic material pressing device is matched with the top of the lower die cutter block in a pressing mode. The bottom of the elastic material supporting frame is connected with the top of the lower die base through a material supporting frame spring, an upper die cutter block is correspondingly arranged over the elastic material supporting frame, the top of the upper die cutter block is fixedly connected with the bottom of the upper die base, and the upper die cutter block is matched with the lower die cutter block. According to the design, roll materials are prevented from being scratched by a cutting edge of the lower die cutter block, meanwhile, the die is prevented from being damaged by the edges of the roll materials, and the die maintenance cost is reduced.

Description

technical field [0001] The invention relates to a shearing die tooling, in particular to a sheet material uncoiling shearing die, which is particularly suitable for sheet material shearing. Background technique [0002] Uncoiling and blanking automatic production lines are widely used in automobile sheet production lines. In the process of cutting coils into sheets, due to the weight of the coils themselves, the coils tend to bend downward during the feeding process, resulting in scraping and shearing. The cutting edge of the tool will cause scratches on the sheet; at the same time, during the cutting process, some feed rollers that are squeezed by the upper blade are easy to deform, and the irregularly shaped rollers after deformation are also likely to cause scratches on the sheet. To prevent the roller from scratching the sheet, you can choose a softer non-metallic feeding roller, but the use of a softer non-metallic roller has caused a new problem, that is, when the shee...
