A sheet metal uncoiler shearing die

Abstract

An uncoiling and shearing die for sheet materials, comprising an upper die base and a lower die base, and the top of the lower die base is sequentially provided with a lower die cutter block, an elastic support frame and a discharge roller strip from the feeding side to the discharging side The lower die cutter block and the set of discharge rollers are fixed on the lower die base, and an elastic presser is correspondingly arranged directly above the lower die cutter block. The bottom of the upper die base is connected, and the bottom of the elastic presser is press-fitted with the top of the lower die cutter block; An upper die cutter block is correspondingly arranged directly above the 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 and the lower die cutter block are matched. This design prevents the coil material from being scratched by the edge of the lower die cutter block, and at the same time prevents the edge of the coil material from damaging the mold and reduces the maintenance cost of the mold.

Description

technical field [0001] The invention relates to a shearing die tooling, in particular to an uncoiling shearing die for sheet materials, which is particularly suitable for cutting sheet materials. Background technique [0002] The automatic uncoiling and blanking production line is widely used in automobile sheet metal production lines. In the process of cutting the coil material into sheet materials, due to the weight of the coil material, the coil material is easy to bend downward during the feeding process, resulting in scraping and shearing. At the same time, during the cutting process, some feeding rollers squeezed by the upper knife block are easily deformed, and the irregularly shaped rollers after deformation are also easy to cause scratches on the sheet. To prevent the roller from scratching the sheet, you can choose a feeding roller with a softer non-metallic material, but the use of a softer non-metallic material has caused a new problem, that is, when the sheet mo...

AI Technical Summary

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 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 sheet moves forward on the mold, the sheet will The edge will cause cutting damage to the non-metallic roller, which will affect the use of the mold and increase the maintenance cost of the mold

Therefore, the existing sheet material uncoiling and shearing die has the problems that the sheet material is easily scratched and the rollers on the support rack are easily damaged.
