Problems solved by technology

[0002] At present, when the plate bending product with a degree of less than 90 degrees is formed, it is processed by stamping and bending. After bending, the product is wrapped on the bending block of the stamping die, which is inconvenient for feeding. After prying it off from the bending block with a special tool The product is deformed, causing the product to be scrapped or the processing time is long

Abstract

The invention discloses a negative angle bending mould which comprises an upper mould and a lower mould. The upper mould comprises an upper press plate and a punch. The lower mould comprises a first slide block, a second slide block, a guide rail, a base seat and a baffle, wherein a square hollow cavity is formed in the base seat, the first slide block and the guide rail are placed on the inner left side of the base seat in a stacked mode, the second slide block is placed on the inner right side of the base seat, and the baffle is placed between the first slide block and the second slide block through a first compression spring. Through the method, the negative angle bending mould can improve stability of product size processing and improve processing efficiency.

Description

technical field [0001] The invention relates to the technical field of metal stamping dies, in particular to a negative-angle bending die. Background technique [0002] At present, when the plate bending product with an angle of less than 90 degrees is formed, it is processed by stamping and bending. After bending, the product is wrapped on the bending block of the stamping die, which is inconvenient for feeding. The product is deformed, causing the product to be scrapped or the processing time cycle is long. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a negative angle bending die, which can improve the stability of product size processing and improve processing efficiency. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a negative angle bending die, including an upper die and a lower die, the upper die includes an upper platen and...
