A stamping tool for reducing shape deformation at the edge of automobile stamping sheet

Abstract

The invention provides a stamping tool capable of reducing shape deformation of the edge of a stamped plate of an automobile. The stamping tool comprises a lower die base and an upper die plate. The upper die plate is slidably clamped on guide stand columns and is connected to the telescopic end of a hydraulic cylinder. Outer protection plates are connected to the outer edges of the upper side ofthe lower die base. Two sets of sliding grooves are formed in the lower die base, and inner protection plate frames are slidably mounted on the lower die base through T-shaped sliding blocks and are located on the left side and the right side of a lower die plate. The inner protection plate frames are adjusted according to the size of the lower die plate so as to be attached to the outer side of the lower die plate so that the outer edge of a stamped part of the stamped plate can be supported and protected; the inner protection frames can be kept as high as the lower die plate during stampingunder the effect of a buffer spring set, so that excessive stamping of the stamped edge by the upper die plate is prevented; and when the size of the stamped plate is too large, the outer end of the stamped plate is arranged on the outer protection plates, so that deformation of the stamped edge of the stamped plate is further avoided

Description

technical field [0001] The invention belongs to the technical field of stamping tooling, and more specifically relates to a stamping tooling for reducing shape deformation at the edge of an automobile stamping plate. Background technique [0002] The stamping process is a metal processing method, which is based on the plastic deformation of the metal, using the mold and stamping equipment to exert pressure on the sheet, so that the sheet is plastically deformed or separated, so as to obtain a product with a certain shape, size and performance. parts (stampings). [0003] At present, when using a stamping machine to stamp automobile panels, because the outer edge of the stamping part is not completely placed in the lower template, it is easy to cause deformation at the edge of the stamping part and the lower template, and the stamping is often damaged during processing. Therefore, there is a need for a stamping tool that is easy to adjust and can reduce the deformation of th...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a stamping tool that reduces the shape deformation at the edge of the automobile stamping plate, so as to solve the problem that the outer edge of the stamping part is not completely placed in the lower template, which may easily cause the edge of the stamping part and the lower template Deformation, the stamping die will also be replaced during processing, and a stamping tooling that is convenient to adjust and can reduce the deformation of the edge of the stamping plate is needed
