Forming mold and forming method of sheet metal machining

Abstract

The invention provides a forming mold of sheet metal machining. The forming mold comprises an upper mold body and a lower mold body. An upper mold plate and a lower mold plate are provided with machining tools used for sheet metal continuous machining procedures. Each machining tool comprises a convex mold and a concave mold. The convex molds and the concave molds are sequentially arranged on the upper mold plate and the lower mold plate according to the sequence of the continuous machining procedures. The positions, on the upper mold plate and the lower mold plate, of the convex mold and the concave mold of each machining tool correspond to each other. The invention further provides a forming method of sheet metal machining. Three punching machining procedures, a longitudinal cutoff machining procedure, a punching machining procedure, a longitudinal bending machining procedure, a longitudinal flattening machining procedure, a transverse cutoff machining procedure, a transverse bending machining procedure and a transverse flattening machining procedure are successively included according to the sheet metal continuous machining procedures. By means of the mold and the method, the sheet metal continuous machining procedures can be reasonably arranged, the speed and efficiency can be increased, the quality and the forming quality of later finished products can be guaranteed, and the sheet metal machining difficulty can be reduced.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, and more specifically relates to a forming die for sheet metal processing and a forming method thereof. Background technique [0002] In sheet metal processing, processes such as punching, bending and flattening are indispensable. Sheet metal processing includes traditional cutting and blanking, punching, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, and new stamping processes. technology and new technology. [0003] At present, the processing molds used in the existing sheet metal processing procedures are all processing tools for installing and processing one of the procedures, so that the processing molds can only complete one processing procedure independently. For example, the existing processing mold is only provided with a punch for punc...

AI Technical Summary

Problems solved by technology

For example, the existing processing mold is only provided with a punch for punching or a punch for bending, etc., so that not only the processing speed is slow and the processing efficiency is low when processing continuous multiple processes, but also the semi-finished products need to be constantly replaced. The operation is cumbersome and complicated; and due to the continuous replacement of processing tools and the need to adjust the processing position of the tool every time the tool is replaced, the processing accuracy is greatly reduced, which affects the quality of sheet metal processing and the quality of subsequent finished products.
