Problems solved by technology

When the punch material used is SLD high-wear-resistant high-chromium cold work tool steel, and the heat treatment is mainly vacuum treatment, for some molds, such as flanges with one upper and three lower punches, the conventional structure is in the small plate The wall thickness at the position is relatively thin, and deformation often occurs due to the influence of stress during the online cutting process, resulting in deformation and scrapping of the mold, which seriously affects production efficiency and wastes resources

Embodiment Construction

[0024] The invention discloses a process flow for processing a lower punch die. The steps of processing one of the lower punch dies using the process flow of the present invention are as follows: 1) Blanking: select an SLD tool steel billet with a size of ф100*147 for processing; 2 ) Turning process: carry out the turning process on the blank, process the shape of the mold 1 according to the requirements of the drawing, and keep the process head 11 at ф80*5 according to the process requirements, wherein the thickness of the process head 11 is 3~4mm, and the width is 2~5mm. The remaining places are processed according to the process parameters on the design drawings; 3) Marking: mark the processing position and shape on the mold 1 according to the requirements of the drawing; 4) Drilling: process each process hole according to the drawing and the processing technology requirements of mold 1; 5) Heat treatment: conduct heat treatment on mold 1; 6) Wire cutting rough machining: co...

Abstract

The invention discloses a process flow for processing a lower punching die. In the process of processing the lower punching die, the process head is retained to effectively reduce the deformation of the die wall thickness due to stress during the processing, and avoid the deformation of the die due to stress. In the processing process, the deformation is large and the waste generated by scrapping is greatly improved, and the processing accuracy of the mold is greatly improved, which can effectively improve production efficiency and reduce waste.

Description

technical field [0001] The invention relates to a die, in particular to a processing flow of a lower punch die. Background technique [0002] The existing mold manufacturing process is generally as follows: turning→milling marking→NC scribing→drilling→heat treatment→rough grinding→slow [0003] Wire cutting, wire cutting → EDM → slow wire cutting → EDM → research and matching, the front-end processes include turning, drilling, milling, and grinding, and the back-end processes are EDM, CNC milling, fast and slow wire cutting, grinding, etc. After completing the complex curved surface and small hole process, the parallelism of the surface shape is required to reach 10~5μm, and the precision of the small hole is required to be controlled at 1~5μm to ensure the quality of the mold. When the punch material used is SLD high-wear-resistant high-chromium cold work tool steel, and the heat treatment is mainly vacuum treatment, for some molds, such as flanges with one upper and three...
