Abstract

The invention relates to a stamping die in the field of machinery, in particular to a punching and flattening die for producing automobile covering parts. The punching and flattening die comprises a base plate, a clamping-punching device and a flattening device, wherein the clamping-punching device and the flattening device are arranged on the base plate, the clamping-punching device comprises upper die plates and lower die plates which are vertically arranged, the upper die plate and the lower die plate are each provided with a semicircular groove, and a puncher pin is arranged on the upper die plate. The flattening device comprises a lower die, an upper die, a stamping slide block, a flattening slide block, a flattening puncher pin and a spring, a sliding way in a shape of a Chinese character 'ao' is formed in the lower die, the flattening slide block is movably fixed to the sliding way in the shape of the Chinese character 'ao', one end of the spring is connected to the flattening slide block, the other end of the spring is fixed to the lower die, and the stamping slide block is arranged on the upper die. The punching and flattening are simultaneously performed through a set of the die, and the machining precision and production efficiency of products are greatly improved.

Description

technical field [0001] The invention relates to a stamping die in the mechanical field, in particular to a punching and flattening die used for the production of automobile cover parts. Background technique [0002] Automobile panels refer to the surface or internal parts of the space shape made of thin metal plates that cover the engine, chassis, cab, and body. According to function and location, it can be divided into three categories: external covering, internal covering and skeleton covering. They have different characteristics from general stamping parts in terms of process design, mold processing, equipment selection and quality control (dimensional tolerance, shape accuracy, part stiffness, surface quality), etc. The basic processes of stamping forming of automobile panels include: blanking, pre-bending, drawing, trimming, punching, flanging, shaping, etc. (see table). Automobile panels with a typical structure generally require 4 to 6 processes, and some processes ...
