Hot forming trimming process production line

Abstract

The invention relates to a hot forming trimming process production line. The hot forming trimming process production line comprises a feeding frame and a collection frame. The hot forming trimming process production line is characterized in that a plurality of presses, a feeding device, a discharging device and a conveying device are arranged between the feeding frame and the collection frame; each press comprises an upper worktable surface and a lower worktable surface which are connected through a press stand column, and a hot forming stamping die is installed between the upper worktable surface and the lower worktable surface; the hot forming stamping die comprises an upper die holder, an upper die insert, a lower die insert and a lower die holder, the lower die insert is fixedly arranged on the lower die holder, the upper die insert is fixedly arranged on the upper die holder, a workpiece is positioned between the upper die insert and the lower die insert, and the shape of the lower surface of the upper die insert and the shape of the upper surface of the lower die insert are consistent with the shape of the surface of the workpiece; a cutting edge gap is left between the cutting edge of the upper die insert and the cutting edge of the lower die insert and the width of the cutting edge gap is 7%-20% of the thickness of the workpiece. The hot forming trimming process production line has the advantages that the stamping force can be effectively reduced and the goals of reducing the investment and improving the efficiency are achieved.

Description

technical field [0001] The invention relates to a thermoforming trimming process production line, which belongs to the technical field of thermoforming trimming molds. Background technique [0002] Automobile boron steel parts are a series of hot-formed parts. The production process is divided into two stages: forming and quenching and cooling. Among them: the forming stage needs to be stamped and formed by a mold at high temperature; the quenching and cooling stage needs to control a certain cooling rate. From The transformation of austenite microstructure to martensite microstructure results in extremely high strength and hardness: depending on the type of boron steel, its strength can reach 500-2000MPa. The chemical composition of common boron steels whose strength reaches 1500MPa after hot forming is shown in Table 1. [0003] Table 1 [0004] C Si mn P S Cr B the smallest 0.20 0.20 1.00 - - 0.15 0...
