Hot stamping forming production line

Abstract

The invention discloses a hot stamping forming production line. The hot stamping forming production line comprises a press, a combined feeding system arranged on a medial axis on one side of the press, a conveyor belt arranged on the other side of the press, multi-layer heating furnaces arranged on two sides of the combined feeding system and a supply system corresponding to the multi-layer heating furnaces. The combined feeding system is added and mounted on the medial axis of the press, so that simple straight feeding can be realized, and a blank conveying route is shortened; the multi-layer heating furnaces are arranged on two sides of the combined feeding system in opposite directions, accordingly, the combined feeding system can be shared, the product quality is guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of hot stamping forming, in particular to a hot stamping forming production line. Background technique [0002] Thermoforming stamping is to put the blank into a single-layer or multi-layer heating furnace to heat and keep it at 930°C-950°C. After the material is completely austenitized, it is taken out of the single-layer or multi-layer heating furnace and quickly sent to the press. Inside stamping and complete pressure quenching. The higher the temperature of the heated blank at the beginning of stamping and pressing, the more conducive to the formation of martensitic structure inside the product during quenching, so as to ensure the quality of hot stamping products. If the billet is exposed to the air for too long when it is sent out from the multi-layer heating furnace and then transferred to the press mold, the temperature loss of the billet will be too large, and the surface of the non-coated billet will be oxi...

AI Technical Summary

Problems solved by technology

The hot billet passing through the heating furnace on the hot pressing forming production line enters the press under the handling of the second lifting table receiving and discharging robot, although the above production line avoids the original multi-layer heating furnace by using In the hot stamping production line, the picker of the discharging robot needs to directly extend into the furnace of the heating furnace to grab the billet. However, after the discharging robot grabs the billet, it still needs to turn to a certain angle before putting the billet into the press. , or in addition to lifting and forward and backward movements, a movement in the left and right directions is required to feed the blank into the press, resulting in a longer feeding path, resulting in a greater drop in the temperature of the blank, which affects product quality

This problem has been plagued by the existing multi-layer heating furnace hot stamping production line with stable product quality and improved production tempo
