Intense hot forming production line and hot forming process for boron steel part for automobile

Abstract

The invention relates to an intense hot forming production line and a hot forming process for boron steel parts for an automobile. The intense hot forming production line for boron steel parts for the automobile comprises a feeding robot and is characterized in that box-type furnaces are arranged on the left side and the right side of the feeding robot, an unstacking device and an alignment platform are arranged on the front side of the feeding robot, a press is arranged on the rear side of the feeding robot, a collection device is arranged on the rear side of the press and an automatic unstacking device is arranged on one side of the unstacking device. The hot forming process comprises the following steps: 1. the unstacking device separates boron steel plates or boron steel pipes one by one; 2. the automatic unstacking device transports workpieces to the alignment platform; 3. the feeding robot transports the workpieces from the alignment platform to the box-type furnaces; 4. the workpieces are austenized; 5. the feeding robot takes the workpieces out of the box-type furnaces, transports the workpieces into a die of the press and retracts to the alignment platform; 6. the press presses the workpieces and pressure is maintained for quenching; 7. the workpieces are put in the collection device. The intense hot forming production line for boron steel parts for the automobile and the hot forming process have the advantages that the operation is completed by one robot and the production efficiency and quality of the workpieces are guaranteed.

Description

technical field [0001] The invention relates to an intensive thermoforming production line and thermoforming process of boron steel parts for automobiles, in particular to a thermoforming and quenching process of boron steel plates or / and steel pipes at high temperature and an intensive box furnace production line, belonging to the automobile Plastic forming technology field. Background technique [0002] As an emerging ultra-high-strength hot-formed steel plate, the production process of automotive boron steel plate is divided into 4 stages: [0003] (1) Heating: heating the boron steel plate to the temperature required for heat treatment; [0004] (2) Transmission: transfer the boron steel plate to the die to be stamped; [0005] (3) Forming: such as Figure 1a As shown, it is stamped and formed by a mold at high temperature; [0006] (4) Quenching and cooling: such as Figure 1b As shown, controlling different cooling rates in different regions, can occur: [0007] a...

AI Technical Summary

Problems solved by technology

Although the box-type furnace has the advantage that the workpiece is stationary in the box-type furnace, so that the positioning is accurate, the box-type furnace uses the upper and lower spaces for the workpiece to be vertically discharged in multiple layers, and the space is limited. In order to achieve the same production as the linear drum heating furnace The cycle time, mostly 3-4 box-type furnaces are placed on the feeding side of the press. In order to realize the transportation of the workpiece into the furnace, out of the furnace, and into the press within a certain cycle, it is necessary to arrange the input and removal of the workpiece into the heating furnace. There are at least three automated manipulators, including the robot, the robot that transports the workpiece to the side of the press, and the robot that puts the workpiece into the press. The space is tight, the workpiece transfer time is long and it is difficult to keep warm, and the automation cost also increases.
