Flexible adjustable manipulator for catching high-temperature steel plate

Abstract

The invention provides a flexible adjustable manipulator for catching a high-temperature steel plate. The manipulator consists of a pair finger moving component and an aluminum section framework. The pair finger moving component is driven by a cylinder and drives a drive pin to slide in a sliding chute of a finger connecting piece so as to provide power for the finger connecting piece. A rotation pin is arranged at the middle section of the finger connecting piece and can swing around a counter bore in a rotation bracket so as to finish the opening and closing movement of the finger. The mounting position of the rotation bracket on the aluminum section can be adjusted at will according to the width of the section of steel plate; and the number and mounting position of the pair finger moving component also can be adjusted at will according to the length of the steel plate. Therefore, the manipulator can be used for catching and blanking the steel plate within a certain size range in the hot stamping process, and is particularly suitable for irregular steel plates. Moreover, certain control measures are adopted in the invention to reduce local temperature drop and deformation of the high-temperature steel plate in the transfer process.

Description

technical field [0001] The invention relates to a flexible and adjustable manipulator for grabbing a high-temperature steel plate, which belongs to the field of hot stamping forming. Background technique [0002] Hot stamping forming technology is a process in which the sheet is heated to a high temperature of more than 900 degrees, and then quickly transferred to a mold with cooling function for forming and quenching to obtain ultra-high-strength formed parts. Ultra-high-strength steel formed parts have developed rapidly in recent years, especially in the automotive industry, which has the dual functions of reducing vehicle weight and improving safety. [0003] In the hot stamping automatic production line, it is necessary to quickly transfer the heated high-temperature steel plate from the discharge table to the stamping machine mold by the automatic feeding robot, and the manipulator claw is a particularly critical part of the robot. The steel plate feeding device of the...

AI Technical Summary

Problems solved by technology

At present, there are few manipulators for grabbing high-temperature steel plates. The main method used in foreign hot stamping production lines is to use fingers to distribute around the steel plate, and complete the blank grabbing by grasping and lifting. This method is easier to implement for rectangular blank steel plates. However, , for heterosexual and irregular blanks, it is difficult to realize the distribution and synchronous movement of fingers

The foreign solutions are all special manipulators made for the shape of the billet, which has a narrow range of use and high cost

Domestic hot stamping automation technology started late, and currently there is no mature gripper for grabbing high-temperature steel plates, nor is there any gripper for steel plates of different sizes and irregular shapes within a certain size range
