Six-dimensional parallel forging operator

Abstract

A 6D parallelly connected forge machine is composed of 6 linear drive systems fixed to upper platform, and the join mechanism between linear drive systems and platform. Each linear drive system has a vertical column as its guide track and can drive a jointer connected to one end of a connecting rod via a primary spherical hinge. Another end of said connecting rod is connected to the platform via primary spherical hinge. A gripper for grasping the work-piece to be forged is installed to the platform.

Description

technical field [0001] The invention relates to a six-dimensional parallel forging manipulator, which is used for grabbing and operating forging blanks during free forging, and belongs to the field of forging and pressing processing in mechanical engineering. Background technique [0002] The forging manipulator is one of the basic tools for large-scale forging pressure processing, and it is used in conjunction with the press. The current forging manipulators include wire rope suspension type, multi-bar mechanism combined type, etc. The wire rope suspended forging manipulator has a small operating capacity and is used for small-scale forging, while the multi-bar mechanism combined forging manipulator has a large operating capacity and is used for large-scale forging. Generally speaking, the forging operation functions that the forging manipulator needs to realize include jaw clamping, tong bar rotation, tong bar lifting, tong bar pitching, tong bar lateral movement, tong ba...

AI Technical Summary

Problems solved by technology

In the forging manipulator of this patent, during the forging process, the retraction action of the clamp required by the extension and deformation of the forging is completely realized by the walking of the cart, which has a huge moment of inertia, consumes a lot of energy, and is relatively difficult to control; The four actions of pitching, tong bar lateral movement, and tong bar swing are realized by different mechanisms. The structure is complex, the number of parts is large, and the manufacturing cost is high. Moreover, the tonnage of the forging manipulator is small, and it is only suitable for small and medium-sized forging processes.

Through literature search and analysis, the movements of the current forging manipulator, such as lifting and lowering of the forging manipulator, pitching of the tong bar, lateral movement of the tong bar, and swinging of the tong bar, are all realized by combining different mechanisms. The structure is complex, the number of parts is large, and the manufacturing cost is high. And they are all small forging manipulators with low operable tonnage
