Claw rod mechanism of forging manipulator

Abstract

The invention relates to a claw rod mechanism of a forging manipulator, which mainly comprises a jaw clamping mechanism and a claw arm rotating mechanism, wherein the jaw clamping mechanism comprises a claw arm (1), a connecting rod (2), a hydraulic piston cylinder (8), a piston rod (9), a thrust bearing A (12), a thrust bearing B (13), a connecting piece (14), a claw shell B (18), a pin A (19), a pin B (20) and a jaw (21); and the claw arm rotating mechanism mainly comprises a deep groove ball bearing (3), a claw shell A (4), a synchronous belt (5), a small belt wheel (6), a rotary driver (7), a claw shell C (10), a large belt wheel (11), the thrust bearing A (12), the thrust bearing B (13), the connecting piece (14), a rotating body (15), a guiding key (16) and a barrel sleeve (17). The claw rod mechanism of the forging manipulator has the advantages of a simple structure, a regular shape of each member and being easy in manufacturing and disassembly; and the piston rod and the oil cylinder have no torque loads so that the claw rod mechanism is high in structural reliability.

Description

technical field [0001] The invention belongs to the field of material processing, and in particular relates to a tong lever mechanism of a forging manipulator. [0002] Background technique [0003] The forging manipulator is one of the key equipment of the large-scale forging production line, and the tong bar is its core component. The clamping mechanism of the clamp rod includes: mechanical type, suction cup type and electromagnetic type. The traditional forging operation tong bar mainly has two functions of tightening and loosening. Modern large-scale forging manipulators, such as German DDS company, Pank company, and Italian Danieli company, can also realize 360-degree rotation of forgings. However, the moment of inertia of the rotary part is large, the dynamic performance is not good, and the torque is applied to the piston cylinder, which easily causes fatigue failure of the pliers rod. Contents of the invention [0004] The purpose of the present invention is to...

Problems solved by technology

The traditional forging operation pliers mainly have two functions of tightening and loosening. Modern large-scale forging manipulators, such as German DDS, Pank, and Italian Danieli, can also realize 360-degree rotation of forgings. However, the moment of inertia of the rotary part is large, the dynamic performance is not good, and the piston cylinder is subject to torque, which may easily cause fatigue failure of the pliers rod.
