The Improved Structure of the Clamp Bar of the Forging Loading and Discharging Machine

Abstract

An improved structure of a claw beam of a forging charging and discharging machine comprises a guide barrel, a telescopic square barrel, a hollow shaft, a pull rod, a clamping oil cylinder, a clamp mechanism, a claw beam rotation driving device, a stand column and a nut and lead screw component, the guide barrel, the telescopic square barrel, the hollow shaft and the pull rod are coaxially arranged, the telescopic square barrel, the hollow shaft and the pull rod are connected with the claw beam rotation driving device to from an combined integral body, the combined integral body can move back and forth along with the movement of the telescopic square barrel, the hollow shaft and the pull rod can rotate in a plane perpendicular to the axial direction of the hollow shaft and the pull rod as a whole, meanwhile, the pull rod moves in the front-and-back direction relative to the hollow shaft, the hoisting mode that a shaft rolling steel wire rope and a lead screw are matched is adopted, and therefore relative to the hydraulic mode, the travel distance of the claw beam in the vertical direction is obviously increased. The movement function of clamping and releasing of a jaw in the clamp mechanism is not influenced, meanwhile, chuck rotation and stretching and contraction of the claw beam can be achieved, the inclination and bending angle and the vertical travel of the claw beam can be improved, the structure is simple, the size is compact, and the performance is stable and reliable.

Description

technical field [0001] The invention relates to the structure of the clamp rod part on the loading and unloading machine used in the forging production process, and belongs to the technical field of mechanical design. Background technique [0002] The domestic forging industry is currently under the dual pressure of overcapacity and the world financial crisis. If enterprises want to survive and develop in the current harsh situation, it is imperative to improve product quality and reduce production costs. Therefore, it is very necessary to improve the mechanization of production and reduce labor intensity and cost. [0003] At present, the loading and unloading machine for forging of automobile wheel hub is used to load the forged steel ingot or billet into the heating furnace, and can take the heated steel ingot or billet out of the heating furnace, and send it to the forging press or forging manipulator. . It is an important equipment in the forging process. The tong ba...

Problems solved by technology

Due to the single action of the clamp rod and poor flexibility, it cannot adapt to multi-angle operations

Although some improvements have been made to the action function of the pliers so far, most of them rely on the crank connecting rod structure, which is not only complex in structure and bulky, but also unable to adapt to frequent impacts of dynamic loads, poor fatigue resistance, and reliability. needs improvement

In addition, the driving form of the lifting and lowering of the clamp rod is hydraulic drive, limited by the formation of the hydraulic rod, the angle and stroke of the lifting and lowering of the clamp rod are limited
