A loading and unloading machine for forging automobile wheel hubs

Abstract

The invention provides a charging and discharging machine for forging of an automobile hub. The charging and discharging machine for forging of the automobile hub comprises a bearing square tube, a clamping oil cylinder, a pull rod, a clamp mechanism, a lifting oil cylinder, a telescopic square tube, a hollow shaft and a clamp beam rotation driving device. The bearing square tube, the telescopic square tube, the hollow shaft and the pull rod are arranged in a mutually sleeved mode from outside to inside in sequence, so that stretch and retreat motion of a clamp beam is achieved. Meanwhile, the hollow shaft is connected with the clamp beam rotation driving device, the pull rod is matched with the hollow shaft with respect to profiles, and therefore rotation of a clamp head is achieved. According to the charging and discharging machine for forging of the automobile hub, a hydraulic and mechanical mixed transmission mode is adopted, use of a complicated crank connecting rod structure is reduced to the maximum extent, and therefore the clamp beam and the clamp head can complete stretch, retract, rotation, clamping, releasing and other motions. The charging and discharging machine for forging of the automobile hub has the advantages of being simple in structure, good in reliability, stable in motion, capable of being adapted to a frequently dynamic load, high in efficiency, good in safety performance, capable of remarkably saving energy and the like.

Description

technical field [0001] The invention relates to a loading and unloading machine used for loading and operating materials during the forging production of automobile wheel hubs, and belongs to the technical field of mechanical design and automation. 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. Furnace loading and unloading tongs are the furnace loading and unloading tools used in the early stage of our country. It can complete the loading and unloading of tens to hundreds of kilograms of heavy workpieces. It has simple structure, low cost, and the manufacturing cost of the matching chamber heating furnace. Low, high therm...

AI Technical Summary

Problems solved by technology

However, the orbital loading and unloading machine also has its limitations, mainly in: the main body of the clamp rod unit is a crank connecting rod structure, the action accuracy is low, it cannot withstand frequent dynamic loads, poor fatigue resistance, and difficult maintenance

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