Light alloy wheel powerful spinning machine

Abstract

The light alloy wheel powerful spinning machine of the present invention is composed of a mechanical system, a hydraulic system and an electrical control system, belongs to the closed-loop servo-controlled numerical control forming equipment, and is specially used for the powerful spinning forming of light alloy wheel rims. Its originality lies in: 1) The spinning machine is a vertical C-shaped fuselage structure; 2) The axial feed of the spinning wheel is driven by the servo cylinder installed on the upper part of the C-shaped fuselage to drive the main slider along the machine. 3) The radial feed of the two rotary wheels is realized by driving the radial feed sliders to move radially along the linear guide rails installed on the bottom plate by their respective feed oil cylinders 4) The tail top mechanism is vertically installed on the upper part of the C-type fuselage, and has a guide rod device to prevent the piston rod of the tail top cylinder from rotating; The tightening device drives the main shaft and the lower die to rotate through the synchronous belt; 6) The contact angle between the rotary wheel and the workpiece is adjustable.

Description

technical field [0001] The invention belongs to the technical field of numerical control forming equipment, in particular to spinning forming equipment for light alloy wheel rims. [0002] technical background [0003] At present, the spinning process is more and more widely used in the production of light alloy wheels such as aluminum and magnesium. The spinning process is a processing technology with little cutting. A large degree of plastic deformation is obtained, the mechanical properties and elongation are greatly improved, the defects in the blank are eliminated, and the product weight is reduced. In the wheel manufacturing industry, with the development of the demand for lightweight wheels, the demand for powerful spinning machines is increasing. [0004] At present, some manufacturers at home and abroad have produced some types of spinning machines for aluminum alloy wheels, which are mainly divided into horizontal and vertical structures. For wheel products, the s...

Problems solved by technology

For wheel products, the horizontal spinning machine has the main disadvantages of inconvenient loading and unloading and low production efficiency.

However, the body structure and transmission mechanism of the vertical spinning machine are relatively complicated. Whether it is a spinning machine with two or three wheels, it adopts a multi-column form, and the structure is complicated, resulting in high equipment manufacturing costs and affecting large-scale promotion. application
