Twin-roller type aluminum alloy roller press

Abstract

A double-roller aluminum alloy rolling machine, which presses and rolls the shock absorber cover and the shock absorber seat of the auto parts into a whole. The rolling device is connected to one end of the connecting rod on the piston rod of the rolling cylinder, and the connecting rod The other end of the connecting rod is fixed on the sliding body, and the sliding body is connected with the clamping shaft connected with the bearing and the bearing cover to form a whole; the hemming device consists of a hemming cylinder fixed on the outer cylinder, and a piston of the hemming cylinder The head is connected with a body with rollers, the body is set outside the sliding body, and the outer cylinder and the spray gun are fixed on the cylinder base. Its coaxial fitting and running in the same direction reduce the relative movement between the main body and the sliding body. After the clamping shaft presses the shock absorber cover, the edge is processed and the liquid wax is sprayed instantly to reduce friction. It not only has high processing accuracy, but also eradicates rolling Medium breaks, cracks, and burrs can effectively improve product quality, and the product qualification rate is as high as 99.9%, which greatly reduces production costs. The roller is directly installed on the body without a roller seat, and has a simple and compact structure and a small volume.

Description

technical field [0001] The invention relates to a rolling machine, in particular to a double-roller type aluminum alloy rolling machine for pressing the shock absorber cover and the shock absorber seat of automobile parts, and processing them into a whole by piping. Background technique [0002] Many chipless molding processes are used in the production and processing of auto parts. [0003] However, the existing rolling machines, especially in the process of curling aluminum alloy parts, will cause burrs and fractures on the edges of parts due to the instantaneous extension and high-speed friction. Automotive shock absorbers and aerospace products with higher requirements have higher requirements for high-risk risks, so the defect rate in the manufacturing process is as high as 40%, resulting in the disadvantage of high production costs.
