A roll forming system for automobile sheet metal parts

Abstract

The present invention relates to a roll forming system, more specifically a roll forming system for automobile sheet metal parts, including a device bracket, a driving motor, a moving bracket, a clamping mechanism, a rolling bracket, a variable diameter mechanism, and an inner rolling mechanism And the outer rolling mechanism, the drive motor drives the two moving brackets to approach or move away from each other, and the two ends of the sheet metal parts are clamped by the clamping mechanism set on the two moving brackets, and are properly released during the rolling process. For a certain length of the sheet metal part, the downward movement of the rolling bracket drives the variable diameter mechanism and the inner rolling mechanism to move downward, and the inner rolling mechanism moves downward to roll the upper end surface of the sheet metal, and the outer roller The pressing mechanism rolls the lower end surface of the sheet metal part. The relative distance between the two reducing mechanisms changes, and the rolling steel plate wrapped between the two reducing mechanisms is squeezed to change its diameter. According to Roll forming arc sheet metal parts with different diameters for different usage requirements.

Description

technical field [0001] The invention relates to a roll forming system, more specifically a roll forming system for automobile sheet metal parts. Background technique [0002] For example, the publication number CN204360844U is a roll forming wire harness production line, which includes a pay-off device, a roll forming system and a stranding machine. The roll forming system includes a frame, a plurality of roll forming machines, and is arranged on the right side of each roll forming machine The rolling pitch disc on the side and the rolling rotary die; the roll forming machine includes a frame with upper and lower rollers, and a plurality of circular grooves are arranged on the roller surfaces of the upper and lower rollers, and the annular grooves on the upper and lower rollers Rolling grooves are formed in one-to-one correspondence; a threading pipe is provided above the upper roller; the rolling pitch disc is composed of a central through hole and a plurality of threading ...
