A car door anti-collision beam follow-up cutting device

Abstract

The invention discloses an automobile door anti-collision beam follow-up cut-off device which comprises a supporting seat, a cut-off mechanism, a follow-up mechanism and a plug mechanism. The follow-up mechanism is provided with a sliding table and a follow-up cylinder which drives the sliding table to conduct left-right linear reciprocating motion; the cut-off mechanism is arranged on the sliding table and is provided with a static knife and a moving knife for cutting off an automobile door anti-collision beam; a plug seat and a plug air cylinder are arranged on the plug mechanism; the plug seat is assembled at the workpiece inlet end of the sliding table through a plug seat base plate; the plug air cylinder is mounted on the side portion of the plug seat through a plug air cylinder mounting seat; a plug air cylinder rod is fixedly connected with a plug; and the plug air cylinder drives the plug to move forward to be inserted into a plug hole in an automobile door anti-collision beam workpiece. According to the automobile door anti-collision beam follow-up cut-off device, compared with shutdown cutting-off equipment, the advantages that production efficiency is high, and continuous production is facilitated are achieved; compared with existing servo continuous cutting-off equipment, the advantages of being simple in structure, low in manufacturing and maintenance cost, easy to adjust, stable and reliable in operation and the like are achieved; and in addition, the advantages that cut-off precision is high , and cut-off cumulative errors do not occur are further achieved.

Description

technical field [0001] The invention relates to a cutting device for automobile product parts, in particular to an automobile door anti-collision beam follow-up cutting device used in conjunction with cold bending forming equipment. Background technique [0002] In order to reduce the injuries of occupants in side collisions of vehicles and improve the side collision resistance of vehicles, automobile manufacturers have paid more and more attention to the development and production of door anti-collision beams in recent years. Automobile door anti-collision beam products are mostly products with equal cross-sections, which are suitable for continuous cold-formation processing. After the cold bending forming process, the cutting is completed by the cutting mechanism. The cutting process includes stopping the machine or driving the screw to move the cutting mold through the servo motor, so as to ensure the positioning accuracy of the cutting end. The shutdown and cutting equ...

AI Technical Summary

Problems solved by technology

The shutdown and cutting equipment is relatively simple, but the production efficiency is low, which is not conducive to continuous production, and the frequent start and stop of the motor causes the equipment to bear alternating loads. Long-term operation will reduce the accuracy of the equipment and affect product quality.

The servo system is used to move and cut off, the equipment cost is high, the control method is complicated and difficult to maintain, which increases the equipment debugging time and affects the production efficiency
