Damping fin dragging device and damping fin composite production system

Abstract

The invention discloses a damping fin dragging device. Pay-off devices are arranged above and below a composite table and used for containing aluminum foil coils and isolation paper coils, movable seats of the pay-off devices can transversely move relative to fixed seats, during work, the transverse position of aluminum foil or isolation paper is detected through a position sensor, a signal is transmitted to a drive device, then the aluminum foil coils and the isolation paper coils are driven to move transversely, the output positions of the aluminum foil and the isolation paper are adjusted,and deviation rectifying is achieved; and the aluminum foil and the isolation paper obtained after deviation rectifying can be aligned with a rubber pad, the rubber pad is sandwiched between the aluminum foil and the isolation paper, a damping pad with the two aligned sides is formed, the damping pad is conveyed forwards on the composite table, and no burr problem is generated on the two sides ofthe finally-formed damping pad.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, and further relates to a damping sheet traction device. In addition, the invention also relates to a compound production system for the damping sheet. Background technique [0002] The damping sheet is also called cement or damping block. It is a kind of viscoelastic material attached to the inner surface of the car body. It is close to the steel plate wall of the car body. It is mainly to reduce noise and vibration, that is to say, to play a damping role The effect on the NVH effect of the vehicle. NVH is the English abbreviation of Noise, Vibration, Harshness. It is a comprehensive problem to measure the quality of automobile manufacturing. It gives the most direct and Most superficially, it has a great impact on user experience. [0003] The production of the damping sheet is to press the butyl rubber sheet to the surface of the aluminum foil. At present, it is known that the traction...

AI Technical Summary

Problems solved by technology

[0003] The production of the damping sheet is to press the butyl rubber sheet to the surface of the aluminum foil. At present, it is known that the traction equipment for the production of NVH damping sheet has a low degree of automation. During the production process, the misalignment of the aluminum foil and the butyl rubber sheet is prone to occur, resulting in Burrs appear on both sides, affecting the appearance of the product
