Equipment and process for quick cooling forming in production of damping sheets of automobiles

Abstract

The invention relates to equipment and a process for quick cooling forming in the production of damping sheets of automobiles and belongs to the field of fine chemical engineering. The equipment mainly comprises an equipment support, a lower roller and an upper bearing, a lower transmission belt, an upper roller, a lower bearing, an upper transmission belt and the like. By the equipment for quick cooling forming, a process for forming by reducing the temperature is invented. The efficiency of the equipment and the process is far higher than that of simple water cooling and air cooling and combination thereof in the prior art, the cooling effect is good, time consumption is short, the operation can be performed continuously, and the requirements of production can be met completely; and water sources are not wasted, work environment is clean and sanitary, and the heath of operators is facilitated. The equipment can be combined with a production process for the damping sheets of the automobiles in the prior art conveniently, and is easy and convenient to install in production lines and easy to start; and at present, the running state of experimental machines is excellent, and the problem of actual production is solved.

Description

technical field [0001] The invention belongs to the field of fine chemical industry, and in particular relates to a new process and equipment for rapid cooling molding in the production of automobile damping sheets. Background technique [0002] Damping sheets are used in automobile production for the purpose of vibration reduction, sound insulation, and heat blocking. A production method of damping sheet uses asphalt, asbestos, talcum powder, calcium carbonate, etc. as raw materials, through hot melting, blending, rolling and other processes to make thin sheets with a certain thickness and certain elasticity, and then cooling and stamping to obtain different Products of different shapes and sizes. Hot-melt asphalt is the main material, which acts as a bonding and cooling forming agent. In production, it is necessary to cool and form the rolled sheet before stamping. Due to the poor heat dissipation performance of asphalt, the following forms are usually used for cooling ...

AI Technical Summary

Problems solved by technology

The disadvantage of this water cooling process is: due to continuous operation, the cooled billet will bring the cooling water in the cooling pool to the stamping platform

Although this process solves the shortcomings of the above two processes to a certain extent, the process is too long and does not fundamentally solve the drawbacks of the production process
