RESIDUAL STRESS REMOVING METHOD OF BUILDING MATERIAL MANUFACTURED BY FORMING MACHINE AND DEVICE THEREOF

摘要

The present invention relates to a forming machine processing a base plate made of a plate body which is cut in a predetermined size to be a building material and, more specifically, to a residual stress removing device of a building material manufactured by a forming machine so as to prevent deformation of a product by removing residual stress remaining in the product as the product for construction withdrawn from the forming machine passes through the residual stress removing device, which is installed in a withdrawal unit of the forming machine. According to the present invention, the product withdrawn from the forming machine has no residual stress to form and manufacture a product having an accurate size, thereby improving accuracy of the product. Moreover, according to the present invention, the device can be installed in a withdrawal unit of a conventional forming machine to be highly marketable. Further, according to the present invention, the device can be conveniently applied to a size and a thickness of a product manufactured in each forming machine, thereby being simple, shortening working hours, and preventing occurrence of a defective product due to bending and twisting to reduce waste of base materials, labor costs, and unnecessary production costs.;COPYRIGHT KIPO 2015
