我厂在制作加工大型工字钢梁过程中,工字钢梁的上、下翼缘板在焊接后会产生变形,需校正。以往校正变形的工艺是在一根工字钢梁上根据变形情况找出一些点,用火焰加热,然后使其冷却来控制变形;或是用千斤顶校正,同时锤击变形处来控制变形。两种方法都费时、费力、费料,同时还需要经验丰富的老工人才能胜任。而且,经校正后的翼缘还不能达到图纸要求。为此,我们自行设计制造了工字钢梁调直机,采用新的工艺校正翼缘板的变形。
I plant in the production and processing of large-scale I-beam process, the I-beam upper and lower flange plate will produce deformation after welding, to be corrected. In the past, the process of correcting distortion was to find out some points on an I-beam according to the deformation, heat it with a flame, then cool it to control the deformation, or calibrate it with a jack, and hammer the deformation to control the deformation. Both methods are time-consuming, laborious and costly, and also require experienced older workers to be competent. Moreover, the corrected flange can not meet the drawing requirements. To this end, we design and manufacture of I-beam beam straightening machines, the use of new technology to correct flange plate deformation.
