Channel prone to the following questions in the shearing process: First, the channel compared with other parts of the two shoulders, relatively thick latest price channel, the required shear force on the 10th channel is also larger price, the more cutting edge wear fast, cutting edge use after a period of time. This part of the relatively large amount of wear and tear, resulting in a larger gap shoulder, shoulder prone to collapse phenomenon; the second is channel legs compared to the waist at the price channel, due to the influence of the shear angle, when the cutting edge wear, the cut When cut legs, cut a small amount, usually cut from the leg cut into a tear, prone to glitches channel leg end face; the third is on the cutting edge down the slope and channel leg finish pass basically the same, so that when the legs substantially simultaneously shear force, shear force is large, cutting edge wear faster, on the one hand the hot-dip leg end cut indentation serious price channel, the other cutting edge after aging, prone channel cut partial tear, burr larger phenomenon. After the two points is the main reason affecting the quality of the channel cut. Surface quality of cold-formed channel equilateral requirements are as follows: 1, the surface may not have bubbles, cracks, scarring, folding, inclusion and face layered, allowing no more than 10% of the nominal thickness slight pits, bumps , indentation, hairline, abrasions and pressed into the oxide scale; 2, surface defects by grinding method allows to clean up, but cleaning up the depth shall not exceed 10% of the nominal thickness; 3, cold-formed welded hollow steel welds may not have open welding, lap welding, burn and severe dislocation; 4, the outer burr welds should be cleared within the burr weld can not be cleared.
