Products made from stainless steel tubing are common in people's real life, as: chairs made of stainless steel pipes, clothes hangers made of stainless steel pipes, stainless steel pipe stair handrails, stainless steel pipe doors and windows and the like. The stainless steel pipe cutting process is a necessary processing procedure when people manufacture stainless steel pipe products, and the stainless steel pipe cutting can also be divided into the following steps according to different cutting tools: common abrasive wheel cutting of stainless steel pipes, circular saw cutting of stainless steel pipes, laser cutting of stainless steel pipes and the like. The stainless steel pipe cut by the common grinding wheel has large size error, and the cut has a plurality of burrs; the effect of the stainless steel pipe cut by the stainless steel circular sawing machine is better than that of the stainless steel pipe cut by a common grinding wheel, the error in size is small, and burrs are few; the stainless steel tube has better laser cutting effect, has small error, and can cut R openings, cut holes, open grooves, carve characters and the like according to the requirements of customers. More and more customers select stainless steel pipe laser cutting processing because the technological effect of laser cutting itself is good, can satisfy a lot of processing requirements of customer moreover, still because present labour cost is high, laser cutting quantity is fast again and the price is reasonable, if deposit manual polishing, the time is long, also very takes the manpower. However, in the process of cutting stainless steel by laser, the stainless steel tube is out of round and deformed, which is mainly shown in the following steps:
firstly, when a tool clamp clamps a stainless steel tube raw material, if the clamp is not tight, the stainless steel tube raw material cannot rotate as required in the laser cutting process, the cutting defect and the quality of the stainless steel tube are abnormal, and if the clamp is too tight, the stainless steel tube raw material is out of round and deformed in the clamping process;
secondly, in the process of cutting the stainless steel pipe by laser, the stainless steel pipe product is gradually cut and separated from the stainless steel pipe raw material body, but the stainless steel pipe product which is already cut by laser but is not cut is still rotated at high speed, and under the condition, the cut stainless steel pipe which is not cut is not effectively supported, the stainless steel pipe product is out of round and deformed;
thirdly, in the process of collecting the stainless steel pipes after laser cutting, the stainless steel pipes are deformed due to out-of-round due to careless operation, for example, the stainless steel pipes directly and freely fall to collide with the ground or a rigid collecting system, or large collision occurs between adjacent stainless steel pipe products, and the like.
