[0002] As the main structural part of tower crane, the integral standard section is in great demand in the production of tower crane. The main limb of the standard section is generally made of square tube as raw material, so a large amount of square tube raw material needs to be invested in production. In order to make full use of raw materials, reduce the waste of raw materials, and effectively control production costs, it is necessary to reduce the length of the remaining tail material as much as possible during the square tube sawing process. At present, the circular saw machine of the cutting equipment needs to clamp the tail material length ≥150mm in the process of the finished product of the last section of the main limb to meet the normal operation cutting, which has the defect of raw material waste. In order to further reduce the tail material and ensure the cutting accuracy, it is necessary to design a square tube cutting clamping device.

The profile cutting machine is provided with a second locking device on the second positioning part that can lock the second positioning part on the frame, and a baffle that can block the head of the strip profile is provided on the first positioning part. The positioning device not only simplifies its structure, but also proposes that the position of the positioning device can be adjusted conveniently and accurately. However, the profile cutting machine has the following defects;

However, lateral support is performed during the cutting of tailings. This results in poor support firmness and shaking of the profile tailings caused by cutting if only lateral support is relied upon during the cutting process. Therefore, an automatic support device for saving profile cutting tailings is provided. Utility Model Content
