Description

technical field [0001] The invention belongs to the technical field of high-precision pipe cut-to-length, and in particular relates to an integrated device for high-precision pipe cut-to-length. Background technique [0002] High-precision pipes, such as high-precision zirconium pipes, high-precision titanium pipes, precision stainless steel pipes, precision copper pipes and precision aluminum pipes, etc., are often used as structural parts, cladding materials, guiding materials, etc. because of their excellent physical and chemical properties Widely used in high-tech fields such as nuclear power, aerospace and military industry. Such pipes usually have extremely high requirements on straightness, internal and external surface quality, dimensional accuracy, end surface quality, and physical and chemical properties. Inspection, etc. Cutting to length is the final process of pipe production and is an irreversible process. If the cutting size or quality is unstable or the effi...

Problems solved by technology

Because the high-precision pipes are thin-walled pipes with small outer diameters, when the first method is used for processing, the control of the sawing feed speed of the circular saw mainly depends on the experience and level of the operator. If the feed speed is too high, it may cause the pipe At the same time, there is a lot of waste generated by cutting, which is easy to cause damage to the inner and outer surfaces of the pipe. This processing method relies too much on the technical level of the operator, and the stability of product quality is difficult to control, which is not conducive to batch production. Production

The second processing method is realized by the integrated equipment for cutting to length, which has high processing precision and stable product quality. The pipe to be processed will be clamped and moved many times, which will easily cause surface scratches, pinches and bruises. The product quality risk is always at a high level, and the principle is very complicated, which leads to high difficulty in equipment structure, design, manufacture and assembly, and the biggest drawback of the equipment is the limited processing capacity, which can only meet the needs of pipes in a small range. processing, which cannot meet the actual production needs, and is relatively highly dependent on the technical level and experience of operators
