Chipless cutting and grinding machine for steel pipe

Abstract

The invention discloses a chipless cutting and grinding machine for a steel pipe. The chipless cutting and grinding machine comprises a rack, an adjusting and fixing device, a cutting cutter and a cutter supporting frame. A power device is arranged in the cutter supporting frame. A height adjusting device is arranged at one end of the rack, and a steel pipe supporting device and a control device are arranged at the other end of the rack. The adjusting and fixing device comprises two fixed metal plates, two movable metal plates, an adjusting mechanism and a chipless mechanism. The right side of the power device is in drive connection with a grinding device through a gear case. The rack is provided with a chipping box corresponding to the grinding device. The chipless cutting and grinding machine is simple in structure, reasonable in design, convenient to operate and capable of rapidly and effectively cutting the steel pipe needing to be cut. A fixing function can be achieved for steel pipes with different diameters through simple operation and adjustment, and no fixing device needs to be replaced. During cutting, the steel pipe and the cutter synchronously rotate, and generation of metal chippings is reduced. By means of arrangement of the grinding device, burrs generated due to cutting are removed, and the quality of the cut steel pipe is good.

Description

technical field [0001] The invention relates to the technical field of steel pipe cutting, in particular to a chipless cutting and grinding machine for steel pipes. Background technique [0002] Steel pipe cutting is an industrial operation that is often involved in the production process. When cutting steel pipes, it is not only necessary to be efficient and stable, but also to fix the steel pipes to prevent slipping and rotation during cutting, which will affect the product. quality. [0003] The traditional steel pipe cutting machine is knife cutting, which uses two fixed metal plates to fix the steel pipe, and then cuts it by the knife. The distance between two fixed metal plates is the diameter of the steel pipe. This method is extremely inefficient. Different metal plates need to be set for different types of steel pipes. The conversion is troublesome and the operation is complicated, and the structure is not stable enough. When cutting, it is easy to produce errors a...

AI Technical Summary

Problems solved by technology

The distance between two fixed metal plates is the diameter of the steel pipe. This method is extremely inefficient. Different metal plates need to be set for different types of steel pipes. The conversion is troublesome and the operation is complicated, and the structure is not stable enough. It is also easy to produce errors during cutting, resulting in product failure. Unqualified, resulting in economic loss

At the same time, this cutting method will produce a large amount of metal shavings, and there are many burrs in the cut steel pipe, which makes the material utilization rate low and the machine consumes a lot of energy, resulting in an increase in cost.

When cutting steel pipes, the cutting length cannot be determined, and the cutting surface is easy to be skewed, which wastes a lot of raw materials
