Automatic chamfering, cutting-off and deburring device for steel pipe

Abstract

The invention relates to an automatic chamfering, cutting-off and deburring device for a steel pipe. The device comprises a machine tool, a bracket, a positioning mechanism, an outer corner chamfering mechanism, a cutting-off mechanism, an inner corner chamfering mechanism and a hydraulic cylinder, wherein the bracket is arranged on the machine tool; the positioning mechanism comprises a clamp and an auxiliary clamp; the outer corner chamfering mechanism, the cutting-off mechanism and the inner corner chamfering mechanism are arranged on the bracket; the inner corner chamfering mechanism comprises a cutter, a cutter rest and hinged shafts; the cutter is arranged on the cutter rest; the cutter rest is connected with an axial spindle and a radial spindle of the hydraulic cylinder through the hinged shafts respectively. The automatic chamfering, cutting-off and deburring device further comprises an automatic control system, and the automatic control system is electrically connected with the outer corner chamfering mechanism, the cutting-off mechanism and the inner corner chamfering mechanism. By the adoption of the automatic chamfering, cutting-off and deburring device, only one time of feeding procedure is conducted, and positioning, clamping, outer corner chamfering, cutting-off and inner corner chamfering of other procedures are sequentially and automatically conducted on the machine tool, so that the steel pipe concentric machining precision is improved, and the automatic chamfering, cutting-off and deburring device has the characteristics of being simple in structure, high in degree of automation, high in deburring effect, convenient to use and suitable for batch production and machining.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an automatic chamfering, cutting and deburring device for steel pipes. Background technique [0002] Pipes can be widely used in automobile industry, agricultural machinery, mining machinery, household appliances, electronic instruments, national defense industry and other departments, and play an important role in various fields of national economic construction. At present, in the mechanical processing industry, pipe cutting is a widely used processing method, and the pipe cutting technology can affect the quality and efficiency of mechanical processing. [0003] Existing pipe cutting equipment, especially for steel pipe cutting equipment, can only achieve the integration of chamfering and cutting after many times of transformation, and for steel pipe cutting with high precision requirements, it needs to be transferred to a lathe for lathe processing o...

AI Technical Summary

Problems solved by technology

Although the existing equipment can already meet the blanking requirements for pipe materials such as rollers, for steel pipes with high processing precision requirements, it is generally necessary to chamfer the inner corners, that is, to remove burrs, and the existing equipment cannot meet the high precision requirements. In particular, it is not possible to chamfer the inner wall of the end of the tube to achieve the ability to automatically remove all burrs. For example, the barrel of the barrel feeder requires that the inner and outer walls must be free of burrs and sharp ends. It is necessary to take the cut steel pipe to the lathe for secondary processing, which is time-consuming and labor-intensive, which increases the production cost of the enterprise

At present, the chamfering of the inner hole and the outer peripheral end of the steel pipe is carried out in two steps, that is, the inner hole and the outer peripheral end of the steel pipe are chamfered by different chamfering tools, so that the chamfering process increases, and the production and purchase costs of the tool increase.
