High-precision oil pipe rapid rotary cutter

Abstract

The invention provides a high-precision oil pipe rapid rotary cutter. The high-precision oil pipe rapid rotary cutter comprises an oil pipe clamping device, an oil pipe pushing device and a rotary cutting device. The oil pipe clamping device comprises an oil pipe positioning block, a pneumatic contact pin and a butt clamping mechanism, and the oil pipe positioning block and the pneumatic contact pin are oppositely arranged. The oil pipe pushing device comprises a sliding table and an air cylinder, the positioning block is connected to the top of the sliding table in a sliding manner, and the air cylinder pushes the positioning block to move. The rotary cutting device comprises a motor, a cutter, a rotating disc and a bush, the motor drives the rotating disc to rotate, one end of the bush is fixedly connected with the rotating disc, the pneumatic contact pin penetrates through the bush, the cutter is arranged beside the pneumatic contact pin, a blade of the cutter is aligned with an annular groove of the pneumatic contact pin, and a cutter holder of the cutter is arranged on the rotating disc. An oil pipe is kept still in the whole rotary cutting process, the distance between the cutter and the center of the oil pipe is kept unchanged, and tipping of the cutter is avoided; and in addition, the pneumatic contact pin not only fixes and positions the oil pipe, but also supports theoil pipe from the inside of the oil pipe, and therefore the oil pipe is effectively prevented from deforming and generating cutting lines.

Description

technical field [0001] The invention belongs to the technical field of oil pipe production equipment, and relates to an oil pipe rotary cutter. Background technique [0002] The oil pipe is a pipeline for transporting gasoline, and it bears the pressure generated during the transportation process, so the wall thickness of the oil pipe is thicker and the hardness is higher. Before assembly, the oil pipe needs to process the end faces at both ends to make the end faces flat so that it can be better assembled with other equipment. The existing oil pipe end face cutting adopts the tangent method, and the tool cuts the end face from top to bottom. However, the oil pipe has high hardness and thick pipe wall, and the end face is prone to cutting lines, and the tool is easy to chip. Therefore, the oil pipe cutting machine needs to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil pipe cutting machine w...
