Abstract

The invention provides a punching device for a seamless steel pipe and a machining method using the punching device. The punching device comprises a device body, a hydraulic transmission system and an air spraying mechanism. The device body comprises a machine base platform and a hollow shaft sleeve perpendicularly installed on the upper face of the machine base platform. A punch for punching holes outwards is installed on the side face of the hollow shaft sleeve. A main oil cylinder of the hydraulic transmission system is installed at the bottom of the machine base platform and provided with a main oil cylinder piston rod extending into the hollow shaft sleeve. A punch push block is installed at the top end of the main oil cylinder piston rod. An inclined groove for driving the punch is formed in the side face of the punch push block. The air spraying mechanism comprises a nozzle right opposite to the punch and an air compressor connected with the nozzle. By means of the machining method using the device, the hollow shaft sleeve positions the seamless steel pipe, and the hydraulic transmission system drives the punch to punch holes in the side wall of the seamless steel pipe from inside to outside. Holes are machined in a punching mode, the punching device can be prevented from producing too many burrs, and even the punching device produces a small number of burrs, the burrs are located on the outer wall and can be easily removed.

Description

technical field [0001] The invention belongs to the field of automation equipment, and relates to punching equipment for seamless steel pipes and a processing method using the equipment. Background technique [0002] Seamless steel pipes can be used to manufacture a variety of equipment parts. During processing, it is often necessary to drill holes in the pipe wall, such as the steering housing under the steering wheel in the automobile steering system. The steering housing is one of the core components of the automobile steering system. It is necessary to open several holes for the seamless steel pipe as required during processing. The traditional drilling method is to position the seamless steel pipe on a drilling machine with a fixture, clamp it, and then drill it with a twist drill. [0003] But this traditional drilling method will cause burrs to be left on the inner wall of the seamless steel pipe, and then a process of removing burrs will be added. And because the b...
