Drawing equipment and process for stainless steel machining

Abstract

The invention discloses drawing equipment and process for stainless steel machining. The drawing equipment comprises a horizontal hydraulic broaching machine, wherein sliding grooves are symmetricallyformed in the inner wall of the horizontal hydraulic broaching machine, a pull disc is embedded in the inner side surface of each sliding groove, a plurality of pull grooves are formed in the surfaceof one side of each pull disc in a penetrating mode, a pull rod used for being connected with a power device is welded to the surface of the other side of each pull disc, and the power device is a hydraulic device; and a front plate is fixed at the front end of the horizontal hydraulic broaching machine through a screw plate, a plurality of circular grooves are formed in the surface of the frontplate in a penetrating mode, and a broach is installed on the inner wall of each circular groove. According to the drawing equipment and process for stainless steel machining, a protection device, a pressure sensor, a reset spring and a protection plate are arranged, the inlet end of the horizontal broaching machine is improved on the basis of the prior art, thus, on the premise that normal work of the horizontal broaching machine is guaranteed, pipes at an inlet, which are not subjected to the action of tension after being broken, are protected, and the problem that construction workers are injured after the pipes fly out is solved.

Description

technical field [0001] The invention relates to the technical field of stainless steel processing, in particular to a drawing equipment for stainless steel processing and a drawing process thereof. Background technique [0002] Stainless steel is the abbreviation of stainless acid-resistant steel, which is resistant to weak corrosive media such as air, steam, water, or has the characteristics of stainless steel; stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as petroleum, natural gas, etc. Gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures; it is also commonly used in the production of various conventional weapons, barrels, and shells etc. Stainless steel pipes can be divided into seamless steel pipes and welded steel pipes; according to the shape...

Problems solved by technology

[0003] China Patent Authorization Announcement No. CN100519025C authorized and disclosed a horizontal broaching machine on July 29, 2009. The technical point is that a differential valve is set between the hydraulic cylinder and the reversing valve. When the rod cavity is fed with high-pressure oil, the moving speed of the hydraulic cylinder piston can be increased by more than two times, which greatly shortens the aftertaste time of the broach and improves the working efficiency of the broaching machine; A mechanical control device is set between the directional valve and the transformation. When the sliding seat moves to the corresponding position, the control device can drive the valve stem of the manual directional valve to move to realize the free directional change of the hydraulic cylinder. It is different from the electromagnetic directional valve. Compared with the reversing device composed of travel switches, it has the advantages of reliable application, convenient adjustment, simple structure, and low cost; in addition, in the prior art, horizontal broaching machines are widely used and the technology is mature, but they are still drawing During the process, due to some non-human factors, pipe fractures occur from time to time. When the pipe fractures, the impact force generated at the fracture due to the disappearance of the tension will cause the pipes not subjected to the tension to fly backwards, causing human injury to the construction personnel.
