Description

Technical Field

[0001] The invention relates to the field of stainless steel pipe production drawing technology, in particular to a drawing tool for producing small-diameter stainless steel pipes. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instruments, etc. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. The drawing production process is adopted, and the inner surface roughness of the steel pipe can reach RaMax0.35um. After bright annealing, the steel pipe has very good anti-oxidation properties and mechanical properties, and there will be no scratches, bamboo prints and other defects on the inner and outer surfaces. It is mainly used in clean pipelines in the health, electronics, special gas and other industries;

[0003] When the stainless steel pipe is being drawn, a shaped rod needs to be inserted into the stainless steel pipe to avoid unevenness during drawing. However, after the stainless steel pipe is drawn, the inner wall of the stainless steel pipe will squeeze the surface of the rod, making it difficult to remove the rod from the inside of the stainless steel pipe. Summary of the invention

[0004] The purpose of the present invention is to provide a drawing tool for producing small-diameter stainless steel pipes to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a drawing tool for producing small-diameter stainless steel pipes, comprising a base frame, a drawing frame is fixedly connected to the top of the base frame, a drawing hole is opened inside the drawing frame, a supporting leg is fixedly connected to the bottom of the base frame, a slide plate is fixedly connected to the inner wall of the base frame, a clamping component is arranged on the top of the base frame, and a drawing component is arranged on the end of the base frame;

[0007] The clamping component includes a slide, the inner wall of the slide is slidably connected to the surface of the skateboard, the top of the slide is fixedly connected with a bracket, the end of the bracket is fixedly connected with an electric push rod, the output end of the electric push rod is fixedly connected to a limiting frame, the top of the bracket is slidably connected with a contact plate, the end of the contact plate is slidably connected with a positioning plate, the surface of the positioning plate is fixedly connected with a stabilizing plate, the surface of the stabilizing plate is slidably connected with a clamping plate, the clamping plate and the contact plate are fixedly connected via a spring sheet, the top of the clamping plate is fixedly connected with an inclined plate, the upper surface of the limiting frame is fixedly connected with an extrusion plate, the surface of the limiting frame is fixedly connected with a fixing frame, the surface of the fixing frame is fixedly connected with an electric telescopic rod, and the end of the electric telescopic rod away from the fixing frame is fixedly connected to the positioning plate.

[0008] Furthermore, the top of the limit frame extends above the clamping plate, the bottom of the extrusion plate contacts the top of the inclined plate, the limit frame is arranged at one end of the positioning plate away from the contact plate, and the end of the clamping plate contacts the surface of the positioning plate.

[0009] Furthermore, the slide is symmetrically arranged with the bracket as the center, the electric telescopic rod is arranged at an end of the positioning plate away from the clamping plate, and the electric push rod is arranged below the contact plate.

[0010] Furthermore, the pulling component includes a hydraulic rod, an end of the hydraulic rod is fixedly connected to the inner wall of the base frame, the output end of the hydraulic rod is fixedly connected to a linkage frame, the top of the linkage frame is fixedly connected to a support plate, the top of the support plate is fixedly connected to a round hole frame, the top of the support plate is fixedly connected to a side plate, the surface of the side plate is rotatably connected to a conical frame, the surface of the linkage frame is fixedly connected to a hydraulic telescopic frame, the end of the hydraulic telescopic frame away from the linkage frame is threadedly connected to a center rod, the end of the base frame is fixedly connected to a rectangular block, the surface of the linkage frame is fixedly connected to a telescopic rod, and the end of the telescopic rod away from the linkage frame is fixedly connected to the bracket.

[0011] Furthermore, one end of the center rod away from the hydraulic telescopic frame is slidably connected to the inner wall of the circular hole frame and extends to the outer end of the circular hole frame, and the hydraulic telescopic frame is arranged at one end of the linkage frame away from the hydraulic rod.

[0012] Furthermore, one end of the rectangular block away from the base frame passes through the linkage frame and extends to the outer end of the linkage frame, and the surface of the rectangular block is slidably connected to the inner wall of the linkage frame, and the hydraulic rod is arranged at one end of the base frame away from the slide plate.

[0013] The present invention has the following beneficial effects:

[0014] After the present invention inserts the stainless steel tube into the drawing hole through the drawing component, the electric telescopic rod is used to push the positioning plate to slide on the surface of the contact plate. When the positioning plate moves, the clamping plate pushes the inclined plate to contact the extrusion plate. When the inclined plate moves, the clamping plate uses the inclination of the extrusion plate to push the clamping plate to move toward the top of the contact plate. At this time, the stainless steel tube can be clamped and fixed by the clamping plate, thereby improving the stability of the stainless steel tube when clamping. When the stainless steel tube needs to be separated from the surface of the center rod, the electric push rod is used to push the limit frame to move. When the limit frame moves, it pulls the positioning plate to move toward the end away from the drawing hole, and the positioning plate can push the contact plate to move synchronously through the pressure of the clamping plate. When the clamping plate and the contact plate move, they pull the stainless steel tube to move, so that the stainless steel tube can be separated from the surface of the center rod, thereby improving the convenience of drawing the stainless steel tube.

[0015] After the stainless steel pipe is placed on the inner wall of the conical frame, the hydraulic telescopic frame pushes the center rod into the interior of the stainless steel pipe. In fact, the support plate is pushed toward the end of the base frame by the hydraulic rod, and the support plate can push the stainless steel pipe into the interior of the drawing hole through the circular hole frame to draw the stainless steel pipe. When the linkage frame moves, it pushes the slide to move through the telescopic rod, so that the clamping component can also pull the end of the stainless steel pipe outward, further improving the stability of the stainless steel pipe during the drawing process.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
