Description

Technical Field

[0001] This utility model relates to the field of cold drawing technology for steel pipes, specifically to an integrated device for cold drawing and heat treatment of stainless steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. Furthermore, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in manufacturing mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware. An existing patent, patent publication number CN210358568U, discloses a cold-drawing heat treatment device for long-distance high-pressure pipe transportation, including a housing. The surface of the housing includes a mounting plate, the lower surface of which is fixedly connected to the upper surface of the housing. The surface includes an elastic rope, the left side of which is fixedly connected to the right side of the mounting plate. Through the coordinated arrangement of the mounting plate, elastic rope, control ring, slider, connecting rod, pipe feeding block, feed block, rubber pad, and fixing rope, the elastic rope connected to the mounting plate generates tension on the surface of the slider, thereby causing the slider to slide to the left at the set slide rail. The elasticity of the elastic rope causes the slider to slide to the right again, thereby causing the rubber pad inside the pipe feeding block to clamp the high-pressure pipe and slide to the right, thus controlling the high-pressure pipe to be conveyed and cold-drawn.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: in practical applications, it is inconvenient to apply oil to the surface of the pipe while it is being drawn, which makes the cold drawing process of the steel pipe cumbersome and reduces the ease of use of the device. Therefore, we have proposed an integrated device for cold drawing and heat treatment of stainless steel pipes to solve the above-mentioned problems. Utility Model Content

[0030] See Figure 4 A limiting component 6 is provided on the upper surface of the base 1. The limiting component 6 includes a limiting block 600 fixedly installed on the upper surface of the base 1. A limiting groove is opened on the top of the limiting block 600. A screw 601 is inserted into one side of the limiting block 600.
