Description

Technical Field

[0001] This utility model relates to the field of cold drawing machines, and more particularly to an assembled seamless steel pipe cold drawing machine. Background Technology

[0002] Cold-drawn seamless steel pipe refers to a process in which hot-rolled steel pipe or billet is made into seamless steel pipe through cold drawing. The cold drawing process has the characteristics of high precision, high quality and bright surface, and can make the size and shape of steel pipe meet more precise requirements. The manufacturing process of cold-drawn seamless steel pipe generally includes: raw material processing, pickling and rust removal, cold drawing, lubrication, length cutting, cleaning and packaging. Cold-drawn seamless steel pipe can produce steel pipes of various sizes and specifications, and is suitable for various projects and fields.

[0003] According to a patent published on the Internet (authorization announcement number: CN 220426329), a seamless steel pipe cold drawing machine is used. The invention relates to the field of cold drawing machine technology, specifically a seamless steel pipe cold drawing machine. It simplifies and facilitates die replacement, improving the processing efficiency of seamless steel pipes. The machine includes a cold drawing base, a first cold drawing platform at the front of the top of the cold drawing base, and a second cold drawing platform at the rear of the top of the cold drawing base. Both the first and second cold drawing platforms have through holes on their sides, and mounting holes are provided in the middle of both platforms. A die plate is positioned between the first and second cold drawing platforms, with several die holes on the die plate. Several positioning blocks are provided on the side walls of the die plate, each with a positioning hole in its center. A drive shaft is located in the center of the die plate, with a turntable at its front end. Fixing blocks are provided on the side walls of both the first and second cold drawing platforms, with bolts and nuts installed in the center of the fixing blocks. The drive shaft is installed inside the mounting holes. The diameters of the several die holes are all different.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, the nut is unscrewed and the bolt is removed. Then, the turntable is rotated to switch the mold holes on the mold plate. After the replaced mold hole and through hole are aligned, the fixing block and positioning hole are connected by bolts and nuts to fix the mold plate. When processing steel, we need to select the corresponding positioning hole according to its size and diameter. After long-term use of the equipment, the positioning hole will be damaged due to the friction of the steel, which will affect the cold drawing effect of the steel. Therefore, it is necessary to improve the assembled seamless steel pipe cold drawing machine to solve the above problems. Utility Model Content

[0006] In order to overcome the problem that wear and tear on the rotating disc of the assembled seamless steel pipe cold drawing machine after long-term use, which affects the steel pipe processing efficiency.

[0007] The technical solution of this utility model is as follows: an assembled seamless steel pipe cold drawing machine, including a processing base, a fixed base, a fixed connecting plate, a supporting extrusion plate, a rotating handle, a limiting slot, and a processing positioning hole, and also includes a limiting rotating shaft, a rotating disk, threaded bolts, and an adjustment assembly.

A processing positioning hole is opened inside the mold disk. The limiting rotating shaft is rotatably connected inside the connecting limiting plate. A rotating disk is snapped onto the inside of the limiting rotating shaft. Threaded bolts are threadedly connected inside the rotating disk, and the rotating disk is fixedly connected to the inside of the limiting rotating shaft by the threaded bolts.

[0009] Preferably, the limiting rotating shaft has a through hole at the position corresponding to the threaded bolt, and the threaded bolt is threadedly connected inside the limiting rotating shaft. The rotating disk is fixed by the threaded hole opened inside the limiting rotating shaft at the position corresponding to the threaded bolt.

[0010] Preferably, a fixed connecting seat is fixedly connected to the right side of the connecting limiting plate, and a fixing bolt is fixedly connected inside the fixed connecting seat. The fixed connecting seat and the fixing bolt are threaded together to fix the mold plate inside.

The rotating disk is limited to slide in the groove by the groove at the corresponding position of the rotating disk inside the limiting rotating shaft.

[0012] Preferably, the connecting limiting plate has a groove at the corresponding position of the limiting rotation shaft. The limiting rotation shaft is movably connected inside the connecting limiting plate.

A limit fixing block is fixedly connected to the outside of the threaded screw, and the limit fixing block is fixedly connected inside the processing base. A sliding threaded block is threadedly connected to the outside of the threaded screw, and the sliding threaded block is slidably connected inside the processing base. The first motor drives the rotating connecting shaft to rotate, which in turn drives the pulley to rotate. The transmission belt outside the pulley drives the pulley at the other end, causing the threaded screw to rotate and causing the sliding threaded block to slide inside the processing base.

[0014] Preferably, the machining base has a groove at the position corresponding to the sliding threaded block, and the sliding threaded block slides inside the groove. The groove at the position corresponding to the sliding threaded block inside the machining base limits the sliding threaded block when it slides in the groove.
