[0002] A tube drawing machine, also known as a tube drawing machine or a drawing machine, is a mechanical equipment used in the field of metal processing. Its main function is to process metal tubes into tubes with specific sizes and shapes through a drawing process. This equipment is particularly suitable for producing seamless tubes with small diameters and thin walls, as well as high-precision tubes of various alloy materials. The working principle of the tube drawing machine is to place the prefabricated tube blank, which is generally a hollow metal blank that has been forged, rolled or extruded, in a mold, and use external force to pull the tube blank through the mold through a drawing mechanism, so that the tube blank is evenly stressed and continuously plastically deformed, and finally forms a tube of the required size.

[0003] In the prior art, if different pipe diameters are to be targeted, it is necessary to replace the mold that is compatible with the pipe and has holes of different inner diameters. For manufacturers, the production of pipes of various specifications and sizes is a very normal thing. For current manufacturers, storing dozens or even hundreds of sets of molds of different specifications in the factory to adapt to the size of the pipe requires a lot of effort to select, replace, and even store the molds. If the mold is lost, the efficiency and process of the pipe drawing work will be slowed down accordingly.

[0004] Therefore, a continuous pipe drawing device with automatic transfer and position adjustment is proposed to solve or alleviate the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Automatic transfer and adjustment of position to achieve continuous tube drawing device, such as Figure 1 As shown, it includes an electric slide rail 1, an electric slide rail 2 5, and a controller which is a single chip microcomputer. The controller is coupled to the electric slide rail 1 and the electric slide rail 2 5. The two ends of the top surface of the electric slide rail 1 are respectively fixedly connected with a fixed pull rod 2 and a fixed pull rod 2 3. The sliding seat of the electric slide rail 1 is fixedly connected with a reverse scraper 4. The sliding seat of the electric slide rail 2 5 is fixedly connected with a movable pull rod 6. The working movement directions of the movable pull rod 6 and the reverse scraper 4 are set in opposite directions. There are radially adjustable channels in the fixed pull rod 2, the fixed pull rod 2 3, the movable pull rod 6, and the reverse scraper 4.

[0023] like Figure 2-4As shown, the fixed pull rod 1 2, the fixed pull rod 2 3, the movable pull rod 6, and the reverse scraper 4 all include a base 7, a shrinking mechanism arranged on the base 7, and a casing fixedly connected to the base 7 and located outside the shrinking mechanism, and there are an inlet and an outlet penetrating the shrinking mechanism on the casing, and the shrinking mechanism includes two groups of symmetrically arranged primary telescopic parts 12 and secondary telescopic parts 13, a U-shaped frame 1 18 fixedly connected to the movable end of the primary telescopic part 12, a U-shaped frame 20 and a U-shaped frame 3 22 fixedly connected to the movable end of the secondary telescopic part 13, a connecting seat 8 fixedly connected to the base 7, and a fixed connecting A connecting ring 9 and a driving assembly connected to the connecting seat 8, a U-shaped frame 18, a U-shaped frame 20, and a U-shaped frame 3 22 are respectively fixedly connected with a grinding roller 19, a grinding roller 21, and a grinding roller 3 23, the U-shaped frame 18, the U-shaped frame 20, and the U-shaped frame 3 22 are all staggered and distributed, the primary telescopic member 12 and the secondary telescopic member 13 are cylinders, two groups of primary telescopic members 12 and secondary telescopic members 13 are fixedly connected to one end of the connecting tube 11, the connecting tube 11 is rotatably connected to the connecting ring 9, and the driving assembly is transmission-connected to one end of the connecting tube 11 away from the primary telescopic member 12.

[0024] And as Figure 2 As shown, the driving assembly includes a connecting frame 14 fixedly connected to the outer ring of the connecting ring 9, a driving motor 15 fixedly connected to the connecting frame 14, a transmission gear 16 fixedly connected to the output shaft of the driving motor 15, a transmission ring gear 10 fixedly connected to the outer ring of the connecting cylinder 11, and a transmission belt 17 that transmits and connects the transmission gear 16 and the transmission ring gear 10.

[0025] When the automatic transfer and adjustment position is used to realize the operation of the continuous pipe pulling device, it is only necessary to pass the pipe through the fixed pull rod 2, the reverse scraper 4, and the fixed pull rod 3, so that one end of the pipe can be fixed by the movable pull rod 6, and then the electric slide rail 25 drives the movable pull rod 6 to move toward the end away from the fixed pull rod 3, so that the movable pull rod 6 will pull the pipe to pull the pipe. In this process, the pipe will pass through the fixed pull rod 2 and the fixed pull rod 3, and the controller will also control the electric slide rail 1 to drive the reverse scraper 4 on its slide seat to move in the opposite direction. The displacement direction of the reverse scraper 4 is completely opposite to the displacement direction of the movable pull rod 6, that is, It scrapes the pulled tube in reverse, so that it maintains a more straight shape. After such action is completed, the electric slide rail 1 and the electric slide rail 2 5 controlled by the controller are both in the maximum displacement process. At this time, the controller will control the first-level telescopic part 12 and the second-level telescopic part 13 of the shrinking mechanism to expand the diameter of the shrinking mechanism, and make the reverse scraper 4 and the movable pull rod 6 on the electric slide rail 1 and the electric slide rail 2 5 move in reverse, so that the reverse scraper 4 and the movable pull rod 6 reach the initial position, and then the controller controls the shrinking mechanism in the reverse scraper 4 and the movable pull rod 6 to reduce the diameter, squeeze the outer wall of the tube, and perform the next action again.

[0026] When the shrinking mechanism among the fixed pull rod 1 2, the reverse scraper 4, the fixed pull rod 2 3, and the movable pull rod 6 needs to be adjusted, it is only necessary to control the first-stage telescopic member 12 and the second-stage telescopic member 13 of the cylinder through the controller to drive the U-shaped frame 1 18, the U-shaped frame 20, and the U-shaped frame 3 22, as well as the grinding roller 1 19, the grinding roller 21, and the grinding roller 3 23 thereon to move, and then adjust the radius of the inscribed circle between the grinding roller 19, the grinding roller 21, and the grinding roller 3 23, that is, The caliber adjustment of the shrinking mechanism can be completed, and then the driving motor 15 is started to drive the transmission gear 16, and the transmission ring gear 10 is driven to rotate through the transmission belt 17. When the transmission ring gear 10 rotates, it will drive the connecting tube 11 to rotate in the connecting ring 9. When the connecting tube 11 rotates, it can drive the primary telescopic part 12 and the secondary telescopic part 13 to rotate, so that the grinding roller 19, the grinding roller 21, and the grinding roller 3 23 can grind the steel pipe in the process of pulling the rod, thereby ensuring its surface is smooth.
