Description

Technical Field

[0001] The invention relates to the technical field of copper tube drawing, in particular to a copper tube drawing device. Background Art

[0002] Copper tube drawing is a process for processing copper tubes. Through drawing, the copper tube can be stretched and reduced to reach the specified size and shape, and protrusions can be provided in the drawing holes to make the outside of the copper tube have patterns to increase its aesthetics. Copper tube drawing has the advantages of high production efficiency, good processing quality, and high material utilization rate. Therefore, copper tube drawing is widely used in the manufacture of pipelines, wires, automotive parts and other fields. Through the copper tube drawing process, high-precision and high-quality copper tubes can be manufactured to meet various industrial needs.

[0003] At present, the patent with announcement number CN112246899A discloses a low-frequency drawing device for a thin-walled copper tube, comprising a fixed plate and a rotating device, the fixed plate is in a "U" shape, the surface of the fixed plate is slidably connected with a second push plate, and the second push plate is in a "T" shape, the surface of the second push plate is provided with a rotating device, the rotating device comprises a circular ring, the surface of the circular ring is fixedly connected to the second push plate, the inner wall of the circular ring is rotatably connected with a disc, and the end of the disc away from the second push plate is provided with a circular groove, the inner wall of the disc is fixedly connected with two fixed blocks, and the two fixed blocks are in an "L" shape, the short arm end of the fixed block is fixedly connected with a spring, the end of the spring away from the fixed block is fixedly connected with the second clamping plate, the side of the fixed block close to the second clamping plate is fixedly connected with the first clamping plate, the end of the disc away from the fixed block is fixedly connected with a cylinder, the surface of the cylinder rotates through the interior of the second push plate, and the end of the second push plate away from the disc is fixedly connected with a hand. By setting a rotating device, when the copper tube needs to be checked, the copper tube is first pushed so that the tube wall of the copper tube squeezes the second clamping plate. At this time, the copper tube is released, so that the spring continues to push the second clamping plate due to the recovery of elastic force, so that the second clamping plate clamps the copper tube between the second clamping plate and the first clamping plate. At this time, the handle is turned to make the handle drive the cylinder to rotate, so that the disc rotates on the inner wall of the ring with the help of the force of the rotation of the cylinder. At this time, the copper tube clamped between the second clamping plate and the first clamping plate will rotate with the disc, and whether there are defects on the surface of the copper tube can be checked at this time.

[0004] However, the following problems still exist in the current copper tube drawing process: When the above-mentioned device is used, it detects whether there are defects on the copper tube before drawing. However, during the drawing process of the copper tube, defects may appear on the copper tube, thereby affecting the aesthetics and practicality of the copper tube. In the process of detecting the copper tube, more manual steps are required, which is very time-consuming and labor-intensive. Summary of the invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments.

[0021] When the copper tube needs to be drawn, the copper tube is passed through the drawing hole opened in the middle position of the drawing plate 15 (before the copper tube passes through for the first time, the head end of the copper tube needs to be squeezed so that it passes through the drawing hole, and no processing is required for subsequent drawing), and then the extrusion plate 13 is located inside the copper tube, and the clamping plate 10 is located outside the copper tube. Then the clamping telescopic rod 9 starts to work, because the clamping telescopic rod 9 is fixedly mounted with the clamping plate 10. At this time, the clamping plate 10 starts to move toward the direction close to the copper tube until it fits tightly with the outer surface of the copper tube, and then the extrusion telescopic rod 12 starts to work, and the extrusion telescopic rod 12 starts to drive the extrusion plate 13 to move until the extrusion plate 13 fits tightly with the inner surface of the copper tube (the clamping telescopic rod 9 and the extrusion telescopic rod 12 are both configured as telescopic rods driven by hydraulic pressure). The copper tube can be clamped and fixed, and then the first motor 2 starts to work, and the first motor 2 starts to drive the conveyor pulley 3 to rotate. At this time, the movable plate 4 starts to move to the right (as the movable plate 4 moves to the right, the extension plate 5 fixedly installed on the movable plate 4 also starts to move to the right, that is, the positioning wheel 6 starts to roll on the walking track 7). Because the copper tube is clamped and fixed on the movable plate 4 by the clamping plate 10 and the extrusion plate 13, the copper tube begins to be pulled to the right at this time, that is, the copper tube is pulled when passing through the drawing hole opened in the middle position of the drawing plate 15. When the copper tube is pulled to the specified length, the hydraulic rod 17 starts to work, because a cutting knife 18 is fixedly installed on the upper end of the hydraulic rod 17, and the cutting knife 18 starts to slide along the installation plate 16 at this time, that is, the movement of the cutting knife 18 can realize the cutting of the drawn copper tube.

[0022] Two side panels 19 are fixedly installed on the rear side of the workbench 1, and driven gears 20 are rotatably installed on both side panels 19, and a pulley group 21 is coaxially installed on the driven gear 20, a damping shaft 22 is fixedly installed on the pulley group 21, and a guide plate 23 is fixedly installed on the damping shaft 22, a gear tooth structure is arranged on the outside of the extension plate 5, and the extension plate 5 is meshed with the driven gear 20 through the gear tooth structure, one side of the pulley group 21 is coaxially connected to the driven gear 20, and the other side of the pulley group 21 is coaxially connected to the guide plate 23.

[0023] exist Figure 1When the moving plate 4 in the figure moves from left to right, the extension plate 5 installed on the moving plate 4 also starts to move to the right, because the extension plate 5 is provided with a gear structure, and the extension plate 5 is meshed with the driven gear 20, at this time the driven gear 20 starts to rotate counterclockwise, because the driven gear 20 is meshed with the pulley set 21, at this time the pulley set 21 also starts to rotate counterclockwise, because the pulley set 21 is coaxially connected with the damping shaft 22, at this time the damping shaft 22 starts to rotate counterclockwise, because the upper end of the damping shaft 22 is fixedly mounted with a guide plate 23, at this time The guide plate 23 begins to rotate counterclockwise, that is, the guide plate 23 rotates to the position of the upper end of the conveyor pulley 3. At this time, the lower end of the drawn copper tube begins to fit together with the upper end of the guide plate 23. As the copper tube is cut off, the copper tube is rolled into the placement box 24 under the action of the slope set on the upper surface of the guide plate 23. When the movable plate 4 moves from right to left, the driven gear 20 rotates clockwise, that is, the pulley group 21 and the guide plate 23 also begin to rotate clockwise. At this time, the guide plate 23 rotates to the side position of the workbench 1 to avoid affecting the passage of the movable plate 4.

[0024] A placement box 24 is fixedly installed on the front side of the workbench 1, an assembly plate 30 is fixedly installed on the left end of the front side of the workbench 1, and a second motor 31 is fixedly installed on the assembly plate 30, a first gear 32 is installed on the output end shaft of the second motor 31, and a second gear 33 is meshed with the upper end of the first gear 32, a connecting shaft 34 is fixedly installed on the output end of the second gear 33, a second electric telescopic rod 36 is fixedly installed on the left side of the placement box 24, a driving plate 35 is fixedly installed on the second electric telescopic rod 36, and a left plate 37 is fixedly installed on the connecting shaft 34, a reciprocating screw 39 installed on the first gear 32 is provided with a visual inspection device 40, two fixed rods 25 are symmetrically arranged on the upper end of the placement box 24, and a vortex spring 26 is fixedly installed on the outer surface of the fixed rod 25, and the other end of the vortex spring 26 is fixedly installed on the shock absorbing plate 27, and the shock absorbing plate 27 is set as a long strip plate structure, and the placement box 24 is on the right side of the middle. A first electric telescopic rod 28 is fixedly installed in a position, and a push plate 29 is fixedly installed on the first electric telescopic rod 28, and an inclined groove is arranged on the push plate 29, and the outer surface of the push plate 29 is set to be smooth, and a trapezoidal groove is opened on the placement box 24, and the push plate 29 is slidably connected with the placement box 24 through the trapezoidal groove opened on the placement box 24, a bearing and a rotating shaft are installed on the right side of the placement box 24, and a right plate 38 is fixedly installed on the rotating shaft, and the outer surface of the right plate 38 is set to be matte, a threaded hole is opened in the middle position of the visual inspection device 40, and limiting holes are symmetrically opened on the front and rear sides of the threaded hole, the reciprocating screw 39 is threadedly connected with the visual inspection device 40 through the threaded hole opened on the visual inspection device 40, a guide rod 41 is fixedly installed on the assembly plate 30, and the guide rod 41 is slidably connected with the visual inspection device 40 through the limiting hole opened on the visual inspection device 40.

[0025] As the cut copper tube falls into the placement box 24, the copper tube begins to contact the shock absorbing plate 27. The upper end of the shock absorbing plate 27 is set to a soft rubber material. At this time, the shock absorbing plate 27 begins to rotate around the fixing rod 25, that is, the vortex spring 26 begins to be stretched and deformed. Under the action of the shock absorbing plate 27, the direct collision between the copper tube and the lower end of the placement box 24 can be avoided, so as to achieve the purpose of protecting the placement box 24 and the copper tube. As the copper tube falls to the lower end of the placement box 24, under the action of the vortex spring 26 restoring the deformation, the shock absorbing plate 27 begins to return to the starting position, and then the second electric telescopic rod 36 starts to work, because the second electric telescopic rod 36 The driving plate 35 is connected to each other. At this time, the driving plate 35 begins to move toward the placement box 24, because the connecting shaft 34 is rotatably installed in the middle position of the driving plate 35. At this time, the connecting shaft 34 begins to drive the second gear 33 to move toward the placement box 24 until the left plate 37 is tightly fitted with the left side of the copper tube. At this time, the right plate 38 begins to tightly fit with the right side of the copper tube, and then the second motor 31 starts to work. Because the output end of the second motor 31 is connected to the first gear 32, the first gear 32 begins to rotate. Because the first gear 32 and the second gear 33 are meshed with each other, the second gear 33 starts to work. The second gear 33 starts to rotate, that is, the second gear 33 starts to drive the connecting shaft 34 and the left plate 37 to rotate, and the copper tube tightly fitted with the left plate 37 also starts to rotate. At the same time, because the reciprocating screw 39 is fixedly installed on the first gear 32, the reciprocating screw 39 also starts to rotate. Because the reciprocating screw 39 is connected to the visual inspection device 40 through the threaded hole provided on the visual inspection device 40, the visual inspection device 40 starts to move to the right under the guidance of the guide rod 41. At this time, the lower end of the copper tube can be inspected for defects. Because the copper tube is always in a rotating state, the outer surface of the copper tube can be fully inspected. After the detection is completed, the first electric telescopic rod 28 starts to work. Because the first electric telescopic rod 28 is equipped with a push plate 29, the push plate 29 starts to fit with the copper tube and push the copper tube. Because the push plate 29 is installed at a position slightly to the right of the center, the right side of the copper tube starts to be pushed up, the damping plate 27 starts to rotate in the opposite direction, and the vortex spring 26 starts to be squeezed and deformed (the performance of the vortex spring 26 and the service life of the vortex spring 26 can be effectively guaranteed through the alternating squeeze deformation and stretch deformation of the vortex spring 26). At this time, the copper tube that has been tested can be taken out to complete the drawing process of the copper tube.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
