Description

Technical Field

[0001] This utility model relates to the technical field of copper rod production drawing device, and more particularly to a copper rod production drawing device. Background Technology

[0002] Copper rods are long, thin metal materials made of high-purity copper. Due to their excellent electrical and thermal conductivity and mechanical properties, copper rods play an important role in many fields, including wire and cable, electrical and electronic equipment, machinery manufacturing, building decoration, and transportation. During the production of copper rods, when bending occurs, a drawing process is required to straighten the rod.

[0003] Chinese patent publication number CN217165899U discloses a drawing device for copper rod production, including a drawing mechanism comprising an L-shaped plate, an annular plate, an arc-shaped block, a rotating roller, and a first pressure roller; a first screw is rotatably connected to the inner right wall of the L-shaped plate. In this invention, a first motor drives a first bevel gear to rotate via a rotating rod, the first bevel gear drives a second screw to rotate via a second bevel gear, and the second screw moves the arc-shaped block via a moving rod to fix the copper rod. A first electric telescopic rod moves the first pressure roller downwards, and a second electric telescopic rod moves the second pressure roller upwards. The second motor, through the rotation of the first screw, moves the moving plate to the right, thereby causing the annular plate to move the copper rod to the right, achieving a straightening effect. This facilitates fixing and drawing copper rods of different thicknesses without requiring replacement with matching drawing equipment, thus making the copper rod drawing device highly practical and improving work efficiency.

[0004] Existing copper rod production drawing devices suffer from low efficiency due to drawing only one end of a single copper rod at a time, and the fact that the copper rod is only confined in the vertical direction during drawing, making it prone to lateral displacement and affecting the drawing effect. To overcome these disadvantages, this utility model provides a copper rod production drawing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a copper rod production drawing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a copper rod production drawing device, comprising a base plate, a vertical frame fixedly connected to the upper center of the base plate, a first sliding groove through one side of the vertical frame, connecting blocks symmetrically slidably connected to both ends of the first sliding groove, drawing frames fixedly connected to both ends of the connecting blocks, a top frame fixedly connected to the top center of the vertical frame, a second sliding groove on both sides of the top frame, clamping rods symmetrically slidably connected to both ends of the second sliding groove, a third sliding groove on one top end of the drawing frame, a first slider symmetrically slidably connected to both ends of the third sliding groove, a fourth sliding groove on one side wall end of the drawing frame, a second slider symmetrically slidably connected to both ends of the fourth sliding groove, a fixing frame fixedly connected to the ends of the first slider and the second slider, and several pressure rollers rotatably connected to the inner side of the fixing frame via a rotating shaft.

[0007] Furthermore, a first bidirectional screw is rotatably connected inside the first groove, and the two ends of the first bidirectional screw are respectively threaded to the corresponding connecting blocks. A first motor is fixedly connected to one side of the upright, and the output end of the first motor passes through the side wall of the upright and is fixedly connected to one end of the first bidirectional screw.

[0008] Furthermore, each of the second sliding grooves is rotatably connected to a second bidirectional screw, and both ends of the second bidirectional screw are threadedly connected to the corresponding clamping rods. The top side of the top frame is fixedly connected to a second motor at the position corresponding to the second bidirectional screw. The output end of the second motor passes through the side wall of the top frame and is fixedly connected to one end of the corresponding second bidirectional screw. Clamping blocks are fixedly connected to the opposite sides of the clamping rods.

[0009] Furthermore, a third bidirectional screw is rotatably connected inside the third slide groove. The two ends of the third bidirectional screw are respectively threaded to the corresponding first slider. A third motor is fixedly connected to one side of the pull frame at the position corresponding to the third bidirectional screw. The output end of the third motor passes through the side wall of the pull frame and is fixedly connected to one end of the third bidirectional screw.

[0010] Furthermore, a fourth bidirectional screw is rotatably connected inside the fourth slide groove. The two ends of the fourth bidirectional screw are respectively threaded to the corresponding second slider. A fourth motor is fixedly connected to one side of the pull frame at the position corresponding to the fourth bidirectional screw.

[0011] Furthermore, the pull frame has a square structure, and the two opposite fixing frames are both located at the center of the pull frame. The center of the pull frame is also located at the center between the two corresponding clamping rods.

[0012] The beneficial effects of this utility model are:

[0013] When in use, this copper rod production drawing device has the following advantages:

[0014] 1. In this solution, a base plate, a vertical frame, a first sliding groove, a first bidirectional screw, a connecting block, a top frame, a second sliding groove, a second bidirectional screw, clamping rods, clamping blocks, and a pulling frame are provided. The copper rod to be pulled is placed in the center between two corresponding clamping rods, with its two ends passing through the pulling frames on both sides. The second motor drives the second bidirectional screw to rotate, thereby causing the clamping rods and clamping blocks on the upper and lower sides to move towards each other to clamp the copper rod. After the copper rods to be straightened are placed on both sides of the vertical frame, the first motor drives the first bidirectional screw to rotate, thereby causing the connecting block and the corresponding pulling frame to move to both sides.

In this scheme, a third slide groove, a third bidirectional screw, a first slider, a fourth slide groove, a fourth bidirectional screw, a second slider, a fixing frame, and pressure rollers are provided. After the two ends of the copper rod pass through the drawing frames on both sides, the third motors corresponding to the drawing frames on both sides drive the corresponding third bidirectional screws to rotate, thereby causing the first sliders at both ends to move towards each other until the pressure rollers of the fixing frames at their ends abut against the outside of the copper rod. Similarly, the fourth motors corresponding to the drawing frames on both sides drive the corresponding fourth bidirectional screws to rotate, thereby causing the second sliders at both ends to move towards each other until the pressure rollers of the fixing frames at their ends abut against the outside of the copper rod. During drawing, the position of the copper rod is limited in both the horizontal and vertical directions to avoid deviation and affect the drawing effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, a copper rod production drawing device is disclosed, comprising a base plate 1, a vertical frame 2 fixedly connected to the upper center of the base plate 1, a first sliding groove 3 extending through one side of the vertical frame 2, connecting blocks 6 symmetrically slidingly connected to both ends of the first sliding groove 3, and drawing frames 13 fixedly connected to both ends of the connecting blocks 6, a top frame 7 fixedly connected to the top center of the vertical frame 2, a second sliding groove 8 on both sides of the top frame 7, clamping rods 10 symmetrically slidingly connected to both ends of the second sliding groove 8, a third sliding groove 14 at one top end of the drawing frame 13, a first slider 16 symmetrically slidingly connected to both ends of the third sliding groove 14, a fourth sliding groove 18 at one side wall end of the drawing frame 13, a second slider 20 symmetrically slidingly connected to both ends of the fourth sliding groove 18, a fixing frame 22 fixedly connected to the ends of the first slider 16 and the second slider 20, and several pressure rollers 23 rotatably connected to the inner side of the fixing frame 22 via a rotating shaft.

[0026] like Figure 1-5As shown, a first bidirectional screw 4 is rotatably connected inside the first slide groove 3. Both ends of the first bidirectional screw 4 are threadedly connected to corresponding connecting blocks 6. A first motor 5 is fixedly connected to one side of the upright frame 2. The output end of the first motor 5 passes through the side wall of the upright frame 2 and is fixedly connected to one end of the first bidirectional screw 4. The pulling frame 13 has a square structure. The two opposing fixed frames 22 correspond to the center position of the pulling frame 13. The center of the pulling frame 13 corresponds to the center between the two corresponding clamping rods 10. A second bidirectional screw 9 is rotatably connected inside the second slide groove 8. Both ends of the second bidirectional screw 9 are threadedly connected to the corresponding clamping rods 10. A second motor 12 is fixedly connected to the top side of the top frame 7 at the position corresponding to the second bidirectional screw 9. The output end of the second motor 12 passes through the side wall of the top frame 7 and is fixedly connected to the corresponding second bidirectional screw 6. One end of the screw 9 is fixedly connected, and clamping blocks 11 are fixedly connected to the opposite sides of the clamping rod 10. Each clamping block 11 has a V-shaped groove. The first motor 5 and the second motor 12 are electrically connected to an external power supply. The copper rod to be pulled is placed in the center between the two corresponding clamping rods 10, and its two ends pass through the pulling frames 13 on both sides. The second motor 12 is started, thereby driving the second bidirectional screw 9 to rotate, which in turn drives the clamping rods 10 and clamping blocks 11 on the upper and lower sides to move towards each other to clamp the copper rod. After the copper rods to be straightened are placed on both sides of the stand 2, the first motor 5 is started, thereby driving the first bidirectional screw 4 to rotate, which in turn drives the connecting block 6 and the corresponding pulling frame 13 to move to both sides along the direction of the first slide groove 3. The two ends of the two copper rods are pulled simultaneously by the four fixed frames 22 and the corresponding pressure rollers 23 to improve the pulling efficiency.

[0027] like Figure 1-5As shown, a third bidirectional screw 15 is rotatably connected inside the third slide groove 14. Both ends of the third bidirectional screw 15 are threadedly connected to the corresponding first slider 16. A third motor 17 is fixedly connected to one side of the pulling frame 13 at the position corresponding to the third bidirectional screw 15. The output end of the third motor 17 passes through the side wall of the pulling frame 13 and is fixedly connected to one end of the third bidirectional screw 15. A fourth bidirectional screw 19 is rotatably connected inside the fourth slide groove 18. Both ends of the fourth bidirectional screw 19 are threadedly connected to the corresponding second slider 20. A fourth motor 21 is fixedly connected to one side of the pulling frame 13 at the position corresponding to the fourth bidirectional screw 19. The output end of the fourth motor 21 passes through the side wall of the pulling frame 13 and is fixedly connected to the fourth bidirectional screw 16. One end of the screw 19 is fixedly connected. The third motor 17 and the fourth motor 21 are both electrically connected to an external power supply. The third motor 17 corresponding to the two pull-out frames 13 is started respectively, thereby driving the corresponding third bidirectional screw 15 to rotate. This causes the first sliders 16 at both ends to move towards each other until the pressure rollers 23 of their end fixing frames 22 abut against the outside of the copper rod. Similarly, the fourth motor 21 corresponding to the two pull-out frames 13 is started respectively, thereby driving the corresponding fourth bidirectional screw 19 to rotate. This causes the second sliders 20 at both ends to move towards each other until the pressure rollers 23 of their end fixing frames 22 abut against the outside of the copper rod. The position of the copper rod is limited in both the horizontal and vertical directions to avoid deviation and affect the pulling effect.

[0028] Working principle: In use, the copper rod to be pulled is placed in the center between the two corresponding clamping rods 10, with its two ends passing through the pulling frames 13 on both sides. The second motor 12 is started, which drives the second bidirectional screw 9 to rotate, thereby causing the clamping rods 10 and clamping blocks 11 on both sides to move towards each other to clamp the copper rod. At the same time, the third motors 17 corresponding to the two pulling frames 13 are started, which drive the corresponding third bidirectional screw 15 to rotate, thereby causing the first sliders 16 at both ends to move towards each other until the pressure rollers 23 of the end fixing frame 22 abut against the outside of the copper rod. Similarly, the fourth motors 21 corresponding to the two pulling frames 13 are started. This causes the corresponding fourth bidirectional screw 19 to rotate, which in turn causes the second sliders 20 at both ends to move towards each other until the pressure rollers 23 of the end fixing frame 22 abut against the outside of the copper rod. This limits the position of the copper rod in both the horizontal and vertical directions to prevent deviation and affect the pulling effect. After the copper rods to be straightened are placed on both sides of the stand 2, the first motor 5 is started, which drives the first bidirectional screw 4 to rotate, which in turn drives the connecting block 6 and the corresponding pulling frame 13 to move to both sides along the direction of the first slide groove 3. The four fixing frames 22 and the corresponding pressure rollers 23 are used to pull the two ends of the two copper rods at the same time to improve the pulling efficiency.

Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
