Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example:

[0028] like Figure 1 and Figure 2As shown, this embodiment of the invention provides a dual-station copper rod high-efficiency lubrication drawing device, including a base 1. One end of the base 1 is provided with a first copper rod inlet 2 and a first copper rod outlet 3. The end of the base 1 away from the first copper rod inlet 2 and the first copper rod outlet 3 is provided with a second copper rod outlet 4 and a second copper rod inlet 5. A groove 6 is provided between the first copper rod outlet 3 and the second copper rod inlet 5. A drawing mechanism 7 is provided in the groove 6. A self-lubricating device 8 is provided between the drawing mechanism 7 and the second copper rod inlet 5 and the first copper rod inlet 2, respectively. A guide groove 9 is provided at the ends of the first copper rod outlet 3 and the second copper rod outlet 4 that are far apart from each other.

[0029] like Figures 3 to 5 As shown, the pulling mechanism 7 includes a movable base 701. A protective shell 702 is provided at the end of the movable base 701 away from the base 1. A first through groove 703 and a second through groove 704 are respectively provided at the end of the protective shell 702 near the movable base 701. A first groove 705 and a second groove 706 are respectively provided inside the end of the movable base 701 near the first through groove 703 and the second through groove 704. A first clamping mechanism 707 and a second clamping mechanism 708 are respectively provided in the first groove 705 and the second groove 706.

[0030] The protective shell 702 is provided with a driver 709 at the end away from the movable base 701. The driver 709 is provided with a first sprocket 7010 at the end away from the second groove 706. The first sprocket 7010 is provided with a second sprocket 7011 at the end near the movable base 701. The surface of the second sprocket 7011 is provided with a chain 7012. The second sprocket 7011 is provided with a rotating column 7013 at the end near the protective shell 702. The rotating column 7013 is provided with a first thread 7014 and a second thread 7015 at the end surface of the rotating column 7013 located in the first groove 705. The rotating column 7013 is provided with a third thread 7016 and a fourth thread 7017 at the end surface of the rotating column 7013 located in the second groove 706.

[0031] With the above technical solution, when it is necessary to use the drawing mechanism 7 to draw copper rods, firstly, different copper rods are passed through the first through groove 703 and the second through groove 704. Then, the first sprocket 7010 is rotated by the driver 709. The first sprocket 7010 drives the second sprocket 7011 to rotate through the chain 7012. The second sprocket 7011 drives the rotating column 7013 to rotate. The rotating column 7013 uses the first thread 7014 and the second thread 7015 to put the first clamping mechanism 707 into a clamping state, clamping the copper rod. At this time, the rotating column 7013 uses the third thread 7016 and the fourth thread 7017, which are opposite to the thread direction of the first thread 7014 and the second thread 7015, to put the second clamping mechanism 708 into a loosening state. Then, the movable base 701 moves away from the first copper rod inlet 2 via the slide 6. The first clamping mechanism 707 moves with the movable base 701 and pulls the copper rod in the first through groove 703. After the pulling is completed, the driver 709 causes the first sprocket 7010 to rotate in the opposite direction, causing the rotating column 7013 to rotate in the opposite direction. At this time, the first clamping mechanism 707 releases the clamp on the copper rod, while the second clamping mechanism 708 enters the clamping state and clamps the copper rod in the second through groove 704. Then, the movable base 701 moves towards the first copper rod inlet 2 via the slide 6 and returns to its original position. Then, the second clamping mechanism 708 pulls the copper rod in the second through groove 704. Then, the above steps are repeated.

[0032] like Figure 6 and Figure 7 As shown, the first clamping mechanism 707 includes a mechanism base 70701. A plurality of movable plates 70702 are provided at one end of the mechanism base 70701 near the movable base 701. Clamping blocks 70703 are respectively provided on the surface of the two movable plates 70702 that are close to each other.

[0033] The movable plate 70702 is provided with a plurality of guide grooves 70704 at one end near the base 70701. A guide slider 70705 is provided in the guide groove 70704. A plurality of guide holes 70706 are provided between the guide groove 70704 and the clamping block 70703. A guide column 70707 is provided in the guide hole 70706. A threaded hole 70708 is provided between two guide holes 70706.

[0034] With the above technical solution, when it is necessary to clamp the copper rod, the two moving plates 70702 are gradually brought closer together by the cooperation of the rotating column 7013 and the threaded hole 70708. The clamping block 70703 moves with the moving plate 70702, thereby fixing the copper rod. The guide slider 70705 and the guide column 70707 are responsible for fixing the direction of one end of the moving plate 70702 when it moves. When it is necessary to release the clamping of the copper rod, the two moving plates 70702 are gradually moved away from each other by the cooperation of the rotating column 7013 and the threaded hole 70708.

[0035] Working principle:

[0036] This invention first involves passing different copper rods through a first copper rod inlet 2 and a second copper rod inlet 5, respectively. Then, each copper rod is passed through a different self-lubricating device 8. The annular self-lubricating device 8 provides comprehensive lubrication to the surface of the copper rod. Next, the copper rod passing through the first copper rod inlet 2 is placed into a drawing mechanism 7. The drawing mechanism 7 is then activated to clamp and fix the copper rod passing through the first copper rod inlet 2. The drawing mechanism 7 then moves towards the second copper rod outlet 4 to draw the copper rod passing through the first copper rod inlet 2. Finally, the drawn copper rod is passed through the second copper rod outlet 4 and cut off at the second copper rod outlet 4. The cut copper rod is moved to the designated position using the guide chute 9. At this time, the copper rod passing through the second copper rod inlet 5 will enter the drawing mechanism 7. Then, the drawing mechanism 7 releases the fixation of the copper rod passing through the first copper rod inlet 2 and clamps and fixes the copper rod passing through the second copper rod inlet 5. Then, the drawing mechanism 7 moves towards the direction of the first copper rod outlet 3, so that the drawing mechanism 7 returns to its original position. At the same time, the copper rod passing through the second copper rod inlet 5 is drawn. Then, the copper rod passing through the second copper rod inlet 5 is cut off using the first copper rod outlet 3. Then, the above steps are repeated, so that multiple copper rods can be drawn in one drawing cycle of the drawing mechanism 7, thereby improving the drawing efficiency.

[0037] When the copper rod needs to be drawn using the drawing mechanism 7, the copper rods are first passed through the first through slot 703 and the second through slot 704. Then, the first sprocket 7010 is rotated by the driver 709. The first sprocket 7010 drives the second sprocket 7011 to rotate via the chain 7012. The second sprocket 7011 drives the rotating column 7013 to rotate. The rotating column 7013 uses the first thread 7014 and the second thread 7015 to put the first clamping mechanism 707 into a clamping state, clamping the copper rod. At this time, the rotating column 7013 uses the third thread 7016 and the fourth thread 7017, which are opposite in direction to the first thread 7014 and the second thread 7015, to put the second clamping mechanism 708 into a loosening state. The movable base 701 moves away from the first copper rod inlet 2 via the slide 6. The first clamping mechanism 707 moves with the movable base 701 and pulls the copper rod in the first through groove 703. After the pulling is completed, the driver 709 causes the first sprocket 7010 to rotate in the opposite direction, causing the rotating column 7013 to rotate in the opposite direction. At this time, the first clamping mechanism 707 releases the clamp on the copper rod, while the second clamping mechanism 708 enters the clamping state and clamps the copper rod in the second through groove 704. Then the movable base 701 moves towards the first copper rod inlet 2 via the slide 6 and returns to its original position. Then the second clamping mechanism 708 pulls the copper rod in the second through groove 704. The above steps are then repeated.

[0038] When the copper rod needs to be clamped, the two moving plates 70702 gradually move closer to each other by the cooperation of the rotating column 7013 and the threaded hole 70708. The clamping block 70703 moves with the moving plate 70702, thereby fixing the copper rod. The guide slider 70705 and the guide column 70707 are responsible for fixing the direction of one end of the moving plate 70702 when it moves. When it is necessary to release the clamping of the copper rod, the two moving plates 70702 gradually move away from each other by the cooperation of the rotating column 7013 and the threaded hole 70708.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
