Description

Technical Field

[0001] This utility model relates to waste electromechanical recycling technology, and in particular to a device for dismantling copper wires from waste motor rotors. Background Technology

[0002] In the scrap motor recycling industry, stator copper wire recycling is one of the most valuable stages. Traditional methods of dismantling stator windings are extremely primitive and inefficient. They typically involve using tools such as hammers, chisels, and levers, relying on manual hammering and prying to remove the copper wire windings piece by piece from the stator insulation slots. This method has the following serious drawbacks: 1. Extremely labor-intensive and inefficient, entirely dependent on manual labor; dismantling a single stator is time-consuming and costly; 2. Significant safety hazards; during hammering and prying, broken copper wires and flying tools can easily injure operators; 3. Severe damage to the copper wires; violent dismantling causes the copper wires to break, flatten, shorten, and deteriorate, directly reducing their recycling value. Summary of the Invention

[0003] In view of the above situation, this utility model provides a device for dismantling copper wires of waste motor stators, which improves the labor efficiency of dismantling waste motors, prevents damage to copper wires caused by violent dismantling, and achieves efficient and safe dismantling of waste motor stators.

[0004] The purpose of this utility model is achieved as follows: A device for dismantling copper wire from a waste motor stator includes a base, a square base plate connected to the top of the base, fixed length support rods vertically fixed at the four corners of the base plate, the top of the fixed length support rods connected by a crossbeam, a horizontal support rod connected in the middle of the fixed length support rods between the crossbeam and the base plate, a pad plate provided on the top of the crossbeam, a through hole provided in the middle of the pad plate, bearing seats fixed on both sides of the through hole of the pad plate by bolts, an electro-hydraulic push rod vertically installed between the bearing seats, the lower end of the electro-hydraulic push rod connected to the upper end of a steel wire rope through the through hole in the middle of the pad plate, and a clamp connected to the lower end of the steel wire rope; a through hole provided in the middle of the base plate, an outwardly extending slot provided on the outer periphery of the through hole, a positioning block installed in the slot, a threaded fixed length support rod installed on the positioning block, a locking hook fitted on the fixed length support rod, and an adjusting nut installed on the locking hook.

[0005] Furthermore, a "7"-shaped latch is provided on one side of the locking hook.

[0006] Furthermore, the upper section of the fixed-length support rod is provided with an external thread that matches the adjusting nut.

[0007] Furthermore, the positioning block is in the shape of an "I" and the groove matches the card slot.

[0008] Compared with existing technologies, this invention significantly improves work efficiency and is applicable to the disassembly of motor stators of different models and specifications. It can smoothly and vertically pull out the windings without breaking or deforming the copper wires, maximizing the preservation of wire length and integrity. The structure is simple, easy to manufacture, and has low production costs, making it highly practical. Attached Figure Description

[0011] The following structural drawings and embodiments further illustrate this utility model. See also Figures 1 to 6 A device for dismantling copper wire from waste motor stators includes a base 1, a square base plate 2 connected to the top of the base 1, and fixed length support rods 3 vertically fixed at the four corners of the base plate 2. The upper section of the fixed length support rods 3 has external threads matching adjusting nuts 14. The top of the fixed length support rods 3 is connected via a crossbeam. A horizontal support rod 7 is connected to the middle section of the fixed length support rods 3 between the crossbeam and the base plate 2. A pad 9 is provided on the top of the crossbeam. A through hole is provided in the middle of the pad 9. Bearing seats 11 are fixed to both sides of the through hole of the pad 9 by bolts 10. An electro-hydraulic actuator 12 (model: DYTP15000-1300 / 35) is vertically installed between the two bearing seats 11. The lower end of the electro-hydraulic actuator 12 is connected to the upper end of a steel wire rope 8 through the through hole in the middle of the pad 9. A clamp 6 (such as...) is connected to the lower end of the steel wire rope 8. Figures 1 to 5(As shown); A through hole is provided in the middle of the base plate 2, and an outwardly extending slot 16 is provided on the outer periphery of the through hole. An I-shaped positioning block 13 is installed in the slot 16. The groove of the positioning block 13 matches the slot 16. A threaded length support rod 3 is installed on the positioning block 13. A locking hook 15 is fitted on the length support rod 3. A 7-shaped hook is provided on one side of the locking hook 15. An adjusting nut 14 is installed on the top of the locking hook 15 (e.g. Figure 6 (As shown).

[0012] In manufacturing this utility model, a simple frame is first constructed from a base 1, a base plate 2, a fixed-length support rod 3, a horizontal support rod 7, and a pad 9. Three slots 16, equally spaced outwards from the center, are cut into the base plate 2. Figure 3 As shown), so that the positioning block 13 can move equidistantly around the center, the electro-hydraulic actuator 12 is fixed to the frame pad 9 by the bearing seat 11 and bolts 10 (as shown). Figure 5 As shown), the electro-hydraulic actuator 12 is connected to the clamp 6 via the wire rope 8 to form a pulling mechanism. Three adjusting screws 4, a positioning block 13, an adjusting nut 14, and a locking hook 15 form a stator fixing mechanism. The motor stator 5 is securely fixed via the adjusting nut 14 and the locking hook 15 (as shown). Figure 6 As shown, the electro-hydraulic actuator 12 is pulled out by the telescopic control clamp 6, and the copper wire in the motor stator 5 is pulled out by manual operation of the clamp 6.

[0013] Example: A company, regarding the copper wire dismantling device for waste motor rotors according to this utility model, first determines the length and width dimensions of the base plate 2 and the height of the adjusting screw 4 based on the external dimensions of the largest and smallest motors to be dismantled. The base plate 2 needs to have a slot 16 cut out so that the positioning block 13 can move within it (e.g., ...). Figure 3As shown), a simplified frame is constructed based on existing sheet metal and steel. For example, the base 1 can be spliced ​​and welded using 12# channel steel; the fixed-length support rod 3, the horizontal support rod 7, and the crossbeam 17 can be spliced ​​and welded using rectangular tubes 100*100*8. By calculating the force and stroke required for the disassembly device, the electro-hydraulic push rod 12 model is selected as DYTP15000-1300 / 35. It is connected to the toothed clamp 6 purchased online via steel wire rope 8 to form a pulling mechanism. The pulling mechanism is fixed to the frame pad 9 via bearing seat 11 and bolts 10. The stator fixing mechanism consists of three adjusting screws 4, positioning blocks 13, adjusting nuts 14, and locking hooks 15. The positioning blocks 13 can be adjusted on the frame base plate 2. The adjusting screws 4 are welded to the positioning blocks 13. The locking hooks 15 can be adjusted up and down by the adjusting screws 4 and then fixed by the adjusting nuts 14. The locking mechanism 15 is constructed using steel plates and steel pipes to achieve the dimensions shown in the figure. One end of the motor stator 5 is wound with a cutting machine and cut open. The locking hook 15 is then fixed to the motor stator 5 by adjusting the position of the positioning block 13. The adjusting nut 14 is used to tighten the screw, ensuring that the motor stator remains stationary during the wire pulling process. Finally, the electro-hydraulic push rod 12 is manually operated to use the clamps 6 to clamp the copper wire of the motor stator 5 and pull it upwards. After the wire pulling is completed, the motor stator 5 with the wire removed can be removed by loosening the adjusting nut 14 and removing the positioning block 13, and replaced with other motor stators 5 that need to be disassembled.

[0014] This invention reduces the traditional manual disassembly time of several hours to a mechanical extraction and disassembly time of a few minutes, greatly improving efficiency. By adjusting the stator fixing mechanism, it can be applied to motor stators of different models and specifications. This device has a reasonable structure, is easy to operate, and can significantly improve disassembly efficiency and copper wire recovery rate.
