Description

Technical Field

[0001] The invention relates to the technical field of wire forming, and in particular to a combined alloy wire forming device. Background Art

[0002] The alloy wire combined forming device is a device used to process alloy materials into wires of specific shapes. It integrates multiple functional modules. Through coordinated cooperation, it can efficiently and accurately complete the transformation from raw materials to formed wires. It consists of a traction wheel and a drive motor. The various cross-sections formed by the alloy wires are usually formed by the cooperation of multiple structures, and the cross-sections of the alloy wires are usually circular cross-sections and flat cross-sections. The formation of alloy wires with these two cross-sections requires multiple different structures to cooperate with each other to be pressed and formed. However, the pressed and formed structures in the prior art cannot be switched quickly, that is, the same structure cannot achieve the effect of two pressed cross-sections. This also requires the operator to replace the corresponding wire pressing device. Such operation will undoubtedly increase the difficulty of operation and reduce production efficiency.

[0003] Therefore, we designed a combined alloy wire forming device. Summary of the invention

Such operation will undoubtedly increase the difficulty of operation and reduce production efficiency. A combined alloy wire forming device is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, a guide funnel for guiding the alloy wire is further provided in the wire drawing tube, and a drive ring connected to the toggle plate is further provided in the inner cavity.

[0008] Preferably, the first rolling wheel and the second rolling wheel press the alloy wire into flat wire and round wire.

[0009] Preferably, the pressing part further includes:

[0010] A rotating ring that rotates within the wire-drawing tube through a rotating cavity, and both the first rolling wheel and the second rolling wheel are connected to the rotating ring through a connecting support part;

[0011] A first shaft bracket and a second shaft bracket, and the first shaft bracket and the second shaft bracket are connected to the first rolling wheel and the second rolling wheel through rollers.

[0012] Preferably, the connecting support part includes a support plate. The first shaft bracket and the second shaft bracket are symmetrically arranged on both sides of the support plate respectively, and the support plate slides on the first shaft bracket and the second shaft bracket through a sliding groove. The support plate is connected to the rotating ring through a support rod, and a rotating threaded sleeve is sleeved on the support rod.

[0013] Preferably, a positioning plate is fixed on the support rod, a lifting plate is sleeved on the rotating threaded sleeve, a threaded groove adapted to the rotating threaded sleeve is coaxially provided on the lifting plate, the rotating threaded sleeve is rotatably connected to the rotating ring, and the rotating threaded sleeve abuts against the positioning plate. Side plates are provided on both sides of the lifting plate, and the first shaft bracket and the second shaft bracket are connected to the side plates on both sides of the lifting plate through rotating pins and connecting plates.

[0014] Preferably, an oil pipe penetrates through the positioning plate, and a first pressing piston connected to the lifting plate is arranged in the oil pipe. A rubber hose is arranged on the oil pipe, and the other end of the rubber hose is connected to the rotating ring.

[0015] Preferably, a main sliding hole is provided in the rotating ring, a side wall sliding hole perpendicular to and communicating with the main sliding hole is provided on the side wall of the main sliding hole, a first positioning rod and a second positioning rod are respectively provided on the main sliding hole and the side wall sliding hole, a second pressing piston slides on the main sliding hole, and a connecting rod is connected between the first positioning rod and the second pressing piston. The rubber hose communicates with the main sliding hole.

[0016] Preferably, rounded corners are respectively provided at the opposite ends of the first positioning rod and the second positioning rod.

[0017] Preferably, side grooves are circumferentially provided on the inner wall of the rotating cavity, a pressing plate slides in the side grooves, and the pressing plate slides telescopically in the side grooves through a return spring.

[0018] The beneficial effects of the present invention are:

[0019] The present invention adopts one end of the alloy wire to be wound on the wire-releasing roller, and the alloy wire is wound on the outer wall of the wire-drawing roller, so that the wire-drawing roller can reel in the alloy wire under the action of the external driving mechanism, thereby avoiding the conventional winding device. As the more wire is wound, the faster the corresponding winding line speed is, the faster the pulling speed of the alloy wire will be, which will undoubtedly affect the forming. The scheme adopted in the present application is a single-circle winding on the wire-drawing roller, and the continuous rotation of the wire-drawing roller will not cause the pulling line speed of the alloy wire wound on the wire-drawing roller, which will ensure that the speed of the pulled alloy wire is consistent, and can better provide a stable environment for the forming of the alloy wire.

[0020] The pressing plate of the present invention is telescopically slid in the side groove by the return spring. At this time, the second positioning rod, under the action of the return spring, pushes the second positioning rod toward the connecting rod with the pressing plate. When the rounded corner at the bottom of the second positioning rod presses against the main sliding hole, the pressing plate is flush with the end of the side groove. That is, in this state, the first positioning rod is extended, and the second positioning rod is retracted and no longer located in the side groove. Therefore, at this time, the driving ring presses the toggle plate against the first positioning rod and rotates with the rotating ring, that is, it will rotate and press the round wire.

[0021] When the rotating threaded sleeve flips in the opposite direction to move the lifting plate away from the positioning plate, the first pressing piston in the oil pipe will draw out the oil in the main sliding hole. At this time, the rounded corner at the bottom of the first positioning rod will squeeze the rounded corner of the second positioning rod, pushing the second positioning rod to move toward the side groove. When the rotating ring moves the second positioning rod to the position of the side groove, it will extend into the side groove. At the same time, the toggle plate no longer presses against the first positioning rod, thereby achieving the positioning of the rotating ring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] Reference Figures 1 - 11, An alloy wire combined forming device, including a wire drawing tube 1 and a wire winding box 2. The same alloy wire 5 passes through the wire drawing tube 1 and the wire winding box 2. An unwinding roller 3 is provided in the wire winding box 2, and a guiding funnel for guiding the alloy wire 5 is also provided in the wire drawing tube 1. In this way, the unwinding roller 3 in the wire winding box 2 can effectively unwind the wire. Since a wire drawing roller 4 is provided in the wire drawing tube 1, one end of the alloy wire 5 is wound around the unwinding roller 3, and the alloy wire 5 is wound around the outer side wall of the wire drawing roller 4. In this way, under the action of an external driving mechanism, the wire drawing roller 4 will wind up the alloy wire 5. In a conventional winding device, as more wire is wound, the corresponding winding linear speed becomes faster, so the pulling speed of the alloy wire 5 will be faster, which will undoubtedly affect the forming. However, in the solution of this application, the adopted solution is to wind the alloy wire 5 around the wire drawing roller 4 in a single layer. The continuous rotation of the wire drawing roller 4 will not cause the pulling linear speed of the alloy wire 5 wound around the wire drawing roller 4 to change. In this way, the pulling speed of the alloy wire 5 can be ensured to be consistent, providing a more stable environment for the forming of the alloy wire.

[0037] A plurality of pressing parts for pressing and forming the alloy wire 5 are also provided in the wire drawing tube 1. The pressing part includes a first rolling wheel 9 and a second rolling wheel 10. The alloy wire 5 is located between the first rolling wheel 9 and the second rolling wheel 10. Refer to Figure 5 and Figure 6 state. The first rolling wheel 9 and the second rolling wheel 10 press the alloy wire 5 into a flat wire 51 and a round wire 52.

[0038] The pressing part further includes a rotating ring 11. The rotating ring 11 rotates in the wire drawing tube 1 through a rotating cavity. The first rolling wheel 9 and the second rolling wheel 10 are both connected to the rotating ring 11 through a connecting support part. An inner cavity 6 is provided in the wire drawing tube 1, and a shifting plate 8 for pushing the pressing part to rotate is provided in the inner cavity 6. A driving ring 7 connected to the shifting plate 8 is also provided in the shifting plate 8. Therefore, the wire drawing roller 4 and the driving ring 7 are driven to rotate by an external driving device;

[0039] The connecting support part includes a support plate 14. The first shaft bracket 12 and the second shaft bracket 13 are symmetrically arranged on both sides of the support plate 14, and the support plate 14 slides on the first shaft bracket 12 and the second shaft bracket 13 through a chute. The first shaft bracket 12 and the second shaft bracket 13 are connected to the first rolling wheel 9 and the second rolling wheel 10 through rollers. Therefore, by changing the positions of the first shaft bracket 12 and the second shaft bracket 13 on both sides of the support plate 14, the positions of the first rolling wheel 9 and the second rolling wheel 10 can be changed.

[0040] Refer to Figure 7 state. This state is two states of the first rolling wheel 9 and the second rolling wheel 10, that is, two states of forming a flat wire 51 and a round wire 52 will be formed.

[0041] It should be noted that the flat wire 51 is formed by the first rolling wheel 9 and the second rolling wheel 10 rotating on the first axle support 12 and the second axle support 13, and the rotating ring 11 is in a limiting state. In this way, the alloy wire 5 will pass through the first rolling wheel 9 and the second rolling wheel 10, and finally the flat wire 51 is formed;

[0042] The formation of the round wire 52 will separate the first rolling wheel 9 and the second rolling wheel 10 on the first axle support 12 and the second axle support 13. At this time, the limiting state of the rotating ring 11 will also be released. At this time, the rotating ring 11 rotates, so that the first rolling wheel 9 and the second rolling wheel 10 will form a circular ring, that is, a cylindrical shape is formed for the alloy wire 5, and finally the round wire 52 is formed. Therefore, wires in two states can be formed.

[0043] The support plate 14 is connected to the rotating ring 11 through the support rod 15. A rotating threaded sleeve 16 is sleeved on the support rod 15. It should be noted that there is a peripheral motor on the rotating ring 11 that drives the rotating threaded sleeve 16 to rotate. Therefore, it will drive the rotating threaded sleeve 16 to rotate.

[0044] A positioning plate 18 is fixed on the support rod 15. A lifting plate 17 is sleeved on the rotating threaded sleeve 16. A threaded groove adapted to the rotating threaded sleeve 16 is coaxially provided on the lifting plate 17. The lifting plate 17 moves under the action of the rotating threaded sleeve 16 and moves towards the positioning plate 18. The setting of the positioning plate 18 is to prevent the continuous descent of the positioning plate 18. After abutting against the positioning plate 18, it will no longer move. At the same time, at this time, the first rolling wheel 9 and the second rolling wheel 10 are in a separated state, that is, the state of forming the round wire 52.

[0045] The rotating threaded sleeve 16 is rotatably connected to the rotating ring 11, and the rotating threaded sleeve 16 abuts against the positioning plate 18. Side plates 22 are provided on both sides of the lifting plate 17, and the first axle support 12 and the second axle support 13 are connected to the side plates 22 on both sides of the lifting plate 17 through rotating pins and connecting plates 23.

[0046] A oil pipe 19 penetrates through the positioning plate 18, and a first pressing piston 20 connected to the lifting plate 17 is provided in the oil pipe 19. A rubber hose 21 is provided on the oil pipe 19, and the other end of the rubber hose 21 is connected to the rotating ring 11. In this way, as the lifting plate 17 approaches the positioning plate 18, the first pressing piston 20 on the lifting plate 17 will extend into the oil pipe 19 and squeeze the oil liquid in the oil pipe 19 to enter the main sliding hole 26 in the rotating ring 11 through the rubber hose 21.

[0047] Refer to Figures 8 - 11In this state, a main sliding hole 26 is provided in the rotating ring 11, and side wall sliding holes which are vertically connected to each other are opened on the side wall of the main sliding hole 26. A first positioning rod 24 and a second positioning rod 25 are respectively provided on the main sliding hole 26 and the side wall sliding hole, and the first positioning rod 24 and the second positioning rod 25 are vertical to each other.

[0048] A second pressing piston 28 slides on the main sliding hole 26, and a connecting rod 27 is connected between the first positioning rod 24 and the second pressing piston 28. The rubber hose 21 is connected to the main sliding hole 26. When oil enters the main sliding hole 26, it pushes the second pressing piston 28 to move.

[0049] The opposite ends of the first positioning rod 24 and the second positioning rod 25 are respectively provided with chamfered corners. It should be noted that, under the action of the return spring 31, the second positioning rod 25 pushes the second positioning rod 25 to move and squeeze in the direction of the first positioning rod 24. When the second positioning rod 25 presses against the outer wall of the first positioning rod 24, the return spring 31 is in a force storage state. When the oil enters the main sliding hole 26, the second pressing piston 28 pushes the first positioning rod 24 to move with the connecting rod 27.

[0050] The inner wall of the rotating cavity is provided with a side groove 29 in a circumferential shape, and a pressing plate 30 slides in the side groove 29, and the pressing plate 30 is telescopically slid in the side groove 29 by the return spring 31. At this time, the second positioning rod 25, under the action of the return spring 31, drives the pressing plate 30 to push the second positioning rod 25 toward the connecting rod 27. When the rounded corner at the bottom of the second positioning rod 25 presses against the main sliding hole 26, the pressing plate 30 is flush with the end of the side groove 29, that is, in this state, the first positioning rod 24 is extended, and the second positioning rod 25 is retracted and no longer located in the side groove 29. Therefore, at this time, the driving ring 7 drives the toggle plate 8 to press against the first positioning rod 24 and drives the rotating ring 11 to rotate, that is, at this time, it will rotate and press the round wire 52;

[0051] On the contrary, when the rotating threaded sleeve 16 is flipped in the opposite direction, the lifting plate 17 moves away from the positioning plate 18, and the first pressing piston 20 in the oil pipe 19 will draw out the oil in the main sliding hole 26. At this time, the rounded corners at the bottom of the first positioning rod 24 will squeeze the rounded corners of the second positioning rod 25, and will push the second positioning rod 25 to move toward the side groove 29. When the rotating ring 11 moves the second positioning rod 25 to the side groove 29, it will extend into the side groove 29. At the same time, the toggle plate 8 no longer presses against the first positioning rod 24, and the positioning of the rotating ring 11 is achieved.

[0052] Furthermore, by adjusting the positions of the first rolling wheel 9 and the second rolling wheel 10, the formation of the flat wire 51 is achieved. The first rolling wheel 9 and the second rolling wheel 10 rotate on the first shaft bracket 12 and the second shaft bracket 13, and the rotating ring 11 is in a limiting state. In this way, the alloy wire 5 will pass through the first rolling wheel 9 and the second rolling wheel 10, and finally the flat wire 51 is formed.

[0053] The formation of the round wire 52 will cause the first rolling wheel 9 and the second rolling wheel 10 on the first shaft bracket 12 and the second shaft bracket 13 to separate from each other. At the same time, the limiting state of the rotating ring 11 will also be released. At this time, the rotating ring 11 rotates, so that the first rolling wheel 9 and the second rolling wheel 10 will form a circular ring, that is, the alloy wire 5 is formed into a cylindrical shape, and finally the round wire 52 is formed. Therefore, wires in two states can be formed.

[0054] The working principle of the present invention is as follows:

[0055] A guiding funnel for guiding the alloy wire 5 is also provided in the wire drawing tube 1, so that the wire discharging roller 3 in the wire winding box 2 can effectively discharge the wire. Since the wire drawing roller 4 is provided in the wire drawing tube 1, one end of the alloy wire 5 is wound around the wire discharging roller 3, and the alloy wire 5 is wound around the outer side wall of the wire drawing roller 4. In this way, under the action of an external driving mechanism, the wire drawing roller 4 will wind up the alloy wire 5. In a conventional winding device, as more wire is wound, the corresponding winding linear speed will be faster, so the pulling speed of the alloy wire 5 will be faster, which will undoubtedly affect the forming. In the solution adopted in this application, the alloy wire 5 is wound around the wire drawing roller 4 in a single loop. The continuous rotation of the wire drawing roller 4 will not cause the pulling linear speed of the alloy wire 5 wound around the wire drawing roller 4, so that the pulling speed of the alloy wire 5 can be ensured to be consistent, and a stable environment can be better provided for the forming of the alloy wire.

[0056] Then, a thread groove adapted to the rotating thread sleeve 16 is coaxially provided on the lifting disc 17. The lifting disc 17 moves under the action of the rotating thread sleeve 16 and moves towards the positioning plate 18. The setting of the positioning plate 18 is to prevent the continuous descent of the positioning plate 18. After abutting against the positioning plate 18, it will no longer move. At the same time, at this time, the first rolling wheel 9 and the second rolling wheel 10 are in a separated state, that is, in the state of forming the round wire 52. As the lifting disc 17 approaches the positioning plate 18, the first pressing piston 20 on the lifting disc 17 will extend into the oil pipe 19 and squeeze the oil liquid in the oil pipe 19 to enter the main sliding hole 26 in the rotating ring 11 through the rubber hose 21.

[0057] By adjusting the positions of the first rolling wheel 9 and the second rolling wheel 10, the formation of the flat wire 51 is achieved. The first rolling wheel 9 and the second rolling wheel 10 rotate on the first shaft bracket 12 and the second shaft bracket 13, and the rotating ring 11 is in a limiting state. In this way, the alloy wire 5 will pass through the first rolling wheel 9 and the second rolling wheel 10, and finally the flat wire 51 is formed.

[0058] The formation of the round wire 52 will cause the first rolling wheel 9 and the second rolling wheel 10 on the first shaft bracket 12 and the second shaft bracket 13 to separate from each other. At this time, the limiting state of the rotating ring 11 is also released. The rotating ring 11 rotates at this time, so that the first rolling wheel 9 and the second rolling wheel 10 form a circular ring, that is, the alloy wire 5 is formed into a cylindrical shape, and finally the round wire 52 is formed. Therefore, wires in two states can be formed.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
