Description

Technical Field

[0001] The present invention belongs to the technical field of wire cutting, and particularly relates to an alloy fine wire cutting device. Background Art

[0002] Copper alloy fine wire is an alloy material formed with copper as the matrix by adding elements such as chromium, cadmium, nickel, and gold, and is made through high-precision processing. Copper alloy fine wire is widely used in the field of precision manufacturing where parameters such as length, end face perpendicularity, and surface quality have extremely high requirements. Therefore, a cutting device can meet the above basic needs.

[0003] When the existing cutting device cuts alloy fine wire, the outlet adopts an open suspended structure design. After the wire extends a certain distance, a cutting knife is used to cut the wire.

[0004] When the above cutting device is used to cut alloy fine wire, it causes elastic deformation of the extended section of the wire due to insufficient bending stiffness caused by its own weight, resulting in the straightness of the cut wire not meeting the requirements of precision manufacturing. Also, during the cutting process, the wire will move or shift due to the force, which will lead to inaccurate cutting positions, thus causing problems such as a decline in cutting accuracy and product quality. Therefore, the present invention provides an alloy fine wire cutting device. Summary of the Invention

[0016] The beneficial effects of the present invention are as follows: 1. For an alloy fine wire cutting device of the present invention, by providing clamping plates, when an alloy fine wire needs to be cut, the moving plate drives the upper cutter to descend, and at the same time, the moving plate drives the limiting plate to descend. The limiting plate drives the tooth groove to descend and cooperate with the first gear, so that the first gear drives the rotating plate to rotate. The rotating plate drives the clamping plates to rotate, and the clamping plates can support the surface of the alloy fine wire extending from the discharging end, avoiding the alloy fine wire from being bent and displaced due to gravity, resulting in a curved cut after the alloy fine wire is cut, thus causing a deviation between the actual cutting length of the alloy fine wire and the designed size, and affecting the subsequent processing or assembly accuracy.

[0017] 2. For an alloy fine wire cutting device of the present invention, by providing a rack and a second gear, after the alloy fine wire is supported, the limiting plate drives the convex block on one side thereof to move, and the convex block presses the rack, so that the rack meshes with one of the second gears, causing a single second gear to rotate. The second gear meshes with another second gear, causing the two second gears to rotate simultaneously. The second gear drives the clamping plates to rotate, and the clamping plates can clamp and fix the alloy fine wire, avoiding the axial displacement of the alloy fine wire before cutting, resulting in inconsistent cutting dimensions, and thus increasing the scrap rate of the alloy fine wire.

[0018] 3. For an alloy fine wire cutting device of the present invention, by providing a limiting rod and a limiting hole, after the alloy fine wire is cut and falls between the clamping plates, then the rotating plate rotates and resets, causing the rotating plate to drive the clamping plates to be in an inclined state. Subsequently, the alloy fine wire can be discharged by gravity between the clamping plates. During the discharging process, the limiting rod enters the limiting hole to limit the rack, avoiding the rack moving and driving the clamping plates to rotate, resulting in the clamping plates clamping and fixing the alloy fine wire to be discharged, making it difficult for the alloy to be discharged, and affecting the subsequent support and fixing operation of the cut alloy fine wire, thereby reducing the cutting efficiency of the alloy fine wire.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Embodiment 1: As Figures 1 to 10As shown in the figure, an alloy fine wire cutting device according to an embodiment of the present invention includes a fixed frame 1, on which a plurality of positioning wheels 2 are rotatably arranged. An alloy fine wire 6 is arranged between the plurality of positioning wheels 2. A conveying component 3, a cutting component 4 and a supporting component 5 are arranged on the fixed frame 1. The supporting component 5 fixes and supports the alloy fine wire 6, and the cutting component 4 cuts the alloy fine wire 6; the cutting component 4 includes a moving plate 43 slidably connected to the fixed frame 1. A top cutter 44 is fixedly connected below the moving plate 43. A driving component 45 is also arranged below the moving plate 43. The supporting component 5 includes a supporting plate 51 fixedly connected to the fixed frame 1. A top cutter 44 is fixedly connected to the supporting plate 51. A rotating plate 53 is rotatably connected to the supporting plate 51. A clamping plate 55 is rotatably connected to the rotating plate 53; the moving plate 43 drives the driving component 45 to descend, drives the rotating plate 53 and the clamping plate 55 to rotate through the driving component 45 to support the alloy fine wire 6, and then drives the clamping plate 55 to rotate through the driving component 45 again to fix the alloy fine wire 6.

[0023] As Figure 4 , Figure 9 and Figure 10 shown, the driving component 45 includes a limiting plate 451 fixedly connected to the lower surface of the moving plate 43. The limiting plate 451 is provided with a plurality of tooth grooves 452. A first gear 52 is fixedly connected to the rotating end of the rotating plate 53. The first gear 52 includes a limiting tooth 521. A plurality of rotating teeth 522 are arranged on one side of the limiting tooth 521. The tooth grooves 452 and the rotating teeth 522 are meshed with each other. One side of the limiting tooth 521 and one side of the limiting plate 451 are in mutual contact.

[0024] As Figure 7 , Figure 8 and Figure 10 shown, a convex block 453 is arranged on one side of the tooth groove 452. The convex block 453 is fixedly connected to the limiting plate 451. A rack 54 is slidably connected inside the rotating plate 53. Second gears 551 are fixedly connected to the rotating ends of the clamping plates 55. One of the second gears 551 is meshed with the rack 54. The two second gears 551 are meshed with each other.

[0025] As Figure 8 shown, a first spring 532 is fixedly connected between the rack 54 and the rotating plate 53. One end of the rack 54 is arc-shaped.

[0026] As Figure 2 shown, a spring telescopic rod 56 is arranged between the rotating plate 53 and the supporting plate 51. The fixed end of the spring telescopic rod 56 is rotatably connected to the supporting plate 51. The telescopic end of the spring telescopic rod 56 is rotatably connected to the rotating plate 53.

[0027] Specifically, the alloy fine wire 6 is widely used in the field of precision manufacturing where extremely high requirements are placed on parameters such as length, end face perpendicularity, and surface quality. Therefore, a cutting device can meet the above basic requirements; When the existing cutting device cuts the alloy fine wire 6, the discharge port is designed with an open suspended structure, resulting in elastic deformation of the extended section of the wire due to insufficient bending stiffness caused by its own weight. This causes the straightness of the cut wire to fail to meet the requirements of precision manufacturing. At the same time, the elastic deformation will make the contact state between the cutting tool and the wire unstable, leading to defects such as burrs and chamfer collapse on the cutting surface. This not only affects the appearance quality of the wire but may also reduce its mechanical properties, such as tensile strength and fatigue life. In addition, during the cutting process, the wire will move or shift due to the applied force, resulting in inaccurate cutting positions, thereby causing problems of reduced cutting accuracy and product quality.

[0028] To solve the above problems, the present device is used as follows: In the initial state, the rotating plate 53 is inclined. At this time, the moving plate 43 can be driven to descend. The moving plate 43 drives the upper cutting tool 44 and the driving component 45 to descend. The limiting plate 451 in the driving component 45 descends synchronously with the moving plate 43. The limiting plate 451 drives the tooth groove 452 to descend. The tooth groove 452 descends and contacts the first gear 52. The tooth groove 452 pushes the limiting tooth 521 on the first gear 52 to move, causing the first gear 52 to rotate. The rotating tooth 522 on the first gear 52 meshes with the tooth groove 452, and the limiting tooth 521 releases the limit with the limiting plate 451. The first gear 52 drives the rotating plate 53 to rotate synchronously and stretches the spring telescopic rod 56. The rotating plate 53 drives the clamping plate 55 to rotate synchronously, causing the clamping plate 55 to rotate from an inclined state to a horizontal state. Subsequently, the alloy fine wire 6 passes through the positioning wheel 2 and moves through the conveying component 3 to the inclined surface between the lower cutting tool 57 and the clamping plate 55, and the clamping plate 55 can support the alloy fine wire 6; Subsequently, the limiting plate 451 continues to descend, causing the limiting tooth 521 to fit against one side of the limiting plate 451 and cooperate with the limiting plate 451 to limit the first gear 52. At the same time, the convex block 453 contacts the rack 54. The inclined surface of the convex block 453 presses the rack 54, causing the rack 54 to press the first spring 532 and slide on the fixed rod 531. The rack 54 slides and meshes with one of the second gears 551, causing one of the second gears 551 to rotate. The two second gears 551 mesh with each other, so that the two second gears 551 can be driven to rotate synchronously. The two second gears 551 rotate the clamping plate 55 towards the surface of the alloy fine wire 6 at the center, and the two clamping plates 55 can clamp and fix the alloy fine wire 6 therebetween; Finally, the upper cutting knife 44 descends. When the upper cutting knife 44 and the lower cutting knife 57 intersect, the alloy fine wire 6 can be cut. After cutting is completed, the rotating plate 53 resets. The spring telescopic rod 56 drives the rotating plate 53 to reset. The rotating plate 53 drives the clamping plate 55 to become inclined. Subsequently, the cut alloy fine wire 6 can slide downward by gravity for discharging operation. By arranging the clamping plate 55 in this device, the clamping plate 55 can support the surface of the alloy fine wire 6 extending from the discharging end, avoiding the alloy fine wire 6 from being bent and displaced due to gravity, resulting in a curved cut after cutting the alloy fine wire 6, thus causing a deviation between the actual cutting length of the alloy fine wire 6 and the designed dimension, affecting the subsequent processing or assembly accuracy. At the same time, it also avoids the axial displacement of the alloy fine wire 6 before cutting, resulting in inconsistent cutting dimensions, thereby increasing the scrap rate of the alloy fine wire 6.

[0029] As Figure 1 and Figure 2 As shown, the conveying component 3 includes a first motor 31 fixedly connected to the back of the fixed frame 1. The output end of the first motor 31 is fixedly connected with a driving wheel 32. A driven wheel 33 is arranged on one side of the driving wheel 32. The driven wheel 33 is rotatably connected inside the fixed frame 1.

[0030] Specifically, when it is necessary to convey the alloy fine wire 6, the first motor 31 can be turned on. The first motor 31 drives the driving wheel 32 to rotate. The driving wheel 32 and the driven wheel 33 are tangent and drive the driven wheel 33 to rotate synchronously, so that the alloy fine wire 6 between the driving wheel 32 and the driven wheel 33 is conveyed to the upper cutting knife 44 and the lower cutting knife 57 for cutting treatment.

[0031] As Figures 2 to 3 As shown, the cutting component 4 further includes a second motor 41 fixedly connected to one side of the fixed frame 1. The output end of the second motor 41 is fixedly connected with a lead screw 42. The lead screw 42 is rotatably connected to the back of the fixed frame 1. The lead screw 42 is threadedly connected with the inside of the moving plate 43.

[0032] Specifically, when it is necessary to drive the moving plate 43 to move, the second motor 41 can be turned on to work. The second motor 41 drives the lead screw 42 to rotate synchronously. The lead screw 42 is threadedly connected with the moving plate 43, so that the moving plate 43 slides inside the fixed plate, and the moving plate 43 can drive the upper cutting knife 44 to descend.

[0033] Embodiment 2: As Figure 8 and Figure 10As shown in the figure, a groove 541 is provided inside the rack 54. A magnetic block 454 is provided on one side of the bump 453. The magnetic block 454 is fixedly connected to the surface of the limit plate 451. The sizes of the magnetic block 454 and the groove 541 match each other. A magnetic wedge 533 is slidably connected inside the rotating plate 53. The magnetic wedge 533 and the rotating plate 53 are fixedly connected by a second spring 534. The magnetism of the magnetic wedge 533 and the magnetism of the magnetic block 454 repel each other. A limit rod 535 is provided on one side of the magnetic block 454. The limit rod 535 is slidably connected to one side of the rotating plate 53. One end of the limit rod 535 is in contact with the surface of the magnetic wedge 533. A limit hole 542 is provided below the rack 54. The size of the limit hole 542 matches the size of the limit rod 535.

[0034] Specifically, when the above-mentioned clamping plate 55 rotates to an inclined state and vibrates due to external factors during a collision, the rack 54 moves. The rack 54 moves and meshes with the second gear 551, causing the second gear 551 to rotate and drive the clamping plate 55 to rotate. The clamping plate 55 clamps the alloy fine wire 6 between them, resulting in a decrease in the blanking rate and thus a reduction in the cutting efficiency.

[0035] To avoid the above problems, the present device is used as follows: When the limit plate 451 follows the moving plate 43 downwards and the rotating plate 53 changes from an inclined state to a horizontal state, at this time, one end of the rack 54 is in contact with one side of the limit plate 451. The moving plate 43 continues to descend and drives the magnetic block 454 to descend synchronously. The magnetic block 454 contacts the magnetic wedge 533 and generates magnetic repulsion, causing the magnetic wedge 533 to compress the second spring 534 and slide towards the inside of the rotating plate 53. At this time, the limit rod 535 slides down along the inclined surface of the magnetic wedge 533, causing the limit rod 535 to disengage from the limit hole 542, thus releasing the limit on the rack 54. The moving plate 43 continues to descend, causing the bump 453 to squeeze the rack 54, causing the clamping plate 55 to rotate to fix the alloy fine wire 6. After use, the rack 54 is disengaged from the extrusion of the bump 453, and the magnetic wedge 533 is disengaged from the magnetic repulsion force of the magnetic block 454, causing the second spring 534 to drive the magnetic wedge 533 to reset. The magnetic wedge 533 pushes the limit rod 535 into the limit hole 542, thereby limiting the rack 54 and further avoiding the movement of the rack 54.

[0036] By limiting the rack 54, the present device can prevent the rack 54 from moving and driving the clamping plate 55 to rotate, resulting in the clamping plate 55 clamping and fixing the alloy fine wire 6 to be discharged, making it difficult to discharge the alloy and affecting the subsequent support and fixing operation of the alloy fine wire 6 after cutting, thereby reducing the cutting efficiency of the alloy fine wire 6.

[0037] Working principle: Turn on the second motor 41 to work. The second motor 41 drives the lead screw 42 to rotate synchronously. The lead screw 42 is threadedly connected to the moving plate 43, so that the moving plate 43 slides inside the fixed plate. The moving plate 43 can drive the upper cutter 44 to descend. The moving plate 43 drives the upper cutter 44 and the limiting plate 451 to descend synchronously. The limiting plate 451 drives the tooth groove 452 to descend. The tooth groove 452 descends and contacts the first gear 52. The tooth groove 452 pushes the limiting tooth 521 on the first gear 52 to move, so that the first gear 52 rotates. The rotating tooth 522 on the first gear 52 meshes with the tooth groove 452, and the limiting tooth 521 releases the limit with the limiting plate 451. The first gear 52 drives the rotating plate 53 to rotate synchronously and stretch the spring telescopic rod 56. The rotating plate 53 drives the clamping plate 55 to rotate synchronously, so that the clamping plate 55 rotates from an inclined state to a horizontal state. Subsequently, the alloy fine wire 6 passes through the positioning wheel 2 and between the driving wheel 32 and the driven wheel 33. Turn on the first motor 31. The first motor 31 drives the driving wheel 32 to rotate. The driving wheel 32 is tangent to the driven wheel 33 and drives the driven wheel 33 to rotate synchronously, so that the alloy fine wire 6 moves to the clamping plate 55 for support operation; Subsequently, the limiting plate 451 continues to descend, so that the limiting tooth 521 fits against one side of the limiting plate 451 and cooperates with the limiting plate 451 to limit the first gear 52. At this time, one end of the rack 54 fits against one side of the limiting plate 451. The moving plate 43 continues to descend and drives the magnetic block 454 to descend synchronously. The magnetic block 454 contacts the magnetic wedge block 533 and generates magnetic repulsion, so that the magnetic wedge block 533 squeezes the second spring 534 and slides toward the inside of the rotating plate 53. At this time, the limiting rod 535 slides downward along the inclined surface of the magnetic wedge block 533, so that the limiting rod 535 disengages from the limiting hole 542, and the limit on the rack 54 can be released. The moving plate 43 continues to descend. Subsequently, the convex block 453 contacts the rack 54. The inclined surface of the convex block 453 squeezes the rack 54, so that the rack 54 squeezes the first spring 532 and slides on the fixed rod 531. The rack 54 slides and meshes with one of the second gears 551, so that one of the second gears 551 rotates. The two second gears 551 mesh with each other, so as to drive the two second gears 551 to rotate synchronously. The two second gears 551 can rotate the clamping plate 55 toward the surface of the alloy fine wire 6 at the center. The two clamping plates 55 can clamp and fix the alloy fine wire 6 between them; Finally, the upper cutter 44 descends. The upper cutter 44 and the lower cutter 57 intersect to cut the alloy fine wire 6. After cutting is completed, the rotating plate 53 resets. The spring telescopic rod 56 drives the rotating plate 53 to reset. The rotating plate 53 drives the clamping plate 55 to become inclined. At this time, the magnetic wedge block 533 pushes the limiting rod 535 into the limiting hole 542 to limit the rack 54. Subsequently, the cut alloy fine wire 6 can slide downward by gravity for discharging operation.
