Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a quick clamping device for a silver alloy wire drawing machine. Background Art

[0002] Wire drawing machine is a processing equipment that can draw thick wire into thin wire of different wire diameters according to the requirements. The general structure of wire drawing machine includes wire pay-off wheel, wire take-up wheel and wire drawing die. The wire drawing die is arranged between the wire pay-off wheel and the wire take-up wheel. Figure 1 The raw wire is arranged on the pay-off wheel, and one end of the raw wire passes through the wire drawing die and is fixed on the take-up wheel. As the take-up wheel rotates, the finished wire after drawing is gradually wound on the take-up wheel.

[0003] In order to ensure the stability of the winding of the take-up wheel, one end of the wire needs to be fixed on the take-up wheel, and a wire clamping device is used for fixing. The conventional wire clamping device has poor flexibility in use, and includes a first part and a second part. The first part is connected to any one of the four support rods on the take-up wheel through a traction iron chain. A conical hole is provided on the first part, and the end of the wire is passed through the conical hole, and the second part is embedded in the conical hole. When the take-up wheel is winding the wire, a wedge-shaped clamp is formed between the first part and the second part, thereby fixing the end of the wire. Figure 2 shown.

[0004] The above-mentioned wire clamping devices are usually operated with both hands. In order to ensure the stability of the wire clamping work, it often takes a lot of time to clamp and fix one end of the wire, which makes the wire fixing work more troublesome and less safe. For example, patent publication number CN206305211U discloses a wire drawing machine head clamping puller clamp, which simplifies the original clamping into a single clamping piece, changes the original clamping between two clamps into clamping between the clamping piece and the base, thereby achieving the fixation of the wire end. Summary of the invention

[0005] In order to solve the problem that the conventional wedge-shaped clamping device is complicated to operate and use, the utility model provides a quick clamping device for a silver alloy wire drawing machine, which adopts an eccentric clamping structure to clamp and fix the wire end, and the entire clamping operation is convenient and quick.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A quick clamping device for a silver alloy wire drawing machine is connected to a support rod of a take-up wheel through a traction iron chain and can move with the take-up wheel, comprising a clamping seat, a clamping plate and an ear plate, wherein the outer surface of the clamping seat is in an arc shape and matches the contour of the take-up wheel, the inner surface of the clamping seat is an inclined surface, and the inner surface of the clamping seat and the surface where the tangent of the take-up wheel is located form an angle of 15-30°;

[0008] The card board is arranged above the card seat. The card board includes an integrally formed eccentric wheel section and a pressing section. The eccentric wheel section is rotatably arranged on the card seat, and there is an adjustable clamping gap between the eccentric wheel section and the inner surface of the card seat, which is convenient for clamping wire rods with different wire diameters. The pressing section is arranged above the eccentric wheel section, and the pressing section extends upward and protrudes out of the card seat, which is convenient for rotating the eccentric wheel section. One end of the card seat is provided with the ear plate with a hole, which is convenient for hooking the traction iron chain.

[0009] Further, the card seat is a block made of stainless steel. The card seat includes a pressing block and a baffle. The baffles are respectively screwed to both sides of the pressing block, which facilitates the disassembly and assembly of the baffle. The baffle extends upward and protrudes from the pressing block. After the pressing block and the two baffles are connected and combined, the cross section is in a "U" shape.

[0010] Further, the outer surface of the pressing block is in an inward concave circular arc shape and the inner surface is an inclined surface. The ear plate is arranged at one end of the pressing block. The ear plate is connected to the support rod through a traction iron chain. The card board is arranged above the other end of the pressing block.

[0011] Further, the card board is arranged between the two baffles. A cylindrical pin is arranged on each baffle. The two cylindrical pins are respectively inserted through the two end parts of the eccentric wheel section. The eccentric wheel section is convenient for rotating around the cylindrical pin. The eccentric wheel section is a shaft body with a certain length; the pressing section is a plate structure, and the pressing section is tangent to the eccentric wheel section. The pressing section extends upward and protrudes from the baffle, which facilitates the operation of the pressing section.

[0012] Further, there is the clamping gap between the eccentric wheel section and the inner surface of the pressing block. A rack structure is arranged on the circumferential side wall of the eccentric wheel section to form a continuous uneven tooth surface. The tooth surface faces the inner surface of the pressing block, which increases the friction force with the end of the wire rod and ensures the firm fixation of the wire rod end.

[0013] By the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] The structure of the present utility model is reasonably designed. The quick clamping device and the wire take-up wheel are connected by a traction iron chain, so that the quick clamping device can operate together with the wire take-up wheel. The outer surface of the card seat in the quick clamping device is in a circular arc shape, which can fit the contour of the wire take-up wheel, be better arranged on the wire take-up wheel, reduce the damage of the card seat to the wire take-up wheel, and at the same time reduce the up and down movement of the card seat on the wire take-up wheel to prevent the friction between the wire rod and the wire take-up wheel and cause scratches on the product surface.

[0015] The inner surface of the clamping seat of the utility model is an inclined surface, which can avoid large bending of the wire when it is connected and transitioned between the clamping seat and the take-up wheel, avoid the risk of wire breakage, and reduce the danger during the drawing process. The clamping seat is connected with a clamping plate, which is an eccentric wheel structure. There is a clamping gap between the clamping plate and the clamping seat. The size of the clamping gap is adjustable, and wires of different wire diameters can be clamped. At the same time, the clamping plate has a toothed surface, which can effectively improve the reliability of clamping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0023] like Figure 3~Figure 5 As shown, a quick clamping device for a silver alloy wire drawing machine is connected to the support rod 7 of the take-up wheel 2 through a traction iron chain 6, and can be driven to rotate as the take-up wheel 2 runs, such as Figure 3 The quick clamping device includes a clamping seat 8, a clamping plate 9 and an ear plate 10. The clamping plate 9 and the ear plate 10 are arranged on the clamping seat 8 to form a movable whole, which is used to clamp the wire end. Figure 4 shown.

[0024] The holder 8 is a block made of stainless steel, and the outer surface of the holder 8 is arc-shaped and matches the contour of the take-up wheel 2, so that it can fit the take-up wheel 2 well. The inner surface of the holder 8 is an inclined surface, and the inner surface of the holder 8 and the surface where the tangent of the take-up wheel 2 is located are at an angle of 15-30 degrees, which facilitates the wire to be wound on the take-up wheel 2 and avoids large bends.

[0025] In this embodiment, the card seat 8 includes a pressing block 81 and a baffle 82. The outer surface of the pressing block 81 is concave in an arc shape, and the inner surface is an inclined surface. The baffle 82 is screwed to both sides of the pressing block 81 respectively to realize the disassembly and assembly of the baffle 82. The baffle 82 extends upward and protrudes from the pressing block 81. Therefore, the cross-section of the combination of the pressing block 81 and the two baffles 82 is in a "U" shape.

[0026] A clamping plate 9 is arranged above the card seat 8. The clamping plate 9 is arranged between the two baffles 82. The clamping plate 9 and the card seat 8 are used together to clamp the end of the wire. The clamping plate 9 includes an integrally formed eccentric wheel section 91 and a pressing section 92. The eccentric wheel section 91 is a shaft body with a certain length. The eccentric wheel section 91 is rotatably arranged on the card seat 8. To realize the rotation of the eccentric wheel section 91, a cylindrical pin 11 is arranged on each baffle 82. The two cylindrical pins 11 are respectively inserted through the two end parts of the eccentric wheel section 91. Therefore, the whole clamping plate 9 can rotate.

[0027] Since the clamping plate 9 can rotate, there is a clamping gap 12 with adjustable size between the eccentric wheel section 91 and the inner surface of the card seat 8, that is, there is a clamping gap 12 between the eccentric wheel section 91 and the inner surface of the pressing block 81. The end of the wire is inserted into the clamping gap 12 and clamped, realizing the connection and fixation between the wire and the quick clamping device.

[0028] To facilitate the operation of rotating the clamping plate 9, a pressing section 92 is arranged above the eccentric wheel section 91. The pressing section 92 is of a plate structure. The pressing section 92 is tangent to the eccentric wheel section 91. The pressing section 92 extends upward and protrudes from the card seat 8, that is, the pressing section 92 extends upward and protrudes from the baffle 82. Therefore, by operating the pressing section 92, the eccentric wheel section 91 can be flipped to realize the rotation control of the whole clamping plate 9.

[0029] To realize the connection between the quick clamping device and the wire take-up wheel 2, an ear plate 10 with a hole is arranged at one end of the card seat 8. Specifically, the ear plate 10 is arranged at one end of the pressing block 81. The ear plate 10 is connected to the support rod 7 through a traction iron chain 6. The clamping plate 9 is arranged above the other end of the pressing block 81. That is, the ear plate 10 and the clamping plate 9 are arranged at both ends of the card seat 8.

[0030] The principle of the present utility model is as follows: One end of the traction iron chain 6 is hooked on the ear plate 10 to connect the quick clamping device, and the other end of the traction iron chain 6 is hooked on the support rod 7 to connect the wire take-up wheel 2. Therefore, the wire take-up wheel 2 and the quick clamping device are connected, and the wire take-up wheel 2 can drive the quick clamping device to operate together. The end of the wire passes through the wire drawing die and is inserted into the clamping gap 12. The clamping plate 9 is manually pressed to rotate, so that the clamping gap 12 gradually shrinks. The end of the wire is clamped and fixed by the eccentric wheel section 91 and the pressing block 81. Along with the operation of the wire take-up wheel 2, the wire is gradually wound up to realize the wire drawing operation of the wire.

[0031] In order to optimize the product structure and achieve the reliability of clamping, a rack structure is provided on the peripheral wall of the eccentric wheel segment 91 to form a continuous uneven tooth surface 13, and the tooth surface 13 faces the inner surface of the pressing block 81, such as Figure 5 Under the action of the tooth surface 13, the friction between the eccentric wheel segment 91 and the wire is increased to prevent the wire end from being loosened.

[0032] The utility model controls the rotation of the clamping plate 9, and the clamping plate 9 cooperates with the clamping seat 8 to lock or unlock the wire end, thereby realizing the rapid clamping of the wire in the silver alloy wire drawing process, improving production efficiency, and reducing the safety risk of personnel operation. At the same time, by adjusting the size of the clamping gap 12 between the clamping plate 9 and the clamping seat 8, the clamping requirements of wires of different wire diameters are met, and the clamping can be operated with one hand, solving the problem of poor flexibility in the use of conventional wire clamping devices.

[0033] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
