DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-11 The present invention provides a copper alloy wire continuous extrusion device, including a base 1, an extrusion mechanism 2 with a cylinder 24 is arranged on the top of the base 1, the cylinder 24 is fixedly installed on the top of the base 1, and a feeding cylinder 3 for feeding copper alloy raw materials is installed on the top of the cylinder 24.

[0023] Among them, the extrusion mechanism 2 includes a hydraulic cylinder 21, a piston 22, and a cylinder 24. When in use, the hydraulic cylinder 21 pushes the piston 22 to move, and the piston 22 extrude and mold the copper alloy raw material inside the cylinder 24; the copper alloy raw material is continuously fed into the cylinder 24 through the feed barrel 3. The design of the feed barrel 3 ensures that the raw material can smoothly enter the cylinder 24 without causing blockage or accumulation of raw materials.

[0024] In the technical solution of the embodiment of the present application, a buffer mechanism 5 with a first cone 54 is provided at the output end of the cylinder 24, and the first cone 54 is connected and installed at the output end of the cylinder 24. A spiral groove 55 for buffering the feed pressure of the copper alloy raw material is opened inside the first cone 54, and a spiral rotating rod assembly 56 with a spiral support 561 is provided inside the spiral groove 55. A first motor 51 is fixedly installed on the outer surface of the cylinder 24, and a first gear 52 is fixedly installed on the output shaft of the first motor 51. A second gear 53 is rotatably installed inside the cylinder 24, and the first gear 52 is meshed with the second gear 53. One end of the spiral support 561 is fixedly connected to one end of the second gear 53, and a spiral blade 562 for crushing lumps in the copper alloy raw material is installed on the outer surface of the spiral support 561.

[0025] Among them, the buffer mechanism 5 includes a first motor 51, a first gear 52, a second gear 53, a first cone 54, a spiral groove 55, and a spiral rotating rod assembly 56. When the raw material is extruded by the extrusion mechanism 2, it is first extruded into the inside of the first cone 54. At this time, the raw material on the edge can be spirally flowed through the spiral groove 55, and by starting the first motor 51, the first motor 51 drives the first gear 52 to rotate, the first gear 52 drives the second gear 53 to rotate, and the second gear 53 drives the spiral rotating rod to rotate. Among them, the spiral rotating rod assembly 56 includes a spiral support 561 and a spiral blade 562. At this time, the spiral support 561 is used to support the spiral blade 562, and the spiral blade 562 in the spiral rotating rod assembly 56 is used to buffer the feeding pressure of the copper alloy raw material. The design of the spiral groove 55 and the spiral blade 562 can guide the raw material to gradually disperse during the rotation process, and at the same time break up the lumps in the raw material to ensure the uniform distribution of the raw material.

[0026] In some embodiments, a circulation assembly 57 with an auger 573 is provided on the outer surface of the first conical cylinder 54, a long tube 574 is fixedly installed on the outer surface of the first conical cylinder 54, a first discharge pipe 571 for discharging is installed between the feed end of the long tube 574 and the spiral groove 55, a second discharge pipe 575 is installed between the discharge end of the long tube 574 and the cylinder 24, an auger 573 for conveying excess raw materials is rotatably installed inside the cylinder 24, a second motor 572 is fixedly installed at one end of the cylinder 24, and the output shaft of the second motor 572 is fixedly connected to the auger 573.

[0027] Among them, the circulation component 57 includes a first discharge pipe 571, a second motor 572, an auger 573, a long tube 574, and a second discharge pipe 575. When the spiral groove 55 is continuously fed, the raw material extruded in the spiral groove 55 can be discharged through the first discharge pipe 571, and re-introduced into the interior of the cylinder 24 through the second discharge pipe 575, so that the raw material can circulate. The design of the circulation flow allows excess or insufficiently extruded raw materials to be re-introduced into the cylinder 24 for recycling, which greatly improves the utilization rate of the raw materials and the uniformity of the quality of the extruded wire. At the same time, the auger 573 is driven to rotate by the second motor 572, so that the auger 573 can continuously mix the discharged raw materials, and can also avoid rapid condensation between the raw materials, thereby affecting the subsequent extrusion of the raw materials into wires, thereby ensuring stable output of the wires.

[0028] In some embodiments, a heat preservation mechanism 4 with a heating box 41 is provided at the top of the base 1, and the heating box 41 is fixedly installed at the top of the base 1. A heat conducting plate 42 for heating the raw materials inside the cylinder 24 to maintain a constant temperature is installed inside the cylinder 24. The spiral support 561 and the second gear 53 are both provided with cavities for heat storage to prevent the copper alloy raw materials from sticking. The output end of the heating box 41 is connected to the inner cavity of the heat conducting plate 42 and the inner cavity of the spiral support 561 through a heat pipe 43.

[0029] Among them, the heat preservation mechanism 4 includes a heating box 41, a heat conduction plate 42, and a heat conduction pipe 43. When the raw material is pretreated and formed, the heat flow is discharged through the heat conduction pipe 43 by the heating box 41, and is connected with the cavity inside the cylinder 24, the spiral support 561 and the second gear 53 through the heat conduction pipe 43, thereby realizing continuous heating and constant temperature control of the raw material, effectively preventing the cooling and condensation of the raw material during the extrusion process, avoiding the problem of wire bonding, and ensuring the continuity and stability of the extrusion process.

[0030] In some embodiments, a hydraulic cylinder 21 for extruding the copper alloy raw material is fixedly installed on the top of the base 1, a piston 22 is slidably installed inside the cylinder 24, the output shaft of the hydraulic cylinder 21 is fixedly connected to the piston 22, and a baffle 23 for sealing the feed barrel 3 is fixedly installed on the outer side of the piston 22, and the baffle 23 slides on the cylinder 24 close to the top wall of the feed barrel 3.

[0031] Among them, the extrusion mechanism 2 also includes a baffle 23. When the feed barrel 3 feeds the inside of the cylinder 24, the hydraulic cylinder 21 applies extrusion force to the raw material through the piston 22, which improves the flexibility of the extrusion process and can adjust the extrusion force according to production needs. The sliding sealing function of the baffle 23 on the top wall of the cylinder 24 ensures the sealing during the extrusion process, ensures the continuity and quality of the extruded wire, and prevents leakage of raw materials.

[0032] In some embodiments, a long plate 27 is fixedly installed inside the cylinder 24, and an arc-shaped groove 28 is opened at the top of the long plate 27. A conical rod 25 for stirring the copper alloy raw material inside the cylinder 24 is rotatably installed on the surface of the piston 22 close to the first conical cylinder 54, and a slider 26 is fixedly installed on one side of the conical rod 25, and the slider 26 slides inside the arc-shaped groove 28.

[0033] Among them, the extrusion mechanism 2 also includes a tapered rod 25, a slider 26, a long plate 27, and an arc-shaped slide groove 28. When the piston 22 moves, the tapered rod 25 will be pushed to move. Since the slider 26 at one end of the tapered rod 25 is slidably installed in the arc-shaped slide groove 28, the tapered rod 25 will reciprocate along the shape of the arc-shaped slide groove 28. The rotating tapered rod 25 can not only extrude the raw materials, but also vibrate and stir the raw materials, thereby ensuring that the gaps between the raw materials are reduced, increasing the dense effect of the raw material extrusion, and ensuring the quality of the wire.

[0034] In some embodiments, a spiral protrusion is disposed on the outer surface of the conical rod 25 , and the conical rod 25 is inserted into the interior of the first conical cylinder 54 .

[0035] The spiral protrusion can enhance the stirring effect of the cone rod 25 on the raw material.

[0036] In some embodiments, an exhaust mechanism 6 with a second cone 61 is provided at the output end of the first cone 54. The second cone 61 is connected and installed at the output end of the first cone 54. A plurality of annular tubes 63 are fixedly installed on the outer surface of the second cone 61. An exhaust main pipe 65 is connected and installed between the plurality of annular tubes 63. A bronchus 62 is connected and installed between the annular tubes 63 and the inner cavity of the second cone 61. A film 64 for air permeability is installed on the inner wall of the inner cavity of the second cone 61 near the bronchus 62.

[0037] Among them, the exhaust mechanism 6 includes a second cone 61, a bronchial tube 62, an annular tube 63, a film 64, and an exhaust main pipe 65. When the copper alloy raw material is extruded into the second cone 61, the film 64 on the outer surface of the second cone 61 can effectively discharge the bubbles generated during the extrusion process, thereby avoiding the influence of the bubbles on the quality of the wire. At the same time, multiple annular tubes 63 are connected to the inner cavity of the second cone 61 through the bronchial tube 62, so that the gas is discharged through the exhaust main pipe 65, thereby improving the physical quality and stability of the wire and ensuring the mechanical properties and service life of the wire.

[0038] In some embodiments, an auxiliary mechanism 8 with a smear block 82 is provided at the output end of the second cone 61, which is used to apply anti-friction on the surface of the extruded wire. The smear block 82 is installed at the wire output end of the second cone 61, and the top end of the smear block 82 is connected to a feed pipe 81.

[0039] Among them, the auxiliary mechanism 8 includes a feed pipe 81 and a smear block 82. The feed pipe 81 is responsible for providing the required anti-friction coating to the smear block 82. When the wire is output from the second cone 61, it will contact the smear block 82. At this time, the coating material provided by the feed pipe 81 will be evenly coated on the surface of the wire. This process is continuous, ensuring that the wire can be evenly coated over the entire length. The main effect of the smear block 82 is to reduce the friction of the wire during subsequent processing or transportation, which helps to protect the surface quality of the wire and prevent scratches, wear or deformation caused by friction.

[0040] In some embodiments, a limiting mechanism 7 with a rolling assembly 72 is provided at the output end of the second cone 61, a support seat 71 is fixedly installed on the top of the base 1, and a rolling assembly 72 for limiting the output wire is fixedly installed at the position of the support seat 71 near the output end of the second cone 61. The rolling assembly 72 includes a roller 722, and a support frame 721 is fixedly installed on one side of the support seat 71. Both rollers 722 are rotatably installed on the inner wall of the support frame 721, and the outer surface of the roller 722 is covered with a protective net 723 that increases friction.

[0041] Among them, the limiting mechanism 7 includes a support seat 71 and a rolling assembly 72, and the rolling assembly 72 includes a support frame 721, a roller 722, and a protective net 723. The support seat 71 is fixedly installed on the base 1, and the support frame 721 is installed on one side of the support seat 71 to provide stable support for the roller 722. The roller 722 rotates in the support frame 721. The two rollers 722 can achieve limited output of the wire. At the same time, the protective net 723 on the outer surface of the roller 722 increases the friction between the wire and the wire, ensuring the stable output of the wire, effectively protecting the integrity of the wire, and improving production efficiency and product quality.

[0042] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto.
