Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, specifically a precision nickel-titanium alloy wire drawing machine. Background Technology

[0002] Precision nickel-titanium alloy wire drawing machines are high-precision equipment designed specifically for processing nickel-titanium shape memory alloy wires. They are designed to achieve high-precision wire drawing while maintaining the material's superelasticity and shape memory function. Through multi-stage drawing dies, the original nickel-titanium alloy billet is gradually reduced in diameter to stretch into micron-level fine wires. They are also compatible with irregularly shaped dies to produce special cross-section wires for use in medical devices and electronic components.

[0003] Most existing precision nickel-titanium alloy wire drawing machines use a fixed pressure roller to press down on the nickel-titanium alloy wire to eliminate curling stress during wire drawing. However, the pressure roller is usually locked with bolts, which makes it cumbersome to adjust the pressure roller when needed. Moreover, repeated tightening of the bolts can easily lead to wire slippage, affecting the adjustment and use of the pressure roller of the precision nickel-titanium alloy wire drawing machine.

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a precision nickel-titanium alloy wire drawing machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision nickel-titanium alloy wire drawing machine, comprising a drawing machine body, a controller, a guide drawing frame, a tension roller, and a take-up roller.

[0006] As described above, a controller is provided at the top of the wire drawing machine body, a guide wire drawing frame is provided at the top of the wire drawing machine body near the controller, a tension roller is provided on one side of the guide wire drawing frame, a take-up roller is provided on the side of the tension roller away from the guide wire drawing frame, a pressing adjustment mechanism extending to the outside is provided inside the tension roller, the pressing adjustment mechanism includes a fixed seat provided at the bottom of the tension roller, a rotating wheel is provided on one side of the fixed seat, and a rotating rod extending into the fixed seat is provided on one side of the rotating wheel.

[0008] As described above, a bevel gear set is connected between the threaded rod and the rotating rod, and a guide rod extending into the tension roller is provided at the top of the fixed seat. The guide rods are symmetrically distributed at the top of the fixed seat.

[0009] As described above, an auxiliary cooling mechanism is provided between the guide wire drawing frame and the tension roller.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-3 As shown, this utility model provides a technical solution: a precision nickel-titanium alloy wire drawing machine, including a drawing machine body 1, a controller 2, a guide drawing frame 3, a tension roller 4, and a take-up roller 5.

[0025] like Figure 1 As shown, a controller 2 is provided at the top of the wire drawing machine body 1. A guide wire drawing frame 3 is provided at the top of the wire drawing machine body 1 near the controller 2. A tension roller 4 is provided on one side of the guide wire drawing frame 3. A take-up roller 5 is provided on the side of the tension roller 4 away from the guide wire drawing frame 3. A pressing adjustment mechanism 6 extending to the outside is provided inside the tension roller 4. The pressing adjustment mechanism 6 includes a fixed seat 601 provided at the bottom of the tension roller 4. A rotating wheel 602 is provided on one side of the fixed seat 601. A rotating rod 603 extending into the fixed seat 601 is provided on one side of the rotating wheel 602.

[0026] By activating the controller 2, the guide wire drawing frame 3 can guide the nickel-titanium alloy wire, and then the tension roller 4 and the take-up roller 5 can rotate, thereby enabling the processing of the nickel-titanium alloy wire and realizing the wire drawing operation. Then, the rotating wheel 602 is rotated to drive the rotating rod 603 to rotate.

[0027] like Figure 3 As shown, a threaded rod 604 extending outward is provided inside the fixed base 601 on the side near the rotating rod 603. One end of the threaded rod 604 extends into the tension roller 4. A bevel gear set 605 is connected between the threaded rod 604 and the rotating rod 603. A guide rod 606 extending into the tension roller 4 is provided at the top of the fixed base 601. The guide rods 606 are symmetrically distributed at the top of the fixed base 601.

[0028] The rotating rod 603 can drive the bevel gear set 605 to rotate, and the rotation of the bevel gear set 605 can drive the threaded rod 604 to rotate, thereby driving the tension roller 4 to move up and down. At the same time, the guide rod 606 can guide the tension roller 4.

[0029] like Figures 1-3 As shown, by activating the controller 2, the guide wire drawing frame 3 guides the nickel-titanium alloy wire, and then the tension roller 4 and the take-up roller 5 rotate, thereby processing the nickel-titanium alloy wire and realizing the wire drawing operation. Then, by rotating the rotating wheel 602, the rotating wheel 602 drives the rotating rod 603 to rotate, which in turn drives the bevel gear set 605 to rotate. At the same time, the bevel gear set 605 drives the threaded rod 604 to rotate, which in turn drives the tension roller 4 to move up and down. The tension roller 4 can also move on the surface of the guide rod 606, making the movement of the tension roller 4 more stable. This allows the tension roller 4 to tighten the loose nickel-titanium alloy wire during movement, and it can be quickly moved and adjusted, avoiding damage to the bolts caused by repeated tightening. At the same time, the tension roller 4 can be adjusted without removing it for reinstallation, making it more convenient to adjust its position.

[0030] like Figure 4 As shown, an auxiliary cooling mechanism 7 is provided between the guide wire drawing frame 3 and the tension roller 4. The auxiliary cooling mechanism 7 includes a fixing frame 701 provided between the guide wire drawing frame 3 and the tension roller 4, and a water pump 702 is provided inside the fixing frame 701.

[0031] By activating the water pump 702, water can be extracted from inside the fixed frame 701.

[0032] like Figure 5As shown, a mounting bracket 703 is provided at the top of the fixed frame 701, and a motor 704 is installed at the top of the mounting bracket 703. The output end of the motor 704 is connected to a first rotating rod 705 through a coupling. A second rotating rod 706 extending into the fixed frame 701 is provided on one side of the first rotating rod 705. A gear set body 707 is connected between the second rotating rod 706 and the first rotating rod 705. A connecting block 708 is connected to the bottom end of the second rotating rod 706. A symmetrically distributed connecting rod 709 is provided at both ends of the connecting block 708. A uniformly distributed nozzle 710 is provided at the bottom end of the connecting rod 709.

[0033] The output of motor 704 can drive the first rotating rod 705 to rotate, and the rotation of the first rotating rod 705 can drive the gear set body 707 to rotate, so that the rotation of the gear set body 707 can drive the second rotating rod 706 to rotate. At the same time, when the second rotating rod 706 rotates, it can drive the connecting block 708, the connecting rod 709 and the nozzle 710 to rotate.

[0034] like Figure 4 As shown, a connector 711 is provided inside the second rotating rod 706, and a connecting pipe 712 is provided at the top of the connector 711. One end of the connecting pipe 712 is connected to the water pump 702.

[0035] By activating the water pump 702, water inside the fixed frame 701 is drawn into the connecting pipe 712, and then into the second rotating rod 706 and sprayed out through the nozzle 710, thereby avoiding high heat caused by friction during the wire drawing process of the precision nickel-titanium alloy wire drawing machine.

[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, by starting the motor 704, the output end of the motor 704 drives the first rotating rod 705 to rotate. When the first rotating rod 705 rotates, it drives the gear set body 707 to rotate. Simultaneously, when the gear set body 707 rotates, it drives the second rotating rod 706 to rotate. When the second rotating rod 706 rotates, it drives the connecting block 708 at the bottom to rotate. When the connecting block 708 rotates, it drives the connecting rod 709 to rotate. And when the connecting rod 709 rotates, it drives the nozzle 71. Rotate 0, then start the water pump 702, which can draw water from inside the fixed frame 701, allowing the water to be drawn into the connecting pipe 712 and then into the second rotating rod 706, so that the water can be sprayed out through the nozzle 710. The nozzle 710 has a water flow channel connected to the water supply channel, so that the precision nickel-titanium alloy wire drawing machine can cool down the heat generated during the wire drawing process through the water sprayed out by the nozzle 710. At the same time, the cooling effect is further improved by spraying out the recycled water flow.

[0037] Working principle: After pre-treating the surface of the nickel-titanium alloy wire, the wire is passed through the guide wire drawing frame 3, allowing it to be drawn through the drawing holes on the frame 3. The wire moves to one side, reaching the surface of the tension roller 4, where it is pressed down. The wire continues to move to one side, winding around the surface of the take-up roller 5, thus processing the wire and achieving the wire drawing operation. Then, by rotating the rotating wheel 6... 02 can drive the rotating rod 603, bevel gear set 605 and threaded rod 604 to rotate, so that when the threaded rod 604 rotates, it can drive the tension roller 4 to move up and down, and the tension roller 4 can move on the surface of the guide rod 606, so that the tension roller 4 can be more stable when moving, thus enabling the tension roller 4 to tighten the loose nickel-titanium alloy wire when moving, and the tension roller 4 can be moved and adjusted quickly, avoiding damage to the bolts caused by repeated tightening. At the same time, the tension roller 4 can be adjusted without removing it for installation, making it more convenient to adjust its position.
