Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1-3 As shown, the tension controllable wire drawing machine of this utility model includes a frame 1, a tension adjustment component 2 and an air pump 6. The tension adjustment component 2 is disposed at one end of the top of the frame 1, and a drive motor 3 is installed at the other end of the top of the frame 1. A winding wheel 4 for drawing and winding the wire is installed on the drive end of the drive motor 3.
[0024] The tension adjustment assembly 2 includes a first mounting plate 21, a second mounting plate 22, a first slider 23, and a second slider 24. The first mounting plate 21 and the second mounting plate 22 are each provided with a sliding groove 25. The first slider 23 and the second slider 24 are slidably connected to the sliding grooves 25 on the first mounting plate 21 and the second mounting plate 22, respectively.
[0025] This utility model also includes wheel sets on both the first slider 23 and the second slider 24. Each wheel set includes support plates 28 arranged symmetrically on the upper and lower sides. The support plates 28 are fixedly connected to the corresponding first slider 23 and second slider 24. Guide wheels 210 are respectively provided at both ends of the support plates 28. A tension sensor 29 is installed on the support plate 28 on the first slider 23. The guide wheels 210 on the first slider 23 are installed on the tension sensor 29. The guide wheels 210 on the second slider 24 are rotatably connected to the support plate 28 on the second slider 24 through bearings.
[0026] In use, the assembly consisting of frame 1, tension adjustment component 2, wheel set and air pump 6 provides a tension-controllable wire drawing machine for wire drawing and winding operations. It can also provide cleaning components for the wheels and rollers that must be passed through before wire drawing and winding, so as to reduce the adhesion of wire debris to the wheels and rollers during the drawing process, reduce the wear of wire debris on the wheels and rollers, and reduce the scratches on the wire surface by wire debris, thereby improving the service life of the equipment and the product quality of the wire.
[0027] The present invention also includes guide rollers 211 for guiding and limiting the top and bottom of the wires, respectively, on the first slider 23 and the second slider 24 near the wire outlet of the guide wheel 210, which are rotatably mounted by bearings.
[0028] In use, the guide wheel 210 is used to guide and constrain the wire laterally, and the guide roller 211 is used to guide and constrain the wire vertically.
[0029] The present invention also includes a metal shaping hose 61 installed on one side of the first slider 23 and the second slider 24. The exhaust end of the metal shaping hose 61 is equipped with a nozzle 62 for blowing air onto the surface of the guide wheel 210 and the guide roller 211. The air pump 6 is disposed on the first mounting plate 21. The exhaust end of the air pump 6 is connected to the air inlet end of the metal shaping hose 61 through an air pipe.
[0030] In use, the cleaning assembly consists of an air pump 6, a metal shaping hose 61, and a nozzle 62. The air pump 6 supplies air to the metal shaping hose 61, which is then blown away by the nozzle 62. The nozzle 62 sprays air towards the guide wheel 210 and guide roller 211 at the corresponding positions, so that the residual shavings on the guide wheel 210 and guide roller 211 can be blown away.
[0031] The present invention also includes a lead screw 26 disposed in the slide groove 25 via a bearing, the bottom of the first slider 23 and the second slider 24 being threadedly sleeved with the lead screw 26 at the corresponding positions, and a servo motor 27 being mounted at the ends of the first mounting plate 21 and the second mounting plate 22, the drive end of the servo motor 27 being connected to the rotation shaft of the lead screw 26 at the corresponding position.
[0032] The lead screw 26, which is threaded onto the second slider 24, is a reciprocating lead screw.
[0033] In use, the servo motor 27 can be driven to rotate, so that the first slider 23 and the second slider 24, which are threadedly connected to the corresponding lead screw 26, can move on the slide groove 25.
[0034] This utility model also includes a PLC controller 5 installed at one end of the frame 1, the output end of the tension sensor 29 being electrically connected to the input end of the PLC controller 5 via a wire, and the output end of the PLC controller 5 being electrically connected to the input ends of the drive motor 3 and the servo motor 27 via a wire.
[0035] The tension of the guide wheel 210 on the first mounting plate 21 is detected by the tension sensor 29. When the tension of the guide wheel 210 exceeds the set value, the PLC controller 5 controls the servo motor 27 on the first mounting plate 21 to drive the corresponding lead screw 26 to rotate, so that the first slider 23 drives the guide wheel 210 and guide roller 211 above to move, so that the tension of the thread passing through the guide wheel 210 and guide roller 211 is adjusted to be close to the set value, ensuring the stability of the thread during the pulling and winding process.
[0036] In use, this utility model assembles the discharge end of the wire drawing equipment, which is used to wind the wire during drawing and provides a certain drawing force to achieve wire drawing and winding. The power supply unit in the work area provides power to the electrical components of this application. During use, the wire is passed between the guide wheel 210 and guide roller 211 on the first slider 23 and the second slider 24. The guide wheel 210 provides lateral guidance and constraint to the wire, and the guide roller 211 provides vertical guidance and constraint to the wire. The wire is then wound onto the winding wheel 4, and the drive motor 3 drives the winding wheel 4 to rotate, achieving wire winding. During this process, the servo motor 27 on the second mounting plate 22 drives the corresponding lead screw 26 to rotate. The reciprocating characteristic of this lead screw allows the second slider 24 to move reciprocally, thus allowing the wire to be wound back and forth on the winding wheel. During the process, the tension of the guide wheel 210 on the first mounting plate 21 is detected by the tension sensor 29. When the tension of the guide wheel 210 exceeds the set value, the PLC controller 5 controls the servo motor 27 on the first mounting plate 21 to drive the corresponding lead screw 26 to rotate, so that the first slider 23 drives the guide wheel 210 and guide roller 211 above to move, so that the tension of the thread passing through the guide wheel 210 and guide roller 211 is adjusted to be close to the set value, ensuring the stability of the thread during the pulling and winding process. Based on the air pump 6, metal shaping hose 61 and nozzle 62 forming a chip removal assembly, the air pump 6 delivers air to the metal shaping hose 61 and blows it away by the nozzle 62. The spray direction of the nozzle 62 is facing the guide wheel 210 and guide roller 211 at the corresponding position, so that the residual shavings on the guide wheel 210 and guide roller 211 can be blown away.
