Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment technology, specifically to a wire drawing machine with adjustable wire drawing diameter. Background Technology

[0002] Metal wire drawing machines are key equipment in the field of metal processing. They use the principle of stretching and deformation to gradually draw metal wires to the target specifications and are widely used in industries such as wire and cable, metal products, construction, and automobiles.

[0003] For example, CN119747414A discloses an adjustable wire drawing machine, which belongs to the field of wire drawing machines. It includes: a base; four support rods fixedly connected to the four bottom corners of the base; two mounting seats symmetrically fixed to the base; a rotating shaft rotatably mounted on the mounting seats; a mounting plate fixedly connected to the rotating shaft; a mounting roller movably mounted on the rotating shaft; a connecting plate fixedly connected to the mounting roller and movably mounted on the rotating shaft; a fixing assembly disposed between the mounting plate and the connecting plate; a drive motor fixedly connected to one of the mounting seats, with the output shaft of the drive motor fixedly connected to the rotating shaft; two slides; and two mounting brackets. The beneficial effect of this application is that it provides an adjustable wire drawing machine.

[0004] Although the above-mentioned wire drawing machine can control the wire drawing diameter to a certain extent, the above-mentioned equipment is not convenient in terms of adjusting the wire drawing diameter and the stability of subsequent support, which reduces the stability and efficiency of subsequent processing of the metal wire. Therefore, a wire drawing machine with adjustable wire drawing diameter is needed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a wire drawing machine with an adjustable wire drawing diameter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire drawing machine with adjustable wire diameter, comprising a support base for support, and two sets of aluminum profile columns symmetrically arranged at the center of the upper end surface of the support base.

[0007] The wire drawing device is provided in two sets, and the two sets of wire drawing devices are respectively arranged at the front and rear of the support base. The wire drawing device is used to draw and guide the metal wire.

[0008] The control device consists of two sets, each set being disposed on the upper end face of the aluminum profile column. The two sets of control devices are synchronously driven by a transmission shaft. The control device is used to draw and guide metal wires of different diameters.

[0009] Preferably, a servo motor is provided on the side end face of the wire drawing device near the top, and a motor bracket is provided on the side end face of the control device located at the rear, directly opposite the transmission shaft, and a reduction motor is provided at the input end of the motor bracket.

[0010] The wire drawing device includes two sets of support guide seats. Two sets of guide rollers are rotatably engaged on the inner end faces of the two sets of support guide seats near the front. Transmission gears are provided on the side end faces of the two sets of guide rollers. Wire drawing guide rollers are rotatably engaged at the middle and rear of the inner end faces of the two sets of support guide seats.

[0011] Preferably, the control device includes a positioning bracket, with symmetrically arranged alignment brackets at the center of the side end face of the positioning bracket, and a material guide device rotatably engaged at the center of the inner end face of the positioning bracket, a transmission device rotatably engaged at the upper part of the inner end face of the positioning bracket near the material guide device, and a drive pulley rotatably engaged at the top of the inner end face of the positioning bracket. The drive pulley and the transmission device are meshed and connected by a synchronous belt, and a material guide cylinder is provided at the bottom of the inner end face of the positioning bracket.

[0012] Preferably, the material guiding device includes a positioning turntable, with traction guide cylinders of different diameters equidistantly arranged on the rear end face of the positioning turntable, and a transmission groove wheel fixedly arranged at the center of the front end face of the positioning turntable. Five sets of limiting grooves are equidistantly opened on the side end face of the transmission groove wheel, and a groove wheel slide is opened between the two sets of limiting grooves on the side end face of the transmission groove wheel.

[0013] Preferably, the transmission device includes a notched chuck, a driven pulley is fixedly disposed at the center of the rear end face of the notched chuck, a positioning swing plate is fixedly disposed at the center of the front end face of the notched chuck, and a limit pivot is disposed at the end of the rear end face of the positioning swing plate.

[0014] Preferably, the two sets of guide rollers are meshed and connected by the two sets of transmission gears, and the rotation trajectory of the center of the five sets of traction guide cylinders coincides with the center of the guide cylinder, so that when the five sets of traction guide cylinders rotate cyclically, they can always coincide with the guide channel between the two sets of guide rollers, thereby improving the tension and stability of subsequent guiding and stretching of the metal wire.

[0015] Preferably, the driving pulley and the driven pulley are meshed together by the synchronous belt, which can effectively improve the stability and synchronization of subsequent transmission.

[0016] Preferably, the notched chuck is rotatably engaged with the transmission groove wheel via the limiting slot. The notched chuck is adapted to the groove of the groove wheel via the limiting pivot shaft, thereby causing the transmission groove wheel to rotate. When the positioning turntable is cyclically rotated, the positioning turntable can be cyclically rotated by the sliding limit between the limiting pivot shaft and the groove wheel groove, thereby driving the transmission groove wheel and the positioning turntable to rotate cyclically, thereby improving the accuracy of subsequent alignment of traction guide cylinders of different diameters between the two sets of guide rollers.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention, by setting up a control device, enables the reduction motor to synchronously drive two sets of notched chucks to rotate when drawing metal wires of different diameters via a transmission chuck shaft, a drive pulley, and a synchronous belt. This allows the notched chucks to be limited by the sliding limit of the limit shaft and the groove of the grooved wheel, thereby cyclically driving the transmission grooved wheel to rotate in a positioning manner. This allows the drawing guide cylinders of different diameters to be positioned at the drawing channel, thereby improving the equipment's adaptability to drawing different types of metal wires, as well as improving the convenience of control and the stability of processing different types of metal wires.

[0019] 2. By setting up a wire drawing device, the present invention enables two sets of guide rollers to rotate synchronously in opposite directions through transmission gears when drawing metal wire, thereby improving the stability of metal wire guidance. At the same time, the two sets of wire drawing guide rollers can provide sufficient wire drawing and extension space for the metal wire, further improving the stability of subsequent metal wire drawing and thus improving the efficiency of metal wire drawing.

[0031] The invention will be further described below with reference to the accompanying drawings.

[0032] Example 1

[0033] Please see Figure 1-7 One embodiment of the present invention provides a wire drawing machine with an adjustable wire drawing diameter, comprising a support base 1 for support, and two sets of aluminum profile columns 7 symmetrically arranged at the center of the upper end surface of the support base 1.

[0034] The wire drawing device 3 is provided in two sets, and the two sets of wire drawing devices 3 are respectively located at the front and rear of the support base 1. The wire drawing device 3 is used to draw and guide the metal wire.

[0035] The control device 6 has two sets, and the two sets of control devices 6 are respectively set on the upper end face of the aluminum profile column 7. The two sets of control devices 6 are synchronously driven by the transmission shaft 8. The control device 6 is used to draw and guide metal wires of different diameters.

[0036] A servo motor 2 is provided on the side end face of the wire drawing device 3 near the top. A motor bracket 4 is provided on the side end face of the control device 6 located at the rear, directly opposite the transmission bracket 8. A reduction motor 5 is provided at the input end of the motor bracket 4.

[0037] The wire drawing device 3 includes two sets of support guide seats 33 for support. Two sets of guide rollers 31 are rotatably engaged on the inner end face of the two sets of support guide seats 33 near the front. Transmission gears 32 are provided on the side end face of the two sets of guide rollers 31. Wire drawing guide rollers 34 are rotatably engaged on the middle and rear of the inner end face of the two sets of support guide seats 33.

[0038] like Figure 4 and Figure 5 The control device 6 includes a positioning bracket 61, with a symmetrical alignment bracket 63 arranged at the middle of the side end face of the positioning bracket 61. A guide device 62 is rotatably engaged at the middle of the inner end face of the positioning bracket 61. A transmission device 66 is rotatably engaged at the upper part of the inner end face of the positioning bracket 61 near the guide device 62. A drive pulley 64 is rotatably engaged at the top of the inner end face of the positioning bracket 61. The drive pulley 64 and the transmission device 66 are meshed and connected by a synchronous belt 65. A guide cylinder 67 is provided at the bottom of the inner end face of the positioning bracket 61.

[0039] like Figure 6 The material guiding device 62 includes a positioning turntable 624. The rear end face of the positioning turntable 624 is provided with traction guide cylinders 623 of different diameters at equal intervals. A transmission groove wheel 621 is fixedly provided at the center of the front end face of the positioning turntable 624. Five sets of limiting grooves 625 are provided at equal intervals on the side end face of the transmission groove wheel 621. A groove wheel slide groove 622 is provided on the side end face of the transmission groove wheel 621 between the two sets of limiting grooves 625.

[0040] like Figure 7 The transmission device 66 includes a notched chuck 664, a driven pulley 661 is fixedly provided at the center of the rear end face of the notched chuck 664, a positioning swing plate 663 is fixedly provided at the center of the front end face of the notched chuck 664, and a limit pivot 662 is provided at the end of the rear end face of the positioning swing plate 663.

[0041] Two sets of guide rollers 31 are meshed and connected by two sets of transmission gears 32. The rotation trajectory of the center of the five sets of traction guide cylinders 623 coincides with the center of the guide cylinder 67, so that when the five sets of traction guide cylinders 623 rotate 72 degrees in a cycle, they can always coincide with the guide channel between the two sets of guide rollers 31, thereby improving the tension and stability of subsequent guiding and stretching of the metal wire.

[0042] The driving pulley 64 and the driven pulley 661 are connected by a synchronous belt 65, which can effectively improve the stability and synchronization of subsequent transmission.

[0043] The notched chuck 664 is engaged with the transmission groove wheel 621 by a limiting slot 625. The engagement of the limiting slot 625 with the transmission groove wheel 621 facilitates the quick and stable locking of the transmission groove wheel 621 after it is reversed, thereby improving the stability of the limiting position after the transmission groove wheel 621 rotates.

[0044] The notched chuck 664 is adapted to the groove 622 of the slotted wheel via the limiting pivot 662, thereby driving the transmission slotted wheel 621 to rotate. When the positioning turntable 624 is rotated 72 degrees in a cycle, the positioning turntable 624 can be limited by the sliding of the limiting pivot 662 and the groove 622, thereby driving the transmission slotted wheel 621 and the positioning turntable 624 to rotate 72 degrees in a cycle, thereby improving the accuracy of the subsequent alignment of the traction guide cylinders 623 of different diameters between the two sets of guide rollers 31.

[0045] Working Principle: Before use, the operator can pass the metal wire to be processed through the two sets of guide rollers 31 and the two sets of drawing guide rollers 34 located in the middle of the support guide 33. Simultaneously, the metal wire can be positioned and passed through the traction guide cylinder 623, providing a guiding and limiting foundation for the wire drawing, thereby improving the subsequent wire drawing efficiency. During wire drawing guidance, the two sets of servo motors 2 can start synchronously, enabling the servo motors 2 to drive the two sets of guide rollers 31 to rotate synchronously in opposite directions through the two sets of transmission gears 32. This allows the two sets of guide rollers 31 to guide the metal wire, while the two sets of drawing guide rollers 34 can pull the metal wire. The guide device 62 located in the middle can further pull and guide the metal wire, thereby improving the wire drawing efficiency. If different metal wires need to be processed... In the wire drawing operation, the operator can start the reduction motor 5. At this time, the reduction motor 5 can synchronously drive the two sets of driving pulleys 64 to rotate through the transmission chuck 8. The two sets of driving pulleys 64 can drive the driven pulley 661 at the bottom to rotate through the synchronous belt 65. At the same time, the driven pulley 661 can drive the notched chuck 664 to rotate in a circle, so that the notched chuck 664 can drive the positioning swing plate 663 and the limit pin 662 to rotate in a circle. At this time, the positioning swing plate 663 can be limited by the sliding limit pin 662 and the groove 622 of the groove wheel, thereby driving the transmission groove wheel 621 to rotate intermittently. At this time, the transmission groove wheel 621 can drive the positioning turntable 624 to rotate. When the traction guide cylinder 623 of the preset diameter is positioned at the center position of the two sets of transmission gears 32, the control operation of drawing metal wires of different diameters is completed.
