Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a control mechanism of a wire drawing machine. Background Art

[0002] A wire drawing machine belongs to the pre-processing equipment for the production of metal products such as standard parts. The wire drawing machine is widely used in the production and pre-processing of metal products such as steel wires, wire ropes, and diamond wires. The purpose is to subject wire rods or bars to the drawing process of the wire drawing machine, so that the diameter, roundness, internal metallographic structure, surface finish, and straightness of the wire rods or bars meet the raw material processing requirements for the production of metal products such as standard parts. From a technical perspective, the core components of the wire drawing machine include drawing dies and a transmission system. Drawing dies are usually made of materials with high hardness and high wear resistance, such as tungsten carbide, etc. The design of these dies is extremely crucial. Different die shapes and sizes can precisely control the dimensions of wire rods or bars. During the drawing process, the internal channels of the dies will generate a uniform extrusion force on the metal material, thereby achieving a gradual reduction in diameter. The transmission system is responsible for providing a stable and adjustable drawing force, and its accuracy and stability directly affect the quality of the entire drawing process. Advanced wire drawing machine transmission systems often adopt variable frequency speed regulation technology, which can flexibly adjust the drawing speed according to different metal materials and processing requirements. In the actual production process, different types of metal products have different performance requirements for the wire drawing machine. Taking the production of steel wires as an example, high-strength steel wires are used in fields such as bridges and buildings, and have extremely high requirements for their internal metallographic structure and mechanical properties. When the wire drawing machine processes such steel wires, it is necessary to precisely control parameters such as the drawing temperature, speed, and deformation amount to ensure that the steel wires have a uniform metallographic structure and high strength after drawing. The production of wire ropes pays more attention to the surface finish and softness of the wire rods, which requires the wire drawing machine to minimize damage to the surface of the wire rods during the drawing process and improve the softness of the wire rods through special processing techniques. In order to improve the usability of traditional wire drawing machines, therefore, a control mechanism of a wire drawing machine is particularly needed.

[0003] However, the existing traditional wire drawing machines cannot control the size of the take-up tension, resulting in the diameter of the drawn wire being unable to adapt to industrial production due to the tension, causing waste of resources and low practicality. The replacement of the take-up spool of traditional wire drawing machines is often rather cumbersome. When different specifications of metal wires need to be produced, the loading and unloading process of the take-up spool is time-consuming and laborious, reducing the overall production efficiency. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a wire drawing machine control mechanism to solve the problems in the above-mentioned background technology. There is a wire drawing machine control mechanism, but in the existing traditional wire drawing machine, the wire take-up tension cannot be controlled, so that the diameter of the drawn wire cannot adapt to industrial production due to the tension, resulting in waste of resources and low practicability. The replacement of the take-up reel of the traditional wire drawing machine is often cumbersome. When producing metal wires of different specifications, the loading and unloading process of the take-up reel is time-consuming and laborious, reducing the overall production efficiency.

[0006] The control mechanism includes a support, a first motor, a forward threaded rod, a slider, a sliding hole, a stop block, a reverse threaded rod, a tension pulley and a sliding rod. The upper surface of the workbench is fixedly connected with a support. One side surface of the top end of the support is fixedly connected with a first motor. The bottom surface of the first motor is fixedly connected with a forward threaded rod. The outer wall surface of the forward threaded rod is threadedly connected with a slider. The inner wall surface of the slider is provided with a sliding hole. The bottom surface of the forward threaded rod is fixedly connected with a stop block. The bottom surface of the stop block is fixedly connected with a reverse threaded rod. One side surface of the slider is fixedly connected with a tension pulley. The other side inner surface of the support is fixedly connected with a sliding rod. The forward threaded rod, the stop block and the reverse threaded rod are all rotatable inside one end of the support, and the groove opened inside one end of the support limits the slider.

[0007] Preferably, the support legs are symmetrically arranged at the four corners of the workbench with the central axis of the workbench as the symmetry axis, and the shock pads are evenly distributed at the bottom of each group of support legs.

[0008] Preferably, the fixed shaft is fixedly connected to one side of the workbench through the connection disk and the fixing bolts, and multiple groups of fixing bolts are arranged on the surface of the connection disk.

[0009] Preferably, multiple groups of sliders are arranged inside the support, and two of the sliders are symmetrically arranged on the surfaces of the forward threaded rod and the reverse threaded rod respectively with the horizontal central axis of the stop block as the symmetry axis.

[0010] Preferably, the transmission mechanism includes a second motor, a rotating shaft, a first roller, a crawler, a second roller, a transmission shaft, a guide wheel, a wire winding cylinder, a threaded hole, a limiting hole, a threaded bolt, a telescopic hole, a telescopic spring, a limiting plate and a limiting block. The upper surface of the workbench is fixedly connected with a second motor, one end surface of the second motor is fixedly connected with a rotating shaft, the outer wall surface of the rotating shaft is fixedly connected with a first roller, the outer wall surface of the first roller is attached to the crawler, the inner wall surface of the other end of the crawler is attached to a second roller, one end surface of the second roller is fixedly connected with a transmission shaft, the outer wall surface of the transmission shaft is fixedly connected with a guide wheel, one end surface of the rotating shaft is threadedly connected with a wire winding cylinder, the inner wall surface of one end of the rotating shaft is provided with a threaded hole, the two side surfaces of the threaded hole are provided with limiting holes, the inner wall surface of the threaded hole is threadedly connected with a threaded bolt, the inner wall surface of the threaded bolt is provided with a telescopic hole, the inner end surface of the telescopic hole is fixedly connected with a telescopic spring, one end surface of the telescopic spring is fixedly connected with a limiting plate, and one end surface of the limiting plate is fixedly connected with a limiting block.

[0011] Preferably, the wire winding cylinder is threadedly connected with the rotating shaft through the threaded bolt and the threaded hole, and the limiting plate and the limiting block cooperate with each other through the telescopic spring to form a telescopic structure.

[0012] Preferably, the position of the limiting block corresponds to the position of the limiting hole, and the outer wall dimension of the limiting block matches the inner wall dimension of the limiting hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: for a wire drawing machine control mechanism, through the settings of the control mechanism and the transmission mechanism, when it is necessary to adjust the tension of the wire, the first motor is started. The operation of the first motor drives the forward threaded rod to rotate. Since the forward threaded rod is in a threaded connection with the slider, and the slider is restricted by the slide rod and can only move in a straight line direction, the other slide rod passes through the slide hole on the slider to play a guiding role. The rotation of the forward threaded rod will cause the slider to move downward along the forward threaded rod. As the slider moves, the tension pulley fixed on one side surface of the slider will also move downward synchronously. At this time, the wrap angle of the wire on the tension pulley changes, thereby increasing the tension of the wire. When the first motor rotates in reverse, the forward threaded rod rotates in the reverse direction, and the slider will move upward along the forward threaded rod and the slide rod. At the same time, since a stopper is fixedly connected to the bottom surface of the forward threaded rod, and the stopper is connected to the reverse threaded rod, when the slider moves into contact with the reverse threaded rod, the reverse threaded rod will also participate in the driving process of the slider. The rotation of the reverse threaded rod will cause the slider to continue to move upward along the reverse threaded rod, thereby driving the tension pulley to move upward, the included angle of the wire on the tension pulley decreases, and the tension of the wire also decreases accordingly. Through the precise control of the forward and reverse rotation of the first motor, the precise adjustment of the position of the tension pulley can be realized, and then the tension of the wire can be precisely controlled, so that the diameter of the wire drawing can meet the requirements of industrial production, avoid resource waste caused by unstable tension, and improve the practicability of production. When it is necessary to perform the wire winding operation, the second motor is started. The second motor starts to operate and drives the rotating shaft to rotate. The rotation of the rotating shaft drives the first roller fixedly connected to its outer wall to rotate synchronously. When the first roller rotates, since the crawler is attached to the outer wall surface of the first roller, and the other end of the crawler is attached to the inner wall surface of the second roller, the rotation of the first roller transmits power through the crawler, causing the second roller to rotate accordingly. The rotation of the second roller drives the transmission shaft connected to it to rotate, and further causes the guide wheel fixed on the outer wall of the transmission shaft to rotate, guiding the wire to the wire winding cylinder. When installing the wire winding cylinder, the wire winding cylinder is sleeved on one end of the rotating shaft, and the threaded bolt is rotated to make it rotate in the threaded hole. During the rotation of the threaded bolt, due to the action of the telescopic spring, the limiting plate and the limiting block will be compressed into the telescopic hole. When the threaded bolt is completely screwed into the threaded hole, the limiting block pops out under the elastic force of the telescopic spring and is stuck in the limiting hole, thereby firmly fixing the wire winding cylinder on the rotating shaft. When the rotating shaft rotates, the wire winding cylinder can be driven to rotate to realize the wire winding operation of the wire. When it is necessary to replace wire winding cylinders of different specifications, the threaded bolt is rotated again to make the limiting block withdraw from the limiting hole, and then the wire winding cylinder can be easily removed and a new wire winding cylinder can be replaced for work. This design facilitates the operation and improves the adaptability and production efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-6, the present utility model provides a technical solution: a wire drawing machine control mechanism, including a workbench 1, the bottom surface of the workbench 1 is fixedly connected with support legs 2, the bottom surface of the support legs 2 is fixedly connected with shock pads 3, a fixed shaft 4 penetrates through one side surface above the workbench 1, the outer wall surface of one end of the fixed shaft 4 is fixedly connected with a connection plate 5, the surface of the connection plate 5 is connected with a fixing bolt 6, the outer wall surface of the other end of the fixed shaft 4 is rotatably connected with a wire pay-off reel 7, a wire 8 is wound around the surface of the wire pay-off reel 7, a control mechanism 9 is arranged on the upper surface of the workbench 1, and a transmission mechanism 10 is arranged on the upper surface of the workbench 1;

[0023] The control mechanism 9 includes a support 901, a first motor 902, a forward threaded rod 903, a slider 904, a sliding hole 905, a stop block 906, a reverse threaded rod 907, a tension pulley 908, and a sliding rod 909. A support 901 is fixedly connected to the upper surface of the workbench 1. One side surface of the top end of the support 901 is fixedly connected to a first motor 902. The bottom surface of the first motor 902 is fixedly connected to a forward threaded rod 903. The outer wall surface of the forward threaded rod 903 is threadedly connected to a slider 904. A sliding hole 905 is provided on the inner wall surface of the slider 904. The bottom surface of the forward threaded rod 903 is fixedly connected to a stop block 906. The bottom surface of the stop block 906 is fixedly connected to a reverse threaded rod 907. One side surface of the slider 904 is fixedly connected to a tension pulley 908. The other inner surface of the support 901 is fixedly connected to a sliding rod 909. The forward threaded rod 903, the stop block 906, and the reverse threaded rod 907 all rotate inside one end of the support 901. The groove provided inside one end of the support 901 limits the slider 904. Through the setting of the control mechanism 9, when it is necessary to adjust the tension of the wire, the first motor 902 is started. The operation of the first motor 902 drives the forward threaded rod 903 to rotate. Since the forward threaded rod 903 and the slider 904 are in a threaded connection relationship, and the slider 904 is restricted by the sliding rod 909 and can only move in a straight line. The other sliding rod 909 passes through the sliding hole 905 on the slider 904 to play a guiding role. The rotation of the forward threaded rod 903 will cause the slider 904 to move downward along the forward threaded rod 903. As the slider 904 moves, the tension pulley 908 fixedly connected to one side surface of the slider 904 will also move downward synchronously. At this time, the angle of the wire on the tension pulley 908 changes, thereby increasing the tension of the wire. When the first motor 902 rotates in reverse, the forward threaded rod 903 rotates in the reverse direction, and the slider 904 will move upward along the forward threaded rod 903 and the sliding rod 909. At the same time, since the bottom surface of the forward threaded rod 903 is fixedly connected to a stop block 906, and the stop block 906 is connected to the reverse threaded rod 907. When the slider 904 moves into contact with the reverse threaded rod 907, the reverse threaded rod 907 will also participate in the driving process of the slider 904. The rotation of the reverse threaded rod 907 will cause the slider 904 to continue to move upward along the reverse threaded rod 907, thereby driving the tension pulley 908 to move upward. The angle of the wire on the tension pulley 908 decreases, and the tension of the wire also decreases accordingly. Through the precise control of the forward and reverse rotation of the first motor 902, the precise adjustment of the position of the tension pulley 908 can be achieved, and then the tension of the wire can be precisely controlled, so that the diameter of the drawn wire can meet the requirements of industrial production, avoiding resource waste caused by unstable tension, and improving the practicality of production.

[0024] Furthermore, the support legs 2 are symmetrically arranged at the four corners of the workbench 1 with respect to the central axis of the workbench 1, and the shock pads 3 are evenly distributed at the bottom of each group of support legs 2. Through the arrangement of the shock pads 3, the shock pads 3 are evenly distributed at the bottom of each group of support legs 2. During the operation of the equipment, especially when the wire drawing machine is drawing metal wires, certain vibrations will be generated. The shock pads 3 can effectively absorb these vibrations and reduce the transmission of vibrations to the ground. This can not only reduce noise but also avoid the adverse effects of vibrations on the equipment itself and the surrounding environment, and prolong the service life of the equipment.

[0025] Furthermore, the fixed shaft 4 is fixedly connected to one side of the workbench 1 through the connecting disk 5 and the fixing bolts 6. Multiple groups of fixing bolts 6 are arranged on the surface of the connecting disk 5. Through the arrangement of the fixing bolts 6, the design of multiple groups of fixing bolts 6 increases the firmness of the connection, enabling the fixed shaft 4 to withstand greater forces during operation without loosening or displacement. This reliable fixing method ensures the stable operation of the components associated with the fixed shaft 4, thus ensuring the smooth progress of the wire drawing process and improving production efficiency and product quality.

[0026] Furthermore, multiple groups of sliders 904 are arranged inside the support 901, and two of the sliders 904 are symmetrically arranged on the surfaces of the forward threaded rod 903 and the reverse threaded rod 907 with respect to the transverse central axis of the stop block 906. Through the arrangement of the sliders 904, multiple sliders 904 can be used to install multiple tension wheels 908, thereby enabling tension adjustment of the wire from multiple positions, improving the uniformity of tension control. The symmetrically arranged sliders 904, in cooperation with the forward threaded rod 903 and the reverse threaded rod 907, can more precisely balance the tension on both sides of the wire, keeping the wire 8 in a stable state during the drawing process, reducing the diameter deviation of the wire 8 caused by uneven tension, and improving product quality and production stability.

[0027] Further, the transmission mechanism 10 includes a second motor 1001, a rotating shaft 1002, a first roller 1003, a crawler 1004, a second roller 1005, a transmission shaft 1006, a guide wheel 1007, a wire winding drum 1008, a threaded hole 1009, a limiting hole 1010, a threaded bolt 1011, a telescopic hole 1012, a telescopic spring 1013, a limiting plate 1014 and a limiting block 1015. The upper surface of the workbench 1 is fixedly connected with a second motor 1001. One end surface of the second motor 1001 is fixedly connected with a rotating shaft 1002. The outer wall surface of the rotating shaft 1002 is fixedly connected with a first roller 1003. The outer wall surface of the first roller 1003 is attached to a crawler 1004. The inner wall surface of the other end of the crawler 1004 is attached to a second roller 1005. One end surface of the second roller 1005 is fixedly connected with a transmission shaft 1006. The outer wall surface of the transmission shaft 1006 is fixedly connected with a guide wheel 1007. One end surface of the rotating shaft 1002 is threadedly connected with a wire winding drum 1008. The inner wall surface of one end of the rotating shaft 1002 is provided with a threaded hole 1009. The two side surfaces of the threaded hole 1009 are provided with limiting holes 1010. The inner wall surface of the threaded hole 1009 is threadedly connected with a threaded bolt 1011. The inner wall surface of the threaded bolt 1011 is provided with a telescopic hole 1012. The inner end surface of the telescopic hole 1012 is fixedly connected with a telescopic spring 1013. One end surface of the telescopic spring 1013 is fixedly connected with a limiting plate 1014. One end surface of the limiting plate 1014 is fixedly connected with a limiting block 1015. Through the setting of the transmission mechanism 10, when the wire winding operation needs to be carried out, the second motor 1001 is started, and the second motor 1001 starts to operate, driving the rotating shaft 1002 to rotate. The rotation of the rotating shaft 1002 drives the first roller 1003 fixedly connected to its outer wall to rotate synchronously. When the first roller 1003 rotates, since the crawler 1004 is attached to the outer wall surface of the first roller 1003 and the other end of the crawler 1004 is attached to the inner wall surface of the second roller 1005, the rotation of the first roller 1003 transmits power through the crawler 1004, causing the second roller 1005 to rotate accordingly. The rotation of the second roller 1005 drives the transmission shaft 1006 connected thereto to rotate, and further causes the guide wheel 1007 fixed on the outer wall of the transmission shaft 1006 to rotate, guiding the silk thread onto the wire winding drum 1008. When installing the wire winding drum 1008, the wire winding drum 1008 is sleeved on one end of the rotating shaft 1002. By rotating the threaded bolt 1011, it rotates in the threaded hole 1009. During the rotation of the threaded bolt 1011, due to the action of the telescopic spring 1013, the limiting plate 1014 and the limiting block 1015 will be compressed and enter the telescopic hole 1012. After the threaded bolt 1011 is completely screwed into the threaded hole 1009, the limiting block 1015 pops out under the elastic force of the telescopic spring 1013 and is stuck into the limiting hole 1010, thereby firmly fixing the wire winding drum 1008 on the rotating shaft 1002. When the rotating shaft 1002 rotates,It can drive the wire take-up reel 1008 to rotate, realizing the wire take-up operation. When it is necessary to replace the wire take-up reel of different specifications, rotate the threaded bolt 1011 again to make the limit block 1015 withdraw from the limit hole 1010, and then the wire take-up reel 1008 can be easily removed and a new wire take-up reel can be installed for work. This design facilitates the operation and improves the adaptability and production efficiency of the equipment.

[0028] Furthermore, the wire take-up reel 1008 is threadedly connected to the rotating shaft 1002 through the threaded bolt 1011 and the threaded hole 1009. The limit plate 1014 and the limit block 1015 cooperate with each other through the telescopic spring 1013 to form a telescopic structure. Through the settings of the threaded bolt 1011 and the telescopic spring 1013, the threaded connection method is convenient for installation and disassembly. The operator can quickly complete the replacement of the wire take-up reel 1008 through simple rotation operations, improving the efficiency of equipment maintenance and production adjustment. When installing the wire take-up reel 1008, when the wire take-up reel 1008 is sleeved on the rotating shaft 1002 and the threaded bolt 1011 is tightened, the limit block 1015 will automatically snap into the limit hole 1010 under the action of the telescopic spring 1013 to achieve automatic positioning. This self-adaptive positioning mechanism can ensure a tighter and more stable connection between the wire take-up reel 1008 and the rotating shaft 1002, preventing the position of the wire take-up reel 1008 from shifting due to factors such as vibration during operation.

[0029] Furthermore, the position of the limit block 1015 corresponds to the position of the limit hole 1010, and the outer wall size of the limit block 1015 matches the inner wall size of the limit hole 1010. Through the setting of the limit hole 1010, the accuracy of the positioning is guaranteed. After the limit block 1015 snaps into the limit hole 1010, the two can fit tightly without shaking or excessive gaps, further enhancing the reliability of the connection between the wire take-up reel 1008 and the rotating shaft 1002, ensuring the stable and efficient operation of the wire take-up process, and improving the working performance of the entire equipment.

[0030] Working principle: First, the wire 8 is wound around the wire pay-off reel 7. The wire pay-off reel 7 is installed on one side of the workbench 1 through the cooperation of the fixed shaft 4 with the connecting plate 5 and the fixing bolt 6. When the equipment starts to operate, the wire pay-off reel 7 rotates on the fixed shaft 4 as the wire is pulled out. Since the support legs 2 provide stable support for the entire workbench 1, and the shock pads 3 at the bottom can reduce the impact of the vibrations generated during the operation of the equipment on the entire system, ensuring the smooth progress of the wire pay-off process. When it is necessary to adjust the tension of the wire, start the first motor 902. The first motor 902 rotates to drive the forward threaded rod 903 to rotate. Since the forward threaded rod 903 is threadedly connected to the slider 904, and the slider 904 is restricted by the slide rod 909 and can only move in a straight line. The other slide rod 909 passes through the slide hole 905 on the slider 904 to play a guiding role. The rotation of the forward threaded rod 903 will cause the slider 904 to move downward along the forward threaded rod 903. As the slider 904 moves, the tension pulley 908 fixed on one side surface of the slider 904 will also move downward synchronously. At this time, the angle of the wire on the tension pulley 908 changes, thereby increasing the tension of the wire. When the first motor 902 rotates in reverse, the forward threaded rod 903 rotates in the reverse direction, and the slider 904 will move upward along the forward threaded rod 903 and the slide rod 909. At the same time, since the bottom surface of the forward threaded rod 903 is fixedly connected with a stop block 906, and the stop block 906 is connected to the reverse threaded rod 907. When the slider 904 moves into contact with the reverse threaded rod 907, the reverse threaded rod 907 will also participate in the driving process of the slider 904. The rotation of the reverse threaded rod 907 will cause the slider 904 to continue to move upward along the reverse threaded rod 907, thereby driving the tension pulley 908 to move upward. The angle of the wire on the tension pulley 908 decreases, and the tension of the wire also decreases accordingly. Through the precise control of the forward and reverse rotation of the first motor 902, the precise adjustment of the position of the tension pulley 908 can be achieved, and then the tension of the wire can be precisely controlled, so that the diameter of the drawn wire can meet the requirements of industrial production, avoiding resource waste caused by unstable tension, and improving the practicality of production. When it is necessary to perform the wire winding operation, start the second motor 1001. The second motor 1001 starts to operate, driving the rotating shaft 1002 to rotate. The rotation of the rotating shaft 1002 drives the first roller 1003 fixedly connected to its outer wall to rotate synchronously. When the first roller 1003 rotates, since the crawler 1004 is in contact with the outer wall surface of the first roller 1003, and the other end of the crawler 1004 is in contact with the inner wall surface of the second roller 1005, the rotation of the first roller 1003 transmits power through the crawler 1004, causing the second roller 1005 to rotate accordingly. The rotation of the second roller 1005 drives the transmission shaft 1006 connected to it to rotate, and further causes the guide wheel 1007 fixed on the outer wall of the transmission shaft 1006 to rotate, guiding the wire onto the wire winding reel 1008. When installing the wire winding reel 1008, the wire winding reel 1008 is sleeved on one end of the rotating shaft 1002,By rotating the threaded bolt 1011 to make it rotate within the threaded hole 1009, during the rotation of the threaded bolt 1011, due to the action of the telescopic spring 1013, the limiting plate 1014 and the limiting block 1015 will be compressed and enter the telescopic hole 1012. When the threaded bolt 1011 is completely screwed into the threaded hole 1009, the limiting block 1015 pops out under the elastic force of the telescopic spring 1013 and snaps into the limiting hole 1010, thereby firmly fixing the wire reel 1008 on the rotating shaft 1002. When the rotating shaft 1002 rotates, it can drive the wire reel 1008 to rotate, realizing the wire winding operation. When it is necessary to replace the wire reel with different specifications, rotate the threaded bolt 1011 again to make the limiting block 1015 withdraw from the limiting hole 1010, and then the wire reel 1008 can be easily removed and a new wire reel can be installed for work.
