Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, specifically a wire drawing machine for producing steel strand. Background Technology

[0002] Steel strand is a steel product made of multiple steel wires twisted together. During the production process, a wire drawing machine is used to draw the steel wires within the strand, thereby improving their rust resistance and wear resistance. In the prior art, patent CN 118976791 B discloses a wire drawing machine for steel strand production, comprising: a drawing table, and support plates one and two fixedly installed at the bottom of the drawing table. The machine is characterized by a support frame fixedly installed on the top of the drawing table; a concave seat one fixedly installed on the side of support plate one away from support plate two, with a feed roller inside the concave seat one; and at least one take-up unit on the side of support plate two away from support plate one, used to take up the drawn steel strand. Two vertical plates are fixedly installed on the inner top wall of the support frame, and the same central shaft is rotatably mounted on the two vertical plates. The device is equipped with a disc, which allows for quick replacement of drawing dies with different inner diameters, improving drawing efficiency and ensuring that drawing powder adheres fully to the steel strand. The device contains multiple sets of drawing dies with different inner diameters, and different drawing requirements necessitate different dies. However, the drawing dies themselves experience wear during use. Since different drawing dies are fixed in place by corresponding single-set locking elements, only one set of drawing dies can be replaced per operation. This limits the overall efficiency of die replacement. Therefore, we propose a steel strand production drawing machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a steel strand production wire drawing machine. This device can release the installation limit of each wire drawing die in one step by changing the components, without the need to replace the wire drawing dies one by one, thereby improving the overall wire drawing die replacement rate of the device. At the same time, the device can automatically limit the installation of each wire drawing die simultaneously by using the torsion spring to reset the torque in the later stage, further improving the overall wire drawing die replacement rate of the device. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a steel strand production wire drawing machine, including a wire drawing table, a wire drawing shell provided on the upper left side of the wire drawing table, a mold plate installed inside the wire drawing shell, and a wire drawing mold replacement mechanism; The wire drawing die replacement mechanism includes a die shell, wire drawing dies, a synchronous locking assembly, and a limiting assembly. The die shells are arranged in a ring shape on the inner outer edge of the die plate. Wire drawing dies are inserted into the interior of each die shell. A synchronous locking assembly is located on the left side of the die plate. The synchronous locking assembly is installed in conjunction with the wire drawing die. A limiting assembly is provided between the synchronous locking assembly and the die plate. This device can release the installation limit of each wire drawing die in one step by replacing the components, eliminating the need to replace each wire drawing die individually, thus improving the overall wire drawing die replacement rate within the device. Furthermore, the device can automatically limit the installation of each wire drawing die simultaneously by using the torsion spring to reset the torque, further improving the overall wire drawing die replacement rate within the device.

[0005] Furthermore, a lubrication box is provided at the left end of the bottom wall of the drawing shell.

[0006] Furthermore, a connecting seat is provided at the right end of the top wall of the wire drawing shell. The lower middle part of the connecting seat is rotatably connected to a rotating shaft through a bearing. The left end of the rotating shaft is fixedly connected to the middle right side of the mold plate, thereby limiting the spatial position of the mold plate in the wire drawing machine for steel strand production.

[0007] Furthermore, the synchronous locking assembly includes a second rotating shaft, a ring frame, a third rotating shaft, locking rods, guide grooves, and a first positioning rod. The ring frame is rotatably connected to the middle left side of the mold plate via the second rotating shaft.

The left side of the mold plate is provided with evenly distributed ring-shaped first positioning rods. Each first positioning rod is slidably connected to the vertically adjacent guide groove, so that the insertion limiting elements of each wire drawing die in the device can move simultaneously.

[0008] Furthermore, the limiting component includes a connecting frame, a rotating ring, and a torsion spring. The connecting frame is located on the left side of the mold plate. A rotating ring is provided at the left end of the second rotating shaft. A torsion spring is movably sleeved on the outer left end of the second rotating shaft. The left end of the torsion spring is fixedly connected to the right side of the rotating ring, and the right end of the torsion spring is fixedly connected to the left side of the connecting frame, so that each wire drawing die in the device can be automatically inserted and limited at the same time.

[0009] Furthermore, the wire drawing die replacement mechanism also includes a second positioning rod, which is located on the left side of the die plate. The second positioning rod is installed in conjunction with the ring frame to limit the forward and reset rotation amplitude of the ring frame inside the wire drawing machine for steel strand production.

[0010] Furthermore, the upper and lower walls of the drawing shell are provided with reinforcing seats, and the outer edges of the left and right sides of the mold plate are provided with annular grooves.

[0011] Furthermore, the left side of the mold plate is provided with a second annularly evenly distributed scale groove, and the left side of the lower reinforcing seat is provided with a first scale groove. The first scale groove and the second scale groove are fitted together. The right side of the connecting seat is provided with a rectangular shell.

The worm wheel is meshed with the worm gear to change the drawing mold in the steel strand production drawing machine.

[0012] Furthermore, it also includes a control switch, which is located outside the drawing table. The input end of the control switch is electrically connected to the output end of an external power supply. A servo motor is provided on the right side of the top wall of the drawing table. The input end of the servo motor is electrically connected to the output end of the control switch.

[0016] 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.

[0017] Please see Figure 1-6 This embodiment provides a technical solution: a steel strand production wire drawing machine, including a drawing table 1, a drawing shell 3 on the upper left side of the drawing table 1, a mold plate 8 installed inside the drawing shell 3, and a control switch 2 located outside the drawing table 1. The input terminal of the control switch 2 is electrically connected to the output terminal of an external power supply. A servo motor 18 is provided on the right side of the top wall of the drawing table 1, the input terminal of the servo motor 18 is electrically connected to the output terminal of the control switch 2, and a take-up reel 19 is provided on the output shaft of the servo motor 18. The device is used to control the steel strand production process. During the wire drawing operation, the initial end of the steel wire is passed from left to right through the first round hole on the left and right walls of the wire drawing shell 3, the second round hole on the left and right walls of the lubrication box 4, and the wire drawing die 92 at the bottom of the device (the wire drawing diameters of the wire drawing dies 92 in the device are different). The initial end of the steel wire is then wound and fixed onto the take-up reel 19. The servo motor 18 is started by the control switch 2, and its output shaft drives the take-up reel 19 to rotate, thereby performing the wire drawing and winding operation. The wire drawing die 92 changes the diameter of the steel wire. The device also includes a wire drawing die changing mechanism 9. The bottom left end of the drawing shell 3 is provided with a lubrication box 4. The lower end of the interior of the lubrication box 4 is rotatably connected to two transversely symmetrically distributed limiting rollers 5 through a sealed bearing. When the initial end of the steel wire passes through the lubrication box 4, the steel wire passes under the two limiting rollers 5 inside the lubrication box 4. The limiting rollers 5 make the steel wire passing through the lubrication box 4 pass through the bottom of the lubrication box 4, which facilitates the lubricating powder inside the lubrication box 4 to contact and lubricate the outer surface of the steel wire, which is convenient for subsequent wire drawing operations. A connecting seat 6 is provided on the right end of the top wall of the wire drawing shell 3. The lower middle part of the connecting seat 6 is rotatably connected to a rotating shaft 7 via a bearing. The left end of the rotating shaft 7 is fixedly connected to the middle right side of the mold plate 8. A second annularly distributed scale groove 13 is provided on the left side of the mold plate 8. A first scale groove 12 is provided on the left side of the lower reinforcing seat 11. The first scale groove 12 and the second scale groove 13 are fitted together. A rectangular shell 14 is provided on the right side of the connecting seat 6. A worm gear 15 is rotatably connected to the front and rear walls of the rectangular shell 14 via a bearing. A handwheel 17 is provided at the front end of the worm gear 15. The right end of the rotating shaft 7 is located inside the rectangular shell 14. The device is equipped with a worm gear 16, which meshes with the worm 15. When the wire drawing die 92 of the device is changed according to the diameter requirement after wire drawing, the operator turns the handwheel 17 to drive the worm 15 to rotate. During the rotation of the worm 15, the worm gear 16 drives the die plate 8 to rotate through the rotating shaft 7, thereby changing the wire drawing die 92 in the die plate 8 accordingly. During this process, the operator moves the scale groove 13 adjacent to the corresponding wire drawing die 92 to the closest vertical position to the scale groove 12, thereby accurately positioning the changed wire drawing die 92. The wire drawing die changing mechanism 9 includes a die shell 91, a wire drawing die 92, a synchronous locking assembly 93, and a limiting assembly 94. The die shells 91 are evenly arranged in a ring on the inner outer edge of the die plate 8. Wire drawing dies 92 are inserted into the interior of each die shell 91. The synchronous locking assembly 93 is located on the left side of the die plate 8 and is installed in conjunction with the wire drawing die 92. A limiting assembly 94 is provided between the synchronous locking assembly 93 and the die plate 8. The synchronous locking assembly 93 includes a second rotating shaft 931, a ring frame 932, a third rotating shaft 933, a locking rod 934, a guide groove 935, and a first positioning rod 936. The ring frame 932 is rotatably connected to the middle left side of the die plate 8 via the second rotating shaft 931. The left side of the ring frame 932 has an evenly arranged ring... The fabric rotating shaft 933 has a locking rod 934 rotatably connected to its left end via a bearing 2. The locking rod 934 is installed in conjunction with the vertically adjacent drawing die 92. A guide groove 935 is provided in the middle of each locking rod 934. A ring of evenly distributed positioning rods 936 is provided on the left side of the die plate 8. The positioning rods 936 are slidably connected to the vertically adjacent guide grooves 935. The limiting assembly 94 includes a connecting frame 941, a rotating ring 942, and a torsion spring 943. The connecting frame 941 is located on the left side of the die plate 8. A rotating ring 942 is provided at the left end of the rotating shaft 931. A torsion spring 943 is movably sleeved on the outer left end of the rotating shaft 931. The left end of the torsion spring 943 is fixedly connected to the right side of the rotating ring 942, and the right end of the torsion spring 943 is connected to the connecting frame 941. The wire drawing die replacement mechanism 9 also includes a second positioning rod 95, which is located on the left side of the die plate 8. The second positioning rod 95 is installed in conjunction with the ring frame 932. When the worn wire drawing die 92 is replaced after a period of use, the rotating ring 942 is rotated to drive the ring frame 932 to rotate in the opposite direction via the second rotating shaft 931. The ring frame 932 drives the corresponding locking rod 934 to rotate synchronously via the third rotating shaft 933. During this process, through the sliding connection between the guide groove 935 inside the locking rod 934 and the corresponding first positioning rod 936, the end of the locking rod 934 near the center of the die plate 8 rotates in the positive direction around the axis of the third rotating shaft 933, and the right side of the end of the locking rod 934 away from the center of the die plate 8 rotates in the positive direction. The left sides of adjacent wire drawing dies 92 slide apart, thereby releasing the lateral insertion limit on each wire drawing die 92. This releases the insertion limit on all wire drawing dies 92 in one step. The wire drawing die 92 is then removed horizontally to the left from its corresponding die housing 91 and replaced. During this process, the torsion spring 943's rotational torque increases as the rotating ring 942 rotates counter-clockwise. After the wire drawing die 92 is replaced, the operator releases the knob torque applied to the rotating ring 942. The reset torque of the torsion spring 943 causes the rotating ring 942 to rotate clockwise and reset via the rotating shaft 931. During this process, the end of the locking rod 934 furthest from the center of the die plate 8 resets using the same principle. The right side of the locking rod 934 furthest from the center of the die plate 8 has a rounded chamfer.The curved chamfer creates an initial lateral contact gap between the right end of the locking rod 934, away from the center of the mold plate 8, and the left side of the corresponding wire drawing mold 92. This gap, combined with the contact pressure applied by the curved chamfer, allows the right end of the locking rod 934, away from the center of the mold plate 8, to move towards the left side of the corresponding wire drawing mold 92 while simultaneously applying a force to the wire drawing mold 92 to penetrate into the corresponding mold housing 91. This allows for synchronous self-fixing of the replaced wire drawing mold 92. During this process, the positioning rod 95 limits the rotation amplitude of the annular frame 932, preventing excessive rotation of the annular frame 932 under the action of the torsion spring 943 from causing the locking rod 93 to contact the corresponding wire drawing mold. If contact separation occurs at point 92, after the device has been used for a period of time, the connecting frame 941, the rotating ring 942, and the torsion spring 943 between them should be completely removed and replaced (the connecting frame 941 is fixed to the left side of the mold plate 8 by bolt one, and the rotating ring 942 is fixed to the left end of the rotating shaft two 931 by bolt two). This prevents the torsion spring 943 from aging due to long-term use. By replacing components, the device can release the installation limit of each wire drawing die in one step, eliminating the need to replace each die individually, thus improving the overall die replacement rate within the device. Furthermore, the device can automatically limit the installation of each die simultaneously by using the reset torque of the torsion spring 942, further improving the overall die replacement rate within the device. The upper and lower walls of the wire drawing shell 3 are provided with reinforcing seats 11, and the outer edges of the left and right sides of the mold plate 8 are provided with annular grooves 10. The end of the reinforcing seat 11 near the center of the mold plate 8 is slidably connected to the annular groove 10. During the operation of the device, the horizontal right pressure applied to the wire drawing mold 92 by the sliding engagement between the upper and lower reinforcing seats 11 and the annular groove 10 is borne by the wire drawing mold 92 during the wire drawing process, so as to prevent the pressure from acting vertically along the wire drawing mold 92 to the bearing connection between the rotating shaft 7 and the mold plate 8, thereby improving the overall structural strength of the mold plate 8.

[0018] The working principle of the steel strand drawing machine provided by this utility model is as follows: When using the device to perform wire drawing operations on steel strands, the initial end of the steel wire is passed from left to right through the first circular hole on the left and right walls of the drawing shell 3, the second circular hole on the left and right walls of the lubrication box 4, and the drawing die 92 at the bottom of the device (the drawing diameters of the drawing dies 92 in the device are different). The initial end of the steel wire is then wound and fixed onto the take-up reel 19. When the initial end of the steel wire passes through the lubrication box 4, it passes under the two limiting rollers 5 inside the lubrication box 4. The limiting rollers 5 allow the steel wire passing through the lubrication box 4 to pass through the bottom of the lubrication box 4, facilitating the contact and lubrication of the lubricating powder inside the lubrication box 4 with the outer surface of the steel wire, which is conducive to subsequent wire drawing operations. Then, the machine is controlled... Switch 2 starts the servo motor 18, causing its output shaft to drive the take-up reel 19 to rotate, thereby performing wire drawing and winding operations. The wire drawing die 92 changes the wire diameter. When changing the wire drawing die 92 according to the required wire diameter after drawing, the operator turns the handwheel 17 to drive the worm gear 15 to rotate. During the rotation of the worm gear 15, the meshing connection causes the worm wheel 16 to drive the die plate 8 to rotate via the rotating shaft 7, thereby correspondingly changing the wire drawing die 92 within the die plate 8. During this process, the operator moves the scale groove 13 adjacent to the corresponding wire drawing die 92 to the closest vertical position to the scale groove 12, thereby accurately positioning the changed wire drawing die 92. Simultaneously, during the operation of the device, the vertical movement... The sliding engagement between the two reinforcing seats 11 and the annular groove 10 bears the horizontal pressure applied to the drawing die 92 during the wire passing through it, preventing the pressure from acting vertically along the drawing die 92 to the bearing connection between the rotating shaft 7 and the die plate 8, thereby improving the overall structural strength of the die plate 8. When replacing the worn drawing die 92 after a period of use, the rotating ring 942 is rotated to drive the annular frame 932 to rotate in the opposite direction via the rotating shaft 2 931. The annular frame 932 drives the corresponding locking rod 934 to rotate synchronously via the rotating shaft 3 933. During this process, the sliding connection between the guide groove 935 inside the locking rod 934 and the corresponding positioning rod 936 brings the locking rod 934 closer to the die plate. One end of each of the eight circles rotates clockwise around the corresponding pivot 933, causing the right side of the locking rod 934, away from the center of the mold plate 8, to slide and separate from the left side of the adjacent wire drawing mold 92. This releases the lateral insertion limit on each wire drawing mold 92, allowing all wire drawing molds 92 to be released in one step. The wire drawing mold 92 is then horizontally moved to the left from its corresponding mold housing 91 for removal and replacement. During this process, the torsion spring 943's rotational torque increases as the rotating ring 942 rotates counter-clockwise. After the wire drawing mold 92 is replaced, the operator releases the knob torque applied to the rotating ring 942. The reset torque of the torsion spring 943 causes the rotating ring 942 to rotate clockwise and reset via the pivot 931.The end of the locking rod 934 furthest from the center of the mold plate 8 is reset using the same principle. The right side of this end of the locking rod 934 furthest from the center of the mold plate 8 has an arc-shaped chamfer. This chamfer creates an initial lateral contact gap between the right side of the locking rod 934 furthest from the center of the mold plate 8 and the left side of the corresponding wire drawing die 92. Through this gap and the contact pressure applied by the arc-shaped chamfer, the right side of the locking rod 934 furthest from the center of the mold plate 8 can move towards the left side of the corresponding wire drawing die 92 while simultaneously applying a force to penetrate the wire drawing die 92 into the corresponding mold housing 91, thereby allowing the replaced wire drawing die 92 to... During the synchronous self-fixing operation, the positioning rod 95 limits the forward rotation of the ring frame 932 to prevent excessive rotation under the action of the torsion spring 943, which could cause the locking rod 93 to separate from the corresponding wire drawing die 92. After the device has been used for a period of time, the connecting frame 941, the rotating ring 942, and the torsion spring 943 between them should be completely removed and replaced (the connecting frame 941 is fixed to the left side of the die plate 8 by bolt 1, and the rotating ring 942 is fixed to the left end of the rotating shaft 931 by bolt 2), thus preventing the torsion spring 943 from aging after long-term use.

[0019] It is worth noting that the servo motor 18 disclosed in the above embodiments can be Y90S-2, and the control switch 2 is provided with a control button corresponding to the servo motor 18 for controlling its switching.
