Description

Technical Field

[0001] This utility model relates to the field of wire drawing equipment technology, specifically a continuous wire drawing machine for bare copper wire. Background Technology

[0002] A continuous drawing machine for bare copper wire is a piece of equipment used to produce bare copper wire. It stretches and processes copper wire through dies with different inner diameters, making the diameter of the bare copper wire change from thick to thin.

[0003] In existing technology, copper wire is drawn to a suitable size by passing it through a wire drawing machine and a die inside the machine.

[0004] However, in actual use, different stretching gaps are required for the production of copper wires of different specifications. If the distance between the drawing die ring and the roller at the input end is large, the tension on the side of the drawing die ring closer to the input end is prone to decrease during the drawing process, while the copper wire on the other side becomes tense. This results in a horizontal deviation between the part of the copper wire with reduced tension and the inner hole of the drawing die ring. During the process of being drawn into the drawing die ring, uneven stretching occurs in different parts, which affects the quality of the copper wire. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a continuous bare copper wire drawing machine. It solves the problem that in practical use, different drawing spacings are required for producing copper wires of different specifications. If the distance between the drawing die ring and the input roller is large, the tension on the side of the drawing die ring closer to the input end tends to decrease during the drawing process, while the copper wire on the other side becomes tense. This results in a horizontal deviation between the portion of the copper wire with reduced tension and the inner hole of the drawing die ring. Consequently, uneven stretching occurs in different parts during the drawing process, affecting the quality of the copper wire.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous drawing machine for bare copper wire, comprising a housing with openings on both sides, a mold block installed on the inner wall of the housing, a sleeve installed at the bottom of the mold block, a gear meshing with the bottom of the sleeve, a shaft fixedly connected to the inner wall of the gear, limit wheels provided on both sides of the inner wall of the housing, the outer wall of the shaft rotatably connected to the inner wall of the housing via a bearing, and a drive device installed on the outer wall of the gear.

[0007] Preferably, the driving device includes a worm gear, the outer wall of which is fixedly connected to the outer wall of a gear, a worm gear meshing with the outer wall of the worm gear, a servo motor fixedly connected to one end of the worm gear that passes through the housing via a bearing, the bottom of the servo motor being fixedly connected to the bottom of the housing, a bracket rotatably connected to the lower part of the outer wall of the worm gear via a bearing, the bottom of the bracket being fixedly connected to the bottom of the inner wall of the housing, and the servo motor being electrically connected to the control panel.

[0008] Preferably, a sliding rod is inserted into the inner wall of the sleeve, a fixing plate is fixedly connected to the outer wall of the sliding rod, and the outer wall of the fixing plate is fixedly connected to the inner wall of the box.

[0009] Preferably, a fixing shell is fitted onto one side of the outer wall of the mold block, and a positioning shell is fitted onto the other side of the outer wall of the mold block. The outer wall of the fixing shell is fixedly connected to the outer wall of the positioning shell by bolts, and the bottom of the positioning shell is fixedly connected to the top of the sleeve.

[0010] Preferably, the side of the box is provided with a sliding groove, the inner wall of the sliding groove is slidably engaged with an indicator rod, and the outer wall of the indicator rod is fixedly connected to the outer wall of the sleeve. Beneficial effects

[0011] This utility model provides a continuous bare copper wire drawing machine. It has the following advantages: Through the cooperation of a drive device, gears, and shafts, the drive device rotates the gears, and the meshing between the gears and the sleeve adjusts the position of each die block, thus stabilizing the copper wire during drawing. This solves the problem that during the drawing process, the tension on the side of the drawing die ring near the input end tends to decrease, while the copper wire on the other side remains tense. This leads to a horizontal deviation between the part of the copper wire with reduced tension and the inner hole of the drawing die ring, resulting in uneven stretching in different parts during the drawing process, thus affecting the quality of the copper wire.

[0012] By using the combination of the fixed shell, the positioning shell, and the mold block, when producing different types of copper wire, the fixed shell and the positioning shell are disassembled, and the corresponding mold block is installed between the fixed shell and the positioning shell. This makes it more convenient to produce different types of copper wire and solves the problem of inconvenience when changing molds of different types in the existing technology.

[0015] 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.

[0016] In practical applications, different drawing gaps are required for the production of copper wires of different specifications. If the distance between the drawing die ring and the roller at the input end is large, the tension on the side of the drawing die ring closer to the input end is prone to decrease during the drawing process, while the copper wire on the other side becomes tense. This results in a horizontal deviation between the part of the copper wire with reduced tension and the inner hole of the drawing die ring. During the process of being drawn into the drawing die ring, uneven stretching occurs in different parts, thus affecting the quality of the copper wire.

[0017] In view of this, the present invention provides a continuous drawing machine for bare copper wire, which solves the problem that in actual use, different drawing gaps are required for the production of copper wires of different specifications. If the distance between the drawing die ring and the roller at the input end is large, the tension on the side of the drawing die ring closer to the input end is prone to decrease during the drawing process, while the copper wire on the other side is stretched. This results in a horizontal deviation between the copper wire with reduced tension and the inner hole of the drawing die ring. During the process of being drawn into the drawing die ring, uneven stretching occurs in different parts, thus affecting the quality of the copper wire.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Example 1: By Figure 1-4It is known that a continuous drawing machine for bare copper wire includes a housing 1, with openings 3 on both sides of the housing 1, a mold block 5 installed on the inner wall of the housing 1, a sleeve 6 installed at the bottom of the mold block 5, a gear 9 meshing with the bottom of the sleeve 6, a shaft 18 fixedly connected to the inner wall of the gear 9, limit wheels 4 provided on both sides of the inner wall of the housing 1, the outer wall of the shaft 18 being rotatably connected to the inner wall of the housing 1 through a bearing, and a drive device installed on the outer wall of the gear 9. In the specific implementation process, it is worth noting that the mold block 5 is used to pull the copper wire. Multiple mold blocks 5 are provided, depending on the actual situation, to facilitate the production of copper wire. During wire pulling, the openings 3 on both sides of the box 1 are used to ensure that the copper wire enters. Grooves are provided on the surface of the limiting wheel 4 to ensure that the copper wire moves stably within the box 1. At the same time, the gear 9 is driven by the drive device to rotate, which makes it easy to adjust the distance between the mold blocks 5. When the copper wire is being pulled, the cover plate on the top of the box 1 is opened, and the copper wire is passed through the opening 3 on one side of the box 1, through the limiting wheel 4, and through multiple mold blocks 5. Then, it passes through the limiting wheel 4 and the opening 3 on the other side, and the copper wire is fixed on the traction device for pulling (or the limiting wheel 4 on the traction end side is connected to a power device, such as a servo motor, and used as a traction device for copper wire pulling by clamping). The copper wire is pulled into a wire. When changing the mold block 5, the cover plate on the top of the box 1 is opened for replacement. Furthermore, the drive device includes a worm gear 16, the outer wall of which is fixedly connected to the outer wall of the gear 9, a worm 17 meshing with the outer wall of the worm gear 16, a servo motor 10 fixedly connected to one end of the worm 17 through a bearing, the bottom of the servo motor 10 fixedly connected to the bottom of the housing 1, a bracket 15 rotatably connected to the lower part of the outer wall of the worm 17 through a bearing, the bottom of the bracket 15 fixedly connected to the bottom of the inner wall of the housing 1, and the servo motor 10 electrically connected to the control panel 2. In the specific implementation process, it is worth noting that since the worm gear 16 is fixed on the outer wall of the gear 9, and when the worm 17 meshes with the worm gear 16, it will drive the worm gear 16 to rotate. Moreover, the operator can control the servo motor 10 to rotate through the control panel 2. This makes the adjustment of the position of the mold block 5 more accurate. At the same time, the self-locking function between the worm 17 and the worm gear 16 prevents the position of the mold block 5 from being fixed after adjustment and prevents it from shaking during the wire drawing process. The model of the servo motor 10 is not limited, as long as it meets the actual use conditions. Furthermore, a sliding rod 8 is inserted into the inner wall of the sleeve 6, and a fixing plate 7 is fixedly connected to the outer wall of the sliding rod 8. The outer wall of the fixing plate 7 is fixedly connected to the inner wall of the box 1. In the specific implementation process, it is worth noting that the outer wall of the slide rod 8 is a smooth surface, which can reduce the friction between the slide rod 8 and the sleeve 6 when the sleeve 6 moves. Moreover, with the support of the fixed plate 7 and the slide rod 8, the sleeve 6 and other devices are stable when moving.

[0020] Example 2: From Figure 1-4 It can be seen that a fixing shell 13 is sleeved on one side of the outer wall of the mold block 5, and a positioning shell 14 is sleeved on the other side of the outer wall of the mold block 5. The outer wall of the fixing shell 13 is fixedly connected to the outer wall of the positioning shell 14 by bolts, and the bottom of the positioning shell 14 is fixedly connected to the top of the sleeve 6. In the specific implementation process, it is worth noting that a slot is provided on the side where the fixed shell 13 and the positioning shell 14 are close to each other, so that the mold block 5 can be inserted between the fixed shell 13 and the positioning shell 14. When the two are fixed together, the mold block 5 will be clamped in the middle, making it stable when the copper wire is pulled. Furthermore, a sliding groove 11 is provided on the side of the box 1, and an indicator rod 12 is slidably engaged with the inner wall of the sliding groove 11. The outer wall of the indicator rod 12 is fixedly connected to the outer wall of the sleeve 6. In the specific implementation process, it is worth noting that when the sleeve 6 moves, it will drive the indicator rod 12 to move on the inner wall of the slide 11. This ensures that the staff can know the position of the mold block 5 at any time. At the same time, a scale can be set on the side of the box 1 so that the staff can accurately adjust the position of the mold block 5.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
