Description

Technical Field

[0001] This invention belongs to the field of wire drawing machine equipment, specifically relating to an online adjustable zinc wire drawing machine. Background Technology

[0002] Zinc raw materials need to be drawn to form finished zinc wires of the required diameter. Zinc raw materials are generally wound on a reel. During the unwinding process of the existing wire unwinding mechanism, as the zinc material on the reel is gradually unwound, the diameter of the wound zinc material gradually decreases. If the speed of the unwinding shaft of the unwinding mechanism is not adjusted in time, the zinc material may become excessively loose, and there is a probability of a locking phenomenon, that is, the loose zinc material ring becomes entangled with the zinc material being unwound, resulting in the inability to unwind normally.

[0003] Because the wire drawing device is still feeding wire, if a locking phenomenon occurs, the machine needs to be stopped immediately and the locking needs to be manually removed. Otherwise, the forced wire drawing and feeding will cause the locking point to break due to the mutual pressure of the zinc material. The subsequent zinc material reconnection work will lead to a decrease in production efficiency. Currently, the wire feeding device and the wire drawing device are directly connected, and the length of zinc material that can be accommodated between the two is short. Even if the machine is stopped in time, the subsequent unlocking is also difficult because the wire drawing device cannot unload the material. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides an online adjustable zinc wire feeding and drawing machine, which adds an adjustment support device between the feeding device and the drawing device, and can provide online adjustment and buffering for zinc wire feeding.

[0005] The specific technical solution adopted in this invention is as follows: An online adjustable zinc wire feeding and drawing machine includes a frame and a wire drawing device and a wire feeding device mounted on the frame. The wire feeding device includes a wire feeding shaft, on which a zinc wire roll is placed. The wire feeding shaft rotates with the feeding of the wire drawing device. An adjustment support device is added to the frame. The adjustment support device includes a column mounted on the frame, a cantilever rod, and a support wheel rotatably mounted at the end of the cantilever rod. The two rims of the support wheel are arc-shaped and open outward. The middle part of the support wheel forms a slit-shaped zinc wire support channel through the rims. The support wheel is positioned between the wire output end of the wire feeding device and the wire input end of the wire drawing device. The support wheel has a degree of freedom of rotation relative to the cantilever rod.

[0006] The aforementioned adjustment support device is provided in at least two sets, and the cantilever rod is an elastic flexural rod with bending freedom.

[0007] The support wheel is positioned at a height higher than the wire inlet of the wire drawing device, and the zinc material exerts pressure on the support wheel during transport.

[0008] The wire drawing device includes two sets of return rollers and a drawing frame between the return rollers. The drawing frame is equipped with a drawing die. The zinc material is spirally wound around the two sets of return rollers and passes through a drawing die for each turn. The return rollers are equipped with multiple sets of return wheels, and the diameter of the return wheels is arranged in a gradient increasing manner.

[0009] The drawing device also includes a take-up shaft mounted on the frame, which is located on the output side of the return roller.

[0010] The wire feeding device is also equipped with a wire pressing shaft, which is located on one side of the wire feeding shaft. The zinc material led out from the zinc material coil passes around the wire pressing shaft, i.e., the support wheel, and is then fed into the wire inlet of the wire drawing device.

[0011] The elasticity of adjacent cantilever rods in the adjustment support device is set in a gradient, with the elasticity of the cantilever rod closer to the wire feeding end of the wire feeding device being greater than that of the cantilever rod farther away.

[0012] The column is a hollow structure and is fitted with a lifting column. The lifting column has the freedom to rise and fall relative to the column by means of a hydraulic lifting cylinder. The fixed end of the cantilever rod is fixed to the upper end of the lifting column.

[0013] The beneficial effects of this invention are: This invention utilizes an adjustable support device and a support wheel on the device to lift the zinc material, extending its conveying path and providing a buffer distance for potential locking. With the support of a cantilever rod, when locking occurs and the tension on the zinc material increases, the rod elastically deforms, causing the zinc material to deviate from its original conveying trajectory and rub against the rim of the support wheel. This distributes the tension at the locking point, preventing direct breakage of the zinc material and allowing time and space for shutdown and subsequent unhooking, thus improving the efficiency of wire drawing production.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Specific implementation examples Figure 1As shown, the present invention is an online adjustable zinc wire feeding and drawing machine, including a frame 1 and a wire drawing device and a wire feeding device mounted on the frame 1. The wire feeding device includes a wire feeding shaft 2, and a zinc wire roll 3 is placed on the wire feeding shaft 2. The wire feeding shaft 2 rotates with the feeding of the wire drawing device. An adjustment support device is added to the frame 1. The adjustment support device includes a column 4 mounted on the frame 1, a cantilever rod 5, and a support wheel 6 rotatably mounted at the end of the cantilever rod 5. The two sides of the support wheel 6 are arc-shaped and open outward. The middle part of the support wheel 6 forms a slit-shaped zinc wire support channel by means of the wheel rim. The support wheel 6 is located between the wire output end of the wire feeding device and the wire input end of the wire drawing device. The support wheel 6 has a degree of freedom of rotation relative to the cantilever rod 5.

[0016] In this invention, the zinc wire roll 3, after being unpacked, is hoisted onto the wire feeding shaft 2. Then, the wire feeding shaft 2 is started and rotated slightly to release a certain length of zinc wire. The new zinc wire is welded to the old zinc wire and then polished before continuing wire drawing production. When winding new zinc wire, the new zinc wire needs to pass through an additional adjusting support device, allowing the zinc wire to pass through the middle of the support wheel 6, forming a slit-like zinc wire support channel with the help of the wheel rim. During normal use, due to the small tension of the zinc wire, the support rod basically maintains a cantilevered, approximately horizontal state. The adjusting support device is provided in at least two sets, and the cantilever rod 5 is an elastic flexural rod with bending freedom. When the locking phenomenon occurs, the tension of the zinc material increases, and the cantilever rod 5 made of spring steel bends, causing the support wheel 6 to change from a vertical state to an inclined state. At this time, the zinc material naturally rests on the rim from the middle of the support wheel 6, and the rim is arc-shaped to avoid cutting the zinc material. At the same time, the zinc material contacts the side of the rim, and the friction between the zinc material and the rim is generated by the pressure of the zinc material itself, thereby distributing the tension of the zinc material on the locking node and preventing the zinc material from being torn apart.

[0017] The wire drawing device has a rectangular frame structure at the wire inlet. The zinc material passes through the inside of the rectangular frame. There are rollers arranged vertically along the horizontal and vertical directions on the side of the rectangular frame. The rollers support the zinc material and prevent the zinc material from rubbing directly against the rectangular frame.

[0018] The present invention is as follows Figure 1 and Figure 2 As shown, multiple sets of adjustable support devices can be set according to the existing frame 1 size, and the elasticity of the adjacent cantilever rods 5 of the adjustable support devices is set in a gradient, with the elasticity of the cantilever rod 5 on the side closer to the wire feeding end of the wire feeding device being greater than the elasticity of the cantilever rod 5 on the side farther away.

[0019] By setting multiple sets of cantilever rods 5, the cantilever rods 5 on the front and rear support discs 6 are bent to different degrees, thereby avoiding large displacement of the zinc material near the locking point, and preserving a certain length of wire for subsequent unlocking. On the side near the wire drawing device, the cantilever rod 5 has less elasticity and is more prone to bending, so that the wire drawing device still has a large length of wire available for production after the locking problem occurs, leaving sufficient time for personnel to discover and stop the machine. In addition, the multiple sets of cantilever rods 5 can distribute the tension of the wire drawing feed in stages, preventing stress concentration in one place and causing accidental breakage of the zinc material outside the locking point.

[0020] Furthermore, the support wheel 6 is positioned at a height higher than the wire inlet end of the wire drawing device, so that the zinc material exerts downward pressure on the support wheel 6 during transport. Figure 1 As shown, the wire feeding device is also equipped with a pressure shaft 10, which is located on one side of the wire feeding shaft 2. The zinc material led out from the zinc material spool 3 passes around the pressure shaft 10, i.e., the support wheel 6, and is then fed into the wire inlet of the wire drawing device. The support wheel 6 is as follows: Figure 1 As shown, the height of the support wheel 6 is higher than that of the wire-pressing shaft 10 and the wire-drawing device, so that the support wheel 6 is supported at a high position by the column 4, thereby leaving space for the elastic deformation of the cantilever rod 5.

[0021] The pressure shaft 10 is also provided with guide plates with a trumpet-shaped structure on both sides. The zinc material is constrained on the pressure shaft 10 by means of the guide plates, so as to ensure that the zinc material can be smoothly drawn out.

[0022] Furthermore, the wire drawing device includes two sets of return rollers 7 and a drawing frame 8 between the return rollers 7. The drawing frame 8 is equipped with a drawing die. The zinc material is spirally wound around the two sets of return rollers 7 and passes through a drawing die for each turn. The return rollers 7 are equipped with multiple sets of return wheels, and the diameter of the return wheels is arranged in a gradient increasing manner.

[0023] The wire drawing device of the present invention uses two sets of return rollers 7 to set multiple return wheels, so that the zinc material can be wound back and forth in a short distance and pulled back and forth multiple times in a small space. This allows thicker zinc material to be deformed on a larger scale in one step to form a thinner zinc wire, thereby improving production efficiency and reducing the equipment footprint.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, the drawing device also includes a take-up shaft 9 mounted on the frame 1, which is located on the output side of the return roller 7. The drawn zinc wire can be directly wound up via the take-up shaft 9 without the need for external equipment, enabling the storage and packaging of zinc wire products and further saving floor space.

[0025] Furthermore, the column 4 is a hollow structure and is fitted with a lifting column 11. The lifting column 11 has the freedom to rise and fall relative to the column 4 via a hydraulic lifting cylinder. The fixed end of the cantilever rod 5 is fixed to the upper end of the lifting column 11. When replacing with new zinc material, the lifting column 11 can be raised, causing the cantilever rod 5 and the support wheel 6 to rise and avoid interference. After the new zinc material reel 3 is hoisted, the lifting column 11 is lowered, the zinc material is wound onto the support wheel 6, and the wire is connected. After the wiring is completed, the lifting column 11 is raised again, and the drive motor of the pay-off shaft 2 is reduced in speed or temporarily locked, so that the support wheel 6 tensions the zinc material. Then the pay-off shaft 2 and the wire drawing device are started to start normal wire drawing production. When it is necessary to continue to deal with the locking problem, the lifting column 11 fitted on the column 4 can be lowered to provide additional wire length support for the disassembly of the locking, providing convenience for the staff and helping to resume production.
