Description

Technical Field

[0001] The present invention relates to the technical field of wire coiling, and in particular to wire coiling equipment and a coiling process. Background Art

[0002] The wire drawing machine is a pre-processing equipment for the production of standard parts and other metal products. Its purpose is to process the wires or bars produced and transported by steel manufacturers to standard parts and other metal product manufacturers through the wire drawing machine, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wires or bars meet the raw material processing requirements for the production of standard parts and other metal products. The winding equipment is used in conjunction with the wire drawing machine. After the wire drawing machine turns the wire into the ideal wire diameter, the winding equipment will wind the wire for subsequent storage and transportation. The winding equipment consists of the power system, reel and other main mechanisms. It is suitable for the winding and bundling of cold-drawn steel bars and cold-rolled ribbed steel bars. It is equipped with a special combination control cabinet and is easy to operate.

[0003] For example, the invention patent with the authorization announcement number CN105945088B discloses a wire drawing machine, including a wire drawing machine body, a wire winding mechanism is provided in the middle of the wire drawing machine body, the wire winding mechanism includes a wire winding table, a motor driving the wire winding table to rotate, and a roller arranged on the outside of the wire winding table for clamping the wire. The wire winding table is kept rotating continuously by the motor during operation, and the wire is continuously collected, and the collected wire is wound on the wire winding table. The roller not only realizes the clamping space with the wire winding table, but also applies pressure to the wire to realize the compression of the wire and prevent the wire from falling during the process of being transmitted to the wire winding table and wound. A tray is provided at the lower end of the wire winding table, and the diameter of the tray is larger than the diameter of the wire winding table. The wire winding table contacts the wire and supports the wire through the tray. A circular wire take-up rack is provided under the wire reel. The axis line of the wire take-up rack is on the same straight line as the axis line of the wire reel. After the wires fall from the wire reel, they are collected on the wire take-up rack. At this time, the wire take-up rack can quickly transfer and transport the collected wires.

[0004] However, the above prior art also has the following disadvantages:

[0005] 1. The drum is fixedly connected to the wire drawing machine body. In order to allow the wound wire to fall onto the take-up rack, the distance between the outer diameter of the drum and the outer diameter of the tray must not be less than the diameter of the wire, that is, the distance between the outer diameter of the drum and the outer diameter of the wire coiling table must be greater than the diameter of the wire. The drum presses the wire during the winding process, which only limits the wire so that the wire coiling table can smoothly wind the wire, but cannot truly press the wire on the wire coiling table along the radial direction of the wire coiling table during winding. Therefore, it is difficult for the drum to effectively control the tension of the wire, and the wire is prone to loosening when it falls to the take-up rack after winding, resulting in poor winding effect of the wire.

[0006] 2. When the winding starts, the end of the wire passes through the gap between the wire coiling table and the roller, and is restricted by the roller in its displacement in the radial direction away from the wire coiling table to achieve winding. However, the roller cannot completely fix the end of the wire on the outer surface of the wire coiling table. On the one hand, it may cause the wire to fall off the wire coiling table when winding. On the other hand, it will cause a certain distance between the end of the wire and the winding starting point after winding. This part of the wire is not effectively wound, which will not only affect the overall winding rate of the wire, but also the part of the wire that is not wound will interfere with the placement and transportation of the wire after winding, so that each wire roll cannot be placed close to each other, occupying a large storage space. Summary of the invention

[0007] The present invention aims to provide a wire winding device and a winding process to solve the technical problems in the prior art that it is difficult to control the tension of the wire during the winding process, and the wire is prone to loosening after winding, resulting in poor winding effect.

[0008] In order to achieve the above object, the present invention adopts the following technical scheme:

[0009] The wire winding equipment comprises a frame and a wire drawing die, a winding roller, a wire take-up stand and a power unit installed on the frame. The power unit drives the winding roller to rotate. The winding roller is arranged horizontally. The winding roller comprises a wire drum and a transition drum which are coaxially and detachably connected. A lifting mechanism is arranged at the connection between the wire drum and the transition drum in the winding roller. A clamp is fixedly connected to the output end of the lifting mechanism. A lifting hole is provided at the position of the winding roller corresponding to the clamp. The wire take-up stand is located at one end of the transition drum away from the wire drum, the wire drawing die is located on one side of the wire drum, and the wire drawing die is horizontally rotatably connected to the frame. A swing arm is also hinged on the frame. A pressure roller is rotatably connected to the end of the swing arm. The axis of the pressure roller is parallel to the axis of the wire drum.

[0010] Compared with the existing technology, this solution has the following advantages:

[0011] 1. In actual use, the lifting mechanism drives the clamp to extend the winding roller from the lifting hole, and the end of the wire is clamped and fixed on the outer surface of the winding roller by the clamp, which can not only ensure the stability of the position of the wire end when the winding starts, and prevent the wire from falling from the winding roller, so as to ensure the smooth winding of the wire; but also ensure that the wire is wound from the end, and avoid that a certain length of wire between the actual winding starting point and the end of the wire is not wound, which causes the unwound wire to affect the stacking of the wire coils after winding, so that the space occupied by the wire coils is large, which is not convenient for storage and transportation.

[0012] 2. Rotate the wire drawing die horizontally and connect it to the frame. Before clamping and fixing the end of the wire on the fixture, rotate the wire drawing die to align with the fixture. The wire will be fixed by the fixture along the axial direction, and the wire will also be wound along the axial direction when it is wound. This can avoid the occurrence of folded corners when the wire is wound, ensure the smoothness of the wire winding, and thus improve the winding effect.

[0013] 3. A swing arm is hinged on the frame, and a clamping roller is rotatably connected to the end of the swing arm. The swing arm rotates relative to the frame to make the clamping roller approach the wire on the wire drum until the clamping roller contacts the wire and presses the wire onto the wire drum, so that the wire is rolled up against the outer wall of the wire drum to ensure that the inner diameter of the wire loop formed after the wire is rolled up is consistent with the outer diameter of the wire drum, thereby ensuring the uniformity of the winding of each part of the wire. In addition, the clamping roller presses the wire during the winding process, which can control the tension of the wire and ensure the continuity of the winding effect after the wire is wound up, avoiding loosening of the wire after winding, and further improving the winding effect of the wire.

[0014] 4. The wire drum and transition drum of the winding roller are designed to be detachably connected. When the lifting mechanism and clamp in the winding roller fail, the transition drum can be removed from the wire drum, which is convenient for inspection, repair and replacement of the lifting mechanism and clamp; and when one of the wire drum and transition drum is worn during long-term use and affects the wire winding effect, the worn wire drum or transition drum can be replaced specifically without replacing the entire winding roller, which is beneficial to reduce equipment replacement costs and thus control production costs.

[0015] 5. The winding roller is designed to be composed of a wire drum and a transition drum, and the clamp is arranged at the connection between the wire drum and the transition drum. Compared with the arrangement of the clamp on the wire drum corresponding to the position of the wire drawing die, although this solution requires the wire drawing die to be rotatably connected to the frame to ensure the continuity of the wire winding, this solution can avoid the wire being pressed by the pressing roller at the position of the lifting hole and damaged by the edges and corners of the lifting hole when the wire is subsequently compressed and wound by the pressing roller. This not only ensures the winding effect, but also ensures that the wire is not damaged during the winding process, thereby ensuring the quality of the wire.

[0016] Preferably, as an improvement, the take-up frame is arranged at an angle, the top of the take-up frame is aligned with the end of the transition cylinder away from the winding cylinder, and the bottom of the take-up frame is hinged on the frame.

[0017] In this solution, the take-up frame is tilted and the top of the take-up frame is aligned with the end of the transition drum away from the wire drum. Compared with the vertical setting of the take-up frame, the transition between the take-up frame and the transition drum in this solution is more gentle, which is conducive to ensuring that the coiled wire ring falls smoothly from the transition drum to the take-up frame for temporary storage. The tilted take-up frame can play a certain buffering role in the fall of the coiled wire ring, preventing the wire ring from being scattered due to the strong impact of the vertical fall. Since the bottom of the take-up frame is hinged on the frame, when the wire is wound and all falls on the take-up frame, the take-up frame can be rotated relative to the frame so that the take-up frame is in a vertical state, thereby facilitating the removal of the coiled wire ring from the take-up frame.

[0018] Preferably, as an improvement, the bottom of the take-up frame is rotatably connected to a chassis, and the chassis is hinged to the frame.

[0019] By adopting this solution, a chassis is provided at the bottom of the wire take-up frame, so that the chassis is hinged to the frame, and the chassis can be rotated relative to the frame to achieve the switching between the top of the wire take-up frame being aligned with the end of the transition cylinder and the wire take-up frame being in a vertical state; and the connection mode between the bottom of the wire take-up frame and the chassis is a rotating connection, so that the wire take-up frame can be driven to rotate continuously during the process of the wound wire loop falling from the transition cylinder to the wire take-up frame, so that the wire loop can be effectively maintained by the wire take-up frame during the process of sliding off and temporarily storing on the wire take-up frame to resist the tension of the wire, thereby ensuring the continuity of the winding effect of the wire loop.

[0020] Preferably, as an improvement, the end of the swing arm is rotatably connected to a plurality of pressing rollers to form a pressing roller group, and the axes of the pressing roller group are arranged in an arc shape.

[0021] By adopting this scheme, several pressing rollers are rotatably connected to the end of the swing arm to form a pressing roller group. Then, during the wire winding process, the wire being wound is pressed against the wire drum by the pressing roller group. Compared with a single pressing roller, the pressure area of ​​the wire can be increased, so that the wire can fit better on the wire drum, thereby improving the wire winding effect; and the axes of several pressing rollers in the pressing roller group are arranged in an arc shape. Then, when the wire is pressed against the wire drum, it can be ensured that each pressing roller is in full contact with the wire, thereby ensuring that each pressing roller can fully exert its pressing effect, further increasing the pressure on the wire to improve the wire winding effect.

[0022] Preferably, as an improvement, the number of the clamping roller groups is several, and the several clamping roller groups are arranged along the circumference of the wire drum.

[0023] By adopting this solution, a plurality of clamping roller groups are arranged along the circumference of the wire drum. Then, the parts of the wire drum where the wire is being wound and the parts where the winding is completed can be subjected to the clamping force from the clamping roller groups to ensure that all parts of the wire are tightly fitted on the wire drum. This is not only conducive to resisting the tension during the winding process of the wire, but also can further control the tension of the wire after winding, so that the winding effect of the wire can be effectively consolidated and the continuous winding effect of the wire can be improved.

[0024] Preferably, as an improvement, a plurality of protection strips are evenly arranged on the outer wall of the transition tube along the axial direction.

[0025] By adopting this solution, a plurality of protective strips are arranged on the outer wall of the transition tube along the axial direction, which can separate the wire loop and the transition tube, thereby preventing the wire loop from causing wear on the outer wall of the transition tube during the movement of the transition tube, which is beneficial to extending the service life of the transition tube and reducing the cost of equipment replacement; and the plurality of protective strips are evenly arranged, which can improve the uniformity of the protection of various parts of the transition tube by the protective strips, further ensuring the service life of the transition tube.

[0026] The wire coiling process, using the above-mentioned wire coiling equipment, includes the following steps:

[0027] S1: Alignment, horizontally rotate the wire drawing die so that the discharge port of the wire drawing die is aligned with the lifting hole;

[0028] S2: Fixing, the lifting mechanism drives the clamp to extend out of the surface of the winding roller, and clamps the end of the wire passing through the outlet of the wire drawing die on the clamp;

[0029] S3: Winding: the power unit drives the winding roller to rotate and winds the wire on the wire drum. The wire drawing die is pulled by the wire to face the wire drum. The swing arm rotates to make the pressing roller group contact the wire and press the wire on the wire drum. Then the clamp releases the end of the wire, and the lifting mechanism drives the clamp to retract into the winding roller.

[0030] S4: Wire rewinding: the wire being rewound pushes the completed wire onto the transition drum, and the wire falls onto the wire rewinding rack through the transition drum. The wire rewinding rack rotates on the chassis to maintain the wire rewinding, so as to reduce the increase in the wire reel diameter.

[0031] S5: Take the wire. After the wire is wound up, it all falls onto the take-up rack. The chassis rotates relative to the frame so that the take-up rack is in a vertical state. After the wire is taken out from the take-up rack, the chassis is reversed relative to the frame to return the take-up rack to its original position.

[0032] It should be noted that the coil diameter refers to the outer diameter of the wire coil formed after the wire is coiled.

[0033] Compared with the existing technology, this solution has the following advantages:

[0034] 1. Before winding, align the wire drawing die with the clamp, and start winding after the end of the wire extending from the wire drawing die is fixed by the clamp. During the winding process, the wire drawing die gradually rotates horizontally to face the wire drum under the pull of the wire. At this time, the wire is pressed against the outer surface of the wire drum by the clamping roller for winding. The clamp and the clamping roller are switched in sequence, which not only ensures the position stability of the wire end relative to the wire drum when winding starts, so that the winding can be carried out smoothly and start from the end of the wire, but also ensures the continuity of the wire winding, so that the wire is always wound along its own axis to avoid folding angles.

[0035] 2. After the wire is pressed on the wire drum by the clamping roller for winding, the clamp releases the end of the wire, and the lifting cylinder drives the clamp to retract from the lifting hole into the winding roller. At this time, there is no protruding clamp at the connection between the wire drum and the transition drum. The wire that has been wound near the end of the wire can be smoothly moved from the wire drum to the transition drum under the extrusion of the subsequent wire, and gradually squeezed from the transition drum to the take-up frame. Therefore, the wire drum can be continuously wound in conjunction with the clamping roller, and the wound wire can pass through the wire drum and the transition drum in turn and fall onto the take-up frame, realizing the continuous winding operation of the wire and improving the processing efficiency.

[0036] 3. Whether the clamp clamps the wire end to the outer surface of the wire drum, or the pressure roller presses the wire to the outer surface of the wire drum, it can ensure that the wire is rolled up close to the outer surface of the wire drum, so that the rolled wire has a consistent roll diameter, and the pressure of the pressure roller resists part of the tension of the wire, making the wire winding effect more stable, reducing the increase in the wire roll diameter after the winding is completed; and after the rolled wire falls onto the take-up frame, the take-up frame continues to rotate to maintain the winding of the wire, further preventing the wire loop from spreading, and playing a certain role in maintaining the winding effect of the wire; therefore, this scheme can continuously control the tension of the wire during the winding process and the wire winding process, reduce the increase in the outer diameter of the wire loop after winding, so as to maintain the wire roll diameter close to the expected roll diameter, thereby ensuring a good winding effect of the wire.

[0037] Preferably, as an improvement, the rotation speed of the take-up frame in step S4 is greater than the rotation speed of the take-up roller in step S3.

[0038] By adopting this solution, the rotation speed of the wire take-up frame is designed to be greater than the rotation speed of the winding roller. Then, the wire loop formed after the wire is wound on the winding roller will be driven by the wire take-up frame to continue rotating at a speed greater than the winding roller during the process of sliding onto the wire take-up frame and being temporarily stored on the wire take-up frame, so as to continue to tighten the wire loop, thereby preventing the wire loop from spreading on the wire take-up frame, which is beneficial to maintaining the winding effect of the wire loop.

[0039] Preferably, as an improvement, the outer diameter of the take-up frame in step S4 is 8 cm to 20 cm smaller than the outer diameter of the take-up roller in step S3.

[0040] By adopting this solution, the outer diameter of the wire take-up frame is designed to be 8cm to 20cm smaller than the outer diameter of the winding roller, which can ensure that the wire loop formed after winding can slide smoothly onto the wire rack for temporary storage, and can also make the wire loops neatly arranged in sequence on the wire take-up frame for subsequent use. If the size of the wire take-up frame is too large, that is, the difference in the outer diameters of the winding roller and the wire take-up frame is less than 8cm, the inner wall of the wire loop is easily damaged by friction with the wire take-up frame during the process of sliding on the wire take-up frame; if the size of the wire take-up frame is too small, that is, the difference in the outer diameters of the winding roller and the wire take-up frame is greater than 20cm, the wire loop is easy to shake relative to the wire rack during the process of the wire take-up frame rotating to keep the wire loop tight, resulting in the wire loop being unable to be neatly arranged along the axial direction of the wire take-up frame and tilting, and it is inconvenient to carry out subsequent bundling and stacking after the wire loop is taken out from the wire take-up frame.

[0041] Preferably, as an improvement, the outer diameter of the take-up frame in step S4 is 10 cm smaller than the outer diameter of the take-up roller in step S3.

[0042] By adopting this solution, the outer diameter of the wire take-up frame is designed to be 10 cm smaller than the outer diameter of the winding roller, so as to ensure that there is a relatively optimum distance between the outer wall of the wire take-up frame and the inner wall of the wire loop. On the one hand, it can ensure that the wire loop slides smoothly on the wire take-up frame without damaging the inner wall; on the other hand, it can prevent the wire loop from shaking excessively on the wire take-up frame, ensure that the wire loop is neatly arranged axially on the wire take-up frame, and prevent the wire loop from tilting and inconvenient for subsequent bundling operations, which is conducive to improving the overall efficiency of wire processing.

[0055] This embodiment also records a wire coiling process, using the above-mentioned wire coiling equipment, including the following steps:

[0056] S1: Alignment, horizontally rotating the wire drawing die 2 so that the discharge port of the wire drawing die 2 is aligned with the lifting hole 8;

[0057] Specifically, initially, the lifting hole 8 is located at the top of the winding roller 3, and the wire drawing die 2 is arranged along the radial direction of the winding roller 3. The wire is passed through the feed port of the wire drawing die 2, and the end of the wire is passed through the discharge port of the wire drawing die 2, and then the wire drawing die 2 is driven to rotate counterclockwise (with a rotation speed of 1000 rpm). Figure 4 At this time, the universal wheel 21 at the bottom of the drawing die 2 slides in the slide groove 22, guiding and limiting the rotation of the drawing die 2, and supporting the drawing die 2 to a certain extent, until the universal wheel 21 slides to the bottom end of the slide groove 22 (with the angle of view as the reference). Figure 4 The viewing angle is taken as a reference), at this time, the discharge port of the drawing die 2 is aligned with the fixture 7.

[0058] S2: Fixing, the lifting mechanism 6 drives the clamp 7 to extend out of the surface of the winding roller 3, and clamps the end of the wire passing through the discharge port of the wire drawing die 2 on the clamp 7;

[0059] Specifically, initially, since the lifting hole 8 is located at the top of the winding roller 3, the lifting mechanism 6 is in a vertical state. The lifting hydraulic cylinder 62 is started to drive the clamp 7 to move along the radial direction of the winding roller 3 until the clamp 7 extends out of the surface of the winding roller 3; then the end of the wire passing through the discharge port of the wire drawing die 2 is pulled to the clamping position, and the end of the wire is clamped and fixed.

[0060] S3: Winding: the power unit drives the winding roller 3 to rotate and winds the wire onto the wire drum 31. The wire drawing die 2 is pulled by the wire to face the wire drum 31. The swing arm 9 rotates to make the clamping roller 10 contact the wire and press the wire onto the wire drum 31. Then the clamp 7 releases the end of the wire, and the lifting mechanism 6 drives the clamp 7 to retract into the winding roller 3.

[0061] Specifically, the drive motor 5 is started to rotate the drive shaft 51, and the rotation of the drive shaft 51 drives the entire winding roller 3 to rotate. Since the end of the wire is clamped and fixed by the clamp 7, the wire will gradually be wound on the wire drum 31 as the winding roller 3 is wound, and will gradually be wound from the end of the wire drum 31 close to the clamp 7 to the end close to the drive motor 5; and since the wire drawing die 2 is rotatably connected to the frame 1, as the wire winding operation proceeds, the wire drawing die 2 will be gradually pulled by the wire to face the wire drum 31, that is, the wire drawing die 2 will gradually return to its initial position as the wire winding proceeds. At this time, the second hydraulic cylinder is started, and the second hydraulic cylinder drives the swing arm 9 to rotate relative to the frame 1, so that the clamping roller 10 contacts the wire and presses the wire on the wire drum 31, and then the clamp 7 is controlled to loosen the end of the wire, and the lifting hydraulic cylinder 62 is controlled to drive the clamp 7 to retract into the winding roller 3.

[0062] S4: winding, the wire being wound squeezes the wound wire onto the transition cylinder 32, and the wire falls onto the winding rack 4 through the transition cylinder 32. The winding rack 4 rotates on the chassis 11 to maintain the winding of the wire, so as to reduce the increase in the wire coil diameter;

[0063] Specifically, the wire continues to be wound on the wire drum 31. Due to the pressing and limiting effect of the pressing roller 10, the wire being wound will squeeze the wound wire from the wire drum 31 to the transition drum 32. At this time, the first motor is started, and the speed of the first motor is controlled to be greater than the speed of the driving motor 5. The motor drives the take-up frame 4 to rotate, and the speed of the take-up frame 4 is greater than the speed of the winding roller 3. The part of the wire that has been wound near the end of the wire is gradually squeezed from the transition drum 32 by the wire being wound and falls onto the take-up frame 4. During the process of the wire loop formed by the winding sliding on the take-up frame 4, it continues to be wound by the rotation of the take-up frame 4 with a faster speed, thereby maintaining the size of the wire loop, that is, reducing the increase in the wire coil diameter.

[0064] The outer diameter of the wire take-up frame 4 is 8 cm to 20 cm smaller than the outer diameter of the winding roller 3. Specifically, the outer diameter of the wire take-up frame 4 can be 8 cm, 10 cm, 15 cm, 20 cm, etc. smaller than the outer diameter of the winding roller 3. In this embodiment, the outer diameter of the wire take-up frame 4 is 10 cm smaller than the outer diameter of the winding roller 3. While minimizing damage to the inner wall of the wire loop, it can prevent the wire loop from shaking excessively on the wire take-up frame 4 and tipping over, resulting in subsequent removal and storage of the image.

[0065] S5: Take the wire. After the wire is wound up, it all falls onto the take-up rack 4. The chassis 11 rotates relative to the frame 1 so that the take-up rack 4 is in a vertical state. After the wire is taken out from the take-up rack 4, the chassis 11 is reversed relative to the frame 1 to return the take-up rack 4 to its original position.

[0066] Specifically, when the wire is wound, the drive motor 5 is turned off, the winding roller 3 stops rotating, and the second hydraulic cylinder is controlled to reset the swing arm 9, that is, the second hydraulic cylinder drives the clamping roller 10 to move away from the winding roller 3, and the wire will all fall onto the take-up frame 4. The first motor is turned off to stop the take-up frame 4 from rotating, and the first hydraulic cylinder is started to drive the connecting rod 13 to rotate relative to the support rod 14, that is, the chassis 11 is driven to rotate relative to the frame 1, so that the chassis 11 is in a horizontal state, that is, the take-up frame 4 is in a vertical state, so as to facilitate the removal of the wound wire from the take-up frame 4. After all the wires are taken out, the first hydraulic cylinder drives the chassis 11 to reset, that is, the take-up frame 4 returns to an inclined state, and the top of the take-up frame 4 is aligned with the end of the transition cylinder 32 away from the winding cylinder 31, so as to facilitate the next winding.
