Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing machines, and more specifically, to a single-station double-hook wire drawing machine and a wire drawing method thereof. Background Art

[0002] A wire drawing machine is a device designed to draw out steel wires for small car tires and engineering vehicle tires. Before shredding and recycling tires, it is necessary to pre-treat the tires to remove the thick steel wires that cannot be shredded by the shredding equipment to avoid damaging the shredding equipment. In the early days of the industry, the treatment of thick steel wires was to cut off the inner tube manually using a grinding machine. After removing the inner tube, the steel wires were taken out. With the development of the industry, the low efficiency of manual treatment led to the emergence of auxiliary equipment such as wire drawing machines. The principle of this type of equipment is to connect the pulling hooks through hydraulic means and pull out the bead.

[0003] For example, the utility model patent with the publication number CN220331697U discloses a single-hook wire drawing machine. The telescopic rod drives the slider to slide, and the sliding of the slider drives the pulling hook to stretch on both sides of the wire drawing groove. When the pulling hook is outside the housing, a tire is installed on the pulling hook, and the telescopic rod is used to drive the pulling hook to pull inward. During the pulling process, the shape of the wire drawing groove is used to pull out the steel wires inside the tire. This type of equipment has accelerated the processing efficiency compared to manual treatment and also meets the production capacity of the early-stage whole-line supporting in the industry. However, due to the upgrade of supporting equipment, the efficiency of the single-station wire drawing machine is relatively low and can no longer meet the supporting production capacity, so it needs to be upgraded and transformed.

[0004] Therefore, it is necessary to propose a single-station double-hook wire drawing machine and a wire drawing method thereof to at least partially solve the problems existing in the prior art. Summary of the Invention

[0005] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further detailed in the Detailed Description section. The Summary of the Invention section of the present invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0006] To at least partially solve the above problems, the present invention provides a single-station double-hook wire drawing machine, including:

[0007] A machine body, on which a lifting unit, a pulling hook feeding unit, a double-hook pulling hook, and a front baffle are provided. The front baffle is arranged on the front side of the machine body, and the tire is inclined against the front baffle at a preset angle; the lifting unit is used to lift the tire to the wire drawing position at the preset angle; the pulling hook feeding unit is arranged on the upper part of the machine body and is used to drive the double-hook pulling hook to move horizontally; two pulling hooks are provided on the double-hook pulling hook, and the two pulling hooks are respectively used to hook the inner steel wire and the outer steel wire of the tire.

[0008] Preferably, the double-hook pull hook includes:

The first notch is used for the outer steel wire to pass through, and the second notch is used for the inner steel wire to pass through.

[0012] Preferably, the aircraft trough plate includes two plate bodies arranged symmetrically left and right. The side where the two plate bodies are close to each other forms a pull hook channel, a first notch and a second notch. The side where the two plate bodies are far from each other is hinged to the front baffle.

[0013] Preferably, the lifting unit includes a lifting drive unit, a lifting platform and a positioning boss. The lifting drive unit is arranged on the front baffle.

[0014] Preferably, a guiding boss is arranged on the rear side of the front baffle for guiding the pulling path of the steel wire.

[0015] Preferably, the single-station double-hook steel wire pulling machine further includes a clamping unit and a cutting unit. The clamping unit is connected to the pull hook feeding unit. After the double-hook pull hook tightens the steel wire, the clamping unit clamps the steel wire and moves synchronously with the double-hook pull hook; the cutting unit is arranged on one side of the machine body for making an incision on the inner lip of the tire and cutting off the internal steel wire.

[0040] The following further describes the present invention in detail with reference to the drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0041] It should be understood that the terms such as "having", "including" and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0042] Embodiment 1:

[0043] As Figures 1-7 shown, the present invention provides a single - station double - hook wire pulling machine, including:

[0044] The machine body 1 is provided with a lifting unit 2, a hook feeding unit 3, a double-hook 4 and a front baffle 5. The front baffle 5 is arranged on the front side of the machine body 1, and the tire is inclined against the front baffle 5 at a preset angle; the lifting unit 2 is used to lift the tire to the wire pulling position at the preset angle; the hook feeding unit 3 is arranged on the upper part of the machine body 1 and is used to drive the double-hook 4 to move horizontally; two hooks are arranged on the double-hook 4, and the two hooks are respectively used to hook the inner wire and the outer wire of the tire.

[0045] The working principle and beneficial effects of the above technical solution are as follows:

[0046] The present invention provides a single-station double-hook wire pulling machine. When in use, first move the tire onto the lifting unit 2 so that the tire is inclined against the front baffle 5 at a preset angle; start the lifting unit 2 to lift the tire to the wire pulling position while maintaining the preset angle; the hook feeding unit 3 drives the double-hook 4 to move forward horizontally so that the double-hook 4 passes through the front baffle 5 and enters the tire bead; start the lifting unit 2 to descend and separate from the tire, and the tire falls onto the double-hook 4 while maintaining the preset angle. At this time, the double-hook 4 hooks the tire bead; then the hook feeding unit 3 drives the double-hook 4 to move backward horizontally, and the inner wire and the outer wire of the tire are respectively pulled out by the two hooks of the double-hook 4; during the wire pulling process, the front baffle 5 blocks the tire until the wire is completely pulled out.

[0047] Through the above structural design, the existing single-hook wire pulling method is changed to a double-hook wire pulling form. When the double-hook 4 retracts, the double-hook 4 synchronously hooks the inner and outer two strands of wires of the tire and retracts synchronously, realizing single-station double-hook wire pulling operation and improving the wire pulling efficiency; the improved double-hook 4 can also be directly used in a double-station wire pulling machine, and the efficiency is 4 times higher than that of a single-station single-hook.

[0048] Embodiment 2:

[0049] As Figure 2 shown, on the basis of the above Embodiment 1, the double-hook 4 includes:

[0050] A first hook 41 and a second hook 42. The first hook 41 is used to hook the inner wire of the tire, and the second hook 42 is used to hook the outer wire of the tire; a first inclined surface 43 is formed on the side of the first hook 41 away from the tire; a second inclined surface 44 is formed between the first hook 41 and the second hook 42, and a third inclined surface 45 is formed on the bottom surface of the second hook 42.

[0051] The hook tips of the first hook 41 and the second hook 42 form a first distance 46 in the horizontal direction, the bottom of the hook tip of the first hook 41 and the bottom of the hook tip of the second hook 42 form a second distance 47 in the vertical direction, and the second hook 42 and the end of the double-hook 4 close to the tire form a third distance 48 in the horizontal direction.

[0052] The working principle and beneficial effects of the above technical solution are as follows:

[0053] When the double-hook pull hook 4 moves backward, the first inclined surface 43 contacts the inner side of the tire, and the inner side of the tire enters the groove of the first pull hook 41. The tire forms a certain angle with the double-hook pull hook 4. When the first pull hook 41 hooks the inner steel wire, under the blocking action of the front baffle 5, the tire deforms as the steel wire is pulled out and is gradually folded into a > shape; the folded tire gradually retracts inward along the second inclined surface 44, and the outer side of the tire enters the groove of the second pull hook 42, and the outer steel wire is hooked by the second pull hook 42. The bottoms of the hook tips of the first pull hook 41 and the second pull hook 42 form a second distance 47 in the vertical direction. The function of the second distance 47 is to ensure that the two strands of steel wire will not interfere and break when being pulled out; the second pull hook 42 and the end of the double-hook pull hook 4 close to the tire form a third distance 48 in the horizontal direction. The function of the third distance 48 is to support the deformed tire and ensure that the path of the steel wire does not change, reducing the probability of the two strands of steel wire being entangled; the hook tips of the first pull hook 41 and the second pull hook 42 form a first distance 46 in the horizontal direction. The first distance 46 is matched with the tire size, so that when the inner steel wire is pulled out to make the tire in a > shape, the outer steel wire can be smoothly hooked by the second pull hook 42.

[0054] Embodiment 3:

[0055] As Figure 3 , Figure 5 shown, on the basis of the above Embodiment 1, an aircraft trough plate 6 is arranged on the outer side of the front baffle 5. The aircraft trough plate 6 includes a pull hook channel 61, a first notch 62 and a second notch 63. The pull hook channel 61 is arranged in the middle of the aircraft trough 6. The first notch 62 and the second notch 63 are arranged up and down and are spaced apart by a preset distance. The first notch 62 is used for the outer steel wire to pass through, and the second notch 63 is used for the inner steel wire to pass through.

[0056] The working principle and beneficial effects of the above technical solution are as follows:

[0057] The left and right sides of the first notch 62 are symmetrically arranged with respect to the pull hook channel 61, and the left and right sides of the second notch 63 are symmetrically arranged with respect to the pull hook channel 61; when the double-hook pull hook 4 pulls the inner and outer steel wires to move, the body of the double-hook pull hook 4 passes through the pull hook channel 61 on the aircraft trough plate 6, the pulled-out outer steel wire passes through the first notch 62, and the pulled-out inner steel wire passes through the second notch 63. The outer steel wire and the inner steel wire are guided through the first notch 62 and the second notch 63 so that they are pulled out along the preset track, reducing the risk of interference between the inner and outer steel wires.

[0058] Embodiment 4:

[0059] As Figure 5As shown in the figure, on the basis of the above-mentioned Embodiment 1, the aircraft channel plate 6 includes two plate bodies 64 that are symmetrically arranged left and right. One side of the two plate bodies 64 close to each other forms a hook channel 61, a first notch 62, and a second notch 63. One side of the two plate bodies 64 away from each other is hinged to the front baffle 5.

[0060] The working principle and beneficial effects of the above technical solution are as follows:

[0061] The aircraft channel plate 6 is set as two symmetrical plate bodies 64, and the two plate bodies 64 are connected to the front baffle 5 in a hinged opening and closing manner; when the two plate bodies 42 are closed, they can form a hook channel 61, a first notch 62, and a second notch 63. When pulling the steel wire, due to the pressure of the steel wire, they are closely attached to the front baffle 5 and will not unfold accidentally. When faults such as steel wire jamming, mating, and breaking occur, the two plate bodies 42 are opened from the middle to both sides, and the broken steel wire can be cleaned. Through the above structural design, a hinge opening and closing type combined aircraft channel structure is adopted, which can open the two plate bodies 42 from the middle, facilitating the cleaning of the broken steel wire and the maintenance and overhaul of the equipment.

[0062] Embodiment 5:

[0063] As Figure 3 shown in the figure, on the basis of the above-mentioned Embodiment 1, the lifting unit 2 includes a lifting drive unit 21, a lifting platform 22, and a positioning boss 23. The lifting drive unit 21 is arranged on the front baffle 5. The lifting platform 22 is slidably connected to the front side of the front baffle 5. The positioning boss 23 is connected to one side of the lifting platform 22 close to the front baffle 5. The bottom of the tire is placed on the lifting platform 22. The edge of the positioning boss 23 abuts against the inner side of the tire, and the top of the tire leans against the front baffle 5 obliquely.

[0064] The working principle and beneficial effects of the above technical solution are as follows:

[0065] The lifting drive unit 21 of the lifting unit 2 can be set as a chain-type lifting mechanism driven by hydraulic pressure and a motor. The lifting end of the lifting drive unit 21 drives the lifting platform 22 to perform lifting actions. During the process of pulling the steel wire, the lifting unit 2 is started to lift the tire to a preset position, which is slightly higher than the position of pulling the steel wire, so that the double-hook pull hook 4 can enter the tire bead without interference; after the double-hook pull hook 4 moves into place, the lifting unit 2 is started to descend and separate from the tire, and the tire can be hooked on the double-hook pull hook 4. The tire is placed on the lifting platform 2. The inner side of the bottom end of the tire abuts against the edge of the positioning boss 23, and the top of the tire leans against the front baffle 5. The positioning boss 23 is higher than the height of the lifting platform 22. Under the blocking action of the positioning boss 23, a preset distance is maintained between the bottom of the tire and the front baffle 5, facilitating the adjustment of the tire to a preset inclination angle.

[0066] Embodiment 6:

[0067] As Figure 4As shown, on the basis of the above-mentioned Embodiment 1, a guiding boss 9 is provided at the rear side of the front baffle 5 for guiding the pulling path of the steel wire.

[0068] The working principle and beneficial effects of the above technical solution are as follows:

[0069] A guiding boss 9 is provided at the rear side of the front baffle 5. The front-side steel wire and the rear-side steel wire are pulled out along a preset path under the guidance of the guiding boss 9, preventing the front-side steel wire or the rear-side steel wire from being joined together due to factors such as bending or breaking, and ensuring the normal operation of the steel wire pulling machine.

[0070] Embodiment 7:

[0071] As Figure 1 shown, on the basis of the above-mentioned Embodiment 1, a single-station double-hook steel wire pulling machine is characterized in that it further includes a clamping unit 7 and a cutting unit 8. The clamping unit 7 is connected to the hook feeding unit 3. After the double-hook pulling hook 4 tightens the steel wire, the clamping unit 7 clamps the steel wire and moves synchronously with the double-hook pulling hook 4; the cutting unit 8 is arranged on one side of the machine body 1 for cutting the inner lip of the tire and cutting off the internal steel wire.

[0072] The working principle and beneficial effects of the above technical solution are as follows:

[0073] When performing the steel wire pulling operation, the double-hook pulling hook 4 is used to hold the inner and outer steel wires of the tire. The hook feeding unit 3 drives the double-hook pulling hook 4 to move. After the steel wire is pulled out to a certain distance, the clamping unit 7 is started. The two clamping plates of the clamping unit 7 move to clamp the inner and outer steel wires simultaneously; then, under the pulling force of the double-hook pulling hook 4, the clamping unit 7 moves synchronously with the double-hook pulling hook 4 until the steel wire is completely pulled out. Through the setting of the clamping unit 7, the inner and outer steel wires can be clamped synchronously, preventing the steel wire from slipping and flying out during the pulling process, preventing the steel wire from slipping and being joined together, and improving the reliability and safety of the steel wire machine.

[0074] The cutting unit 8 is movably arranged on one side of the machine body 1. When encountering an engineering vehicle tire with a relatively thick steel wire and the double-groove pulling hook 4 cannot effectively pull it out, a notch can be cut in the inner lip of the tire using the cutting unit 8 to cut off the internal steel wire before pulling out the steel wire; effectively reducing the load of the power source of the hook feeding unit 3 and improving the adaptation range of the steel wire pulling machine.

[0075] Embodiment 8:

[0076] As Figure 3 shown, on the basis of the above-mentioned Embodiment 5, slopes 24 are provided on the left and right sides of the lifting platform 22, and two positioning rollers 25 are rotatably arranged in the middle of the lifting platform 22. The bottom of the tire is installed between the two positioning rollers 25.

[0077] The working principle and beneficial effects of the above technical solution are as follows:

[0078] When the tire moves to the lifting platform 22, the tire is rolled onto the lifting platform 22 through any one of the ramps 24 on the left and right sides. There is a hollow between the two positioning rollers 25, and the bottom of the tire is clamped between the two positioning rollers 25. The positioning rollers 25 can rotate to facilitate the adjustment of the relative position of the tire.

[0079] Embodiment 9:

[0080] As Figures 8-11 shown, on the basis of the above Embodiment 1, an automatic positioning unit is provided on the lifting platform 22. The automatic positioning unit includes:

[0081] A positioning groove 71 is provided at the center of the lifting platform 22. Slide rails 72 are provided on the front and rear sides of the positioning groove 71. A support block 73 is slidably connected to the slide rails 72. Both ends of the positioning roller 25 are rotatably connected to the support block 73;

[0082] A positioning seat 74 is connected to one side of the bottom end of the lifting platform 22;

[0083] A telescopic sliding sleeve 75 is connected to the positioning seat 74. The telescopic sliding sleeve 75 is arc-shaped and has a cavity in the middle. Both ends of the telescopic sliding sleeve 75 are open;

[0084] Two telescopic rods 76. One end of each telescopic rod 76 is slidably connected inside the telescopic sliding sleeve 75, and the other end extends out of the telescopic sliding sleeve 75 and is connected to the positioning roller 25. The telescopic rods 76 are arc-shaped, and a toothed plate 81 is provided on the side where the two telescopic rods 76 face each other;

[0085] A positioning rotating shaft 77 is rotatably connected to the center of the telescopic sliding sleeve 75, and the positioning rotating shaft 77 is vertically arranged. A torsion spring 78 is provided between the positioning rotating shaft 77 and the inner wall of the telescopic sliding sleeve 75;

[0086] A positioning gear 79 is installed on the positioning rotating shaft 77 and meshes with the toothed plates 81 of the two telescopic rods 76;

[0087] A worm 82 is connected to the top end of the rotating shaft 77;

[0088] A positioning clamping plate 83 is rotatably connected to the top end of the telescopic sliding sleeve 75 through a clamping plate shaft 84. A worm gear 85 is connected to the clamping plate shaft 84. The worm gear 85 is meshed and connected with the worm 22. A box body 86 for accommodating the worm gear 85 and the worm 82 is provided on the telescopic sliding sleeve 75;

[0089] A guide wheel 87 is provided on the inner wall of the telescopic sliding sleeve 75. The guide wheel 87 contacts the part of the telescopic rod 76 that does not have the toothed plate 81.

[0090] The working principle and beneficial effects of the above technical solution are:

[0091] Before placing the tire, the two positioning rollers 25 are not under force. Under the action of the coil spring 78, the two telescopic rods 76 contract inside the telescopic sliding sleeve 75. Under the action of the coil spring 78, the positioning rotating shaft 77 remains stable. Under the cooperation of the worm and worm gear drive and the rack and pinion drive, the telescopic rod 76 and the positioning roller 25 are kept stable. When the tire is placed on the lifting platform 22, the tire moves between the two positioning rollers 25. Under the action of the tire gravity, the two positioning rollers 25 move to both sides. The positioning roller 25 drives the support block 73 to slide along the slide rail 72, increasing the gap between the positioning rollers 25. When the positioning roller 25 moves, it can automatically adjust the position of the tire so that it is centered between the two positioning rollers 25. The positioning roller 25 drives the telescopic rod 76 to move, causing the telescopic rod 76 to extend from the telescopic sliding sleeve 75. The toothed plate 81 on the telescopic rod 76 meshes with the positioning gear 79 to drive the rotation of the positioning rotating shaft 77, and at the same time stores energy for the coil spring 78. The positioning rotating shaft 77 drives the worm 82 to drive, causing the worm gear 85 to rotate accordingly. The worm gear 85 drives the clamping plate shaft 84 to rotate, causing the positioning clamping plate 83 to rotate out of the lifting platform 22. The positioning clamping plate 83 presses the tire, causing the tire to closely adhere to the edge of the positioning boss 23, thereby positioning the bottom of the tire. The guide wheel 87 guides the moving path of the telescopic rod 76 to reduce the transmission gap. When the tire is separated from the positioning roller 25, the positioning clamping plate 83 automatically rotates and resets under the action of the coil spring 78 without interference.

[0092] Through the above structural design, under the action of the tire gravity, the positioning roller 25 moves. During the movement, it can automatically position to the center of the positioning roller 25, adjust the left and right positions of the tire, and achieve the positioning in the left and right directions. At the same time, the positioning clamping plate 83 is rotated to press the tire against the positioning boss 23, adjusting the position of the tire in the front and back directions to achieve its positioning in the front and back directions. It can automatically adjust the tire to the preset angle and preset position when the tire is placed. Compared with the manual adjustment method, the efficiency is higher and the accuracy is higher.

[0093] Embodiment 10:

[0094] As Figures 8-11 shown, on the basis of the above Embodiment 9, the automatic positioning unit further includes:

[0095] A ring 88, the ring 88 is rotatably connected to the bottom of the positioning roller 25, and the outer diameter of the ring 88 is smaller than the outer diameter of the positioning roller 25. The ring 88 is connected to the end of the telescopic rod 76 through a support rod. A space for accommodating the positioning seat 74, the telescopic sliding sleeve 75, the telescopic rod 76 and the positioning clamping plate 83 is provided at the bottom of the lifting platform 22, and the height of the positioning clamping plate 83 is lower than that of the positioning roller 25.

[0096] The working principle and beneficial effects of the above technical solution are:

[0097] A circular ring 88 is provided on the positioning roller 25. The circular ring 88 can rotate relative to the positioning roller 25, without hindering the rotation of the positioning roller 25, enabling the tire to flexibly fall between the two positioning rollers 25. Additionally, the circular ring 88 does not come into direct contact with the tire and does not rotate with the positioning roller 25, which can ensure the stable position of the telescopic rod 76.

[0098] Embodiment 11:

[0099] Based on any one of the above Embodiments 1 - 10, a single-station double-hook wire pulling method using the single-station double-hook wire pulling machine is characterized by including:

[0100] Move the tire onto the lifting unit 2, and the tire leans against the front baffle 5 at a preset angle.

[0101] Start the lifting unit 2 to lift the tire to the wire pulling position at a preset angle.

[0102] The hook feeding unit 3 drives the double-hook 4 to move forward horizontally, so that the double-hook 4 passes through the front baffle 5 and enters the tire bead.

[0103] Start the lifting unit 2 to lower and separate from the tire, and the double-hook 4 hooks the tire bead.

[0104] The hook feeding unit 3 drives the double-hook 4 to move backward horizontally, and the two hooks of the double-hook 4 respectively pull out the inner wire and the outer wire of the tire.

[0105] The front baffle 5 blocks the tire until the wire is completely pulled out.

[0106] The working principle and beneficial effects of the above technical solution are as follows:

[0107] A single-station double-hook wire pulling method using the single-station double-hook wire pulling machine has the technical effects of the above single-station double-hook wire pulling machine; it changes the existing single-hook wire pulling method to a double-hook wire pulling form. When the double-hook 4 retracts, the double-hook 4 synchronously hooks the inner and outer two strands of wires of the tire and retracts synchronously, realizing single-station double-hook wire pulling operation and improving the wire pulling efficiency; the improved double-hook 4 can also be directly used in a double-station wire pulling machine, and the efficiency is 4 times higher than that of a single-station single-hook.
