Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing machines, and particularly to a wire drawing device and process for producing prestressed materials for railway sleepers. Background Art

[0002] Railway sleepers (commonly known as sleepers or railroad ties) play a crucial role in the railway system. The main function of sleepers is to support and fix the rails and evenly distribute the load from the train to the roadbed. According to the different materials, sleepers are mainly divided into the following types: wooden sleepers, concrete sleepers, steel sleepers, and composite material sleepers.

[0003] Among them, the concrete sleepers contain high-strength metal wires or steel strands inside. These metal wires are used to apply prestress to improve the bending resistance and durability of the sleepers. The metal wires are usually processed into specified specifications by existing wire drawing equipment before use.

[0004] However, during the process of processing metal wires using existing wire drawing equipment, due to the extrusion and friction of the die, part of the impurity particles will fall off from the worn metal wires. These particulate impurities accumulate in large quantities near the die, resulting in an increase in the friction force when the metal wires pass through the die. In this case, the metal wires are prone to breakage when being pulled. The broken metal wires swing around, which may cause harm to the nearby operators; if the broken metal wires wind around other components, it may also cause damage to the wire drawing equipment.

[0039] The turbine is fixedly connected to the fixing frame.

[0040] A wire drawing process for producing prestressed materials for railway sleepers, based on the above-mentioned wire drawing equipment for producing prestressed materials for railway sleepers, includes the following steps:

[0041] S1: firstly rotate the rotating frame, place the metal wire between the guide wheel connected to the rotating frame and the guide wheel connected to the sliding frame, then pull the metal wire through the first fixed shell, the guide shell, the mold core and the first rotating shell, and then wind the metal wire onto the traction unit to complete the pre-installation of the metal wire;

[0042] S2: After the metal wire is pre-installed, the traction unit, the material guide unit, the motor and the gas conveying unit are started, wherein the traction unit works to pull the metal wire through the die core, and the material guide unit works to convey the lubricating oil stored in the storage tank into the material guide shell and adhere to the metal wire;

[0043] S3: During the movement of the metal wire, the motor works to rotate the first rotating shell and the second rotating shell together through the connected parts, wherein the first rotating shell drives the inclined blades to rotate to guide the gas flow, and the second rotating shell rotates to drive the spiral blades to rotate to drive the lubricating oil in the guide shell to flow;

[0044] S4: During the movement of the metal wire, the gas delivery unit works to make the gas in the first nozzle and the second nozzle blow the lubricating oil at the mold core to flow, and the excess lubricating oil flows into the first fixed shell. When a certain amount of lubricating oil accumulates in the first fixed shell, the lubricating oil will lift the sliding baffle to move upward, and then the lubricating oil will enter the storage tank through the guide shell. During this process, the filter screen on the filter frame intercepts impurities such as particulate impurities in the lubricating oil, and at the same time, the lubricating oil impacts the turbine, and the fixed frame and the filter frame rotate together;

[0045] S5: After the lubricating oil is drained, the sliding baffle is reset by gravity, and then the lubricating oil is accumulated in the first fixed shell, and then the above-mentioned diversion operation is repeated to circulate the lubricating oil;

[0046] S6: During the processing of metal wire, when the metal wire breaks, the rotating frame drives the guide wheel on it to rotate and bend the metal wire due to the torsion force of the torsion spring connected to the rotating frame, so that the guide wheel on the rotating frame fits with the guide wheel under the rotating wheel on the same side to squeeze and bend the metal wire. The rotating frame rotates and the swing rod swings to fit the rotating wheel. At this time, the guide wheel connected to the rotating wheel cannot rotate, thereby completing the clamping of the metal wire.

[0047] Beneficial effects: The present invention bends and clamps the broken metal wire by swinging the rotating frame, so as to avoid the metal wire from breaking and injuring nearby operators, and to avoid the metal wire from being entangled on other parts and causing damage to the wire drawing equipment, thereby improving the safety and stability of the device; the inclined blades of the first rotating shell are used to rotate to pre-cool the metal wire after drawing, so as to avoid deformation or breakage that may occur during subsequent processing or use; the lubricating oil is guided by the guide shell and driven by the spiral blades to form a lubricating oil film of uniform thickness on the outside of the metal wire, which significantly reduces the wear on the mold core and the surface of the metal wire, and can also ensure that the wire is subjected to consistent pressure distribution when passing through the mold core, thereby reducing scratches and other surface defects; the first nozzle and the second nozzle are used to spray air to blow the mold core, so as to reduce the amount of granular impurities accumulated near the mold core and improve the quality of the final metal wire product; the lubricating oil is recycled by the diversion of the guide shell, thereby improving the resource utilization rate of the lubricating oil.

DETAILED DESCRIPTION

[0059] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0060] Embodiment 1: A wire drawing device for producing prestressed materials for railway sleepers, such as Figures 1-4 As shown, it includes: an operating table 1, the operating table 1 is equipped with a traction unit 11 and a first fixed shell 12, the first fixed shell 12 is fixedly connected to a fixed seat 121, and the fixed seat 121 is equipped with a mold core 122; a storage tank 13 is installed on the operating table 1 and is equipped with a material guide unit 131, and the material guide unit 131 is used to guide the lubricating oil stored in the storage tank 13 to the processed metal wire; a fixed rod 14 is fixedly connected to the first fixed shell 12, and the fixed rod 14 is provided with a sliding frame 10 in a limited sliding manner 5. The sliding frame 15 is rotatably provided with a rotating frame 16, a torsion spring is installed between the sliding frame 15 and the rotating frame 16, and the sliding frame 15 and the rotating frame 16 are both rotatably provided with a guide wheel 17, the rotating frame 16 is fixedly connected with a swing rod 18, and the guide wheel 17 on the sliding frame 15 is fixedly connected with a rotating wheel 19. When the swing rod 18 contacts the rotating wheel 19, the swing rod 18 restricts the rotating wheel 19 from rotating; an adjusting mechanism is arranged on the first fixed shell 12, and the adjusting mechanism is used to control the sliding frame 15 to move on the fixed rod 14.

[0061] like Figure 3 As shown, the adjustment mechanism includes: a rack 2 fixed to the first fixed housing 12; a spur gear 21 fixed to the rotating frame 16 and meshing with the rack 2.

[0062] In the above solution: There are three guide wheels 17 in the figure. The three guide wheels 17 are respectively located at the left and right parts of the sliding frame 15 and the left part of the rotating frame 16. Among them, the guide wheel 17 on the rotating frame 16 is located in the middle of the two guide wheels 17 on the sliding frame 15. In the state of the three guide wheels 17, the guide wheel 17 on the sliding frame 15 close to the rotating frame 16 is fixedly connected with a runner 19 (the guide wheel 17 can also be two, and the guide wheel 17 on the sliding frame 15 close to the first fixed shell 12 is removed, and the quantity is installed and set according to actual needs). The operating platform 1 is provided with a control terminal, and the control terminal is electrically connected to all the electrical components of this device. The traction unit 11 is provided with a load detection component. When the traction unit 11 is working and transporting metal wire, when the value of the load detection component on the traction unit 11 is small, it indicates that the metal wire is broken or the metal wire slips, and the traction unit 11 will stop working. In the figure, the fixed rod 14, the sliding frame 15, the rotating frame 16, the guide wheel 17, the swing rod 18 and the runner 19 are a group, and this group of structures is used to protect the metal wire on both sides of the die core 122 from breaking. On the left and right sides of the first fixed shell 12 in the attached drawing, a group of anti-breaking protection structures are provided, and the corresponding number of groups can be installed according to actual needs during actual use. The swing rod 18 is provided with a rubber pad, the runner 19 is provided with barbs, and the rubber pad on the swing rod 18 is in contact with the barbs on the runner 19 to limit the rotation of the runner 19 and the adjacent guide wheel 17, and complete the clamping of the broken metal wire to prevent it from accidentally touching the operator or damaging the equipment. The guide wheel 17 is provided with an annular groove for accurately moving the metal wire straight, and at the same time controlling the metal wire to pass through the middle of the die core 122. Rubber sheets are slidably arranged at the annular groove of the guide wheel 17 and are circumferentially distributed to increase the friction between it and the metal wire.

[0063] Specific working principle: In the initial state, the torsion spring connected to the rotating frame 16 is in a twisted state. At this time, the guide wheel 17 on the rotating frame 16 is in contact with the guide wheel 17 connected to the runner 19. When performing wire drawing operation on the metal wire, the operator first rotates the rotating frame 16 and twists the connected torsion spring. The swinging of the rotating frame 16 drives the spur gear 21 to rotate. The spur gear 21 rotates along the rack 2, that is, the sliding frame 15 drives the connected parts to move along the fixed rod 14. Then the operator pulls the metal wire through between the rotating frame 16 and the sliding frame 15, and then releases the rotating frame 16. Under the action of the torsion of the torsion spring connected to the rotating frame 16, the rotating frame 16 swings in the reverse direction to reset, so that the guide wheel 17 on it presses the metal wire, and the metal wire is in contact with the two guide wheels 17 on the sliding frame 15. After that, the operator passes the metal wire through the first fixed shell 12 and the die core 122, and makes the metal wire located between the guide wheels 17 on a group of rotating frames 16 and sliding frames 15 again.

[0064] After the metal wire passes through the first fixed housing 12, the operator winds the metal wire around the traction unit 11 to complete the pre-installation of the metal wire. When pre-installing the metal wire, according to the specifications of the processed metal wire required, a plurality of operating platforms 1 are placed in series, and the diameter specifications of the die cores 122 installed on the plurality of operating platforms 1 are arranged in decreasing order. Then, the above operations are repeated to enable the metal wire to pass through the die cores 122 on the plurality of operating platforms 1 in sequence, so that the diameter specification of the metal wire becomes the required state.

[0065] After the pre-installation of the metal wire is completed, the operator sends a signal to the control terminal on the connected operating platform 1 through the remote control system. The control terminal on the operating platform 1 starts the pump bodies on the adjacent traction unit 11 and the material guiding unit 131. The traction unit 11 works to gradually wind the metal wire around it through the die core 122, continuously processing the metal wire. The pump body on the material guiding unit 131 works to transport the lubricating oil stored in the storage tank 13 into the first fixed housing 12. The transported lubricating oil falls onto the metal wire, and a lubricating film is formed on the metal wire, reducing the direct contact and friction between the two. This not only protects the expensive wire drawing die core 122 and extends its service life, but also reduces the energy consumption during the wire drawing process. At the same time, the flowing lubricating oil takes away the heat on the die core 122 and the metal wire, completing the cooling operation of the two.

[0066] During the above metal wire processing process, if there are too many particulate impurities accumulated at the die core 122, the accumulated particulate impurities cause the friction force of the metal wire passing through the die core 122 to increase. If the strong pulling of the traction unit 11 causes the metal wire to break at the die core 122 at this time, the load detection component on the traction unit 11 detects that the traction force of the transported metal wire becomes weaker, and the control terminal will stop the traction unit 11 from working. At the same time, after the metal wire breaks, the tension force on it disappears. At this time, under the action of the torsion force of the torsion spring connected to the rotating frame 16, the rotating frame 16 swings, causing the guide wheel 17 on the rotating frame 16 to squeeze the metal wire to bend. When the guide wheel 17 on the rotating frame 16 squeezes the metal wire to fit the guide wheel 17 connected to the runner 19, the rotating frame 16 simultaneously drives the swing rod 18 to swing and fit the runner 19. Under the action of the barbs on the runner 19 and the rubber pad on the swing rod 18, the guide wheel 17 connected to the runner 19 cannot rotate. At this time, the two guide wheels 17 complete the clamping of the metal wire, avoiding the metal wire from breaking and injuring the nearby operators, and avoiding the metal wire from winding around other components and causing damage to the wire drawing equipment, that is, improving the safety and stability of the device. The rotation of the rotating frame 16 simultaneously drives the spur gear 21 to rotate. The spur gear 21 rotates along the rack 2, causing the rotating frame 16, the sliding frame 15 and the connected parts to move along the fixed rod 14. The movement of the rotating frame 16 releases the tension force on the metal wire, and the subsequent operator reinstalls and processes the metal wire.

[0067] Example 2: On the basis of Example 1, as Figure 4 and Figure 5 shown, it further includes: a first rotating shell 3, rotatably arranged on the first fixed shell 12, and a plurality of inclined blades 31 are fixedly connected to the inner wall of the first rotating shell 3; a motor 32, fixedly connected to the first fixed shell 12; a rotating shaft 33, rotatably arranged on the first fixed shell 12 and the fixed seat 121, the rotating shaft 33 is fixedly connected to the output shaft of the motor 32, and the rotating shaft 33 is driven by a gear set between it and the first rotating shell 3; a swinging member 34, rotatably arranged on the first rotating shell 3, and a torsion spring is installed between the swinging member 34 and the first rotating shell 3.

[0068] In the above solution: there are four inclined blades 31, and the four inclined blades 31 do not contact the metal wire. A counterweight is arranged on the left side of the swinging member 34, and a rubber sheet is arranged on the right side of the swinging member 34. An arc surface is arranged on the rubber sheet of the swinging member 34, and the arc surface of the rubber sheet is used to fit and wrap the metal wire. During the process of the first rotating shell 3 driving the swinging member 34 to rotate, the centrifugal force generated by the counterweight on the swinging member 34 is greater than the centrifugal force generated by the rubber sheet on it, so that the rubber sheets of the two swinging members 34 are close to each other.

[0069] Specific working principle: During the pre-installation of the metal wire, as the metal wire passes through the middle of the first rotating shell 3, the above-mentioned wire drawing operation is carried out subsequently. During the wire drawing operation, the control terminal starts the motor 32 at the same time. The motor 32 drives the rotating shaft 33 to rotate, and the rotating shaft 33 drives the first rotating shell 3 to rotate through the gear set. The first rotating shell 3 drives the four inclined blades 31 and the two swinging members 34 on it to rotate circumferentially together.

[0070] During the circumferential rotation of the four inclined blades 31, the four of them stir the air flow in the first rotating shell 3. The air flow pre-cools the metal wire passing through the first rotating shell 3, avoiding the weakening of the strength of the metal wire due to too high temperature, thus avoiding the breakage of the metal wire during the subsequent wire drawing process, and at the same time, the flowing air blows on the die core 122, reducing the working temperature of the die core 122 and slowing down its wear rate, prolonging the service life.

[0071] During the circumferential rotation of the two swinging members 34, the counterweight on the swinging member 34 is affected by the centrifugal force, and the swinging member 34 swings and twists the connected torsion spring, so that the rubber sheet of the swinging member 34 fits the surface of the metal wire. At this time, the rubber sheet of the swinging member 34 drives away and cleans the lubricating oil attached to the metal wire, avoiding the slippage of the metal wire during the subsequent conveying process, and further improving the stability of the wire drawing process.

[0072] Example 3: On the basis of Example 2, as Figure 4 , Figure 6 and Figure 7As shown, it also includes: a material guide shell 5, which is fixedly connected to the first fixed shell 12, and the material guide shell 5 is located below the discharge port on the material guide unit 131; a second rotating shell 51, which is rotatably arranged on the material guide shell 5, and the second rotating shell 51 and the rotating shaft 33 are driven by a gear set. The inner wall of the second rotating shell 51 is fixedly connected with a plurality of spiral blades 52, and the spiral blades 52 are located in the material guide shell 5.

[0073] In the above scheme: the flow area of ​​the middle channel of the guide shell 5 gradually increases from right to left, which is convenient for the lubricating oil to flow rightward in the guide shell 5. There are two spiral blades 52, and there is a certain gap between the inner side of the spiral blade 52 and the metal wire. When processing metal wires of different specifications, spiral blades 52 of different specifications can be selected to control the gap between the spiral blades 52 and the metal wire, so that a layer of lubricating oil of a specified thickness adheres to the surface of the metal wire.

[0074] Specific working principle: During the pre-installation of the metal wire, the metal wire repeats the above operation and passes through the guide shell 5, and then the device performs wire drawing, wherein the lubricating oil falls into the guide shell 5, and is guided by the guide shell 5, the lubricating oil accumulates in the guide shell 5 and flows to the left, and at this time, the lubricating oil accumulated in the guide shell 5 wraps the metal wire, so that the outer surface of the metal wire is fully attached with the lubricating oil. In this process, the rotating shaft 33 rotates and drives the second rotating shell 51 and the two spiral blades 52 to rotate through the gear set. The spiral blades 52 rotate and stir the lubricating oil in the guide shell 5 to move to the left, and the lubricating oil forms a lubricating oil film of uniform thickness on the outside of the metal wire, which not only significantly reduces the friction between the mold core 122 and the surface of the metal wire, but also ensures that the metal wire is subjected to consistent pressure when passing through the mold core 122, which helps the processed metal wire to obtain a smoother and flatter surface quality and reduce scratches and other surface defects.

[0075] Embodiment 4: Based on the embodiment 3, Figure 4 , Figure 6 and Figure 7 As shown, it also includes: a gas delivery unit 6, installed on the first fixed shell 12, the gas delivery unit 6 is composed of a conduit and a micro air pump; a first nozzle 61, installed on the conduit of the gas delivery unit 6; a fixed ring 62, fixedly connected to the conduit of the gas delivery unit 6; a second fixed shell 63, fixedly connected to the second rotating shell 51, and rotatably connected to the fixed ring 62, the second fixed shell 63 is fixedly connected with a plurality of second nozzles 64, the fixed ring 62 and the second fixed shell 63 form an annular chamber, and the annular chamber composed of the two is connected to the conduit on the delivery unit 6 and the second nozzle 64.

[0076] In the above solution: The first nozzle 61 is located above the die core 122. A sealing ring is provided between the second fixed shell 63 and the fixing ring 62 to improve the sealing performance between them. There are two second nozzles 64, which are inclined. The second nozzles 64 point to the joint of the die core 122 and the metal wire, facilitating the jetting of air by the first nozzle 61 and the second nozzles 64, and driving the lubricating oil and impurities on the right side of the die core 122 to move downward in all directions.

[0077] Specific working principle: During the wire drawing operation, the control terminal simultaneously starts the micro air pump on the gas delivery unit 6, so that the external gas is ejected from the first nozzle 61 through the gas delivery unit 6. At the same time, the gas is ejected from the two second nozzles 64 through the space between the fixing ring 62 and the second fixed shell 63. The gas ejected from the first nozzle 61 blows the lubricating oil to flow downward from the die core 122, accelerating the downward flow of the lubricating oil carrying particulate impurities, thereby reducing the amount of particulate impurities accumulated at the die core 122, ensuring that the friction force between the die core 122 and the metal wire remains within a stable range, and thus avoiding the breakage of the metal wire due to excessive temperature rise caused by the increase in friction force.

[0078] During the jetting of the second nozzles 64, the second rotating shell 51 rotates and drives the two second nozzles 64 to rotate circumferentially through the second fixed shell 63. The circumferential rotation of the two second nozzles 64 further drives the downward flow of the particulate impurities and the lubricating oil at the bottom of the die core 122, reducing the amount of particulate impurities accumulated near the die core 122, that is, improving the quality of the final metal wire product and extending the service life of the equipment.

[0079] Example 5: On the basis of Example 4, as Figures 8-10 shown, it further includes: a diversion shell 7, fixedly connected and communicated with one side of the first fixed shell 12 close to the material guiding shell 5, and the diversion shell 7 is fixedly connected and communicated with the storage tank 13; a filter frame 71, rotatably arranged in the diversion shell 7, and the filter frame 71 is opposite to the communication port between the diversion shell 7 and the storage tank 13; a discharge shell 72, fixedly connected and communicated with the diversion shell 7, and the communication port between the discharge shell 72 and the diversion shell 7 is located below the filter frame 71; a sliding plate 73, installed in the discharge shell 72, and a knob for pressing the sliding plate 73 is rotatably arranged on the discharge shell 72. The inner side surface of the filter frame 71 is frustum-shaped, and the upper cross-section of the frustum shape on the filter frame 71 is smaller than the lower cross-section, for guiding the impurities intercepted by the filter frame 71 to move downward. As Figure 9 and Figure 10 shown, it further includes: a sliding baffle 8, slidably arranged on the first fixed shell 12, the sliding baffle 8 is used to block the communication port between the diversion shell 7 and the first fixed shell 12, and a floating float is arranged on the sliding baffle 8; a limiting post 81, slidably arranged on the sliding baffle 8, and a tension spring is installed between the limiting post 81 and the sliding baffle 8; a limiting block 82, fixedly connected to the inner wall of the first fixed shell 12, and the limiting block 82 is used to change the movement state of the sliding baffle 8.

[0080] As shown Figure 10 in the figure, it further includes: a fixing frame 83 fixedly connected to the filter frame 71; a turbine 84 fixedly connected to the fixing frame 83.

[0081] In the above solution: the inner bottom surface of the first fixed shell 12 is inclined, the side of the first fixed shell 12 away from the diversion shell 7 is higher than the side close to the diversion shell 7, the communication port between the diversion shell 7 and the storage tank 13 is located in its upper part, the sliding baffle 8 is provided with a float, a ball is provided on the side of the limit post 81 close to the limit block 82, and an inclined surface is provided on the lower side of the limit block 82. The inclined surface of the limit block 82 is inclined downward and to the right from top to bottom (taking Figure 10 ... as an example). The inclined surface of the limit block 82 restricts the upward movement of the sliding baffle 8 and the limit post 81. When the liquid level of the lubricating oil is higher than the upper surface of the float on the sliding baffle 8, the buoyancy force on the sliding baffle 8 is greater than the limiting force of the inclined surface on the limit block 82 on the limit post 81. The limit post 81 moves to stretch the connected tension spring, and the ball of the limit post 81 is located on the left side surface of the limit block 82. At this time, the sliding baffle 8 quickly moves upward and releases the occlusion of the communication port between the first fixed shell 12 and the diversion shell 7, so that a large amount of lubricating oil flows in the diversion shell 7 and impacts the turbine 84 to rotate.

[0082] Specific working principle: During the wire drawing process, the lubricating oil carrying particulate impurities accumulates at the bottom of the first fixed shell 12. When the liquid level of the lubricating oil is higher than the upper surface of the float on the sliding baffle 8, the accumulated lubricating oil will lift the float of the sliding baffle 8, and the limit post 81 will move to stretch the connected tension spring. Subsequently, the sliding baffle 8 moves upward to release the occlusion of the communication port between the diversion shell 7 and the first fixed shell 12. At this time, the ball on the limit post 81 contacts the left side surface of the limit block 82. Due to the small friction force between the two, the sliding baffle 8 drives the limit post 81 to quickly move upward under the action of the buoyancy force. Subsequently, the lubricating oil in the first fixed shell 12 flows into the storage tank 13 through the diversion shell 7. Among them, the flowing lubricating oil impacts the turbine 84 to rotate, and the turbine 84 drives the filter frame 71 to rotate through the fixing frame 83. During this process, the filter screen on the filter frame 71 intercepts the particulate impurities in the lubricating oil. At the same time, during the rotation of the filter frame 71, under the guiding action of the round table surface on the filter frame 71, the particulate impurities move downward to the lower part of the filter frame 71, so that the particulate impurities accumulate at the lower part of the diversion shell 7. The above working process recycles the lubricating oil, significantly reducing costs and improving the resource utilization rate of the lubricating oil.

[0083] After all the lubricating oil in the first fixed shell 12 is completely drained into the storage tank 13, the sliding baffle 8 moves downward and resets under the action of gravity. Subsequently, the lubricating oil continues to accumulate in the storage tank 13, and then the above operation steps of the lubricating oil circulating flow are repeated.

[0084] After working for a period of time, the operator turns the knob on the discharge shell 72, then pulls out the sliding plate 73 to dump out the granular impurities accumulated in the lower part of the guide shell 7, and then reinstalls the sliding plate 73 into the discharge shell 72 and tightens the knob on the discharge shell 72.

[0085] Embodiment 6: Based on Embodiment 5, Figures 1-10 As shown, the present invention also provides a wire drawing process for producing prestressed materials for rail sleepers, based on the above-mentioned wire drawing equipment for producing prestressed materials for rail sleepers, comprising the following steps:

[0086] S1: firstly rotate the rotating frame 16, place the metal wire between the guide wheel 17 connected to the rotating frame 16 and the guide wheel 17 connected to the sliding frame 15, then pull the metal wire through the first fixed shell 12, the guide shell 5, the mold core 122 and the first rotating shell 3, and then wind the metal wire onto the traction unit 11 to complete the pre-installation of the metal wire;

[0087] S2: After the metal wire is pre-installed, the traction unit 11, the material guide unit 131, the motor 32 and the gas delivery unit 6 are started, wherein the traction unit 11 works to pull the metal wire through the mold core 122, and the material guide unit 131 works to transport the lubricating oil stored in the storage tank 13 to the material guide shell 5 and attach it to the metal wire;

[0088] S3: During the movement of the metal wire, the motor 32 works to rotate the first rotating shell 3 and the second rotating shell 51 together through the connected parts, wherein the first rotating shell 3 drives the inclined blades 31 to rotate to guide the gas flow, and the second rotating shell 51 rotates to drive the spiral blades 52 to rotate to drive the lubricating oil in the guide shell 5 to flow;

[0089] S4: During the movement of the metal wire, the gas delivery unit 6 works to make the gas in the first nozzle 61 and the second nozzle 64 blow the lubricating oil at the mold core 122 to flow, and the excess lubricating oil flows into the first fixed shell 12. When a certain amount of lubricating oil accumulates in the first fixed shell 12, the lubricating oil will lift the sliding baffle 8 to move upward, and then the lubricating oil will enter the storage tank 13 through the guide shell 7. During this process, the filter screen on the filter frame 71 intercepts impurities such as particulate impurities in the lubricating oil, and at the same time, the lubricating oil impacts the turbine 84, and the fixed frame 83 and the filter frame 71 rotate together;

[0090] S5: After the lubricating oil is drained, the sliding baffle 8 is reset by gravity, and then the lubricating oil is accumulated in the first fixed shell 12, and then the above-mentioned diversion operation is repeated to circulate the lubricating oil;

[0091] S6: During the process of processing metal wire, when the metal wire breaks, under the torsional force of the torsion spring connected to the rotating frame 16, the rotating frame 16 drives the guide wheel 17 thereon to rotate and bend the metal wire, so that the guide wheel 17 on the rotating frame 16 fits and presses the bent metal wire with the guide wheel 17 below the same-side runner 19. While the rotating frame 16 rotates, the swing rod 18 swings to fit the runner 19. At this time, the guide wheel 17 connected to the runner 19 cannot rotate, and the clamping of the metal wire is completed.

The scope of the following claims should be given the broadest interpretation so as to cover all modifications and equivalent structures and functions.
