Description

Technical Field

[0001] This invention relates to the field of metal wire drawing equipment technology, specifically a high-ductility metal wire drawing equipment and its drawing process. Background Technology

[0002] A metal wire drawing machine is a specialized piece of equipment used to draw metal wires through a die, reducing their diameter, increasing their length, and improving their mechanical properties and surface quality. Drawing is an important plastic deformation process in metal processing and is widely used in industries such as wire and cable, metal products, construction, automobiles, and aerospace.

[0003] A drawing machine applies tension to a metal wire through a traction device (such as a drum or chain), causing it to pass through a die fixed on the frame. Under the action of tension, the metal wire undergoes plastic deformation, resulting in a decrease in cross-sectional size and an increase in length.

[0004] Currently, existing metal wire drawing equipment is inconvenient for high-stability stretching and for stretching reset during use. Therefore, improvements are needed to address these issues. Summary of the Invention

[0005] To address the problems in the prior art, this invention provides a high-ductility metal wire drawing device and its drawing process.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a high-ductility metal wire drawing equipment and its drawing process, including a stretching control structure, a cooperating traction structure and a pushing feeding structure, wherein the side end of the stretching control structure is connected to the cooperating traction structure, and the side end of the cooperating traction structure is connected to the pushing feeding structure.

[0007] The stretching adjustment structure is used for stretching treatment of metal wires. The second stepper motor controls the rotation of the control disk, and the first stepper motor controls the rotation of the docking bracket. The docking bracket contacts the chain and pushes the connecting ring and sliding guide block to move laterally. The symmetrically arranged first electro-hydraulic rod controls the closing adjustment of the two extrusion ends and rubber ends.

[0008] In conjunction with the traction structure, the second electro-hydraulic rod, which is used to guide and limit the metal wire, changes the position of the rotation control rod by extending and retracting, so that the extrusion wheel can extrude and limit the metal wire.

[0009] The push-feed structure is used to push the metal wire. The hydraulic push rod pushes the metal wire to slide on the placement slot and guide seat.

[0010] Specifically, the stretching adjustment structure includes a stretching component and a limiting component. The stretching component controls the lateral adjustment of the limiting component, and the stretching component can also control the resetting of the limiting component.

[0011] Specifically, the stretching component includes a support sleeve, a hydraulic telescopic connecting rod, and a limiting round rod. The hydraulic telescopic connecting rod is hinged on the support sleeve. The side end of the hydraulic telescopic connecting rod is hinged to the connecting ring. The connecting ring slides and adjusts on the limiting round rod. The lower end of the limiting round rod is fixedly connected to a support base plate. The connecting ring is also fixedly connected to a sliding guide block.

[0012] Specifically, the stretching component also includes an electric motor, which controls the rotation of the sprockets. Multiple sprockets are driven synchronously by a synchronous toothed belt. Chains are meshed on the sprockets, and the electric motor is fixed on a symmetrically arranged support base plate.

[0013] Specifically, the limiting component includes a docking seat block, a first electro-hydraulic rod, and a support base block. A hinge shaft is fixedly connected to the support base block, and a swing adjustment frame is hinged to the hinge shaft. The swing adjustment frame is provided with a pressing end, and a rubber end is fixedly provided on the pressing end. The first electro-hydraulic rod is hinged to the middle of the swing adjustment frame, and the end of the first electro-hydraulic rod away from the pressing end is hinged to the docking seat block.

[0014] Specifically, a docking mechanism is fixedly installed on the sliding guide block, which is used for the limiting connection between the sliding guide block and the chain.

[0015] Specifically, the docking mechanism includes a first stepper motor and a docking bracket. The first stepper motor controls the rotation and adjustment of the docking bracket. The first stepper motor is mounted on a rotation control disk, and a second stepper motor is mounted at the rear end of the rotation control disk. The second stepper motor controls the rotation and adjustment of the rotation control disk.

[0016] Specifically, the traction structure includes a support frame, an extrusion groove seat, and a guide groove seat. The support frame is fixedly provided with an extrusion groove seat at its upper limit. The side end of the extrusion groove seat is connected to the guide groove seat. An extrusion wheel is provided at the end of the guide groove seat away from the support frame. The extrusion wheel is movable and adjustable on the guide groove seat. The lower end of the extrusion wheel is fixedly connected to a rotation control rod. A second electro-hydraulic rod is hinged to the middle of the rotation control rod. One end of the second electro-hydraulic rod is hinged to a mating hinge block. The mating hinge block is fixed to the bottom of the support frame.

[0017] Specifically, the pushing feeding structure includes a guide seat and a placement slot seat. The side end of the guide seat is connected to the placement slot seat, and the side end of the placement slot seat is connected to the adapter block. A hydraulic push rod is installed on the adapter block. The guide seat, placement slot seat, and adapter block are supported and fixed by a fixed base block. The side end of the guide seat is connected to the guide slot seat. The swing adjustment frame contacts the metal wire through the extrusion end and the rubber end. The lower end of the docking block is fixed to the sliding guide block. The lower end of the support base block is fixed to the sliding guide block. The second stepper motor is fixed on the sliding guide block, and the docking mechanism does not contact the support base block or the swing adjustment frame.

[0018] A drawing process for a high-ductility metal wire drawing equipment includes the following steps:

[0019] S1. First, the metal wire is placed on the placement slot. The hydraulic push rod extends to push the metal wire, allowing it to pass through the placement slot to the guide seat. The metal wire can be transmitted on the guide slot and then discharged through the extrusion slot. At this time, the second electro-hydraulic rod is stretched, which drives the rotation control rod to rotate, causing the extrusion wheel to move towards the axial position of the guide slot, thus extruding and limiting the metal wire.

[0020] S2. After that, when the metal wire is discharged through the extrusion groove seat, the first electro-hydraulic rod extends. The first electro-hydraulic rod can change its angle through the docking seat block. When the first electro-hydraulic rod extends, it can make the swing adjustment frame rotate around the hinge axis, change the position of the extrusion end and the rubber end, and extrusion ends and rubber ends on both sides are squeezed towards the center position, thereby limiting the metal wire.

[0021] S3. Then, the second stepper motor controls the rotation of the control disk to make the docking bracket reach the specified height position. At the same time, the first stepper motor controls the rotation of the docking bracket to connect the docking bracket with the chain limit, thereby limiting the chain and the docking bracket and facilitating the drive and stretching work.

[0022] S4. Finally, the motor drives the sprockets to rotate. Multiple sprockets are connected by a synchronous toothed belt. Simultaneously, the sprockets drive the chain to rotate. At this time, the chain drives the sliding guide block and connecting ring sleeve to move as a whole through the docking mechanism. The connecting ring sleeve can slide at the upper limit of the limiting round rod. The movement of the sliding guide block drives the support base block to move in coordination, so that the extrusion end and rubber end can stretch the metal wire to achieve the processing of the metal wire. During stretching, the hydraulic telescopic connecting rod is compressed by force. At the same time, the lower end of the hydraulic telescopic connecting rod is hinged to the connecting ring sleeve, and the upper end of the hydraulic telescopic connecting rod is hinged to the support sleeve seat, which can be adjusted in angle. Then, through program control, the docking bracket is disengaged from the chain, and the limiting component cancels the limit on the metal wire. At this time, the connecting ring sleeve, sliding guide block, and limiting component are reset under the action of the hydraulic telescopic connecting rod, which facilitates the stretching process again.

[0023] The beneficial effects of this invention are:

[0024] I. This invention, through the structural design of the tension adjustment structure, facilitates the tensioning of metal wires and the resetting of the structure. The motor controls the sprocket to rotate, and the sprocket is synchronously driven by the synchronous toothed belt, thereby driving the upper chain to rotate. When the chain rotates, the second stepper motor controls the rotation control disk to rotate, and the first stepper motor controls the docking bracket to rotate, so that the docking bracket contacts the chain. Thus, the chain can pull the connecting ring sleeve, sliding guide block, and limiting component to move as a whole. The first electro-hydraulic rod on the docking seat block changes the position of the swing adjustment frame through telescopic control, so that the swing adjustment frame rotates around the hinge axis, changing the position of the extrusion end and the rubber end. The extrusion ends and rubber ends on both sides contact the metal wire to extrude and limit the metal wire, thereby driving the metal wire to be stretched and adjusted.

[0025] Second, the present invention, through the structural design of the traction structure, facilitates the limiting and guiding of metal wire. The metal wire is transmitted on the guide slot seat. At this time, the second electro-hydraulic rod can be stretched and controlled, so that the rotation control rod rotates around the left side position, changing the position of the extrusion wheel, so that the extrusion wheel makes limiting contact with the metal wire, improving the limiting of the metal wire at the rear, and better helping the stretching control of the metal wire. The metal wire can be guided into the equipment through the placement slot seat. The hydraulic push rod extends, driving the metal wire to slide and adjust on the placement slot seat and guide seat.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] The invention will be further described below with reference to the accompanying drawings. Example

[0038] like Figure 1-8 As shown, the present invention provides a high-ductility metal wire drawing device and its drawing process, including a stretching control structure 1, a cooperating traction structure 2 and a pushing feed structure 3. The side end of the stretching control structure 1 is connected to the cooperating traction structure 2, and the side end of the cooperating traction structure 2 is connected to the pushing feed structure 3.

[0039] The stretching adjustment structure 1 is used for stretching metal wire. The second stepper motor 33 controls the rotation control disk 32 to rotate, and the first stepper motor 30 controls the docking bracket 31 to rotate. The docking bracket 31 contacts the chain 12, pushing the connecting ring sleeve 10 and the sliding guide block 11 to move laterally. The symmetrically arranged first electro-hydraulic rod 20 controls the closing adjustment of the two sides extrusion end 24 and rubber end 25.

[0040] In conjunction with the traction structure 2, which is used to guide and limit the metal wire, the second electro-hydraulic rod 39 changes the position of the rotation control rod 37 by extending and retracting, so that the extrusion wheel 40 extrudes and limits the metal wire.

[0041] The push-feed structure 3 is used to push the metal wire. The hydraulic push rod 45 pushes the metal wire to slide on the placement slot 42 and the guide seat 41.

[0042] The tension control structure 1 includes a tension component 4 and a limiting component 5. The tension component 4 controls the lateral adjustment of the limiting component 5, and the tension component 4 can also control the limiting component 5 to reset.

[0043] The tensioning component 4 includes a support sleeve 6, a hydraulic telescopic connecting rod 7, and a limiting round rod 8. The hydraulic telescopic connecting rod 7 is hinged to the support sleeve 6. The side end of the hydraulic telescopic connecting rod 7 is hinged to the connecting ring sleeve 10. The connecting ring sleeve 10 slides on the limiting round rod 8. The lower end of the limiting round rod 8 is fixedly connected to a support base plate 9. The connecting ring sleeve 10 is also fixedly connected to a sliding guide block 11. The motor 15 drives one of the sprockets 13 to rotate. The front ends of multiple sprockets 13 are fixed with toothed pulleys. Multiple toothed pulleys are meshed and connected by a synchronous toothed belt 14, which can synchronously drive all sprockets 13 to rotate. At the same time, the sprockets 13 mesh with the chain 12, driving the chain 12 to rotate. At this time, the chain 12 drives the sliding guide block 11 and the connecting ring sleeve 10 to move as a whole through the docking mechanism 29. The sleeve 10 can slide at the upper limit of the limiting round rod 8. The movement of the sliding guide block 11 drives the support base block 21 to move in coordination, so that the extrusion end 24 and the rubber end 25 drive the metal wire to stretch, thereby realizing the processing of the metal wire. During stretching, the hydraulic telescopic connecting rod 7 is subjected to pressure and extrusion. At the same time, the lower end of the hydraulic telescopic connecting rod 7 is hinged to the connecting ring sleeve 10, and the upper end of the hydraulic telescopic connecting rod 7 is hinged to the support sleeve 6, which can be adjusted in angle. When the connecting ring sleeve 10 and the sliding guide block 11 reach the bottom position, the docking bracket 31 can be disengaged from the chain 12 through program control. At the same time, the limiting component 5 cancels the limit on the metal wire. At this time, the connecting ring sleeve 10, the sliding guide block 11, and the limiting component 5 are reset under the action of the hydraulic telescopic connecting rod 7, which facilitates the stretching process again.

[0044] The stretching component 4 also includes a motor 15, which controls the rotation of sprockets 13. Multiple sprockets 13 are synchronously driven by a synchronous toothed belt 14. Chains 12 are meshed onto the sprockets 13. The motor 15 is fixed to symmetrically arranged support base plates 9. The structural design of the stretching adjustment structure 1 facilitates the stretching of metal wires and the repositioning of the structure. The motor 15 controls the rotation of the sprockets 13, which are synchronously driven by the synchronous toothed belt 14, thereby driving the upper chain 12 to rotate. When the chain 12 rotates, the second stepper motor 33 controls the rotation of the control disk 32. The first stepper motor 30 controls the docking bracket 31 to rotate, so that the docking bracket 31 contacts the chain 12. Thus, the chain 12 can pull the connecting ring sleeve 10, the sliding guide block 11, and the limiting component 5 to move as a whole. The first electro-hydraulic rod 20 on the docking seat block 19 changes the position of the swing adjustment frame 22 through extension and retraction control, so that the swing adjustment frame 22 rotates around the hinge axis 23, changing the position of the extrusion end 24 and the rubber end 25. The extrusion ends 24 and the rubber end 25 on both sides contact the metal wire to extrude and limit the metal wire, thereby driving the metal wire to stretch and adjust.

[0045] The limiting component 5 includes a docking seat block 19, a first electro-hydraulic rod 20, and a support base block 21. A hinge shaft 23 is fixedly connected to the support base block 21. A swing adjustment frame 22 is hinged to the hinge shaft 23. A pressing end 24 is provided on the swing adjustment frame 22. A rubber end 25 is fixedly provided on the pressing end 24. The first electro-hydraulic rod 20 is hinged to the middle of the swing adjustment frame 22. The end of the first electro-hydraulic rod 20 away from the pressing end 24 is hinged to the docking seat block 19. When the metal wire is discharged through the pressing groove seat 35, the first electro-hydraulic rod 20 extends. The first electro-hydraulic rod 20 can change its angle through the docking seat block 19. When the first electro-hydraulic rod 20 extends, it can make the swing adjustment frame 22 rotate around the hinge shaft 23, changing the position of the pressing end 24 and the rubber end 25. The pressing ends 24 and the rubber end 25 on both sides are pressed towards the center position, thereby limiting the metal wire.

[0046] A docking mechanism 29 is fixedly installed on the sliding guide block 11. The docking mechanism 29 is used for the limiting connection between the sliding guide block 11 and the chain 12.

[0047] The docking mechanism 29 includes a first stepper motor 30 and a docking bracket 31. The first stepper motor 30 controls the rotation and adjustment of the docking bracket 31. The first stepper motor 30 is mounted on a rotation control disk 32, and a second stepper motor 33 is mounted at the rear end of the rotation control disk 32. The second stepper motor 33 controls the rotation and adjustment of the rotation control disk 32.

[0048] The traction structure 2 includes a support frame 34, an extrusion groove seat 35, and a guide groove seat 36. The extrusion groove seat 35 is fixedly mounted on the upper limit of the support frame 34. The side end of the extrusion groove seat 35 is connected to the guide groove seat 36. An extrusion wheel 40 is provided at the end of the guide groove seat 36 away from the support frame 34. The extrusion wheel 40 is movable and adjustable on the guide groove seat 36. The lower end of the extrusion wheel 40 is fixedly connected to a rotation control rod 37. A second electro-hydraulic rod 39 is hinged to the middle of the rotation control rod 37. One end of the second electro-hydraulic rod 39 is hinged to a mating hinge block 38. The mating hinge block 38 is fixed to the bottom of the support frame 34. By cooperating with the structural setting of the traction structure 2, it is convenient to limit and guide the metal wire. The metal wire is transmitted on the guide slot 36. At this time, the second electro-hydraulic rod 39 can be stretched and controlled, so that the rotation control rod 37 rotates around the left side position, changing the position of the extrusion wheel 40, so that the extrusion wheel 40 makes limit contact with the metal wire, improving the limit of the metal wire at the rear, and better helping the metal wire stretching control. The metal wire can be guided into the equipment through the placement slot 42. The hydraulic push rod 45 extends, driving the metal wire to slide and adjust on the placement slot 42 and the guide seat 41.

[0049] The feeding structure 3 includes a guide seat 41 and a placement slot 42. The side end of the guide seat 41 is connected to the placement slot 42, and the side end of the placement slot 42 is connected to the adapter block 44. A hydraulic push rod 45 is installed on the adapter block 44. The guide seat 41, placement slot 42, and adapter block 44 are supported and fixed by a fixed base block 43. The side end of the guide seat 41 is connected to the guide slot 36. The swing adjustment frame 22 contacts the metal wire through the extrusion end 24 and the rubber end 25. The lower end of the docking block 19 is fixed to the sliding guide block 11, and the lower end of the support base block 21 is fixed to the sliding guide block 11. The second stepper motor 33 is fixed on the sliding guide block 11, and the docking mechanism 29 does not contact the support base block 21 or the swing adjustment frame 22. The metal wire is placed on the placement slot 42, which is supported and limited by the fixed base block 43 and the adapter block 44. A hydraulic push rod 45 is installed on the adapter block 44. The hydraulic push rod 45 can push the metal wire to move by extending, so that the metal wire passes through the placement slot 42 to the guide seat 41. The side end of the guide seat 41 is connected to the guide slot 36, and the metal wire can be transmitted on the guide slot 36. Then it is discharged through the extrusion slot 35. The second electro-hydraulic rod 39 is stretched, which drives the rotation control rod 37 to rotate, so that the extrusion wheel 40 moves to the axial position of the guide slot 36 to extrude and limit the metal wire, so that the metal wire is subjected to extrusion force, which better facilitates the subsequent stretching work.

[0050] The working principle is as follows: When in use, the user places the metal wire on the placement slot 42. The placement slot 42 is supported and limited by the fixed base block 43 and the adapter block 44. A hydraulic push rod 45 is installed on the adapter block 44. The hydraulic push rod 45 can push the metal wire to move by extending, so that the metal wire passes through the placement slot 42 to the guide seat 41. The side end of the guide seat 41 is connected to the guide slot 36. The metal wire can be transmitted on the guide slot 36 and then discharged by squeezing the slot 35.

[0051] At this time, the second electro-hydraulic rod 39 is stretched, which drives the rotation control rod 37 to rotate, causing the extrusion wheel 40 to move axially towards the guide slot seat 36 to extrude and limit the metal wire, so that the metal wire is subjected to extrusion force, which better facilitates the subsequent stretching work.

[0052] When the metal wire is discharged through the extrusion groove seat 35, the first electro-hydraulic rod 20 extends. The first electro-hydraulic rod 20 can change its angle through the docking seat block 19. When the first electro-hydraulic rod 20 extends, it can make the swing adjustment frame 22 rotate around the hinge axis 23, changing the position of the extrusion end 24 and the rubber end 25. The extrusion ends 24 and the rubber end 25 on both sides are squeezed towards the center position, thereby limiting the metal wire.

[0053] Then, the second stepper motor 33 controls the rotation control disk 32 to rotate, so that the docking bracket 31 reaches the specified height position. At the same time, the first stepper motor 30 controls the docking bracket 31 to rotate, and limits the docking bracket 31 to the chain 12, thereby restricting the chain 12 and the docking bracket 31, which facilitates the drive and stretching work.

[0054] Then, the motor 15 drives the sprocket 13 to rotate. Multiple sprockets 13 are connected by a synchronous toothed belt 14 to achieve synchronous driving. Simultaneously, the sprocket 13 meshes with the chain 12, causing the chain 12 to rotate. At this time, the chain 12, through the docking mechanism 29, drives the sliding guide block 11 and the connecting ring 10 to move as a whole. The connecting ring 10 can slide at the upper limit of the limiting rod 8. The movement of the sliding guide block 11 drives the support base block 21 to move in coordination, causing the extrusion end 24 and the rubber end 25 to stretch the metal wire, thus processing and stretching the metal wire. At this time, the hydraulic telescopic link 7 is compressed by force, and the lower end of the hydraulic telescopic link 7 is hinged to the connecting ring sleeve 10, and the upper end of the hydraulic telescopic link 7 is hinged to the support sleeve 6, which can be adjusted in angle. When the connecting ring sleeve 10 and the sliding guide block 11 reach the bottom position, the docking bracket 31 can be disengaged from the chain 12 through program control. At the same time, the limiting component 5 cancels the limit on the metal wire. At this time, the connecting ring sleeve 10, the sliding guide block 11, and the limiting component 5 are reset under the action of the hydraulic telescopic link 7, which facilitates the stretching process again and completes the work.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
