Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment, and in particular to a wire drawing device and method for conveniently changing the wire drawing die. Background Technology

[0002] With the development of industrial technology, modern wire drawing equipment technology has become more and more sophisticated. Metal wires need to be processed into materials with finer diameters, which requires the raw metal wires to pass through the wire drawing die. For customized wire drawing materials, there are many models of these materials, which requires frequent changes of the wire drawing die. Each time the staff changes the die, a lot of time is spent, which reduces work efficiency.

[0003] Secondly, the metal wire needs to pass through a coolant during the drawing process, and water also adheres to the surface of the wire during the winding process. This water will corrode the material and affect the quality of the metal wire. Summary of the Invention

[0004] The purpose of this invention is to provide a wire drawing device and method for conveniently replacing wire drawing dies. When the wire drawing die between the locking plate and the docking plate needs to be replaced, the operator flips all the docking plates over using the connecting plate, opening the arc-shaped opening between the locking plate and the docking plate. During the wire drawing process, the replacement die to be loaded is pre-installed on the locking post. Then, the operator holds the wrench to manipulate the torque column to twist and pull. The locking post without the replacement die is first inserted into the wire drawing hole of the wire drawing die to remove the old part. Then, the replacement die is loaded and placed into the arc-shaped opening between the locking plate and the docking plate to load the new part. This reduces the time for replacing die parts and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire drawing device for convenient die replacement, comprising a wire drawing table, a processing groove in the middle of the wire drawing table filled with coolant, three linearly arrayed locking plates in the middle of the wire drawing table, a mating plate rotatably mounted on the top of the locking plates, arc-shaped openings on the surfaces where the locking plates and mating plates engage, a wire drawing die installed between two of the arc-shaped openings, an extension plate at the front end of the wire drawing table, a discharge roller rotatably mounted in the middle of the extension plate, a metal wire being drawn out from the outer side of the discharge roller, and the metal wire passing through the three locking plates of the wire drawing table. The wire drawing die has wire threading ports at both the front and rear ends of the wire drawing table, which are matched with the wire. The wire is connected to the winding roller at the rear of the wire drawing table. The left and right side walls of the wire drawing table have clearance notches that match the docking plate. A load-bearing plate is provided on the left side of the wire drawing table, and a torsion shaft seat is provided on the load-bearing plate. A torsion crossbar is inserted inside the torsion shaft seat. Three sets of material changing beams are provided on the torsion crossbar. Each set of material changing beams consists of two bent rods. The ends of the two bent rods are provided with locking posts. A replacement die is installed on the locking post at the rear end. An erasing component is provided at the rear of the wire drawing table.

[0006] Furthermore, the docking plate has a structure of a sheet metal shell with a wall thickness of one millimeter, and the interior of the metal shell is filled with counterweight lead blocks.

[0007] Furthermore, the top of the docking plate is fixedly connected by a series plate, which is made of wood and is fixedly connected to each docking plate by bolts.

[0008] Furthermore, a limiting disc is engaged on both the front and rear ends of the wire drawing die, and the limiting disc is attached to the side wall of the engaging plate and the mating plate.

[0009] Furthermore, the locking post has a threaded head at its end, the material changing cantilever beam has a threaded hole at its end, and the locking post has a ring-shaped array of metal springs on its outer side, the metal springs being made of bent steel sheets.

[0010] Furthermore, a wrench is provided at the end of the torsion cross column, and a threaded hole is provided in the middle of the torsion shaft seat. A screw valve is inserted into the threaded hole, and a rubber ball is provided at the end of the screw valve to abut against the outer wall of the torsion cross column.

[0011] Furthermore, the erasing assembly includes an extension platform, which is fixed to the side wall of the wire drawing table via a mounting flange. A replacement shaft seat is fixedly installed at the top of the extension platform, and a bifurcated bridge is rotatably provided on one side of the replacement shaft seat. The bifurcated bridge is connected to the output end of the stepper motor. Two arc-shaped frames are provided at the ends of the bifurcated bridges, and arc-shaped replacement grooves are provided on the arc-shaped frames. Arc-shaped sponge blocks are installed in the arc-shaped replacement grooves, and the gap between the arc-shaped sponge blocks is smaller than the finished diameter of the metal wire.

[0012] Furthermore, the following steps are included:

[0013] When the wire drawing die between the S1. clamping plate and the docking plate needs to be replaced, the operator flips all the docking plates over using the connecting plate, and the arc opening between the clamping plate and the docking plate is opened. During the wire drawing operation, the replacement die to be filled is pre-installed on the locking column. Then, the operator holds the wrench to operate the torque column to twist and pull. The locking column without the replacement die is first inserted into the wire drawing hole of the wire drawing die to remove the old part. Then, the replacement die is put into the arc opening between the clamping plate and the docking plate to install the new part, reducing the time for replacing die parts.

[0014] S2. After the metal wire drawing operation is completed, it passes through the middle of the two curved sponge blocks. The curved sponge blocks will wipe away the liquid on the outside of the metal wire. Every unit of time, the stepper motor will drive the bifurcated bridge to rotate at a certain angle, so that the curved sponge blocks can continuously have new areas to contact the metal wire. When the curved sponge block needs to be replaced, the other bifurcated bridge is rotated to reach the wiping station. The wiping curved sponge block is replaced with a new one during this interval, waiting for the next bifurcated bridge replacement.

[0015] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this invention are:

[0016] Firstly, when the device is in use, if the wire drawing die between the locking plate and the docking plate needs to be replaced, the operator flips all the docking plates over using the connecting plate, opening the arc-shaped opening between the locking plate and the docking plate. During the wire drawing process, the replacement die to be filled is pre-installed on the locking column. Then, the operator holds the wrench to manipulate the torque column to twist and pull. The locking column without the replacement die is first inserted into the wire drawing hole of the wire drawing die to remove the old part. Then, the replacement die is placed into the arc-shaped opening between the locking plate and the docking plate to install the new part, reducing the time for replacing die parts.

[0017] Secondly, after the metal wire drawing operation is completed, it passes through the middle of the two curved sponge blocks. The curved sponge blocks will wipe away the liquid on the outside of the metal wire. Every unit of time, the stepper motor will drive the bifurcated bridge to rotate at a certain angle, so that the curved sponge blocks can continuously have new areas to contact the metal wire. When the curved sponge blocks need to be replaced, the other bifurcated bridge is rotated to reach the wiping station. The wiping curved sponge blocks are replaced with new ones during this interval, waiting for the next bifurcated bridge replacement. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides, for example Figures 1-6The drawing device shown is a wire drawing device for easy die replacement, including a drawing table 1. A processing groove is provided in the middle of the drawing table 1, and coolant is filled into the processing groove. Three linearly arrayed locking plates 2 are provided in the middle of the drawing table 1. A docking plate 201 is rotatably mounted on the top of each locking plate 2. Both the locking plates 2 and the docking plate 201 have arc-shaped openings on their interlocking surfaces. A wire drawing die 9 is installed between two of the arc-shaped openings. An extension plate 102 is provided at the front end of the drawing table 1. A discharge roller 103 is rotatably mounted in the middle of the extension plate 102. A metal wire is drawn out from the outer side of the discharge roller 103 and passes through the three wire drawing dies 9 of the drawing table 1. The front and rear ends of the drawing table 1 are provided with wire-passing openings 101 that match the metal wire. The metal wire is connected to a winding roller at the rear of the drawing table 1. Alternating notches 10 that match the docking plates 201 are provided on the left and right side walls of the drawing table 1. 4. A load-bearing plate 8 is provided on the left side of the wire drawing table 1. A torque shaft seat 801 is provided on the load-bearing plate 8. A torque cross column 4 is inserted through the inner side of the torque shaft seat 801. Three sets of material changing beams 10 are provided on the torque cross column 4. Each set of material changing beams 10 consists of two bent rods. A locking post 12 is provided at the end of each of the two bent rods. A replacement mold 11 is installed on the locking post 12 at the rear end. An erasing component is provided at the rear of the wire drawing table 1. During the wire drawing operation, the replacement mold 11 to be filled is pre-installed on the locking post 12. Then, the operator holds the wrench 401 to operate the torque cross column 4 to twist and pull. The locking post 12 without the replacement mold 11 is first inserted into the wire drawing hole of the wire drawing mold 9 to remove the old part. Then, the replacement mold 11 with the replacement mold is sent to the arc-shaped opening between the clamping plate 2 and the docking plate 201 to install the new part, which reduces the time for changing mold parts.

[0028] The structure of the docking plate 201 is a sheet metal shell with a wall thickness of one millimeter. The interior of the metal shell is filled with counterweight lead blocks. The number of lead blocks inserted into the sheet metal shell is selected according to the actual situation of the wire drawing operation. If the diameter of the wire being drawn is relatively large, more lead blocks are inserted to increase the weight of the docking plate 201.

[0029] The top of the docking plate 201 is fixedly connected by the connecting plate 3. The connecting plate 3 is made of wood. The connecting plate 3 is fixedly connected to each docking plate 201 by bolts. The workers can flip all the docking plates 201 over by using the connecting plate 3. The use of wood for the connecting plate 3 can reduce the total weight.

[0030] A limiting disc is engaged on both the front and rear ends of the wire drawing die 9. The limiting disc is attached to the side wall of the engaging plate 2 and the docking plate 201. The limiting disc is firmly locked to the engaging plate 2 and the docking plate 201, so that the wire drawing die 9 will not shift in the axial direction.

[0031] The locking post 12 has a threaded head at its end, and the material changing beam 10 has a threaded hole at its end. The outer side of the locking post 12 is provided with a ring array of metal springs 1201. The metal springs 1201 are made of bent steel sheets. The metal springs 1201 expand outwards by their own elasticity. The locking post 12 is inserted into the wire drawing die 9 and the replacement die 11. The wire drawing die 9 and the replacement die 11 will be firmly bound to the locking post 12.

[0032] The end of the torque column 4 is provided with a wrench 401, and the torque shaft seat 801 is provided with a threaded hole in the middle. A screw valve 802 is inserted into the threaded hole. The end of the screw valve 802 is provided with a rubber ball that abuts against the outer wall of the torque column 4. When the torque column 4 is flipped outward, the screw valve 802 rotates into the torque shaft seat 801 and locks the outer wall of the torque column 4. The worker pre-fills the replacement mold 11 to be used next time at this station.

[0033] The erasing assembly includes an extension platform 5, which is fixed to the side wall of the wire drawing table 1 via a mounting flange 501. A replacement shaft seat 6 is fixedly mounted on the top of the extension platform 5. A bifurcated bridge 601 is rotatably mounted on one side of the replacement shaft seat 6, and the bifurcated bridge 601 is connected to the output end of a stepper motor 7. Two arc-shaped frames 602 are provided at each end of the bifurcated bridge 601. Arc-shaped replacement grooves are provided on the arc-shaped frames 602, and arc-shaped sponge blocks 603 are installed in the arc-shaped replacement grooves. The gap between the arc-shaped sponge blocks 603 is smaller than the finished diameter of the metal wire. After the wire drawing operation is completed, the wire passes between the two curved sponge blocks 603. The curved sponge blocks 603 will wipe away the liquid on the outside of the metal wire. Every unit of time, the stepper motor 7 will drive the branch bridge 601 to rotate at a certain angle, so that the curved sponge blocks 603 can continuously have new areas to contact the metal wire. When the curved sponge blocks 603 need to be replaced, the other branch bridge 601 is rotated to reach the wiping station. The wiping curved sponge blocks 603 are replaced with new ones during this interval, waiting for the next replacement of the branch bridge 601.

[0034] Includes the following steps:

[0035] When the wire drawing die 9 between the clamping plate 2 and the docking plate 201 needs to be replaced, the operator flips all the docking plates 201 over using the connecting plate 3, and the arc-shaped opening between the clamping plate 2 and the docking plate 201 is opened. During the wire drawing operation, the equipment pre-installs the replacement die 11 to be filled on the locking column 12. Then, the operator holds the wrench 401 to operate the torque column 4 to twist and pull. The locking column 12 without the replacement die 11 is first inserted into the wire drawing hole of the wire drawing die 9 to remove the old part. Then, the replacement die 11 is put into the arc-shaped opening between the clamping plate 2 and the docking plate 201 to install the new part, which reduces the time for replacing die parts.

[0036] S2. After the metal wire drawing operation is completed, it passes through the middle of the two arc-shaped sponge blocks 603. The arc-shaped sponge blocks 603 will wipe away the liquid on the outside of the metal wire. Every unit of time, the stepper motor 7 will drive the branch bridge 601 to rotate at a certain angle, so that the arc-shaped sponge block 603 can continuously have new areas to contact the metal wire. When the arc-shaped sponge block 603 needs to be replaced, the other branch bridge 601 is rotated to reach the wiping station. The wiping arc-shaped sponge block 603 is replaced with a new one during this interval, waiting for the next replacement of the branch bridge 601.

[0037] Working principle: During the wire drawing process, the equipment pre-installs the replacement mold 11 to be filled on the locking post 12. Then, the operator holds the wrench 401 to operate the torque column 4 to twist and pull. The locking post 12 without the replacement mold 11 is first inserted into the wire drawing hole of the wire drawing mold 9 to remove the old part. Then, the replacement mold 11 with the replacement mold is put into the arc-shaped opening between the clamping plate 2 and the docking plate 201 to install the new part, reducing the time for changing mold parts. The amount of lead blocks to be inserted into the sheet metal shell is selected according to the actual situation of the wire drawing operation. If the wire diameter is relatively large, more lead blocks are inserted to increase the weight of the docking plate 201. The operator flips all the docking plates 201 over through the connecting plate 3. The connecting plate 3 is made of wood to reduce the total weight. The limiting disc fits the clamping plate 2 and the docking plate 201 to lock them firmly, so that the wire drawing mold 9 will not shift in the axial direction. The metal spring 1201 expands outward through its own elasticity. Zhang, the locking post 12 is inserted into the drawing hole of the drawing die 9 and the replacement die 11. The drawing die 9 and the replacement die 11 will be firmly bound to the locking post 12. When the torque cross post 4 flips outward, the screw valve 802 rotates into the torque shaft seat 801 to lock the outer wall of the torque cross post 4. The worker pre-loads the replacement die 11 to be used next time at this station. After the metal wire drawing operation is completed, it passes through the middle of the two arc-shaped sponge blocks 603. The arc-shaped sponge blocks 603 will wipe the liquid on the outside of the metal wire. Every unit of time, the stepper motor 7 will drive the bifurcation bridge 601 to rotate a certain angle. The arc-shaped sponge block 603 can continuously have new areas to contact the metal wire. When the arc-shaped sponge block 603 needs to be replaced, the other bifurcation bridge 601 is rotated to the wiping station. The wiping arc-shaped sponge block 603 is replaced with a new one during this interval and waits for the next replacement of the bifurcation bridge 601.
