DETAILED DESCRIPTION

[0028] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] like Figures 1-6As shown in the figure, the present invention provides a technical solution: a wire walking device for a slow wire cutting machine, which includes a workbench 1, a base 2, a limit slideway 3, a top plate 4, a first servo motor 5, an auxiliary plate 6, an auxiliary table 7, a rack 8, a transfer block 9, a driving gear 10, a connecting plate 11, an assembly plate 12, a wire electrode 13, an adjusting component 14, an air rod 1401, a second motor 1402, a connecting rod 1403, an adapter seat 1404, an auxiliary cylinder 15, a monitoring component 16, a built-in spring 1601, a force sensor 1602, a built-in cylinder 1603, an auxiliary cover 1604, a limit groove 1605, a bottom frame 17, a threaded groove 18, a middle groove 19, an auxiliary component 20, a conduit 2001, an auxiliary frame 2002, a built-in servo motor 2003, a reel 2004, a guide shaft 21, an auxiliary correction component 22, a first guide wheel 2201, a threaded rod 2202, an electric push rod 2203, a second guide wheel 2204, a winding motor 23, a liquid storage frame 24 and a stop rod 25. Bases 2 are provided on both sides of the workbench 1, and a limit slideway 3 is installed on the top of the base 2. The base 2 and the limit slideway 3 are of an integrated structure, and the cross-section of the limit slideway 3 is in a "U" shape. An auxiliary plate 6 is slidably arranged inside the limit slideway 3, and a rack 8 is installed on the top of the auxiliary plate 6. There are two groups of the auxiliary plate 6 and the rack 8, and the two groups of racks 8 are symmetrically arranged on both sides of the driving gear 10. A top plate 4 is installed on the top of the driving gear 10. A stop rod 25 is snap-fitted on the outer surface of the rear side of the connecting plate 11. When the wire walking device is not in use, it can be snap-fitted on one side of the connecting plate 11 through the design of the stop rod 25, preventing the auxiliary plate 6 from moving inward and reducing potential safety hazards. There are two groups of the auxiliary plate 6, the auxiliary table 7 and the rack 8, and the structures of the two groups of the auxiliary plate 6, the auxiliary table 7 and the rack 8 are exactly the same. An auxiliary table 7 is slidably arranged between the two groups of limit slideways 3. A collection plate 12 is installed on the outer surface of one side of the auxiliary table 7 close to the auxiliary plate 6, and the end of the collection plate 12 is fixedly connected to the auxiliary plate 6. The driving gear 10 is meshed with the outer surface of the rack 8, and a first servo motor 5 is installed in the middle of the bottom of the driving gear 10. Through the design of the first servo motor 5, the driving gear 10 can be driven to rotate. By rotating the driving gear 10, the two groups of racks 8 meshed with the driving gear 10 and the auxiliary plates 6 connected to the racks 8 can be synchronously driven to move, so that the bottom of the auxiliary plate 6 can slide horizontally inside the limit slideway 3, facilitating equidistant cutting operations from both sides according to the requirements of processing parts cutting. One side outer surface of the auxiliary plate 6 is connected with a transfer block 9, and a connecting plate 11 is installed on the outer surface of the transfer block 9. A winding motor 23 is arranged in the middle of one side of the connecting plate 11, and a wire electrode 13 is wound on the output end of the winding motor 23 through a drive shaft. An adjusting component 14 for controlling the tension of the wire electrode 13 is installed at the bottom of the connecting plateA second motor 1402 is installed in the middle of one side of the connecting seat 1404, and an auxiliary cylinder 15 is installed at the output end of the second motor 1402. The electrode wire 13 can be wound up by the design of the winding motor 23. The operator first winds the electrode wire 13 around the outer surface of the auxiliary cylinder 15, and then winds it around the outside of the guide shaft 21 again. The end of the electrode wire 13 is fixed to the reel 2004. The above-mentioned wire walking facilitates the winding and reeling of the electrode wire 13, which is beneficial for wire walking cutting. When the electrode wire 13 becomes loose after multiple uses, the design of the air rod 1401 can drive the connecting seat 1404 to adjust its height up and down, so as to adjust the distance between the electrode wire 13 wound on the outer surface of the drive shaft and the auxiliary cylinder 15. In this way, the slack state of the electrode wire 13 can be controlled to avoid the problem of cutting offset or inability to complete the cutting operation due to the loose electrode wire 13. A guide shaft 21 is installed at one end of the connecting rod 1403, and an auxiliary electrode is provided on the outer surface of the guide shaft 21. The auxiliary correction component 22 for correcting the position of the wire 13 includes a first guide wheel 2201, a threaded rod 2202, an electric push rod 2203, and a second guide wheel 2204. The internal thread of the first guide wheel 2201 is installed with the threaded rod 2202, and the end of the threaded rod 2202 is rotatably provided with the second guide wheel 2204. The electric push rod 2203 is installed on the outer surface of one side of the first guide wheel 2201. The electrode wire 13 is wound and introduced between the first guide wheel 2201 and the second guide wheel 2204. The distance between the first guide wheel 2201 and the second guide wheel 2204 can be controlled by rotating the threaded rod 2202 clockwise or counterclockwise according to the diameter of the electrode wire 13, facilitating adaptive positioning of the electrode wire 13. This facilitates adjusting the position of the electrode wire 13 relative to the guide shaft 21 between the first guide wheel 2201 and the second guide wheel 2204 during the routing of the electrode wire 13 through the design of the electric push rod 2203, thereby preventing the cutting area from shifting when the electrode wire 13 is used to cut the workpiece.

[0030] like Figure 3 and Figure 4As shown, a connecting rod 1403 is fixedly installed on one side of the outer surface of the connecting seat 1404 by screws, and a monitoring component 16 for auxiliary monitoring of the tension state of the electrode wire 13 is provided inside the auxiliary cylinder 15, and the monitoring component 16 includes a built-in spring 1601, a force sensor 1602, a built-in cylinder 1603, an auxiliary cover 1604 and a limiting groove 1605. The outer surface of the built-in cylinder 1603 is provided with a built-in spring 1601, a force sensor 1602 is installed in the middle of the outer surface of the built-in cylinder 1603, and an auxiliary cover 1604 is provided on the top of the force sensor 1602. A limiting groove 1605 is provided inside the auxiliary cover 1604. The electrode wire 13 is wound on the outer surface of the auxiliary tube 15 and is limited in the limiting groove 1605 in the appropriate area. When the electrode wire 13 is wound, it will press the auxiliary cover 1604. By pressing the auxiliary cover 1604 and synchronously coordinating the design of the built-in spring 1601 and the force sensor 1602, it is convenient to know the pressure intensity of the electrode wire 13 on the auxiliary cover 1604. Therefore, when the number of electrode wire 13 workpieces increases and the electrode wire 13 becomes loose, the pressure on the auxiliary cover 1604 will be reduced, so that the user can know the usage status of the electrode wire 13 in time, and avoid the electrode wire 13 continuing to cut after being loose, resulting in poor effect in the cutting area.

[0031] like Figure 1 and Figure 5As shown, a central groove 19 is provided in the middle of the auxiliary table 7, a bottom frame 17 is provided at the bottom of the auxiliary table 7, and an auxiliary component 20 for assisting wire cutting is installed inside the bottom frame 17, and two groups of auxiliary components 20 are provided, and the auxiliary component 20 includes a guide tube 2001, an auxiliary frame 2002, a built-in servo motor 2003 and a reel 2004. A threaded groove 18 is provided on one side of the auxiliary table 7 near the central groove 19, a guide tube 2001 is provided at the bottom of the threaded groove 18, an auxiliary frame 2002 is installed at the end of the guide tube 2001, and a built-in servo motor 2003 is provided in the middle of the auxiliary frame 2002, and a reel 2004 is installed at the output end of the built-in servo motor 2003, and a liquid storage frame 24 is provided at the bottom of the bottom frame 17, and the bottom frame 17 and the liquid storage frame 24 are both hollow structures, and the bottom frame 17 and the liquid storage frame 24 are snap-connected. Since the discharge of the electrode wire 13 must be carried out in a liquid medium with a certain insulating property, when cutting the workpiece, a suitable emulsion is first selected through experiments. The insulating property of the working fluid compresses the discharge channel after breakdown, thereby limiting the discharge to a smaller channel radius. The instantaneous and local high temperature formed melts and vaporizes the metal. After the discharge is completed, the discharge gap is quickly restored to an insulating state. The design of the threaded groove 18 makes it convenient for the operator to thread the water pipe. Emulsion is configured inside the bottom frame 17. The pump body design allows the emulsion in the bottom frame 17 to be transported to the inside of the auxiliary frame 2002. When the emulsion flows through the inside of the auxiliary frame 2002, it can dissipate heat for the built-in servo motor 2003 to avoid poor heat dissipation of the built-in servo motor 2003 when working for a long time. The design of the conduit 2001 allows the emulsion to be sprayed to the auxiliary table 7.

[0032] In summary, if Figures 1-6As shown, the wire-feeding device of the slow-wire cutting machine, when in use, first place the workpiece on the surface of the workbench 1, and then the first servo motor 5 is designed to drive the driving gear 10 to rotate, and the rotation of the driving gear 10 can synchronously drive the two sets of racks 8 meshing with the driving gear 10 and the auxiliary plate 6 connected to the rack 8 to move synchronously, so that the bottom of the auxiliary plate 6 can slide horizontally inside the limiting slide 3, which is convenient for equidistant cutting operations from both sides according to the cutting requirements of the workpiece. The electrode wire 13 can be wound up by the design of the winding motor 23. The operator first winds the electrode wire 13 around the outer surface of the auxiliary cylinder 15, and then winds it around the outside of the guide shaft 21 again. The end of the electrode wire 13 is fixed to the reel 2004, and through the above-mentioned walking The wire is convenient for reeling and winding the electrode wire 13, which is beneficial for wire cutting. When the electrode wire 13 becomes loose after repeated use, the design of the gas rod 1401 can drive the connecting seat 1404 to adjust the height up and down, so as to adjust the distance between the electrode wire 13 wound on the outer surface of the drive shaft and the auxiliary cylinder 15. In this way, the relaxation state of the electrode wire 13 can be controlled to avoid the problem of cutting deviation or inability to complete the cutting during the cutting operation of the electrode wire 13 after relaxation. By winding the electrode wire 13 on the outer surface of the auxiliary cylinder 15 and limiting it in the limiting groove 1605 in the appropriate area, the auxiliary cover 1604 will be pressed when the electrode wire 13 is wound, and the pressure on the auxiliary cover 1604 is synchronized with the built-in spring 1601. The design and the cooperation of the force sensor 1602 facilitate the acquisition of the pressure strength of the electrode wire 13 on the auxiliary cover 1604, so that when the number of workpieces processed by the electrode wire 13 increases and the electrode wire 13 becomes loose, the pressure on the auxiliary cover 1604 will be reduced, so that the user can timely acquire the use status of the electrode wire 13, and avoid the electrode wire 13 continuing to cut after it is loose, resulting in poor cutting effect in the cutting area. Then, the electrode wire 13 is wound and introduced between the first guide wheel 2201 and the second guide wheel 2204, and the distance between the first guide wheel 2201 and the second guide wheel 2204 can be controlled by rotating the threaded rod 2202 clockwise or counterclockwise according to the diameter of the electrode wire 13, so as to facilitate the adaptive limitation of the electrode wire 13, which is beneficial when the electrode wire 13 is arranged. The position of the electrode wire 13 with respect to the guide shaft 21 is adjusted and limited between the first guide wheel 2201 and the second guide wheel 2204 by the design of the electric push rod 2203, so as to avoid the cutting area being offset when the workpiece is cut using the electrode wire 13. In addition, since the discharge of the electrode wire 13 must be carried out in a liquid medium with a certain insulating property, when cutting the workpiece, a suitable emulsion is first selected through experiments. The insulating property of the working fluid causes the discharge channel to be compressed after breakdown, thereby confining the discharge within a smaller channel radius. The instantaneous and local high temperature formed melts and vaporizes the metal, and the discharge gap is quickly restored to an insulating state after the discharge ends. The design of the threaded groove 18 facilitates the operator to threadably install the water pipe. The emulsion is configured inside the bottom frame 17.The pump body design allows the emulsion in the bottom frame 17 to be transported to the interior of the auxiliary frame 2002. When the emulsion flows through the auxiliary frame 2002, it can dissipate heat for the built-in servo motor 2003, thus preventing the built-in servo motor 2003 from working for a long time and causing poor heat dissipation. The design of the conduit 2001 allows the emulsion to be sprayed to the auxiliary table 7 to assist in the cutting process.
