Description

Technical Field

[0001] The invention belongs to the technical field of cutting processing, and relates to a wire cutting device, and in particular to a wire cutting processing device and a cutting wire replacement method. Background Art

[0002] Wire cutting is the abbreviation of wire cutting, which refers to cutting raw materials with linear tools. It belongs to the category of electrical processing. Wire cutting machine is a common equipment in wire cutting processing devices. Wire cutting technology and wire cutting machine tools are being widely used in all walks of life. Wire cutting machine is mainly composed of CNC system, high-frequency power supply, wire storage mechanism, wire rack moving device, XY workbench and other groups. Its working principle is based on the discharge principle of electric spark. Through the workpiece connected to the positive electrode of the pulse power supply, molybdenum wire or copper wire is used as the cutting metal wire and connected to the negative electrode of the high-frequency pulse power supply as the tool electrode, and the processed parts are cut by spark discharge. The pulse power supply provides processing energy, and under the action of the electric field, the cathode and anode surfaces are bombarded by electron flow and ion flow respectively, forming an instantaneous high-temperature heat source to melt and vaporize the local metal. The melted and vaporized workpiece material is thrown out of the discharge channel under the combined action of thermal expansion and working fluid stamping, thereby completing a spark discharge process. With the continuous action of the pulse, the workpiece is gradually cut into precise, small and complex parts.

[0003] The utility model patent with application number 202022878800.7 discloses a wire cutting machine for bolt production, which includes a machine body, an opening and closing assembly is arranged on the surface of the machine body, a wire storage mechanism is fixedly installed on the top side of the machine body, a workbench is fixedly installed on the top side of the machine body, a clamp assembly is arranged on the top of the workbench, a protective assembly is arranged around the clamp assembly, a pumping assembly is arranged inside the workbench, a cutting column is fixedly installed on one side of the workbench, an upper wire cutting frame is movably installed on the surface of the cutting column, a lower wire cutting frame is fixedly installed on the bottom of the upper wire cutting frame, a cutting wire is fixedly installed between the upper wire cutting frame and the lower wire cutting frame, and a support assembly is fixedly installed on the bottom of the machine body. Fix the cross plate on the pillars on the top of the workbench, and fix the cross plate through the fixing screw holes and fixing bolts according to actual needs. Then place the components to be processed on the inside of the clamp block, and then twist the extrusion bolts on the top of the clamp block to push the fixing pad to fix and cut it. If you need to change the angle, you can twist the extrusion bolts and remove the fixing pad to adjust it, avoiding the inconvenience of adjustment caused by different sizes of workpieces, improving efficiency, and reducing production costs.

[0004] The above-mentioned wire cutting machine for bolt production not only solves the problem of matching the size and thickness of the fixture with the workpiece, but also solves the safety problems such as sparks and debris splashing caused by high temperature during cutting. However, when the existing cutting machine is in use, due to its cutting characteristics, the cutting line will generate high temperature due to cutting, and cutting will also generate high-temperature sparks; and by setting up a protective component, it can only block the high-temperature sparks generated by cutting, but cannot solve the problem of high cutting line temperature caused by cutting. For this reason, the utility model patent with application number 202323136796.7 also discloses a wire cutting wire adjustment tool, which includes a base, a vertical plate fixedly installed on the top of the base, a lower bracket fixedly installed on the side of the bottom end of the vertical plate, a guide rod fixedly installed on the top of the vertical plate, a threaded rod rotatably connected at the center of the top of the vertical plate, and an upper bracket slidably connected on the surface of the guide rod. The right ends of the lower bracket and the upper bracket are fixedly installed with mounting tubes, a socket is opened in the middle of the mounting tube, and an extrusion column is inserted inside the mounting tube. In addition, a fixing plate is fixedly installed at the bottom of the right end of the upper bracket, an annular cover is fixedly installed at the other end of the fixing plate, a liquid inlet pipe is fixedly installed on the surface of the annular cover, and a spray hole array is opened at the bottom of the annular cover. The annular cover is sleeved on the outside of the cutting line; cooling water is sprayed onto the surface of the cutting line through the spray holes to ensure the heat dissipation effect of the cutting line and prevent the cutting line from being overheated.

[0005] In summary, in addition to the problems of matching with tools, safety protection against splashing, and safety problems caused by high temperatures of the cutting wire, the existing wire cutting processing device also faces the problem of replacing the cutting wire due to damage or changes in processing requirements in actual use. In the prior art, when replacing the cutting wire, wire extraction (i.e., taking out the cutting wire) is very cumbersome, and it is usually pulled out little by little by hand. However, in the process of slowly collecting the cutting wire from the wire storage mechanism, it is not convenient to replace the cutting wire because the cutting wire is very sharp, and there are residual waste chips on the cutting wire after cutting, and the temperature is high. How to replace the cutting wire safely, conveniently, and quickly is a new problem that needs to be solved urgently. Summary of the invention

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention. Example 1

[0043] This embodiment provides a wire cutting processing device for wire cutting processing. It includes a machine tool body 1, which can adopt the existing structure; the bottom surface of the machine tool body 1 is placed on a foundation such as the ground, and a numerical control system and a high-frequency power supply are arranged in the machine tool body 1. The top of the machine tool body 1 is fixedly connected with a wire storage mechanism 2, a wire clamp moving device 3 and a coordinate workbench 4. The wire storage mechanism 2 is mainly used to store the cutting wire 7, and the cutting wire 7 can be wound on it. It can adopt the existing wire storage mechanism 2. The wire clamp moving device 3 is mainly used to install the cutting wire 7 and adjust the position of the cutting wire 7. The wire clamp moving device 3 can slide on the machine tool body 1 as a whole; it includes an upper wire cutting frame, and a lower wire cutting frame is fixedly installed at the bottom of the upper wire cutting frame. The cutting wire 7 passes between the upper wire cutting frame and the lower wire cutting frame and is wound on the wire storage mechanism 2, and the workpiece to be cut is clamped in the area between the upper wire cutting frame and the lower wire cutting frame, and the cutting wire 7 can cut it; the wire clamp moving device 3 can also adopt the existing structure. The coordinate workbench 4 is used to support and fix the workpiece, and the existing technology can also be adopted. The machine tool body 1, the wire storage mechanism 2, the wire rack moving device 3, the coordinate workbench 4 and the cutting wire 7 cooperate to realize the cutting function.

[0044] On the basis of the above structure, a cutting mechanism 5 is further included, and the cutting mechanism 5 is mainly used to cut the cutting wire 7 on the wire storage mechanism 2, so as to facilitate the replacement of the cutting wire.

[0045] The cutting mechanism 5 specifically comprises a moving part, which comprises a fixed plate 501 fixedly connected to the machine tool body 1, and a tangent roller 504 mounted on the fixed plate 501. The fixed plates 501 are provided with two pieces, and the tangent roller 504 is located between the two fixed plates 501 and can rotate around its axis between the two fixed plates 501. A cutter disc 507 is provided inside the tangent roller 504, and the axis of the cutter disc 507 coincides with the axis of the tangent roller 504, and the cutter disc 507 rotates together with the tangent roller 504. A plurality of cutters 508 are evenly hinged on the cutter disc 507 along the circumference of the cutter disc 507, and each cutter 508 can rotate independently on the cutter disc 507. The other end of the cutter 508 is connected to a spring 518, and the other end of the spring 518 is fixed on the cutter disc 507; when the cutting line 7 does not need to be replaced, the cutter 508 is stored in the cutting roller 504 under the pulling force of the spring 518; when the cutting line 7 needs to be replaced, the free end of the cutter 508 can be thrown out of the cutting roller 504 under the action of centrifugal force, and the cutting line 7 on the wire storage mechanism 2 is cut. To meet the above requirements, the spring 518 can be calculated and determined by a person skilled in the art according to the weight of the cutter 508, the centrifugal force, etc., and its elastic coefficient can be produced and manufactured without creative labor. In order for the free end of the cutter 508 to be thrown out of the cutting roller 504 smoothly, a notch 519 is required to be opened on the outer wall of the cutting roller 504 corresponding to the position of each cutter 507, and the free end of the cutter 508 can be thrown out of the cutting roller 504 through the notch 519 under the action of centrifugal force. In addition, when cutting the cutting line 7, in order to be able to cut the cutting line 7 on the wire storage mechanism 2 in an orderly manner (from the outside to the inside) and not cause damage to the structure of the wire storage mechanism 2 during the cutting process, the length L between the rotation axis of the cutter 508 and the end of the cutter 508 is adapted to the minimum distance between the rotation axis of the cutter 508 and the cylindrical surface of the wire storage mechanism 2.

[0046] The working process of the wire cutting processing device is as follows: during wire cutting, the cutting wire 7 passes through the wire rack moving device 3 and is wound and set on the wire storage mechanism 2, and the wire cutting processing device performs wire cutting processing on the workpiece. This is the prior art. When the cutting wire needs to be replaced, the motor 502 is installed to start, and the wire cutting roller 504 starts to rotate; when the wire cutting roller 504 just starts to rotate, the centrifugal force on the cutter 508 is small and is not enough to pull the spring 518; as the speed of the wire cutting roller 504 increases, the centrifugal force on the cutter 508 increases. When the centrifugal force is greater than the elastic force of the spring 518, the free end of the cutter 508 will gradually be thrown out of the wire cutting roller 504, and the part of the cutter 508 that extends out of the wire cutting roller 504 can be pulled on the wire storage mechanism 2. The cutting line 7 is cut; as the surface cutting line 7 is cut, the rotation speed of the cutting roller 504 continues to increase gradually, and the portion of the free end of the cutter 508 that is thrown out of the cutting roller 504 gradually increases. The free end of the cutter 508 can cut the deeper cutting line 7 on the wire storage mechanism 2 until the cutting line 7 is cut. Finally, the cutting line 7 is clamped by special tools such as pliers, the cutting line 7 wound on the wire storage mechanism 2 is removed, and a new cutting line is replaced to complete the replacement of the cutting line 7.

[0047] By driving the tangent roller 504 to rotate, the cutter 508 is thrown out of the tangent roller 504, and the cutter 508 can cut the cutting wire 7 wound on the wire storage mechanism 2; by controlling the rotation speed of the tangent roller 504, the extension amount of the cutter 508 thrown out of the tangent roller 504 can be effectively controlled, so that the cutting wire 7 wound on the wire storage mechanism 2 at different radial positions can be cut, and by controlling the throw-out amount of the cutter 508 and the length of the cutter 508, the cutter 508 can be effectively prevented from scratching or damaging the wire storage mechanism 2 during the cutting process; after the cutting wire 7 is cut, it can be conveniently and quickly replaced with the assistance of tools such as pliers. This embodiment can effectively solve the inconvenience and unsafety caused by the sharpness of the cutting wire 7 and the residual waste in the replacement process, greatly improve the convenience and safety of the replacement of the cutting wire 7, and will not cause scratches or damage to the wire storage mechanism 2 during the cutting process, and will not shorten the service life of the wire storage mechanism 2 or even the entire wire cutting processing device. Example 2

[0048] Although the first embodiment solves the problem of replacing the cutting line 7, some cutting debris usually adheres to the cutting line 7 during the replacement process, so the cutting line 7 needs to be cleaned. Therefore, the present embodiment adds a related structure for cleaning the cutting line 7 on the basis of the first embodiment, specifically:

[0049] A mounting frame 505 is also mounted on the fixed plate 501. The mounting frame 505 is located above the tangent roller 504, and the cutting knife 508 will not cut the mounting frame 505 after it is thrown out of the tangent roller 504. A wire component is arranged in the middle of the mounting frame 505, and the wire component is mainly used to guide and pass the cutting wire 7. The wire component includes a guide plate 511 and a cleaning limit ball 512, and the cleaning limit ball 512 can be used to clean the cutting wire 7. The guide plate 511 is fixedly connected to the inner wall of one side of the mounting frame 505, and the cleaning limit ball 512 is rotatably connected between the inner walls on both sides of the guide plate 511. After the cutting wire 7 passes through the guide groove on the cleaning limit ball 512 and then passes through the wire rack moving device 3, it is wound and arranged on the wire storage mechanism 2; and in the process of the cutting wire 7 moving, the cutting wire 7 is cleaned and the cutting debris adhering to the cutting wire 7 is wiped off.

[0050] The cutting line passes through the guide plate 511 and the cleaning limit ball 512 , and the cutting line 7 can be cleaned by the cleaning limit ball 512 . Example 3

[0051] In the process of replacing the cutting wire 7, in addition to the problem that the cutting wire 7 is sharp and has debris attached to it, there is often a problem that the temperature of the cutting wire is high after cutting, so it is necessary to cool the cutting wire 7. To this end, this embodiment is based on the above embodiment, and adds a related structure for cooling the cutting wire 7, specifically:

[0052] The cutting mechanism 5 also includes a cooling component for cooling the cutting line 7, which includes a delivery pump 513, a delivery pipe 514, a fixed pipe 515 and two nozzles 516. The installation positions of the delivery pump 513 and the delivery pipe 514 can be determined according to actual conditions, as long as they do not affect the rotation of the cutting roller 504, or the delivery pump 513, the delivery pipe 514 and the fixed pipe 515 are disassembled so as not to affect the rotation of the cutting roller 504. The delivery pump 513 can be connected to the installation frame 505 or the cutting roller 504, one end of the delivery pipe 514 is connected to the water source, the other end of the delivery pipe 514 is connected to the input end of the delivery pump 513, the output end of the delivery pump 513 is connected to one end of the fixed pipe 515, and the other end of the fixed pipe 515 is connected to the nozzle 516. The two nozzles 516 are distributed on both sides of the cutting line 7 in a left-right and front-back manner.

[0053] When the cutting line needs to be cooled, the delivery pump 513 is turned on, and the cooling water is sprayed on the cutting line 7 through the transmission pipe 514, the delivery pump 513, the fixed pipe 515 and the nozzle 516. Firstly, the cutting line 7 is cooled, and secondly, the cutting line 7 is flushed to flush away the chips adhered to the cutting line 7; thereby, the subsequent replacement of the cutting line 7 is more convenient.

[0054] The water source can be an external water source (such as tap water) or can be from a wire cutting processing device. For this reason, preferably, a storage component for collecting and storing water is also provided in the tangent roller 504. The storage component includes a partition 509, a water leakage net 506 and a plurality of water leakage grooves 510. Both ends of the partition 509 and the water leakage net 506 are fixedly connected between the inner walls on both sides of the tangent roller 504, the water leakage net 506 is located directly above the partition 509, and a water storage area is formed between the water leakage net 506 and the partition 509; a plurality of water leakage grooves 510 are all provided on the outer surface of the water leakage net 506. One end of the transmission pipe 514 extends into the water storage area, and the other end of the transmission pipe 514 is connected to the delivery pump 513. When the delivery pump 513 is connected to the mounting frame 505, the transmission pipe 514 needs to be disassembled from the delivery pump 513 before the tangent roller 504 needs to be rotated; when the delivery pump 513 is connected to the tangent roller 504, the fixing pipe 515 needs to be disassembled from the delivery pump 513 before the tangent roller 504 needs to be rotated.

[0055] During spraying, the water stored in the cutting roller 504 will be sprayed out through the transmission pipe 514, the delivery pump 513, the fixed pipe 515 and the nozzle 516, and sprayed on the cutting line 7; and the water sprayed on the cutting line 7 will fall down, pass through the leakage trough 510 and the leakage net 506, and finally enter the water storage area for recovery and storage, and the leakage net 506 also filters the spraying water to place the chips into the water storage area.

[0056] In addition, the tangent line is usually replaced only when the line breaks during the line cutting process or after the line is cut. Therefore, before the tangent roller 504 is rotated, water is usually stored in the water storage area of ​​the tangent roller 504. Therefore, the water can also be thrown out during the rotation of the tangent roller 504, thereby acting on the cutting area of ​​the cutting line, firstly, effectively cooling the cutting area, and secondly, flushing the debris generated by the cutting, thereby improving the cutting effect and efficiency of the cutting line 7.

[0057] In addition, a plurality of cutter discs 507 may be arranged in the tangent roller 504 along its axial direction, and each cutter disc 507 is provided with a through hole 517 , and each independent water storage area is connected through the through hole 517 on each cutter disc 507 .

[0058] The water at the bottom of the storage box is transferred through the transfer pipe 514 by the transfer pump 513, and the surface of the cutting line 7 can be cooled and cleaned through the fixed pipe 515 and the nozzle 516. The water falls into the space between the leaking net 506 and the partition 509 through the leaking net 506 and the leaking groove 510 and is stored. The setting of the cutting mechanism can facilitate the user to disassemble the discarded cutting line and clean and cool the cutting line. Example 4

[0059] On the basis of the above embodiment, in order to better drive the tangent roller 504, the cutting mechanism 5 also includes a power component, which includes two synchronous wheels 503 and a mounting motor 502, and the mounting motor 502 is fixedly connected to the outer surface of one side of the fixed plate 501; one of the synchronous wheels 503 is fixedly sleeved on the output end of the mounting motor 502, and the other synchronous wheel 503 is fixedly sleeved on the end of the tangent roller 504 and rotates synchronously with the tangent roller 504, and the two synchronous wheels 503 are mutually transmitted through a synchronous belt.

[0060] When the tangent roller 504 needs to rotate, the installation motor 502 will drive the tangent roller 504 to rotate through the synchronous belt and the synchronous wheel 503. Example 5

[0061] On the basis of the above embodiment, a protection mechanism 6 for preventing the splashing of cutting debris is further included. The protection mechanism 6 includes two groups of adjustment components and two groups of cover components. The cover components are used to cover the cutting area to prevent the splashing of cutting debris; the adjustment components can adjust the position of the cover components. Each group of adjustment components is installed on the wire rack moving device 3, and each group of cover components is installed on the adjustment components.

[0062] The cover component includes a fixed electric telescopic rod 603, a protective cover 604, a vacuum cleaner 605 and a cooling fan 606.
