Description

Technical Field

[0001] The invention relates to the technical field of electric spark cutting, in particular to a numerically controlled electric spark ring cutting device. Background Art

[0002] Rings generally refer to circular objects with hollow interiors. When manufacturing small batches of rings with high precision requirements, an EDM wire cutting machine can be used for production. The EDM wire cutting machine connects the workpiece to the positive electrode of the pulse power supply, uses molybdenum wire or copper wire as the cutting wire, connects the wire to the negative electrode of the high-frequency pulse power supply as the tool electrode, and uses spark discharge to cut the processed parts. The pulse power supply provides processing energy. During the processing, a special wire cutting working fluid is used to remove the debris generated during the processing. Under the action of the electric field, the cathode and anode surfaces are bombarded by electron flow and ion flow respectively, and an instantaneous The high-temperature heat source melts and vaporizes the local metal. The vaporized working fluid and workpiece material steam expand rapidly in an instant. Under the combined effect of this thermal expansion and the working fluid stamping, the melted and vaporized workpiece material is thrown out of the discharge channel, thus completing a spark discharge process. After the excess working fluid cools down, it is carried into the water tank by the melted and vaporized workpiece debris. The working fluid will be pumped back into the machine body for filtration and reuse. When the next pulse arrives, the above spark discharge process will be repeated to cut the workpiece into shape. The wire EDM can control the cutting trajectory of the metal wire through CNC programming.

[0003] When cutting small batches of rings, operators can use a cutting machine to cut the outer contour of the ring on the steel ingot, so that the steel ingot is cut into multiple columns, and then cut the columns horizontally to cut out the thickness of the ring. Then, the ring is opened to obtain the finished ring. However, in this process, due to the small batch size, it is basically necessary to manually adjust the position of the workpiece to be cut and then clamp it, which is inconvenient.

The ends of the sliding bars are connected to a fixing plate, and the fixing plate is connected to the movable end of the intelligent push rod; the top surfaces of the sliding bars are higher than the top surfaces of the two arms of the U-shaped frame. When the ingot is placed on the two arms of the U-shaped frame, it is supported by the sliding bars.

[0010] Furthermore, the driving mechanism includes two electric push rods, which are respectively located at the diagonal corners of the water tank. The movable ends of the electric push rods are fixedly connected to the top surface of the U-shaped frame. An L-shaped plate is also fixed on the top surface of the U-shaped frame. One end of a connecting rope is fixedly connected to the L-shaped plate, and the other end of the connecting rope bypasses a fixed rod and is fixedly connected to the top surface of a slider. The fixed rod is located at the top of the mounting plate, and the mounting plate is fixed on the top surface of the water tank; the slider is inside the guiding groove on the top surface of the pallet and is connected to one end of a return spring, and the other end of the return spring is fixed on the inner wall of the guiding groove; a torsion spring is arranged on the outer side wall of the intelligent push rod, and the torsion spring is fixedly connected to the inner wall of the circular hole of the mounting plate.

[0011] Furthermore, a limiting groove is opened on the outer side wall of the fixed rod, and the connecting rope is located inside the limiting groove.

[0012] Furthermore, a set of rotating rollers is arranged beside the opposite side walls of the water tank in a staggered manner. The set of rotating rollers includes an upper rotating roller and a lower rotating roller connected by a transmission belt. At both ends of the upper rotating roller and the lower rotating roller, there are connecting plates, and the connecting plates are fixed on the water tank; the two arms of the U-shaped frame are respectively located inside the corresponding transmission belts and are fixedly connected to the inner side wall of one of the transmission belts.

[0014] Furthermore, the middle part of the bottom surface of the abutment plate is rotatably connected to one end of a rotating rod, the other end of the rotating rod is rotatably connected to a scraper, the scraper is in contact with the top surface of the filter screen, and an outlet is opened at the end of the water tank.

[0015] Furthermore, a frosted layer is provided on the fixing side of the abutment plate.

[0016] Compared with the prior art, the above technical solution adopted by the present invention has the following advantages:

[0017] 1. Place the steel ingot horizontally on the clamping mechanism for clamping, then start the machine to cut the steel ingot, cut out the outer contours of different rings on the steel ingot, move the molybdenum wire out of the steel ingot, and then start the driving mechanism to drive the clamping mechanism and the steel ingot to rotate synchronously and move the resistance mechanism toward the clamping mechanism, so that the steel ingot is clamped by the resistance mechanism and the clamping mechanism, start the machine again to make the molybdenum wire cut the steel ingot, cut out the thickness of the ring, and then turn the steel ingot over so that the machine can cut out the outer contour and thickness of the ring at one time, so that users can more conveniently produce rings in batches.

[0018] 2. Place the steel ingot horizontally on the two arms of the U-shaped frame. The intelligent push rod contacts the steel ingot through the fixed plate, and contacts the steel ingot against the two upright rotating plates to clamp and fix the steel ingot. Start the machine body to control the molybdenum wire to enter the upper part of the support plate through the entry groove to cut the steel ingot. The cut cylinder slides down onto the support plate. After the molybdenum wire moves out of the steel ingot, the intelligent push rod resets to move the steel ingot. The driving mechanism pulls the connecting rope, so that the connecting rope pulls the slider to drive the support plate to move up. The two rotating plates automatically stick to the U-shaped frame due to the resetting elastic force of the torsion spring. The support plate pushes the cylinder back into the steel ingot. Then the intelligent push rod starts again to contact the steel ingot with the ends of the two rotating plates. At this time, the connecting rope continues to pull, driving the slider to press the rebound spring, so that the support plate drives one side of the U-shaped frame to tilt up. The connecting rope pulls the support plate and the U-shaped frame to rotate through the slider, thereby rotating the steel ingot.

[0019] 3. The U-shaped frame is driven downward by two electric push rods, so that the U-shaped frame drives the L-shaped plate downward, and the L-shaped plate pulls one end of the connecting rope downward. At this time, the other end of the connecting rope pulls the slider upward. At the same time, the L-shaped plate moves downward to pull the connecting rod to make the abutment plate slide toward the supporting plate. Then the abutment plate, the supporting plate and the U-shaped frame clamp the rotated ingot. At the same time, the U-shaped frame moves downward, so that the U-shaped frame pulls the two transmission belts to rotate. The filter screens on the two transmission belts move upward to the water surface due to the rotation of the transmission belts, which is convenient for users to clean the metal debris generated by cutting on the filter screen;

[0020] 4. The drive mechanism pulls the back plate to move and move the filter upward. The scraper is tilted at a larger angle due to the upward movement of the filter and the push of the back plate. The rotating rod drives the scraper to scrape the filter, and the metal debris on the filter is scraped to the water tank outlet through the scraper. Therefore, the debris on the filter can be automatically cleaned, which is convenient for users. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0031] Example 1

[0032] See alsoFigure 1-8 As shown, this embodiment provides a CNC electric spark ring cutting device, including a body 100, a water tank 110 is arranged on one side of the body, a clamping mechanism 200 is installed on the top of the water tank 110, a resistance mechanism 400 is arranged next to the clamping mechanism 200, a driving mechanism 300 is installed inside the water tank, and an entry groove 111 is opened on the connection side between the water tank and the body;

[0033] The clamping mechanism 200 includes a U-shaped frame 210, the bottom surface of which is fixedly connected to four support rods 211, a support plate 220 is arranged below the U-shaped frame 210, the bottom surface of the support plate 220 is provided with four sliding holes 221, and the four support rods 211 are respectively slidably embedded in the four sliding holes 221, so that the top surface of the support plate 220 can be slidably embedded in the U-shaped frame 210, the top surface of the water tank is fixedly connected to a mounting plate 120, the mounting plate 120 is provided with a circular hole 121, and the circular hole 121 is rotatably connected to the inside of the intelligent push rod 230, the top surfaces of the two arms of the U-shaped frame 210 are both rotatably connected to a rotating plate 240, the outer root of the rotating plate 240 is provided with a resistance bar 241, and the resistance bar 241 is also fixed to the top surfaces of the two arms of the U-shaped frame 210, and the two sides of one end of the support plate 220 are respectively fixedly connected with a drawstring 223, and the drawstring 223 bypasses the end of the U-shaped frame 210 and is fixedly connected to the corresponding outer middle of the rotating plate 240.

[0034] The steel ingot is placed horizontally on the U-shaped frame 210, and the intelligent push rod 230 is used to contact the steel ingot with two rotating plates 240 to fix the steel ingot. Then the electric spark cutting machine moves the molybdenum wire to cut the steel ingot, so that a cylinder is cut on the top surface of the steel ingot to make a ring. The cut multiple cylinders slide off from the cutting groove formed by the molybdenum wire cutting trajectory and fall onto the support plate 220. The support plate 220 is driven upward by the driving mechanism 300 to be embedded in the U-shaped frame 210, and the cut cylinder is stuffed back into the groove cut by the steel ingot. Then the driving mechanism 300 drives the support plate 220 and the U-shaped frame 210 to rotate, and the contact mechanism 400 moves toward the support plate 220 to clamp the steel ingot vertically, and the electric spark cutting machine 100 is started again to move the molybdenum wire and cut the steel ingot again, so that the cylinder inside the steel ingot is cut into a circular plate, and the circular plate is punched to obtain a ring.

[0035] Based on the above scheme, when cutting the steel ingot, the user can quickly cut the outer contours of different rings on the same steel ingot, and then automatically flip the steel ingot over and cut the steel ingot again according to the thickness of the ring, thereby facilitating the user to batch produce rings and adjust the position of the steel ingot.

[0036] A torsion spring is provided at one end of each of the two rotating plates 240, and the torsion spring is fixedly connected to the top surface of the U-shaped frame 210. A side plate is provided on the bottom surface of the support plate 220, and a sliding hole 221 is provided on the side plate, and the top of the support plate 220 can be embedded in the U-shaped frame 210. When the support plate 220 is not embedded in the U-shaped frame 210, the support plate 220 pulls the two rotating plates 240 upright through the pull belt 223 to abut against the adjacent abutment bar 241, thereby increasing the contact area between the rotating plate 240 and the steel ingot, and clamping the steel ingot more firmly.

[0037] A notch 213 is formed at one end of both arms of the U-shaped frame 210 , and the two drawstrings 223 are located inside the corresponding notches 213 . The notches 213 are used to limit the drawstrings 223 to prevent the two drawstrings 223 from being separated from the two arms of the U-shaped frame 210 .

[0038] The top surfaces of the two arms of the U-shaped frame 210 are provided with a slide groove 212, the movable end of the smart push rod 230 is fixedly connected to a fixed plate 231, and both ends of the fixed plate 231 are fixedly connected to a slide bar 232, the two slide bars 232 are respectively slidably connected to the corresponding inside of the slide groove 212, the top surface of the slide bar 232 is higher than the top surface of the two arms of the U-shaped frame 210, when the steel ingot is placed above the two arms of the U-shaped frame 210, part of the steel ingot is supported by the slide bar 232; the fixed plate 231 pushes the steel ingot and the two upright rotating plates 240 The steel ingot is fixed by the friction. When the steel ingot needs to be rotated, the support plate 220 is moved upward by the driving mechanism 300 to relax the two pull straps 223. The smart push rod 230 will reset first, so that the two reset slide bars 232 drive the steel ingot to move part of the position. The two rotating plates 240 are attached to the top surface of the U-shaped frame 210 due to the reset elastic force of the torsion spring. The smart push rod 230 is started again, so that the fixed plate 231 pushes the steel ingot to collide with the ends of the two rotating plates 240. Therefore, the two rotating plates 240 are not easy to block the movement of the molybdenum wire.

[0039] The driving mechanism 300 includes two electric push rods 310, which are fixed at the corners of the water tank 110 respectively. A U-shaped frame 320 is arranged below the two electric push rods 310. The top surface of the U-shaped frame 320 is fixedly connected to the movable ends of the two electric push rods 310, and the top surface of the U-shaped frame 320 is fixedly connected to an L-shaped plate 330. The top of the mounting plate 120 is fixedly connected to a fixing rod 250. The top surface of the support plate 220 is provided with a guide groove 222, and a slider 260 is slidably connected inside the guide groove 222. The slider 260 One end is fixedly connected with a rebound spring 261, which is fixed to the inner wall of the guide groove 222. The top surface of the slider 260 is fixedly connected with a connecting rope 262, and one end of the connecting rope 262 passes through the fixing rod 250 and is fixedly connected to the top of the L-shaped plate 330. The outer wall of the smart push rod 230 is provided with a torsion spring, which is fixedly connected to the inner wall of the circular hole 121. The two electric push rods 310 are arranged diagonally with the center of the water tank 110, so that when the two electric push rods 310 are started, the U-shaped frame 3 The U-shaped frame 320 moves more evenly, and the two electric push rods 310 are started. The U-shaped frame 320 drives the L-shaped plate 330 to move downward, so that the L-shaped plate 330 pulls the connecting rope 262 to drive the support plate 220 to move upward. The smart push rod 230 is not easy to rotate due to the force of the torsion spring. When the support plate 220 moves upward, the U-shaped frame 210 will not rotate, and the slider 260 is not easy to slide due to the push of the rebound spring 261, so that the middle part of one end of the support plate 220 is forced to move upward, and the support plate 220 is moved upward. The plate 220 only supports the weight of the cylinder that has been cut and dropped onto the support plate 220 without being too heavy. After the top of the support plate 220 is embedded in the U-shaped frame 210, the two electric push rods 310 continue to pull the L-shaped plate 330 downward through the U-shaped frame 320, so that the slider 260 continues to move upward under the tension, thereby resisting the compression rebound spring 261 and moving toward one end of the guide groove 222. The support plate 220 drives the U-shaped frame 210 to deflect as a whole, thereby completing the rotation of the steel ingot, which is convenient for continuing to cut the steel ingot and controlling the thickness of the ring.

[0040] The outer wall of the fixing rod 250 is provided with a limiting groove 251 , and the connecting rope 262 is located inside the limiting groove 251 , so that the limiting groove 251 can limit the position of the connecting rope 262 to prevent the connecting rope 262 from being separated from the fixing rod 250 .

[0041] The two opposite inner walls of the water tank 110 are staggered with roller groups 340, which include an upper roller and a lower roller connected by a transmission belt. Both ends of the four rollers are fixedly connected with a connecting plate 341, and the connecting plate 341 is fixedly connected to the inner wall of the adjacent water tank 110. The two arms of the U-shaped frame 320 are respectively located inside the two transmission belts 350 and are fixedly connected to the inner wall of the transmission belt 350. A filter screen 360 is provided inside the water tank 110 between the two transmission belts 350, and the filter screen 360 is divided into two opposite sides. The U-shaped frame 320 is fixedly connected to the outer side wall of the two transmission belts 350, and the two electric push rods 310 are started to drive the U-shaped frame 320 to move downward, so that the two arms of the U-shaped frame 320 drive the transmission belt 350 to rotate. In the initial position, the U-shaped frame 320 is located above the filter screen 360. After the two transmission belts 350 rotate, the positions of the U-shaped frame 320 and the filter screen 360 are swapped, so that the filter screen 360 is close to the water surface, which is convenient for users to clean up the metal scraps that fall onto the filter screen 360 due to cutting by the cutting machine.

[0042] The resistance mechanism 400 includes a resistance plate 410, one side of which is fixedly connected to a slide plate 420. A sliding opening 112 is opened at one end of the water tank 110, and the slide plate 420 is slidably connected to the inside of the sliding opening 112. The bottom surface of the resistance plate 410 is rotatably connected to a connecting rod 430. One end of the connecting rod 430 is rotatably connected to the bottom end of the L-shaped plate 330, so that when the U-shaped frame 320 drives the L-shaped plate 330 to move downward, the resistance plate 410 will be simultaneously pulled by the connecting rod 430 to move toward the rotating support plate 220, so that the resistance plate 410 and the U-shaped frame 210 clamp the rotated steel ingot, thereby improving the stability of the steel ingot.

[0043] The bottom surface of the abutment plate 410 is rotatably connected to a rotating rod 440, and one end of the rotating rod 440 is rotatably connected to a scraper 441, the scraper 441 contacts the top surface of the filter screen 360, and an outlet 113 is provided at the other end of the water tank 110. The initial state of the rotating rod 440 is a state of not contacting the filter screen 360, so that when the abutment plate 410 is pulled by the L-shaped plate 330 through the connecting rod 430, the filter screen 360 will gradually move upward due to the rotation of the two transmission belts 350, so that the rotating rod 440 is pushed by the abutment plate 410 and the top of the filter screen 360 and tilts and the tilt degree continues to increase, so that the scraper 441 scrapes on the filter screen 360, and the metal scraps produced by cutting on the filter screen 360 are scraped to the outside of the water tank 110 through the outlet 113, so that the metal scraps can be automatically cleaned.

[0044] A frosted layer 411 is provided on the fixed side of the abutment plate 410 , so that the steel ingot is not likely to slip when it contacts the abutment plate 410 during rotation, thereby preventing the steel ingot from slipping off the U-shaped frame 210 .

[0045] Working principle: When in use, place the ingot on the two arms of the U-shaped frame 210, and make part of the ingot located on the two slide bars 232. In the initial position, the support plate 220 naturally lies at the bottom of the four support rods 211 due to its own weight, so that the support plate 220 drives the two rotating plates 240 to rotate vertically and abut against the adjacent abutting strips 241 through the two pulling belts 223. A controller is set on the mounting plate 120 to control the opening and closing of the intelligent push rod 230. Then start the intelligent push rod 230, so that the movable end of the intelligent push rod 230 extends out to drive the fixing plate 231 to press the ingot on the two rotating plates 240 for clamping. Then start the machine body 100, so that the molybdenum wire on the machine body 100 enters the inside of the water tank 110 from the inlet groove 111 to cut the ingot. After cutting out the outer contour of the ring on the ingot, the columnar body cut out in part may slide to the support plate 220 due to gravity at the bottom and be supported by the support plate 220, but its top is still inside the ingot. Then start the machine body 100 to reset the molybdenum wire;

[0046] Then, a controller is set outside the water tank 110 to control the opening and closing of the two electric push rods 310. Start the two electric push rods 310, so that the movable ends of the two electric push rods 310 extend out to push the U-shaped frame 320 to move downward. The U-shaped frame 320 drives the L-shaped plate 330 to move downward synchronously. The L-shaped plate 330 pulls one end of the connecting rope 262, so that the other end of the connecting rope 262 pulls the slider 260 to drive the support plate 220 to move upward. Due to the pushing of the return spring 261, the slider 260 is not easily displaced and drives the support plate 220 to move upward steadily, pushing the cut column back into the ingot. After the top of the support plate 220 is fitted into the inside of the U-shaped frame 210, start the intelligent push rod 230 to reset. At this time, the fixing plate 231 drives the two slide bars 232 to reset, and the two slide bars 232 drag the ingot to move part. Because the support plate 220 moves upward, the two pulling belts 223 are slack. Then the two rotating plates 240 are attached to the top surface of the U-shaped frame 210 due to the reset elastic force of the torsion spring. Start the intelligent push rod 230 again to make the fixing plate 231 abut against the ingot and make the ingot abut against the ends of the two rotating plates 240 for fixation;

[0047] At the same time, the L-shaped plate 330 moves downward and pulls the abutting plate 410 to move toward the support plate 220 through the connecting rod 430. Then continue to start the two electric push rods 310 to make the U-shaped frame 320 continue to move downward. The L-shaped plate 330 continues to pull the slider 260 to move upward through the connecting rope 262. The initial position of the slider 260 is at one end of the guiding groove 222. Under the pulling force of the connecting rope 262, the slider 260 compresses the return spring 261 and drives one side of the support plate 220 to move upward, so that the support plate 220 drives the U-shaped frame 210 and the ingot to rotate synchronously with the intelligent push rod 230 as the axis. At the same time, the L-shaped plate 330 continues to pull the abutting plate 410 to slide toward the support plate 220 through the connecting rod 430 until the support plate 220 completely rotates to the vertical. At this time, the ingot is clamped by the abutting plate 410 and the U-shaped frame 210. Then start the machine body 100 to make the molybdenum wire cut the vertical ingot to cut out the thickness of the ring;

[0048] During the downward movement of the U-shaped frame 320, the U-shaped frame 320 pulls the two transmission belts 350 to rotate, so that the filter screen 360 originally located below the U-shaped frame 320 gradually moves upward with the rotation of the transmission belts 350. When the steel ingot is clamped by the abutment plate 410 and the U-shaped frame 210, the filter screen 360 is located above the water surface and above the U-shaped frame 320. At the same time, the rotating rod 440 is pushed by the abutment plate 410 and the filter screen 360 is pushed upward, so that the scraper 441 scrapes the filter screen 360, and the metal scraps produced by cutting on the filter screen 360 are scraped to the outside of the water tank 110 through the outlet 113.

[0049] After use, the two electric push rods 310 are started to drive the U-shaped frame 320 and the L-shaped plate 330 to reset, and the connecting rope 262 lowers the slider 260. When lowering, the rebound spring 261 continuously resists the slider 260 due to its own elasticity, and the torsion spring reset force on the smart push rod 230 drives the support plate 220, the U-shaped frame 210 and the steel ingot to gradually reset. The steel ingot is not easy to fall or slip off during the rotation process because the bottom is clamped by the smart push rod 230 and the ends of the two rotating plates 240. After the slider 260 is in position, the slider 260 is completely reset, and as the L-shaped plate 330 continues to move upward, the support plate 220 is reset, and the L-shaped plate 330 moves upward and resets, and at the same time, the connecting rod 430 resists the plate 410 and slides in the opposite direction of the support plate 220 to reset. As the U-shaped frame 320 moves upward and resets, the two transmission belts 350 rotate in the opposite direction, driving the filter screen 360 to reset, and the user takes out the cut ring material from the support plate 220 and unloads the steel ingot, and the ring material is subjected to hole drilling and other fine processing to obtain the finished ring product.
