Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting technology, and particularly relates to a wire cutting processing device. Background Art

[0002] Wire cutting is short for wire electrical discharge machining. It uses a moving metal wire (molybdenum wire, copper wire or alloy wire) as the electrode wire. Relying on the pulsed electric spark discharge between the electrode wire and the workpiece, high temperature is generated to melt or vaporize the metal, forming a cutting seam, thereby cutting out parts. When the existing wire cutting processing device cuts a metal plate, a large amount of heat will be generated during the cutting of the metal plate. It is necessary to immerse the whole metal plate in the coolant for cutting. As the cutting progresses, the coolant gradually becomes turbid. And a large amount of coolant is required for the metal plate to be immersed in the coolant, and the coolant is in a static state (that is, the temperature difference of heat conduction is too small, resulting in a decrease in cooling efficiency), making the temperature at the cutting point of the metal plate easy to accumulate. Therefore, a wire cutting processing device is proposed. Content of the Utility Model

[0005] Further, a filter screen is provided inside the collection tank above the input end of the water pump.

[0006] Further, the moving component includes a first threaded rod connected to the front and back sides of the collection tank through a sealed bearing, a differential one is provided at the back end of the first threaded rod and fixed to the outer wall of the collection tank, a first motor is provided at the input end of the differential one and fixed to the outer shell of the differential one, a first slider closely attached to the right inner wall of the collection tank is threadedly connected to the threaded rod one, two parallel sliding rods are integrally connected to the left side of the first slider, a second threaded rod rotatably connected to the first slider is provided between the two sliding rods, a differential two is provided at the top of the first slider, a second motor is provided at the input end of the differential two and fixed to the outer shell of the differential two, the output end of the differential two is connected to the second threaded rod through two bevel gears, and a clamp threadedly connected to the second threaded rod is slidably connected to the sliding rod.

[0008] Further, the middle part of the filter net is concave, and the connection between the edge and the middle of the filter net is transitioned through an inclined surface. Beneficial effects

[0009] When wire-cutting a metal sheet, first fix the metal sheet to the moving component for cutting. The wire-cutting head performs cutting. The coolant in the collection tank is pumped out through the reflux mechanism, and then the coolant is diverted to the periphery of the cutting wire of the wire-cutting head to cool the cutting wire of the wire-cutting head and the cutting point of the metal sheet. The heat at the cutting point of the metal sheet flows along with the coolant, thereby increasing the temperature difference and improving the cooling efficiency. When removing the cut metal sheet, the surface of the metal sheet is dried by the drying mechanism.

[0010] When using the coolant, the water pump pumps the coolant in the collection tank into the inside of the conduit, and the coolant is sent into the inside of the corrugated pipe through the conduit. At this time, the bottom of the corrugated pipe supports on the metal sheet, and the coolant fills the entire corrugated pipe, so that the periphery of the cutting wire of the wire-cutting head can be completely wrapped by the coolant. At the same time, as the coolant is continuously pumped in, the coolant extends out from the gap between the bottom of the corrugated pipe and the metal sheet, and the leaked coolant flows back into the collection tank again. By making the coolant flow, the coolant is cooled while flowing.

[0019] This embodiment provides a wire cutting processing device, including: a machine tool 1, a collection tank 101 is opened at the top of the machine tool 1, a moving assembly 2 is provided at the top edge of the collection tank 101, a column 3 is provided on the back of the machine tool 1, a connecting arm 4 is provided at the top of the column 3, and a wire cutting head 5 located directly above the machine tool 1 is provided at the other end of the connecting arm 4. A servo controller 8 is provided on the front of the machine tool 1, a return mechanism 6 is provided on one side of the collection tank 101, and a drying mechanism 7 is provided on the moving assembly 2;

[0020] During specific implementation, when wire cutting a metal sheet, first fix the metal sheet to the moving assembly 2 for cutting. The wire cutting head 5 performs cutting. The coolant inside the collection tank 101 is pumped out through the return mechanism 6, and then the coolant is guided to the periphery of the cutting wire of the wire cutting head 5 to cool the cutting wire of the wire cutting head 5 and the cutting point of the metal sheet. The heat at the cutting point of the metal sheet flows along with the coolant, thereby increasing the temperature difference and improving the cooling efficiency. When removing the cut metal sheet, the surface of the metal sheet is dried by the drying mechanism 7;

[0021] The machine tool 1, moving assembly 2, column 3, connecting arm 4, wire cutting head 5, and servo controller 8 all adopt existing technologies.

[0022] Further, the return mechanism 6 includes a bellows 601, the bellows 601 is fixed to the periphery of the cutting wire of the wire cutting head 5, a conduit 602 is provided on the outer wall of the bellows 601, a water pump 603 is provided at the bottom end of the conduit 602, and the input end of the water pump 603 is connected to the inside of the collection tank 101;

[0023] In specific implementation, when using the coolant, the water pump 603 pumps the coolant inside the collection tank 101 into the inside of the conduit 602, and sends the coolant into the inside of the corrugated pipe 601 through the conduit 602. At this time, the bottom of the corrugated pipe 601 is supported on the metal sheet, and the coolant fills the entire corrugated pipe 601 at this time, so that the periphery of the cutting wire of the wire cutting head 5 can be completely wrapped by the coolant. At the same time, the coolant is continuously pumped in, so that the coolant extends out from the gap between the bottom of the corrugated pipe 601 and the metal sheet, and the leaked coolant flows back into the inside of the collection tank 101 again. By making the coolant flow, the coolant is cooled while flowing;

[0024] Advantages: It is not necessary to immerse the whole metal sheet in the coolant, and the amount of coolant used can be reduced.

[0025] Furthermore, a filter screen 102 is provided inside the collection tank 101 above the input end of the water pump 603;

[0026] In specific implementation, through the setting of the filter screen 102, the filter screen 102 can filter the debris separated by cutting.

[0027] Furthermore, the moving assembly 2 includes a first threaded rod 201 connected to the front and rear side surfaces of the collection tank 101 through a sealed bearing. One end of the back of the first threaded rod 201 is provided with a first differential 202 fixed to the outer wall of the collection tank 101. The input end of the first differential 202 is provided with a first motor 203 fixed to the outer shell of the first differential 202. A first slider 204 tightly attached to the right inner wall of the collection tank 101 is threadedly connected to the first threaded rod 201. Two parallel sliding rods 205 are integrally connected to the left side of the first slider 204. A second threaded rod 206 rotatably connected to the first slider 204 is provided between the two sliding rods 205. A second differential 207 is provided at the top of the first slider 204. The input end of the second differential 207 is provided with a second motor 208 fixed to the outer shell of the second differential 207. The output end of the second differential 207 is connected to the second threaded rod 206 through two bevel gears. A clamp 209 threadedly connected to the second threaded rod 206 is slidably connected to the sliding rod 205;

[0028] In specific implementation, the metal sheet is fixed by the clamp 209. When the metal sheet moves left and right, the second motor 208 drives, so that the second differential 207 drives the second threaded rod 206 to rotate, and the clamp 209 moves left and right on the sliding rod 205. When moving back and forth, the first motor 203 drives, so that the first differential 202 drives the first threaded rod 201 to rotate, and the first slider 204 moves back and forth on the first threaded rod 201, so that the first slider 204 and the clamp 209 move back and forth as a whole.

[0029] Furthermore, the drying mechanism 7 includes a fixing base 701 fixed to the ends of the two slide bars 205. A ball hole 702 is provided on the top of the fixing base 701. A rotatable connecting ball 703 is provided inside the ball hole 702. A hot air blower 704 is connected to the top of the connecting ball 703 via a straight rod.

[0030] In a specific implementation, during drying, the hot air blower 704 is turned so that the air outlet of the hot air blower 704 is aligned with the cutting area of the metal sheet. When the hot air blower 704 is turned, the connecting ball 703 rotates inside the ball hole 702 by overcoming the friction force.

[0031] Furthermore, the middle portion of the filter 102 is concave, and the connection between the edge and the middle of the filter is transitioned through an inclined surface;

[0032] In a specific implementation, when the debris generated by cutting is filtered, the filtered debris will naturally gather in the middle of the filter screen 102 through the setting of the inclined surface.
