[0002] Wire cutting device is a kind of precision processing equipment that uses a continuously moving thin metal wire (electrode wire) as a tool electrode to erode metal and cut into shape through pulsed spark discharge. It is mainly used to process various complex and precise small workpieces, such as punches, dies, convex and concave dies, fixed plates, unloading plates, etc. of dies, as well as forming tools, templates, etc. Wire cutting technology has the advantages of small processing allowance, high processing accuracy, short production cycle, and low manufacturing cost. It is widely used in mold manufacturing, medical equipment, aerospace and other fields.

[0003] A Chinese patent with announcement number CN 206305562 U discloses a distance-adjustable wire cutting device cutting head mechanism. By adjusting the position of one mounting seat relative to the other mounting seat, the distance between the two guide wheel seats can be adjusted, thereby adjusting the length of the molybdenum wire working part between the guide wheel seats, so that the wire cutting device can freely adjust the length of the molybdenum wire working part according to the height of the workpiece, thereby improving the adaptability of the wire cutting device to workpieces of different sizes.

[0004] In the current existing technology, when cutting semiconductors, a diamond wire cutter is usually used for cutting. When cutting, the cutting performance is more stable when cutting closer to the center position of the diamond wire cutter. When the thickness of the semiconductor sheet is inconsistent, the center position of the semiconductor sheet and the cutting center of the diamond wire cutter will change, resulting in unstable cutting.

[0005] To this end, the present invention provides an adjustable wire cutting device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0008] By measuring the thickness of the sheet material, the adjusting plate assembly in the casing is then adjusted. The adjusting plate assembly drives the L-shaped bars on the four corners of the frame plate to move upward and the rack bar to move downward through the gears. When the two move to a certain position relative to each other, the distance between them is just the thickness of the sheet material. The sheet material is placed into the casing from the placement port on one side of the casing, and the four corners of the sheet material are placed between the four groups of L-shaped bars and the rack bar for fixation. Subsequently, the two release devices energize the wire knife to control the knife shifting mechanism in the knife shifting box to drive the wire knife to move the sheet material, thereby realizing the effect of wire cutting of the sheet material. By adjusting the distance between the L-shaped bar and the rack bar through the adjusting plate assembly, the thickness center of the sheet material and the cutting center position of the wire knife can be on the same horizontal line when the sheet material is placed into the casing, so that when the sheet material is cut, the force on the cutting surfaces of the upper and lower sides of the sheet material is evenly distributed, making the cutting performance more stable.

[0009] Preferably, the adjusting plate assembly includes a motor, and there are two motors. A rotating shaft is fixedly installed at the output ends of the two motors, and a circular rack is fixedly installed at one end of the two rotating shafts. Two gears are fixedly installed at the other ends of the two rotating shafts, respectively. The teeth on the two gears and the circular rack are respectively meshed with the teeth on the four L-shaped bars and the rack rod. When adjusting the torque, the motor drives the rotating shaft to rotate, and when the rotating shaft rotates, it drives the gears and circular racks at both ends to rotate, and the L-shaped bar is driven to move upward and the rack rod is moved downward through the meshing of the teeth, so as to adjust the distance between the two L-shaped bars and the rack rod, thereby realizing the function of adjusting the width, so that the device can be adapted to process plates of different thicknesses.

[0010] The two L-shaped bars are designed to be pivotally connected to the rack and to be moved relative to each other so that the two L-shaped bars can be moved relative to each other.

[0011] Preferably, a push plate is provided inside the frame plate, and a circular opening is symmetrically opened on the inner wall of the push plate, and the center position of the circular opening is on the same horizontal line as the center position of the circular rack, wherein a connecting rod one and a connecting rod two are fixedly installed between the inner sides of the bottom ends of the two L-shaped bars and the rack rod, respectively, and one end of the connecting rod one and the connecting rod two are slidably connected to the inner wall of the push plate respectively. When the adjustment of the L-shaped bar and the rack rod is completed, the push plate is pushed to drive two of the L-shaped bars and the rack rod to move, so that two of the L-shaped bars and the rack rod slide on the frame plate toward the other two groups, and at the same time the circular rack slides in the circular opening to adjust the distance between the four groups of L-shaped bars and the rack rod, so as to adjust the lateral placement distance of the sheet material, and prevent the four groups of L-shaped bars and the rack rod from being unable to fix the sheet material in place when the sheet material is too short.

[0012] Preferably, a rotating cylinder is fixedly installed on the inner wall of one side of the frame plate, and a screw is fixedly installed on the output end of the rotating cylinder, and a shift block is threadedly connected to the outer wall of the screw, and the top of the shift block is fixedly connected to the bottom of the push plate, and a light rod is symmetrically fixedly installed on one side of the frame plate, and the inner wall of the bottom end of the push plate is slidably connected to the outer walls of the two light rods. A guide rail is fixedly installed on the top of the frame plate, and the bottom of the shift block is slidably connected to the inner wall of the guide rail. When the sheet material is too short, the screw is driven to rotate by controlling the rotating cylinder. When the screw rotates, the push plate is driven to move in the guide rail through the shift block. At the same time, the two sides of the bottom end of the push plate slide on the light rod to provide power for the movement of the push plate, thereby enabling the push plate to achieve the effect of lateral adjustment. The setting of the guide rail and the two light rods can provide good stability for the push plate when it moves.

[0013] Preferably, a rectangular plate is fixedly installed at one end of one of the bottom plates, one of the release devices is placed in the middle of the bottom of the rectangular plate, four inner sliding boxes are fixedly installed at the bottom of the rectangular plate, the inner walls of the four inner sliding boxes are fixedly installed with sliding rods, the outer walls of the sliding rods are slidably connected with a stop block, a return spring is arranged between the top of the stop block and the inner wall of the inner sliding box, and the return spring is placed outside the sliding rod. When the sheet is placed, since the initial position of the wire cutter is placed inside the side of the placing plate, when the other two groups of L-shaped bars and the rack bar drive the placing plate to move relatively, one of the placing plates will lift the stop block The block moves upward, so when the knife moving mechanism in the knife moving box is driven to drive the wire knife to perform cutting through the rod, the wire knife moves inward from one side of the placement plate, and when the stop block on the bottom of the rectangular plate slides out from the placement plate, the stop block will slide out of the inner sliding box under the elastic force of the reset spring, and the bottom of the stop block will contact the surface of the sheet material, so that when the wire knife is performing cutting, the four stop blocks will resist the whole body of the cutting surface of the sheet material to prevent the sheet material from shaking or shifting during cutting, causing the cutting to run away, and also provide a certain stability for the wire knife during cutting.

[0014] Preferably, one end of the other belt rod is fixedly installed with a rectangular box, and the other release device is placed in the middle position inside the rectangular box. The top of the rectangular box is slidably connected to a material receiving trough body, and a strip board is fixedly installed on the outer wall of the rectangular box. A sliding shaft is fixedly installed on the bottom of the material receiving trough body, and the outer wall of the sliding shaft is slidably connected to the inner wall of the strip board. A pressure spring is arranged between the bottom of the material receiving trough body and the top of the strip board, and the pressure spring is placed outside the sliding shaft. The bottom of the rectangular box is slidably connected to the top of the frame plate. When one of the placing plates lifts the stop block to move upward, the other placing plate will push the material receiving trough body to squeeze the pressure spring to move on the rectangular box. When the wire knife moves, the material receiving trough body will slide out from the bottom of the other placing plate, and the pressure spring will be reset to fit the bottom of the sheet material under the elastic force of the pressure spring, so that when the wire knife is cutting, the cut material will enter the rectangular box through the material receiving trough body for collection, thereby facilitating collection.

[0015] Preferably, the inner wall of the rectangular box is symmetrically provided with sliding plates, and the outer walls of the two sliding plates are fixedly installed with shifting rods, one end of the two shifting rods is fixedly installed on the bottom of the material receiving trough body, when the material receiving trough body moves on the rectangular box, the material receiving trough body drives the sliding plates to move in the rectangular box through the shifting rods, and when the material receiving trough body is in contact with the lower surface of the sheet material, the two sliding plates are placed under the sheet material in the rectangular box, and the distance between the sliding plates in the material receiving trough body is adjusted by moving the material receiving trough body, so that the sliding plates can be always placed on both sides directly below the cutting point, so that the cut material can be slid into the rectangular box for collection.

[0016] Preferably, the inner wall of the casing is provided with a viewing opening, the outer wall of the casing is provided with a sliding door and a plate door, and a dust extraction device is fixedly installed on the top of the casing. During operation, the plate door can be pulled to place the sheet material in the casing for processing. The viewing opening can enable the device to observe the processing operations in the casing during processing. The sliding door is provided to facilitate entry into the casing for subsequent operations. During processing, the dust extraction device can continuously perform exhaust operations in the casing so that the dust cut by the wire knife during cutting can be extracted, thereby removing harmful dust in the casing and protecting the health of the operators.

[0017] Preferably, a material storage box is fixedly installed on the top of the knife shifting box, and an inclined sliding plate is fixedly installed on one side of the frame plate. The inclined sliding plate is placed inside the material storage box. When the wire knife cutting is completed, the moving mechanism in the knife shifting box drives the wire knife to reset. When the reset is completed, the material placed in the rectangular box will lose the limiting blockage of the frame plate, and the material will slide out from the bottom of the rectangular box to the inclined sliding plate, and finally fall into the material storage box for collection. Then, by pulling the sliding door to open it, the material in the material storage box can be taken out, which is convenient for taking materials.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The adjustable wire cutting device described in the present invention drives the rotating shaft to rotate through a motor, and when the rotating shaft rotates, it drives the gears and round racks at both ends to rotate, and the L-shaped bar is driven to move upward and the rack bar is driven to move downward through the meshing of teeth. The distance between the L-shaped bar and the rack bar can be adjusted so that when the sheet material is placed into the casing, the thickness center of the sheet material is on the same horizontal line as the cutting center position of the wire knife, so that when the sheet material is cut, the force on the cutting surfaces on the upper and lower sides of the sheet material is uniform, making the cutting performance more stable.

[0020] 2. The adjustable wire cutting device described in the present invention drives the screw to rotate by controlling the rotating cylinder. While the screw rotates, the push plate is pushed by the shift block to drive two groups of L-shaped bars and rack bars to move, so that two groups of L-shaped bars and rack bars slide on the frame plate to approach the other two groups, and at the same time, the circular rack slides in the circular mouth to adjust the distance between the four groups of L-shaped bars and the rack bar, so as to adjust the lateral placement distance of the sheet material, and prevent the four groups of L-shaped bars and rack bars from being unable to fix the sheet material when the sheet material is too short.

[0021] 3. The adjustable wire cutting device described in the present invention drives the wire cutter to perform cutting by means of a knife moving mechanism. The wire cutter moves inward from one side of a placing plate. When the stop block on the bottom of the rectangular plate slides out from the placing plate, the stop block slides out of the inner sliding box under the elastic force of the return spring. The bottom of the stop block contacts the surface of the sheet material. When the wire cutter performs cutting, the four stop blocks press against the entire cutting surface of the sheet material to prevent the sheet material from shaking or shifting during cutting, thereby preventing the cutting knife from running away. At the same time, it also provides a certain stability for the wire cutter during cutting.

[0022] 4. The adjustable wire cutting device described in the present invention has the advantages that when the wire knife moves, the material receiving trough will slide out from the bottom of another placing plate, and under the elastic force of the pressure spring, the pressure spring will reset and fit the bottom of the sheet material, so that when the wire knife is moving and cutting, the cut material will enter the rectangular box through the material receiving trough for collection, thereby facilitating collection.

[0023] 5. The adjustable wire cutting device described in the present invention adjusts the distance of the sliding plate in the material receiving trough body by moving the material receiving trough body, so that the sliding plate can be always placed on both sides directly below the cutting position, so that the cut material can be slid into a rectangular box for collection. When the moving mechanism drives the wire cutter to reset, the material placed in the rectangular box will lose the limiting blockage of the frame plate, and the material will slide out from the bottom of the rectangular box to the inclined slide plate, and finally fall into the material box, which is convenient for taking out the material.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 12 As shown, an adjustable wire cutting device according to an embodiment of the present invention comprises a casing 1, a bottom plate 8 is fixedly mounted on the inner wall of the casing 1, a frame plate 15 is fixedly mounted on the top of the bottom plate 8, four corners of the frame plate 15 are slidably connected with L-shaped bars 22 and rack bars 23, an adjusting plate assembly is arranged on the top of the frame plate 15, the adjusting plate assembly comprises a gear 19, two gears 19 are arranged, the gear 19 is used to drive the L-shaped bars 22 and rack bars 23 at the four corners of the frame plate 15 to move up and down, a sheet is arranged between the L-shaped bars 22 and the rack bars 23, a knife shifting box 6 is fixedly mounted on the inner wall of the casing 1, a knife shifting mechanism is arranged inside the knife shifting box 6, belt rods 9 are symmetrically arranged inside the bottom plate 8, one end of the two belt rods 9 are fixedly mounted with release devices 38, a wire cutter 37 is arranged between the two release devices 38, the knife shifting mechanism in the bottom plate 8 drives the wire cutter 37 to move and cut the sheet through the two belt rods 9, and a placement opening is opened on one side inner wall of the casing 1;

[0040] Since the cutting is most stable when the wire knife 37 is cut at the center position, when the thickness of the sheet is inconsistent, the center position of the sheet and the cutting center of the wire knife 37 will change, resulting in unstable cutting;

[0041] By measuring the thickness of the sheet material, the adjusting plate assembly in the casing 1 is then adjusted. The adjusting plate assembly drives the L-shaped bars 22 on the four corners of the frame plate 15 to move upward and the rack bar 23 to move downward through the gear 19. When the two move to a certain position relative to each other, the distance between them is just the thickness of the sheet material. The sheet material is placed into the casing 1 from the placement port on one side of the casing 1, and the four corners of the sheet material are respectively placed between the four groups of L-shaped bars 22 and the rack bar 23 for fixation. Then, the two release devices 38 energize the wire knife 37, control the knife shifting mechanism in the knife shifting box 6 to drive the wire knife 37 to move the sheet material, thereby realizing the function of wire cutting the sheet material. The L-shaped bars 22 and the rack bar 23 are adjusted by the adjusting plate assembly. The distance between the rods 23 allows the thickness center of the plate to be on the same horizontal line with the cutting center position of the wire knife 37 when the plate is placed into the casing 1, so that when the plate is cut, the force on the cutting surfaces of the upper and lower sides of the plate is uniform, making the cutting performance more stable. It should be noted here that the knife shifting mechanism in the knife shifting box 6 is a prior art and is not shown in the drawings of this technical scheme. The initial position of the wire knife 37 is placed on one side of two groups of L-shaped bars 22 and the rack rod 23. The center position of the gap between the four groups of L-shaped bars 22 and the rack rod 23 is initially on the same horizontal line with the cutting center of the wire knife 37. The wire knife 37 is a diamond wire cutting tool and the plate is a semiconductor plate.

[0042] like Figures 4 to 5 As shown, the adjustment plate assembly includes a motor 12, and there are two motors 12. The output ends of the two motors 12 are fixedly mounted with a rotating shaft 16, and one end of the two rotating shafts 16 is fixedly mounted with a round rack 17. Two gears 19 are respectively fixedly mounted on the other ends of the two rotating shafts 16, and the teeth on the two gears 19 and the round rack 17 are respectively meshed with the teeth on the four L-shaped bars 22 and the rack bar 23;

[0043] When adjusting the torque, the motor 12 drives the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it drives the gears 19 and the round rack 17 at both ends to rotate, and drives the L-shaped bar 22 to move upward and the rack bar 23 to move downward through the engagement of the teeth, and adjusts the distance between the two L-shaped bars 22 and the rack bar 23, thereby achieving the function of adjusting the width, so that the device can be adapted to process sheets of different thicknesses. It should be noted here that both the L-shaped bar 22 and the rack bar 23 are provided with teeth that mesh with the rotating shaft 16 and the gear 19.

[0044] like Figures 4 to 5As shown, a second clamping plate 18 and a first clamping plate 14 are fixedly installed between two L-shaped bars 22 and the rack bar 23, and a placement plate 11 is fixedly installed between the other two L-shaped bars 22 and the rack bar 23. A limiting plate 31 is fixedly installed on one side of the second clamping plate 18 and the first clamping plate 14, and the limiting plate 31 is placed in a placement opening opened on the inner wall of one side of the housing 1;

[0045] When the L-shaped bar 22 moves upward and the rack bar 23 moves downward, the two groups of L-shaped bars 22 and the rack bar 23 respectively drive the second clamp 18 and the first clamp 14 to move relative to each other, and at the same time drive the two limit plates 31 to move up and down at the placement opening on one side of the casing 1 to open. When the L-shaped bar 22 and the rack bar 23 are adjusted to the same thickness as the processed sheet, the opening distance of the two limit plates 31 is the thickness of the sheet. The setting of the two limit plates 31 is convenient for placing the sheet and plays a role in receiving the sheet. At the same time, the other two groups of L-shaped bars 22 and the rack bar 23 also drive the placement plate 11 to move relative to each other. The placement plate 11 is set to place the wire cutter 37, so that when the sheet is placed into the casing 1, the wire cutter 37 will not affect the fixation of the sheet by the L-shaped bar 22 and the rack bar 23.

[0046] like Figures 5 to 9 As shown, a push plate 20 is arranged inside the frame plate 15, and a circular opening 28 is symmetrically opened on the inner wall of the push plate 20, and the center position of the circular opening 28 is on the same horizontal line as the center position of the circular rack 17, wherein a connecting rod 1 24 and a connecting rod 25 are respectively fixedly installed between the inner sides of the bottom ends of the two L-shaped bars 22 and the rack bar 23, and one end of the connecting rod 1 24 and the connecting rod 25 are respectively slidably connected to the inner wall of the push plate 20;

[0047] When the adjustment of the L-shaped bars 22 and the rack bars 23 is completed, the push plate 20 is pushed to drive two groups of the L-shaped bars 22 and the rack bars 23 to move, so that two groups of the L-shaped bars 22 and the rack bars 23 slide on the frame plate 15 and approach the other two groups. At the same time, the circular rack 17 slides in the circular mouth 28 to adjust the distance between the four groups of L-shaped bars 22 and the rack bars 23, so as to adjust the lateral placement distance of the sheet material, and prevent the four groups of L-shaped bars 22 and the rack bars 23 from being unable to fix the sheet material in place when the sheet material is too short.

[0048] like Figures 7 and 8 As shown, a rotary cylinder 26 is fixedly installed on the inner wall of one side of the frame plate 15, a screw rod 21 is fixedly installed on the output end of the rotary cylinder 26, a displacement block 30 is threadedly connected to the outer wall of the screw rod 21, the top of the displacement block 30 is fixedly connected to the bottom of the push plate 20, a polished rod 27 is symmetrically fixedly installed on one side of the frame plate 15, the inner wall of the bottom end of the push plate 20 is slidably connected to the outer walls of the two polished rods 27, a guide rail 29 is fixedly installed on the top of the frame plate 15, and the bottom of the displacement block 30 is slidably connected to the inner wall of the guide rail 29;

[0049] When the sheet is too short, the screw 21 is driven to rotate by controlling the rotating cylinder 26. While the screw 21 rotates, the push plate 20 is driven to move in the guide rail 29 through the shift block 30. At the same time, the bottom ends of the push plate 20 slide on the light rods 27 to provide power for the movement of the push plate 20, thereby enabling the push plate 20 to be adjusted laterally. The setting of the guide rail 29 and the two light rods 27 can provide good stability for the push plate 20 when it moves.

[0050] like Figure 10 to Figure 11 As shown, a rectangular plate 10 is fixedly mounted on one end of one of the bottom plates 8, a discharge device 38 is placed at the middle position of the bottom of the rectangular plate 10, four inner slide boxes 33 are fixedly mounted on the bottom of the rectangular plate 10, and slide bars 36 are fixedly mounted on the inner walls of the four inner slide boxes 33. A stop block 34 is slidably connected to the outer wall of the slide bar 36. A return spring 35 is arranged between the top of the stop block 34 and the inner wall of the inner slide box 33, and the return spring 35 is placed outside the slide bar 36.

[0051] When the sheet is placed, since the initial position of the wire cutter 37 is placed on the inner side of the placing plate 11, when the other two groups of L-shaped bars 22 and the rack bar 23 drive the placing plate 11 to move relatively, one of the placing plates 11 will lift the stopper 34 to move upward. Therefore, when the knife shifting mechanism in the driving knife shifting box 6 drives the wire cutter 37 to perform knife cutting through the belt rod 9, the wire cutter 37 moves inward from one side of the placing plate 11. When the stopper 34 on the bottom of the rectangular plate 10 slides out from the placing plate 11, the stopper 34 will slide from the inside under the elastic force of the reset spring 35. When the wire cutter 37 is in the process of cutting, the four stop blocks 34 will press against the cutting surface of the sheet material to prevent the sheet material from shaking or shifting during cutting, thereby preventing the cutting from running away. At the same time, it also provides a certain stability for the wire cutter 37 during cutting. It should be noted that the initial position of the stop block 34 should be placed on one of the placement plates 11, and a rubber slide is provided at the bottom of the stop block 34 to prevent the elastic force of the return spring 35 from being too large to damage the surface of the sheet material.

[0052] like Figures 10 to 12 As shown, a rectangular box 32 is fixedly installed at one end of another belt rod 9, another discharger 38 is placed in the middle position inside the rectangular box 32, a material receiving trough 40 is slidably connected to the top of the rectangular box 32, a strip plate 44 is fixedly installed on the outer wall of the rectangular box 32, a sliding shaft 41 is fixedly installed on the bottom of the material receiving trough 40, the outer wall of the sliding shaft 41 is slidably connected to the inner wall of the strip plate 44, a pressure spring 42 is arranged between the bottom of the material receiving trough 40 and the top of the strip plate 44, the pressure spring 42 is placed outside the sliding shaft 41, and the bottom of the rectangular box 32 is slidably connected to the top of the frame plate 15;

[0053] When one of the placing plates 11 lifts the stop block 34 to move upward, the other placing plate 11 will push the material receiving trough body 40 to squeeze the pressure spring 42 to move on the rectangular box 32. When the wire knife 37 moves in a cutting motion, the material receiving trough body 40 will slide out from the bottom of the other placing plate 11. Under the elastic force of the pressure spring 42, the pressure spring 42 will reset and fit the bottom of the sheet material, so that when the wire knife 37 is cutting in a cutting motion, the cut material will pass through the material receiving trough body 40 into the rectangular box 32 for collection, thereby facilitating collection. It should be noted here that the initial position of the material receiving trough body 40 should be placed at the bottom of the other placing plate 11, and a rubber slide is provided on the top of the material receiving trough body 40 to prevent the elastic force of the pressure spring 42 from being too large to damage the sheet material.

[0054] like Figures 10 to 12 As shown, the inner wall of the rectangular box 32 is symmetrically provided with sliding plates 39, and the outer walls of the two sliding plates 39 are fixedly installed with shifting plate rods 43, and one end of the two shifting plate rods 43 is fixedly installed at the bottom of the receiving trough body 40;

[0055] When the material receiving trough body 40 moves on the rectangular box 32, the material receiving trough body 40 drives the sliding plate 39 to move in the rectangular box 32 through the plate shifting rod 43. When the material receiving trough body 40 is in contact with the lower surface of the sheet material, the two sliding plates 39 are placed under the sheet material in the rectangular box 32. The distance between the sliding plates 39 in the material receiving trough body 40 is adjusted by the movement of the material receiving trough body 40, so that the sliding plates 39 can be always placed on both sides directly below the cutting point, so that the cut material can be slid into the rectangular box 32 for collection. It should be noted here that the sliding plates 39 are placed on both sides of the wire knife 37, and the inclination angles of the two sliding plates 39 need to be actually measured. The gap between the bottom end of the sliding plate 39 and the rectangular box 32 should be larger than the specification size of the workpiece.

[0056] like Figure 1 to Figure 2 As shown, the inner wall of the casing 1 is provided with a viewing opening 4, the outer wall of the casing 1 is provided with a sliding door 3 and a panel door 5, and a dust extraction device 2 is fixedly installed on the top of the casing 1;

[0057] During operation, the sheet material can be placed in the casing 1 for processing by pulling the panel door 5. The viewing port 4 can be used to observe the processing operations in the casing 1 during processing. The sliding door 3 is provided to facilitate entry into the casing 1 for subsequent operations. During processing, the dust extraction device 2 can continuously perform air extraction operations in the casing 1, so that the dust cut out by the wire knife 37 during cutting can be extracted, thereby removing harmful dust in the casing 1 and protecting the health of the operators.

[0058] like Figures 1 to 4 As shown, a material box 7 is fixedly installed on the top of the tool shifting box 6, and an inclined slide 13 is fixedly installed on one side of the frame plate 15, and the inclined slide 13 is placed inside the material box 7;

[0059] When the wire knife 37 completes cutting, the moving mechanism in the knife box 6 drives the wire knife 37 to reset. When the reset is completed, the material placed in the rectangular box 32 will lose the limit blockage of the shelf 15, and the material will slide out from the bottom of the rectangular box 32 to the inclined slide 13, and finally fall into the material box 7 for collection. Then, by pulling the sliding door 3 to open it, the material in the material box 7 can be taken out, which is convenient for taking out materials.

[0060] Working principle: by measuring the thickness of the sheet material, and then adjusting the adjusting plate assembly in the casing 1, the adjusting plate assembly drives the L-shaped bars 22 on the four corners of the frame plate 15 to move upward and the rack bar 23 to move downward through the gear 19. When the two move to a certain position relative to each other, the distance between the two is just the thickness of the sheet material. The sheet material is placed into the casing 1 from the placement port on one side of the casing 1, and the four corners of the sheet material are placed between the four groups of L-shaped bars 22 and the rack bar 23 for fixation. Then, the two release devices 38 energize the wire knife 37, and control the knife shifting mechanism in the knife shifting box 6 to drive the wire knife 37 to move the sheet material, thereby realizing the function of wire cutting the sheet material. By adjusting the distance between the L-shaped bars 22 and the rack bar 23 through the adjusting plate assembly, when the sheet material is placed into the casing 1, the thickness center of the sheet material and the cutting center position of the wire knife 37 are on the same horizontal line, so that when the sheet material is cut, the force on the cutting surfaces of the upper and lower sides of the sheet material is uniform, making the cutting performance more stable.

[0061] When adjusting the torque, the motor 12 drives the rotating shaft 16 to rotate, and when the rotating shaft 16 rotates, the gears 19 and the round rack 17 at both ends are driven to rotate, and the L-shaped bar 22 is driven to move upward and the rack bar 23 is driven to move downward through the meshing of the teeth, and the distance between the two L-shaped bars 22 and the rack bar 23 is adjusted, thereby achieving the function of adjusting the width, so that the device can be adapted to process sheets of different thicknesses;

[0062] When the L-shaped bar 22 moves upward and the rack bar 23 moves downward, the two groups of L-shaped bars 22 and the rack bar 23 respectively drive the second clamping plate 18 and the first clamping plate 14 to move relative to each other, and at the same time drive the two limit plates 31 to move up and down at the placement opening on one side of the casing 1 to open. When the L-shaped bar 22 and the rack bar 23 are adjusted to the same thickness as the processed sheet, the opening distance of the two limit plates 31 is the thickness of the sheet. The setting of the two limit plates 31 is convenient for placing the sheet and plays a role in receiving the sheet. At the same time, the other two groups of L-shaped bars 22 and the rack bar 23 also drive the placement plate 11 to move relative to each other. The placement plate 11 is set to place the wire cutter 37, so that when the sheet is placed into the casing 1, the wire cutter 37 will not affect the fixation of the sheet by the L-shaped bar 22 and the rack bar 23;

[0063] When the adjustment of the L-shaped bar 22 and the rack bar 23 is completed, the push plate 20 is pushed to drive two groups of the L-shaped bar 22 and the rack bar 23 to move, so that the two groups of the L-shaped bar 22 and the rack bar 23 slide on the frame plate 15 and approach the other two groups. At the same time, the round rack 17 slides in the round mouth 28 to adjust the distance between the four groups of L-shaped bar 22 and the rack bar 23, so as to adjust the lateral placement distance of the sheet material, and prevent the four groups of L-shaped bar 22 and the rack bar 23 from being unable to fix the sheet material when the sheet material is too short;

[0064] When the sheet is too short, the screw 21 is driven to rotate by controlling the rotating cylinder 26. The screw 21 drives the push plate 20 to move in the guide rail 29 through the shift block 30 while the bottom of the push plate 20 slides on the polished rod 27 to provide power for the movement of the push plate 20, so that the push plate 20 can be adjusted laterally. The setting of the guide rail 29 and the two polished rods 27 can provide good stability for the push plate 20 when it moves.

[0065] When the sheet is placed, since the initial position of the wire knife 37 is placed on the side of the placing plate 11, when the other two groups of L-shaped bars 22 and the rack bar 23 drive the placing plate 11 to move relatively, one of the placing plates 11 will lift the stop block 34 to move upward. Therefore, when the knife moving mechanism in the driving knife moving box 6 drives the wire knife 37 to move through the belt rod 9 for cutting, the wire knife 37 moves inward from one side of the placing plate 11. When the stop block 34 on the bottom of the rectangular plate 10 slides out of the placing plate 11, the stop block 34 will slide out of the inner sliding box 33 under the elastic force of the return spring 35, and the bottom of the stop block 34 will contact the surface of the sheet, so that when the wire knife 37 is cutting, the four stop blocks 34 will resist the whole body of the cutting surface of the sheet, preventing the sheet from shaking or shifting during cutting, causing the cutting knife to run away, and also providing a certain stability for the wire knife 37 during cutting.

[0066] When one of the placing plates 11 lifts the stop block 34 to move upward, the other placing plate 11 pushes the material receiving trough 40 to squeeze the pressure spring 42 to move on the rectangular box 32. When the wire cutter 37 moves, the material receiving trough 40 slides out from the bottom of the other placing plate 11. Under the elastic force of the pressure spring 42, the pressure spring 42 is reset to fit the bottom of the sheet material, so that when the wire cutter 37 is cutting, the cut material will pass through the material receiving trough 40 into the rectangular box 32 for collection, which facilitates collection.

[0067] When the material receiving trough 40 moves on the rectangular box 32, the material receiving trough 40 drives the sliding plate 39 to move in the rectangular box 32 through the plate shifting rod 43. When the material receiving trough 40 is attached to the lower surface of the sheet material, the two sliding plates 39 are placed under the sheet material in the rectangular box 32. The distance between the sliding plates 39 in the material receiving trough 40 is adjusted by the movement of the material receiving trough 40, so that the sliding plates 39 can be placed on both sides directly below the cutting position, so that the cut material can be slid into the rectangular box 32 for collection.

[0068] During operation, the sheet material can be placed in the casing 1 for processing by pulling the sheet door 5. The viewing port 4 allows the device to watch the processing operation in the casing 1 during processing. The sliding door 3 is provided to facilitate entry into the casing 1 for subsequent operations. During processing, the dust extraction device 2 can continuously perform air extraction operations in the casing 1, so that the gas dust cut by the wire cutter 37 during cutting can be extracted, and harmful gas dust in the casing 1 can be removed to protect the health of the operators.

[0069] When the wire knife 37 completes cutting, the moving mechanism in the knife box 6 drives the wire knife 37 to reset. When the reset is completed, the material placed in the rectangular box 32 will lose the limit blockage of the shelf 15, and the material will slide out from the bottom of the rectangular box 32 to the inclined slide 13, and finally fall into the material box 7 for collection. Then, by pulling the sliding door 3 to open it, the material in the material box 7 can be taken out, which is convenient for taking out materials.
