Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a CNC fabric cutting machine. Background Technology

[0002] In furniture manufacturing, fabrics are mostly cut into specified shapes using cutting machines. However, existing CNC cutting machines can only cut flat surfaces. With the rise of customized furniture, many customers provide furniture drawings of irregularly shaped boards for customization. However, existing CNC cutting machines can hardly meet the processing needs of existing irregularly shaped boards. Moreover, existing cutting methods all use serrations, resulting in wide cuts and reduced board utilization. Therefore, a CNC fabric cutting machine is proposed. Summary of the Invention

[0003] To address at least one of the aforementioned technical shortcomings, this invention provides a CNC fabric cutting machine, comprising a machine table, an air supply system, and a CNC controller. The CNC controller is fixed to one side of the front of the machine table. The bottom of the machine table is provided with four support legs.

Both sides of the turntables are arc-shaped, and both ends are arc-shaped with the arc diameter at both ends being smaller at the top and larger at the bottom. The inner side of the lower arc of the tadpole block is provided with a concave arc-shaped groove. A downwardly inclined control rod is provided in the middle of the rotating rod. The rotating rod is coaxial with the outer arc surface of the tadpole block.

[0007] Furthermore, the horizontal motion component includes two parallel guide rods fixed between the tops of the two support plates. Each guide rod has a slidable sliding block. A high-precision threaded rod is connected to the middle of each sliding block via a threaded hole. Both ends of the high-precision threaded rod are rotatably connected to the tops of the support plates. One end of the high-precision threaded rod is equipped with a differential four. The output end of the differential four is fixedly connected to the threaded rod. The input end of the differential four is connected to a forward / reverse motor four. The housing of the differential four is fixedly connected to the support plates, and the housing of the forward / reverse motor four is fixedly connected to the housing of the differential four.

[0008] Furthermore, the vertical moving component includes an air supply system fixed to the top of the sliding block, and two cylinders fixed to the bottom of the sliding block. The cylinders are internally sealed and connected with telescopic rods that can extend and retract vertically. The air supply system supplies air to the cylinders.

[0009] Furthermore, the cutting assembly includes a transmission cylinder fixed to the bottom of two telescopic rods. Inside the transmission cylinder is a transmission rod, the two ends of which are connected to the shaft holes at both ends of the transmission cylinder. The transmission rod has two helical gears facing the same direction. One end of the transmission cylinder is equipped with a differential six. A forward / reverse motor six is ​​mounted on the housing of the differential six. The output end of the forward / reverse motor six is ​​connected to the input end of the differential six. The output end of the differential six is ​​fixedly connected to the transmission rod. The housing of the differential six is ​​fixedly connected to the transmission cylinder. At the bottom of the transmission cylinder are two vertically downward-facing connecting cylinders. Inside each connecting cylinder is a double-gear rotatably connected. The shaft of the double-gear is connected to the connecting... The cylinder is rotatably connected, and the top of the connecting cylinder is driven by a helical gear meshing with another helical gear. The outer wall of the double gear has two rings of parallel teeth. The bottom of the connecting cylinder is also rotatably connected to two single gears. The two single gears are symmetrically arranged and are respectively connected to the two rings of parallel teeth of the double gear. There is an arc-shaped groove between the outer wall of the single gear and the outer wall of the double gear. There is a taut cutting wire between the two double gears. The cutting wire is limited to parallel positions by four single gears. Both ends of the cutting wire are round and fit on the arc in the middle of the outer wall of the double gear.

[0010] Furthermore, the cutting wire comprises 6 medium steel wires woven from 36 fine steel wires of 0.05mm each.

[0011] Furthermore, the support plate is set in the form of a right-angled trapezoid, and the side of the support plate near the front is an inclined surface.

[0012] Furthermore, the length of the cutting wire is greater than twice the width of the equipment table.

[0013] Beneficial effects:

[0014] 1. During the cutting process, the sheet material is fixed to the machine table by the clamping assembly. The horizontal and vertical moving components are controlled by the control program written by the CNC controller, and the sheet material is cut by the cutting assembly.

[0015] 2. When clamping ordinary sheet metal, turn the handwheel to drive the threaded rod to rotate, so that the threaded rod engages with the threaded hole in the middle of the fixing block, pushing the clamping block to move, so that the two clamping blocks clamp together in the middle, clamping the sheet metal from both ends.

[0016] 3. When fixing irregularly shaped sheets, first wet the surface of the sheet to be fixed with water, place the fixing surface flat in the middle of the upper surface of the equipment table, so that the fixing surface contacts the suction cup, and rotate the control mechanism upward to make the control mechanism drive the connecting plate to move downward, causing several suction cup pistons to move downward, reducing the air pressure inside the suction cup, and fixing the irregularly shaped sheet to the surface of the equipment table under the action of atmospheric pressure.

[0017] 4. When the cutting assembly moves horizontally, the forward and reverse motor four rotates forward, causing the high-precision threaded rod to rotate forward, and the sliding block, vertical moving assembly, and cutting assembly move to the left as a whole. When the forward and reverse motor four rotates in reverse, the high-precision threaded rod rotates in reverse, and the sliding block, vertical moving assembly, and cutting assembly move to the right as a whole. When the cutting assembly moves vertically, the air supply system supplies air to the cylinder, thereby controlling the extension and retraction of the cylinder. When the cylinder's extension rod retracts, air is supplied from the air hole at the bottom of the cylinder; when the cylinder's extension rod extends, air is supplied from the air hole at the top of the cylinder. The extension and retraction length of the extension rod is controlled by controlling the amount of air supplied by the air supply system.

[0018] 5. Compared with the prior art, the present invention can perform fixed cutting of ordinary boards and irregular boards, and cut curved surfaces from irregular or ordinary boards. When cutting curved surfaces, the horizontal motion component and the vertical movement component work simultaneously to make the cutting surface cut by the cutting wire curved. When the horizontal motion component or the vertical movement component works alone, the cutting surface cut by the cutting wire is horizontal or vertical, and a narrower cutting kerf can be cut.

[0019] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0036] Please refer to Figures 1 to 15 ;

[0037] This embodiment provides a CNC fabric cutting machine, see reference. Figure 1 The equipment includes a worktable 1, an air supply system 501, and a CNC controller 7. The CNC controller 7 is fixed to one side of the front of the worktable 1. The bottom of the worktable 1 is provided with four support feet 101. The worktable 1 is provided with a clamping assembly 2 for fixing raw materials. Both ends of the worktable 1 are provided with vertically upward support plates 3. A horizontal moving assembly 4 is provided between the tops of the two support plates 3. A vertically downward moving assembly 5 is provided at the bottom of the horizontal moving assembly 4. A cutting assembly 6 for cutting is provided at the bottom of the vertical moving assembly 5. The air supply system 501 is used to control the vertical extension and retraction of the vertical moving assembly 5.

[0038] In practice, during the cutting process, the sheet material is fixed to the machine table 1 by the clamping assembly 2, and the horizontal moving assembly 4 and the vertical moving assembly 5 are numerically controlled by the control program written by the CNC controller 7. The sheet material is then cut by the cutting assembly 6.

[0039] Further reference Figure 1 and Figure 5 The clamping assembly 2 consists of a fixed block 201, a limiting rod 202, a clamping block 203, a threaded rod 204, and a handwheel 205. The fixed block 201 is fixed to the middle of the upper surface at both ends of the equipment table 1. The fixed block 201 is connected to two parallel limiting rods 202 through two through holes. One end of the inner side of the two limiting rods 202 is connected to the same clamping block 203. The outer middle of the clamping block 203 is provided with a threaded rod 204 through a rotatable connection. The thread of the threaded rod 204 meshes with the threaded hole in the middle of the fixed block 201. One end of the outer side of the threaded rod 204 is provided with a handwheel 205.

[0040] In specific implementation, refer to Figure 1 and Figure 5 When clamping ordinary sheet metal, the handwheel 205 is turned to drive the threaded rod 204 to rotate, so that the threaded rod 204 engages with the threaded hole in the middle of the fixing block 201, pushing the clamping block 203 to move, so that the two clamping blocks 203 clamp together in the middle, clamping the sheet metal from both ends.

[0041] Further reference Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The clamping assembly 2 consists of a suction cup 206, a suction cup piston 207, a connecting plate 208, a push rod 281, and a control mechanism 209. Several suction cups 206 are arranged in a row in the middle of the upper surface of the equipment table 1. The middle of each suction cup 206 penetrates the equipment table 1. A suction cup piston 207 that can move up and down is sealed and connected in the middle of the suction cup 206. The bottom of several suction cup pistons 207 is connected to the same connecting plate 208. Push rods 281 are provided in the middle of both ends of the connecting plate 208. A control mechanism 209 for controlling the up and down movement of the connecting plate 208 is provided in the middle of the lower surface of the equipment table 1.

[0042] In specific implementation, refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 When fixing irregularly shaped plates, first wet the surface of the plate to be fixed with water, then place the fixed surface flat in the middle of the upper surface of the equipment table 1, so that the fixed surface contacts the suction cup 206. By rotating the control mechanism 209 upward, the control mechanism 209 drives the connecting plate 209 downward, causing several suction cup pistons 207 to move downward, reducing the air pressure inside the suction cup 206. Under the action of atmospheric pressure, the irregularly shaped plate is fixed to the surface of the equipment table 1.

[0043] Preferred, Reference Figures 7 to 10The control mechanism 209 includes a fixed plate 291, a turntable 292, a tadpole block 293, an arc-shaped groove 294, a rotating rod 295, and a control rod 296. Two fixed plates 291 are fixedly connected to the upper surface of the equipment platform 1. Turntables 292 are rotatably connected to the inner sides of both fixed plates 291. A rotating rod 295 is located between the two turntables 292, and the rotating rod 295 is integrally connected to the turntables 292. Both ends of the rotating rod 295 extend beyond the turntables 292. The two ends of 295 are connected to the fixed rod 291 through a hole-shaft fit. The inner surface edge of the turntable 292 is provided with tadpole blocks 293. Both sides of the turntable 292 are arc-shaped, and both ends are arc-shaped. The arc diameter at both ends is smaller at the top and larger at the bottom. The inner side of the lower arc of the tadpole block 293 is provided with a concave arc groove 294. The middle of the rotating rod 295 is provided with a downward-sloping control rod 296. The rotating rod 295 is coaxial with the outer arc surface of the tadpole block 293.

[0044] In specific implementation, when the rotation control mechanism 209 is rotated, the control rod 296 is rotated upward, causing the tadpole block 293 to rotate upward. While the tadpole block 293 moves upward, it presses the push rod 281 downward. Driven by the push rod 281, the connecting plate 208 drives several suction cup pistons 207 to move upward, creating a negative pressure inside the suction cup 206, which fixes the irregular plate material by atmospheric pressure.

[0045] Further reference Figure 3 and Figure 4 The horizontal motion component 4 includes two parallel light rods 401 fixed between the tops of the two support plates 3. The two light rods 401 are provided with sliding blocks 402. A high-precision threaded rod 403 is connected to the middle of the sliding block 402 through a threaded hole. The two ends of the high-precision threaded rod 403 are respectively rotatably connected to the top of the support plate 3. A differential 404 is provided at one end of the high-precision threaded rod 403. The output end of the differential 404 is fixedly connected to the threaded rod 403. The input end of the differential 404 is connected to a forward and reverse motor 405. The housing of the differential 404 is fixedly connected to the support plate 3. The housing of the forward and reverse motor 405 is fixedly connected to the housing of the differential 404.

[0046] In specific implementation, when the cutting component 6 moves horizontally, the forward and reverse motor 405 rotates forward, causing the high-precision threaded rod 403 to rotate forward, and the sliding block 402, the vertical moving component 5 and the cutting component 6 move to the left as a whole. When the forward and reverse motor 405 rotates in reverse, the high-precision threaded rod 403 rotates in reverse, and the sliding block 402, the vertical moving component 5 and the cutting component 6 move to the right as a whole.

[0047] The high-precision threaded rod 403 and the threaded hole connected to the high-precision threaded rod 403 are both manufactured by high-precision equipment, namely a high-precision lathe.

[0048] Further reference Figure 4 The vertical moving component 5 includes an air supply system 501 fixed to the top of the sliding block 402, and two cylinders 502 fixed to the bottom of the sliding block 402. The cylinders 502 are internally sealed and connected with telescopic rods 503 that can extend and retract vertically. The air supply system 501 supplies air to the cylinders 502.

[0049] In practice, when the cutting component 6 moves vertically, the air supply system 501 supplies air to the cylinder 502, thereby controlling the extension and retraction of the cylinder 502.

[0050] When the telescopic rod 503 of cylinder 502 retracts, air is supplied from the bottom air port of cylinder 502; when the telescopic rod 503 of cylinder 502 extends, air is supplied from the top air port of cylinder 502.

[0051] The extension length of the telescopic rod 503 is controlled by controlling the inflation volume of the air supply system 501.

[0052] Further reference Figures 12 to 14 The cutting assembly 6 includes a transmission cylinder 601 fixed to the bottom of two telescopic rods 503. Inside the transmission cylinder 601 is a transmission rod 602. Both ends of the transmission rod 602 are connected to the shaft holes at both ends of the transmission cylinder 601. The transmission rod 602 has two helical gears 621 facing the same direction. One end of the transmission cylinder 601 has a differential 603. The housing of the differential 603 has a forward / reverse motor 604. The output end of the forward / reverse motor 604 is connected to the input end of the differential 603. The output end of the differential 603 is fixedly connected to the transmission rod 602. The housing of the differential 603 is fixedly connected to the transmission cylinder 601. The bottom of the transmission cylinder 601 has two vertically downward-facing connecting cylinders 605. Inside each connecting cylinder 605 is a double gear 607 rotatably connected. Shaft 606 of 7 is rotatably connected to connecting cylinder 605. The top of connecting cylinder 605 is driven by meshing helical gear and helical gear 621. The outer wall of double gear 607 is provided with two rings of parallel teeth. The bottom of connecting cylinder 605 is also rotatably connected to two single gears 608. The two single gears 608 are symmetrically arranged and are respectively connected to the two rings of parallel teeth of double gear 607. The outer wall of single gear 608 and the outer wall of double gear 607 are provided with an arc-shaped groove. A taut cutting wire 609 is provided between the two double gears 607. The cutting wire 609 is limited to parallel by four single gears 608. Both ends of the cutting wire 609 are round and fit on the arc in the middle of the outer wall of double gear 607.

[0053] In practical implementation, during cutting, the forward and reverse motor 604 rotates periodically in both directions, causing the differential 603 to rotate periodically in both directions, which in turn drives the transmission rod 602 to rotate periodically in both directions. Through the helical gears 621, the two double gears 607 rotate periodically at the same frequency. At the same time, the double gears 607 mesh with two single gears 608 to rotate at the same frequency, causing the cutting wire 609 to rotate periodically under the action of friction between the double gears 607 and the single gears 608. This causes the parallel end of the cutting wire 609 to be pulled to saw and cut the plate.

[0054] The cutting wire 609 is taut, so that during cutting, the parallel section of the cutting wire 609 can always be perpendicular to the direction of movement of the cutting assembly 6.

[0055] Furthermore, the cutting wire 609 comprises 6 medium steel wires woven from 36 fine steel wires of 0.05mm each;

[0056] In practical implementation, after the cutting wire 609 is woven, the ridges and depressions formed between adjacent thin wires constitute the primary cutting edge for cutting, and the ridges and depressions formed between adjacent medium wires constitute the secondary cutting edge for cutting. When the cutting wire 609 reciprocates, the gap between the board is sawn and cut through the primary and secondary cutting edges, making the cut kerf smaller, only 1.8mm, thus improving the utilization rate of the board.

[0057] Further reference Figure 5 The support plate 3 is set in the form of a right-angled trapezoid, and the side of the support plate 3 near the front is an inclined surface;

[0058] In practice, while ensuring that the support plate 3 has sufficient support, the illumination rate on the equipment table 1 is increased by reducing the volume of the support plate 3.

[0059] Furthermore, the length of the cutting wire 609 is greater than twice the width of the equipment table 1;

[0060] In practice, the length of the 609 cutting wire after tension is greater than the width of the equipment table 1.

[0061] When cutting curved surfaces, the horizontal motion component 4 and the vertical movement component 5 work simultaneously to make the cutting surface cut by the cutting wire 609 curved. When the horizontal motion component 4 or the vertical movement component 5 works alone, the cutting surface cut by the cutting wire 609 is either horizontal or vertical.

[0062] Because the drawing software keeps freezing when drawing threads, the threaded rod in the attached diagram does not have a thread.

[0063] The air supply system 501, CNC controller 7, cylinder, differential, and forward / reverse motor all adopt existing technologies, and their specific principles will not be elaborated here.
