Description

Technical Field

[0001] The present invention relates to the technical field of sheet metal cutting, and particularly to an automatic device for cutting and chamfering the irregular periphery of a sheet. Background Art

[0002] An automatic device for cutting and chamfering is a mechanical device for rounding the irregular corners of a wooden board, enabling the tool to precisely contact the irregular corners of the wooden board and realizing the automatic processing of the complex contour of the sheet through high-precision control, thereby improving the efficiency of automatic processing of the wooden board.

[0003] The patent with the publication number CN218194270U discloses a device for chamfering a wooden board, which is used to solve the technical problem in the background art that the existing technology operators can only chamfer one corner position of the wooden board at a time, resulting in low efficiency. The patent discloses a device for chamfering a wooden board, including a table board. Two collinear and horizontally extending adjustment grooves are opened at the top of the table board. The adjustment grooves are vertically penetrated through the table board. Chamfering components that can slide along the length direction of the adjustment grooves are slidably arranged in both adjustment grooves. A horizontal sliding groove that penetrates the table board up and down is opened at the top of the table board. The length direction of the sliding groove is perpendicular to the length direction of the adjustment groove, which speeds up the processing of the wooden board by workers.

[0004] However, the current devices for chamfering the corners of wooden boards have the following problems: Due to the unevenness of the irregular periphery of the sheet, the tool is prone to severe jitter when cutting the rounded corners on the sheet, which in turn leads to the problem of uneven cutting of the rounded corners on the irregular periphery of the sheet. Therefore, we propose an automatic device for cutting and chamfering the irregular periphery of a sheet. Summary of the Invention

[0016] The present invention adopts the above technical solution, and can bring the following beneficial effects: (1) In the present invention, through the cooperation of a cabinet, a servo electric cylinder, a T-shaped frame, a bottom plate, an electric telescopic rod, a circular tube, a sliding rod, a first spring, a double-hole plate, a T-shaped shaft, a concave circular block and a motor with a cutter, the double-hole plate drives the motor to move downward, the rotating shaft of the motor drives the cutter to move downward, the rotating shaft of the motor drives the cutter to rotate, the blade on the cutter cuts the back side of the plate, the double-hole plate drives the T-shaped shaft to rotate, the T-shaped shaft rotates in the concave circular block, the double-hole plate drives the motor to rotate, the rotating shaft of the motor moves in the arc-shaped sliding groove of the bottom plate, and the rotating cutter driven by the rotating shaft of the motor moves in an arc. Under the elastic force of the first spring, the blade of the cutter stably moves in an arc to cut the irregular periphery of the plate, preventing the irregular periphery of the plate from being uneven and causing the cutting fillet of the irregular periphery of the plate to be uneven.

[0017] (2) In the present invention, through the setting of the pressing plate device, the ring plate, the U-shaped frame and the inclined frame cooperate with the rubber roller. The ring plate drives the inclined frame to move backward, the inclined frame supports the U-shaped frame to move backward, and the U-shaped frame drives the rubber roller to move backward. Under the action of friction, the rubber roller rolls backward on the plate, so that the rubber roller presses the upper part of the plate to limit the plate, preventing the displacement of the plate from causing different arc sizes of the cutting fillets on both sides of the plate.

[0018] (3) In the present invention, through the setting of the pressing plate device, the L-shaped rod, the square plate and the second spring cooperate with the L-shaped plate. The L-shaped rod slides backward in the circular hole of the L-shaped plate, the square plate and the L-shaped plate press the second spring, and the second spring begins to contract. Under the elastic force of the second spring, the shaking during the movement of the U-shaped frame is reduced, and the shaking of the U-shaped frame is not transmitted to the plate, preventing the plate from shaking violently and causing poor cutting fillet effect of the plate.

[0019] (4) In the present invention, through the setting of the dust suction device, the U-shaped plate, the trough shell and the suction pipe cooperate with the ring block. The U-shaped plate drives the trough shell to move backward, the trough shell drives the suction pipe to move backward, the connecting piece on the suction pipe is connected to the hose of the dust suction pump, and the ring block is used to fix the suction pipe. When the cutter cuts the plate, the trough shell moves to absorb the sawdust and dust generated during the cutting of the cutter, preventing the sawdust and dust generated during the cutting of the cutter from spreading and making it difficult to clean the sawdust and dust in the cabinet.

[0020] (5) In the present invention, through the setting of the dust suction device, the U-shaped strip and the shaft plate cooperate with the arc-shaped elastic piece. The trough shell drives the U-shaped strip to move backward, the U-shaped strip drives the shaft plate to move backward, and the shaft plate drives the arc-shaped elastic piece to move backward. Under the elastic force of the arc-shaped elastic piece, the chamfer of the shaft plate scrapes the sawdust on the rubber roller, preventing the sawdust from adhering to the surface of the rubber roller and causing the surface of the rubber roller to be easily aged and damaged.

[0026] Please refer to Figures 1 - 7 , on the basis of the above embodiment, in another embodiment of the present invention, the pressing plate device 14 includes an annular plate 141. The annular plates 141 are respectively fixed on both sides of the outer wall of the circular tube 6. The bottom surface of the annular plate 141 is fixed with a U-shaped frame 142. The inner top end of the U-shaped frame 142 is fixed with an inclined frame 143. One end of the inclined frame 143 away from the U-shaped frame 142 is fixedly connected to the bottom surface of the annular plate 141. The inclined frame 143 is used to support the U-shaped frame 142. A rubber roller 144 is rotatably installed at the bottom of the inner wall of the U-shaped frame 142; While the circular tube 6 moves backward, the circular tube 6 drives the annular plate 141 to move backward. The annular plate 141 drives the U-shaped frame 142 to move backward. The annular plate 141 drives the inclined frame 143 to move backward. The inclined frame 143 supports the U-shaped frame 142 to move backward. The U-shaped frame 142 drives the rubber roller 144 to move backward. Under the action of friction, the rubber roller 144 rolls backward on the plate, so that the rubber roller 144 presses the upper part of the plate, and the rubber roller 144 limits the position of the plate, thereby avoiding the problem that when the chamfering automation equipment cuts the plate, the displacement of the plate causes the chamfer sizes and arcs on both sides of the plate to be different.

[0027] The bottom surface of the inclined frame 143 is respectively penetrated and fixed with an L-shaped rod 145. A square plate 146 is fixed on the outer wall of the L-shaped rod 145.

One end of the second spring 147 away from the square plate 146 is fixedly connected with the front surface of the L-shaped plate 148. The elastic force when the second spring 147 is compressed reduces the vibration amplitude of the U-shaped frame 142; While the ring plate 141 drives the inclined frame 143 to move backward, the inclined frame 143 drives the L-shaped rod 145 to move backward, the L-shaped rod 145 drives the square plate 146 to move backward, the square plate 146 drives the second spring 147 to move backward, and the L-shaped rod 145 slides backward in the round hole of the L-shaped plate 148. The square plate 146 and the L-shaped plate 148 squeeze the second spring 147, and the second spring 147 begins to contract. Under the elastic force of the second spring 147, the shaking during the movement of the U-shaped frame 142 is reduced, so that the shaking of the U-shaped frame 142 will not be transmitted to the plate, thus avoiding the problem that the plate shakes violently during the cutting of the plate by the round-cornering automation equipment, resulting in poor round-corner cutting effect of the plate.

[0028] The dust suction device 15 includes a U-shaped plate 151. The U-shaped plate 151 is fixed on the top surface of the L-shaped rod 145. A groove shell 152 is fixed at the bottom of the outer wall of the U-shaped plate 151. The front sides of the groove shell 152 are respectively penetrated and fixed with a suction pipe 153.

The connector on the suction pipe 153 is connected with the hose of the dust suction pump. The ring block 154 is used to fix the suction pipe 153, so that when the cutter 13 cuts the plate, the groove shell 152 moves to absorb the sawdust and dust generated during the cutting of the cutter 13, thus avoiding the problem that the sawdust and dust generated during the cutting of the cutter 13 during the cutting of the plate by the round-cornering automation equipment are scattered, making it difficult to clean the sawdust and dust in the cabinet 1.

[0029] A U-shaped strip 155 is fixed on the front surface of the groove shell 152. A shaft plate 156 is rotatably installed on the inner wall of the U-shaped strip 155. A chamfer is formed on the front surface of the shaft plate 156. An arc-shaped elastic piece 157 is fixed on the top surface of the shaft plate 156. One side of the arc-shaped elastic piece 157 away from the shaft plate 156 is fixedly connected with the front surface of the groove shell 152. The chamfer of the shaft plate 156 is used to scrape the sawdust on the surface of the rubber roller 144; While the U-shaped plate 151 drives the trough shell 152 to move backward, the trough shell 152 drives the U-shaped strip 155 to move backward, the U-shaped strip 155 drives the shaft plate 156 to move backward, the shaft plate 156 drives the arc-shaped elastic piece 157 to move backward. When the rubber roller 144 rolls, under the elastic force of the arc-shaped elastic piece 157, the chamfer of the shaft plate 156 scrapes the sawdust on the rubber roller 144, thus avoiding the problem that the surface of the rubber roller 144 is easily aged and damaged due to the attachment of sawdust on the surface of the rubber roller 144 when the round-corner automation equipment cuts the board.
