Description

Technical Field

[0001] The present invention relates to the technical field of wood turning, and particularly to a sheet material cutting device with a CAD comparison and calibration function. Background Art

[0002] Cutting wood boards means that after the factory imports logs, the logs are first cut, planed, and straightened according to requirements to make various specifications of wood boards, removing a large amount of impurities and irregular shapes. After pre-processing, they are then sold to customers;

[0004] When cutting and processing wood in cold northern regions, as the temperature drops, the moisture in the wood cell walls begins to freeze, causing the wood volume to shrink and the density to increase. This shrinkage may cause changes in the wood dimensions, thus affecting the cutting accuracy. And when exposed to low temperatures for a long time, the low temperature reduces the toughness of the wood, making it relatively brittle and easily affected by impact and vibration. Therefore, during the cutting process, this brittleness may cause the wood to be more prone to cracks and fractures, which will also increase the difficulty and error of cutting.

[0017] The present invention provides a plate cutting device with CAD comparison and calibration function. It has the following beneficial effects:

[0018] 1. The present invention sets a focused irradiation mechanism so that the heat radiation can be concentrated to preheat the position to be cut. By heating, the shrinkage and deformation of the wood during the cutting process can be slowed down, thereby improving the accuracy and stability of cutting. In addition, heating may reduce the hardness of the wood, making it softer and easier to cut, which helps to improve cutting efficiency, reduce tool wear, and avoid the problem of accuracy loss under the reference CAD comparison and calibration.

[0019] 2. The present invention sets a focusing irradiation mechanism. As the high-precision cutting head descends, the opening and closing plate will continuously rotate under the hinged rotation of the rotating rod, and keep the infrared heat radiation lamp always facing the processing position of the high-precision cutting head to complete the heating work for the area. When the position is changed by continuous lifting and cutting, the heat radiation will not lose a lot of heat energy due to the wrong irradiation position during the frequent lifting and lowering process due to the fixed angle, resulting in poor heating effect and unstable heating effect.

[0020] 3. The present invention sets a focusing irradiation mechanism. When the heating efficiency of heat radiation is not enough to heat up the wooden board in the area around the high-precision cutting head, the heat absorbed by the connecting plate is quickly released to the wooden board through contact with the wooden board, thereby completing the heating effect of the wooden board with a lower temperature, and achieving as much as possible the stable heating effect on the wooden board under various working conditions, thereby further avoiding the adverse situation of low temperature of the wooden board.

[0021] 4. The present invention sets a focusing and irradiating mechanism. When the sliding rod slides in the hollow sliding groove, the positional relationship between the sliding rod and the scale groove can be observed. The farther the sliding rod is from the connecting sleeve, the more the hinged rod is pushed to rotate. This also means that the thicker the plate processed by the bottom of the high-precision cutting head, the deeper the penetration depth. This makes it easier for staff to quickly judge the high and low position status of the high-precision cutting head at this time, as well as the approximate thickness of the plate during cutting, which is more convenient for subsequent operations and processing.

[0022] 5. By setting up an irradiation adjustment mechanism in the present invention, when the high-precision cutting head rises away from the wooden board, the telescopic plate blocks less of the infrared thermal radiation lamp, so as to avoid the problem that when the high-precision cutting head descends to cut the wooden board, several infrared thermal radiation lamps of the thermal radiation mechanism rotate simultaneously towards the surface of the wooden board at the processing position for heating, which ultimately leads to excessive temperature and internal expansion of the wood, affecting its cutting accuracy. When the high-precision cutting head is away from the wooden board, the infrared thermal radiation lamp is completely opened for heating the wooden board by thermal radiation to ensure sufficient heating effect at a long distance, adapt to different working states and take corresponding heating measures to prevent accidents from occurring.

Specific implementation mode

[0037] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution: a sheet metal blanking device with a CAD comparison and calibration function, including a blanking machine 1, a first slider 5 is arranged on the top of the blanking machine 1, a second slider 6 is arranged on the top of the first slider 5, a cutting machine 7 is arranged on one side of the second slider 6, a high-precision cutting head 8 is fixedly connected to the output end of the cutting machine 7, a wooden part 9 is placed on the top of the blanking machine 1, and a thermal radiation mechanism 2 is arranged on the outer wall of the cutting machine 7;

[0038] The thermal radiation mechanism 2 includes:

[0039] Connecting sleeve 201, the connecting sleeve 201 is a circular ring structure, the inner wall of the connecting sleeve 201 is fixedly connected to the outer wall of the cutting machine 7, and an opening and closing plate 202 is arranged at the bottom of the connecting sleeve 201. The connecting sleeve 201 is used to connect the opening and closing plate 202 and the cutting machine 7;

[0040] Infrared thermal radiation lamp 203, the infrared thermal radiation lamp 203 is a square plate structure, the infrared thermal radiation lamp 203 is fixedly connected below the opening and closing plate 202, a rotating rod 204 is fixedly connected to one side of the opening and closing plate 202, and the opening and closing plate 202 is rotationally connected to the bottom of the connecting sleeve 201 through the rotating rod 204 on one side. The infrared thermal radiation lamp 203 is used to heat the wood;

[0041] When in use, first use CAD software to draw the drawing of the sheet metal to be cut, and then transfer the drawing to the control system of the blanking machine 1 through USB, network connection, etc.;

[0042] Comparison and calibration: After the control system of the device receives the drawing, it will automatically perform comparison and calibration, match the design size on the drawing with the actual size of the sheet metal to ensure the cutting accuracy;

[0043] Cutting and blanking: After completing the comparison and calibration, the equipment will automatically cut and blank according to the design on the drawing. During this process, the equipment uses a blanking machine 1 and a precise control system to ensure the accuracy and efficiency of cutting;

[0044] When performing cutting and blanking, the first slider 5 moves horizontally and laterally on the top of the blanking machine 1 under the control of the system, driving the second slider 6 to move. The second slider 6 controls the cutting machine 7 to move longitudinally on the surface of the first slider 5, and pushes the cutting machine 7 to perform lifting control through the second slider 6, realizing the final free movement and lifting of the cutting machine 7, and driving the high-precision cutting head 8 at the bottom to complete the blanking and cutting work on the wooden board below;

[0045] When cutting and blanking wooden boards in areas with relatively low ambient temperatures or in winter, before cutting the boards, the infrared thermal radiation lamp 203 is turned on in advance, so that the radiant heat energy radiated outward by the infrared thermal radiation lamp 203 is transferred to the wood below, and through the inclined surface of the opening and closing plate 202, the thermal radiation will preheat the position to be cut more concentratedly. Because as the temperature drops, the water in the wood cell wall begins to freeze, causing the wood volume to shrink and the density to increase. This shrinkage may cause changes in the size of the wood, thus affecting the accuracy of blanking. Prolonged exposure to low temperatures may cause the wood to deform, such as bending and twisting, which will also increase the difficulty and error of blanking. By heating, the shrinkage and deformation of the wood during cutting can be slowed down, thereby improving the accuracy and stability of blanking, and heating may reduce the hardness of the wood and make it softer, making it easier to cut. This helps to improve cutting efficiency, reduce tool wear, and then avoid the problem of accuracy loss under the action of CAD comparison and calibration;

[0046] Embodiment 2: Please refer to Figure 1-10 , based on Embodiment 1, the present invention provides a technical solution: A converging irradiation mechanism 3 is provided at the bottom of the connecting sleeve 201. The converging irradiation mechanism 3 includes a telescopic rod 301. The bottom of the telescopic rod 301 is fixedly connected to a connecting plate 302. The bottom of the connecting plate 302 is fixedly connected to a copper pressing plate 303. The copper pressing plate 303 is a square plate structure, and the copper pressing plate 303 is used to absorb heat.

[0047] On the outer wall of the connecting plate 302, there is a hinge rod 305 hinged through a rotating shaft 304. At the other end of the hinge rod 305, there is a sliding rod 306 fixedly connected. On one side of the connecting sleeve 201, there is a long plate 307 fixedly connected. Inside the long plate 307, there is a hollow sliding groove 308 opened. The sliding rod 306 is slidably connected to the inner wall of the hollow sliding groove 308. On the outer wall of the hinge rod 305, there is a sliding sleeve 309 slidably connected. On one side of the sliding sleeve 309, there is a pulling rope 310 fixedly connected. One end of the pulling rope 310 is arranged outside the opening and closing plate 202. The sliding sleeve 309 is used to play a role of sliding on the outer wall of the hinge rod 305.

[0048] On the top of the long plate 307, there is a scale groove 312 opened. On the outer wall of the sliding rod 306, there is a spring 311 fixedly connected. The spring 311 is used to pull the sliding rod 306 to play a role of resetting it. Inside the copper pressing plate 303, there is a first built-in spring.

[0049] The sliding sleeve 309 is of an annular sleeve structure. The scale groove 312 and the sliding rod 306 are used to observe the positional relationship between each other to play a role of judging the distance.

[0050] When the high-precision cutting head 8 descends to cut the plate, the copper pressure plate 303 will contact the surface of the wooden board, and because the first built-in spring inside the telescopic rod 301 will always push the connecting plate 302 and the copper pressure plate 303 against the bottom wooden board, as the high-precision cutting head 8 continues to descend, the telescopic rod 301 will be pressed and contracted because the copper pressure plate 303 is pressed, and one end of the hinged rod 305 will be driven to rise vertically through the connecting plate 302 and the rotating shaft 304, so that when one end of the hinged rod 305 rises, the sliding rod 306 at the other end will begin to slide outward in the hollow sliding groove 308 in the long board 307, and the pulling spring 311 will deform, so that the hinged rod 305 is hinged and rotated on the outer wall of the connecting plate 302, and the opening and closing plate 202 is pulled by the sliding sleeve 309 and the pull rope 310, and the sliding sleeve 309 can slide on the outer wall of the hinged rod 305, so the hinged rod 305 When the pull rope 310 is pulled to the opening and closing plate 202 by the sliding sleeve 309, the sliding sleeve 309 will naturally slide on the outer wall of the hinge rod 305 and present an angle state perpendicular to the pull rope 310 and the opening and closing plate 202, so that the infrared heat radiation lamp 203 under the opening and closing plate 202 will always face the bottom end of the hinge rod 305, and the bottom end of the hinge rod 305 is the position where the high-precision cutting head 8 needs to cut and process. Therefore, as the high-precision cutting head 8 descends, the opening and closing plate 202 will continue to rotate under the hinged rotation of the rotating rod 204, and keep the infrared heat radiation lamp 203 always facing the processing position of the high-precision cutting head 8 to complete the heating work for the area, so that when the position is changed by continuous lifting and cutting, the heat radiation will not lose a lot of heat energy due to the fixed angle and the wrong irradiation position during the frequent lifting and lowering process, resulting in poor heating effect and unstable heating effect.

[0051] When the heat radiation of the infrared heat radiation lamp 203 is irradiated onto the wooden board, a part of it will also be irradiated onto the connecting plate 302, and the heat will be efficiently absorbed by the connecting plate 302, so as to maintain a certain temperature of the connecting plate 302, so as to achieve that when the high-precision cutting head 8 frequently moves to cut the wooden board, the heating efficiency of the heat radiation is not enough to heat up the wooden board in the area around the high-precision cutting head 8, and the heat absorbed by the connecting plate is quickly released to the wooden board by contacting with the wooden board, so as to complete the heating effect of the wooden board with a lower temperature, and to achieve as much as possible under various working conditions, still ensure the stable heating effect of the wooden board, and then further avoid the unfavorable situation of low temperature of the wooden board;

[0052] And when the sliding rod 306 slides within the hollow chute 308, the positional relationship between the sliding rod 306 and the scale groove 312 can be observed. Since the farther the sliding rod 306 is from the connecting sleeve 201, it indicates that the articulated rod 305 is pushed to rotate more at the hinge, and also indicates that the thickness of the plate processed at the bottom of the high-precision cutting head 8 is thicker, and the penetration depth is deeper. This facilitates the staff to quickly judge the height position state of the high-precision cutting head 8 at this time, as well as the approximate thickness of the plate during cutting and processing, and is more convenient for subsequent operations and processing.

[0053] Embodiment 3: Please refer to Figure 1-13 , based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: An irradiation adjustment mechanism 4 is provided on the outer wall of the opening and closing plate 202. The irradiation adjustment mechanism 4 includes a first sliding frame 401, the first sliding frame 401 is slidably connected to the outer wall of the opening and closing plate 202, a pull rod 402 is fixedly connected to one side of the first sliding frame 401, the other end of the pull rod 402 is fixedly connected to a second sliding frame 403, the second sliding frame 403 is slidably connected to the outer wall of the opening and closing plate 202, a telescopic plate 404 is fixedly connected to the outer wall of the second sliding frame 403, and a fixed sleeve 405 is slidably connected to the outer wall of the telescopic plate 404.

[0054] One side of the fixed sleeve 405 is fixedly connected to the outer wall of the rotating rod 204, and the outer wall of the fixed sleeve 405 is fixedly connected to the outer wall of the opening and closing plate 202.

[0055] A second built-in spring is provided inside the fixed sleeve 405. One end of the second built-in spring is fixedly connected to one side of the telescopic plate 404, and the other side of the second built-in spring is fixedly connected to the inner wall of the fixed sleeve 405;

[0056] When the connecting sleeve 201 and the high-precision cutting head 8 descend, when using the high-precision cutting head 8 to cut the wooden board, the change in the angle of the articulated rod 305 will always pull the pull rope 310 to the first sliding frame 401, and the first sliding frame 401 will synchronously pull the pull rod 402, the second sliding frame 403, and the telescopic plate 404 to slide on the outer wall of the opening and closing plate 202. The telescopic plate 404 will slide out of the fixed sleeve 405 one by one, and will pull the second built-in spring in the fixed sleeve 405 and deform it. Therefore, the sliding sleeve 309 pulls the first sliding frame 401 through the pull rope 310, so that the opening and closing plate 202 inside the first sliding frame 401 is always pulled to drive the rotating rod 204 to rotate at the hinge, to change the angle between the opening and closing plate 202 and the infrared thermal radiation lamp 203, and when the telescopic plate 404 is pulled out of the fixed sleeve 405, it will cover the infrared thermal radiation lamp 203;

[0057] As the high-precision cutting head 8 descends more, the angle of rotation of the articulated rod 305 becomes larger. Then, the distance that the pull rope 310 is pulled by the sliding sleeve 309 and the first sliding frame 401 slides on the opening and closing plate 202 is also greater. Thus, when the high-precision cutting head 8 descends to cut the wooden board, the telescopic plate 404 will block the surface of the infrared thermal radiation lamp 203 to a certain extent. The more the high-precision cutting head 8 descends, the more the telescopic plate 404 blocks the surface of the infrared thermal radiation lamp 203. When the high-precision cutting head 8 rises away from the wooden board, the telescopic plate 404 blocks the infrared thermal radiation lamp 203 less, so as to avoid that when the high-precision cutting head 8 descends to cut the wooden board, several infrared thermal radiation lamps 203 of the thermal radiation mechanism 2 rotate simultaneously towards the surface of the wooden board at the processing position for heating, which ultimately leads to the problem of internal expansion of the wood due to excessive temperature and affects its cutting accuracy. When the high-precision cutting head 8 is away from the wooden board, the infrared thermal radiation lamp 203 is completely open for heating the wooden board by thermal radiation to ensure sufficient heating effect at a long distance, adapt to different working states and take corresponding heating measures to prevent accidents from occurring.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
