Description

Technical Field

[0001] The present invention belongs to the field of thermal cutting equipment, and specifically relates to a metal cardboard production and cutting device. Background Art

[0002] Metal cardboard is a composite material that contains both a metal layer and a cardboard layer. During the processing, due to the presence of metal materials, metal thermal cutting methods are generally used to process metal cardboard. Thermal cutting technologies mainly include arc cutting, plasma arc cutting, and laser cutting. All three technologies use heat energy to achieve material cutting and can be applied to the cutting of metal cardboard. When cutting metal cardboard, the metal cardboard is usually placed on a working platform, and a multi-axis moving thermal cutting head is used to flexibly cut the metal cardboard.

[0003] Metal cardboard is generally cut by thermal cutting methods. In traditional cutting equipment, the working platform for placing metal cardboard is generally horizontal, and multiple uniformly distributed support bars are arranged inside it. While supporting the metal cardboard, the gaps between the multiple support bars can facilitate the collection and discharge of waste, avoiding the influence of cutting debris on the cutting work of metal cardboard. There are various types of metal cardboard, and there are cases where irregular surfaces appear on the plate. Therefore, in traditional technologies, it is difficult to place metal cardboard to achieve the effect of first being horizontal and then cutting, thereby affecting the cutting of metal cardboard.

[0004] Therefore, the present invention provides a metal cardboard production and cutting device. Summary of the Invention

The fixed bar is located above the moving bar, and a pressure sensor is fixedly installed inside the fixed bar.

[0007] Preferably, a triangular tip bar I is fixedly installed above the fixed support bar. The top part of the lifting bar and the triangular tip bar I are made of the same structure, and the top of the triangular tip bar I is smoothly set.

[0008] Preferably, a sealing ring is installed between the triangular tip bar II and the fixed bar. The triangular tip bar II and the fixed bar are connected through the sealing ring, and the space between the triangular tip bar II and the fixed bar is filled with gas. A plurality of trapezoidal grooves are formed inside the fixed bar, and the pressure sensor is fixedly installed at the bottom of the trapezoidal groove.

[0009] Preferably, an L-shaped connecting rod is fixedly installed at the bottom of the moving bar. The L-shaped connecting rod is slidably installed at the inner bottom of the fixed table through the cooperation of a groove. One side of the L-shaped connecting rod is fixedly installed with a telescopic rod I, and the telescopic rod I is located inside the fixed table.

[0010] Preferably, a component groove is formed inside the fixed table. The pressing component is movably installed inside the component groove. The pressing component includes a displacement bar movably installed inside the component groove and a plurality of telescopic rods II fixedly installed on one side of the displacement bar. One end of each of the plurality of telescopic rods II is fixedly installed with a sliding platform. A pressing member is movably installed inside the sliding platform. The pressing component further includes a fixed motor fixedly installed on the side of the fixed table. One end of the shaft of the fixed motor is connected to a screw rod, and one end of the screw rod penetrates the fixed table and is helically connected to the displacement bar.

[0011] Preferably, the pressing member includes a plurality of rotating shafts rotatably installed inside the sliding platform. A transmission belt is rotatably installed outside the plurality of rotating shafts. The plurality of rotating shafts are at the same horizontal height, and the bottom horizontal height of the transmission belt is lower than the bottom horizontal height of the sliding platform.

[0012] Preferably, an air inner cavity is formed inside the fixed bar. A plurality of air grooves I are formed on both sides of the air inner cavity. The plurality of air grooves I penetrate the fixed bar. A plurality of air grooves II are formed at the bottom of the air inner cavity, and the plurality of air grooves II penetrate the fixed bar.

[0013] Preferably, a plurality of lifting grooves are penetrated through the inner sides of the fixed table, sliding bars are fixedly installed at both ends of the lifting bar, and the plurality of sliding bars are arranged to lift inside the corresponding plurality of lifting grooves. One end of the corresponding sliding bar is fixedly installed with an air pipe, and the air pipe is communicated with the corresponding air cavity. The plurality of air pipes are arranged downward and are connected to a suction structure arranged inside the device platform.

[0014] Preferably, the width of the moving bar is greater than the distance between two adjacent fixed bars, and the height of the triangular tip bar one is the same as the sum of the heights of the lifting bar and the moving bar.

[0015] Preferably, the multi-axis moving platform includes a vertical moving table movably installed above the device platform and a guide rail fixedly installed above the vertical moving table. A horizontal moving table is movably installed above the guide rail, and a thermal cutting head is fixedly installed above the horizontal moving table.

[0016] The beneficial effects of the present invention are as follows: 1. For a metal cardboard production and cutting device of the present invention, the lifting bar lifted by the moving bar rises to contact the lower side of the horizontal metal cardboard. Due to the irregular setting of the lower side of the metal cardboard, when the plurality of lifting bars contact the lower side of the metal cardboard, the heights of the plurality of lifting bars are different. And at this time, the pressure sensors inside the plurality of lifting bars will display pressure values. When the pressure value reaches a critical point, the moving bar is no longer driven to move to drive the corresponding lifting bar to rise. This critical point pressure value represents that when the metal cardboard is in a stretched horizontal state, the lifting bar on the lower side of the metal cardboard contacts and supports it, rather than breaking through this critical point and causing the rising of the lifting bar to damage the horizontal state of the metal cardboard or cause damage to it. At this time, even if the metal cardboard has an irregular surface, it will present a horizontal state on the fixed table, and then it is thermally cut by a thermal cutting head that can move in multiple axes.

[0017] 2. For a metal cardboard production and cutting device of the present invention, when the triangular tip bar two contacts and is pressed by the pressing component, at this time, the triangular tip bar two is pressed down, and the sealing ring is pressed and deformed, that is, the air pressure between the triangular tip bar two and the fixed bar increases. Because the pressure sensor is arranged at the bottom of the trapezoidal groove, after the gas is compressed, it will first enter the trapezoidal groove inside and cause a greater pressure on the pressure sensor, that is, the pressure value on the pressure sensor is greater. Through this way of gas pressing, a more comprehensive pressing effect can be exerted on the pressure sensor, accurately testing the data and prolonging its service life.

[0018] 3. In a metal cardboard production and cutting device according to the present invention, the electric extension of the second telescopic rod drives the sliding platform and the pressing member to move towards the metal cardboard until the pressing member is positioned above the corner of the metal cardboard. The sliding platform consists of two plates, and telescopic structures similar to electric telescopic columns are installed inside the two plates. A plurality of second telescopic rods are in contact with the upper plate of the sliding platform. Therefore, after the telescopic structure extends, the sliding platform drives the pressing member to press the metal cardboard. At this time, the transmission belt contacts a plurality of fixed support bars and lifting support bars or a plurality of lifting support bars. At this time, the surface of the transmission belt in contact with the fixed support bars and the lifting support bars is in a horizontal state. When the plurality of rotating shafts rotate to make the transmission belt rotate in the direction away from the metal cardboard, a stretching effect will be generated on the metal cardboard.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0023] Example 1: As Figure 1 and Figures 3 - 7 shown, a metal cardboard production and cutting device according to an embodiment of the present invention includes a device platform 4 and a multi-axis moving platform 3 movably installed above the device platform 4. A thermal cutting head 2 is installed above the multi-axis moving platform 3, and a cutting workbench 1 is installed above the device platform 4; The cutting workbench 1 includes a fixed table 11 and a pressing-down component 12 movably installed on both inner walls of the fixed table 11. A plurality of fixed support bars 13 are fixedly installed on both sides of the inner bottom of the fixed table 11, and a plurality of lifting support bars 14 are installed in the middle of the inner bottom of the fixed table 11; The lifting support bar 14 includes a moving bar 142 movably installed on the inner bottom of the fixed table 11 and a lifting bar 141 movably installed above the moving bar 142. The lifting bar 141 is installed in the fixed table 11 in a lifting manner. A plurality of fixed support bars 13 and a plurality of lifting support bars 14 are evenly distributed on the inner bottom of the fixed table 11. The lifting bar 141 includes a second triangular tip bar 1411 and a fixed bar 1412 installed below the second triangular tip bar 1411. The fixed bar 1412 is located above the moving bar 142, and a pressure sensor 143 is fixedly installed inside the fixed bar 1412.

[0024] Specifically, in the traditional technology, the metal cardboard is placed on the cutting workbench 1 to keep it in a horizontal state, and it is thermally cut by the multi-axis moving thermal cutting head 2. The thermal cutting head 2 is preferably in the form of laser cutting. The metal cardboard with an irregular surface is placed above the cutting workbench 1, that is, above the plurality of lifting support bars 14 or above the plurality of fixed support bars 13 and the lifting support bars 14. In the initial state, the plurality of fixed support bars 13 and the plurality of lifting support bars 14 are at the same horizontal height. The pressing component 12 is used to press and stretch, so that the metal cardboard is pressed and stretched above the fixed table 11. At this time, the pressing component 12 is in contact with the fixed support bar 13 or the fixed support bar 13 and some of the lifting support bars 14. The fixed support bar 13 is fixedly arranged, and the lifting support bar 14 is composed of a lifting bar 141 and a moving bar 142. The moving bar 142 can move on the inner bottom of the fixed table 11 by electric drive. When the pressing component 12 presses and contacts some of the lifting support bars 14, the pressure sensors 143 in these lifting support bars 14 will receive pressure and conduct pressure tests. The pressure sensors 143 in the lifting support bars 14 that simply contact the metal cardboard will also conduct pressure tests, but the pressure value in contact with the metal cardboard will be less than the pressure test value of the pressed part. At this time, through program control and numerical comparison, the lifting support bars 14 that are in contact with the irregular surface of the metal cardboard and have a small test value will work. The plurality of moving bars 142 in these lifting support bars 14 will move in the same direction from the initial position, that is, the top of the moving bar 142 does not contact the bottom of the lifting bar 141, but contacts the lifting bar 141 through the inclined surface of the moving bar 142. Since the lifting bar 141 is arranged to lift and lower inside the fixed table 11, at this time, the lifting bar 141 will vertically descend inside the fixed table 11, and the moving bar 142 always supports the lifting bar 141. By this way, the height of the lifting bar 141 is adjusted. The bar-shaped inclined surface of the moving bar 142 supports the bottom of the lifting bar 141, which can ensure that the moving bar 142 always fully supports the lifting bar 141, and retains the function of the gap between the fixed support bar 13 and the lifting support bar 14 for handling debris and waste. At this time, the lifting bar 141 in contact with the metal cardboard descends, which will cause the middle part of the metal cardboard not to contact anything except the pressed part, so it will sag. The pressing component 12 is used to stretch again, so that the metal cardboard with an irregular surface is in a horizontal state. Subsequently, the electric drive makes the moved moving bar 142 move in the same direction again, that is, move towards the original initial position until the lifting bar 141 lifted by these moving bars 142 rises and contacts the lower side of the horizontal metal cardboard. Due to the irregular setting of the lower side of the metal cardboard, when the plurality of lifting bars 141 contact the lower side of the metal cardboard, the heights of the plurality of lifting bars 141 are different, and at this time, the pressure sensors 143 inside the plurality of lifting bars 141 will display pressure values.When the pressure value reaches a critical point, the moving bar 142 is no longer driven to move to drive the corresponding lifting bar 141 to rise. This critical point pressure value represents that when the metal cardboard is in a stretched horizontal state, the lifting bar 141 on the lower side of the metal cardboard contacts and supports it, rather than breaking through this critical point and allowing the rise of the lifting bar 141 to damage the horizontal state of the metal cardboard or cause damage to it. At this time, even if the metal cardboard has an irregular surface, it will present a horizontal state on the fixed table 11. Subsequently, it is thermally cut by the multi-axis movable thermal cutting head 2, and the thermal cutting head 2 can also work by plasma arc cutting. Through the same implementation method, rapid cutting work can be carried out on different types of metal cardboards with irregular surfaces. By quickly horizontally supporting and placing different types of metal cardboards with irregular surfaces, the purpose of precise thermal cutting can be achieved. The generated chips and waste will be located in the gaps between the multiple fixed support bars 13 and the lifting support bars 14, which will not affect the thermal cutting effect and facilitate the subsequent discharge of chips and waste.

[0025] As Figures 8 - 9 shown, a triangular tip bar one 131 is fixedly installed above the fixed support bar 13. The top part of the lifting bar 141 and the triangular tip bar one 131 are components made of the same structure, and the top of the triangular tip bar one 131 is smoothly set.

[0026] A sealing ring 1413 is installed between the triangular tip bar two 1411 and the fixed bar 1412. The triangular tip bar two 1411 and the fixed bar 1412 are connected through the sealing ring 1413. Gas is stored between the triangular tip bar two 1411 and the fixed bar 1412. A plurality of trapezoidal grooves 144 are opened inside the fixed bar 1412, and the pressure sensor 143 is fixedly installed at the bottom of the trapezoidal groove 144.

[0027] An L-shaped connecting rod 1422 is fixedly installed at the bottom of the moving bar 142. The L-shaped connecting rod 1422 is slidably installed at the inner bottom of the fixed table 11 through the cooperation of the groove. A telescopic rod one 1421 is fixedly installed on one side of the L-shaped connecting rod 1422, and the telescopic rod one 1421 is located inside the fixed table 11.

[0028] Specifically, the triangular tip strip two 1411 and the fixed strip 1412 are connected by a sealing ring 1413. The gas is stored within the range wrapped by the sealing ring 1413, that is, maintained under certain air pressure conditions. At this time, the pressure sensor 143 displays a certain pressure value. When the triangular tip strip two 1411 contacts the downward pressing component 12 and is pressed downward, at this time, the triangular tip strip two 1411 is pressed downward, and the sealing ring 1413 is deformed by being pressed downward. That is, the air pressure between the triangular tip strip two 1411 and the fixed strip 1412 increases. Since the pressure sensor 143 is arranged at the bottom of the trapezoidal groove 144, after the gas is compressed, it will first enter the interior of the trapezoidal groove 144, causing a greater pressure on the pressure sensor 143. That is, the pressure value on the pressure sensor 143 is greater. Through this method of gas downward pressing, a more comprehensive downward pressing effect can be exerted on the pressure sensor 143, accurately testing the data and extending its service life. The triangular tip strip two 1411 that is contacted and pressed by the downward pressing component 12 will contact the metal cardboard, and not too much pressure will be exerted on this part of the triangular tip strip two 1411. Therefore, the test value of the pressure sensor 143 in contact with the metal cardboard is less than the test value of the pressure sensor 143 in the pressed part.

[0029] As Figures 10 - 12 shown, a component groove 112 is provided inside the fixed table 11, and the downward pressing component 12 is movably installed inside the component groove 112. The downward pressing component 12 includes a displacement strip 122 movably installed inside the component groove 112 and a plurality of telescopic rods two 123 fixedly installed on one side of the displacement strip 122. One end of the plurality of telescopic rods two 123 is fixedly installed with a sliding platform 125. A downward pressing component 126 is movably installed inside the sliding platform 125. The downward pressing component 12 further includes a fixed motor 121 fixedly installed on the side of the fixed table 11. The end of the fixed motor 121 is connected to a screw rod 124 through a shaft, and one end of the screw rod 124 penetrates the fixed table 11 and is in threaded connection with the displacement strip 122.

[0030] The downward pressing component 126 includes a plurality of rotating shafts 1261 rotatably installed inside the sliding platform 125. A transmission belt 1262 is rotatably installed outside the plurality of rotating shafts 1261. The plurality of rotating shafts 1261 are at the same horizontal height, and the bottom horizontal height of the transmission belt 1262 is lower than the bottom horizontal height of the sliding platform 125.

[0031] Specifically, when multiple fixed support bars 13 and lifting support bars 14 are at the same horizontal height, the metal cardboard is initially placed on multiple fixed support bars 13 and lifting support bars 14. At this time, according to the placement position of the metal cardboard, the screw rod 124 is rotated by the drive of the fixed motor 121, thereby driving the displacement bar 122 and the sliding platform 125 to move inside the component groove 112, so that the position of the pressing component 126 corresponds to that of the metal cardboard. Subsequently, the telescopic rod II 123 is electrically extended to drive the sliding platform 125 and the pressing component 126 to move towards the metal cardboard until the pressing component 126 is above the corner of the metal cardboard. The sliding platform 125 is composed of two plates, and a telescopic structure similar to an electric telescopic column is installed inside the two plates. Multiple telescopic rods II 123 are in contact with the upper plate of the sliding platform 125. Therefore, after the telescopic structure extends, the sliding platform 125 drives the pressing component 126 to press the metal cardboard. At this time, the transmission belt 1262 is in contact with multiple fixed support bars 13 and lifting support bars 14 or multiple lifting support bars 14. At this time, the surface of the transmission belt 1262 in contact with the fixed support bars 13 and lifting support bars 14 is in a horizontal state. When multiple rotating shafts 1261 rotate to make the transmission belt 1262 rotate in the direction away from the metal cardboard, a stretching effect will be generated on the metal cardboard.

[0032] As Figure 2 shown, the multi-axis moving platform 3 includes a vertical moving platform 31 movably installed above the device platform 4 and a guide rail 32 fixedly installed above the vertical moving platform 31. A horizontal moving platform 33 is movably installed above the guide rail 32, and a thermal cutting head 2 is fixedly installed above the horizontal moving platform 33.

[0033] Embodiment 2: As Figures 8 - 10 shown, compared with Embodiment 1, another implementation manner of the present invention is: an air cavity 145 is opened inside the fixed bar 1412, and a plurality of air grooves I 1451 are opened on both sides of the air cavity 145. A plurality of air grooves I 1451 penetrate through the fixed bar 1412, and a plurality of air grooves II 1452 are opened at the bottom of the air cavity 145, and a plurality of air grooves II 1452 penetrate through the fixed bar 1412.

[0034] A plurality of lifting grooves 111 are penetrated through both inner sides of the fixed platform 11. Sliding bars 15 are fixedly installed at both ends of the lifting bar 141. A plurality of sliding bars 15 are arranged to lift inside the corresponding plurality of lifting grooves 111. One end of the corresponding sliding bar 15 is fixedly installed with an air pipe 16, and the air pipe 16 is communicated with the corresponding air cavity 145. A plurality of air pipes 16 are arranged downward and are connected to the air suction structure arranged inside the device platform 4.

[0035] The width of the moving bar 142 is greater than the spacing between two adjacent fixed bars 1412, and the height of the triangular tip bar one 131 is the same as the sum of the heights of the lifting bar 141 and the moving bar 142.

[0036] Specifically, on the premise that the moving bar 142 moves, the lifting bar 141 vertically ascends and descends inside the fixed table 11 through the cooperation of the sliding bar 15 and the lifting groove 111. When the moving bar 142 moves to the limit position through the extension of the telescopic rod one 1421, a lifting bar 141 will descend to the limit position and contact the inclined surfaces of two adjacent moving bars 142. At this time, multiple air grooves two 1452 opened at the inner bottom of the lifting bar 141 will face the inner bottom of the fixed table 11, and the suction structure inside the fixed table 11 will take effect. The gas inside the air cavity 145 is sucked through the air pipe 16, so that multiple air grooves two 1452 generate suction force to collect and discharge the debris and waste at the inner bottom of the fixed table 11. Compared with the traditional technology, the distance between the air port and the inner bottom of the fixed table 11 in this case is closer, and the cleaning can be effectively and comprehensively carried out. At this time, multiple air grooves one 1451 can also collect and discharge the debris and waste on the inclined surfaces of adjacent moving bars 142. Moreover, when the same lifting bar 141 and the moving bar 142 are in any state, multiple air grooves two 1452 and air grooves one 1451 can generate suction effects.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
