[0001] The utility model relates to pipe positive pressure flat technology field more specifically, relate to a kind of laser cutting machine's coiled material pipe positive pressure flat mechanism. BACKGROUND

[0002] With the continuous progress of industrial manufacturing, laser cutting technology is widely used in many fields due to its high precision, high speed and flexibility. During the laser cutting process, coiled material pipe as a common raw material, its quality and state have a key influence on cutting effect. High-quality cutting requires coiled material pipe to have a flat surface to ensure that the laser beam can be accurately focused and uniformly act on the material, thereby achieving accurate cutting profile and good cutting quality. However, coiled material pipe often bends, deforms or has uneven surface during production, transportation or storage, which poses a challenge to the laser cutting process.

[0003] Currently, before using a laser cutting machine to cut coiled material into sheet-shaped finished products, the coiled material needs to be unwound and flattened before the sheet enters the cutting chamber. Because the bending degree of the sheet in the coiled state is too high, a pinch roller is generally used to pinch and flatten the sheet during flattening. However, the coiled material is in a state of bending for a long time before cutting, and the coiled material is greatly affected by its own elastic force. When unwinding and flattening, it is difficult to flatten the coil in a limited space using only a pair of pinch rollers.

[0004] The utility model can make coiled material more convenient and stable when flattening. UTILITY MODEL CONTENT

[0015] Beneficial effects:

[0016] 1. By setting a limiting group, using the limiting plate in the limiting group at the upper end of the workbench, the preliminary limiting effect of the coil pipe is realized, and the two sides of the rotating rod further enhance the stability of the limiting plate. The screw rod can realize the up-down position adjustment of the limiting plate under the drive of motor two, which can ensure that the coil pipe is always in the appropriate position during the transmission and flattening process. When the coil pipe passes through, the scraper can effectively remove the impurities, dust and other foreign matters on the surface of the coil pipe, ensuring the cleanliness of the coil pipe surface. The clean coil pipe surface is conducive to the accuracy of subsequent flattening and laser cutting operations, reduces the problems of uneven cutting surface or poor flattening effect caused by impurity particles, and improves the quality of the entire processing process. The compression roller is installed on the side of the scraper. When the coil pipe passes through the limiting group during the transmission process, the compression roller will exert a certain pressure on the coil pipe, thereby playing a role in flattening the coil pipe.

The inner side of the clamping plate is provided with an auxiliary roller, and the outermost end of the auxiliary roller protrudes from the inner side of the clamping plate.

While ensuring the clamping effect, the integrity and quality of the coil pipe are effectively protected, ensuring that the quality of the coil pipe is not affected during the entire processing process, which is conducive to improving the quality of the final product. The clamping plate can limit the coil pipe, so that the coil pipe can remain stable when subjected to pressure and will not deform or slide, thereby improving the stability and reliability of the entire flattening process and ensuring the accuracy and efficiency of the flattening operation;

DETAILED DESCRIPTION

[0024] The utility model embodiment will be combined with the drawings of the utility model embodiment below. Figures 1-4 The technical scheme in the utility model embodiment is clearly and completely described.

[0025] Please refer to Figures 1-4The utility model discloses a kind of flat mechanisms of positive pressure of coiled material tube of laser cutting machine, comprising: workbench 1, workbench 1, workbench 1 left and right two ends are provided with support 2, and the upper end of workbench 1 is provided with multiple limiting groups 3, and limiting group 3 one side is provided with clamping plate 4;Support 2 outside is provided with motor one 201, support 2 inside is provided with rotating roller 202 and adjusting roller 203, the output end of motor one 201 is connected with the rotating shaft of rotating roller 202, and rotating roller 202 is below adjusting roller 203;Limiting group 3 includes limiting plate 301, scraper 302 and press roller 303, limiting plate 301 is located on the upper end of workbench 1, scraper 302 is installed at the bottom of limiting plate 301, and press roller 303 is installed at the side of scraper 302;

[0026] The workbench 1 is the basic support part of the whole mechanism, which provides a stable flat platform for the processing operation of the coil pipe. The bracket 2 is arranged at the left and right ends of the workbench 1, which plays a supporting and fixing role for other components. The motor 201 is installed outside the bracket 2, which mainly provides power source for the rotating roller 202. After the motor 201 is started, the output end drives the rotating shaft of the rotating roller 202 to rotate, so that the rotating roller 202 can rotate according to the set requirements. During the whole process of the coil pipe being pressed flat, the rotating roller 202 drives the coil pipe to move through its rotation, and at the same time, the coil pipe is pressed flat. The rotating roller 202 is one of the important power components for the transmission of the coil pipe in the mechanism. The adjusting roller 203 adjusts the distance between the rotating roller 202 or the relative rotation speed to ensure that the coil pipe maintains a suitable state during the transmission process, so that the subsequent flattening process can be smoothly carried out, and the device can be adjusted according to different coils, so that the device is more flexible in use. The limiting group 3 is composed of a limiting plate 301, a scraper 302 and a pressing roller 303, which is arranged at the upper end of the workbench 1, and a clamping plate 4 is arranged on one side of each limiting group 3. The main function of the limiting group 3 is to limit and process the position and shape of the coil pipe on the workbench 1, so as to ensure that the coil pipe can be flattened in the expected way. The limiting plate 301 is located at the upper end of the workbench 1, which is an important part of the limiting group 3, and plays a preliminary limiting role for the whole limiting group 3. The scraper 302 is installed at the bottom of the limiting plate 301, which can scrape off some impurities, dust and other foreign matters on the surface of the coil pipe when the coil pipe passes through, so as to ensure the cleanliness of the surface of the coil pipe, which is beneficial to the accuracy of the subsequent flattening and laser cutting operations, and also plays a role in assisting flattening. The pressing roller 303 is installed on the side of the scraper 302. When the coil pipe passes through the limiting group 3 during the transmission process, the pressing roller 303 will exert a certain pressure on the coil pipe, so as to play a role in flattening the coil pipe, so that the coil pipe can be made more flat to a certain extent before entering the subsequent more delicate flattening or cutting process, which is convenient for the smooth development of the subsequent operation. The clamping plate 4 is arranged on one side of the limiting group 3, which usually cooperates with the limiting group 3 to further fix and limit the coil pipe. For example, before the pressing roller 303 flattens the coil pipe, the clamping plate 4 can limit the coil pipe to prevent it from sliding or deforming horizontally when subjected to pressure, so as to ensure that the flattening operation is accurate and the coil pipe is more flexible during flattening.

[0027] The utility model discloses a support 2 inside is provided with the adjusting plate 204, the adjusting plate 204 bottom is provided with the locating plate 205, the pivot of adjusting roller 203 can penetrate the both ends of locating plate 205, and adjusting roller 203 and the locating plate 205 between are movably connected, and the both sides of support 2 are provided with the sliding slot 206, and the both ends of adjusting plate 204 are provided with the lug 207, and the lug 207 can be embedded in the inside of sliding slot 206, and the lug 207 and the sliding slot 206 between are movably connected, and support 2 inside is provided with the hydraulic rod 208, and the hydraulic rod 208 other end is installed on the adjusting plate 204 upper end, the adjusting plate 204 sets up in support 2 inside, realizes the adjusting function to adjusting roller 203 through the position change of self on support 2, and the locating plate 205 is located at the bottom of adjusting plate 204, and its main role is to provide support and positioning for the pivot of adjusting roller 203, and the pivot of adjusting roller 203 can penetrate the both ends of locating plate 205, and adjusting roller 203 and the locating plate 205 between are movably connected, so that adjusting roller 203 can rotate flexibly relative to the locating plate 205 in the operation process, guarantee its normal working condition, such as when cooperating with the rotating roller 202 and drive the coil tube flat moving operation can smoothly carry out the rotating action, and the locating plate 205 also ensures the position stability of adjusting roller 203 to a certain extent, and the sliding slot 206 is set up in the both sides of support 2, and is the structure that is provided with for realizing the movability of adjusting plate 204 in support 2, and it provides the guiding and limiting action for the movement of adjusting plate 204, so that adjusting plate 204 can only move according to the direction defined by sliding slot 206, guarantees the accuracy and stability of adjusting, and the lug 207 sets up in the both ends of adjusting plate 204, and can be embedded in the inside of sliding slot 206, and the lug 207 and the sliding slot 206 between are movably connected, when the adjusting plate 204 needs to carry out position adjustment, the lug 207 slides in the sliding slot 206, thereby drives adjusting plate 204 and adjusting roller 203 along the direction of sliding slot 206 and moves, and this connecting mode guarantees that adjusting plate 204 can move flexibly relative to support 2, and can prevent adjusting plate 204 from deviating or separating from support 2 during the movement and other unstable conditions, so that adjusting roller 203 is more flexible when using, and the hydraulic rod 208 is installed in support 2 inside, and its other end is connected on the adjusting plate 204 upper end, and the hydraulic rod 208 is the power source that realizes the position movement of adjusting plate 204, by controlling the extension and contraction of hydraulic rod 208, can push or pull adjusting plate 204 and move along the direction of sliding slot 206 in support 2 inside, when the hydraulic rod 208 lengthens, will push adjusting plate 204 and move upwards.When the hydraulic rod 208 is shortened, the adjusting plate 204 will be pulled to move downward. Since the movement of the adjusting plate 204 will drive the bottom positioning plate 205 and the adjusting roller 203 connected thereto to move, the operation of the adjusting plate 204 by the hydraulic rod 208 can realize the position adjustment of the adjusting roller 203 in the vertical direction. Such adjustment function is very important in the whole coiled pipe positive flattening mechanism. For example, according to different thicknesses, materials and other conditions of the coiled pipe, the spacing between the adjusting roller 203 and the rotating roller 202 can be flexibly adjusted, so as to achieve the best coiled pipe transmission and flattening effect, etc., so as to ensure that the whole mechanism can adapt to different working requirements, effectively process the coiled pipe, and better adapt to various processing requirements of the coiled pipe in the coiled pipe positive flattening mechanism of the laser cutting machine.

[0028] The utility model discloses an embedded connection plate is arranged in the bottom end of the workbench, and the connection plate is consistent with the shape of the scraper, and the inner side of the scraper is conical, and the position of the connection plate corresponds to the scraper, and the both sides of the limiting plate are provided with the rotating rod and the screw rod, and one end of the screw rod is provided with the motor no.The connecting plate 101 is embedded in the inner bottom end of the workbench 1, which is consistent in shape with the scraper plate 302, and the consistent shape enables them to cooperate with each other in function. The connecting plate 101 plays an auxiliary role for the scraper plate 302, such as providing certain support from below or synergistic effect when the scraper plate 302 is scraping impurities on the pipe, so as to ensure that the scraper plate 302 can more stably and effectively complete its function. The scraper plate 302 is installed at the bottom of the limiting plate 301, and the inner side is conical. When the pipe passes through the scraper plate 302 during transmission, the conical inner side can better fit the outer surface of the pipe, so that the operation of scraping impurities is more thorough. Because the conical surface can more comprehensively contact along the circumferential direction of the pipe, it can more effectively scrape off the dust, debris and other impurities attached to the surface of the pipe, thereby ensuring the cleanliness of the pipe surface and providing good conditions for subsequent flattening, cutting and other operations. At the same time, the connecting plate 101 and the scraper plate 302 clamp the flattened pipe, so that the pipe is more efficient when flattened, and to some extent, the flattening quality of the device is improved. The limiting plate 301 is an important part of the limiting group 3. In addition to limiting the transverse position of the pipe, a rotating rod 304 and a screw rod 305 are also provided on both sides of the limiting plate 301. The rotating rod 304 penetrates the limiting plate 301, and the rotating rod 304 further limits the limiting plate 301, so that the limiting plate 301 is more stable when moving. One end of the screw rod 305 is provided with a motor 306, which can provide power for the rotation of the screw rod 305. When the motor 306 is started, the screw rod 305 will rotate. Through the thread cooperation between the screw rod 305 and the limiting plate 301, the position of the limiting plate 301 can be adjusted up and down, so that the position of the limiting plate 301 can be flexibly changed, thereby more accurately limiting the pipe. Ensure that the pipe is always in the right position during transmission and flattening, so that subsequent operations can be carried out smoothly. The spring 307 is fixedly installed at both ends of the rotating shaft of the compression roller 303, and one end of the spring 307 is installed in the inner side of the limiting plate 301. The spring 307 plays an important role in buffering and self-adaptive adjustment during the operation of the compression roller 303. When the compression roller 303 flattens the pipe, the spring 307 can automatically adjust according to the actual pressure of the pipe. For example, if the pipe is thicker at a certain position, the spring 307 will be compressed accordingly when the compression roller 303 is pressed down, so that the compression roller 303 can better adapt to the change of the pipe and maintain the effective flattening pressure of the pipe. Without the local difference of the pipe, the compression roller 303 cannot work normally or cause excessive extrusion of the pipe, which prolongs the service life of the compression roller 303 and related parts, and more accurately limits, cleans and flattens the pipe to adapt to different pipe characteristics and provide better preparation conditions for subsequent laser cutting and other processes.

[0029] In the embodiment of the utility model, the clamping plate 4 can be embedded in the inner side of the workbench 1, and an electric telescopic rod 401 is arranged between the clamping plate 4 and the workbench 1, and the electric telescopic rod 401 can be embedded in the inner side of the workbench 1, one end of the clamping plate 4 is in a conical shape, an auxiliary roller 402 is arranged in the inner side of the clamping plate 4, and the outermost end of the auxiliary roller 402 protrudes from the inner side of the clamping plate 4; the clamping plate 4 can be embedded in the inner side of the workbench 1, so that the clamping plate 4 can further limit the flattened coiled material, preventing the coiled material from deviating in position when moving, when it is necessary to clamp the coiled material pipe, the clamping plate 4 can be extended from the inner side of the workbench 1 and exert its clamping function, the electric telescopic rod 401 is arranged between the clamping plate 4 and the workbench 1, and the electric telescopic rod 401 is the power source for realizing the telescopic action of the clamping plate 4, which can be embedded in the inner side of the workbench 1, ensuring the compactness of the overall structure and controlling the extension and retraction action of the clamping plate 4 through the telescopic action of the electric telescopic rod 401, when the electric telescopic rod 401 is extended, the clamping plate 4 is pushed out from the inner side of the workbench 1, so that it can be close to and clamp the coiled material pipe; when the electric telescopic rod 401 is shortened, the clamping plate 4 is pulled back to the inner side of the workbench 1 and restored to the storage state, when the clamping plate 4 is close to the coiled material pipe under the pushing of the electric telescopic rod 401, it is ensured that the clamping plate 4 can effectively clamp the coiled material pipe, preventing the coiled material pipe from sliding or deviating in the subsequent flattening, cutting and other operation processes, the auxiliary roller 402 is arranged in the inner side of the clamping plate 4, and the outermost end of the auxiliary roller 402 protrudes from the inner side of the clamping plate 4, and the auxiliary roller 402 is mainly arranged to reduce the friction between the clamping plate 4 and the coiled material pipe when the clamping plate 4 clamps the coiled material pipe, so that the coiled material pipe can still move relatively smoothly in the clamped state, when the coiled material pipe needs to pass through the clamping area of the clamping plate 4 in the transmission process, the auxiliary roller 402 contacts the surface of the coiled material pipe, since the auxiliary roller 402 can roll, it can convert the original sliding friction between the clamping plate 4 and the coiled material pipe into rolling friction, reducing the friction loss, and at the same time, it is also helpful to protect the surface of the coiled material pipe, avoiding scratches and other damages on the surface of the coiled material pipe due to excessive friction, thereby ensuring the integrity and quality of the coiled material pipe in the whole processing process, and making the device more stable and convenient when flattening the coiled material.

[0030] Working principle: the position of the adjusting plate 204 is adjusted by the hydraulic rod 208, so that one end of the coiled material is located between the adjusting roller 203 and the rotating roller 202. The motor 201 starts to drive the rotating roller 202 to rotate, which cooperates with the coiled material tube to move on the workbench 1. In the moving process, the scraper 302 performs preliminary processing on the coiled material tube. The inner tapered structure can effectively fit the outer surface of the coiled material tube, and can scrape off dust, debris and other impurities. At the same time, it cooperates with the connecting plate 101 in the workbench 1, which provides support for the scraper 302. The two can also clamp the coiled material tube to improve the efficiency and quality of flattening, and ensure the surface of the coiled material tube clean, creating conditions for subsequent operation. The limiting plate 301 is stabilized and position adjusted under the action of the rotating rod 304 and the screw rod 305. The rotating rod 304 can enhance the stability of the limiting plate 301. The motor 306 drives the screw rod 305 to rotate, and moves the limiting plate 301 up and down through the thread cooperation, so as to accurately limit the position of the coiled material tube, and ensure that it is in the appropriate position during transmission and flattening. The adjusting roller 203 adjusts the distance or rotating speed with the rotating roller 202 under the cooperation of the hydraulic rod 208, the adjusting plate 204 and the positioning plate 205. The hydraulic rod 208 pushes or pulls the adjusting plate 204 to move in the sliding groove 206 of the support 2, and then drives the adjusting roller 203 connected with the positioning plate 205 at the bottom of the adjusting plate 204 to change the position in the vertical direction, so as to adapt to coiled material tubes with different thickness and material, and ensure that the coiled material tube is in good transmission and flattening state. The compression roller 303 applies pressure to the coiled material tube when it passes through the limiting group 3 to flatten it. The springs 307 at both ends of the compression roller 303 can automatically stretch and contract according to the pressure condition of the coiled material tube. If the local thickness of the coiled material tube changes, the spring 307 adjusts accordingly to maintain effective flattening pressure, avoid abnormal compression roller 303 and damage to the coiled material tube, and prolong the service life of the component. The clamping plate 4 is driven by the electric telescopic rod 401 to extend or retract from the inside of the workbench 1. The tapered end is convenient for accurate insertion and positioning, so as to clamp the coiled material tube. The auxiliary roller 402 in the inside of the clamping plate 4 contacts with the coiled material tube, which changes the sliding friction into rolling friction, reduces the friction force, and enables the coiled material tube to move smoothly in the clamped state, preventing it from sliding or moving in the subsequent operation, ensuring stable and convenient flattening operation. Through the cooperation of various components, the coiled material tube material with flat, accurate position and clean surface is prepared for the subsequent laser cutting process.
