Description

Technical Field

[0001] The invention belongs to the technical field related to template cutting production, and in particular relates to a stainless steel template laser cutting device and process. Background Art

[0002] Stainless steel formwork is a formwork used in construction, usually made of stainless steel. It has the characteristics of high strength, corrosion resistance, and wear resistance. Therefore, it is widely used in concrete pouring in construction projects. Stainless steel formwork can improve construction efficiency and ensure the quality and appearance of concrete structures.

[0003] In order to produce high-precision stainless steel templates, the stainless steel templates need to be laser cut. Laser cutting is a thermal cutting method that heats the workpiece through a high-energy-density laser beam to quickly melt or vaporize the material, thereby forming an incision. Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can achieve better cutting quality. The laser cutting incision is narrow, the two sides of the cut are parallel and perpendicular to the surface, and the cutting accuracy is high. During laser cutting, the cutting torch does not contact the workpiece, and there is no tool wear. When processing parts of different shapes, there is no need to replace the "tool", only the output parameters of the laser need to be changed. The laser cutting process has low noise, small vibration, and no pollution. When processing parts of different shapes, there is no need to replace the "tool", only the output parameters of the laser need to be changed. The laser cutting process has low noise, small vibration, and no pollution. It can be well applied to the cutting operation of stainless steel templates.

[0004] After searching Chinese patents, a utility model patent with patent number CN218533212U discloses a laser cutting device for flexible manufacturing of steel templates, including a cutting mechanism, a moving mechanism, and an expansion mechanism for expanding the working platform according to the size of the material; the expansion mechanism is arranged below the moving mechanism, and the cutting mechanism is arranged above the moving mechanism; the expansion mechanism includes a second support frame, the second support frame is arranged below the moving mechanism, a plurality of second telescopic rods are arranged longitudinally on both sides of the second support frame, a baffle is arranged at the output end of the second telescopic rod, a second connecting frame is arranged on one side of the baffle, a plurality of second support rods are arranged longitudinally below the second connecting frame, and a pulley is arranged below the second support rod. When in use, according to the size of the steel template material, the baffle is driven by the second telescopic rod to move horizontally, and the baffle drives the second support rod and the pulley to move horizontally through the second connecting frame, so as to change the size of the working platform. However, the template laser cutting device still has the following disadvantages in actual use: In the process of laser cutting of stainless steel templates, the template is directly placed on the cutting equipment, and the position is determined by the clamping device before the cutting operation is carried out. However, when the template is clamped by the clamping device, in order to clamp it, the template needs to be clamped and slightly squeezed or stretched, causing the stainless steel template to deform, affecting the cutting accuracy of the stainless steel template. After laser cutting, the cut part is separated from the template. After separation, the required part of the template is usually directly transported to the next processing equipment through the conveying device, and the unnecessary part falls directly into the collection equipment. In this process, the cut part of the template is easily deformed under the influence of gravity, causing the cutting position on the template to deform. Summary of the invention

After cutting is completed, servo motor one is started. At this time, the cut template falls on the supporting roller and moves to the next processing equipment under the drive of servo motor one.

After working for a period of time, servo motor two is started, and the roller is driven by servo motor two to rotate, the fireproof mat is rolled up, and the chips on the fireproof mat are scraped off by a scraper.

[0011] Furthermore, a push plate is commonly fixed to the ends of the three piston rods passing through the same support plate, and the two push plates are both arranged above the two support frames. Limit blocks are fixed at the edges of the short sides of the two push plates close to each other and close to the fixed frames, so that when working, the push plate is driven to move by the piston rod, which drives the limit block to move, and the movement position of the template in the support frame is limited by the limit block, which facilitates the accurate positioning of the template in the support frame.

[0012] Furthermore, a pull rope is fixed to one end of the fireproof pad away from the roller, and a pull ring is fixed to one end of the pull rope away from the fireproof pad. When the fireproof pad is working, the pull rope and the pull ring cooperate so that it can be reset by pulling after being rolled up.

[0013] Furthermore, a motor base 2 is fixed to the bottom of the servo motor 2, the roller is rotatably connected in the fixed frame, and the servo motor 2 is supported on the ground through the motor base 2.

[0014] Furthermore, a telescopic rod is fixed at equal intervals along a center line parallel to the long side at one end of the fixing strip away from the roller, a compression spring is fixed to the fixing strip outside the telescopic rod, the telescopic end of the telescopic rod and the end of the compression spring away from the fixing strip are both fixed to a side wall of the fixing frame away from the support frame, and the position of the fixing strip in the fixing frame is determined by the cooperation of the telescopic rod and the compression spring, so that the contact between the cutter and the rolled-up fireproof pad on the roller is maintained during operation.

[0015] Furthermore, a mounting plate is fixed at the lower edge of the vertical portion of the L-shaped connecting plate away from the electric push rod, and the laser cutting head is fixed in the mounting plate. An optical cable is fixed at the top of the laser cutting head, so that when working, the optical cable transmits the laser to the laser cutting head to cooperate with the laser cutting function.

[0016] Furthermore, a stainless steel template laser cutting device and process includes the following process flow: S1: During operation, first determine the shape and position of the template to be cut. Push the support roller position on the shaft in the support frame to ensure that the cut sheet is supported by the roller after the template is cut. When the roller position changes after cutting a sheet, push the roller to the appropriate position again to proceed to the next step. S2: After the setting of the support roller is completed, the pneumatic push rod can be started immediately, and the pneumatic push rod drives the piston rod to move, and the piston rod pushes the push plate to move toward the inner center of the support frame, and is set outside the position where the stainless steel template needs to be cut, so that the distance between the two push plates is greater than the width of the stainless steel template; S3: At the same time, the template is transported from the external transport structure to the support frame and supported by the support rollers on the rotating shaft. When the servo motor is driven, the template to be cut is driven to move until the template contacts the limit block. After the end position of the template is determined by the limit block, the servo motor is stopped. S4: Then restart the pneumatic push rod to drive the push plate to move to clamp the template to be laser cut, so that the position of the template is determined in the side position in the support frame, and then start the pneumatic push rod to drive the push plate to leave the template to be cut, completing the positioning of the template; S5: After the template is positioned, laser cutting can be carried out. During laser cutting, the moving assembly is controlled by the C1SG PLC, and the electric hoist 1 on track 1 and the electric hoist 2 on track 2 are started at the same time, so that the electric push rod moves to the appropriate position on the template to be cut, so that the cutting focus of the laser cutting head is set above the cutting starting point of the template; S6: After the electric push rod is moved, the electric push rod drives the piston rod 2 to descend, driving the L-shaped connecting plate to descend until the cutting focus of the laser cutting head on the mounting plate driven by the L-shaped connecting plate falls on the stainless steel template to be cut in the support frame; S7: Cutting starts. During the cutting process, the C1SG PLC controls the movement of the electric hoist 1 and the electric hoist 2, so that the laser cutting head moves along a suitable cutting track on the stainless steel template in the support frame and cuts the template into a suitable shape. S8: After the cutting is completed, the servo motor 1 can be started to drive the rotating shaft to rotate, and the supporting roller can be driven to rotate, so that the stainless steel template after laser cutting and the cut template waste are transported to the next processing equipment together. When the template passes through the gap between the supporting frame and the next processing equipment, the cut part of the template is separated from the template, and the template moves directly to the next processing equipment; S9: While the template is being transported, the next stainless steel template to be cut is aligned with the support frame, and the above steps of positioning and cutting the stainless steel template are repeated to complete the stainless steel template cutting cycle. During the process of cutting the template with the laser cutting head, the dust and scraps generated by the cutting directly fall on the fireproof pad in the support frame. S10: After a certain number of working cycles, the cutting operation is stopped first, and then the servo motor 2 is started, and the servo motor 2 drives the driving shaft to rotate, driving the roller to rotate, and the fireproof pad is driven to be wound around the roller through the rotation of the roller; S11: When the fireproof mat is wound, the scraper on the fixed strip in the fixed frame is always pressed against the surface of the fireproof mat during the winding process, and the dust and waste on the surface of the fireproof mat are scraped off and guided to the fixed frame through the fixed strip to complete the surface cleaning of the fireproof mat; S12: After the surface of the fireproof mat is cleaned, restart the servo motor 2 to drive the roller to rotate in the opposite direction, and at the same time pull the pull ring, pull the pull rope and the fireproof mat to pull the fireproof mat back into the support frame, and smooth the edges and corners of the fireproof mat, and then resume the cutting operation of the stainless steel template.

[0017] The present invention has the following beneficial effects: The present invention solves the problem that the cutting accuracy is affected by the deformation of the template due to clamping and the cutting position is easily deformed without good support by arranging a support frame, a servo motor, a pneumatic push rod, a moving component, an electric push rod and a limit block. After the servo motor drives the roller to drive the template to move to contact the two limit blocks, the pneumatic push rod is started again, and the pneumatic push rod drives the push plate to drive the stainless steel template to move on the support roller to fine-tune to a suitable position. Then the pneumatic push rod is started to drive the piston rod to drive the push plate to move until the distance between the two limit blocks is greater than the width of the stainless steel template, and the template can be cut. At this time, the moving component is driven by the C1S The G model is controlled by PLC, which drives the electric push rod to drive the lifting cutting head to cut, and cuts the template into a suitable shape, so that the template is not subjected to clamping pressure such as squeezing and stretching during the cutting operation, and the cutting accuracy is better. After the stainless steel template is cut by the laser cutting head, the cut part is supported by the support roller to determine the position. After the cutting is completed, the shaft is driven to rotate by multiple servo motors, driving the support roller to rotate, and the cut template and the cut part of the template are output. In this way, the cut part of the template can be well supported during the cutting process to prevent deformation of the cutting position caused by gravity, and it can also be well transported after cutting.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-3 The present invention is a stainless steel template laser cutting device, including a support frame 1 and a servo motor 2. The support frame 1 is supported on the ground by a support seat 102 at the bottom thereof. At the same time, the support frame 1 is movably connected to a rotating shaft 202 on the servo motor 2 through an active hole 101 thereon. During operation, the servo motor 2 is supported on the ground by a motor seat 201 at the bottom thereof. Then the operator can start to slide the support rollers 204 on the multiple rotating shafts 202 in the support frame 1. The operator pushes the support rollers 204 to move to the position where the cut part of the stainless steel template needs to be supported during the cutting process.

[0023] Specifically, when cutting and conveying are required, multiple servo motors 2 located on one side of the support frame 1 drive the movable plate 203 to rotate at the same speed and in the same direction. The movable plate 203 on the side of the rotating shaft 202 is arranged in the support frame 1. When the rotating shaft 202 rotates, the support roller 204 rotates with the rotating shaft 202 through the movable plate 203 on the rotating shaft 202. When the template that needs to be laser cut moves into the support frame 1, it is driven to move by the support roller 204.

[0024] Furthermore, during the cutting process, after the stainless steel template is cut by the laser cutting head 804, the cut part is supported by the support roller 204 to determine the position. After the cutting is completed, the rotating shaft 202 is driven to rotate by multiple servo motors 2, driving the support roller 204 to rotate, and outputting the cut template and the cut part of the template. In this way, during the cutting process, the cut part of the template can be well supported to prevent deformation of the cutting position caused by gravity, and it can also be well transported after cutting.

[0025] Example 2: Please refer to Figure 1 , 4, 5, 10, based on the specific embodiment 1, it also includes a pneumatic push rod 3, a moving component 4, an electric push rod 8 and a limit block 9. Three pneumatic push rods 3 are arranged on the side of the two support plates 401 away from each other, and the pneumatic push rods 3 are supported on the ground through a base 303. The piston rod 1 301 at the telescopic ends of the three pneumatic push rods 3 on the same side passes through the through hole 402 on the same support plate 401. The position of the end of the stainless steel template moving on the support roller 204 is limited by the upper limit block 9 of the push plate 302. The track 1 403 is fixedly supported on its top by the support plate 401, and the movement trajectory of the electric hoist 1 404 movably connected thereto is limited by the track 1 403. The track 2 405 fixed on its top is driven to move by the two electric hoists 1 404, and moves through the track 2 405.

[0026] Specifically, when working, the stainless steel template rotates through the rotating shaft 202 driven by the servo motor 2 in the support frame 1, driving the support roller 204 to move, so that when the stainless steel template moves into the support frame 1, the pneumatic push rod 3 is started, and the pneumatic push rod 3 drives the piston rod 301 to drive the push plate 302 to move, so that the two push plates 302 are arranged on the outside of the stainless steel template, and the distance between the two limit blocks 9 is smaller than the distance between the stainless steel templates transported in the support frame 1, so that when working, the template moves to contact the two limit blocks 9 and is limited to the end position.

[0027] Further, when the template moves to contact the two limit blocks 9, the pneumatic push rod 3 is started again, and the pneumatic push rod 3 drives the push plate 302, which drives the stainless steel template to move on the support roller 204 to fine-tune to a suitable position, and then the pneumatic push rod 3 is started to drive the piston rod 1 301 to drive the push plate 302 to move until the distance between the two limit blocks 9 is greater than the width of the stainless steel template, and the template can be cut. At this time, the moving component 4 is controlled by the C1SG model PLC, and the electric hoist 1 404 on the track 1 403 and the electric hoist 2 406 on the track 2 405 are started at the same time, so that the electric push rod 8 Move to the appropriate position above the template to be cut, complete the movement of the electric push rod 8, and then drive the piston rod 2 801 to descend through the electric push rod 8, driving the L-shaped connecting plate 802 to descend until the cutting focus of the laser cutting head 804 falls on the stainless steel template to be cut in the support frame 1, and then the C1SG model PLC can be used to control the electric hoist 1 404 and the electric hoist 2 406 to make the laser cutting head 804 move to a suitable cutting trajectory on the stainless steel template in the support frame 1, and cut the template into a suitable shape. During cutting, the template is not subjected to clamping pressure such as squeezing and stretching, and the cutting accuracy is better.

[0028] Example 3: Please refer to Figure 1 , 2, 6, 7, 8, 9, based on the specific embodiments 1 and 2, during the laser cutting of the stainless steel template, a large amount of cutting chips and cutting dust will be generated. These dust and chips are directly sprayed onto the ground of the factory below or collected in the cutting equipment during the cutting process. The operator needs to clean them carefully after the cutting is completed, which is troublesome. For this purpose, a fireproof pad 5, a servo motor 2 6 and a fixed frame 7 are provided. A fixed bar 701 is movably connected to the fixed frame 7 fixed at one end of the support frame 1, and a scraper 702 is fixed thereon through the fixed bar 701. The fixed bar 701 is telescopically The rod 703 and the compression spring 704 cooperate to make the fixed bar 701 stably movably connected and supported in the fixed frame 7. The servo motor 26 fixed at one end of the fixed frame 7 drives the driving shaft 603 to rotate, and the driving shaft 603 drives the roller 602 movably connected in the fixed frame 7 to rotate. The servo motor 26 is supported on the ground through the motor seat 2 601. When the roller 602 rotates, it drives the fireproof pad 5 movably connected in the support frame 1 to reel up. By reeling up the fireproof pad 5, the chips, dust, etc. generated by laser cutting on the surface of the fireproof pad 5 are scraped off by the scraper 702 during work.

[0029] Specifically, when the roller 602 rotates, it drives the fireproof pad 5 to reel up, and at the same time, the diameter of the roller 602 plus the fireproof pad 5 continues to increase. At this time, the fixed bar 701 is squeezed in the fixed frame 7, causing the telescopic rod 703 to contract and the compression spring 704 to be squeezed, maintaining the contact between the scraper 702 and the fireproof pad 5, thereby ensuring the squeezing force of the scraper 702 to scrape off the chips.

[0030] Furthermore, after the roller 602 completes the winding of the fireproof pad 5, the servo motor 2 6 is restarted, and the servo motor 2 6 drives the roller 602 to reverse. While the roller 602 reverses, the pull ring 502 on the pull rope 501 is pulled to pull the fireproof pad 5 back into the support frame 1. Then, by smoothing the corners of the fireproof pad 5, the chips and dust in the middle and lower parts of the laser cutting can be cleaned, so that when the stainless steel template is cut during operation, the chips and cutting dust generated during the laser cutting of the stainless steel template can be cleaned more conveniently.

[0031] Example 4: Please refer to Figure 1-11 The present invention is a stainless steel template laser cutting process, comprising the following steps: S1: During operation, first determine the shape and position of the template to be cut during work, and push the support roller 204 on the shaft 202 in the support frame 1 to ensure that the cut sheet is supported by the roller after the template is cut. When a sheet is cut, the position of the roller changes, and the roller is pushed to a suitable position again to proceed to the next step; S2: After the setting of the support roller 204 is completed, the pneumatic push rod 3 can be started immediately, and the pneumatic push rod 3 drives the piston rod 1 301 to move, and the push plate 302 is pushed toward the inner center of the support frame 1 through the piston rod 1 301, and is set outside the position where the stainless steel template needs to be cut, so that the distance between the two push plates 302 is greater than the width of the stainless steel template; S3: At the same time, the template is transported from the external transport structure to the support frame 1, and supported by the support roller 204 on the rotating shaft 202. When the servo motor 2 is driven, the template to be cut is driven to move until the template contacts the limit block 9. After the end position of the template is determined by the limit block 9, the servo motor 2 is stopped; S4: Then restart the pneumatic push rod 3 to drive the push plate 302 to move to clamp the template to be laser cut, so that the position of the template is determined in the side position in the support frame 1, and then start the pneumatic push rod 3 to drive the push plate 302 to leave the template to be cut, completing the positioning of the template; S5: After the template is positioned, laser cutting can be performed. When laser cutting is performed, the moving component 4 is controlled by the C1SG model PLC, and the electric hoist 1 404 on the track 1 403 and the electric hoist 2 406 on the track 2 405 are started at the same time, so that the electric push rod 8 moves to a suitable position on the template to be cut, so that the cutting focus of the laser cutting head 804 is set above the cutting starting point of the template; S6: After the electric push rod 8 is moved, the piston rod 2 801 is driven to descend by the electric push rod 8, driving the L-shaped connecting plate 802 to descend until the cutting focus of the laser cutting head 804 on the mounting plate 803 driven by the L-shaped connecting plate 802 falls on the stainless steel template to be cut in the support frame 1; S7: Cutting begins. During the cutting process, the C1SG PLC controls the movement of the electric hoist 1 404 and the electric hoist 2 406. The top of the optical cable 805 is connected to the external laser generator. At the same time, the optical cable 805 transmits the high-energy laser generated by the external laser generator to the laser cutting head 804, so that the laser cutting head 804 moves a suitable cutting track on the stainless steel template in the support frame 1, and cuts the template into a suitable shape. After the cutting is completed, the electric push rod 8 drives the piston rod 2 801 to rise until the laser cutting head 804 on the mounting plate 803 driven by the L-shaped connecting plate 802 rises to a suitable height. S8: After the cutting is completed, the servo motor 2 can be started to drive the rotating shaft 202 to rotate, and the supporting roller 204 can be driven to rotate, so that the stainless steel template after laser cutting and the cut template waste are transported to the next processing equipment together. When the template passes through the gap between the supporting frame 1 and the next processing equipment, the cut part of the template is separated from the template, and the template moves directly to the next processing equipment; S9: While the template is being conveyed, the next stainless steel template to be cut is aligned with the support frame 1, and the above steps of positioning and cutting the stainless steel template are repeated to complete the stainless steel template cutting cycle. During the template cutting process by the laser cutting head 804, the dust and waste generated by the cutting directly fall on the fireproof pad 5 in the support frame 1; S10: After a certain number of working cycles, the cutting operation is stopped first, and then the servo motor 2 6 is started, and the drive shaft 603 is driven to rotate by the servo motor 2 6, driving the roller 602 to rotate, and the fireproof mat 5 is driven to be wound around the roller 602 through the rotation of the roller 602; S11: When the fireproof mat 5 is wound, the scraper 702 on the fixed strip 701 in the fixed frame 7 is always pressed against the surface of the fireproof mat 5 during the winding process of the fireproof mat 5, and the dust, waste and the like on the surface of the fireproof mat 5 are scraped off and guided to the fixed frame 7 through the fixed strip 701 to be output, thereby completing the surface cleaning of the fireproof mat 5; S12: After the surface of the fireproof pad 5 is cleaned, the servo motor 2 6 is restarted to drive the roller 602 to rotate in the opposite direction, and the pull ring 502 is pulled at the same time, and the pull rope 501 and the fireproof pad 5 are pulled back into the support frame 1, and the edges and corners of the fireproof pad 5 are smoothed, and the cutting operation of the stainless steel template can be resumed.

[0032] By setting a support frame, a servo motor 1, a pneumatic push rod, a moving component, an electric push rod and a limit block, the problem that the template deformation will affect the cutting accuracy due to clamping during the laser cutting of the stainless steel template and the cutting position deformation will be easily caused without good support is solved. After the servo motor 1 drives the roller to drive the template to move to contact the two limit blocks, the pneumatic push rod is started again, and the pneumatic push rod drives the push plate to drive the stainless steel template to move on the support roller to fine-tune to a suitable position, and then the pneumatic push rod is started to drive the piston rod 1 to drive the push plate to move until the distance between the two limit blocks is greater than the width of the stainless steel template, and the template can be cut. At this time, the moving component is controlled by the C1SG model PLC, which drives the electric push rod to drive the lifting cutting head to cut, and cuts the template into a suitable shape, so that the template is not subjected to clamping pressure such as squeezing and stretching during the cutting operation, and the cutting accuracy is better. After the stainless steel template is cut by the laser cutting head, the cut part is supported by the support roller to determine the position. After the cutting is completed, the shaft is driven to rotate by multiple servo motors, driving the support roller to rotate, and the cut template and the cut part of the template are output. In this way, the cut part of the template can be well supported during the cutting process to prevent deformation of the cutting position caused by gravity, and it can also be well transported after cutting.
