Description

Technical Field

[0001] This utility model relates to a cutting device, and more particularly to a stainless steel cutting device. Background Technology

[0002] In industrial production, stainless steel sheets are widely used in various industries such as kitchenware, medical devices, automotive parts, and building decoration due to their combination of corrosion resistance, high strength, and good machinability. As market demands for product precision and appearance quality continue to increase, laser cutting has become the mainstream method for processing stainless steel sheets due to its advantages of high cutting speed, smooth cut edges, and small heat-affected zone.

[0003] During processing, the operator moves the stainless steel sheet onto the equipment support platform and initially fixes the sheet manually or through a simple positioning mechanism; then, after inputting the cutting parameters on the control panel, the laser cutter is started, and the laser cutter cuts along the preset path with the transmission mechanism; after cutting is completed, the finished product and waste are separated manually and the support platform is cleaned.

[0004] Existing technologies can realize the basic processing flow of stainless steel sheets from positioning and cutting to finished product separation. The technological advantages of laser cutting meet the basic requirements for sheet cutting accuracy in most scenarios, providing downstream industries with processing blanks that meet size requirements and supporting the operation of basic production links. However, existing equipment only uses a support platform to place the sheet flat, lacking an effective stabilizing structure. When the sheet to be cut has slight warping, or when the laser force causes local stress on the sheet during the cutting process, the sheet is prone to displacement. When the laser cutter moves during the cutting process, the cutting path may deviate from the preset trajectory, resulting in cutting errors such as dimensional deviation and misaligned cuts. This not only increases the scrap rate, but also requires manual rework or scrapping of defective products, seriously affecting production efficiency and processing cost control. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the technical problem of this utility model is to provide a stainless steel cutting device.

[0006] The technical solution is as follows: A stainless steel cutting device includes a main body, a control panel, guide rails, a first transmission component, a slide block, a second transmission component, a slide table, an electric cylinder, a laser cutter, a support base, and a sawtooth support bar. The control panel is located on the front side of the main body. Guide rails are horizontally arranged on both the front and rear sides of the upper part of the main body. Slide blocks are slidably mounted on each guide rail. A second transmission component is located between the upper parts of two slide blocks. The first transmission component is horizontally arranged on the rear side of the upper part of the main body. The first transmission component is connected to the rear slide block, driving the rear slide block to move left and right along the guide rails, thereby causing the two slide blocks and the second transmission component to move left and right synchronously along the guide rails. A slide table is fitted onto the second transmission component, which drives the slide table to move back and forth along its length. An electric cylinder is vertically mounted on one side of the slide table, and a laser cutter is slidably mounted on one side of the electric cylinder, equipped with... The laser cutter's laser head and the vision lens of the vision module are both vertically downwards. The drive rod of the electric cylinder is fixedly connected to the laser cutter, allowing the laser cutter to move vertically up and down. The main body of the equipment has an internal cavity, with a support base at the top. Several serrated support strips are spaced horizontally on the upper part of the support base, each supporting the stainless steel sheet to be cut. The gap between two adjacent serrated support strips is connected to the cavity of the main body. A pressure plate assembly is located at the bottom of the laser cutter. When the electric cylinder drives the laser cutter downwards, the pressure plate assembly moves downwards synchronously with the laser cutter. Before the laser head cuts the stainless steel sheet, the pressure plate assembly contacts and applies pressure to the stainless steel sheet surrounding the laser head, pressing it firmly onto the serrated support strips.

[0007] Furthermore, the pressure plate assembly includes a lower pressure frame, guide blocks, sleeve rods, flexible balls, and spring 1. The lower pressure frame is provided at the lower part of the laser cutter. The lower pressure frame is arranged around the lower periphery of the laser cutter and is relatively fixed to the laser cutter. Multiple guide blocks are distributed at intervals around the lower part of the lower pressure frame. A sleeve rod is slidably arranged at the lower part of each guide block in the vertical direction. Spring 1 is provided inside each sleeve rod. The two ends of spring 1 abut against the lower part of the corresponding guide block and the inner bottom wall of the sleeve rod, respectively. Flexible balls are embedded in the lower part of each sleeve rod, and the flexible balls protrude from the lower surface of the sleeve rod.

[0008] Furthermore, it also includes guide plates, a frame, and a transmission component. A frame is arranged laterally in the lower part of the cavity of the main body of the equipment. The left end of the frame extends from the inside of the cavity of the main body of the equipment to the outside of the main body. A transmission component is arranged laterally inside the frame. The transmission component consists of two rotating shafts and a conveyor belt wrapped around the outside of the two rotating shafts. A drive motor is connected to one of the rotating shafts. The drive motor can drive the rotating shaft to rotate, thereby driving the conveyor belt to circulate. Guide plates are symmetrically arranged on the front and rear sides of the lower part of the support base. The lower part of the two guide plates extends inclinedly towards the conveyor belt of the transmission component and to the side corresponding to their own front and rear.

[0009] Furthermore, the conveyor belt of the transmission component is made of metal.

[0010] Furthermore, it also includes a mounting base, a scraper, and a second spring. The mounting base is fixedly installed on the lower left side of the frame, and the scraper is slidably installed on the mounting base. The second spring is installed below the scraper, and the two ends of the second spring are connected to the mounting base and the scraper, respectively. Under the action of the spring, the scraper maintains a state of frictional contact with the lower left side of the conveyor belt of the transmission component.

[0011] Furthermore, it also includes hard ball bearings, with multiple hard ball bearings embedded on the top left and right sides of the support base and the top left and right sides of the main body of the equipment.

[0012] Beneficial effects: 1. During laser cutting, the pressure plate assembly moves downward synchronously with the laser cutter. The flexible ball bearings on it first contact the stainless steel plate around the laser head, which can stably press the plate around the laser head onto the sawtooth support bar. This avoids cutting errors caused by the plate warping or displacement due to force during laser cutting. At the same time, when the laser cutter moves with the slide and slide table to cut, the flexible ball bearings can roll along the surface of the plate, reducing friction between the pressing structure and the plate. This not only ensures the cutting dimensional accuracy but also prevents the plate surface from being damaged by friction, thus improving the quality and stability of the cutting process.

[0013] 2. This utility model, through the setting of the guide plate and conveyor belt, can transport and discharge the small chips, slag and waste generated during cutting, eliminating the need for frequent manual cleaning, reducing the intensity of manual labor, avoiding the accumulation of waste that affects subsequent cutting operations, and improving the overall processing efficiency.

[0014] 3. This utility model has multiple hard ball bearings embedded on the left and right sides of the top of the support base and the left and right sides of the top of the main body of the equipment. During the plate placement stage, when it is necessary to place or adjust the position of the stainless steel plate to be cut, the plate comes into contact with the hard ball bearings, and the original sliding friction is transformed into rolling friction. This greatly reduces the friction force when the plate moves, making it easier for the operator to push the plate and reducing the difficulty of operation during plate placement and adjustment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] A stainless steel cutting device, such as Figure 1-5As shown, the device includes a main body 1, a control panel 2, a guide rail 3, a transmission component 1 31, a slide 4, a transmission component 2 5, a slide table 51, an electric cylinder 52, a laser cutter 53, a support base 6, and a serrated support bar 61. The main body 1 serves as the installation and support foundation for the entire device. The control panel 2 is located on its front side. The control panel 2 is electrically connected to the transmission component 1 31, transmission component 2 5, electric cylinder 52, laser cutter 53, and vision module inside the device. The operator can input cutting parameters (such as cutting path, laser power, and moving speed) through the control panel 2 and send control commands to drive the various components to work together. The upper front and rear of the main body 1... Guide rails 3 are arranged laterally on both sides, providing guidance and constraint for the movement of the slides 4. Slides 4 are slidably mounted on each guide rail 3, and a transmission component 2 5 is fixedly connected between the upper parts of the two slides 4, so that the two slides 4 can synchronously drive the transmission component 2 5 to move along the guide rail 3. A transmission component 1 31 is arranged laterally on the upper rear side of the main body 1. The power output end of the transmission component 1 31 is connected to the rear slide 4. When the control panel 2 sends a drive command to the transmission component 1 31, the transmission component 1 31 can drive the rear slide 4 to move left and right along the guide rail 3, and then drive the transmission component 2 5 to move left and right along the guide rail 3 through the synchronous movement of the two slides 4. The transmission component 2 (5) is moved to adjust its position in the lateral direction. A slide table 51 is fitted onto the transmission component 2 (5). The transmission component 2 (5) is electrically connected to the control panel. When the control panel 2 sends a command to the transmission component 2 (5), the transmission component 2 (5) can drive the slide table 51 to move along the length (front-back direction) of the transmission component 2 (5). An electric cylinder 52 is fixedly installed vertically on one side of the slide table 51. The electric cylinder 52 is electrically connected to the control panel 2. A laser cutter 53 is slidably mounted vertically on one side of the electric cylinder 52. The laser cutter 53 is equipped with a vision module, which is electrically connected to the control panel 2. The vision module can collect image information of the surface of the material to be cut in real time and transmit it to the control panel 2. Control panel 2 provides visual assistance to laser cutter 53 by analyzing image information. During processing, it sends position adjustment commands to transmission component 31 and transmission component 5 according to the material condition to adjust the position of laser cutter 53 and ensure cutting accuracy. The laser head of laser cutter 53 and the vision lens of vision module are both set vertically downward. The drive rod of electric cylinder 52 is fixedly connected to laser cutter 53. When control panel 2 sends lifting command to electric cylinder 52, electric cylinder 52 can drive laser cutter 53 to move up and down in the vertical direction to adjust the distance between laser head and material to adapt to the cutting needs of materials of different thicknesses.The main body 1 of the equipment has an internal cavity that provides space for waste collection and transportation. A support base 6 is fixedly installed at the upper part of the cavity, providing mounting support for the serrated support bars 61. Several serrated support bars 61 are spaced laterally along the upper part of the support base 6. Each serrated support bar 61 supports the stainless steel sheet to be cut. The serrated structure reduces the contact area between the sheet and the support bar, preventing the support bar from obstructing the laser cutting path during the cutting process. The gap between two adjacent serrated support bars 61 is connected to the cavity of the main body 1, allowing... Waste generated during cutting can fall into the cavity through this gap for easy collection and processing. A pressure plate assembly is provided at the lower part of the laser cutter 53. The pressure plate assembly is relatively fixed to the laser cutter 53. When the electric cylinder 52 drives the laser cutter 53 to move downwards, the pressure plate assembly moves downwards synchronously with the laser cutter 53. Before the laser head of the laser cutter 53 contacts the stainless steel sheet to be cut, the pressure plate assembly first contacts and applies pressure to the stainless steel sheet around the laser head to press and fix it firmly onto the sawtooth support bar 61, preventing displacement of the sheet during laser cutting.

[0024] Among them, such as Figure 1 , Figure 3 and Figure 4As shown, the pressure plate assembly includes a lower pressure frame 54, guide blocks 55, sleeve rods 56, flexible balls 57, and springs 58. The lower pressure frame 54 is fixedly mounted on the lower part of the laser cutter 53. The lower pressure frame 54 surrounds the lower periphery of the laser cutter 53 and remains relatively fixed to it, ensuring that the lower pressure frame 54 can move synchronously with the laser cutter 53. Multiple guide blocks 55 are spaced apart along the lower part of the lower pressure frame 54. The guide blocks 55 are fixedly connected to the lower pressure frame 54. Each guide block 55 has a sleeve rod 56 slidably mounted vertically on its lower part. 5 provides vertical constraint for the sliding of the sleeve 56 to prevent the sleeve 56 from shifting laterally. Each sleeve 56 is provided with a spring 58 inside. The two ends of the spring 58 abut against the lower part of the corresponding guide block 55 and the inner bottom wall of the sleeve 56, respectively, so that the sleeve 56 can remain extended under the action of the spring 58 when no external force is applied. Each sleeve 56 is embedded with a flexible ball 57 at the bottom. The flexible ball 57 can roll freely at the bottom of the sleeve 56 and protrudes from the lower surface of the sleeve 56 to ensure that the flexible ball 57 can preferentially contact the plate. When the control panel 2 sends a downward movement command to the electric cylinder 52, the electric cylinder 52 drives the laser cutter 53 to move downward. Simultaneously, the lower pressure frame 54 moves downward with the laser cutter 53 until the flexible ball 57 at the bottom of the sleeve 56 contacts the surface of the stainless steel sheet to be cut. At this point, as the laser cutter 53 continues to move downward, the sleeve 56 is subjected to the reaction force of the sheet and slides upward along the guide block 55, simultaneously compressing the spring 58. The elastic force generated by the compressed spring 58 is transmitted through the sleeve 56 to the flexible ball 57, which then acts on the stainless steel sheet to cut the stainless steel around the laser head. The steel plate is stably pressed against the serrated support bar 61 to prevent the plate from shifting due to warping or laser force during laser cutting. During the laser cutting process, when the control panel 2 sends movement commands to the transmission component 31 and the transmission component 5 to drive the laser cutter 53 to move with the slide block 4 and the slide table 51, the flexible ball bearings 57 can roll along the surface of the stainless steel plate, converting the sliding friction between the lower pressure frame 54 and the plate into rolling friction. This significantly reduces the friction between the lower pressure frame 54 and the stainless steel plate, preventing scratches on the plate surface due to friction and reducing the resistance when the laser cutter 53 moves, ensuring a smooth cutting process.

[0025] First, the operator places the stainless steel sheet to be cut on the serrated support strip 61 on the upper part of the support base 6 inside the cavity of the main body 1. The serrated structure of the serrated support strip 61 reduces the contact area between the sheet and the support surface, preventing the support structure from obstructing the subsequent laser cutting path, and ensuring the sheet is placed stably through the spaced support points. Next, the operator enters the parameter setting and equipment start-up phase. The operator inputs processing parameters through the control panel 2 on the front of the main body 1, including the laser cutting path, the laser power of the laser cutter 53, and the moving speed of the transmission component 31 and the transmission component 5. Electrical connections are established between transmission component 31, transmission component 5, electric cylinder 52, laser cutter 53, and vision module. After parameter input, control panel 2 generates collaborative control commands. After the equipment is started, laser cutter 53 uses vision module to identify the position of the board. Control panel 2 immediately sends adjustment commands to transmission component 31 and transmission component 5. Transmission component 31 drives the rear slide 4 to move left and right along guide rail 3, causing the two slides 4 and transmission component 5 to adjust laterally in sync. Transmission component 5 drives slide 51 to move back and forth along its own length. Together, they drive laser cutter 53 to move to a position aligned with the area of ​​the board to be cut.

[0026] After positioning, the control panel 2 sends a downward movement command to the electric cylinder 52. The electric cylinder 52 drives the laser cutter 53 to descend vertically. At this time, the pressure plate assembly, which is relatively fixed to the laser cutter 53, descends synchronously with the laser cutter 53. Since the flexible ball 57 at the bottom of the sleeve rod 56 protrudes from the surface of the sleeve rod 56, the flexible ball 57 will contact the surface of the plate before the laser head of the laser cutter 53. As it continues to descend, the sleeve rod 56 slides upward along the guide block 55 under the reaction force of the plate and compresses the spring 58. The elastic force of the spring 58 is transmitted to the flexible ball 57 through the sleeve rod 56, pressing the plate around the laser head tightly onto the serrated support bar 61. Even if the laser generates local impact force on the plate during the cutting process, the pressed state can keep the plate stable, avoid the cutting path deviation, and ensure the cutting dimension accuracy.

[0027] While the laser cutter 53 moves along the preset path for cutting, the control panel 2 continuously sends movement commands to the first transmission component 31 and the second transmission component 5 according to the cutting path: the first transmission component 31 drives the slide 4 to move left and right along the guide rail 3, and the second transmission component 5 drives the slide 51 to move back and forth. The two work together to drive the laser cutter 53 to move precisely in the horizontal direction. At the same time, the pressure plate assembly moves synchronously with the laser cutter 53, and the flexible ball 57 at the bottom of the sleeve rod 56 rolls along the surface of the plate, converting the sliding friction between the lower pressure frame 54 and the plate into rolling friction. This not only avoids surface scratches caused by friction between the fixed pressing structure and the plate in the prior art, but also reduces the resistance when the laser cutter 53 moves, ensuring a smooth cutting process, reducing the problem of uneven cutting depth caused by resistance fluctuations, and improving the flatness of the cut and the appearance quality of the product. The stainless steel waste and molten slag generated during the cutting process will fall into the cavity of the main body 1 through the gap between the sawtooth support bars 61. After processing a plate, the operator turns off the equipment and removes the cut plate and the waste generated.

[0028] Example 2

[0029] Based on Example 1, such as Figure 3 and Figure 5 As shown, it also includes a guide plate 7, a frame 71, and a conveyor 72. The frame 71 is fixedly installed laterally in the lower part of the cavity of the main body 1, serving as the mounting support for the conveyor 72. Its left end extends from inside the cavity of the main body 1 to the outside of the main body 1. This extension structure ensures that the waste conveyed by the conveyor 72 can be directly transferred to the outside of the main body 1, preventing waste from accumulating inside the equipment. The conveyor 72 is mounted laterally inside the frame 71. The conveyor 72 consists of two rotating shafts and a conveyor belt wound around the two rotating shafts. The two rotating shafts are rotatably installed at the left and right ends inside the frame 71, respectively. A drive motor is connected to one of the rotating shafts, and the drive motor is electrically connected to the control panel 2 in Embodiment 1. When the control panel 2 is in the cutting operation... When the machine starts and sends a running command to the drive motor, the drive motor can drive the shaft connected to it to rotate, thereby driving the conveyor belt to circulate counterclockwise along the two shafts to realize the automatic conveying of waste. The front and rear sides of the lower part of the support base 6 are symmetrically fixed with guide plates 7. The connection position of the guide plates 7 and the support base 6 corresponds to the gap between the sawtooth support bars 61. The lower parts of the two guide plates 7 extend upwards towards the conveyor belt of the transmission component 72 and on the side corresponding to their front and rear. This inclined structure can guide the waste falling from the gap of the sawtooth support bars 61 to slide down the surface of the guide plates 7 and accurately collect on the conveyor belt of the transmission component 72, avoiding the waste from falling directly to the bottom of the frame 71 or the cavity of the main body 1, which would cause cleaning difficulties and improve the convenience and efficiency of waste collection.

[0030] Among them, the conveyor belt of the transmission component 72 is made of metal. Compared with ordinary rubber or plastic conveyor belts, metal has stronger high temperature resistance and wear resistance, and can withstand long-term contact and impact of laser cutting waste. It avoids the conveyor belt from deformation due to high temperature or friction damage from waste, effectively extending the service life of the transmission component 72. At the same time, the surface of the metal conveyor belt is smooth and the structure is stable, making it less likely for waste to stick to it, thus reducing the residue of waste on the conveyor belt.

[0031] like Figure 4 As shown, it also includes a mounting base 73, a scraper 74, and a second spring 75. The mounting base 73 is fixedly installed on the lower left side of the frame 71 near the lower surface of the conveyor belt. The scraper 74 is slidably mounted on the mounting base 73 in a vertical direction. The upper part of the scraper 74 corresponds to the lower left side of the conveyor belt of the transmission component 72. A second spring 75 is installed at the lower part of the scraper 74. Both ends of the second spring 75 are fixedly connected to the top of the mounting base 73 and the lower part of the scraper 74, respectively. Under the natural elastic force of the second spring 75, the scraper... The scraper 74 is lifted upwards to maintain frictional contact with the lower left side of the conveyor belt of the transmission component 72. When the conveyor belt circulates, the scraper 74 can scrape off any small waste that may be stuck to the surface of the conveyor belt, preventing the small waste from returning to the inside of the frame 71 as the conveyor belt rotates, thus ensuring that the surface of the conveyor belt is clean. At the same time, the elastic structure of the second spring 75 allows the scraper 74 to adaptively adjust its position according to the slight vibration or surface undulation of the conveyor belt, always maintaining close contact with the conveyor belt and ensuring a stable scraping effect.

[0032] In addition, such as Figure 1-3 As shown, it also includes hard balls 8. Multiple hard balls 8 are embedded on the top left and right sides of the support base 6 and the top left and right sides of the equipment body 1. The rolling surface of the hard balls 8 protrudes from the top surface of the support base 6 and the equipment body 1. During the plate placement stage, when the operator places the stainless steel plate to be cut onto the equipment, the edge of the plate contacts the hard balls 8. The original sliding friction between the plate and the support base and the equipment body is transformed into the rolling friction of the hard balls 8. This change in friction can greatly reduce the resistance when the plate moves, making it easier for the operator to push the plate to adjust its position and reducing the difficulty of loading and fine-tuning the position of the plate.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
