Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, specifically a metal sheet metal cutting device. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. We rely on sheet metal parts everywhere in our lives. They are lightweight, high-strength, conductive, and can be used for electromagnetic shielding. They also have good performance for large-scale mass production. They are widely used in electronics, communications, automotive, medical devices and other fields. Metal sheet metal cutting equipment is used to cut and process metal sheet metal materials. Through various cutting techniques, sheet metal parts are processed into the required shapes and sizes.

[0003] A search revealed a Chinese patent document disclosing a sheet metal processing and cutting device (publication number: CN222371053U). This device features a dust absorption and treatment mechanism installed on one side of the upper end of its worktable, a sheet metal clamping mechanism positioned at the center of the upper end of the worktable, a second motor at the side corner of the worktable, a lead screw installed at the output end of the second motor, a nut block connected to the threaded surface of the lead screw, a support column at the upper end of the nut block, and a T-shaped top plate at the upper end of the support column. The sheet metal clamping mechanism allows for clamping of sheet metal parts of varying sizes. A guide rod is also provided inside the side of the slider, which improves the stability of the clamping assembly during sliding to some extent. However, it still has several shortcomings:

[0004] This type of cutting device uses an electric cutting tool, which generates a lot of dust during cutting. It also requires a dust control structure, increasing the cost of subsequent maintenance and upkeep. Although the structure is relatively simple, its function is relatively limited. Its position adjustment has low freedom, making it difficult to meet the cutting needs of some high-precision and complex shapes. It may require repeated adjustments or fail to achieve high cutting accuracy, thus limiting its applicability and affecting cutting speed and quality. Furthermore, its lead screw drives one end of the T-shaped top plate to control the cutting tool to cut the sheet metal, resulting in poor stability. The vibration generated during cutting can also easily affect the cutting accuracy of the sheet metal. When fixing the sheet metal, it is necessary to clamp it in the clamping structures on both sides, which is inconvenient and cumbersome to operate, resulting in poor practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a metal sheet metal cutting device to solve the problems mentioned in the background art. Existing cutting devices use electric cutting tools, which generate a lot of dust during cutting and require a dust treatment structure, increasing the cost of subsequent maintenance and care. The structure is relatively simple but the function is relatively limited. The degree of freedom of position adjustment is low, making it difficult to meet the cutting requirements of some high-precision and complex shapes. Repeated adjustments may be required or high cutting accuracy may not be achieved. The applicable range is small, affecting the cutting speed and quality. In addition, the screw drives one end of the T-shaped top plate to control the cutting tool to cut the sheet metal, which has poor stability. The vibration generated during cutting can easily affect the cutting accuracy of the sheet metal. When fixing the sheet metal, it is necessary to clamp it in the clamping structure on both sides, which is inconvenient and cumbersome to operate and has poor practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal sheet metal cutting device, comprising a cutting worktable and a cutting device base. Slide grooves are provided at both ends of the surface of the cutting worktable. Two electric telescopic rods are fixedly installed in the middle of the inner surfaces of the two slide grooves. A slider is fixedly connected to the output end of each electric telescopic rod. A pressing structure is fixedly installed at the top of each slider. A front-rear-end moving structure is provided between the cutting worktable and the cutting device base. Moving plates are fixedly connected to both sides of the top of the front-rear-end moving structure. A left-right moving structure is provided between the two moving plates. An upper-lower moving structure is provided on one side of the left-right moving structure. A laser structure is fixedly connected to one side of the upper-lower moving structure.

[0007] Preferably, the clamping structure includes two mounting plates. A limiting plate is fixedly connected to one side of each mounting plate, and an active downward pressure plate is rotatably connected to the other side of each mounting plate. A transmission block is rotatably connected between the two active downward pressure plates at their center. A limiting block is fixedly provided on one side of the transmission block. An extension block is fixedly connected to the end of the transmission block away from the active downward pressure plate. One end of the extension block is fixedly connected to the top of the space between the two mounting plates, and a screw block is fixedly provided at the other end of the extension block. A clamping block is fixedly connected to the bottom end of the screw block. The components are combined together through a reasonable connection method to form a compact clamping structure. This structural design makes the fixing process more efficient. The components cooperate with each other and work together to enhance the stability and reliability of the entire clamping structure. Furthermore, by rotating the active downward pressure plate until it is vertical, several damping components on the clamping structure come into play, tightly abutting the clamping block against the surface of the sheet metal part. This allows for adaptation to different shaped sheet metal parts, thereby achieving effective fixing of sheet metal parts of different shapes.

[0008] Preferably, the front and rear moving structure includes a first motor, the output end of which is fixedly connected to a first central lead screw. First sliding rods are provided on both sides of the first central lead screw. First fixing blocks are provided on the surfaces of the first central lead screw and the first sliding rods. A base plate is fixedly connected to the bottom end of each fixing block. Fixing plates are fixedly connected to both ends of the base plate. One side of the fixing plate is fixedly connected to one side of the moving plate. This design of the front and rear moving structure allows the connected moving plate to move flexibly in the front-back direction, driving the left-right and upper-lower moving structures to move in the front-back direction, thereby meeting the needs of cutting sheet metal parts of different positions and shapes and expanding the applicability of the cutting device.

[0009] Preferably, the left and right moving structure includes a second motor, the output end of which is fixedly connected to a second central lead screw. A second sliding rod is provided on both sides of the second central lead screw, and a second fixing block is provided on the surface of both the second central lead screw and the second sliding rod. An I-beam is fixedly connected to one side of the second fixing block. This design of the left and right moving structure allows the connected upper and lower moving structures and laser structure to move flexibly in the left and right directions, thereby meeting the needs of cutting sheet metal parts of different positions and shapes, expanding the applicability of the cutting device. One side of the I-beam supports the upper and lower moving structures, possessing high structural strength and load-bearing capacity. It not only provides stable support for the connected upper and lower moving structures and laser structure but also ensures the reliability of the structure under different working conditions, helping to extend the service life of the entire cutting device.

[0010] Preferably, the upper and lower moving structure includes a third motor, the output end of which is fixedly connected to a third central lead screw, and third sliding rods are provided on both sides of the third central lead screw. The surfaces of the third central lead screw and the third sliding rods are provided with third fixing blocks. This allows for precise control of the laser structure's position in the vertical direction, meeting the cutting requirements of sheet metal parts of different thicknesses, and enabling precise adjustment of the laser cutter height during the cutting process, which helps improve cutting accuracy.

[0011] Preferably, the laser structure includes a lifting plate, with one top end of the lifting plate fixedly connected to one side of a third fixing block, and two fastening blocks fixedly connected to the bottom end of the other side of the lifting plate. The inner surface of the fastening blocks is provided with a laser cutter. By connecting to the third fixing block, the lifting plate can accurately rise and fall under the action of the upper and lower moving structures, thereby precisely controlling the position of the laser cutter in the vertical direction to meet the requirements of different cutting depths. At the same time, the two fastening blocks stably fix the laser cutter on the lifting plate, ensuring that the laser cutter will not shake or shift during operation, which helps to improve the cutting accuracy and quality.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This sheet metal cutting device uses laser cutting, which produces less dust and does not require a complex fume treatment structure like electric cutting tools, thus reducing the cost of subsequent maintenance and care, and reducing the overall investment and operating costs of the equipment.

[0014] The system is equipped with front and rear end moving structures, left and right end moving structures, and upper and lower end moving structures. Through the first, second, and third central lead screws, the laser structure can move flexibly in three-dimensional space, which can better meet the cutting requirements of high precision and complex shapes. It can effectively improve cutting accuracy without repeated adjustments, expand the scope of application, and the laser cutting itself has high precision and stability. It can accurately control the position and path of the laser tool, further improving the cutting quality. It can also achieve high-quality cutting for complex-shaped sheet metal parts.

[0015] The device features a simple sheet metal clamping structure. The electric telescopic rod controls the extension range of the clamping structure, which can adapt to sheet metal parts of different sizes and shapes to a certain extent. The design of multiple clamping structures can stably clamp the four corners of the sheet metal parts, which can better resist the vibration generated during cutting, reduce the impact of vibration on the cutting accuracy of sheet metal parts, improve the stability and cutting accuracy of the cutting process, and enhance the practicality of the device.

[0032] In use, the third fixing block 29 drives the lifting plate 30 to move in the vertical direction, thereby adjusting the height of the laser cutter 32 so that it can adapt to the cutting needs of sheet metal parts of different thicknesses.

[0033] In this embodiment, the sheet metal part is first placed on the cutting worktable 1.
