Description

Technical Field

[0001] This application relates to the technical field of laser cutting machines, and specifically relates to a laser cutting machine for heat exchange plate processing. Background Art

[0002] Laser cutting machines are widely used for cutting various materials. Laser cutting uses a high-power density laser beam to scan across the surface of the material, heating the material to several thousand to tens of thousands of degrees Celsius in an extremely short time, melting or vaporizing the material, and then blowing away the melted or vaporized substance from the cut seam to achieve the purpose of cutting the material.

[0003] For example, a laser cutting machine disclosed in Chinese Patent Publication No. (CN218503615U), which relates to the field of laser cutting, solves the problems that the current laser cutting machine has poor protection measures and the clamping of the cutting material is not good, and the protection measures are relatively poor, which is likely to cause certain harm to the operator. The technical features include: a workbench for supporting the laser cutting machine; a moving structure arranged on the lower surface of the workbench and used to move the laser cutting machine; a fixing structure arranged on the lower surface of the workbench and used to fix the laser cutting machine; a laser cutter; an adjustment structure arranged on the upper surface of the workbench and used for adjustment, which can better clamp the cutting material, and the structure is relatively simple and easy to use.

[0004] Currently, during the process of cutting raw materials, the plate needs to be placed on the loading platform of the cutting machine first, and then the laser equipment is turned on to cut the plate. The raw materials are not fixed, and for raw materials with relatively thin thickness or small size, there is a possibility of the raw materials shaking, which needs to be improved. For example, although a clamping mechanism is provided in the prior art, it is not convenient to effectively adjust according to the size of the sheet material to maintain stable cutting of the material. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, this application provides a laser cutting machine for heat exchange plate processing, which has the advantages of good adjustment and clamping effect, and solves the problem that it is not convenient to effectively adjust according to the size of the sheet material to maintain stable cutting of the material.

[0006] To achieve the above object, this application provides the following technical solution: A laser cutting machine for heat exchange plate processing, including a cutting table and a laser cutting main body arranged above the cutting table. Adjusting mechanisms are arranged on the left and right sides of the upper surface of the cutting table, and a material stabilizing mechanism is arranged on the inner wall of the adjusting mechanism;

[0007] The adjusting mechanism includes two guide rails, two sliders, two support columns, two rotating sleeves and two connecting frames. The two guide rails are fixed on the left and right sides of the upper surface of the cutting table. The two sliders are respectively slidably arranged on the outer sides of the two guide rails. The two support columns are respectively vertically fixed in the middle of the upper surfaces of the two sliders. The two rotating sleeves are respectively rotatably connected to the outer sides of the two support columns. The two connecting frames are respectively fixed to the tops of the two rotating sleeves;

[0008] The material stabilizing mechanism includes two cylinders, two fixing frames, two screw jacks, two connecting plates and four extension plates. The two cylinders are respectively fixed to the inner walls of the two connecting frames. The two fixing frames are respectively fixed to the outer sides of the output shafts of the two cylinders. The two screw jacks are respectively fixed to the inner walls of the two fixing frames. The two connecting plates are respectively fixed to the bottoms of the two screw jacks. Chutes are formed on the front, rear, left and right sides of the two connecting plates, and the four extension plates are respectively slidably connected to the interiors of the four chutes. First material stabilizing discs are respectively fixed to the middle parts of the lower surfaces of the two connecting plates. Second material stabilizing discs are respectively fixed to the lower surfaces of the four extension plates.

[0009] By adopting this technical solution, by arranging the adjusting mechanism on the left and right sides of the cutting table and arranging the material stabilizing mechanism on the inner wall, precise adjustment and stabilization can be carried out for heat exchange plates of different sizes and shapes, ensuring the accurate positioning and stability of the plates during the cutting process.

[0010] Furthermore, a controller is arranged on the outer side of the laser cutting main body, and turntables are respectively fixed to the upper surfaces of the two connecting frames.

[0011] By adopting this technical solution, the controller on the outer side of the laser cutting main body and the turntables on the upper surfaces of the connecting frames provide a more flexible operation mode and a wider application range, enabling the cutting machine to be quickly adjusted according to different cutting requirements.

[0012] Furthermore, a limiting ring is fixed to the outer side of the support column, a limiting groove is formed in the inner wall of the rotating sleeve, and the rotating sleeve is rotatably connected to the outer side of the limiting ring through the limiting groove.

[0013] By adopting this technical solution, the limiting ring on the outer side of the support column and the limiting groove in the inner wall of the rotating sleeve ensure the stability and accuracy of the rotating sleeve during rotation, avoiding errors or equipment damage caused by improper rotation.

[0014] Furthermore, a fixed ring groove is formed on the outer side of the support column and below the limiting ring, a threaded hole is formed in the outer side of the rotating sleeve, and a fixing bolt is threadedly connected to the inner wall of the threaded hole.

[0015] By adopting this technical solution, the fixed ring groove on the support column and the screw hole on the outer side of the rotating sleeve cooperate with the fixing bolt, providing a more reliable fixing method and enhancing the structural stability and durability of the equipment.

[0016] Further, the cross-sectional shape of the extension plate is T-shaped, and the sliding groove is a T-shaped groove.

[0017] By adopting this technical solution, the extension plate can slide stably in the sliding groove, adapt to plates of different widths, and improve the adaptability and flexibility of the equipment.

[0018] Further, anti-slip pads are fixed on the lower surfaces of both the first material stabilizing plate and the second material stabilizing plate, and the anti-slip pads are rubber pads.

[0019] By adopting this technical solution, the friction between the plate and the material stabilizing plate is increased, effectively preventing the plate from sliding during the cutting process and improving the cutting quality.

[0020] Further, pressure sensors are respectively fixed between the anti-slip pads and the opposite sides of the first material stabilizing plate and the second material stabilizing plate.

[0021] By adopting this technical solution, the clamping pressure of the plate can be monitored in real time to ensure the stability of the plate during the cutting process, and at the same time, damage to the plate or equipment caused by excessive pressure can be avoided.

[0022] Further, the length of the extension plate is less than the depth of the inner cavity of the sliding groove.

[0023] By adopting this technical solution, extra space is provided to adapt to plates of different thicknesses, enabling the equipment to flexibly meet different cutting requirements for different thicknesses and improving the versatility and practicality of the equipment.

[0024] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0025] For this laser cutting machine for heat exchange plate processing, through the coordinated work of the adjustment mechanism and the material stabilizing mechanism, precise adjustment and stabilization can be carried out for heat exchange plates of different sizes and thicknesses. This design allows the laser cutting machine to maintain the stability of the plate during the cutting process, reducing errors caused by the shaking or movement of the plate, thereby improving the cutting accuracy and efficiency. At the same time, by using a material stabilizing mechanism driven by a cylinder, and the design of the rotating sleeve and the support column allows for quick adjustment of the clamping angle, making the operation of the equipment more simple and fast. In addition, the use of anti-slip pads further improves the stability of the plate during the cutting process and reduces the operation risk. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting groove is formed in the inner wall of the rotating sleeve 34, and the rotating sleeve 34 is rotationally connected to the outer side of the limiting ring through the limiting groove. A fixed ring groove is formed on the outer side of the support column 33 and below the limiting ring. A threaded hole is formed in the outer side of the rotating sleeve 34, and a fixing bolt 36 is threadedly connected to the inner wall of the threaded hole. The material stabilizing mechanism 4 is fixed to the connecting frame 35 and will synchronously adjust the angle along with the rotation of the connecting frame 35 to ensure the stability of the sheet material during cutting. After the adjustment is completed, the fixing bolt 36 is tightened to insert the bolt into the ring groove to achieve angle fixation.

[0035] Please refer to Figures 3 to 4 , in order to stably clamp the sheet material for cutting, the material stabilizing mechanism 4 in this embodiment includes two cylinders 41, two fixing frames 42, two screw jacks 43, two connecting plates 44 and four extension plates 45. The two cylinders 41 are respectively fixed to the inner walls of the two connecting frames 35. The two fixing frames 42 are respectively fixed to the outer sides of the output shafts of the two cylinders 41. The two cylinders 41 are respectively fixed to the inner walls of the connecting frames 35. The fixing frames 42 are driven by the telescopic movement of the cylinders 41. The fixing frames 42 are fixed to the outer sides of the output shafts of the cylinders 41 and follow the telescopic movement of the cylinders 41. The two screw jacks 43 are respectively fixed to the inner walls of the two fixing frames 42. The two connecting plates 44 are respectively fixed to the bottoms of the two screw jacks 43. The screw jacks 43 adjust the positions of the connecting plates 44 by the lifting of the screws. Chutes are provided on the front and rear sides of the connecting plates 44 to allow the extension plates 45 to slide inside. Chutes are formed on the front and rear sides of the two connecting plates 44, and the four extension plates 45 are respectively slidably connected to the interiors of the four chutes. First material stabilizing discs 46 are respectively fixed to the middles of the lower surfaces of the two connecting plates 44. Second material stabilizing discs 47 are respectively fixed to the lower surfaces of the four extension plates 45. The extension plates 45 are respectively slidably connected to the chutes of the connecting plates 44 and can be adjusted according to the size of the sheet material. The first material stabilizing discs 46 and the second material stabilizing discs 47 are used to stabilize the sheet material.

[0036] In this embodiment, the cross-sectional shape of the extension plate 45 is T-shaped, the sliding groove is a T-shaped groove, anti-slip pads 48 are fixed to the lower surfaces of the first material stabilizing plate 46 and the second material stabilizing plate 47, and the anti-slip pads 48 are rubber pads. Pressure sensors are respectively fixed between the anti-slip pads 48 and the sides of the first material stabilizing plate 46 and the second material stabilizing plate 47 that face each other. The length of the extension plate 45 is less than the depth of the inner cavity of the sliding groove. Anti-slip pads 48 are fixed to the lower surfaces of the first material stabilizing plate 46 and the second material stabilizing plate 47, increasing the friction between the plate and the material stabilizing plate and preventing the plate from sliding. The pressure sensors can be fixed between the anti-slip pads 48 and the material stabilizing plate, used to monitor the pressure of the plate to ensure the stability of the plate.

[0037] It should be noted that the components of the screw jack 43 are as follows: The screw is usually a long rod with a helical groove, and the helical groove can be trapezoidal, rectangular or other shapes; The nut: It has an internal thread that matches the helical groove of the screw and can move linearly along the screw; The balls or rollers: Located between the screw and the nut, reducing friction and providing smooth linear motion; The bearing or support system: Ensuring the stable movement of the screw and the nut. Its principle is that when one end of the screw is rotationally driven, the helical groove starts to rotate, and the balls or rollers in the nut roll along the helical groove, which causes the nut to move axially along the screw. This axial movement of the nut provides precise linear motion and can be used to push or pull a load. When the rotation direction of the screw changes, the nut will move in the opposite direction, thus realizing the reverse movement of the load.

[0038] The working principle of the above embodiment is as follows:

[0039] (1) The operator manually slides the two sliders 32 to the appropriate positions on the left and right sides of the upper surface of the cutting table 1 according to the size of the sheet metal. Subsequently, the operator drives the connecting frame 35 and the rotating sleeve 34 to rotate along the support column 33 by rotating the turntable to adapt to the clamping angle of sheets of different sizes. The material stabilizing mechanism 4 is fixed to the connecting frame 35 and will be synchronously adjusted in angle as the connecting frame 35 rotates to ensure the stability of the sheet during cutting. After the adjustment is completed, tighten the fixing bolt 36 so that the bolt is inserted into the annular groove to achieve angle fixation.

[0040] (2) The two cylinders 41 are respectively fixed to the inner wall of the connecting frame 35. The fixed frame 42 and the screw lifter 43 are driven by the telescopic movement of the cylinders 41. The fixed frame 42 is fixed to the outside of the output shaft of the cylinder 41 and follows the telescopic movement of the cylinder 41. The screw lifter 43 adjusts the position of the connecting plate 44 through the lifting of the screw. Sliding grooves are provided on the front and rear sides of the connecting plate 44 to allow the extension plate 45 to slide inside. The extension plates 45 are respectively slidably connected to the sliding grooves of the connecting plate 44 and can be adjusted according to the size of the plate. The first material stabilizing plate 46 and the second material stabilizing plate 47 are used to stabilize the plate. Anti-slip pads 48 are fixed to the lower surfaces of the first material stabilizing plate 46 and the second material stabilizing plate 47 to increase the friction between the plate and the material stabilizing plate and prevent the plate from sliding. The pressure sensor can be fixed between the anti-slip pad 48 and the material stabilizing plate to monitor the pressure of the plate and ensure the stability of the plate.
