A laser blanking mechanism provided with a slag removing structure

Abstract

This utility model discloses a laser feeding mechanism with a slag removal structure, relating to the field of laser slag removal technology. It includes an operating panel with two supports fixedly mounted on its top. A fixed tube is slidably connected inside the two supports, and a hollow tube is fixedly mounted at one end of each fixed tube. A dust collection head is inserted into one end of the hollow tube. A vertical plate is fixedly mounted on one side of the operating panel. The beneficial effects of this utility model are: through the arrangement of a damper, compression spring, mounting block, and sliding balls, when the circular tube is being circumferentially cut, the four sliding balls contact the inner wall of the circular tube for support. Therefore, when the circular tube rotates, the inner wall of the circular tube will not contact the dust collection head. This design prevents the rotation of the circular tube during circumferential cutting from wearing down the outer side of the dust collection head, thereby increasing its service life.

Description

Technical Field

[0001] This utility model relates to the field of laser slag removal technology, specifically a laser feeding mechanism equipped with a slag removal structure. Background Technology

[0002] During laser cutting, a high-energy-density laser beam irradiates the workpiece, causing the metal to melt and vaporize rapidly, while generating a large amount of slag. If this slag is not removed in time, it will seriously affect the cutting quality, resulting in problems such as an uneven cut surface and burrs. In addition, the slag will also adhere to the cutting head, affecting the focusing effect of the laser head, and thus affecting the cutting accuracy and speed.

[0003] A search revealed that patent number CN219900688U discloses a laser cutting mechanism with a slag removal structure, comprising a fixed frame, a hollow rod, a clamping mechanism, a laser cutting mechanism, and a tube. The hollow rod is laterally slidably mounted on the top outer surface of the fixed frame. This laser cutting mechanism with a slag removal structure, during use, utilizes the hollow tube, dust collection hole, hollow disc, hollow rod, dust collection bag, vacuum cleaner, and stretching hose. This allows the hollow tube to be inserted into one end of the tube being cut during slag removal, with the dust collection hole aligned with the bottom of the laser cutting head. This effectively collects the sparks and slag generated during cutting. After cutting, the vacuum cleaner collects and removes the slag and dust from the dust collection hole, resulting in good slag removal and reduced dust splashing.

[0004] The above-mentioned device has the following drawbacks: because several hollow tubes are fitted with different round tubes, the inner wall of the round tube will rub against the outer side of the hollow tube during circumferential cutting, which will cause wear of the hollow tube and affect the use of the device. In addition, the guide plate of the above-mentioned device is located below the hollow tube, which may cause the round tube to become congested after cutting. Therefore, we propose a laser feeding mechanism with a slag removal structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a laser feeding mechanism with a slag removal structure, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser feeding mechanism with a slag removal structure, comprising an operating plate, two supports fixedly mounted on the top of the operating plate, a fixed tube slidably connected inside the two supports, a hollow tube fixedly mounted at one end of the fixed tube, a dust collection head inserted into one end of the hollow tube, a vertical plate fixedly mounted on one side of the operating plate, a hydraulic cylinder fixedly mounted on one side of the vertical plate, the output end of the hydraulic cylinder passing through the vertical plate and fixedly connected to one end of the fixed tube, four dampers fixedly mounted on the outside of the hollow tube, mounting blocks fixedly mounted at the output ends of the four dampers, compression springs fixedly connected between the dampers and the mounting blocks, and sliding balls provided inside the four mounting blocks. A manifold box is fixedly installed at the bottom of the plate. A guide plate is fixedly installed on one side of the manifold box, and the guide plate is located below the dust collection head. A motor is fixedly installed on one side of the manifold box. A rotating shaft is rotatably connected to the inside of the manifold box. A cover plate is fixedly installed on the outside of the rotating shaft. One end of the rotating shaft passes through the manifold box and is fixedly connected to the output end of the motor. During slag removal, the damper and compression spring prevent the dust collection head from contacting the inner wall of the round tube during slag removal and limit the movement to a certain extent. Furthermore, the guide plate and manifold box ensure that the circumcised round tube falls from the guide plate into the manifold box. This process protects the dust collection head and prevents the circumcised round tube from accumulating and affecting the use of the device.

[0007] Preferably, a dust collection box is fixedly installed on one side of the vertical plate, and a drawer is slidably connected inside the dust collection box. A filter plate is fixedly installed at the bottom of the drawer. A fan is fixedly installed on one side of the dust collection box, and the fan input end extends into the dust collection box. A dust conveying pipe is fixedly connected to the outside of the hollow tube, and the other end of the dust conveying pipe passes through the vertical plate and is fixedly connected to the outside of the dust collection box. With the dust collection box, the dust can be sucked into the drawer by the operation of the fan, thereby completing the collection of dust.

[0008] Preferably, an electric push rod is fixedly installed at the top of the control panel, and an abutment plate is fixedly installed at the output end of the electric push rod.

[0009] Preferably, a limiting block is fixedly installed on the outside of the fixed tube and the hollow tube, and the limiting block is slidably connected to the bracket.

[0010] Preferably, a control panel is fixedly installed on one side of the vertical plate.

[0011] Preferably, the hydraulic cylinder, electric push rod, fan, and motor are all electrically connected to the control panel.

[0012] Preferably, the motor has a self-locking component inside.

[0013] This utility model provides a laser feeding mechanism with a slag removal structure, which has the following beneficial effects:

[0014] 1. This laser feeding mechanism with a slag removal structure uses a damper, compression spring, mounting block, and sliding ball to support the inner wall of the round tube during circumferential cutting. This prevents the inner wall of the round tube from contacting the dust collection head as it rotates. This design ensures that the rotation of the round tube during circumferential cutting does not cause wear on the outer side of the dust collection head, thus increasing its service life.

[0015] 2. The laser cutting mechanism equipped with a slag removal structure, through the setting of the manifold box and the guide plate, after the round tube is circumcised, uses an electric push rod to move the contact plate to a specified height, and then uses a hydraulic cylinder to move the fixed tube and hollow tube backward. Thus, the circumcised round tube will fall onto the guide plate through the contact plate, and then fall into the manifold box. Through this process, the cut round tube will not accumulate under the dust collection head and will not affect the use of the device. Attached Figure Description

Four dampers 7 are fixedly installed on the outside of the hollow tube 4. An installation block 9 is fixedly installed at the output end of each of the four dampers 7. A compression spring 8 is fixedly connected between the damper 7 and the mounting block 9. The damper 7 and the compression spring 8 are used to prevent the dust collection head 6 from contacting the inner wall of the round tube. Each of the four mounting blocks 9 is equipped with a sliding ball 10, which is used to facilitate the movement of the dust collection head 6. A manifold box 20 is fixedly installed at the bottom of the operating plate 1. A guide plate 21 is fixedly installed on one side of the manifold box 20. The guide plate 21 is used for the round tube to slide down, and the guide plate 21 is located below the dust collection head 6. A motor 22 is fixedly installed on one side of the manifold box 20. The motor 22 is used to drive the rotating shaft 231 to rotate. The rotating shaft 231 is rotatably connected to one side inside the manifold box 20. A cover plate 23 is fixedly installed on the outside of the rotating shaft 231. One end of the rotating shaft 231 passes through the manifold box 20 and is fixedly connected to the output end of the motor 22.

[0025] like Figure 4 As shown, a dust collection box 16 is fixedly installed on one side of the vertical plate 12. A drawer 17 is slidably connected inside the dust collection box 16. The drawer 17 is used to collect dust. A filter plate 171 is fixedly installed at the bottom of the drawer 17. A fan 19 is fixedly installed on one side of the dust collection box 16, and the input end of the fan 19 extends into the dust collection box 16. The fan 19 is used to suck up dust. A dust conveying pipe 18 is fixedly connected to the outside of the hollow pipe 4. The other end of the dust conveying pipe 18 passes through the vertical plate 12 and is fixedly connected to the outside of the dust collection box 16.

[0026] like Figure 1 As shown, an electric push rod 14 is fixedly installed at the top of the operation panel 1. The electric push rod 14 is used to move the contact plate 15. The contact plate 15 is fixedly installed at the output end of the electric push rod 14. The contact plate 15 is used to dislodge the round tube.

[0027] like Figure 1As shown, a limiting block 5 is fixedly installed on the outside of the fixed tube 3 and the hollow tube 4. The limiting block 5 is used to make the fixed tube 3 and the hollow tube 4 more stable when they move, and the limiting block 5 is slidably connected to the bracket 2.

[0030] In summary, this laser cutting mechanism with a slag removal structure is used by first placing the device on one side of the laser cutting machine. During cutting, the corresponding dust collection head 6 is replaced according to the required diameter of the round tube. The laser cutting machine clamps the round tube, and the hydraulic cylinder 13 pushes the fixed tube 3, thus moving the dust collection head 6 inside the round tube. The damper 7 and compression spring 8 ensure that the sliding ball 10 contacts the inner wall of the round tube, preventing the dust collection head 6 from directly contacting the inner wall. The dust collection head 6 is then moved below the laser cutting head, and the laser cutting machine performs a circumferential cut on the round tube. During circumferential cutting, the machine rotates the round tube, thus performing the circumferential cut. The control panel 11 activates the fan 19 (Yongqiang / CZR), thereby removing the slag from the laser tube. The slag produced during cutting first enters the dust collection head 6, and then falls sequentially from the dust conveying pipe 18 onto the drawer 17 in the dust collection box 16, thus collecting the slag. When the circumferential cutting is completed and the tube needs to be removed, the electric push rod 14 is used to move the contact plate 15 to a specified height according to the size of the round tube. Then, the hydraulic cylinder 13 is used to move the fixed tube 3, which will then contact one side of the circumferentially cut round tube and fall onto the guide plate 21, and then slide into the manifold box 20, thus preventing the round tube from accumulating. When it is necessary to remove the round tube from the manifold box 20, the control panel 11 controls the motor 22 to drive the rotating shaft 231 to rotate, which will lift the cover plate 23, and then the operator can remove the round tube. The above is the working principle of this utility model.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
