Description

Technical Field

[0001] This invention relates to the field of steel cutting machinery technology, specifically to an adjustable speed disc beveling device. Background Technology

[0002] The steel structure processing and production workshop has a wide variety of components, and the welding requirements for different parts of different components are different. In order to ensure that the full penetration or partial penetration standard required by the design is met, the plate must be beveled to ensure that the weld standard required by the design is met.

[0003] Currently, the main method for beveling in processing workshops is to use semi-automatic flame cutting machines. However, normal semi-automatic flame cutting machines can only move in a straight line to bevele straight strips. For circular beveling, manual cutting is used. However, manual beveling is inefficient, the beveling appearance is not aesthetically pleasing, and the beveling angle cannot be controlled. Therefore, this "adjustable speed disc beveling device" technical concept was developed. Summary of the Invention

[0004] To address the defects and problems existing in the current disc beveling process, this invention provides an adjustable-speed disc beveling device. This device has a unique structure and is easy to use, enabling fast and efficient beveling of discs. The entire process does not require manual handling, and the beveling angle remains consistent. While freeing up manpower, it ensures the consistency of the beveling product, thus effectively solving the problems of low efficiency and uneven quality in the existing disc beveling process.

[0005] The solution adopted by this invention to solve its technical problem is: an adjustable speed disc beveling device, including a support and a horizontal fixed plate, wherein the horizontal fixed plate is separately disposed on one side of the support, and a semi-automatic flame cutting machine is disposed on the upper surface of the support. The semi-automatic flame cutting machine includes a base, a torch head, and a movable torch head frame, the movable torch head frame connecting the torch head to the base, and the movable torch head frame allowing the torch head to be adjusted to different angles. The torch head is positioned towards the horizontal fixed plate, and an adjustable speed motor is disposed on the upper surface of the horizontal fixed plate. A vertical support tube is fixedly installed at the output end of the adjustable speed motor, and the top end of the vertical support tube... A rotating storage tray is fixedly installed. A quick centering and placement mechanism is movably fitted on the vertical support tube between the rotating storage tray and the adjustable speed motor. The quick centering and placement mechanism includes a positioning frame barrel, positioning corner plates, a spring-loaded part, and a stabilizing plate. A positioning hole is opened in the middle of the stabilizing plate, and the diameter of the positioning hole is larger than the diameter of the rotating storage tray. The top end of the spring-loaded part is fixedly installed with the stabilizing plate, and the bottom end of the spring-loaded part is fixedly installed with the bottom plate of the positioning frame barrel. There are multiple positioning corner plates, which are fixedly installed on the inner side wall of the positioning frame barrel in a circumferential array. The stabilizing plate has punch holes for the positioning corner plates to pass through.

[0006] Preferably, the movable gun head frame includes a fixed crossbar, a steering adjustment sleeve, and a fixed vertical bar. The fixed crossbar is fixedly installed to the base, and the fixed crossbar and the fixed vertical bar are vertically installed through the steering adjustment sleeve.

[0007] Preferably, the steering adjustment sleeve is cross-shaped and can be positioned at any angle.

[0008] Preferably, the semi-automatic flame cutting machine can move in position on the support via the wheels at its bottom.

[0009] Preferably, the spring with a smaller elastic coefficient in the rebound part has an inner diameter slightly larger than the diameter of the positioning hole.

[0010] Preferably, a guide sleeve is provided at the bottom of the positioning frame barrel, and the guide sleeve is movably fitted onto the outer surface of the vertical support tube.

[0011] The beneficial effects of this invention are as follows: Firstly, during use, the disc is placed on the rotating platform, and the positioning frame is lifted. The stabilizing plate contacts the disc during this lifting process, gradually compressing the spring-loaded portion. However, the spring-loaded portion has a low elastic coefficient and cannot support the disc when fully compressed. During this process, as the positioning frame is gradually lifted, the positioning angle plates gradually rise and contact the disc. After all the positioning angle plates have contacted the disc, the disc and the rotating platform are concentrically positioned. The semi-automatic flame cutter and the adjustable-speed motor are then turned on, and the semi-automatic flame cutter operates simultaneously with the rotating platform driving the disc to rotate. The flame cutting machine beveles the edge of the disc. The beveling is completed when the rotating tray rotates the disc one revolution. During the entire processing, only manual placement of the disc on the rotating tray is required. The beveling process does not require manual handling, freeing up manpower and avoiding the problem of unstable beveling quality due to fatigue after long hours of work. This achieves simultaneous improvement in quality and quantity. The positioning angle plate ensures that the distance between the disc edge and the torch head remains consistent during the beveling rotation, improving the disc placement speed. At the same time, compared with manual placement, it improves the processing accuracy and ensures the stability of the beveling quality.

[0012] Secondly, during use, the coordinated arrangement of the steering adjustment sleeve, fixed crossbar, and fixed vertical bar allows the gun head to be adjusted to different angles and positions. When facing discs of different thicknesses and diameters, it can be adjusted to the appropriate angle according to actual needs. At the same time, the adjustable speed motor can adjust the corresponding speed according to the size of the disc during operation, which improves the applicability of the device and makes it more suitable for market promotion.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0017] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An adjustable speed disc beveling device includes a support 1 and a horizontal fixing plate 3. The horizontal fixing plate 3 is separately disposed on one side of the support 1. A semi-automatic flame cutting machine 2 is mounted on the upper surface of the support 1. The semi-automatic flame cutting machine 2 includes a base 21, a nozzle 22, and a movable nozzle holder 23. The movable nozzle holder 23 connects the nozzle 22 to the base 21 and allows the nozzle 22 to be adjusted to different angles. The nozzle 22 faces the horizontal fixing plate 3. An adjustable speed motor 4 is mounted on the upper surface of the horizontal fixing plate 3. A vertical support tube 5 is fixedly installed at the output end of the adjustable speed motor 4, and a rotating device is fixedly installed at the top end of the vertical support tube 5. The rotating storage tray 6 and the adjustable speed motor 4 are connected by a vertical support tube 5 with a quick centering and placement mechanism 7. The quick centering and placement mechanism 7 includes a positioning frame barrel 71, a positioning angle plate 72, a spring-loaded part 73 and a stabilizing plate 74. The stabilizing plate 74 has a positioning hole 75 in the middle, and the diameter of the positioning hole 75 is larger than the diameter of the rotating storage tray 6. The top end of the spring-loaded part 73 is fixedly installed with the stabilizing plate 74, and the bottom end of the spring-loaded part 73 is fixedly installed with the bottom plate of the positioning frame barrel 71. There are multiple positioning angle plates 72, which are fixedly installed on the inner side wall of the positioning frame barrel 71 in a circumferential array. The stabilizing plate 74 has punch holes 76 for the positioning angle plates 72 to pass through. The semi-automatic flame cutting machine 2 can move its position on the support 1 via the rotating wheel at its bottom; The bottom of the positioning frame barrel 71 is provided with a guide sleeve 77, which is movably fitted on the outer surface of the vertical support tube 5. The diameter of the guide sleeve 77 is larger than the outer diameter of the vertical support tube 5 and is in contact with the outer surface of the vertical support tube 5, so as to ensure that the positioning frame barrel 71 remains concentric with the vertical support tube 5 during the up and down movement. Upon starting work, the steering adjustment sleeve 25 is first adjusted according to the specifications of the processing disc to achieve the required angle between the gun head 22 and the disc to be processed. The entire adjustment process is performed hydraulically. Hydraulic switch A is connected to hydraulic cylinder B, which in turn controls the hydraulic push rod B1. The extension or retraction of hydraulic push rod B1 adjusts the position and angle of the steering adjustment sleeve 25 accordingly. 1. First, press the hydraulic switch A1. A1 pushes the lower pressure plate A2 inside the hydraulic switch A to move downward. The lower pressure plate A2 has a liquid passage hole A3 in the middle. When the lower pressure plate A2 is pressed down to a certain distance, the connecting pipe C, which connects the hydraulic switch A and the hydraulic cylinder B, forms a passage inside the hydraulic switch A. 2. Adjust the hydraulic push rod B1 to the required length. After the hydraulic push rod B1 is adjusted to the correct position, the position and angle of the gun head 22 will meet the machining requirements. 3. After the hydraulic push rod B1 is adjusted to the correct position, release the hydraulic switch A1. Under the push of the spring A4, the lower pressure plate A2 drives the hydraulic switch A1 to rise. After the spring A4 returns to the correct position, the lower pressure plate A2 seals the connection hole between the connecting pipe C and the hydraulic switch A. At this time, the connection between the hydraulic switch A and the hydraulic cylinder B is interrupted, the hydraulic oil no longer flows, and the extension length of the hydraulic push rod B1 is fixed, so the position and angle of the gun head 22 are adjusted to the correct position. In use, place the disc on the rotating tray 6, lift the positioning frame 71, and the stabilizing plate 74 contacts the disc during the lifting process. As the stabilizing plate 74 contacts the disc, the springback part 74 is gradually compressed. However, the springback part 74 has a low elastic coefficient and cannot support the disc when fully compressed. During this process, as the positioning frame 71 is gradually lifted, the positioning angle plate 72 gradually rises and contacts the disc. After all the positioning angle plates 72 are in contact with the disc, the disc and the rotating tray 6 are concentrically positioned. Turn on the semi-automatic flame cutter 2 and the adjustable speed motor 4. Simultaneously, the rotating tray 6 drives the disc to rotate while the semi-automatic flame cutter 2... The automatic flame cutting machine 2 beveles the edge of the disc. The beveling is completed when the rotating tray 6 drives the disc to rotate one revolution. During the entire processing, only manual placement of the disc on the rotating tray 6 is required. The beveling process does not require manual handling, which frees up manpower and avoids the problem of unstable beveling quality due to fatigue after long-term work. This achieves simultaneous improvement in quality and quantity. The positioning angle plate 72 ensures that the distance between the edge of the disc and the gun head 22 remains consistent during the beveling rotation, which improves the placement speed of the disc. At the same time, compared with the manual placement method, it improves the processing accuracy and ensures the stability of the beveling quality.

[0018] Example 2: Please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 Based on embodiment 1, the movable gun head frame 23 includes a fixed crossbar 24, a steering adjustment sleeve 25 and a fixed vertical bar 26. The fixed crossbar 24 is fixedly installed on the base 21, and the fixed crossbar 24 and the fixed vertical bar 26 are vertically installed through the steering adjustment sleeve 25. The steering adjustment sleeve 25 is cross-shaped and can be positioned at any angle. As an existing technology, the steering adjustment sleeve 25 can be fixed by bolts or other means. The technology is mature and stable, so we will not go into too much detail here.

[0019] In use, the coordinated arrangement of the steering adjustment sleeve 25, the fixed crossbar 24 and the fixed vertical bar 26 allows the gun head 22 to be adjusted to different angles and positions. When facing discs of different thicknesses and diameters, it can be adjusted to a suitable angle according to actual needs. At the same time, the adjustable speed motor 4 can adjust the corresponding speed according to the size of the disc during operation, which improves the applicability of the device and makes it more suitable for market promotion.

[0020] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
