Description
Technical Field
[0001] This utility model relates to a double-sided bevel cutting device for steel plates, belonging to the field of flame cutting technology. Background Technology
[0002] Beveling of steel plates is typically performed using a semi-automatic flame cutting carriage. A typical flame cutting carriage has only one cutting torch and one set of piping, allowing for individual beveling of either the top or bottom of the steel plate. If beveling is required on both sides of the steel plate, the cutting carriage must perform separate beveling operations on both sides, resulting in low efficiency and long cutting time. This cutting device is specifically designed to achieve one-time beveling of double-sided steel plates. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to address the defect of existing semi-automatic cutting carriages that require two separate cuts when cutting double-sided bevels, and to provide a steel plate double-sided bevel cutting device to improve cutting efficiency.
[0004] To solve this technical problem, this utility model provides a steel plate double-sided beveling cutting device, including a horizontal support arm, a clamping connector one, a clamping connector two, an end pipe splitter, a cutting torch, and a main support arm of the cutting carriage. The horizontal support arm is cylindrical and horizontally fixed on the main support arm of the cutting carriage. It has 200mm racks on both ends, front and rear sides, with a rack mover one and a rack lockr one at each rack. The upper ends of clamping connector one and clamping connector two are respectively located on the racks at the front and rear sides of the horizontal support arm. The clamping connector two has the same structure as clamping connector one and is installed on the horizontal support arm. The components, arranged in opposite directions, include a connecting rod, a cutting torch holder, and a cutting torch locker. The upper part of the connecting rod is equipped with a rack, a rack mover II, and a rack locker II. The lower end of the connecting rod is equipped with an angle adjuster. The cutting torch holder is installed at the bottom of the connecting rod via the angle adjuster. Two cutting torches are respectively positioned in the cutting torch holders at the ends of clamping connector one and clamping connector two, and are clamped and fixed by the cutting torch locker. Adjusting the rack mover II drives the cutting torch holder, thereby moving the cutting torch up and down along the clamping connector. The angle of the cutting torch is adjusted by rotating the angle adjuster.
[0005] The horizontal support arm has gear grooves and guide rail grooves on both ends. A rack is installed in the gear groove. The front 200mm of the horizontal support arm has a gear groove on the left and a guide rail groove on the right. The rear 200mm of the horizontal support arm has a guide rail groove on the left and a gear groove on the right. The gear grooves and guide rail grooves at the front and rear ends of the horizontal support arm are in opposite directions. The clamping connector one and clamping connector two are connected to the horizontal support arm through the gear groove and guide rail groove, respectively. They move in opposite directions and do not interfere with each other. The gear groove controls the left and right movement, and the guide rail groove plays a guiding role. This allows clamping connector one, clamping connector two, and the two sets of cutting torch systems to be set independently on the left and right sides of the horizontal support arm and to move and adjust horizontally independently without interfering with each other. Loosening the rack lock one and rotating the rack mover one can adjust clamping connector one and clamping connector two to a suitable position, and then locking them through the rack lock one.
[0006] The cutting torch holder includes a connecting rod and a clamping structure. The clamping structure has an opening with through holes at both ends. The cutting torch lock passes through the through holes to clamp and fix the cutting torch set in the clamping structure.
[0007] The angle adjuster includes a clamp, an angle adjustment locking knob, and a dial. The clamp has an opening, and the angle adjustment locking knob is located at the opening. One end of the clamp is fixed to the end of the connecting rod. The dial is connected to the connecting rod of the cutting torch holder. Rotating the angle adjustment locking knob allows manual adjustment of the angle adjuster to adjust the angle of the cutting torch. Tightening the angle adjustment locking knob secures the adjustment.
[0008] The second rack mover includes an adjusting screw knob and a clamping sleeve. The clamping sleeve has a slot, and three sets of ear plates are provided at both ends of the slot. The upper and lower sets of ear plates are provided with rack lockers. The adjusting screw knob passes through the middle ear plate and contacts the rack. The first rack mover has the same structure as the second rack mover. When the cutting torch needs to be adjusted up and down, loosen the second rack locker, adjust the cutting torch holder to the appropriate position, and then tighten the second rack locker. When adjusting in the horizontal direction, loosen the first rack locker, adjust the first and second clamping connectors on the horizontal support arm to the appropriate position, and then tighten the first rack mover locker.
[0009] The adjusting screw knob has a knob at one end and a helical tooth at the other end; rotating the knob enables transmission through the meshing of its helical tooth with the rack.
[0010] The terminal pipe splitter is Y-shaped, which splits the gas input from the main pipe into two independent branch pipes, and the two branch pipes are connected to two cutting torches respectively; each of the two branch pipes is equipped with a pressure regulating valve, which can adjust the flame size independently; the other end of the terminal pipe splitter is installed on the main pipe connector of the cutting torch.
[0011] Three terminal pipeline splitters are provided and installed on the cutting trolley.
[0012] Beneficial effects: This utility model can quickly cut steel plates of different thicknesses and double-sided bevels at different angles by adjusting the horizontal, vertical and angular parameters of the two clamping connectors. Compared with the traditional single-cutting gun for cutting double-sided bevels, it saves half the time and increases efficiency by 40%. The structure is relatively simple, the reliability is high, the installation is convenient, the efficiency is high, and the cost is low. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] like Figures 1-12 As shown, this utility model provides a steel plate double-sided beveling cutting device, including a horizontal support arm 1, a clamping connector 1 2, a clamping connector 2 3, an end pipe splitter 4, a cutting torch 5, and a cutting carriage main support arm 6. The horizontal support arm 1 is cylindrical and horizontally fixed on the cutting carriage main support arm 6. Its front and rear sides are respectively provided with 200mm racks, which are staggered. The racks are equipped with a rack mover 18 and a rack locker 19. The upper ends of the clamping connector 1 2 and the clamping connector 2 3 are respectively located at the front and rear racks at both ends of the horizontal support arm 1 and can move left and right along the horizontal support arm 1. The clamping connector 2 3 has the same structure as the clamping connector 1 2 and is respectively installed on the horizontal support arm 1. Arm 1 has two sides facing opposite directions and includes a connecting rod 15, a cutting torch holder 9, and a cutting torch locker 10. The upper part of the connecting rod 15 is provided with a rack, and the rack is provided with a rack mover 18 and a rack locker 19. The lower end of the connecting rod 15 is provided with an angle adjuster 11. The cutting torch holder 9 is installed at the bottom end of the connecting rod 15 through the angle adjuster 11. Two cutting torches 5 are respectively set in the cutting torch holders 9 at the ends of clamping connector 1 and clamping connector 2 and clamping connector 2, and are clamped and fixed by the cutting torch locker 10. By adjusting the rack mover 2 13, the cutting torch holder 9 is driven, which in turn drives the cutting torch 5 to move up and down along the clamping connector. The angle of the cutting torch 5 is adjusted by rotating the angle adjuster 11.
[0028] The horizontal support arm 1 has gear grooves 7 and guide rail grooves 8 on both ends. A rack is installed in the gear groove 7. The front 200mm of the horizontal support arm 1 has a gear groove 7 on the left and a guide rail groove 8 on the right. The rear 200mm of the horizontal support arm 1 has a guide rail groove 8 on the left and a gear groove 7 on the right. The gear grooves 7 and guide rail grooves 8 at the front and rear ends of the horizontal support arm 1 are in opposite directions. The clamping connector 1 2 and clamping connector 2 3 are connected to the horizontal support arm through the gear grooves 7 and guide rail grooves 8, respectively. Their movement directions are opposite and they do not interfere with each other. The gear grooves 7 control the left and right movement, and the guide rail grooves 8 provide guidance. This allows the clamping connector 1 2, clamping connector 2 3, and the two sets of cutting torch systems to be set independently on the left and right sides of the horizontal support arm 1 and to move and adjust horizontally independently without interfering with each other. Loosening the rack lock 19 and rotating the rack mover 18 can adjust the clamping connector 1 2 and clamping connector 2 3 to a suitable position and lock them with the rack lock 19.
[0029] The cutting torch holder 9 includes a connecting rod and a clamping structure. The clamping structure has an opening and through holes at both ends of the opening. The cutting torch locker 10 passes through the through holes to clamp and fix the cutting torch set on the clamping structure.
[0030] The angle adjuster 11 includes a clamp, an angle adjustment locking knob 12, and a scale. The clamp has an opening, and the angle adjustment locking knob 12 is located at the opening. One end of the clamp is fixed to the end of the connecting rod 15. The scale is connected to the connecting rod of the cutting torch holder 9. Rotating the angle adjustment locking knob 12 manually adjusts the angle adjuster 11, which can adjust the angle of the cutting torch 5. Tightening the angle adjustment locking knob 12 can fix it, thus realizing the angle adjustment of the cutting torch 5.
[0031] The second rack mover 13 includes an adjusting screw knob 16 and a clamping sleeve 17. The clamping sleeve 17 has a slot, and three sets of ear plates are provided at both ends of the slot. The upper and lower sets of ear plates are provided with rack lockers 14. The adjusting screw knob 16 passes through the middle ear plate and contacts the rack. The first rack mover 18 has the same structure as the second rack mover 13. When the cutting torch 5 needs to be adjusted up and down, loosen the rack lockers 14 on the clamping connectors 2 and 3, rotate the second rack mover 13, adjust the cutting torch holder to a suitable position, and then lock the rack lockers 14. When adjusting in the horizontal direction, loosen the rack lockers 19 and the rack mover 18, adjust the clamping connectors 2 and 3 on the horizontal support arm 1 to a suitable position, and then lock the rack mover lockers 19.
[0032] The adjusting screw knob 16 has a knob at one end and a helical tooth at the other end; when the knob is rotated, the adjusting screw knob 16 acts as the driving element, and the transmission is achieved through the meshing of its helical tooth with the rack.
[0033] The terminal pipe splitter 4 is Y-shaped, which splits the gas input from the main pipe into two independent branch pipes to achieve Y-shaped flow splitting. The two branch pipes are connected to two cutting torches 5 respectively. Each of the two branch pipes is equipped with a pressure regulating valve, which can adjust the flame size independently, so as to realize the independent control of the flame size of the two cutting torches 5. The two cutting torch systems can move horizontally and vertically, with adjustable angles and no interference between them. The cutting torch systems can be adjusted at will according to the steel plate thickness and bevel size to achieve simultaneous cutting of double-sided bevels of the steel plate and one-time cutting. The other end of the terminal pipe splitter 4 is installed on the cutting torch main pipe connector.
[0034] Three terminal pipeline splitters 4 are provided and installed on the cutting trolley.
[0035] The basis of double-sided cutting is flame cutting, which uses a gaseous flame of oxygen and propane to preheat the metal to a temperature that allows it to burn in an oxygen stream. Then, cutting oxygen (pure oxygen) is turned on to oxidize the metal into slag, which is then blown away from the cut, thus separating the metal. This invention features two sets of pipeline branch systems and cutting torches, enabling simultaneous cutting of upper and lower bevels on the same cutting machine. During double-sided cutting, the upper bevel is preheated first, with the cutting torches for the upper and lower bevels spaced approximately 150mm apart. The lower bevel does not require a second preheating and can be cut directly, achieving the simultaneous creation of both upper and lower bevels in a single cut. The front and rear ends of the horizontal support arm of this utility model are connected to clamping connector one and clamping connector two, respectively. The tail ends of clamping connector one and clamping connector two are equipped with cutting torch holders. The cutting torch holders can move up and down along the clamping connectors and can rotate at an angle. By adjusting the parameters of the two clamping connectors in the horizontal and vertical directions and the rotation angle of the cutting torch, one-time cutting and forming of steel plates of different thicknesses and double-sided bevels of different angles can be achieved. It is easy to install, has low cost, high efficiency, and high reliability.
[0036] The above-described embodiments of this utility model are merely illustrative examples and are not the only ones. All modifications within the scope of this utility model or equivalent to this utility model are encompassed by this utility model.
