Description

Technical Field

[0001] This utility model relates to the field of flame cutting guns, and more particularly to a multi-gun flame cutting device. Background Technology

[0002] The main function of a flame cutting torch is to mix combustible gas and oxygen inside the torch to form a preheated flame with a certain thermal energy and shape. High-pressure oxygen is then ejected from the center of this preheated flame to perform the gas cutting operation. With increasing cutting demands, especially for pipe components, to improve cutting efficiency, the traditional single-torch flame cutting method is transformed into a multi-torch flame cutting method. This effectively improves cutting efficiency, as shown in the three-torch flame cutting device disclosed on the China Patent Network (publication announcement number CN215034340U). This type of flame cutting device integrates a fixed ring, a rotating ring, and three sets of flame cutting torches, and utilizes a cutting torch feed mechanism to advance and calibrate the three sets of flame cutting torches, effectively improving the axial and circumferential positioning accuracy of circumferential flame cutting and increasing processing efficiency.

[0003] However, the aforementioned disclosed patents and existing multi-gun flame cutting devices in the market still have some shortcomings: Existing methods using independent propulsion mechanisms to sequentially advance and position the flame cutting guns are prone to directional deviations due to the independent advancement and positioning of the flame cutting guns, resulting in poor accuracy for coordinated positioning of multiple flame cutting guns. Therefore, those skilled in the art have provided a multi-gun flame cutting device to solve the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-gun flame cutting device, which solves the problem of poor positioning and adjustment accuracy of existing multi-gun flame cutting devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-gun flame cutting device, comprising an integrally connected fixing frame and fixing base;

[0006] The bracket of the fixed frame is connected through a rotating ring in the middle, and the upper end of the bracket of the fixed frame is provided with a rotating electric push rod that drives the rotating ring.

[0007] The front end of the sleeve of the rotating ring is provided with a clamping fixture, and the slide of the clamping fixture is arranged in a circumferential manner with multiple sets of flame cutting guns.

[0008] The clamping fixture includes a fixture housing, inside which a track disk is rotatably connected. The guide rail of the track disk is circumferentially slidably connected to multiple sets of track slides that are one-to-one with the flame cutting gun. A drive motor for driving the track disk is provided on one side of the fixture housing.

[0009] As a further technical solution of this utility model: the back plate of the track disk is provided with a transmission worm gear, and the output end of the transmission motor is provided with a transmission worm that meshes with the transmission worm gear.

[0010] As a further technical solution of this utility model: the track disk has a spiral structure, and multiple sets of track slides are arranged in a ring symmetrical arrangement relative to the center of the track disk.

A transmission rack is provided below the frame of the guide slide table, and a transmission gear plate that meshes with the transmission rack is provided at the rear end of the sleeve of the rotating ring.

[0012] As a further technical solution of this utility model: the support back plate of the fixed frame is provided with multiple sets of clamping electric push rods arranged circumferentially along the rotating ring, and each set of clamping electric push rods is provided with a clamping pressure head at its telescopic end.

[0013] As a further technical solution of this utility model: the clamping surface of the clamping head is a V-shaped flared structure, and friction teeth are provided on the clamping surface of the clamping head.

[0014] This utility model provides a multi-gun flame cutting device, which has the following advantages compared with the prior art:

[0015] This multi-gun flame cutting device is designed based on an integrated linkage propulsion and braking system of a clamping fixture. This system drives multiple flame cutting guns in a facing configuration, with integrated linkage adjustment and positioning to synchronously adjust the cutting orientation of the multiple flame cutting guns, ensuring the accuracy of the cutting orientation. Then, based on the combination of circumferentially arranged clamping electric push rods and clamping pressure heads, the pipe to be cut is positioned.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a multi-gun flame cutting device: A multi-gun flame cutting device includes an integrally connected fixed frame 1 and a fixed base 2. A rotating ring 6 is connected through the middle of the support of the fixed frame 1. A clamping fixture 7 is provided at the front end of the sleeve of the rotating ring 6. The sliding table of the clamping fixture 7 is arranged in a circumferential manner with multiple sets of flame cutting guns 8. The clamping fixture 7 includes a fixture shell 71. A track disk 75 is rotatably connected inside the shell of the fixture shell 71. The guide rail of the track disk 75 is circumferentially slidably connected to... The flame cutting torch 8 has multiple sets of track slides 76 facing each other. A drive motor 74 for driving the track disk 75 is set on one side of the tool housing 71. A drive worm gear 72 is set on the back plate of the track disk 75. A drive worm 73 that meshes with the drive worm gear 72 is set at the output end of the drive motor 74. By controlling the operation of the drive motor 74, the drive worm 73 is driven to rotate. The meshing transmission between the drive worm 73 and the drive worm gear 72 drives the track disk 75 to rotate. As a drive source, the multiple sets of track slides 76 are driven to move in opposite directions.

[0023] The track disk 75 has a spiral structure, and multiple sets of track slides 76 are arranged symmetrically in a ring relative to the center of the track disk 75. When the track disk 75 rotates, it uses its spiral structure to convert the rotational thrust into the opposing thrust, which drives the multiple sets of track slides 76 on its track to move in opposite directions in an integrated manner. This allows for the synchronous adjustment and alignment of the cutting positions of the multiple flame cutting guns 8 to ensure the accuracy of the cutting position.

[0024] The support back plate of the fixed frame 1 is provided with multiple sets of clamping electric push rods 9 arranged circumferentially along the rotating ring 6, and each set of clamping electric push rods 9 is provided with clamping pressure head 10 at the telescopic end. The clamping surface of the clamping pressure head 10 is a V-shaped flared structure and is provided with friction teeth. By controlling the telescopic braking of multiple sets of clamping electric push rods 9, the clamping pressure head 10 at the corresponding telescopic end is pushed to move in opposite directions, so as to perform circumferential clamping and fixing of the pipe to be cut, so as to ensure cutting stability.

[0025] The upper end of the support of the fixed frame 1 is provided with a rotating electric push rod 3 that drives the rotating ring 6. The upper end of the support of the fixed frame 1 is provided with a guide rail 5 along the extension and retraction direction of the rotating electric push rod 3. The guide rail 5 is slidably connected to a guide slide 4 connected to the rotating electric push rod 3. A transmission rack 11 is provided below the frame of the guide slide 4. The rear end of the sleeve of the rotating ring 6 is provided with a transmission gear 12 that meshes with the transmission rack 11. By controlling the extension and retraction braking of the rotating electric push rod 3, the guide slide 4 is pushed to slide along the guide rail 5, which in turn pushes the transmission rack 11 to slide. By using the meshing transmission of the transmission rack 11 and the transmission gear 12, the horizontal thrust is converted into rotational thrust, which pushes the rotating ring 6 to rotate, and then pushes the combination of the clamping fixture 7 and the flame cutting gun 8 to rotate, so as to perform circumferential cutting work on the pipe inside the rotating ring 6.

[0026] The working principle of this utility model is as follows: When using a multi-gun flame cutting device for the cutting process, the cutting position of the flame cutting gun 8 is adjusted and calibrated in advance according to the size of the pipe to be cut. Then, during the adjustment process, the transmission motor 74 in the clamping fixture 7 is controlled to work, driving the transmission worm 73 to rotate. The meshing transmission of the transmission worm 73 and the transmission worm wheel 72 drives the track disk 75 to rotate. Then, the spiral structure on the track disk 75 converts the rotational thrust into the opposing thrust, pushing the multiple sets of track slides 76 on the track to move in opposite directions in an integrated linkage. The cutting position of the multiple sets of flame cutting guns 8 is adjusted and calibrated synchronously to maintain a suitable opposing direction for the precise cutting process of the pipe.

[0027] The pipe to be cut is then moved through the rotating ring 6 and controlled to extend and retract, thereby pushing the corresponding clamping heads 10 at the extension ends to move in opposite directions. This clamps the pipe to be cut in a circumferential manner. Then, the rotating electric push rod 3 is controlled to extend and retract, pushing the guide slide 4 to slide along the guide rail 5. This, in turn, pushes the transmission rack 11 to slide. By using the meshing transmission rack 11 and transmission gear 12, the horizontal thrust is converted into rotational thrust, which drives the rotating ring 6 to rotate. At the same time, it drives the combination of the clamping fixture 7 and the flame cutting gun 8 to rotate, thus performing circumferential cutting on the pipe inside the rotating ring 6. This process is faster and more accurate.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
