A welding bevel flame cutting device

Abstract

This utility model relates to the technical field of flame cutting equipment, specifically to a flame cutting device for welding bevels, to solve the problem of deformation and defects in the cut surface caused by cutting deviation. The device has two large roller tracks with two small roller tracks inside, both parallel and straight. The two large rollers are respectively embedded in the two large roller tracks and are connected by a roller coupling. A flame cutting nozzle is mounted on the roller coupling, which can be connected to a gas source for flame cutting. The two small rollers are respectively embedded in the small roller tracks and are connected by a roller coupling. The roller coupling and the small roller coupling are fixedly connected by two coupling fixing rods, ensuring that the device moves linearly along the tracks during operation, reducing cutting deviation and making the cutting dimensions more accurate. This effectively reduces the extra work required for correction and rework due to uneven cutting. The device is simple to operate and can easily complete cutting work.

Description

Technical Field

[0001] This utility model relates to the field of flame cutting equipment technology, specifically to a flame cutting device for welding bevels. Background Technology

[0002] Steel, as a basic material, is used in enormous quantities and has extremely wide applications. Among them, steel plates occupy an important position in bridge construction, pressure vessels, oil and gas pipelines, marine engineering structures, and the manufacture of various engineering machinery. In the production process of steel enterprises, steel plates often need to be flame-cut into the required dimensions.

[0003] Currently, flame cutting technology has significant technical bottlenecks. If the operation is not properly controlled, the cutting surface is easily deformed and defective due to cutting deviations, which leads to frequent corrections and rework, increasing the workload. Cutting errors also cause a large amount of material waste, further increasing production costs. Utility Model Content

[0004] This invention provides a welding bevel flame cutting device to solve the problem of deformation and defects in the cut surface caused by cutting deviation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding bevel flame cutting device includes a large wheel track symmetrically fixedly arranged, and a small wheel track fixedly and parallelly arranged on the inner side of the large wheel track. A large roller is movably arranged in the large wheel track, and a small roller is movably arranged in the small wheel track. The large roller and the small roller are arranged in a synchronous displacement state, and a flame cutting nozzle is movably arranged on the shaft of the large wheel.

[0007] Furthermore, the large rollers are connected by a large roller coupling, the small rollers are connected by a small roller coupling, and the large roller coupling and the small roller coupling are symmetrically and fixedly connected by a coupling fixing rod.

[0008] Furthermore, a cutting nozzle connecting rod is horizontally threaded onto the large wheel shaft, and the flame cutting nozzle is fixedly connected to one end of the cutting nozzle connecting rod. The cutting nozzle connecting rod and the large wheel shaft are detachably connected by a nut.

[0009] Furthermore, both ends of the small wheel track and the large wheel track are fixedly equipped with frame edges.

[0010] Furthermore, the device is reasonably designed and relatively easy to operate, allowing even less experienced operators to complete the cutting work effectively.

[0011] This utility model has the following beneficial effects:

[0012] This device features two parallel, straight tracks: a large track and a small track. The two large rollers are embedded in the large track and connected by a roller coupling, which houses a flame cutting nozzle that can be connected to a gas source. The two small rollers are embedded in the small track and connected by a roller coupling. The large and small roller couplings are fixed together by two coupling rods, ensuring the device moves strictly along a straight line during operation. This significantly reduces cutting deviation, resulting in more precise cutting dimensions. The flame-cut metal cut is smooth, with consistent width, a small heat-affected zone, reduced deformation and defects, maximized material utilization, improved workpiece quality, and reduced corrections and rework. The device is simple to operate and easy to master, suitable for various metal materials and different working scenarios and needs.

[0013] In addition, the design of this cutting tool fully considers ergonomics and ease of use. It has a reasonable structure, clear and intuitive layout of each functional component, and optimized operation process that is simple and easy to learn. No complicated preparatory knowledge or long-term training is required. Even operators with little experience or limited operating skills can master the basics in a short time and complete various cutting tasks safely and efficiently, effectively reducing reliance on skilled workers.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-2 As shown, a welding bevel flame cutting device includes a large wheel track 2 symmetrically fixedly arranged, a small wheel track 1 fixedly and parallelly arranged on the inner side of the large wheel track 2, a large roller 3 movably arranged in the large wheel track 2, a small roller 4 movably arranged in the small wheel track 1, the large roller 3 and the small roller 4 are arranged in a synchronous displacement state, and a flame cutting nozzle 8 is movably arranged on the large wheel connecting shaft 6.

[0020] Large rollers 3 are connected by a large roller shaft 6, and small rollers 4 are connected by a small roller shaft 5. A shaft fixing rod 7 is symmetrically and fixedly connected between the large roller shaft 6 and the small roller shaft 5.

[0021] A cutting nozzle connecting rod 9 is horizontally threaded onto the large wheel coupling 6. A flame cutting nozzle 8 is fixedly connected to one end of the cutting nozzle connecting rod 9, and the cutting nozzle connecting rod 9 and the large wheel coupling 6 are detachably connected by a nut 10.

[0022] Both ends of the small wheel track 1 and the large wheel track 2 are fixed with a frame 11.

[0023] In practical use, the operator places the welding bevel flame cutting device on the metal surface to be cut, adjusts the flame angle of the flame cutting nozzle 8 by rotating the cutting nozzle connecting rod 9, and then fixes the flame cutting nozzle 8 to the large wheel connecting shaft 6 with the nut 10. The small wheel track 1 and the large wheel track 2 are arranged in parallel, with the large roller 3 rolling on the large wheel track 2 and the small roller 4 rolling on the small wheel track 1. The two large rollers 3 are connected by the large wheel connecting shaft 6, and the two small rollers 4 are connected by the small wheel connecting shaft 5. The connecting shaft is fixed. Rod 7 then fixes the large wheel coupling 6 and the small wheel coupling 5 together, so that the whole trolley can run stably in a straight line within the specified track. Further, the flame cutting nozzle 8 is connected to the gas source and ignited. The operator pushes the whole device, which consists of the large roller 3, the small roller 4, the small wheel coupling 5, the large wheel coupling 6, and the coupling fixing rod 7, to move on the small wheel track 1 and the large wheel track 2, ensuring that the flame cuts the metal in a straight line, thereby ensuring the flatness and straightness of the metal cut surface, reducing cutting deviation, making the cutting size more accurate, and improving the cutting quality.
