Description

Technical Field

[0001] This utility model relates to the field of flame cutting machine technology, and in particular to a flame cutting machine. Background Technology

[0002] Steel support construction is a key technology in deep foundation pit support engineering. During construction, steel plates often need to be cut. Currently, due to the difficulty in controlling the cutting lines of steel plates during manual cutting operations, multiple auxiliary lines need to be engraved on the steel plates. At the same time, the cutting surface is not perpendicular, which leads to processing difficulties and the weld quality cannot be guaranteed. Therefore, we propose a flame cutting machine to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in controlling the cutting lines of steel plates during manual cutting operations, non-perpendicular cutting surfaces, resulting in processing difficulties and unreliable weld quality. Therefore, this invention proposes a flame cutting machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flame cutting machine includes a track and a flame cutting machine body that is slidably placed on the track. Both ends of the track are provided with support seats, and the support seats are rotatably connected to the track.

[0006] The support base includes a magnetic chuck and a top plate fixed to the upper end of the magnetic chuck. An angle ruler is embedded in the top plate, and the center of the end of the track is rotatably connected to the center of the angle ruler through a rotating shaft. A pointer is provided at the inner end of the track.

[0007] A sliding shaft is horizontally mounted on the main body of the flame cutting machine. A cutting frame is provided on the sliding shaft. The cutting frame includes a sliding sleeve sleeved on the sliding shaft. A placement cylinder is fixed to the bottom end of the sliding sleeve through a connecting frame. A cutting head is inserted into the placement cylinder. A support frame is provided at the lower end of the cutting head. A spring is provided between the support frame and the bottom end of the placement cylinder. A roller is provided at the bottom end of the support frame.

[0008] Preferably, a fixing plate is provided on both outer sides of the track, and a locking bolt is provided on the fixing plate. After the track is rotated, the track can be fixed by tightening the locking bolt, thereby improving the stability of the flame cutting machine body during operation.

[0009] Preferably, a screw is provided through one side of the sliding sleeve, and the screw is threadedly connected to the sliding sleeve, so that the position of the sliding sleeve can be adjusted and locked.

[0010] Preferably, the upper end of the support frame is provided with an internal threaded ring, and the lower end of the cutting head is provided with an external thread that matches the internal threaded ring. The internal threaded ring is threadedly connected to the lower end of the cutting head. By removing the support frame, the spring can be replaced, thus avoiding the factor of unstable cutting caused by spring fatigue after long-term use.

[0011] Preferably, the spring is sleeved on the cutting head, and the outer diameter of the spring is smaller than the outer diameter of the placement cylinder and the internal threaded ring, which improves the stability when the spring is compressed.

[0012] Preferably, pulleys are provided at the four corners of the bottom of the flame cutting machine body, and the distance between two pulleys at the same end is adapted to the width of the track, so as to facilitate the sliding of the flame cutting machine body on the track and prevent it from sliding off the side.

[0013] The beneficial effects of this utility model are as follows:

[0014] Compared with the existing technology, when cutting steel plates, this utility model uses an improved flame cutting machine, which can fix the support base on the steel plate. By rotating the track and observing the angle ruler to understand the rotation angle, the cutting angle of the steel plate can be controlled, avoiding the need to repeatedly draw auxiliary lines. Then, the cutting machine is pulled to make the cutting machine move in a straight line on the track, which can ensure that the cut is flat and vertical. During welding, the quality of the weld and the appearance quality can be guaranteed.

[0015] By setting rollers and springs on the cutting head, the rollers move on the steel plate during the cutting operation, thereby driving the cutting head to make slight up and down adjustments. This ensures that the distance between the cutting head and the surface of the steel plate remains unchanged when the steel plate is bent, making it easier to cut steel plates with uneven surfaces and improving the cutting quality.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. 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 scope of protection of the present utility model.

[0021] Reference Figures 1-3 A flame cutting machine includes a track 1 and a flame cutting machine body 2 that is slidably placed on the track 1. Each of the four corners of the bottom end of the flame cutting machine body 2 is provided with a pulley. The distance between two pulleys at the same end is adapted to the width of the track 1, so as to facilitate the flame cutting machine body 2 to slide on the track 1 and at the same time prevent it from sliding off the side. Each end of the track 1 is provided with a support seat 3, and the support seat 3 is rotatably connected to the track 1.

[0022] The support base 3 includes a magnetic chuck 31 and a top plate 32 fixed on the upper end of the magnetic chuck 31. An angle ruler 33 is embedded in the top plate 32. The center of the end of the track 1 is rotatably connected to the center of the angle ruler 33 through a rotating shaft. A pointer 34 is provided at the inner end of the track 1. The angle of the track 1 after rotation is known by the cooperation of the pointer 34 and the angle ruler 33. At the same time, a fixing plate 35 is provided on the outer side of both ends of the track 1. A locking bolt 36 is provided on the fixing plate 35. After the track 1 is rotated, the track 1 can be fixed by tightening the locking bolt 36, which improves the stability of the flame cutting machine body 2 during operation.

[0023] Secondly, a sliding shaft 21 is horizontally installed on the main body 2 of the flame cutting machine. A cutting frame 22 is provided on the sliding shaft 21. The cutting frame 22 includes a sliding sleeve 221 sleeved on the sliding shaft 21. A screw is provided through one side of the sliding sleeve 221. The screw is threadedly connected to the sliding sleeve 221, which can adjust and lock the position of the sliding sleeve 221. A placement cylinder 223 is fixed to the bottom end of the sliding sleeve 221 through a connecting frame 222. A cutting head 228 is inserted into the placement cylinder 223. A support frame 224 is provided at the lower end of the cutting head 228. A spring 227 is provided between the support frame 224 and the bottom end of the placement cylinder 223. A roller 226 is provided at the bottom end of the support frame 224.

[0024] Furthermore, the upper end of the support frame 224 is provided with an internal threaded ring 225, and the lower end of the cutting head 228 is provided with an external thread that matches the internal threaded ring 225. The internal threaded ring 225 is threadedly connected to the lower end of the cutting head 228. The spring 227 is sleeved on the cutting head 228, and the outer diameter of the spring 227 is smaller than the outer diameter of the placement cylinder 223 and the internal threaded ring 225, which improves the stability when the spring 227 is squeezed. By removing the support frame 224, the spring 227 can be replaced, avoiding the factor of unstable cutting caused by spring 227 fatigue after long-term use.

[0025] In this embodiment, when cutting the steel plate, the support base 3 is fixed on the steel plate (by magnetic suction cup 31). By rotating the track 1, the pointer 34 is driven to rotate. The angle on the corresponding angle ruler 33 is observed to understand the angle of rotation. The cutting angle of the steel plate can be controlled to avoid repeatedly marking auxiliary lines. After the rotation is completed, the locking bolt 36 is tightened to fix the track 1, thereby pulling the flame cutting machine body 2 so that the flame cutting machine body 2 moves in a straight line on the track 1 to cut the steel plate.

[0026] During the cutting process, the steel plate pressing roller 226 drives the support frame 224 and the cutting head 228 to press the spring 227, which in turn drives the cutting head 228 to make slight up and down adjustments to ensure that the distance between the cutting head 228 and the surface of the steel plate remains unchanged when the steel plate is bent. This facilitates the cutting of steel plates with uneven surfaces, ensures that the cut is flat and vertical, and guarantees the quality of the weld and the appearance quality during welding.
