Description

Technical Field

[0001] The present application relates to the technical field of gas cutting auxiliary tools, and in particular to a tool for rapid gas cutting of circular steel plates. Background Art

[0002] Gas cutting, also known as flame cutting, is commonly used in steel plate processing. It mainly uses the high temperature generated by the combustion of iron oxide to cut carbon steel. The design of the flame cutting torch provides sufficient oxygen for the combustion of iron oxide to obtain better cutting results.

[0003] When using the cutting torch, the worker holds the handle and points the cutting nozzle of the cutting torch toward the steel plate to cut the steel plate. The cutting process requires the operator to master certain techniques, control the distance between the cutting nozzle and the steel plate, and move the nozzle. The cutting is prone to deviation during the process, and the worker has a heavy workload. Especially in the process of cutting round steel plates, it is more difficult for the worker to grasp the circular moving path of the nozzle, resulting in low cutting efficiency of the steel plate. Utility Model Content

[0004] In order to improve the cutting efficiency of steel plates and reduce the labor burden of workers, the present application provides a tool for quickly gas cutting circular steel plates.

[0005] The present application provides a tool for rapid gas cutting of circular steel plates using the following technical solutions:

[0006] A tool for fast gas cutting of circular steel plates comprises a positioning piece, one end of which is connected to the barrel of a cutting torch, and the other end of which extends in a direction parallel to the direction of a cutting nozzle to a side of the cutting nozzle away from the barrel.

[0007] By adopting the above technical solution, during the steel plate cutting process, the positioning piece is abutted against the steel plate and the gun barrel is parallel to the steel plate, so that the distance between the cutting nozzle and the steel plate can be controlled. At the same time, the gun barrel is rotated with the positioning piece as the center so that the cutting nozzle can move in a circular path, which makes it convenient for workers to cut circular steel plates while improving the cutting effect.

[0008] Optionally, the positioning member includes a sliding portion and a supporting portion, the sliding portion is provided with a sliding hole, the sliding portion is slidably mounted on the barrel of the cutting torch, and the supporting portion is fixedly connected to the sliding portion.

[0009] By adopting the above technical solution, the sliding part can drive the supporting part to slide, so that the distance between the positioning member and the cutting nozzle can be adjusted, and the cutting torch can cut circular steel plates of different diameters.

[0010] Optionally, a pointed cone portion is provided at one end of the supporting portion away from the sliding portion, and the tip of the pointed cone portion is away from the supporting portion.

[0011] By adopting the above technical solution, the tip of the cone portion is pressed against the steel plate, thereby reducing the contact area between the support rod and the steel plate, thereby facilitating the rotation of the cutting torch.

[0012] Optionally, a locking piece is provided on the sliding part, and the locking piece includes a threaded rod. A threaded hole communicating with the sliding hole is opened on the sliding part, and the threaded rod is threadedly connected in the threaded hole.

[0013] By adopting the above technical solution, the threaded rod is threadedly connected in the threaded hole. When the threaded rod is rotated, the threaded rod can be pressed against the gun barrel under the action of the thread, and the sliding part is limited under the action of friction, thereby improving the stability of the positioning part during steel plate cutting.

[0014] Optionally, a supporting assembly is provided on the positioning member, and the supporting assembly includes a stabilizing seat, and the stabilizing seat is slidably sleeved on the supporting portion along the length direction of the supporting portion, and the stabilizing sleeve can rotate relative to the positioning member.

[0015] By adopting the above technical solution, during the steel plate cutting process, when the pointed cone portion abuts against a specific position of the steel plate, the sliding support portion makes the support portion fit and abut against the steel plate. At this time, the stabilizing seat limits the support portion, so that the positioning piece is stably in a state perpendicular to the steel plate, thereby making the cutting process of the cutting nozzle more stable.

[0016] Optionally, the supporting assembly further includes a handle, and the handle is connected to the stabilizing seat.

[0017] By adopting the above technical solution, a handle is provided on the stabilizing seat, so that the staff can adjust the position of the stabilizing seat conveniently.

[0018] Optionally, the handle includes a rotating part and an extending part, the rotating part is rotatably connected to the stabilizing seat, one end of the extending part is connected to the rotating part, and the other end extends to a side of the barrel away from the stabilizing seat, so that the extending part can rotate with the barrel during steel plate cutting.

[0019] By adopting the above technical solution, the extension part extends to the side of the gun barrel away from the stabilizing seat, and the staff can apply force to the stabilizing seat on the side of the gun barrel away from the stabilizing seat, thereby supporting the stabilizing seat and reducing the risk of flame injury. At the same time, the extension part is rotatably connected to the stabilizing seat through the rotating part to reduce the interference with the gun barrel during the steel plate cutting process.

[0020] Optionally, the handle further includes a gripping portion, which is a cylindrical structure, one end of which is fixedly connected to the extension portion.

[0021] By adopting the above technical solution, a cylindrical gripping portion is provided to facilitate the staff to apply force to the extension rod.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: limiting the moving path of the cutting nozzle by the positioning member so that the cutting nozzle can move along a circular path, thereby quickly completing the cutting of the circular steel plate and improving the cutting efficiency of the circular steel plate.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] Example 1

[0028] The cutting torch mainly comprises a handle, a barrel 2 and a cutting nozzle 1 vertically mounted at the end of the barrel 2. The handle is mounted at one end of the barrel 2 away from the cutting nozzle 1 to facilitate the worker to take and place for cutting.

[0029] The embodiment of the present application discloses a tool for rapid gas cutting of circular steel plates.

[0030] Reference Figure 1 A tool for quickly gas cutting a circular steel plate includes a positioning member 3, which is arranged on a gun barrel 2 in a direction parallel to the direction of a cutting torch nozzle 1 and is arranged parallel to the cutting nozzle 1 and spaced apart. The end of the positioning member 3 away from the gun barrel 2 extends to the side of the cutting nozzle 1 away from the gun barrel 2. During the steel plate cutting process, the end of the positioning member 3 away from the gun barrel 2 abuts against the steel plate, and the gun barrel 2 is made parallel to the steel plate. At this time, the gun barrel 2 is rotated with the positioning member 3 as a fulcrum to quickly complete the cutting of the circular steel plate.

[0031] Reference Figure 1 The positioning member 3 includes a sliding portion 31 and a supporting portion 32. The sliding portion 31 is a square block structure, and a sliding hole 33 is provided on the sliding portion 31. The sliding portion 31 is slidably sleeved on the gun barrel 2 along the length direction of the gun barrel 2. The supporting portion 32 is fixedly welded on the sliding portion 31. The sliding sliding portion 31 can change the distance between the positioning member 3 and the cutting nozzle 1, thereby changing the diameter of the circular steel plate being cut. It is convenient for the staff to cut circular steel plates of different sizes.

[0032] Reference Figure 1 The end of the positioning member 3 away from the barrel 2 is provided with a pointed cone 4, and the large end of the pointed cone 4 is welded to the end of the support portion 32 away from the barrel 2. During the process of cutting the steel plate, the tip of the pointed cone 4 abuts against the steel plate, which can facilitate the rotation of the cutting torch.

[0033] Reference Figure 1 The sliding part 31 is provided with a locking member 5, which is used to limit the sliding of the sliding part 31, thereby preventing the sliding part 31 from sliding relative to the barrel 2 during the cutting process. The stability during the cutting process is improved. The locking member 5 includes a threaded rod 51 and a knob 52. The sliding part 31 is provided with a threaded hole connected to the sliding hole 33. The threaded rod 51 is threadedly connected in the threaded hole, and the knob 52 is welded to one end of the threaded rod 51 away from the sliding part 31. Turning the knob 52 can drive the threaded rod 51 to rotate, so that it is convenient for the staff to turn the threaded rod 51 to lock the sliding part 31.

[0034] The implementation principle of the tool for fast gas cutting of circular steel plates in the embodiment of the present application is as follows: during the cutting process, the tip of the tip cone 4 abuts against the steel plate, and the barrel 2 rotates around the tip cone, so that the cutting nozzle 1 can move in a circular path to achieve cutting of the circular steel plate. Due to the limiting effect of the tip cone 4, it is convenient for the staff to control the moving path of the cutting nozzle 1, thereby improving the cutting efficiency of the steel plate.

[0035] Example 2

[0036] Reference Figure 2 The difference between this embodiment and the first embodiment is that in this embodiment, a supporting assembly 6 is provided on the supporting portion 32, and the supporting assembly 6 includes a stabilizing seat 61, which is in a truncated cone structure, and the small end of the stabilizing seat 61 faces the gun barrel 2. A through hole is provided on the stabilizing seat 61 at a position corresponding to the supporting portion 32, and the stabilizing seat 61 is slidably sleeved on the supporting portion 32 along the length direction of the supporting portion 32. The sliding stabilizing seat 61 can make the end face of the stabilizing seat 61 away from the gun barrel 2 flush with the top vertex of the pointed cone portion 4. Before cutting the steel plate, the tip of the pointed cone portion 4 is abutted at a specific position, and then the stabilizing seat 61 is slid so that the end face of the stabilizing seat 61 away from the gun barrel 2 is abutted against the steel plate, so that the supporting portion 32 can be limited, so that the supporting portion 32 is stably in a state perpendicular to the steel plate, and the stability during the steel plate cutting process is improved.

[0037] Reference Figure 2The supporting assembly 6 also includes a handle 62, which includes a rotating portion 621, an extension portion 622 and a gripping portion 623. The rotating portion 621 is a circular ring structure, and the rotating portion 621 is coaxially rotatably connected to the stabilizing seat 61. The extension portion 622 is a rectangular plate-like structure, one end of the extension portion 622 is welded to the rotating portion 621, and the other end extends along the length direction of the support portion 32 to the side of the gun barrel 2 away from the support portion 32. An avoidance hole is provided on the extension portion 622 corresponding to the gun barrel 2 to prevent the gun barrel 2 from interfering with the extension portion 622. The gripping portion 623 is a cylindrical structure, and the gripping portion 623 is fixedly connected to one end of the extension portion 622 away from the stabilizing seat 61 to facilitate the staff to apply force to the extension portion 622. A rubber sleeve (not shown in the figure) can be set on the gripping portion 623 to increase the friction coefficient of the surface of the gripping portion 623. Applying force on the side of the gun barrel 2 away from the stabilizing seat 61 can drive the stabilizing seat 61 to move and abut against the steel plate, making it convenient for the staff to support the stabilizing seat 61.

[0038] The implementation principle of a tool for fast gas cutting of circular steel plates in an embodiment of the present application is as follows: a stabilizing seat 61 is set so that the stabilizing seat 61 abuts against the steel plate. The stabilizing seat 61 can support the supporting part 32, thereby preventing the supporting part 32 from tilting, thereby facilitating the staff to control the distance between the cutting nozzle 1 and the steel plate and improving the cutting effect.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
