Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe cutting devices, and in particular to a laser cutting device for steel pipe production. Background Technology

[0002] Laser cutting technology uses a laser beam to irradiate steel and release energy to melt and evaporate the steel. Because the energy is very concentrated, it can rapidly heat the steel in a very small area to cut the steel to be processed.

[0003] When cutting steel pipes, the cutting is usually done along the circumference of the pipe to break it into several segments. Usually, the pipe needs to be rotated to ensure that the laser beam can accurately cut along the circumferential path, ensuring the roundness and precision of the cut. Therefore, a laser cutting device for steel pipe production is provided to achieve the rotation of the steel pipe and thus perform circumferential cutting. Utility Model Content

[0026] 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.

[0027] Example 1:

[0028] Reference Figure 1-6 A laser cutting device for steel pipe production includes a machine tool 1 with a laser cutting head mounted on it. It also includes: multiple mounting plates 2 fixedly connected to the machine tool 1 at equal intervals; a motor 201 fixedly connected to the machine tool 1; a rotating shaft 202 fixedly connected to the output end of the motor 201, used to rotate the steel pipe; a clamping assembly mounted on the mounting plates 2 for clamping the steel pipe; and a filtering assembly mounted on the machine tool 1 for absorbing the gas generated during cutting. The clamping assembly includes a telescopic cylinder 301 and a trapezoidal block 302. The rotating shaft 303 and two sets of telescopic cylinders 301 are fixedly connected to the machine tool 1. The trapezoidal block 302 is fixedly connected to the telescopic end of the telescopic cylinder 301. The rotating shaft 303 is rotatably connected to the trapezoidal block 302. The filter assembly includes an air pump 4 and a filter box 5. The air outlet of the air pump 4 is connected to the air inlet of the filter box 5. An activated carbon filter plate is installed inside the filter box 5. An opening 101 is provided on the machine tool 1. The telescopic cylinder 301 is fixedly connected inside the opening 101. Multiple sets of air intake ports 203 are evenly spaced on the mounting plate 2. The air intake ports 203 are connected to the air inlet of the air pump 4.

[0029] When using this device, the two ends of the steel pipe are hooked on the hooks of the gantry crane. The steel pipe to be cut is then placed on the mounting plate 1. The telescopic cylinder 301 is then activated, causing the rotating shafts 303 on the two sets of trapezoidal blocks 302 to contact the side wall steel pipe. At this point, the hooks on both ends of the steel pipe can be removed. The steel pipe can then be lifted by the two sets of rotating shafts 303 and the rotating shaft 202. The steel pipe can then be slowly rotated by the rotating shaft 202. Subsequently, the laser cutting head can be activated, the cutting position of the laser cutting head can be adjusted, and the steel pipe can then be cut. The rotation of the rotating shaft 202 achieves a circumferential cut, thus severing the steel pipe.

[0030] During cutting, the air pump 4 can be started to generate negative pressure at the air intake 203, thereby drawing in the gas from the mounting plate 2. If the cutting is in progress, the negative pressure will draw in the gas generated during cutting, preventing it from dissipating into the air and causing air pollution. The gas then enters the filter box 5 and is filtered by the activated carbon plate inside the filter box 5 to remove harmful substances.

[0031] Specifically, after a period of use, the activated carbon plate can be replaced to prevent the activated carbon from adsorbing too many impurities and affecting the gas filtration effect.

[0032] The laser cutting head in this device can be used in conjunction with a CNC cutting system, which enables precise positioning and cutting of steel pipes. The specific system can be the Siemens 840D system.

[0033] Example 2:

[0034] Reference Figure 1-6 A laser cutting device for steel pipe production is basically the same as that in Example 1, except that a baffle 6 is inserted into the air intake 203.

[0035] After the steel pipe is placed on the mounting plate 2 and clamped by the clamping assembly, the baffle 6 can be used to hold the two ends of the steel pipe in place, thereby achieving auxiliary fixation of the steel pipe and preventing accidental lateral movement of the steel pipe.

[0036] Specifically, the positioning of the steel pipe needs to be based on the position of the air intake 203. There may be situations where the baffle 6 cannot contact both ends of the steel pipe. In this case, it is necessary to add a pad to fill the gap and achieve stable fixation.

[0037] This invention, through the setting of the rotating shaft 202, can rotate the steel pipe during cutting. At the same time, the clamping component can clamp steel pipes of different sizes, so that they can be cut stably. Meanwhile, the filtering component can filter the gas generated during cutting, reducing the pollution of the surrounding environment by the gas generated during cutting.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
