Description

Technical Field

[0001] The utility model belongs to the technical field of laser tube cutting machines, and particularly relates to a slag removal device for tube cutting machines. Background Art

[0002] A laser tube cutting machine is a machine that can cut tubes using a high-power density laser beam. Its working principle is to use a focused high-power density laser beam to irradiate the material, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time use a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the material.

[0003] Therefore, when using a laser tube cutting machine to cut tubes, a certain amount of waste gas and waste slag will be generated. In addition, the waste slag generated during laser cutting can easily spray and adhere to the inner wall of the tube, leaving traces of welding slag on the tube wall that are difficult to remove, affecting the appearance and use. In order to address the impact of welding slag on the tube wall during cutting and the need for manual secondary cleaning, some existing tube cutting machines have begun to be equipped with dust and slag removal devices to absorb the waste slag generated during the cutting process. In this way, when the laser tube cutting machine heats and cuts the tube, the droplets, gas, and solid particles generated can be discharged from the tube through the slag receiving head under the suction effect of negative pressure, reducing the adhesion of hot-melt metal slag on the inner surface of the tube. Moreover, even if these droplets and solid particles cannot be directly sucked out, they can fall into the slag receiving port. As the slag receiving head withdraws and detaches from the tube after the cutting is completed, the inner surface of the tube to be cut is kept clean.

[0004] However, the existing dust and slag removal devices still have certain limitations in actual application: the structure of the existing dust and slag removal devices is relatively fixed. When they are installed on the laser tube cutting machine, they cannot adjust their own state to achieve the switching of the slag cleaning function between the online state and the offline state. It can only be achieved by disassembling and assembling the entire device on the laser tube cutting machine. Therefore, there is a problem of inflexibility when using it. Utility Model Content

[0005] The purpose of the utility model is to propose and design a slag removal device for a pipe cutting machine to address the problem that the existing dust and slag removal device cannot realize the free switching of the slag cleaning function between the online state and the offline state by adjusting its own state, so as to overcome the above problem and improve the flexibility of the entire device and the laser pipe cutting machine.

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is as follows: a slag removal device for a pipe cutting machine, comprising a slag removal base and a slag removal rod, wherein the upper end of the slag removal base is slidably mounted with two frames via slag removal guide rails, and each of the two frames is rotatably mounted with a support swing arm, wherein one support swing arm is provided with a support assembly, and the other support swing arm is provided with a clamping assembly; one end of the slag removal rod is fixed to the clamping assembly, and the other end is placed on the support assembly. In this way, in addition to realizing the follow-up slag removal function through the movement of the two frames, the position of the support assembly and the clamping assembly can be flexibly adjusted by rotating the two support swing arms. That is, when the laser pipe cutting machine does not need to use the slag removal device for the pipe cutting machine, there is no need to dismantle the entire device as a whole. The two support swing arms only need to be rotated to lift the support assembly and the clamping assembly to convert the slag removal device for the pipe cutting machine from an online state to an offline state; conversely, the two support swing arms only need to be rotated in the opposite direction to convert the slag removal device for the pipe cutting machine from an offline state to an online state, thereby improving the flexibility of the entire device and the laser pipe cutting machine.

[0007] Furthermore, one end of the frame is provided with two rotating support plates, the lower part of the rotating support plate is provided with a bushing, the upper part of the rotating support plate is provided with an arc-shaped groove, and the center of the arc-shaped groove is the same as the center of the bushing; one end of the support swing arm is located between the corresponding two rotating support plates, and both sides of the support swing arm are provided with an optical axis and a connecting hole in sequence from bottom to top, the optical axis is rotatably installed in the corresponding bushing, one end of the connecting piece abuts against the outer side of the arc-shaped groove, and the other end of the connecting piece passes through the corresponding arc-shaped groove and the connecting hole in sequence and is threadedly connected to a locking piece, or the other end of the connecting piece passes through the corresponding arc-shaped groove and is threadedly connected to the corresponding connecting hole. In this way, when it is necessary to rotate the support swing arm, the connecting piece can be first manipulated to loosen the connection between the support swing arm and the rotating support plate, and then the support swing arm can be rotated in the corresponding direction. After it is rotated to the appropriate angle, the connecting piece can be manipulated to tighten the support swing arm and the rotating support plate.

[0008] Furthermore, a knob handle is provided at one end of the connecting piece, and the knob handle can be used to facilitate operation by staff.

[0011] Furthermore, sensing part 1 and sensing part 2 are respectively installed at both ends of the slag cleaning base, and a sensing limiter 1 is provided on the frame close to the sensing part 1, and the sensing limiter 1 can trigger the sensing part 1; a sensing limiter 2 is provided on the frame close to the sensing part 2, and the sensing limiter 2 can trigger the sensing part 2, and the positioning of the frame close to the sensing part 1 is achieved through the cooperation between the sensing part 1 and the sensing limiter 1, and the positioning of the frame close to the sensing part 2 is achieved through the cooperation between the sensing part 1 and the sensing limiter 1, and the positioning of the frame close to the sensing part 2 is achieved through the cooperation between the sensing part 2 and the sensing limiter 2.

[0012] Furthermore, the clamping assembly includes at least one clamping bracket installed on the corresponding support swing arm, and a clamp is detachably installed on one side of the clamping bracket. A clamping hole is provided between the clamp and the clamp, and the slag cleaning rod can be clamped and fixed through the clamping hole.

[0013] Furthermore, the support assembly includes a support seat, a slide, and a stopper. The support seat is mounted on the corresponding support swing arm at one end close to the clamping assembly, and a support groove is provided on the upper end of the support seat.

[0014] Furthermore, a drag chain slot and a drag chain are provided on one side of the slag cleaning base, and the lines connected to the motor reducers on the two racks are protected by the drag chain slot and the drag chain.

It is only necessary to rotate the support swing arm 1 and the support swing arm 2 to lift the support assembly and the clamping assembly to convert the tube cutting machine slag removal device from an online state to an offline state; conversely, it is only necessary to rotate the support swing arm 1 and the support swing arm 2 in the opposite direction to convert the tube cutting machine slag removal device from an offline state to an online state, thereby improving the flexibility of the entire device and the laser tube cutting machine. Moreover, when using the present invention, it is also possible to select bases with different heights according to the model of the laser tube cutting machine, or to install support legs under the base to adapt to different models; and according to the model of the processed pipe, replace the slag heads with different diameters to meet the slag removal needs of different models of square or round tubes.
