Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting machine processing, and in particular relates to an inclined supporting bed for a laser tube cutting machine. Background Art

[0002] Laser cutting is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] Laser tube cutting machine is a type of laser cutting, which is a device that cuts tubes by laser. At present, most laser tube cutting machines lift the tubes to be cut by variable diameter supports for cutting. When the tube cutting is completed, the remaining tube tails on the variable diameter supports need to be moved down, otherwise the long-term force on the variable diameter supports will cause the variable diameter supports to deform, thereby reducing the accuracy of the next cutting process. The traditional method of unloading is to hang the tube tails down by a crane, but it takes a lot of time to adjust the crane, which reduces work efficiency, and there is also a safety hazard of tube falling. Summary of the invention

[0004] The purpose of the present invention is to provide an inclined support bed for a laser pipe cutting machine in order to solve the problems that the traditional method of unloading pipe tails is to use a crane to lift them down, but this has low work efficiency and great safety hazards.

[0005] The present invention achieves the above-mentioned purpose through the following technical scheme: it includes a pipe cutting machine bed body, the pipe cutting machine bed body includes bases on both sides, a plurality of connecting frames are equidistantly arranged between the two bases, a plurality of variable diameter supports are arranged between the connecting frames, a slope fixing frame is arranged above each of the connecting frames, a slope plate is arranged between the slope fixing frames, the slope plate is provided with avoidance holes at positions corresponding to the variable diameter supports, a unloading device is arranged on one side of the pipe cutting machine bed body, the unloading device includes an L-shaped base, a plurality of L-shaped support plates are equidistantly arranged inside the L-shaped base, the L-shaped base is provided with mounting grooves at positions corresponding to the L-shaped support plates, the upper end of the L-shaped support plate is connected to the mounting groove via a rotating shaft, an electric telescopic rod is arranged between the lower end of the L-shaped support plate and the L-shaped base, an adjusting rod is arranged between the lower surfaces of the L-shaped support plates, and a limiting device is arranged on the lower surface of the L-shaped support plates.

[0006] Furthermore, two ends of the electric telescopic rod are respectively connected to the adjusting rod and the L-shaped base through a rotating shaft.

[0007] Furthermore, the L-shaped base is provided with a mounting groove at a position corresponding to the electric telescopic rod.

[0008] Furthermore, the limiting device includes a U-shaped top plate, the lower end of the U-shaped top plate is connected to the L-shaped support plate via a rotating shaft, limiting rods are symmetrically provided on both sides of the upper surface of the U-shaped top plate, the limiting rods penetrate the L-shaped support plate, and the L-shaped support plate is provided with adjustment grooves at positions corresponding to the limiting rods.

[0009] Furthermore, a limit block is provided at the upper end of the limit rod and above the L-shaped support plate.

[0010] Beneficial effects: The invention has reasonable design, simple and stable structure, strong practicability, and has the following beneficial effects:

[0011] 1. When it is necessary to remove the remaining pipes on the variable diameter support, lower the variable diameter support, and the variable diameter support will lower with the pipes. When the variable diameter support passes through the avoidance hole and is lower than the ramp plate, the pipes will fall on the ramp plate. At this time, the electric telescopic rod will lift the L-shaped support plate to make the L-shaped support plate and the ramp plate have the same angle, so that the pipes can roll smoothly onto the L-shaped support plate, avoiding the risk of the pipes falling directly.

[0012] 2. When the pipe rolls down into the L-shaped support plate, the electric telescopic rod retracts, driving the L-shaped support plate to rotate and descend. When it descends to almost horizontal, the U-shaped top plate receives the top force of the L-shaped bottom plate, and pushes the limit rod out from above the L-shaped support plate. This can limit the pipe and prevent it from rolling directly to the ground. This allows for quick and convenient unloading of pipe tails, improves safety, and avoids the risk of pipe falling.
