Description

Technical Field

[0001] The present application relates to the technical field of laser cutting, and in particular to a cutting device based on chuck follower bevel cutting. Background Art

[0002] The laser cutting machine focuses the laser 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. The chuck is a part of the laser cutting machine, mainly used to clamp and fix the pipe.

[0003] Laser bevel cutting requires that in a complete workpiece cutting, the cutting height, knife gap compensation, knife edge offset compensation, feed speed, and corner transition must be adjusted synchronously and in real time with the change of the bevel angle to achieve the correct cutting size, bevel angle, and satisfactory surface quality.

[0004] The existing laser cutting machine includes a machine tool, a first chuck slidably connected to the machine tool and used to fix the pipe, a second chuck fixed to the machine tool and used to drive the pipe to rotate, and a swing head installed on the machine tool near the second chuck, where the swing head is the laser cutting head.

[0005] With respect to the above-mentioned related technologies, when laser cutting is performed on a pipe, when the swing head needs to swing and cut along the length direction of the pipe, the first chuck needs to drive the pipe to move first, and then start cutting. On the one hand, this wastes time, and on the other hand, the pipe will shake during the movement, affecting the cutting effect. Summary of the invention

[0006] In order to improve the efficiency and effect of pipe cutting, the present application provides a cutting device based on chuck follower bevel cutting.

[0007] The present application provides a cutting device based on chuck follow-up bevel cutting, which adopts the following technical solution:

[0008] A cutting device based on chuck follower bevel cutting includes a machine tool, a first chuck for clamping and fixing a pipe is slidably connected to the machine tool, a second chuck for clamping the pipe is slidably connected to the machine tool, the sliding directions of the first chuck and the second chuck are consistent with the length direction of the pipe, a swing head for laser cutting the pipe is provided on the machine tool, the swing head is installed on the second chuck, and moves along the length direction of the pipe with the second chuck, and a driving member is provided on the machine tool for driving the second chuck to move.

[0009] By adopting the above technical solution, the first chuck and the second chuck clamp and fix the pipe, and the swing head performs laser cutting on the end of the pipe. When the swing head needs to cut along the length direction of the pipe, the driving member drives the second chuck to move in a specified direction, and the swing head follows the second chuck to move to a specified position to continue cutting. The first chuck does not need to move, and the swing head can cut while following the movement of the second chuck, which saves time and does not require the pipe to move, thereby improving the cutting efficiency and cutting effect of the pipe.

[0010] Optionally, a collecting trough is provided on the upper surface of the machine tool at a position directly below the moving path of the swing head, an inclined intercepting net is fixed near the top of the collecting trough, and a collecting hole is provided on the inner wall of the collecting trough at the bottom end of the intercepting net; a mesh conveyor belt is provided in the collecting trough below the intercepting net, and a recovery hole is provided in the collecting trough at one end of the mesh conveyor belt; the outer ends of the collecting hole and the recovery hole are both located on the same side of the machine tool, and a closing plate for closing the outer ends of the collecting hole and the recovery hole is provided on the machine tool; an exhaust hole is provided at the bottom of the inner wall of the collecting trough, an exhaust fan is installed in the exhaust hole, a filter box connected to the exhaust hole is provided on one side of the machine tool, and a filter component for filtering debris and dust is provided in the filter box.

[0011] By adopting the above technical scheme, the exhaust fan is started for exhaust, the cut pipes fall directly into the collection trough, and are intercepted by the interception net and rolled into the collection hole. The cut waste passes through the interception net and falls onto the mesh conveyor belt, and is transported to the recovery hole by the mesh conveyor belt. The pipes and waste can be taken out by opening the closing plate; the debris and dust pass through the mesh holes on the mesh conveyor belt and enter the exhaust hole, and then enter the filter box to be filtered by the filter assembly. During exhaust, the closing plate always closes the collection hole and the recovery hole to ensure that the wind speed at the opening on the collection trough is the maximum, so that the debris and dust are collected and processed with the maximum efficiency, thereby realizing the integrated effect of automatic material collection, waste collection, and automatic collection and processing of debris and dust.

[0012] Optionally, the mesh conveyor belt includes two drive rollers rotatably connected to the collecting tank, a conveyor mesh belt sleeved on the two drive rollers, and a motor fixed on the outside of the machine tool, and the motor is coaxially fixed to one of the drive rollers.

A rotating shaft is rotatably connected in the collecting trough and is located below the top plate and parallel to the transmission roller. The rotating shaft is connected to one of the transmission rollers through a sprocket and a chain, and a cam for pushing the top plate is fixedly sleeved on the rotating shaft.

[0015] By adopting the above technical solution, when the mesh conveyor belt is working, the transmission roller drives the rotating shaft to rotate through the sprocket and the chain, and the cam pushes the top plate at intervals to make the top plate move up and down, which can lift up the debris and dust deposited on the upper surface of the top plate and disrupt the airflow above the top plate, so that the exhaust fan can more thoroughly draw the debris and dust out of the collection tank for processing.

[0016] Optionally, the filter assembly includes a mesh and a mesh cloth installed in a filter box, an air outlet is provided on a side of the filter box away from the air exhaust hole, and the mesh is located on a side of the mesh cloth away from the air outlet.

[0017] By adopting the above technical solution, the debris and dust entering the filter box are filtered and intercepted by the mesh and the mesh cloth in turn, and the filtered gas is discharged from the air outlet, thereby improving the filtering effect of the debris and dust.

[0018] Optionally, a reinforced fan is installed at the air outlet.

[0019] By adopting the above technical solution, strengthening the setting of the fan can improve the efficiency of drawing debris and dust into the filter box, and further improve the collection and treatment effect of debris and dust.

When the closing plate closes the outer ends of the collecting hole and the recovery hole, its lower end surface fits with the upper surface of the upper cover plate. The upper cover plate is provided with a fixing component for fixing the closing plate.

[0023] By adopting the above technical solution, after the upper cover plate closes the top of the filter box, the closing plate rotates downward and closes the outer ends of the collection hole and the recovery hole. At this time, the upper cover plate is restricted by the closing plate and cannot be opened. The closing plate is then fixed by the fixing assembly on the upper cover plate, so that the closing plate and the upper cover plate are both fixed, thereby improving the convenience of operation.

[0024] Optionally, the fixing assembly includes a fixing plate, a spring and a top block, wherein the fixing plate is fixed to the upper surface of the upper cover plate, the spring is fixed to the side wall of the fixing plate facing the closing plate, and the top block is fixed to the end of the spring and is used to tighten the closing plate.

[0025] By adopting the above technical solution, the closing plate can be rotated downward to close the collecting hole and the recovery hole by pulling the top block, and then the top block is released, and the spring presses the top block against the closing plate, and the closing plate is pressed against the side wall of the machine tool, thereby improving the fixing efficiency of the closing plate and the upper cover plate.

[0026] Optionally, the driving member is a pneumatic cylinder or a hydraulic cylinder.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1.

The first chuck does not need to move, and the swing head can cut while following the movement of the second chuck, which saves time and does not require the pipe to move, thereby improving the cutting efficiency and cutting effect of the pipe;

[0029] 2. The cut pipes fall into the collection tank and are intercepted by the interception net and then roll into the collection hole. The cut waste passes through the interception net and falls onto the mesh conveyor belt and is transported to the recovery hole by the mesh conveyor belt. The debris and dust pass through the mesh holes on the mesh conveyor belt and enter the exhaust hole, and then enter the filter box to be filtered by the filter assembly, thus realizing the integrated effect of automatic material collection, waste collection, and automatic collection and treatment of debris and dust.

[0030] 3. After the upper cover plate closes the top of the filter box, the closing plate rotates downward and closes the outer ends of the collection hole and the recovery hole. At this time, the upper cover plate is restricted by the closing plate and cannot be opened. The closing plate is then fixed by the fixing assembly on the upper cover plate, so that the closing plate and the upper cover plate are both fixed, thereby improving the convenience of operation.
