Description

Technical Field

[0001] The utility model belongs to the technical field of loading racks, in particular to a loading rack for a laser cutting machine. Background Art

[0002] The laser cutting machine focuses 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, a slit is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] When cutting square steel pipes, the laser cutting machine needs to use a loading rack to transport the steel pipes to the laser cutting machine for cutting. The traditional loading rack cannot adjust the angle of the steel pipes when transporting square steel pipes, so that some steel pipes are in a standing state and some are in a lying state when transported to the laser cutting machine. During cutting, the position needs to be manually adjusted before cutting. This operation is time-consuming and laborious, affecting the cutting effect and efficiency. Utility Model Content

The second connecting block 221 is fixedly connected to the connecting plate 1, and the inclination of the V-shaped groove 224 is smaller than that of the feed trough 2; the small inclination of the V-shaped groove can slow down the impact of the steel pipe sliding down and further protect the steel pipe. The V-shaped groove 224 can ensure that the steel pipe has a uniform posture when falling, and all the steel pipes are at right angles on the side to fit the V-shaped groove 224.

[0028] The fixed reel 17 is located obliquely above the reel 16, and the track 18 is movably connected to the upper end of the fixed reel 17 and the two are in surface contact. After the track 18 is broken on the fixed reel 17, it moves downward to the top of the square frame 5 and is fixedly connected to the second connecting column 6; the track is in a relaxed state when storing steel pipes, and all the steel pipes are located below the feed trough 2. When the reel 16 reels the track 18, it will drive the steel pipes stored on the track to move upward, so that the steel pipes move to the entrance of the feed trough 2. Relaxing the track will cause the steel pipes to move to the bottom of the feed trough 2.

[0029] The gear at the upper end of the tooth chain 25 is fixedly connected to the first movable shaft 11, the gear at the lower end of the tooth chain 25 is fixedly connected to the drive motor 26, the support plate 31 is fixedly connected to the connecting plate 1, and the drive motor can rotate the first movable shaft 11 through the cooperation of the gear and the tooth chain 25, so that the fixed reel 17 rotates the interviewed crawler 18 to reel in or loosen; a sensor is provided above the material-blocking cylinder 24 of the present invention, and the sensor is prior art and will not be described in detail; the crawler, drive motor, tooth chain, gear, cylinder, movable shaft and connecting shaft of the present invention are all prior art and will not be described in detail.

[0030] Working principle: When the utility model is used, the square steel pipe to be cut is first placed on the crawler 18, and then the driving motor is started to make the reel 16 reel up the crawler 18 through the cooperation of the tooth chain 25, the gear and the first movable shaft 11, so that the steel pipe above the crawler 18 moves up to the entrance of the feed trough 2. At this time, the V-shaped groove 224 on the adjustment component rises to the upper end of the arc groove 3. When the steel pipe moves to the entrance of the feed trough 2, it passes through the sharp corner 33, so that the steel pipe slides into the feed trough in an inclined state. At the same time, the limit plate 29 will drop to the closing position. The appropriate position ensures that the steel pipe will only slide into the arc groove 3 through the feed trough alone, and the upper blocking cylinder will also move the rod upward, so that the steel pipe will stay on the upper blocking cylinder 34 when it slides into the feed trough 2. When the sensor senses that there is a steel pipe on the upper blocking cylinder 34, it will first relax the crawler 18 to remove the steel pipe that is not left at the entrance of the feed trough 2, and then start the third cylinder 212 on the pushing assembly to move the L-shaped plate forward, pushing the excess steel pipe out of the entrance of the feed trough 2 and dropping it onto the crawler 18, so that the upper blocking cylinder There are two steel pipes left. At the same time, the lower blocking cylinder 34 will raise the rod body, and the upper rod body will retract the rod body, so that the two steel pipes will fall onto the lower blocking cylinder 34. Then the pressing plate 30 will move to the top of the second steel pipe through the first cylinder 27 to clamp it. The support plate will support the steel pipe to prevent the pressing plate 30 from deforming when clamping the steel pipe. Then the lower blocking cylinder will retract the rod body, so that the first steel pipe will fall onto the V-groove 224. The V-groove 224 will make the right angles of the steel pipe fit each other, uniformly The falling steel pipe angle is adjusted, and the V-groove 224 is lowered by the fourth cylinder 222. At the same time, the lifting cylinder 19 drives the roller to rise to the lower end of the arc groove, so that the steel pipe slides to the upper surface of the roller inside the arc groove 3 through the set angle. In this way, the steel pipe can be in a flat state inside the arc groove 3, and then moved to the appropriate position for cutting by the roller 20. The position of each steel pipe when entering the arc groove 3 can be adjusted according to the above steps, so that a single steel pipe can slide to the inside of the arc groove 3 in a flat state each time to facilitate subsequent cutting.
