Technical Field

[0001] The invention relates to the technical field of steel structure profile cutting, and in particular to an automatic laser cutting device for steel structure profiles. Background Art

[0002] Steel structural profiles refer to various metal profiles used to construct steel structure buildings. These profiles are usually made of steel through rolling, extrusion or other manufacturing processes. Common steel structural profiles include: I-beams, H-beams, angle steels, etc. Angle steel is a strip material with two sides perpendicular to each other, which can be used as a connector or reinforcement for a frame structure. The common processing method for angle steel is to use a laser cutting device to cut a certain length of angle steel profile into multiple lengths that meet the requirements.

[0003] In the current angle steel laser cutting process, angle steel profiles with a certain length are usually clamped by a clamp first to ensure stability during the cutting process and prevent displacement during the cutting process. However, the clamping position of a single clamp is limited, and the angle steel profiles are usually clamped and cut one by one, and the clamping and processing efficiency is not high; secondly, during the turning and feeding process during the cutting interval, bumps are prone to occur, resulting in damage to the surface of the finished steel product and reducing the quality of the finished product; thirdly, after the cutting process, the angle steel profiles are usually cut and stacked one by one by hand, which is inefficient and not conducive to cost saving, and there are certain safety hazards when manual labor is close to the cutting device.

The auxiliary part 93 is arranged between two adjacent alignment parts 94.

[0052] Reference Figures 10 to 12The interior of the auxiliary parts 93 is provided with an anti-collision component 95, which includes an air pump 951.

When the two inclined surfaces of the bottom wall of the auxiliary part 93 are close to the cut angle steel profile, the internal pressure of the vacuum pipe 952 is negative, and the longitudinal pipe section of the vacuum pipe 952 generates adsorption force on the cut angle steel profile at the suction port of the two inclined surfaces of the auxiliary part 93, preventing the cut angle steel profile section from being directly pushed down and falling, which would damage the surface of the finished steel product and affect the quality of the finished steel product.

[0054] The hydraulic rod 91 continues to push downward, driving the multiple cut angle steel profile segments and the angle steel profile segments to be cut to separate, until the hydraulic rod 91 drives the cut angle steel profile to move down to the top wall V-groove of the stacking seat 83. At this time, the alignment member 94 is engaged with the limit plate 82, and the top of the limit plate 82 pushes the pressure member 954 and the rubber plug 953 to move upward. The spring is compressed, and the rubber plug 953 moves up to release the obstruction to the end of the transverse pipe section of the exhaust pipe 952. Air enters from the end of the transverse pipe section of the exhaust pipe 952, and the negative pressure inside the exhaust pipe 952 disappears, releasing the cut angle steel profile segment, thereby unloading the cut angle steel profile segment.

[0055] The output end of the hydraulic rod 81 drives the stacking seat 83 to move downward from the initial height as the cut angle steel profile segments are stacked, ensuring that the cut angle steel profile segments are neatly stacked from bottom to top in the V-groove of the stacking seat 83, and the limit plate 82 prevents the cut angle steel profile segments from tipping left and right during stacking; when unloading, the pull-out long plate 86 is pulled to the right, driving the pull-out round rod 84 to slide in the stacking seat 83, and the pull-out round rod 84 pulls the unloading push plate 85 to slide in the stacking seat 83, and the unloading push plate 85 pushes the cut angle steel profile segments neatly stacked in the V-groove of the stacking seat 83 to move to the right, thereby realizing unified unloading of the stacked cut angle steel profile segments.

[0056] The specific operation steps of this steel structure profile automatic laser cutting device are as follows:

[0057] First, the left end of the angle steel profile to be cut is clamped and limited by adjusting the propulsion mechanism 3, the I-shaped piece 34 and the U-shaped frame 33 clamp and limit the left end of the angle steel profile to be cut, the middle part is supported by the supporting wheel 43, and the right end is limited by adjusting the clamping mechanism 1 5 and the clamping mechanism 2 6, and the clamping member 56 and the steering member 612 clamp and limit the right end of the angle steel profile to be cut; when cutting, the laser cutting arm group 7 is used to cut the angle steel profile to be cut below, and the motor 2 616 drives the steering member 612 and the corresponding The corresponding clamping members 56 drive multiple clamped angle steel profiles to be cut to rotate simultaneously, and the left end of the angle steel profile to be cut drives the rotating circular plate 32 to rotate on the side wall of the electric propulsion seat 31 to adapt to the turning direction of the angle steel profile to be cut; after a section of cutting is completed, during feeding, the output end of the motor 51 drives the screw rod 52 to rotate and drive the clamping seat 53 and the clamping member 56 to move forward and reset, and the electric propulsion seat 31 drives the angle steel profile to the right, the middle part of the angle steel profile slides on the top wall of the supporting wheel 43, and the right end of the angle steel profile slides on the top wall of the roller 622.

[0058] When the cut angle steel profile is fed to the right for unloading, the output end of the hydraulic rod 2 91 drives the support plate 92 and multiple auxiliary parts 93 to move down as a whole to approach the cut angle steel profile. When the two inclined surfaces of the bottom wall of the auxiliary part 93 are close to the cut angle steel profile, the internal negative pressure of the exhaust pipe 952 is generated, and the suction port of the longitudinal pipe section of the exhaust pipe 952 at the two inclined surfaces of the auxiliary part 93 generates an adsorption force on the cut angle steel profile, and continues to push downward. After the rubber plug 953 moves up, it releases the obstruction to the end of the transverse pipe section of the exhaust pipe 952, and air enters from the end of the transverse pipe section of the exhaust pipe 952. The negative pressure inside the exhaust pipe 952 disappears, and the cut angle steel profile segments are released for stacking. When unloading, the pulling and drawing elongated plate 86 is pulled to the right, and the unloading push plate 85 pushes the cut angle steel profile segments neatly stacked in the V-groove of the stacking seat 83 to move to the right, thereby achieving unified unloading.
