Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a laser cutting equipment for medium and thick plates of bridges. Background Art

[0002] In the process of bridge construction, a large number of medium and thick plates are needed, which are generally processed and formed by laser cutting equipment. Laser cutting equipment uses high-energy laser beams to instantly heat medium and thick plates to melt or vaporize them, thereby achieving the purpose of cutting. However, during cutting, the stripes at the bottom of the cutting surface are significantly coarse, and accompanied by serious slag sticking. The reason is that during the cutting process, the laser energy is difficult to penetrate into the bottom of the plate to be cut, and the bottom material is not fully melted. When the thick plate is cut, the bottom of the plate needs to be re-placed on the table for cutting without being cut off. In this way, the depth of the plate cutting surface will be affected, and different fractures will be caused around the side wall or bottom wall of the depth, reducing the cutting quality of the plate.

A second gas rod 48 is provided at the center of the top of the clamp block 47. A second gas cylinder 49 is provided on the upper part of the second gas rod 48 to match it. A second fixing plate 50 is provided at the bottom of the second cylinder 49. The top of the guide plate 45 is respectively fixed to the two sides of the bottom of the second fixing plate 50. The second gas rod 48 penetrates the second fixing plate 50. A shaft rod 1 is inserted in the middle of the lifting plate 46. The shaft rod 1 penetrates the clamp block 47. A pressure roller 29 is provided between the inner sides of the shaft rod 1. The pressure roller 29 is located above the thick plate, and shaft rods 2 are provided on both sides of the movable roller 39. The shaft rods 2 penetrate the column 40, and the end of the shaft rods 2 away from the movable roller 39 is provided with a driving arm 28, and the end of the driving arm 28 away from the shaft rod 2 is interspersed with shaft rods 3, and the inner ends of the shaft rods 3 are movably connected to the outer sides of the inner pillars 41, and the outer side of the shaft rods 3 on one side is connected to a driver 27, and the driver 27 is installed at the corresponding end on the inner side of the workbench 3.

[0034] A cavity is set in the area inside the workbench 3 at the opening 18, and the inner pillar 41 is located in the cavity. The moving roller 39 and the corner plate 44 pass through the opening 18 and abut the bottom of the support plate 17 above the pillar. When the thick plate on the support plate 17 is subjected to laser cutting, the moving roller 39 and the corner plate 44 below are against the bottom of the support plate 17, and cooperate with the auxiliary part 4 on one side to form a downward pressure on one side and an upward pressure on the other side. The cutting operation is achieved by using forces in different directions on both sides to avoid insufficient laser contact depth during cutting, inability to quickly cut off the thick plate, and difficulty in laser energy to penetrate under the plate during cutting.

[0035] Detailed usage and function of this embodiment:

[0036] Place the thick plate on the support pallet 17, adjust the appropriate position of the laser cutting head 2, and then drive the first cylinder 6 and the first gas rod 9 to produce telescopic movement, the first gas rod 9 drives the connecting end block 10 to move, and when the connecting end block 10 is pushed to one side, it will push the left side of the triangle plate 11 to rotate to the lower right, and the right end of the triangle plate 11 will rotate to the upper left. At this time, the right end of the triangle plate 11 will pull the lifting column 12 to slide upward on the guide rod 13, and the support pallet 17 will be pushed upward with the thick plate placed on the upper part. At this time, the laser cutting head 2 cuts the thick plate below. During the cutting process, when the laser energy cannot penetrate into the bottom of the plate, by driving the lifting column 12 to slide upward, the distance between the thick plate and the laser cutting head will gradually become smaller. When the limit column 15 pushes against one side of the thick plate, it provides a certain clamping effect for the cutting. Among them, the limiting column 15 extends with the cutting position, and generates a telescopic movement by driving the third cylinder 34 and the third gas rod 35, so that the third gas rod 35 drives the connecting plate 36 to push forward, and the connecting plate 36 drives the rightmost movable push plate 37 forward. The right movable push plate 37 will pull the adjacent movable push plates 37 forward in sequence through the connecting piece 38 connected at the bottom, and the rightmost movable push plate 37 pushes the connecting tube 51 forward, and the connecting tube 51 will push the limiting column 15 forward. The limiting column 15 stops after being pushed forward to the appropriate position. When the lifting column 12 slides upward, the limiting column 15 presses against the thick plate below, and the place where it presses against the column is just near the laser cutting head 2, so that when cutting, the limiting column 15 just presses against the thick plate near the column cutting, giving the thick plate a certain clamping property.

[0037] During the cutting process, the driver 27 is driven to operate at the same time, and the driver 27 drives the driving arm 28 to move. After the driving arm 28 rotates, it will pull the column 40 connected on one side to rotate to one side. After the column 40 rotates to the upper left, the movable roller 39 connected in between will pass through the opening 18 and press against the bottom of the upper support plate 17. At the same time, the movable roller 39 will also press the left corner support plate 44 to rotate to the left, and the right protruding block on the top of the corner support plate 44 will flip forward, causing the top surface to pass through the opening 18 and press against the bottom of the support plate 17. The bottom of this place is near the back of the laser cutting head 2, that is, the limit support column 15 is near the front, and the corner support plate 44 is near the back. At the same time, the second cylinder 49 and the second gas rod 48 are driven to produce telescopic movement, and the second gas rod 48 presses the clamping block 47 downward, and the clamping block 47 presses the lifting plate 46 to slide downward on the guide plates 45 on both sides, and the lifting plate 46 presses the thick plate below with the pressure roller 29 connected in the middle. At this time, a limiting area is formed around during cutting, and the groove formed by cutting the medium and thick plates, the lower part of the thick plate will be limited by the moving roller 39 and the corner plate 44 below, and its groove side will be limited. The side below the groove depth of the thick plate will be subject to an upward force, and the other side above the groove depth of the thick plate will generate a downward force, so that under the action of two opposite directions of force, the groove depth of the thick plate will facilitate the transmission of the laser, which is convenient for effective cutting of the bottom of the thick plate, and under the limitation of the forces in different directions near the groove depth, the depth position is maintained without being moved during the cutting action.

[0038] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
