Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cutting equipment, in particular to a steel plate cutting mechanism for a forklift. Background Art

[0002] A large number of steel plates are required for welding and assembly during the production of forklifts. When cutting thick steel plates, the conventional method is to use a laser cutting machine to cut the steel plates. Announcement No. CN218983546U discloses a thick steel plate laser cutting device, including a support table, four support legs are symmetrically fixed to the bottom of the support table, a U-shaped plate is fixed to the top of the support table, a laser cutting head is arranged on one side of the U-shaped plate, a driving assembly for driving the laser cutting head to move horizontally is arranged on the U-shaped plate, a suction fan is fixed to the top of the U-shaped plate, a suction pipe is fixed to the suction end of the suction fan, a horizontal pipe is installed at one end of the suction pipe, and two vertical plates are symmetrically fixed to the top of the U-shaped plate. The utility model can absorb smoke generated during cutting into the dust collecting box by arranging a suction fan, a suction pipe, a horizontal pipe, a vertical plate, a connecting pipe, a dust hood, an air outlet pipe, a dust collecting box, an L-shaped plate and an activated carbon filter screen plate, and can retain metal particles in the smoke under the action of the activated carbon filter screen plate, so it is beneficial to the health of the workers.

[0003] However, the device has the following defects when in use: after the device places the steel plate on the support table, the dust hood will be above the steel plate, but when the laser cutting machine penetrates the steel plate, a large amount of dust will fall under the steel plate along the cutting seam, making it difficult for the device to collect the dust under the steel plate. To this end, we propose a steel plate cutting mechanism for a forklift. Utility Model Content

[0004] The purpose of the utility model is to provide a steel plate cutting mechanism for a forklift to solve the problems raised in the above background technology.

[0025] A slide groove is provided on the front side of the gantry 3, and a steel plate cutting structure is slidably connected to the inner wall of the slide groove. The steel plate cutting structure includes a guide block 7 slidably installed on the inner wall of the slide groove, and a cylinder 8 is fixedly installed on the upper surface of the guide block 7. The lower end of the cylinder 8 extends to the lower end of the guide block 7 and is fixedly installed with a laser cutting head 9. Driving the cylinder 8 to extend and retract can drive the laser cutting head 9 to approach the steel plate, so that the laser cutting head 9 can be used to cut the steel plate.

[0026] The inner wall of the gantry 3 is provided with a bottom dust suction structure, and the bottom dust suction structure includes a guide rod 4 fixedly installed on the inner wall of the gantry 3, and a slider 5 is slidably connected to the surface of the guide rod 4, and a bottom dust suction head 6 is fixedly installed on the front of the slider 5. The guide rod 4 can guide the moving trajectory of the bottom dust suction head 6, and a brush 17 is fixedly installed on the upper end of the bottom dust suction head 6, and the bottom dust suction head 6 is directly below the laser cutting head 9. The steel plate is placed on the upper surface of the steel plate placement rack 1. At this time, the bottom dust suction head 6 is below the steel plate, and the brush 17 will form a flexible contact with the steel plate to avoid damage caused by hard contact between the bottom dust suction head 6 and the steel plate.

[0027] The telescopic end sleeve of the cylinder 8 is provided with a top dust suction head 23, the laser cutting head 9 is located inside the top dust suction head 23, and the top dust suction head 23 and the bottom dust suction head 6 are both connected to the external dust suction system, and the telescopic end of the cylinder 8 is fixedly installed with a baffle 24, which is located between the top dust suction head 23 and the laser cutting head 9. The baffle 24 can limit the contact between the top dust suction head 23 and the laser cutting head 9. When the cylinder 8 drives the laser cutting head 9 to descend, the top dust suction head 23 will contact the upper surface of the steel plate, so that the dust generated by the cutting can be covered in the top dust suction head 23, thereby avoiding the large-scale diffusion of dust.

[0028] The inner wall of the gantry 3 is also provided with a linkage structure that can drive the bottom dust suction structure and the steel plate cutting structure to be linked. The linkage structure includes a first threaded column 10, a second threaded column 11 and a transmission shaft 12 which are respectively rotatably installed on the inner wall of the gantry 3. Both ends of the transmission shaft 12 are fixedly installed with a first bevel gear 13, and the first threaded column 10 and the second threaded column 11 are fixedly installed at one end close to the first bevel gear 13 with a second bevel gear 14 which meshes with the first bevel gear 13 for transmission. The left side of the gantry 3 is fixedly installed with a first motor 18 that can drive the first threaded column 10 to rotate.

[0030] The surfaces of the first threaded column 10 and the second threaded column 11 are respectively spirally driven with a first nut seat 15 and a second nut seat 16, and the front side of the first nut seat 15 is fixedly connected to the back side of the guide block 7, and the front side of the second nut seat 16 is fixedly connected to the back side of the slider 5. When the first threaded column 10 rotates, the spiral transmission between the first threaded column 10 and the first nut seat 15 can drive the laser cutting head 9 to slide left and right along the inner wall of the slide groove. At the same time, the driving structure can drive the gantry 3 to move forward and backward, so that the laser cutting head 9 can cut the steel plate horizontally and longitudinally, thereby increasing the cutting range.

[0031] When the first threaded column 10 rotates, the linkage structure will drive the second threaded column 11 to rotate synchronously. When the second threaded column 11 rotates synchronously, the second threaded column 11 and the second nut seat 16 are spirally driven to drive the bottom vacuum head 6 to move synchronously with the laser cutting head 9.

[0032] Compared with the prior art, when the first threaded column 10 rotates, the linkage structure will drive the bottom dust suction head 6 to move synchronously with the steel plate cutting structure. Since the bottom dust suction head 6 is always directly below the steel plate cutting structure and the top dust suction head 23 is provided on the surface of the cylinder 8, the dust generated by cutting above and below the steel plate can be efficiently collected.
