Description

Technical Field

[0001] The invention relates to plate blanking, and in particular to a mobile cutting platform for a steel plate production line. Background Art

[0002] With the rapid development of industry, the demand for non-standard steel structural parts has increased, and as a result, the demand for plate (i.e. steel plate) cutting has also increased. Intelligent production lines such as plate loading, plate transportation, plate cutting, and automatic sorting will become the development direction of smart factories. The automatic loading and unloading, automatic cutting, automatic sorting, automatic stacking, and automatic transfer intelligent production lines in smart factories will greatly enhance manufacturing production capabilities.

[0003] Most of the existing steel plate cutting uses a fixed workbench, and the materials after cutting are transported by manually operated bridge cranes. This method has obvious limitations, especially in the context of the growing demand for automated production and green manufacturing, it exposes many problems, as follows: First, a large amount of slag and metal chips are usually generated during the cutting process. These slag and metal slag accumulate around the cutting machine, making it difficult to clean; the existing fixed workbench design is difficult to meet the needs of automated transportation and flexible processing. During the lifting and loading of steel plates, the cutting area of ​​the cutting machine needs to be emptied and wait for the steel plates; after cutting is completed, the cutting table needs to be occupied for sorting operations. The existing sorting usually uses cranes to transport until the cutting table is completely emptied before the next cutting work can be carried out. The cutting machine has a long waiting time and low production efficiency. Summary of the invention

[0004] In view of this, the present invention proposes a mobile cutting platform for a steel plate production line.

[0006] The beneficial effects are: the cutting platform of the present invention is movable as a whole, and can be used as a carrier and cutting tool for steel plates. After cutting, it is transported to the next process along the roller conveyor line for sorting. Each production line can be equipped with multiple mobile cutting platforms of the present invention to realize assembly line cutting and sorting of steel plates, shorten the waiting time of the cutting machine, and improve the cutting efficiency of steel plates; the cutting platforms have multiple smoke exhaust channels, and the exhaust fan can be used to achieve fixed-point smoke exhaust at the cutting site to reduce the impact of cutting smoke; the present invention uses a support grid connected by a supporting rack to support the steel plate. The slag and metal chips generated during the cutting process can fall into the smoke exhaust channel below, which can realize the centralized cleaning of the slag and metal chips and reduce the impact on the cutting station.

[0007] Preferably, the support frame includes a bottom frame, an upper frame arranged on the bottom frame through a plurality of first steel pipes, the bottom frame includes a lower long beam and a lower short beam fixed together, and also includes a connecting steel pipe and a bottom steel plate arranged between the lower long beam and the lower short beam, the bottom steel plate is provided with a fire-resistant layer; and a wear-resistant plate is provided at the bottom of the bottom frame.

[0009] More preferably, the refractory layer is paved with refractory bricks, and the thickness of the refractory layer is 20 mm to 25 mm. The beneficial effect is that due to the characteristics of the refractory bricks themselves, the slag is not easy to adhere to the refractory bricks after falling, which reduces the difficulty of slag cleaning and improves the cleaning efficiency. In addition, the refractory layer paved with refractory bricks can also isolate the thermal influence of high-temperature molten materials on the bottom steel plate, thereby extending the service life of the present invention.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-5 As shown, the mobile cutting platform for a steel plate production line of the present invention comprises a support frame 1 and a support platform arranged in the support frame 1, the support frame 1 and the support platform are detachably connected, the support platform is formed by a plurality of groups of support grids 2 arranged in the support frame 1 and connected in sequence, each group of support grids 2 comprises a pair of end plates 2.1 and a plurality of support racks 2.2 fixedly connected between the two end plates 2.1 at intervals, the plurality of support racks 2.2 are arranged along the width direction of the support frame 1, the two end plates 2.1 are respectively fixed on the two long sides of the top of the support frame 1, and the end plates 2.1 and the support frame 1 are connected by bolts; The present invention designs the support platform into multiple groups of support grids 2, which are independently installed and easy to disassemble and assemble, thereby realizing partial replacement of the support platform and reducing maintenance costs. In addition, the present invention uses the support grids 2 connected by the support racks 2.2 to support the steel plate, and the slag and metal chips generated during the cutting process enter the support frame 1 through the gaps between the support racks 2.2, thereby solving the problem of slag accumulation. A plurality of partitions 1.13 arranged along the width direction are arranged in intervals in the support frame 1. The support frame 1, the plurality of partitions 1.13 and the plurality of support grilles 2 enclose a plurality of exhaust passages F arranged along the width direction. A fan 4.1 and an exhaust hood 4.2 are installed on the walking truss 4.4 of the cutting machine. The fan 4.1 and the exhaust hood 4.2 are located on both sides of the exhaust passage F. The exhaust hood 4.2 is connected to the bellows 4.3 on the ground. During actual cutting, since the walking truss 4.4 of the cutting machine can move along the rails, the fan 4.1 and the exhaust hood 4.2 can be moved so that they are always located on both sides of the exhaust passage F at the cutting operation location, and smoke and particles generated during the cutting process are quickly sucked away, effectively reducing cutting smoke and optimizing the working environment.

[0022] The mobile cutting platform of the present invention can be used as a carrier and cutting tool for steel plates. After cutting, they are transported to the next process along the roller conveyor line for sorting. Each production line can be equipped with multiple mobile cutting platforms of the present invention to realize assembly line cutting and sorting of steel plates, shorten the waiting time of the cutting machine, and improve cutting efficiency.

[0023] Combination Figure 1It can be seen that the support frame 1 of the present invention adopts a rectangular steel pipe as the main frame, which includes a bottom frame, an upper frame arranged on the bottom frame through a plurality of first steel pipes 1.1, the bottom frame includes a lower long beam 1.3 and a lower short beam 1.4 fixedly connected together, and also includes a connecting steel pipe 1.12 arranged between the lower long beam 1.3 and the lower short beam 1.4 to ensure the structural strength of the bottom frame, the bottom frame also includes a bottom steel plate 1.5, and a fire-resistant layer 1.9 is arranged on the bottom steel plate 1.5; wherein, the upper frame is formed by the upper long beam 1.2 and the upper short beam 1.6 fixedly connected end to end in sequence, and the upper long beam 1.2, the upper short beam 1.6, the lower long beam 1.3 and the lower short beam 1.4 all adopt rectangular steel pipes to ensure the supporting performance of the support frame 1.

[0024] Combination Figure 2 It can be seen that the partition corresponding to the connecting steel pipe 1.12 is a fixed partition, and the other partitions are detachable partitions. Multiple pairs of mounting plates can be installed between the upper long beam and the lower long beam, and the two ends of the detachable partitions are fixed to the mounting plates by bolts for easy replacement; the upper long beam 1.2 and the lower long beam 1.3, and the upper short beam 1.6 and the lower short beam 1.4 are fixed together by multiple first steel pipes 1.1; a plurality of pairs of reinforcing angle steels 1.8 are also fixedly connected between the two lower long beams 1.3, and the bottom steel plate 1.5 is fixedly connected to the corresponding reinforcing angle steel 1.8. The reinforcing angle steel 1.8 can prevent the bottom steel plate 1.5 from settling during use.

[0025] Combination Figure 1-2 and Figure 4 It can be seen that a positioning structure is also provided on the upper part of the support frame 1, and the positioning structure includes a fixed plate 1.14 (parallel to the upper short beam) arranged between adjacent support grids 2 and a plurality of groups of positioning plates 1.16 (parallel to the upper long beam) corresponding one to one with the support grids 2, and the two ends of each pair of positioning plates 1.16 are correspondingly fixed on the two upper long beams 1.2 of the support frame 1, and each group of positioning plates 1.16 is fixedly connected to the fixed plate 1.14, and each positioning plate 1.16 has a plurality of positioning slots corresponding one to one with the support racks 2.2 of the support grids 2.

[0026] During installation, the support grid 2 can be placed in the support frame 1, and its support rack 2.2 can be clamped on the positioning plate 1.16, and then the end plates 2.1 of the support grid 2 are respectively fixedly connected to the upper long beam 1.2. Multiple groups of support grids 2 are fixedly connected to the support frame 1 in sequence to realize the installation of the support platform on the support frame 1, which can be used to support steel plates. During cutting, since the support grid 2 has a gap, the slag and debris generated by cutting fall onto the refractory layer 1.9 below, avoiding falling onto the cutting station, thereby reducing the cleaning difficulty of the cutting station. The refractory layer 1.9 has the characteristic of not adhering to slag, which can realize the rapid cleaning of slag and reduce the cleaning difficulty; during the cutting process, since the cutting machine is movable, it can drive the fan 4.1 and the exhaust hood 4.2 to move synchronously, so that the fan 4.1 and the exhaust hood 4.2 are located on both sides of the exhaust channel F corresponding to the cutting position, and the smoke and particles generated during the cutting process are quickly sucked away, effectively reducing the cutting smoke and optimizing the working environment.

[0027] During actual installation, the refractory layer 1.9 is preferably constructed of refractory bricks and refractory mud. The thickness of the refractory layer 1.9 is 15 mm to 40 mm, which can not only reduce the difficulty of cleaning the slag, but also isolate the thermal impact of the high-temperature molten material on the bottom steel plate 1.5, thereby extending the service life of the support frame 1 of the present invention. Since the edge of the bottom frame has a lower long beam 1.3 and a lower short beam 1.4 and has a certain height, the refractory layer 1.9 is located inside the bottom frame, which can effectively prevent the slag from falling during transportation. In addition, the support rack 2.2 is preferably made of high-strength and high-temperature resistant materials, such as alloy materials, to reduce the impact of high temperature on the support rack 2.2 and ensure the support performance of the support rack 2.2.

[0028] Combination Figure 1-2 It can be seen that a horizontal wear-resistant plate 1.7 is fixedly connected to the bottom of the bottom frame; each side plate 1.10 in the width direction of the support frame is provided with an upwardly protruding guide head 1.11, so that the support frame is similar to a sled structure, which is convenient for entering and exiting the roller conveyor line, thereby realizing the free flow of the present invention on the production line.
