Description

Technical Field

[0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a reusable plasma cutting machine frame used for cutting steel plate parts. Background Art

[0002] The main features of the plasma cutting machine frames used in existing shipyards are as follows:

[0003] 1. The upper and lower frames of the plasma cutting machine use straight flat irons of equal specifications (8.0×100×5000mm) with a height of 100mm, and I-beams or angle steels are used as connecting supports in the middle.

[0004] 2. The distance between the straight flat irons is 150mm, and the cut small parts are easy to fall to the bottom of the tire frame.

[0005] 3. According to the properties of the plasma cutting machine, the width of the tire frame is consistent with the width of the cutting machine. The size of each set is 5000 (width) × 2160 (length) mm.

[0006] 4. As the plasma cutting machine cuts the material, the sediment generated in a certain period accumulates, causing serious damage to the surface of the tire frame, which directly affects the flatness of the tire frame and needs to be replaced.

[0007] There are several problems in the production and installation of existing tire frames:

[0008] 1. The spacing between the flat irons on the existing tire frame is 150mm. When cutting small parts, they easily fall onto the lower layer of the tire frame, where water accumulates, making it difficult to sort the parts. To address this issue, bridges are added between the parts during CNC nesting. After the cutting process, the bridges must be manually separated, and the connection points of the CNC parts must be manually polished and smoothed. This problem is particularly prominent when cutting large quantities of small parts.

[0009] 2. The tire frame is large in size. When the tire frame is severely damaged in the high-density area (where cutting equipment is frequently used), it will be damaged differently in the low-density area (where cutting equipment is less frequently used), where the wear is less severe. When the high-wear area reaches the replacement requirement, the entire tire frame needs to be replaced, shortening the service life of the low-density area.

[0010] 3. When the existing tire frame is used, cutting slag is easy to accumulate and difficult to clean. The large spacing also makes walking inconvenient and poses a safety hazard. To solve this problem, some slats are placed in the low-density area for people to walk when CNC cutting parts (cutting areas that are not frequently used).

[0011] 4. In the existing tire frame production, the gap between the upper and lower layers of flat iron parts is too large. When cutting small parts, a large number of them fall to the bottom of the tire frame, making it difficult for workers to pick them out. The cost of manual grinding of small parts connected by bridges increases, and the overall replacement cost of the tire frame increases (material waste in unused areas).

[0012] Based on the above technical problems, the present invention proposes a reusable plasma cutting machine frame for cutting steel plate parts, which can effectively control the installation accuracy, meet the horizontality requirements, and ensure the walking safety of personnel during construction, reduce the problem of falling cut parts, and reduce material production costs.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. That is, the embodiments described are only part of the embodiments of the present invention, rather than all embodiments.

[0036] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings:

[0037] A reusable tire frame for a plasma cutting machine is provided. The overall assembly and manufacturing method of the tire frame is completed by standardizing tire frame modules, designing dense module gaps, making the tire frame material lightweight, and adopting a sawtooth slot design for the tire frame intermediate support. The specific steps are as follows:

[0038] A plasma cutting machine frame consists of a water tank, a frame, and water. The frame's foundation is a steel water tank with dimensions of 5000mm wide, 43200mm long, and approximately 530mm high, and is constructed with steel plates around the edges.

[0039] The bottom of the water tank is divided into 20 separate water troughs using water tank steel plates 6. The size of each independent water trough is approximately 12.0×2180×5000mm and the height is approximately 350mm. The water tank wall 5 is reinforced with angle steel 2 with a specification of L150×90×10.0mm. It is about 280mm away from the upper end of the water tank and mainly serves to support the tire frame. Four groups of [20a channel steel supports are installed in the longitudinal direction of the water tank. The installation positions are respectively below the four groups of sawtooth slot parts in the middle. The sawtooth slot parts fall directly on the channel steel supports. The distance between the supports and the starting point on the left is 1200mm, 2400mm, 3600mm, and 3860mm. [10 channel steel supports are used in the horizontal direction along both sides of the module and are welded to the two-stage sawtooth slot parts to serve as horizontal supports.

[0040] Core part of the tire frame: tire frame module and middle serrated slot support design:

[0041] The tire frame modules come in two sizes: 3830×2160×270mm and 1130×2160×270mm, with 20 sets evenly arranged longitudinally. The tire frame modules are welded together with upper and lower high flat irons 3, lower flat irons 4, and a serrated slot 1.

[0042] The sawtooth slot parts are CNC-cut to dimensions of 15.0×170×2160mm. Flat irons are purchased as standard parts or CNC-cut. The high flat irons (3 sizes) are 8.0×100×3830mm and 8.0×100×1130mm, while the low flat irons (4 sizes) are 8.0×40×3830mm and 8.0×40×1130mm.

[0043] The high flat irons 8.0×100×3830mm and 8.0×100×1130mm are respectively inserted into the serrated slot 1 and fixed by welding. The low flat irons 8.0×40×3830mm and 8.0×40×1130mm are respectively installed on the platform of the serrated slot 1 and fixed by welding. The high and low flat irons are installed on both sides of the tire frame.

[0044] The tire frame module 3830×2160×270mm has a total of 4 serrated slot parts with a spacing of 1200mm. The tire frame module 1130×2160×270mm has a total of 2 serrated slot parts with a spacing of 885mm. There are 14 single-sided high flat irons 3 and 28 on the upper and lower sides. There are 13 single-sided low flat irons 4 and 26 on the upper and lower sides.

[0045] The tire frame modules are placed into the water tank from one side along the 5-meter width of the horizontal direction. The modules 3830×2160×270mm and 1130×2160×270mm are placed on the bottom longitudinal [20a channel steel support and the inner angle steel structure of the water tank wall. They are installed in sequence and placed into the water tank. Make sure that each module is tightly connected. After installation, fill the water tank with water to the same level as the top of the low flat iron. Finally, the 20 sets of tire frame modules form a whole and are tightly connected. The cutting steel plate 7 is hoisted onto the tire frame and supported by the main load-bearing point of the tire frame. The steel plate parts are then cut and used.

[0046] The content features of the present invention are:

[0047] The gap design of the flat irons in the tire frame module is encrypted, and the spacing between the flat irons is adjusted from the original 150mm to 80mm, which can avoid the problem of parts falling after the small parts bridge is eliminated; the use effect is good. Therefore, the bridge between the cutting parts can be eliminated, thereby reducing the workload of manual decomposition and subsequent parts processing, reducing construction costs, and improving work efficiency; when the equipment is running, it is more convenient and safe for workers to walk and check. According to the properties of the existing CNC cutting equipment and combined with actual production and use conditions, the tire frame module unit is designed to be divided into two parts in the width direction, which are 3830mm wide and 1130mm wide respectively. The 3830mm width part is a high-loss area and can be replaced according to the damage condition; the 1130mm width part is a low-loss area with a long service life and can be reused. According to the actual replacement frequency, the 3830mm width part is positioned as a standard module to reduce costs and improve use and replacement efficiency. See attached Figure 4

[0048] The present invention adopts a sawtooth slot design for the middle support of the tire frame, which is divided into upper and lower surfaces for installing high and low flat irons respectively. The main force point on the slot is slotted, and a flat iron with a height of 100mm (specifications are 8.0×100×3830mm and 8.0×100×1130mm) is inserted into the position. The support point of the slot is welded with a flat iron with a height of 40mm (specifications are 8.0×40×3830mm and 8.0×40×1130mm), and the height difference between the two is 25mm. The high flat iron at the main force point is mainly used to bear the weight of the cut steel plate, and the low flat iron at the support point is used to reduce the gap to prevent parts from falling, thereby reducing the use of materials and reducing the production cost. See attached. Figure 4

[0049] A water level mark is added inside the tire frame to reduce slag accumulation and increase service life by controlling the water level.

[0050] For further introduction of the attached drawings, Figure 1 The center tire frame module is divided into two sizes: the left module 3830×2160×270mm and the right module 1130×2160×270mm. The two modules are evenly arranged in 20 groups along the longitudinal direction.

[0051] Figure 2 To support the zigzag slot in the middle of the tire frame, high and low flat irons are welded to the slot structure in sequence, with a spacing of 80mm. Straight flat irons of different heights are welded to the middle slot support parts, with a height difference of 25mm. The high flat iron bears the weight of the cut steel plate, and the low flat iron is used to prevent small parts from falling to the bottom of the tire frame.

[0052] Figure 3 The high flat irons 8.0×100×3830mm and 8.0×100×1130mm are welded in the serrated slots and mainly bear the weight of the cut steel plates.

[0053] Figure 4 The platform of 8.0×40×3830mm and 8.0×40×1130mm medium and low flat irons is welded with serrated slots, which is mainly used to prevent the cut small parts from falling to the bottom of the frame and can more effectively reduce the accumulation of iron oxide after steel plate cutting.

[0054] A method for installing a reusable plasma cutting machine frame. Specific steps:

[0055] 1. Production of the tire frame module on the left side of the tire frame, 3830×2160×270mm: Take the 4 groups of slot parts in the middle as the reference (use tooling to fix the parts, and add inspection lines on the middle serrated slot parts for leveling and positioning installation). After positioning according to the position and size and passing the verification, install the high and low flat irons of the upper layer in sequence. The main stress points of the slots are slotted and inserted with a flat iron with a height of 100mm. The adjacent stress points are directly welded with a flat iron height of 40mm. The height difference of the flat irons installed between adjacent stress points is 60mm, the installation height difference is 25mm, and it is welded and fixed with a weld foot of 6mm. After welding is completed, the positioning and leveling are checked. When the accuracy is met, the tire frame is turned over, and the high and low flat irons on the other side are installed, welded and fixed, and the wires are pulled around for leveling to check the levelness of the tire frame to meet the accuracy and levelness requirements. 20 groups of each tire frame module need to be produced.

[0056] 2. Level measurement and tightness inspection inside the tire frame water tank: The inner angle steel structure of the surrounding wall and the longitudinal support at the bottom of the water tank must meet the accuracy requirements for level measurement. The bottom of the water tank also needs to be sealed. All must meet the requirements and be approved before the tire frame module is installed.

[0057] 3. Place the left module of the tire frame (3830×2160×270mm) into the water tank, and place it on the inner angle steel of the surrounding wall and the four sets of longitudinal supports in the middle. Place the right module (1130×2160×270mm) into the water tank, and place it on the middle set of longitudinal supports and the angle steel on the inner side of the surrounding wall. Adjacent sets must be tightly connected when installed.

[0058] 4. After the entire tire frame module is installed, the overall levelness of the tire frame needs to be measured and must meet the overall levelness requirements of the tire frame.

[0059] 5. Fill the water tank with water until the water level is flush with the top of the low flat iron, and pay attention to replenishing the water level in time.

[0060] 6. Place steel plates on the upper surface of the tire frame and move the tire frame up and down. The operation should be done slowly and it is forbidden to hit it too hard, which will affect the overall quality of the tire frame.

[0061] 7. The tire frame must be maintained daily when cutting steel plates. The iron oxide after cutting must be cleaned up in time, and cleaned every day to increase the service life of the tire frame.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
