Description

Technical Field

[0001] This utility model relates to the field of forklift processing and cutting equipment, and more specifically, to a forklift front fork cutting and processing device. Background Technology

[0002] In the forklift manufacturing industry, the cutting and machining of the forklift front tip is one of the key processes. In the traditional forklift front fork cutting process, the forklift front fork is usually placed directly on a flat surface for cutting, or the forklift front tip is suspended in the air.

[0003] Due to the lack of proper support and fixing structures, forklift forks are prone to stress concentration during flame cutting, leading to significant free deformation at the cutting point and severely affecting the dimensional accuracy and structural strength of the fork. Furthermore, the lack of an effective height guide device during flame cutting makes it difficult to maintain a stable cutting height, resulting in inconsistent cutting depths and failing to meet production accuracy requirements. This not only increases the scrap rate but also reduces production efficiency and raises production costs. Utility Model Content

[0006] Furthermore, the above solution includes four support legs, each of which is equipped with a telescopic cylinder. The tops of the four telescopic cylinders are connected to a grid, and the grid is provided with several toothed plates at intervals, with hollow areas formed between the toothed plates.

[0007] Furthermore, the above solution includes a waste bin for collecting waste materials located below the hollowed-out area.

[0008] Furthermore, the above solution includes a support plate that is mounted on the grille, with the top surface of the plate flush with the top surface of the hollow area, and the size of the plate being smaller than the tip of the forklift front fork.

[0009] Furthermore, the above solution includes a heating plate, which is disposed on the grille and a heating seat is mounted on the heating plate. The top surface of the heating seat is flush with the top surface of the hollow area, and the size of the heating seat is smaller than the tip of the forklift front fork. A temperature sensor is mounted on the heating seat.

[0010] Furthermore, the temperature sensor works in conjunction with the heating plate to uniformly preheat the tip of the forklift front fork to 50-80°C before cutting.

[0011] Furthermore, the above solution includes a mounting bracket, which is disposed on the grid. An adjusting screw is vertically threaded onto the mounting bracket, a crank is connected to the top of the adjusting screw, and a pressure seat is rotatably connected to the bottom of the adjusting screw.

[0012] Furthermore, the above solution includes a rubber pad on the bottom surface of the pressure seat.

[0013] Furthermore, the above solution includes a mounting base, on which a flame cutting gun is mounted.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides local support for the bottom surface of the fork front tip by setting a support part smaller than the front tip of the fork, which effectively disperses the stress generated during flame cutting, greatly reduces stress concentration, and reduces the risk of deformation of the fork front fork during cutting from the source. In addition, the clamping of the forklift front fork by the fixing part further restricts the degree of freedom of the forklift front fork during the cutting process. The support part and the fixing part cooperate with each other to form a stable fixing system, which effectively controls the free deformation of the forklift front fork during cutting and ensures the dimensional accuracy and structural stability of the front fork after cutting. In addition, the guide added to the flame cutting gun ensures that the flame cutting gun moves at a fixed height on the forklift fork, keeping the cutting height stable at all times, thereby ensuring consistent cutting depth, significantly improving the precision of cutting and meeting the needs of high-quality production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: A forklift front fork cutting and processing device, as shown in the attached document. Figure 1 As shown, the device includes a placement part 1 for horizontally placing a forklift fork and a flame cutting gun 2 for cutting the tip of the forklift fork. The placement part 1 has a planar support part 3 for supporting the bottom surface of the tip of the forklift fork and is smaller than the tip of the forklift fork. It also has a fixing part 4 for fixing the forklift fork to reduce free deformation during cutting. In addition, the flame cutting gun 2 is equipped with a guide part 5, which can move at a fixed height on the forklift fork to keep the cutting height of the flame cutting gun 2 stable.

[0019] In the implementation of this utility model, after the forklift fork is placed on the placement part 1, the support part 3 on the placement part 1 provides local support with a planar structure smaller than the tip of the forklift fork, which reduces the stress concentration at the tip of the forklift fork during the cutting process by the flame cutting gun 2. Subsequently, the forklift fork is restricted by mechanical clamping by the fixing part 4. The two work together to reduce free deformation during cutting. In addition, by adding the guide part 5, the flame cutting gun 2 can move at a fixed height on the forklift fork under the action of the guide part 5, ensuring the stability of the cutting height of the flame cutting gun 2, thereby ensuring consistent cutting depth and meeting the accuracy standard, and realizing precise and stable cutting processing of the tip of the forklift fork. In practical use, place the forklift fork horizontally on the support part 3 of the placement part 1, and use the fixing part 4 to firmly fix the forklift fork to ensure that it will not shift or shake during processing. Then, according to the cutting requirements of the front tip of the forklift fork, adjust the position of the guide part 5 on the flame cutting gun 2, set and fix the height between the flame cutting gun 2 and the fork to ensure stable cutting height. Finally, start the flame cutting gun 2, so that it moves along the forklift fork according to the preset marked path under the drive of the guide part 5, and use the high temperature of the flame to cut the front tip of the fork.

[0020] For the above scheme, please refer to the appendix. Figure 1 As shown, the placement unit 1 includes four support legs 11, each of which is equipped with a telescopic cylinder 12. The tops of the four telescopic cylinders 12 are connected to a grid 13 that facilitates material leakage during the cutting process. By controlling the stroke of the telescopic cylinders 12, the height of the grid 13 can be adjusted to adapt to the processing requirements of different working environments. Several toothed plates 14 for placing the forklift forks are arranged at intervals on the grid 13, and a hollow area is formed between each toothed plate 14 to facilitate the falling of cutting waste. In addition, a waste bin 15 for collecting waste is provided below the hollow area.

[0021] In one embodiment of the above solution, the support 3 is a flat plate seat in the prior art. The flat plate seat is set on the grille 13, and the top surface of the flat plate seat is flush with the top surface of the hollow area, so that the flat plate seat can stably support the tip of the forklift front fork, forming a flat support surface and ensuring that the forklift front fork is placed stably. In addition, since the size of the flat plate seat is smaller than the tip of the forklift front fork, it only contacts the bottom surface of the tip, which will not affect the cutting and avoids excessive local stress concentration caused by the shape error of the forklift front fork itself and uneven surface when there is a large area of ​​contact, thus ensuring the cutting accuracy and quality.

[0022] In another embodiment, refer to the appendix Figure 1As shown, the support part 3 includes a heating plate 31, which is disposed on the grille 13. A heating seat 32 for contacting the bottom surface of the fork front tip is installed on the heating plate 31. The top surface of the heating seat 32 is flush with the top surface of the hollow area. The size of the heating seat 32 is smaller than the fork front tip. A temperature sensor 33 is installed on the heating seat 32 to preheat the fork front tip to 50-80°C before cutting, thereby reducing the thermal stress during cutting. During the cutting process, preheating can reduce the temperature difference between the cutting area and the non-cutting area, thereby reducing the thermal stress caused by uneven thermal expansion and contraction, effectively reducing fork front fork deformation, and thus improving the cutting quality.

[0023] For the above scheme, please refer to the appendix. Figure 1 As shown, the fixing part 4 includes a mounting bracket 41, which is mounted on the grille 13. An adjusting screw 42 is vertically threaded onto the mounting bracket 41, and a crank 43 is connected to the top of the adjusting screw. A pressure seat 44 is rotatably connected to the bottom of the adjusting screw 42, and a rubber pad 45 is provided on the bottom surface of the pressure seat 44. In use, by adjusting the screw 42 and the mounting bracket 41 through the threaded transmission, the crank 43 can be turned to control the lifting and lowering of the pressure seat 44, so that the rubber pad 45 on the bottom surface of the pressure seat 44 can flexibly fit the surface of the forklift fork, thus realizing the quick fixing of the forklift fork.

[0024] For the above scheme, please refer to the appendix. Figure 2 As shown, the guide part 5 includes a mounting base 51, on which a flame cutting gun 2 is mounted. Two vertical plates 52 are also vertically slidably mounted on the mounting base 51, and the vertical plates 52 are fixed in position by locking bolts 53 located on the side of the mounting base 51. A connecting ring 54 is connected to the top of the two vertical plates 52, and ball bearings 55 are installed at the bottom of both vertical plates 52. In use, the height of the vertical plates 52 can be flexibly adjusted and fixed according to the size of the forklift fork and the cutting requirements by using the locking bolts 53 on the side of the mounting base 51, so as to adapt to the position requirements of the flame cutting gun 2 under different working conditions. During operation, the ball bearings 55 contact the forklift fork, which can reduce friction with the surface of the forklift fork, allowing the guide part 5 to move smoothly along the surface of the forklift fork, ensuring that the flame cutting gun 2 maintains a fixed height and a stable cutting trajectory during the cutting process, thereby improving the cutting accuracy and consistency.

[0025] In addition, considering that rapid cooling after cutting will increase the shrinkage stress of the forklift fork, therefore, refer to the attached... Figure 3 and attached Figure 4As shown, a slow-cooling section 6 is installed on the grille 13 so that after cutting, the slow-cooling section 6 can cover the tip of the forklift fork to slow down the cooling rate, reduce shrinkage stress, and avoid additional stress caused by forced cooling. Specifically, the slow-cooling section 6 includes an outer box 61, which is disposed on the grille 13 and has one side open for accessing the tip of the forklift fork. An asbestos cloth 62 is provided inside the outer box 61 so that the combination of the outer box 61 and the asbestos cloth 62 can achieve slow cooling of the forklift fork after cutting, effectively reducing the stress caused by rapid cooling and shrinkage of the forklift fork, and preventing deformation or cracks caused by excessive temperature difference.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
