Description

Technical Field

[0001] This invention relates to the field of bogie long and irregularly shaped parts processing technology, and in particular to a method for improving the deformation of long and irregularly shaped bogie parts cut by flame cutting. Background Technology

[0002] Flame cutting is commonly used for cutting thick carbon steel plates. Its cutting equipment and costs are relatively low, and it produces little pollution. It is widely used in the manufacture of bogie parts for railway vehicles.

[0003] Due to the internal stress of the raw materials and the effects of thermal cutting, flame-cut parts can experience severe deformation when they are long and asymmetrical. Current methods include changing the cutting equipment, increasing peripheral compensation, or using bridging techniques, which increases cutting, blanking, and machining costs. See also Figure 1 As shown, the "bridging" cutting method connects the cut part to the base material, but it cannot automatically detach from the waste material. The entire board needs to be hoisted, which is inconvenient for subsequent operations and poses a safety risk.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a method to improve the deformation of long and irregularly shaped bogie components cut by flame cutting. Summary of the Invention

[0005] The purpose of this invention is to provide a method for improving the deformation of long and irregularly shaped bogie parts cut by flame cutting, thereby limiting the occurrence of deformation problems in flame-cut parts, reducing production costs, and increasing equipment production capacity.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention provides a method for improving the deformation of long and irregular bogie components cut by flame cutting, wherein the method comprises setting multiple limiting structures around the periphery of the long and irregular bogie component to be flame cut.

[0009] Furthermore, the limiting structure includes:

[0010] The cutting section connecting to the long, irregularly shaped bogie component; and

[0011] A limiting portion is formed at the end of the cut portion away from the end of the long, irregularly shaped bogie component;

[0012] The cross-sectional dimension of the limiting part is larger than that of the cutting part, and the limiting structure can be manually cut off the cutting part to achieve separation from the long and irregular bogie component.

[0013] Furthermore, the limiting structure is arranged at least near the end of the long, irregularly shaped bogie component and at the starting point where the component offset occurs during flame cutting.

[0014] Furthermore, at least one of the limiting structures is arranged in each section of the long, irregularly shaped bogie component.

[0015] Furthermore, the long, irregularly shaped bogie component includes:

[0016] Middle section;

[0017] The end sections located at both ends of the long, irregularly shaped bogie component along its length; and

[0018] A transition section formed between the intermediate section and the end section;

[0019] The transition section is divided into an arc-shaped transition section and a planar transition section.

[0020] Furthermore, the limiting structure is provided on any one or both end segments of the long, irregularly shaped bogie component;

[0021] And the number of the limiting structures located at the end segment is at least one.

[0022] Furthermore, each of the planar transition sections of the long, irregularly shaped bogie component is provided with the limiting structure, and the number of limiting structures at that location is at least one.

[0023] Furthermore, the arc-shaped transition section of the long, irregularly shaped bogie component can be provided with the limiting structure.

[0024] In the above technical solution, the method for improving the deformation of long and irregularly shaped bogie components provided by the present invention has the following beneficial effects:

[0025] The method of the present invention limits the displacement and deformation of parts during the hot cutting process by adding a limiting structure to the long and irregular bogie parts, thus ensuring the quality of the flame-cut parts. After flame cutting, the limiting structure can be manually cut off to improve the utilization rate of the equipment without affecting the utilization rate of raw materials.

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] See Figures 2 to 6 As shown;

[0039] This embodiment provides a method for improving the deformation of long and irregular bogie parts cut by flame cutting. The method involves setting multiple limiting structures 2 around the long and irregular bogie parts 1 to be flame cut.

[0040] The limiting structure 2 is arranged on the side where the cutting gun starts cutting, according to the cutting path.

[0041] The limiting structure 2 in this embodiment includes:

[0042] The cutting section 201 connected to the long, irregularly shaped bogie component 1; and

[0043] A limiting part 202 is formed at the end of the cutting part 201 away from the end of the long and irregular bogie piece 1;

[0044] The cross-sectional dimension of the limiting part 202 is larger than that of the cutting part 201. The limiting structure 2 can be manually cut off to separate it from the long and irregular bogie component 1.

[0045] Specifically, analysis of the cutting parameter data for the long, irregularly shaped bogie component 1 revealed that the twisting was less on one side of the initial cutting point and more on the other, exhibiting a "the more it cuts, the more it deviates" phenomenon, and the starting position of the twisting followed a predictable pattern. Therefore, in this embodiment, the limiting structure 2 is added to the side of the initial cutting point of the cutting gun according to the cutting path.

[0046] Secondly, the limiting structure 2 in this embodiment is divided into the cutting part 201 and the limiting part 202 mentioned above. The limiting part 202 is larger than the cutting part 201. The cutting part 201 is a connecting rod-shaped structure. The limiting part 202 is integrally formed with the long and irregular bogie part 1 through the cutting part 201.

[0047] Based on the analysis of the cutting parameter data of the long and irregular bogie component 1, the arrangement position and quantity of the limiting structure 2 in this application are determined. Specifically, the limiting structure 2 is arranged at least near the end of the long and irregular bogie component 1 and at the starting point where the part offset occurs during flame cutting of the long and irregular bogie component 1.

[0048] Preferably, in this embodiment, at least one limiting structure 2 is arranged in each section of the bogie irregular long component 1.

[0049] First, the structure of the long, irregularly shaped bogie component 1 involved in this embodiment is further described, specifically: the long, irregularly shaped bogie component 1 in this embodiment includes:

[0050] Middle section 101;

[0051] End sections 102 located at both ends of the length of the long, irregularly shaped bogie component 1; and

[0052] A transition section formed between the intermediate section 101 and the end section 102;

[0053] The transition section is divided into an arc-shaped transition section 103 and a planar transition section 104.

[0054] In this embodiment, any one end segment 102 or both end segments 102 of the long and irregular bogie component 1 are provided with a limiting structure 2; and the number of limiting structures 2 located on the end segment 102 is at least one.

[0055] Preferably, in this embodiment, any planar transition section 104 of the long and irregular bogie component 1 is provided with a limiting structure 2, and the number of limiting structures 2 at that location is at least one.

[0056] Preferably, the arc-shaped transition section 103 of the long bogie component 1 in this embodiment can be provided with a limiting structure 2.

[0057] The arrangement position and quantity of the limiting structure 2 for the aforementioned long and irregular bogie components can be optimized according to actual conditions without affecting the utilization rate of raw materials.

[0058] In the above technical solution, the method for improving the deformation of long and irregularly shaped bogie components provided by the present invention has the following beneficial effects:

[0059] The method of the present invention adds a limiting structure 2 to the long and irregular bogie part 1 to limit the displacement and deformation of the part during the hot cutting process, thereby ensuring the quality of the flame-cut parts. After flame cutting, the limiting structure 2 can be manually cut off to improve the equipment utilization rate without affecting the utilization rate of raw materials.

[0060] After cutting, the cut parts and waste materials can be separated without affecting subsequent operations, without causing safety risks, and improving work efficiency.

[0061] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
