Description

Technical Field

[0001] This invention relates to the field of ore open wagon technology, and more specifically, to a method for processing the body of an open wagon. Background Technology

[0002] Ore open wagons are a common type of railway freight car, mainly used for transporting goods such as ore and mineral powder. The underframe of the ore open wagon is the main load-bearing component, and the underframe is connected to the end walls and side walls to form the space for carrying goods.

[0003] In related technologies, the underframe, end walls, and side walls are manufactured separately. When assembling ore open wagons, the end walls are first positioned and welded to the underframe. Then, the side walls are erected on the underframe, fitting snugly against the end walls. Using the end wall height as a reference, and considering that the side wall's support columns and side posts have a pre-cut allowance of at least 20mm during manufacturing, the support columns and side posts on the side walls need to be precisely cut. Specifically, the height difference between each support column and side post on the side wall and the corresponding support beam and crossbeam on the underframe is measured, and cutting lines are drawn. The side walls are then disassembled and placed on a platform, and excess material from the support columns and side posts is removed, thereby adjusting the side wall height to match the end wall height.

[0004] However, the related technology involves pre-reserving the cutting allowance for the side wall's support columns and side columns, and then welding the side wall to the base frame. Determining the height of the support columns and side columns based on the height of the end wall requires repeated cutting, resulting in numerous processing steps for the side wall, wasting a lot of labor costs, reducing work efficiency, and affecting production efficiency. Summary of the Invention

[0005] This invention provides a method for processing open wagon bodies to solve the problem in related technologies where the process involves pre-reserving the cutting allowance for the sidewall's bolsters and side pillars, welding the sidewalls to the underframe, and then repeatedly cutting the bolsters and side pillars based on the height of the end walls. This results in numerous processing steps for the sidewalls, wasting a lot of manpower and reducing work efficiency.

[0006] This invention provides a method for processing a convertible car body. The method includes: positioning and clamping a first beam group using a first positioning beam, forming a first support structure that is high in the middle and low at both ends; the first beam group includes two bolster beams and multiple crossbeams disposed between the two bolster beams; positioning and clamping a second beam group using a second positioning beam, making the second beam group structurally identical to the first beam group; welding the first beam group clamped by the first positioning beam and the second beam group clamped by the second positioning beam to both sides of a center beam to form a base frame; removing the first and second positioning beams; obtaining the distance between the bottom surface of the core plate of the bolster beam of the first beam group and the top surface of the bolster beam, and the distance between the bottom surface of the core plate of the bolster beam of the first beam group and the top surface of each crossbeam; and determining the distance between the bottom surface of the core plate of the bolster beam and the top surface of the bolster beam based on the distance between the bottom surface of the core plate of the bolster beam and the top surface of each crossbeam; and determining the distance between the bottom surface of the core plate of the bolster beam and the top surface of the bolster beam. The design height of the bolster pillars is determined by the distance between the top surfaces and the design height of the open wagon body. The design height of multiple side pillars is determined based on the distance between the bottom surface of the bolster beam's core plate and the top surface of each crossbeam, as well as the design height of the open wagon body. Two bolster pillars and multiple side pillars are fabricated according to their design heights. The two bolster pillars and multiple side pillars are positioned to form a second support structure with a higher center and lower ends, and welded to the side plates to form a first side wall. A second side wall with the same structure as the first side wall is fabricated. The two bolster beams of the first beam group are welded to the two bolster pillars of the first side wall, and the multiple crossbeams of the first beam group are welded to the multiple side pillars of the first side wall. The second beam group is welded to the second side wall. Two end walls are fabricated and connected to the first side wall, the second side wall, and the underframe, respectively.

[0007] Furthermore, the step of using the first positioning beam to position and clamp the first beam group, and making the first beam group form a first support structure that is high in the middle and low at both ends, the first beam group including two bolster beams and multiple crossbeams set between the two bolster beams includes: erecting the first positioning beam on the two bolster beams and multiple crossbeams; setting multiple pads of different thicknesses between the first positioning beam and the two bolster beams and multiple crossbeams, and clamping the first positioning beam with the two bolster beams and multiple crossbeams respectively by multiple clamps.

[0008] Furthermore, the thickness of the multiple pads gradually decreases from the center of the base frame towards both ends.

[0009] Further, the step of positioning the two bolster columns and multiple side columns to form a second support structure with a high center and low ends on the bottom surface, and welding it to the side plate to form the first side wall includes: placing the side plate of the first side wall on a tooling table, on which two bolster column positioning components and multiple side column positioning components are set according to the design height of the bolster columns and multiple side column positioning components. The two bolster column positioning components and multiple side column positioning components are located on the same side of the side plate, and the distance between the positioning surface of the two bolster column positioning components and the positioning surface of the multiple side column positioning components and the bottom edge of the side plate gradually increases from the center to both ends; fitting the side columns and bolster columns to the side plate, fitting the lower surface of the side columns to the side column positioning components, fitting the lower surface of the bolster columns to the bolster column positioning components, and welding the two bolster columns and multiple side columns to the side plate respectively.

[0010] Furthermore, the steps for processing the two end walls include: placing the end column, end plate, cross band, and upper beam into the clamping fixture using a clamping fixture, clamping the end wall using the clamping fixture, and welding the end column, cross band, and upper beam to the end plate to obtain the end wall.

[0011] Furthermore, the clamping fixture includes a first U-shaped clamping arm and a second U-shaped clamping arm, and the end plate, cross belt and upper end beam are all clamped within the first U-shaped clamping arm and the second U-shaped clamping arm.

[0012] Furthermore, after processing two end walls and connecting the two end walls to the first side wall, the second side wall, and the underframe respectively, the open wagon body processing method further includes: eliminating the assembly gaps between the first and second side walls and the underframe, and eliminating the assembly gaps between the first and second side walls and the two end walls.

[0013] Further, the steps of processing two end walls and connecting the two end walls to the first side wall, the second side wall, and the base frame respectively include: setting telescopic rods between the bolster columns and side columns of the first side wall so that the outer edges of the two bolster columns are flush with the outer edges of the bolster beams of the first beam group, and the outer edges of the multiple side columns are flush with the outer edges of the crossbeams of the first beam group; setting telescopic rods between the bolster columns and side columns of the second side wall so that the outer edges of the two bolster columns are flush with the outer edges of the bolster beams of the second beam group, and the outer edges of the multiple side columns are flush with the outer edges of the crossbeams of the second beam group.

[0014] Furthermore, the step of eliminating the assembly gap between the first and second side walls and the base frame includes: clamping the upper end of the first side wall with the first clamping jaw of the clamping device, clamping the bolster or crossbeam of the first beam group with the second clamping jaw of the clamping device, the first and second clamping jaws being connected by a screw thread, and rotating the screw thread to reduce the gap between the first side wall and the base frame; clamping the upper end of the second side wall with the first clamping jaw of the clamping device, clamping the bolster or crossbeam of the second beam group with the second clamping jaw of the clamping device, and rotating the screw thread to reduce the gap between the second side wall and the base frame.

[0015] Furthermore, the step of eliminating the assembly gaps between the first sidewall and the second sidewall and the two end walls also includes: reducing the gaps between the first sidewall and the second sidewall and the two end walls by pushing the first sidewall or the second sidewall with the push rod of the gap-locking device.

[0016] Applying the technical solution of this invention, the open wagon body processing method includes using a first positioning beam to position and clamp a first beam assembly, thereby forming a first support structure with a high middle and low ends. The first beam assembly includes two bolster beams and multiple crossbeams disposed between the two bolster beams. The first positioning beam can simultaneously clamp the two bolster beams and the multiple crossbeams, so that when welding the first beam assembly to the middle beam, the first positioning beam can play a positioning and clamping role, avoiding the problem of deformation of the first beam assembly due to thermal expansion and contraction during welding, ensuring that the first beam assembly forms a first support structure, thereby ensuring that the first beam assembly meets production requirements and can play a supporting role (the deflection of the first beam assembly meets the requirements during subsequent load-bearing). A second positioning beam is used to position and clamp a second beam assembly, ensuring that the second beam assembly is clamped and positioned under the action of the second positioning beam, thereby forming a second beam assembly with the same structure as the first beam assembly, ensuring that the second beam assembly also meets production requirements and can also play a supporting role. Furthermore, the first beam group and the second beam group are welded to both sides of the middle beam to facilitate the formation of the base frame. By using the first positioning beam and the second positioning beam to position and clamp the first beam group and the second beam group respectively during the welding of the base frame, the deformation problem that would occur when the first beam group and the second beam group are welded to the middle beam is avoided.

[0017] Next, the first and second positioning beams are removed. The design height of the bolster pillar is determined by obtaining the distance between the bottom surface of the core plate of the bolster beam in the first beam group and the top surface of the bolster beam, as well as the design height of the open wagon body. The design heights of multiple side pillars are determined by using the distance between the bottom surface of the core plate of the bolster beam in the first beam group and the top surface of each crossbeam, as well as the design height of the open wagon body. Specifically, the design height of the bolster pillar is obtained by subtracting the distance between the bottom surface of the core plate of the bolster beam and the top surface of the bolster beam from the design height of the open wagon body. The design height of each side pillar is obtained by subtracting the distance between the bottom surface of the core plate of the bolster beam and the top surface of each crossbeam from the design height of the open wagon body. This ensures precise machining of the bolster pillars and side pillars, enabling the bolster pillars and bolster beams to be matched and installed, and the side pillars and crossbeams to be matched and installed.

[0018] Next, the two produced bolsters and multiple side columns are positioned to form a second support structure, higher in the middle and lower at both ends. This second support structure is then welded to the side plates to form the first side wall. A second side wall with the same structure as the first side wall is then constructed. The two bolsters of the first side wall are welded to the two bolster beams of the first beam group, and the multiple crossbeams of the first beam group are welded to the multiple side columns of the first side wall, ensuring that the first side wall can be connected to the underframe. Simultaneously, the second side wall is welded to the second beam group. After the first and second side walls are welded to the underframe, the end walls are processed to connect the two end walls, the first side wall, the second side wall, and the underframe, thus forming the open wagon body.

[0019] By using the above processing method, the first and second positioning beams can play a positioning and clamping role when welding the first and second beam groups to the middle beam, respectively, to prevent deformation during the welding of the base frame. This allows the first and second beam groups on the base frame to form a structure that is high in the middle and low at both ends, ensuring that the deflection of the first and second beam groups meets the requirements when the base frame can support the storage of goods. After welding the underframe, the design height of the bolster is obtained by subtracting the distance between the bottom surface of the bolster core and the top surface of the bolster beam from the design height of the open wagon body. Similarly, the design height of the side pillars can be obtained, thus enabling precise machining of the first and second side walls. After machining, the first and second side walls are welded to the underframe. After welding, the two end walls are welded to the first side wall, the second side wall, and the underframe respectively to form the open wagon body. This eliminates the need to reserve process cutting allowances for the bolsters and side pillars of the side walls, and eliminates the need for repeated cutting of the height of the bolsters and side pillars of the side walls, reducing the machining steps of the first and second side walls and improving the work efficiency of the open wagon body machining.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 7As shown, an embodiment of the present invention provides a method for processing a wagon body, the method comprising:

[0041] The first positioning beam 10 is used to position and clamp the first beam group 20, so that the first beam group 20 forms a first support structure that is high in the middle and low at both ends. The first beam group 20 includes two bolster beams 21 and multiple crossbeams 22 disposed between the two bolster beams 21.

[0042] The second positioning beam is used to position and clamp the second beam group 30, so that the second beam group 30 has the same structure as the first beam group 20.

[0043] The first beam group 20, which is held by the first positioning beam 10, and the second beam group 30, which is held by the second positioning beam, are welded to both sides of the middle beam to form the base frame 40.

[0044] Remove the first positioning beam 10 and the second positioning beam;

[0045] Obtain the distance between the bottom surface of the core plate of the bolster beam 21 of the first beam group 20 and the top surface of the bolster beam 21, as well as the distance between the bottom surface of the core plate of the bolster beam 21 of the first beam group 20 and the top surface of each crossbeam 22.

[0046] The design height of the bolster pillar is determined based on the distance between the bottom surface of the core plate of the bolster beam 21 and the top surface of the bolster beam 21 and the design height of the open wagon body. The design height of multiple side pillars is determined based on the distance between the bottom surface of the core plate of the bolster beam 21 and the top surface of each crossbeam 22 and the design height of the open wagon body.

[0047] Two pillow columns 51 and multiple side columns 52 are processed according to the design height of the pillow column and the design height of multiple side columns.

[0048] Two pillow columns 51 and multiple side columns 52 are positioned to form a second support structure with a high middle and low ends on the bottom surface, and are welded to the side plate 53 to form a first side wall 50.

[0049] A second sidewall with the same structure as the first sidewall 50 is fabricated;

[0050] Weld the two bolster beams 21 of the first beam group 20 to the two bolster columns 51 of the first side wall 50 accordingly, and weld the multiple cross beams 22 of the first beam group 20 to the multiple side columns 52 of the first side wall 50 accordingly.

[0051] Weld the second beam group 30 to the corresponding second side wall;

[0052] Two end walls 60 are processed and connected to the first side wall 50, the second side wall and the base frame 40 respectively.

[0053] Using the above steps, the open wagon body processing method includes using a first positioning beam 10 to position and clamp the first beam assembly 20, thereby making the first beam assembly 20 form a first support structure that is high in the middle and low at both ends. The first beam assembly 20 includes two bolster beams 21 and multiple crossbeams 22 disposed between the two bolster beams 21. The first positioning beam 10 can clamp the two bolster beams 21 and the multiple crossbeams 22 at the same time, so that when the first beam assembly 20 is welded to the middle beam, the first positioning beam 10 can play a positioning and clamping role, avoiding the problem of deformation of the first beam assembly 20 due to thermal expansion and contraction during welding, ensuring that the first beam assembly 20 forms a first support structure, thereby ensuring that the first beam assembly 20 meets production requirements and can play a supporting role (the deflection of the first beam assembly meets the requirements when bearing loads in the future). The second positioning beam is used to position and clamp the second beam group 30, ensuring that it is clamped and positioned. This creates a second beam group 30 with the same structure as the first beam group 20, meeting production requirements and providing support. The first beam group 20 and the second beam group 30 are welded to both sides of the middle beam to form the base frame 40. During the welding of the base frame 40, the first positioning beam 10 and the second positioning beam clamp the first beam group 20 and the second beam group 30 respectively, preventing deformation that could occur when they are welded to the middle beam.

[0054] Next, the first positioning beam 10 and the second positioning beam are removed. The design height of the bolster pillar is determined by obtaining the distance between the bottom surface of the core plate of the bolster beam 21 of the first beam group 20 and the top surface of the bolster beam 21, as well as the design height of the open wagon body. The design heights of multiple side pillars are determined by using the distance between the bottom surface of the core plate of the bolster beam 21 of the first beam group 20 and the top surface of each crossbeam 22, as well as the design height of the open wagon body. Specifically, the design height of the bolster pillar is obtained by subtracting the distance between the bottom surface of the core plate of the bolster beam 21 and the top surface of each crossbeam 22 from the design height of the open wagon body. The design height of each side pillar is obtained by subtracting the distance between the bottom surface of the core plate of the bolster beam 21 and the top surface of each crossbeam 22 from the design height of the open wagon body. This ensures that the bolster pillar 51 and the side pillar 52 are precisely machined, so that the bolster pillar 51 and the bolster beam 21 can be matched and installed, and the side pillar 52 and the crossbeam 22 can be matched and installed.

[0055] Next, the two produced bolster columns 51 and multiple side columns 52 are positioned to form a second support structure with a higher center and lower ends on the bottom surface. This second support structure is then welded to the side plate 53 to form the first side wall 50. A second side wall with the same structure as the first side wall 50 is also constructed. The two bolster columns 51 of the first side wall 50 are welded to the two bolster beams 21 of the first beam group 20, and the multiple crossbeams 22 of the first beam group 20 are welded to the multiple side columns 52 of the first side wall 50, ensuring that the first side wall 50 can be connected to the underframe 40. Simultaneously, the second side wall is welded to the second beam group 30. After welding the first and second side walls to the underframe 40, the end walls 60 are processed to connect the two end walls 60, the first side wall 50, the second side wall, and the underframe 40 to form the open wagon body.

[0056] By using the above processing method, the first positioning beam 10 and the second positioning beam can play a positioning and clamping role when the first beam group 20 and the second beam group 30 are welded to the middle beam respectively, so as to avoid deformation when welding the base frame 40. This allows the first beam group 20 and the second beam group 30 on the base frame 40 to form a structure that is high in the middle and low at both ends, ensuring that the deflection of the first beam group 20 and the second beam group 30 meets the requirements when the base frame 40 can support the storage of goods and deform. After welding the underframe 40, the design height of the bolster pillar is obtained by subtracting the distance between the bottom surface of the core plate of the bolster beam 21 and the top surface of the bolster beam 21 from the design height of the open wagon body. Similarly, the design height of the side pillars can be obtained, thereby enabling precise processing of the first side wall 50 and the second side wall. After processing, the first side wall 50 and the second side wall are welded to the underframe 40. After welding, the two end walls 60 are welded to the first side wall 50, the second side wall, and the underframe 40 respectively to form the open wagon body. This eliminates the need to reserve the process cutting amount for the bolster pillars 51 and the side pillars 52 of the side walls, and eliminates the need to repeatedly cut the height of the bolster pillars 51 and the side pillars 52 of the side walls, reducing the processing steps of the first side wall 50 and the second side wall, and improving the work efficiency of processing the open wagon body.

[0057] It should be noted that by using the first positioning beam 10 to position and clamp the first beam group 20, the ends of the bolster beam and crossbeam of the first beam group 20 can be rigidly fixed, reducing the impact of welding deformation on the position of the bolster beam and crossbeam, thereby ensuring the position of the bolster beam and crossbeam welded to the middle beam and the process deflection requirements.

[0058] like Figure 3 and Figure 4 As shown, the steps of using the first positioning beam 10 to position and clamp the first beam group 20, thereby forming a first support structure that is high in the middle and low at both ends, and the first beam group 20 including two bolster beams 21 and multiple crossbeams 22 disposed between the two bolster beams 21 include:

[0059] The first positioning beam 10 is erected on two sleeper beams 21 and multiple cross beams 22;

[0060] Multiple pads of different thicknesses are set between the first positioning beam 10 and the two bolster beams 21 and multiple crossbeams 22, and multiple clamps are used to clamp the first positioning beam 10, the two bolster beams 21 and multiple crossbeams 22 respectively.

[0061] By employing the above steps, the first positioning beam 10 is erected on two bolster beams 21 and multiple crossbeams 22, thereby enabling the first positioning beam 10 to serve as a positioning and clamping mechanism. Multiple pads of varying thicknesses are placed between the first positioning beam 10 and the two bolster beams 21 and multiple crossbeams 22, and clamps are used to clamp the first positioning beam 10, the two bolster beams 21, and multiple crossbeams 22 respectively. Through the multiple pads of varying thicknesses, it is ensured that under the action of the first positioning beam 10, the two bolster beams 21 and multiple crossbeams 22 form a first support structure that is high in the middle and low at both ends. This facilitates the first support structure to provide support (ensuring the deflection of the first beam group meets requirements during subsequent load-bearing), enabling the base frame 40 to provide support and thus meeting the production needs of the base frame 40.

[0062] In this embodiment, the thickness of the multiple pads gradually decreases from the center of the base frame 40 towards both ends. By setting multiple pads and utilizing the fact that the thickness of the pads gradually decreases from the center of the base frame 40 towards both ends, the two bolster beams 21 and the multiple crossbeams 22 can form a first support structure that is high in the middle and low at both ends under the action of the multiple pads. This can both prevent the first beam group 20 from deforming during welding and ensure that the base frame 40 can be precisely processed.

[0063] In this embodiment, the step of positioning two pillow columns 51 and multiple side columns 52 to form a second support structure with a high center and low ends on the bottom surface, and welding it with side plates 53 to form a first side wall 50 includes:

[0064] The side plate 53 of the first side wall 50 is placed on the tooling table. Two pillow column positioning parts 71 and multiple side column positioning parts 72 are set on the tooling table according to the design height of the pillow column and the design height of multiple side columns. The two pillow column positioning parts 71 and multiple side column positioning parts 72 are located on the same side of the side plate 53. The distance between the positioning surface of the two pillow column positioning parts 71 and the positioning surface of the multiple side column positioning parts 72 and the bottom edge of the side plate 53 gradually increases from the center to both ends.

[0065] Side pillars 52 and pillow pillars 51 are attached to side plates 53. The lower surface of side pillars 52 is attached to side pillar positioning parts 72, and the lower surface of pillow pillars 51 is attached to pillow pillar positioning parts 71. Two pillow pillars 51 and multiple side pillars 52 are welded to side plates 53 respectively. By adopting the above steps, by placing the side plate 53 of the first side wall 50 on the tooling table, and setting the pillow column positioning component 71 corresponding to the pillow column 51 and the side column positioning component 72 corresponding to the side column 52 on the tooling table, it is possible to use the pillow column positioning component 71 to position the pillow column 51 and the side column positioning component 72 to position the side column 52 when the side plate 53 is placed on the tooling table. This ensures that the two pillow columns 51 and the multiple side columns 52 can, under the action of the pillow column positioning component 71 and the side column positioning component 72, make the distance between the positioning surface of the multiple side column positioning component 72 and the positioning surface of the two pillow column positioning component 71 and the bottom edge of the side plate 53 gradually increase from the center to both ends, thereby forming a second support structure that is high in the middle and low at both ends. This facilitates the assembly and fixation of the first side wall 50 and also enables the positioning and connection of the first side wall 50 to the base frame 40.

[0066] It should be noted that, as Figure 6 The table shown is a tooling table provided in an embodiment of the present invention. The pillow column positioning component 71 and the side column positioning component 72 are both set on the tooling table. The pillow column positioning component 71 and the side column positioning component 72 of the tooling table are used to position the side column 52 and the pillow column 51 of the first side wall, so that the side column 52 and the pillow column 51 of the first side wall can form a second support structure. This allows the second support structure of the first side wall, which is high in the middle and low at both ends, to match the first beam group, which forms a first support structure that is high in the middle and low at both ends. This facilitates the welding and fixing of the first side wall and the first beam group.

[0067] Specifically, such as Figure 6 As shown, by setting the distance L1 between the bolster column positioning component 71 and the bottom edge of the tooling table, it is convenient to match the two bolster columns 51 with the two bolster column positioning components 71. Multiple side column positioning components 72 are set, with one side column positioning component 72 having a distance L2 between it and the bottom edge of the tooling table, and another side column positioning component 72 having a distance L3 between it and the bottom edge of the tooling table. The distance L3 between the other side column positioning component 72 and the bottom edge of the tooling table is greater than the distance L2 between the side column positioning component and the bottom edge of the tooling table, and the distance L2 between the side column positioning component and the bottom edge of the tooling table is greater than the distance L1 between the bolster column positioning component and the bottom edge of the tooling table. This facilitates the first side wall to form a second support structure that cooperates with the first support structure of the first beam group. This makes it convenient to assemble the first side wall and to position and install the side columns 52 and bolster columns 51 of the first side wall.

[0068] In this embodiment, the steps for processing the two end walls 60 include:

[0069] The end plate 62, crossband 63, and upper beam 64 are placed in a clamping fixture, and the end wall 60 is clamped using the clamping fixture. The crossband 63 and upper beam 64 are then welded to the end plate 62 to form the end wall 60. By using the above steps, the end plate 62, crossband 63, and upper beam 64 of the end wall 60 are clamped and fixed using a clamping fixture. After clamping, the end post 61 is placed on the end plate 62 for welding. In this way, during welding of the end wall 60, the clamping fixture provides a clamping effect, preventing deformation of the end wall 60 and reducing the impact of end wall 60 deformation on the assembly gap between the end plate 62 and the side plate, as well as on the overall appearance quality of the vehicle.

[0070] In this embodiment, the clamping fixture includes a first U-shaped clamping arm and a second U-shaped clamping arm. The end post 61, end plate 62, crossband 63, and upper beam 64 are all clamped within the first and second U-shaped clamping arms. By employing the above steps, the end post 61, end plate 62, crossband 63, and upper beam 64 are clamped using the first and second U-shaped clamping arms, which facilitates welding of the end wall 60 and prevents deformation of the end wall 60.

[0071] In this embodiment, when the first side wall 50 is manufactured, no pre-reserved process cutting allowance is made for the bolster and side pillar of the first side wall 50. The design height of the bolster and the design height of the side pillar are determined by converting the core plate on the bolster beam with the upper surface of the bolster beam and the upper surface of the crossbeam, respectively. Taking into account the deflection values ​​set by the bolster beam and crossbeam in the underframe, bolster positioning component 71 and side pillar positioning component 72 are set when the first side wall is assembled. In this way, while ensuring the height of the first side wall, the deflection value formed by the bolster and side pillar of the first side wall is controlled to match the deflection value formed by the bolster beam and crossbeam of the underframe.

[0072] In this embodiment, after processing two end walls 60 and connecting the two end walls 60 to the first side wall 50, the second side wall, and the underframe 40 respectively, the open wagon body processing method further includes:

[0073] Eliminate the assembly gaps between the first sidewall 50 and the second sidewall and the underframe 40, and eliminate the assembly gaps between the first sidewall 50 and the second sidewall and the two end walls 60. By adopting the above steps, eliminating the assembly gaps between the first sidewall 50 and the second sidewall and the underframe 40 ensures the welding strength between the first sidewall 50 and the second sidewall and the underframe 40, preventing weak welding that would cause the open wagon body to fail to provide support. Eliminating the assembly gaps between the first sidewall 50 and the second sidewall and the two end walls 60 also ensures the welding strength between the first sidewall 50 and the second sidewall and the two end walls 60.

[0074] It should be noted that by eliminating the assembly gaps between the first side wall 50 and the second side wall and the base frame 40, the assembly gaps between the bolster column and the bolster beam, as well as between the side column and the cross beam, are ensured to be no greater than 3mm, thereby meeting the welding strength requirements between the first side wall 50 and the base frame 40.

[0075] In this embodiment, the steps of processing two end walls 60 and connecting the two end walls 60 to the first side wall 50, the second side wall, and the base frame 40 respectively include:

[0076] By setting telescopic rods, which are set between the bolster column 51 and the side column 52 of the first side wall 50, the outer edges of the two bolster columns 51 are flush with the outer edges of the bolster beam 21 of the first beam group 20, and the outer edges of the multiple side columns 52 are flush with the outer edges of the cross beam 22 of the first beam group 20.

[0077] The telescopic rod is installed between the bolster column 51 and the side column 52 of the second side wall, so that the outer edges of the two bolster columns 51 are flush with the outer edges of the bolster beam 21 of the second beam group 30, and the outer edges of the multiple side columns 52 are flush with the outer edges of the crossbeam 22 of the second beam group 30. By using the above steps, and applying force to the bolster column 51 or the side column 52 using the telescopic rod, it is easy to align and fit the outer edges of the bolster column 51 with the outer edges of the bolster beam 21, and the outer edges of the side columns 52 with the outer edges of the crossbeam 22, thus avoiding misalignment between the bolster column 51 and the bolster beam 21, and ensuring a firm connection between the bolster column 51 and the bolster beam 21, and between the side column 52 and the crossbeam 22.

[0078] In this embodiment, the step of eliminating the assembly gaps between the first sidewall 50 and the second sidewall and the base frame 40 includes:

[0079] The first clamp of the clamping device clamps the upper end of the first side wall 50, and the second clamp of the clamping device clamps the pillow beam 21 or cross beam 22 of the first beam group 20. The first clamp and the second clamp are connected by a screw thread. The screw is rotated to reduce the gap between the first side wall 50 and the base frame 40.

[0080] The first jaw of the clamping device clamps the upper end of the second sidewall, and the second jaw clamps the bolster beam 21 or crossbeam 22 of the second beam assembly 30. Rotating the screw reduces the gap between the second sidewall and the underframe 40. By using the above steps, clamping the upper end of the first sidewall 50 with the first jaw and the bolster beam 21 or crossbeam 22 of the first beam assembly 20 with the second jaw, and rotating the screw moves the first jaw closer to the second jaw, thus eliminating the gap between the first sidewall 50 and the underframe 40 and ensuring the welding strength between them. Similarly, using the clamping device to eliminate the gap between the second sidewall and the underframe 40 ensures the welding strength of the open wagon body.

[0081] In this embodiment, the step of eliminating the assembly gaps between the first sidewall 50 and the second sidewall and the two end walls 60 further includes:

[0082] By using the push rod of the gap-clamping device to push the first sidewall 50 or the second sidewall, the gap between the first sidewall 50 and the second sidewall and the two end walls 60 is reduced. By using the above steps, by using the push rod to apply a pushing force to the first sidewall 50, the gap between the first sidewall 50 and the two end walls 60 can be reduced, avoiding a gap that is too large to allow welding.
