Positioning is performed according to the powder spraying line and the projection point, and the partition is assembled on the lower wing plate. During assembly, the space position of the partition is determined by a plumb bob and elevation measurement, and the plumb bob is made to coincide with the projection point of the horizontal position of the top end point of the partition.

When assembling the partition, the partition is positioned through the powder spray line on the lower wing plate and one end point of the upper inner partition. During assembly, the spatial position is determined by plumbing and measuring the elevation. The plumb bob determines that the horizontal position of the top end point of the partition coincides with the projection point. The partition elevation is measured and controlled by a level to ensure the accuracy of the installation position of the partition. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example Refer to the attached drawings of the specification, such as Figure 1-Figure 9 As shown, a bending and torsion box manufacturing device and a bending and torsion box manufacturing method proposed in the present application are used to process such a bending and torsion box 2, wherein the bending and torsion box 2 comprises a lower wing plate 21, an upper wing plate 24 and two web plates 23, wherein the lower wing plate 21 is a bending and torsion member. The upper wing plate 24 is located above the lower wing plate 21 and is arranged corresponding to the lower wing plate 21. The web plates 23 are located on both sides of the lower wing plate 21, and the upper and lower ends of the web plates 23 are respectively connected to the edges of the lower wing plate 21 and the upper wing plate 24, and the ends of the web plates 23 are flush with the lower wing plate 21. A plurality of spaced partition plates 22 are also arranged inside the bending and torsion box 2, and a through hole 221 is arranged in the center of the partition plates 22.

[0031] The manufacturing device for processing the bending-torsion box 2 comprises a plurality of tire frames 1, on which the bending-torsion box 2 is placed for processing. The tire frame 1 comprises a crossbeam 11, which is a square structure as a whole, and comprises a movable plate layer 111, a buffer layer 112, a leaf spring 113 and a filling layer 114 from top to bottom.

[0032] The movable plate layer 111 includes a plurality of movable plates 1114. Figure 6For example, the sides of the front and rear surfaces of the movable plate 1114 are penetrated with a first through hole, and a movable first pin 1111 is inserted into the first through hole, and the movable plate 1114 can rotate around the first pin 1111. In order to tie multiple movable plates 1114 into a movable plate layer 111, two parallel binding ropes 1112 are arranged in front and behind the movable plate layer 111, and each binding rope 1112 is spaced apart with multiple round holes, and both ends of the first pin 1111 simultaneously pass through the round holes arranged at corresponding positions on the two parallel binding ropes 1112 to form the movable plate layer 111. Further, the binding rope 1112 can be made of nylon rope, and in order to prevent the first pin 1111 from slipping out of the round hole, the first pin 1111 can be a stepped shaft, and the first round hole and the first pin 1111 can be fixed by gluing. At this point, multiple movable plates 1114 are arranged in a row to form the movable plate layer 111. When the bending-torsion box 2 contacts the movable plate layer 111, the movable plate 1114 thereon is subjected to the box pressure, and the movable plate 1114 can rotate around the first latch 1111 at a certain angle. During the downward pressing process of the movable plate layer 111, the movable plate 1114 thereon can better fit the shape of the bending-torsion box 2, thereby ensuring the fit between the bending-torsion box 2 and the crossbeam 11. Furthermore, the width of the movable plate 1114 can be appropriately adjusted according to actual production needs. According to the principle of differentiation, the more the number of movable plates 1114, the closer the shape of the movable plate layer 111 is to the shape of the bending-torsion box 2 itself.

[0033] The material of the buffer layer 112 is sponge. The buffer layer 112 is only provided with steel plates on the left and right surfaces. No steel plates are provided on the front and rear surfaces and the upper and lower surfaces of the buffer layer 112. The two ends of the binding rope 1112 are fixedly connected to the upper surfaces of the steel plates on the left and right sides of the buffer layer 112. When the movable plate 1114 is rotated by the pressure of the bending and torsion box 2, the buffer layer 112 is affected by the box and lowers its height as the box is pressed down. According to the different shapes of the boxes at different positions, the buffer layer 112 is subjected to different pressures. Finally, the buffer layer 112 and the movable plate layer 111 jointly form a crossbeam 11 that fits the shape of the bending and torsion box 2.

[0034] Steel plates are arranged on the surrounding surfaces of the leaf spring 113, wherein the steel plates on the left and right surfaces are integrally welded with the steel plates on the left and right sides of the buffer layer 112. Second through holes are arranged on the left and right sides of the top of the leaf spring 113, and second plugs 1131 are inserted into the second through holes. The plugs 1131 are fixedly connected to the second through holes. Specifically, the second through holes and the second plugs 1131 can be interference fit. The two ends of the second plug 1131 penetrate and fix the steel plates on the front and rear surfaces. After the second plug 1131 passes through the steel plates on the front and rear surfaces, it can be welded at the position in contact with the steel plates, so that the second plug 1131 is fixed between the steel plates. In order to leave enough space for the buffer layer 112 to descend, the height of the steel plates around the leaf spring 113 is higher than the top surface of the leaf spring 113 and lower than the top surface of the buffer layer 112.

[0035] The filling layer 114 is made of foam plastic or rubber, and steel plates are arranged on the surface and bottom of the filling layer 114. The steel plates surrounding the filling layer 114 are integrally welded with the steel plates surrounding the leaf spring 113. Through the further deformation of the leaf spring 113 and the filling layer 114, the cross beam 11 can further adapt to the shape of the bending and torsion box 2 while providing support for the bending and torsion box 2.

[0036] In addition, the tire frame 1 also includes support columns 12. The number of support columns 12 can be two, and the cross beam 11 is located between the two support columns 12, that is, the left and right ends of the cross beam 11 are respectively welded to the opposite surfaces of the two support columns 12. The number of support columns 12 can also be two or more, in which case multiple support columns 12 are welded under the cross beam 11, so that the support columns 12 generate an upward supporting force on the cross beam 11. The support columns 12 are supported on the ground.

[0037] When the number of support columns 12 is two or more, a stopper 13 is protruding from the top right side of the crossbeam 11. At this time, fixed plates 1113 parallel to the bottom surface of the crossbeam 11 are arranged on both sides of the movable plate layer 111. The edges of the fixed plates 1113 are welded and fixed to the steel plates on both sides of the crossbeam 11, and the stopper 13 is fixed to the fixed plate 1113 on the right side. Since there is no obstruction on both sides of the crossbeam 11 at this time, when the bending and torsion box 2 is placed on the crossbeam 11, it is easy to move horizontally. By arranging the stopper 13 at one end of the crossbeam 11, the distance of the box moving horizontally on the crossbeam 11 can be reduced.

[0038] Based on the above, the processing of the bending-torsion box 2 also includes the following steps: S100, set the tire frame 1 according to the given coordinates in the drawing. The distance between adjacent tire frames 1 is less than or equal to 1000 mm, and the height of the tire frame 1 above the ground is greater than or equal to 500 mm. At the same time, the installation space of the corbel should be considered.

[0039] S200, assembling the lower wing panel 21: The lower wing panel 21 is pre-set with a positioning line. The lower wing panel 21 with the positioning line is placed on the tire frame 1, and the shape of the lower wing panel 21 is adjusted to control the fit between the lower wing panel 21 and the tire frame 1. The shape of the lower wing panel 21 is adjusted by combining flame spraying with mechanical methods. The specific process is as follows: The lower wing panel 21 is heated by flame, and during the heating process, pressure is applied to the lower wing panel 21 to change the shape of the lower wing panel 21, and the fit between the lower wing panel 21 and the tire frame is controlled to be 0-2mm. During the heating process of the lower wing panel 21, a force is applied to the lower wing panel 21 by at least one of a weight, a jack, and a gourd. During the process of adjusting the shape of the lower wing panel 21 by combining flame spraying with mechanical methods, a pad is set below the required adjustment position of the lower wing panel 21. The pad is used to ensure that the lower wing panel 21 has enough space when deformed.

[0040] S300, assembling the partition: pre-set the powder spraying line on the lower wing plate 21 for the partition 22, pre-set the projection point on the lower wing plate 21 or the tire frame 1 for the top end point of the partition 22, and assemble the partition 22 on the lower wing plate 21 according to the powder spraying line and the projection point. During assembly, the spatial position of the partition 22 is determined by the plumb bob and the elevation measurement. The specific process is as follows: the horizontal position of the top end point of the partition 22 is determined to coincide with the projection point by the plumb bob, and the elevation of the partition 22 is measured and controlled by the level meter.

[0041] S400, assembling the webs 23 on both sides: using the partition 22 and the lower wing plate 21 as the positioning reference, positioning welding is performed after the webs 23, the partition 22 and the lower wing plate 21 are assembled with each other. After welding, the box size is inspected, and after the size is qualified, the webs 23, the partition 22 and the lower wing plate 21 are bottom welded, and then separated from the tire frame for welding.

[0042] S500, assembling the upper wing plate 24: After the web plate 23 is welded, assemble the upper wing plate 24, which is assembled on the tire frame 1. Before assembling the upper wing plate 21, calibrate the bending and torsion box 2 on the tire frame 1, and ensure that the fit between the two ends of the box and the tire frame 1 is less than or equal to 2mm, and the fit between the other parts of the lower wing plate 21 and the tire frame 1 is less than or equal to 4mm.

[0043] When welding the main weld of the box, follow the following sequence: ① Use CO2 gas shielded welding to weld the weld between the upper wing plate and the web of the box to 1 / 3 of the groove depth, and turn the box over; ② Use CO2 gas shielded welding and submerged arc welding to weld the weld between the lower wing plate and the web of the box body to 1 / 2 of the groove depth, and turn the box over; when welding, use the method of first performing gas shielded welding for base coating and then covering with submerged arc welding; ③. Use submerged arc welding to weld the remaining depth of the groove of the weld between the upper wing plate and the web of the box body, and turn the box over; ④. Use submerged arc welding to weld the remaining depth of the groove of the weld between the lower wing plate and the web.
