Description

Technical Field

[0001] The present invention relates to the technical field of motorcycles, and particularly relates to a stacking method for wing plate castings. Background Art

[0002] A casting with wing plates as shown in Figure 1 and Figure 2 has a bulge formed in the middle part. Front and rear wing plates are integrally formed on the front and rear sides of the bulge. There is a middle through hole in the center of the bulge. There are strip-shaped flanges on the edges of the middle through hole in the front and rear of the bulge. The flanges are perpendicular to the wing plates and the side surfaces of the bulge. Among the front and rear sides of the bulge, two convex columns are integrally formed on one side. The two convex columns are symmetric about the center of the bulge, and the dimension of the convex columns protruding from the side surface of the bulge exceeds the single-side width of the wing plate. Each flange is vertically connected to the outer wall of the corresponding convex column. In the middle part of the flange bulge, the convex columns are located at the lower part of the bulge; Symmetric steps are integrally formed on the left and right sides of the bulge, and the top surface of the steps is lower than the top surface of the bulge.

[0003] For this kind of casting with wing plates, because its shape is similar to a convex structure with a smaller upper part and a larger lower part, and there are wing plates protruding or convex columns protruding at the front and rear positions in the middle of the convex structure, the casting forms a special shape. It is difficult to stack this special-shaped casting during packaging, and it is easy to collapse when the special-shaped castings are gradually stacked. In addition, the length of the casting is about 2 meters, the thickness of the bulge is less than 17 cm, and the maximum height is about 0.7 meters. This kind of casting has a large length dimension and a large weight. Once it collapses, it is very dangerous. Therefore, generally it is not stacked under the premise of ensuring safety, resulting in a small number of castings transported each time and increasing the transportation cost. Summary of the Invention

[0004] The present invention aims to provide a stacking method for wing plate castings to solve the problem that the existing wing plate castings are difficult to stack gradually, resulting in high transportation costs.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A stacking method for wing plate castings requires the use of a storage tooling. The storage tooling includes at least two groups of support group one and support group two. The support group one and the support group two are arranged alternately along the horizontal plane. Each group of support group one or support group two contains two support columns. The support columns of support group one and the support columns of support group two are staggered in height on the support surface. The distance between adjacent support group one and support group two is equal to the sum of the thickness of the casting bulge and the height of the convex column protruding from the bulge;

[0007] When stacking, the following method is adopted: The workpieces are placed on the tooling in sequence from left to right or from right to left. When placing, among adjacent workpieces, if one is placed upright, the other is placed upside down. The bottom surface of the upright workpiece is placed on the shorter support column. For the upside-down workpiece, the protrusion of the workpiece is located between the support columns of the same group, and the steps on both sides of the protrusion are supported by the taller support columns. The convex column on one of the adjacent workpieces is in contact with the side surface of the opposite protrusion of the adjacent other workpiece.

[0008] The principle and advantages of this solution are as follows:

[0009] When adopting this solution, with the help of the grouped support columns on the tooling, the workpieces can be placed in an alternating manner of upright and upside-down, so that the adjacent workpieces are limited in the left-right direction, ensuring that all the workpieces placed on the tooling form a complete whole. Under this complete whole, the upper workpieces can be stacked on the lower complete workpieces placed on the tooling. After the upper workpieces are stacked in the same way, a complete whole is also formed between the same layers. Before transportation, the upper and lower workpieces can be tied together with ropes, greatly improving the overall stability of the workpieces stacked on the tooling, ensuring that the stacking of the special-shaped winged plate castings becomes feasible, and ensuring safety during both the stacking process and after stacking, greatly reducing the transportation cost.

[0010] Preferably, as an improvement, when adjacent workpieces are placed, they are placed with a front-back offset. The offset size is equal to or slightly larger than the maximum distance between the outer circumference of the convex column on the same workpiece and the root of the corresponding flange. The workpieces placed in the same way are located on the same straight line.

[0011] Beneficial effects: By adopting this stacking method and setting the offset size during placement, adjacent three workpieces achieve offset cancellation in the workpiece length direction by relying on the positional relationship between the convex column and the flange. And because the workpieces placed in the same way are located on the same straight line, among adjacent workpieces, if the convex column on one workpiece is located in front of the flange of the adjacent next workpiece, then the convex column of the next workpiece is located behind the flange of the next-next workpiece, ensuring that more than three workpieces form a complete whole with self-limitation in the front-back direction by their own structures after being arranged in the same layer, ensuring the stability after stacking; and because the protrusion of the upside-down workpiece is located between the support columns of the same group, during transportation, the support columns limit the front-back displacement of the protrusion, making the front-back position of the lower workpieces very stable during transportation, ensuring the stability of the transportation process.

[0012] Preferably, as an improvement, the storage tooling further includes two groups of limiting groups. Support group one and support group two are located between the two groups of limiting groups. Each limiting group includes two limiting columns, and the limiting columns are higher than the support columns. After the workpieces on the same layer are placed, a clamping block is inserted between the workpiece at the edge and the limiting column.

[0013] Beneficial effects: Through the arrangement of the limit posts and the insertion of the clamping blocks, the workpieces in the lower layer can form a complete whole with the tooling. All the workpieces in the lower layer are limited in the front, back, left, and right directions with the tooling, improving the stability of the lower-layer workpieces and laying a better foundation for the stable placement of the upper-layer workpieces.

[0014] Preferably, as an improvement, after the lower-layer workpieces are placed, the upper-layer workpieces are placed on the top surface of the lower-layer workpieces in the order from left to right or from right to left; when placing, among adjacent workpieces, if one is placed upright, the other is placed upside down; among adjacent workpieces, the convex post on one workpiece is in contact with the opposite convex side of the adjacent workpiece, and the upper-layer workpieces are kept consistent with the lower-layer workpieces in the front and back misalignment.

[0015] Beneficial effects: When adopting this solution, by utilizing the structural characteristics of the workpieces themselves and the arrangement of the support columns of the tooling, after the upper-layer workpieces are placed in the same way as the lower-layer workpieces, the upper-layer workpieces form a complete whole in the left-right direction. Also, by using the misaligned cooperation of the convex posts and the flanges, self-limitation of adjacent workpieces in the front-back direction is achieved, ensuring that all the upper-layer workpieces form a complete whole, and improving the feasibility, stability, and safety of stacking the upper-layer workpieces.

[0016] Preferably, as an improvement, after the upper-layer workpieces are placed, ropes are used to tie the upper-layer workpieces and the lower-layer workpieces together. In this way, the overall stability of the lower-layer workpieces as a whole and the overall of the upper-layer workpieces are utilized to improve the overall stability of the stacked workpieces, which is beneficial to improving the stability during transportation.

[0017] Preferably, as an improvement, the limit posts are fixed on the support columns located at the edges, and adjacent support columns are connected by connecting pieces.

[0018] Beneficial effects: When adopting this solution, through the arrangement of the connecting pieces, adjacent support columns are connected, improving the connection stability between the support columns and the overall strength of the tooling.

[0019] Preferably, as an improvement, each limit post is in a frame shape. Through the arrangement of the frame-shaped limit posts, on the one hand, it is convenient to put the clamping blocks between the workpieces at the edge and the limit posts, and on the other hand, the frame-shaped structure of the limit posts can be used to facilitate the penetration of the lifting ropes. After the workpieces are stacked on the tooling, a crane or a hoist can be used for unified lifting and transfer, improving the convenience of transfer.

[0020] Preferably, as an improvement, the support columns on the same side are fixed on the same connecting piece at the same time.

[0021] Beneficial effects: This solution makes all the support columns on the same side form a whole, further improving the overall strength of the tooling.

[0022] Preferably, as an improvement, the support column includes a supporting member and a column. The column is fixed below the supporting member. The column includes an upper hollow column and a lower hollow column. A connecting member is fixed between the upper hollow column and the lower hollow column.

[0023] Advantageous effects: When adopting this solution, in the way of the hollow column, while ensuring the strength of the column, the weight of the column is reduced; and the connecting member is fixed between the upper hollow column and the lower hollow column. The local force of the support column can be transmitted to both sides through the connecting member, thereby reducing the stress concentration of a single column, enabling the overall fixture formed to support the workpiece, which is beneficial to extending the service life of a single support column and improving the load-bearing performance of the fixture.

[0024] Preferably, as an improvement, the column of the support column further includes a first reinforcing member and a second reinforcing member. The first reinforcing member and the second reinforcing member clamp the upper hollow column and the lower hollow column, and both the first reinforcing member and the second reinforcing member are fixedly connected to the supporting member.

[0025] Advantageous effects: When adopting this solution, through the arrangement of the first reinforcing member and the second reinforcing member, the overall strength of the support column is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is a further detailed description through specific embodiments:

[0040] The reference numerals in the accompanying drawings of the specification include: the first support group 20, the second support group 30, the support column 2, the backing plate 21, the supporting member 22, the column 23, the upper hollow column 231, the lower hollow column 232, the first reinforcing member 233, the second reinforcing member 234, the workpiece 10, the protrusion 11, the wing plate 12, the flange 13, the convex column 14, the step 15, the connecting piece 3, the limiting group 40, and the limiting column 4.

[0041] Embodiment

[0042] Combined with Figures 3 to 13 , a stacking method for a casting with a wing plate requires the use of a storage tooling, including at least two groups of the first support group 20 and the second support group 30. The first support group 20 and the second support group 3 are arranged alternately along the horizontal plane. Each group of the first support group 20 or the second support group 30 contains two support columns 2. The support columns 2 of the first support group 20 and the support columns 2 of the second support group 30 are staggered in height on the support surface. In this embodiment, the support surface height of the first support group 20 is higher than the support surface height of the second support group 30. The height difference between the first support group 20 and the second support group 30 enables the workpiece 10 placed upside down on the first support group 20 and the workpiece 10 placed upright on the second support group 30 to satisfy that the convex column 14 of one workpiece 10 is within the height range of the flange 13 of the adjacent other workpiece 10, so as to facilitate the formation of front and back self-limitation for the placed workpiece 10 by using the flange 13 and the convex column 14 after stacking.

[0043] The distance between the adjacent first support group 20 and the second support group 30 is equal to the sum of the thickness of the casting protrusion 11 and the height of the convex column 14 protruding from the protrusion 11. The support column 2 is used to support the bottom surface of the workpiece 10 or the step 15 surface of the workpiece 10. The distance between the two support columns 2 in the same group is equal to the distance between the two steps 15 on the same workpiece 10.

[0044] The adjacent support columns 2 are welded through the connecting members 3. The support columns 2 on the same side are simultaneously welded to the same connecting member 3. The number of the connecting members 3 is four, and the four connecting members 3 are welded to form a frame structure.

[0045] Each support column 2 is in a T shape. The connecting member 3 is welded to the middle or lower part of the T-shaped support column 2. A backing plate 21 is welded to the bottom of the support column 2. The backing plates 21 of all the support columns 2 are located on the same plane. Specifically, each support column 2 includes a supporting member 22 and a column 23. The column 23 is welded below the supporting member 22. The column 23 includes an upper hollow column 231, a lower hollow column 232, a first reinforcing member 233 and a second reinforcing member 234. The upper hollow column 231 and the lower hollow column 232 are arranged vertically in the height direction. The upper hollow column 231 and the lower hollow column 232 are located directly below the supporting member 22. The connecting member 3 is welded between the upper hollow column 231 and the lower hollow column 232.

[0046] The first reinforcing member 233 and the second reinforcing member 234 are symmetrically arranged with respect to the upper hollow column 231. The first reinforcing member 233 and the second reinforcing member 234 clamp the upper hollow column 231 and the lower hollow column 232. The first reinforcing member 233 and the second reinforcing member 234 are both welded to the side surface of the supporting member 22.

[0047] It further includes two groups of limiting groups 40. All the first support groups 20 and the second support groups 30 are located between the two groups of limiting groups 40. Each limiting group 40 includes two limiting columns 4. The limiting columns 4 are higher than the support columns 2. The limiting columns 4 are welded to the supporting members 22 of the edge support columns 2.

[0048] The stacking method of the wing plate  12 castings using the above tooling is as follows:

[0049] S1. The workpieces 10 are placed on the tooling in sequence from left to right or from right to left. When placing, among adjacent workpieces 10, one is placed upright and the other is placed upside down. The bottom surface of the upright workpiece 10 is placed on the shorter support post 2. For the upside-down workpiece 10, the protrusion 11 of the workpiece 10 is located between the support posts 2 of the same group, and the steps 15 on both sides of the protrusion 11 are supported by the taller support posts 2. The convex post 14 on one of the adjacent workpieces 10 is in contact with the side surface of the protrusion 11 opposite to the other adjacent workpiece 10. When adjacent workpieces 10 are placed, they are placed with a front-back offset. The offset dimension is equal to or slightly larger than the maximum distance between the outer circumference of the convex post 14 on the same workpiece 10 and the root of the corresponding flange 13. The workpieces 10 placed in the same way are located on the same straight line. In this embodiment, the offset dimension is equal to the maximum distance between the outer circumference of the convex post 14 on the same workpiece 10 and the root of the connected flange 13, so that the workpieces 10 placed with a front-back offset from left to right can utilize the convex post 14 and the flange 13 to form a situation where both rear limit and front limit coexist. Furthermore, under the simultaneous limit of the front limit and the rear limit, all the workpieces 10 placed on the same layer form a complete whole. For the upside-down workpiece 10, its protrusion 11 is located between the support posts 2 of the same group, which is convenient for using the space between the support posts 2 of the same group to form the front-back limitation of the upside-down workpiece 10. On the basis that all the workpieces 10 on the same layer form an integral body, plus the limitation of the upside-down workpiece 10 by the tooling, the lower-layer workpieces 10 can be placed on the tooling very stably as a whole.

[0050] During the placement process, the convex posts 14 on the workpieces 10 at both left and right ends are made to face the inner workpiece 10 to ensure the smallest volume after the workpieces 10 on the same layer are arranged.

[0051] S2. After the workpieces 10 on the same layer are placed, blocks are inserted between the workpieces 10 at the edge and the limit posts 4 to further improve the placement stability of the lower-layer workpieces 10 and enhance the placement safety of the workpieces 10.

[0052] After the lower-layer workpieces 10 are placed, the upper-layer workpieces 10 are placed on the top surface of the lower-layer workpieces 10 in sequence from left to right or from right to left; when placing, the placement method is the same as that of the lower-layer workpieces 10, that is, among adjacent workpieces 10, one is placed upright and the other is placed upside down; also, the convex post 14 on one of the adjacent workpieces 10 is kept in contact with the side surface of the protrusion 11 opposite to the other adjacent workpiece 10. The upper-layer workpieces 10 are kept consistent with the lower-layer workpieces 10 in terms of front-back offset to simplify the placement difficulty of the upper and lower-layer workpieces 10.

[0053] After the upper-layer workpieces 10 are placed, the upper-layer workpieces 10 and the lower-layer workpieces 10 are tied together with ropes.

[0054] Of course, in order to further improve the connection stability between the workpiece 10 and the tooling, after the upper and lower layer workpieces 10 are bundled into a whole, ropes can be used to connect the lower layer workpiece 10 with the clamping block inserted therein to the limit post 4.

[0055] The tooling of this embodiment enables the stacking of the winged plate 12 castings, which can greatly increase the number of workpieces 10 transported each time and reduce the transportation cost (before the implementation of this embodiment, transporting 3 pieces each time was the safest, and at most 6 pieces could be transported. After the improvement, the number of transported pieces can reach 10, and the placement is very stable and safe); moreover, the stacking process of the workpieces 10 becomes simple and convenient, improving the stacking efficiency, and during the stacking process of the workpieces 10, the adjacent workpieces 10 are mutually limited by using the stacking method, improving the safety during the stacking process; after the stacking is completed, by inserting the clamping block and tying the ropes, the overall sense between the workpiece 10 and the tooling is further improved, the stability of the workpiece 10 placed on the tooling is improved, and the stability during the transportation process is ensured.

[0056] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
