Description

Technical Field

[0001] This invention relates to container reinforcement components, and more specifically to an integrated manufacturing apparatus and method for end sealing plates of container reinforcement components. Background Technology

[0002] Container reinforcement components need to be installed in a sealed manner with the container walls. The forming process of container reinforcement components is described in [link to documentation]. Figure 1 , Figure 2 Generally, it is formed by bending an irregular channel steel 01 with open ends, and welding an end sealing plate to the open ends. The end sealing plate is welded together with an irregular sealing plate 02 and a connecting plate 03. The channel steel 01 is then welded to the end sealing plate to form a closed state on all four sides. This technology has the following defects: (1) The sealing plate 02 and the connecting plate 03 are first spliced ​​into a component, and then welded to the channel steel 01. The process is long, which increases the cost and raises the risk of quality.

[0003] (2) In order to ensure the welding quality, all splicing welds need to be beveled. The channel steel 01, the sealing plate 02 and the connecting plate 03 all need to be beveled. However, the parts are small and the bevels are not easy to be made, which poses a safety risk and is costly.

[0004] (3) The size of the sealing plate 02 is small, and the rounded corners at the ends have not been separated from the bending area, resulting in incomplete bending at the ends and large gaps, which affects the welding quality.

[0005] (4) The sealing plate 02 and the connecting plate 03 are spliced ​​together to form a component. The assembly angle is 165 degrees. The angle is not easy to control and the accuracy of the parts cannot be guaranteed.

[0006] (5) In order to reduce the workload of beveling and welding, Scheme 2 is proposed, which combines the sealing plate 02 and the connecting plate 03 into a sheet metal part and integrally forms it. However, it has multiple forming directions and cannot be processed by existing methods such as bending. Summary of the Invention

[0028] This invention provides an integrated manufacturing apparatus for end caps of container reinforcement components, such as... Figure 3As shown, the integrated manufacturing device includes an upper mold body 1 and a lower mold body 2 distributed vertically, an upper insert 11 disposed below the upper mold body 1, a lower insert 21 disposed above the lower mold body 2, four upper safety limit posts 12 disposed below the upper mold body 1 and located around the upper insert 11, and four lower safety limit posts 22 disposed above the lower mold body 2 and located around the lower insert 21; the four upper safety limit posts 12 and the four lower safety limit posts 22 are arranged in a vertically corresponding manner; it also includes two L-shaped lateral force balancing blocks 14 disposed opposite to each other, a liner plate 4 disposed at the bottom of the lower mold body 2, and an ejection mechanism 25.

[0029] A guide post 13 is provided on the bottom of the upper mold body 1 and on both sides of the upper insert 11; the guide post 13 is fixedly connected to the upper mold body 1; a guide sleeve 23 is provided on the top of the lower mold body 2 and on both sides of the lower insert 21; the guide sleeve 23 is fixedly connected to the lower mold body 2; the two guide posts 13 are respectively set to correspond to the two guide sleeves 23.

[0030] like Figure 4 , Figure 5 As shown, the upper insert 11 has a raised area on its lower side; the raised area matches the shape of the end cap 3 to be manufactured; the lower insert 21 has a recessed area 211 on its upper side; the recessed area 211 matches the shape of the end cap 3 to be manufactured and corresponds to the raised area; the lower insert 21 has 4 positioning pins 24; the 4 positioning pins are distributed around the recessed area; the upper insert 11 has 4 positioning holes, the 4 positioning holes correspond one-to-one with the 4 positioning pins 24, and are used to position the raw materials to be cut.

[0031] The lateral force balancing block 14 includes a vertical block and a horizontal block vertically connected to the upper end of the vertical block; a balancing notch 212 is provided on each side of the lower insert 21; the two lateral force balancing blocks 14 are respectively installed on both sides of the lower insert 21, and the two vertical blocks are respectively embedded in the two balancing notches 212, and the two horizontal blocks overlap on the upper part of the lower insert 21.

[0032] The liner 4 is parallel to the lower mold body 2, and multiple pads 42 are vertically arranged between the liner 4 and the lower mold body 2, forming an installation space between the liner 4 and the lower mold body 2. The lower insert 21 is provided with a first ejection through hole that runs through it from top to bottom and corresponds to the recessed area 211; the lower mold body 2 is provided with a second ejection through hole that runs through it from top to bottom and corresponds to the first ejection through hole; the lower end of the ejection mechanism 25 is fixedly installed on the liner 4, and the ejection end passes through the second ejection through hole and the first ejection through hole from bottom to top, and an ejection spring is provided on the end face of its ejection end.

[0034] The manufacturing process using the aforementioned integrated manufacturing device for container reinforcement end caps includes the following steps: Step 1: Draw the unfolded shape of the end cover plate 3 to be manufactured based on the metal extension parameters of the raw material (sheet metal) of the end cover plate 3 to be manufactured; Step 2: Based on the drawn unfolded shape, use laser cutting to cut raw materials; laser cutting ensures accuracy, one-time forming, and secondary reshaping if the forming is not ideal, to ensure the overall size after forming, taking springback into account; ensure that the gap between the end sealing plate and the reinforcing member weld meets the welding requirements, with a pass rate of 100%.

Moreover, this invention is applicable to the manufacturing requirements of groove-shaped parts with various sealing cavity requirements, and has extremely strong versatility.

[0037] When product design does not allow for welds at the corners where the top surface of the channel steel transitions to the box wall, this invention can be used. The integrated end-cap molding solution allows for flexible selection of the weld location based on design requirements, avoiding the limitation of welding at corners. This avoids the need for an integrated molding solution where the reinforcing component and end-cap form a sealed cavity to meet design requirements. The integrated molding solution for the reinforcing component, due to the varying lengths of the reinforcing components, necessitates the customization of multiple specialized molds, resulting in poor mold versatility. For reinforcing components exceeding 5 meters in length, conventional equipment struggles to achieve complete molding, and excessive length can lead to quality defects such as poor straightness and distortion. This invention allows for the practical implementation of this splicing solution, avoiding these problems.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
