Description

Technical Field

[0001] This utility model relates to the field of paper folding tube technology, specifically to a long-end paper folding tube processing device. Background Technology

[0002] Introducing a folding pattern into the impact resistance design of thin-walled tubes can effectively reduce the initial peak force, guide the structure to deform according to the preset folds, improve the energy absorption effect, and simplify the processing technology. When the folding pattern is introduced into square tubes in the traditional way, the folds are all over the entire surface of the structure. Although this design may bring a certain improvement in impact resistance, the processing is extremely troublesome.

[0003] The novel end-folding tube cleverly introduces an origami pattern to the ends or specific areas of traditional tubes. This design concept is based on a deep understanding of the deformation characteristics of thin-walled tubes during collisions, recognizing that the ends or specific areas of the tube are often the starting and critical regions for deformation. By introducing origami structures into these critical locations, deformation can be guided in a predetermined manner, while avoiding complex origami operations on the entire surface of the tube. However, it also presents the problem of complicated processing, as the various structural parts of the origami pattern need to be connected by spot welding, which not only increases the complexity of the process but may also affect the overall structural performance due to welding quality.

[0022] Example 1

[0023] refer to Figures 1-4 This embodiment provides a long-end folding tube processing device, the purpose of which is to solve the problem of the troublesome processing of introducing folding patterns at the end or local area of ​​traditional tubes in existing thin-walled tubes. The specific structure of this embodiment will be described in detail below.

[0024] A long-end folding tube processing device includes a processing outer frame 1.

[0025] The outer frame 1 is equipped with a processing mold assembly that acts on the square tube 3 via a support platform 2.

[0026] Specifically, the processing mold assembly includes an inner processing mold 4 for fitting the square tube 3, an outer processing mold 5 that cooperates with the inner processing mold 4 and acts on the square tube 3, and a jack 6 that acts on the outer processing mold 5 and is located on the top of the inner side of the outer processing frame 1.

[0027] In this embodiment, the square tube 3 is fitted onto the inner processing mold 4, and the inner processing mold 4 with the square tube 3 fitted onto it is placed inside the outer processing frame 1. The outer processing mold 5 is placed above the square tube 3. The jack 6 inside the outer processing frame 1 applies pressure to the outer processing mold 5 above the inner processing mold 4, causing the outer processing mold 5 to squeeze the inner processing mold 4, thereby causing the square tube 3 to crease and deform, forming a folded paper tube.

[0028] This utility model has a simple structure and is easy to process. It does not require spot welding and splicing. The square tube 3 can be deformed by stamping to form a paper-folded tube, which makes it easier to achieve large-scale production.

[0029] Specifically, the inner mold 4 has multiple processing grooves 41 in the middle, and the outer mold 5 has multiple processing protrusions 51 at the bottom that fit the processing grooves 41.

[0030] In this embodiment, a processing groove 41 is provided in the middle of the inner mold 4. The number, shape and specifications of the processing groove 41 can be set according to actual needs. A processing protrusion 51 is provided at the bottom of the outer mold 5. The processing protrusion 51 fits into the processing groove 41. Through the cooperation of the processing protrusion 51 and the processing groove 41, the square tube 3 is deformed by creases to form a folded paper tube.

[0031] Specifically, the inner mold 4 is provided with first limiting grooves 42 at both ends, and first limiting baffles 43 are inserted in the first limiting grooves 42; the outer mold 5 is positioned between the two first limiting baffles 43.

[0032] In this embodiment, both the inner mold 4 and the outer mold 5 are rectangular. A first limiting groove 42 is provided at both ends of the end face surface of the inner mold 4 along one long direction. If necessary, a first limiting groove 42 can also be provided on the end face surface of the inner mold 4 along each long direction. A first limiting baffle 43 is inserted into the first limiting groove 42, and the two first limiting baffles 43 provide limiting guidance for the outer mold 5.

[0033] Specifically, a pressure transmission block 7 is provided between the jack 6 and the outer mold 5.

[0034] In this embodiment, the jack 6 is an existing hydraulic jack, and the upper part of the pressure transmission block 7 is tapered from low to high. The bottom surface area of ​​the pressure transmission block 7 is larger than the upper surface area of ​​the outer mold 5, and the top surface area of ​​the pressure transmission block 7 is larger than the end face area of ​​the output shaft on the jack 6. The pressure transmitted by the jack 6 can be evenly applied to the outer mold 5 through the pressure transmission block 7.

[0035] Specifically, the lower surface of the pressure transmission block 7 is provided with second limiting grooves 71 at both ends, and the upper surface of the outer mold 5 is provided with limiting posts 52 that fit into the second limiting grooves 71 at both ends, with the limiting posts 52 embedded in the second limiting grooves 71.

[0036] In this embodiment, the limiting post 52 on the upper surface of the outer mold 5 is inserted into the second limiting groove 71 on the lower surface of the pressure transmission block 7, which makes it easier to determine the position of the pressure transmission block 7 and prevents the pressure transmission block 7 from sliding.

[0037] Specifically, the support platform 2 is provided with a second limiting baffle 21 at each end.

[0038] In this embodiment, the support platform 2 is a rectangular body that fits the outer frame 1. Placement slots are provided at both ends of the upper surface of the support platform 2. Second limiting baffles 21 are inserted into the placement slots. The two second limiting baffles 21 provide limiting guidance for the inner mold 4. The second limiting baffles 21 can be placed on one side or both sides as needed.

[0039] Specifically, threaded holes 11 are provided on both sides of the outer frame 1, and locking bolts 12 are inserted into the threaded holes 11 to act on the square tube 3 fitted on the inner mold 4.

[0040] In this embodiment, the locking bolt 12 is inserted into the threaded hole 11 to lock the inner processing mold 4 on which the square tube 3 is sleeved, thereby preventing the inner processing mold 4 from moving.

[0041] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent.
