Background

The manufacturing of lightweight plate with honeycomb structure is a common technical means in the prior art, for example, patent document with application publication number CN 106121482 a discloses an aluminum honeycomb panel partition door for rail transit. The honeycomb structure is generally arranged in the interlayer of the plate, and the side wall of the honeycomb structure is perpendicular to the side wall of the plate, so that the side wall of the plate is strongly supported. However, in the case of a plate having a bent structure, if a conventional honeycomb structure is directly filled in the interlayer of the bent structure, it is difficult to ensure that the side wall of the honeycomb structure is perpendicular to the side wall of the bent structure of the plate, and thus the strength of the bent structure is weak, and the plate is easily deformed at this position.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the honeycomb structure is filled in the bending structure of the plate, and the side wall of the honeycomb structure can be perpendicular to the side wall of the bending structure of the plate.

Detailed Description

A honeycomb structure is filled in a bent structure 10 of a plate, and the bent structure of the plate comprises an outer plate 11 with a larger inner diameter and an inner plate 12 with a smaller inner diameter, which are combined with figures 3 and 4. The honeycomb structure is filled between the inner layer plate and the outer layer plate. The inner layer plate and the honeycomb structure can be connected through glue, and the outer layer plate and the honeycomb structure can be connected through glue.

With reference to fig. 1 and 2, the honeycomb structure includes honeycomb side walls 20 and a side wall connection structure 30, the side wall connection structure includes vertical walls 31 and a plurality of wave walls 32 arranged between the honeycomb side walls, the vertical walls are provided with creases 33, and any wave wall is in a wave shape. The vertical wall is located in the middle between the honeycomb side walls of the upper-layer structure and the lower-layer structure, the plurality of wave walls 32 can be distributed on one side of the vertical wall 31 and can also be distributed on two sides of the vertical wall, and preferably, the plurality of wave walls 32 are distributed on two sides of the vertical wall 31, so that the strength between the honeycomb side walls of the upper-layer structure and the lower-layer structure is enhanced, and the stability of the honeycomb side walls in the using process is improved.

The honeycomb side wall 20 on one side of the vertical wall 31 is pressed, the honeycomb side wall on the upper layer and the honeycomb side wall on the lower layer rotate oppositely by taking the crease 33 of the vertical wall as a rotation center line, and synchronously, the honeycomb side wall on the other side of the vertical wall is mutually far away. Meanwhile, the wavy wall 32 between the two honeycomb side walls close to each other tends to fold, and the wavy wall between the two honeycomb side walls far away from each other tends to stretch, as shown in fig. 2.

One end of the honeycomb side wall 20 which is far away from each other is pressed against the side wall of the outer layer plate 11, and one end of the honeycomb side wall which is close to each other is pressed against the side wall of the inner layer plate 12. The honeycomb side walls can be perpendicular, or nearly perpendicular, to both the outer sheet side walls and the inner sheet side walls.

With reference to fig. 1 and 2, the wave walls 32 on either side of the vertical wall 31 are arranged in rows, or at least one row of wave walls 32 is arranged on either side of the vertical wall 31. And a gap is formed between two adjacent rows of wave walls. Any row of wave walls is parallel to the vertical wall 31. The purpose that a plurality of rows of wave walls and gaps exist between two adjacent rows of wave walls is set: if the width of the wavy wall is too large and the width direction is perpendicular to the vertical wall, the connection between the wavy wall and the honeycomb side wall 20 will generate internal stress when the honeycomb side wall rotates around the crease 33, and the stress can cause cracks to be generated at the connection; the wave walls are smaller in width, and a plurality of rows of wave walls are arranged, so that the stress at the joint is correspondingly reduced, and the connection strength between the honeycomb side walls 20 of the upper-lower layer structure is not influenced.

The bent part of the wavy wall 32 on one side of the vertical wall 31 is connected with a connecting strip 34, and one end of the connecting strip protrudes out of the honeycomb structure. The connecting strips are parallel to the vertical wall, and after the honeycomb side wall 20 on one side of the vertical wall 31 is pressed, the distance between the bending part of the wavy wall and one edge of the honeycomb structure is reduced, wherein the wavy wall tends to be in a folded state. Since the connecting strips protrude beyond the edge, the operator punches a hole in the connecting strip and inserts the pin 40 into the hole, as shown in fig. 2, which presses against the edge, preventing the wave wall, which tends to be folded, from returning, thus ensuring that the honeycomb side wall 20 is in the pressed state. During manufacturing, the connecting strip can be integrally formed with the wave wall, for example, a plastic part can be formed by injection molding, and a metal part can be formed by casting. The connection between the vertical wall and the honeycomb side wall and the connection between the wave wall and the honeycomb side wall can be realized by glue, and the vertical wall, the wave wall and the honeycomb side wall which are made of metal materials can be welded, riveted or screwed. Preferably, a connecting strip is attached to the folds of the row of corrugated walls to avoid deformation of the honeycomb structure after being pressed into a deformed shape, e.g., the deformation of the honeycomb side walls 20 at the connecting strip 34 is expected, while the honeycomb side walls away from the connecting strip are warped.

As shown in fig. 2, any one of the wavy walls 32 has at least three bending marks 35, and the bending mark 351 located in the middle is inclined to the side bending marks 352 located on both sides of the bending mark in the middle. Any fold is perpendicular or nearly perpendicular to the vertical wall 31. If the three bending marks 35 are parallel, the internal stress at the connection between the wave wall and the honeycomb side wall is large after the honeycomb side wall 20 is pressed, and the crack is easy to occur. The non-parallel arrangement of the three bending marks 35 can effectively reduce the internal stress of the joint. The inclination of the side bending mark 352 is smaller than that of the honeycomb sidewall 20 after being pressed.

The number of the honeycomb side walls 20 is several, the honeycomb side walls are of an upper-layer structure and a lower-layer structure, and the side wall connecting structure 30 is arranged between every two adjacent honeycomb side walls.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
