Abstract
A bending edge hasp connecting structure of a sheet metal type box-shaped piece adopts a bending edge hasp connecting structure between adjacent side edges of the box-shaped piece, and comprises an inner connecting edge arranged on the end part of one of two adjacent vertical side edges and an outer connecting edge arranged on the end part of the other vertical side edge; the interior border is punched with the hanging buckle via hole, so that not only the connection between the adjacent sides is stable and firm, but also the automatic production of the sheet metal box-shaped piece is facilitated, therefore, the utility model has the advantages of reasonable and simple structure.
Description
Technical Field
The utility model relates to a sheet metal connection mode especially indicates the connection structure of box-shaped piece between adjacent limit of bending that becomes at the panel beating punching press.
Background
Currently, the sheet-metal box-shaped element, the links between the adjacent bent edges thereof are generally produced by welding processes, which leads to the processes from the material to the finished product that could be completed in one production line, but must be produced in sections, thus resulting in an increase in the cost of personnel and equipment, and also not being beneficial to automation or edge-to-edge mould production. In order to solve these problems, the applicant has developed a special link of adjacent folded edge buckles.
Disclosure of Invention
An object of the utility model is to provide a limit hasp connection structure of bending of rational in infrastructure and simple, stable and firm sheet metal type box-shaped piece of connection, it helps sheet metal type box-shaped piece's automated production.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a bending edge hasp connecting structure of a sheet metal type box-shaped piece is disclosed, wherein a body of the box-shaped piece comprises a bottom edge and at least three vertical side edges, and the bending edge hasp connecting structure comprises an inner connecting edge arranged on the end part of one of two adjacent vertical side edges and an outer connecting edge arranged on the end part of the other vertical side edge; a hanging buckle through hole is punched on the inner connecting edge; a tongue-shaped hanging buckle folded towards the direction of the folded edge is punched on the outer connecting edge; when the inner and outer edges are attached, the tongue-shaped hanging buckle can be inserted into the hanging buckle via hole.
In the improvement scheme of the bending edge hasp connection structure of the sheet metal type box-shaped piece, the external connecting edge is compared with the vertical side where the external connecting edge is located, and the distance between the external connecting edge and the vertical side where the external connecting edge protrudes outwards is equal to the thickness of a sheet metal.
Compared with the prior art, the beneficial effects of the utility model are that: because the adjacent sides of the box-shaped piece adopt the bent edge hasp connection structure, the bent edge hasp connection structure comprises an inner connection edge arranged on the end part of one of the two adjacent vertical side edges and an outer connection edge arranged on the end part of the other vertical side edge; the interior border is punched with the hanging buckle via hole, so that not only the connection between the adjacent sides is stable and firm, but also the automatic production of the sheet metal box-shaped piece is facilitated, therefore, the utility model has the advantages of reasonable and simple structure.
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
[ description of the drawings ]
Fig. 1 is a first perspective view of the present invention;
FIG. 2 is an enlarged view of section I of FIG. 1;
FIG. 3 is a schematic perspective view of the body of the box-shaped member of the present invention prior to crimping and bending the snap-fit connection;
fig. 4 is a process flow chart of the bending snap connection process of the present invention.
[ detailed description ] embodiments
A bending edge snap-fit connection structure of a sheet metal type box-shaped piece is shown in figures 1 to 3, wherein a body 1 of the box-shaped piece comprises a bottom edge 11 and at least three vertical side edges 12, and a bending edge snap-fit connection structure 2 comprises an inner connecting edge 21 arranged on the end part of one of the two adjacent vertical side edges 12 and an outer connecting edge 22 arranged on the end part of the other vertical side edge; a hanging buckle through hole 211 is punched on the inner connecting edge 21; the inner connecting edge 21 is folded inwards and then is perpendicular to the bottom edge 11 and the vertical side edge 12 where the bottom edge is located; a tongue-shaped hanging buckle 221 which is folded towards the folding direction is punched on the external connecting edge 22 and is basically vertical to the external connecting edge; when the inner and outer edges 21, 22 are engaged, the tongue-shaped hooks 221 can be inserted into the hook through holes 211.
The main body 1 of the box-shaped member is formed by stamping a sheet metal part, in the embodiment, as shown in fig. 3, three vertical side edges 12 on the bottom edge 11 are provided (for convenience of description, the three side edges are respectively defined as a left side edge, a front side edge and a right side edge), and considering the actual use requirement of the box-shaped member of the embodiment, only two vertical side edges on the front side and the right side are connected through a bent edge snap connection structure 2; and the left vertical side and the front vertical side are not connected through a bent side snap connection structure.
When the body 1 is to be formed into a box, the following steps are included, as shown in fig. 4:
1) bending the left and front sides upwards, and bending the left and front sides inwards to form the inner connecting edge 21 on the front side;
2) bending the right side upwards for forming, wherein the hanging buckle 221 on the external connecting side 22 is obliquely inserted into the hanging buckle through hole 211 of the internal connecting side 21, when the bending of the right side is finished, the external connecting side 22 is attached to the outside of the internal connecting side 21, and the hanging buckle 221 penetrating into the hanging buckle through hole 211 is in a horizontal state;
3) finally, the hanging buckle 221 is bent downward to buckle on the inner connecting edge 21, so that the bending and buckling connection of the front side and the right side is completed.
From the above, the structure that the limit hasp connection that adopts to bend made adjacent both sides limit to connect not only makes the connection between the adjacent side stable and firm, helps the automated production of panel beating formula box-shaped piece moreover (because every step all can be accomplished all processes with the mould, and just can accomplish on a production line), consequently the utility model discloses a rational in infrastructure and simple.
In this embodiment, in order to make the connection of the front and right sides at the corner more reasonable and the gap smaller, the external edge 22 is protruded outward and the protruding distance is equivalent to the thickness of the metal plate compared with the vertical side 12, as shown in fig. 1 to 3, so that when the body is stamped, the external edge 22 is punched outward to protrude outward to the right side.
Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the present disclosure, but rather to limit the scope thereof by the appended claims.
