Abstract
A shell of a metallic cabinet is made by means of folding two ends of a metal plate form fitting portions at the two ends, bending the metal plate and making the fitting portions engage each other to change the metal plate into a semi-finished shell, pressing the fitting portions against each other such that the fitting portions become flat to closely touch each other, and bending upper and lower ends of the semi-finished shell inwards to form inward annular fitting protrusions thereon, shaping the semi-finished shell by means of exerting outward force on inner portions of the semi-finished shell, and punching a front side of the semi-finished shell to form an opening; a cover and a base are respectively secured to the upper and the lower ends with bumps, which are formed near to edges of the cover and the base, engaging the fitting protrusions of the shell.
Description
- 1. Field of the invention
- The present invention relates to a method for manufacturing a shell of a metallic cabinet, more particularly one, according to which a cabinet shell is made by means of folding a metal plate and joining two ends of the metal plate together such that the shell has a simple structure, and manufacturing cost, and time and labor taken in assembling will reduce.
- 2. Brief Description of the Prior Art
- Referring to
FIG. 12 , a conventional shell 4 of a metallic cabinet includes abottom plate 41, front lower and rearlower beams bottom plate 41, twolateral plates 44 secured to lateral edges of thebottom plate 41, arear plate 46 securely connected to rear edges of thebottom plate 41 and thelateral plates 44, atop plate 49 securely connected to upper ends of therear plate 46 and thelateral plates 44, front upper and rearupper beams lateral plates 44 to support thetop plate 49, and several pairs ofrails 45 on inner sides of thelateral plates 44; the above various plates can be joined together by means of screws. And, drawers (not shown) are held in the shell 4 and supported by therails 45 for containing objects or files therein. - The conventional shell has a disadvantage that it consists of many parts. Consequently, the manufacturing cost is relatively high, and it takes much time and labor to assemble the shell.
- It is a main object of the present invention to provide an improvement on a shell of a metallic cabinet to overcome the above disadvantage. The method of the present invention includes: folding two ends of a metal plate form fitting portions at the two ends, bending the metal plate and making the fitting portions engage each other to change the metal plate into a semi-finished shell, pressing the fitting portions against each other such that the fitting portions become flat to closely touch each other, and bending upper and lower ends of the semi-finished shell inwards to form inward annular fitting protrusions thereon, shaping the semi-finished shell by means of exerting outward force on inner portions of the semi-finished shell, and punching a front side of the semi-finished shell to form an opening thereon. After the shell is finished, a cover and a base are respectively secured to the upper and the lower ends with engaging bumps, which are formed near to edges of the cover and the base, engaging the fitting protrusions of the shell.
- The present invention will be better understood by referring to the accompanying drawings, wherein:
-
FIG. 1 is a flow chart of the method for manufacturing a shell of a metallic cabinet according to the present invention, -
FIG. 2 is a view of a metal plate used in the present method, -

FIG. 4 is a view of the metal plate, demonstrating the second step, -
FIG. 5 is a view of the semi-finished sell, showing the third step, -
FIG. 6 is a view of the semi-finished sell, showing the fourth step, -
FIG. 7 is a view of the semi-finished sell, showing the fifth step, -
FIG. 8 is an exploded perspective view of the present shell made according to the method of the present invention, -
FIG. 9 is a view showing one way to use the cabinet shell made according to the method of the present invention, -
FIG. 10 is a view showing another way to use the cabinet shell made according to the method of the present invention, -
FIG. 11 is a view showing yet another way to use the present shell, and -
FIG. 12 is an exploded perspective view of the conventional shell. - Referring to FIGS. 1 to 7, a preferred embodiment of a method for manufacturing a
shell 1 of a metallic cabinet includes the following steps: - (1) folding two ends of a
metal plate 11 so thatfitting portions FIGS. 2 and 3 ; - (2) bending the
metal plate 11 and making thefitting portions metal plate 11 together, as shown inFIG. 4 ; - (3) pressing the
fitting portions portions annular fitting protrusions FIG. 5 ; - (4) shaping the semi-finished shell for the same to have four flat sides by means of exerting outward force on inner portions of the semi-finished shell, as shown in
FIG. 6 ; - (5) forming an
opening 16 on a front side of the semi-finished shell by means of a punch press so that theshell 1 is finished, as shown inFIG. 7 . - Referring to
FIG. 8 , anupper cover 2 and abase 3 are respectively secured on the upper and the lower ends of theshell 1 after theshell 1 is finished; thecover 2 and thebase 3 each has a protrusion projecting from one side and near to the edge thereof, and they have engagingbumps annular fitting protrusions shell 1. - Referring to
FIG. 9 , theshell 1 can be used together withdrawers 161, which are passed to theshell 1 through theopening 16. Referring toFIG. 10 , theshell 1 also can be used together with aninner shell 162, which is held in theshell 1, and in whichdrawers 163 are held. Referring toFIG. 11 , theshell 1 also can be equipped with adoor 164, which is pivoted to those portions of theupper cover 2 and thebase 3 that project out beyond the front side of theshell 1. - From the above description, it can be easily understood that metallic cabinet shells made according to the method of the present invention has much simpler structure than conventional ones as described in Background, and the manufacturing cost, and time and labor needed in assembling will reduce.
