Embodiment Construction

[0041] The above and other features and advantages of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Such as Figure 9 , Figure 10 As shown, when the present invention is making the seat body 30 of the metal tool box, it first takes an appropriate metal plate for extraction processing, and uses a mold to integrally stretch and form the base body 30 at the center of the metal tool box. , the base 30 is formed with a bottom plate 301 and a side plate 302 with arc angles, and at the same time, several grooves 303 are formed outside the bottom plate 301; please refer to Figure 9 , 11 As shown, the base body 30 rough blank is then punched to form several perforations 304 on the groove 303 of the base body 30 rough blank. refer to Figure 9 , 12 As shown, the edge removal process is carried out, which is to remove the remaining material around the rough base of the seat body 30 by punching and shearing; refer to ...

Abstract

The invention discloses a metal tool box structure and a forming method thereof. The forming method comprises the following steps: integrally forming a rough seat body blank and a rough cover body blank with corresponding shapes and circular arc angles by proper metal plates in a drawing mode respectively, removing the residual materials around the rough seat body blank and the rough cover body blank in a mode of stamping and shearing respectively, and trimming and flattening circular arc sections and linear sections at opening end edges of the rough seat body blank and the rough cover body blank respectively, wherein in a seat body, the circular arc section and the linear section at the top of a lateral plate are inwards bent in a mode of stamping and bending respectively to form inwards bent flanges at the top of the lateral plate, the seat body and a cover body are assembled and connected by a hinge device, and the inner edge of the cover body is sleeved with the flange of the seat body during covering. Therefore, the strength and the durability of the tool box are increased; not only the seat body and the cover body are accurately aligned, but also the appearance of the tool box is flattened; and the service life and the appearance esthetics are greatly promoted.

Description

technical field [0001] The invention relates to a tool box, in particular to a metal tool box structure and a forming method thereof. Background technique [0002] At present, there are manufacturers in the market that use metal sheets to make tool boxes with a base and a cover for storing finishing tools; please refer to figure 1 As shown, it is a schematic diagram of the production procedure of the conventional tool box base 10. It is to form a rough blank of the base 10 by stamping and shearing a suitable metal sheet. The center of the blank is the bottom plate 101, and the sides of the bottom plate 101 are respectively formed into side plates 102, and then each side plate 102 is formed into the shape of the seat body 10 by stamping and bending, and then between the side plates 102 with The way of welding is respectively fixed to an L-shaped piece 103, which completes the production of the seat body 10; please refer to figure 2 As shown, it is a schematic diagram of th...
