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.

Example Embodiment

[0041] The above and other features and advantages of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0042] Such as Picture 9 , Picture 10 As shown, in the present invention, when the seat body 30 of the metal tool box is made, a suitable metal plate is first taken for drawing processing, and a mold is used at the center of the metal plate to integrally stretch the seat body 30 to form a rough embryo. , The base body 30 rough blank is formed with a bottom plate 301 and a side plate 302 with rounded corners, and a number of grooves 303 are formed outside the bottom plate 301; please refer to Picture 9 , 11 As shown, the rough blank of the seat body 30 is punched to form a number of perforations 304 on the groove 303 of the rough blank of the seat body 30. The perforations 304 are available for installing other components of the tool box; Refer to Picture 9 , 12 As shown, the edge removal process is performed, which is to remove the remaining material around the rough blank of the seat body 30 by means of punching and shearing; please refer to Picture 9 , 13 As shown, the trimming process is then performed, which is that the top of the side plate 302 of the rough base of the seat body 30 is first removed by punching and shearing to remove the burrs of the arc segments, and at the same time, after trimming the seat body 30 to an appropriate height, Then the burrs on one side of the straight section are removed by stamping and shearing, and the notch 305 is formed at the same time, while the burrs on the other three sides are respectively removed in the same way and trimmed to the same height as the arc section at the same time; See Picture 9 , 14 As shown, the hemming process is then carried out, which is to first bend the arc section on the top of the thick embryo side plate 302 of the seat body 30 to the inside by stamping and bending, and then the straight sections on the other three sides are respectively The method of punching and bending is bent inward to form, and the top of the side plate 302 of the thick blank of the seat body 30 forms an inwardly bent flange 306; please refer to Picture 9 , 15 As shown, another punching process can be performed on the rough base of the seat body 30 to form several perforations 307 on the side plate 302 of the rough base of the seat body 30 corresponding to the notches 305. The perforations 307 are available for installation. With other components of the tool box, the seat body 30 is manufactured in an integrated manner to increase the strength and durability of the seat body 30.
[0043] See Figure 16 , 17 As shown, when the cover body 31 of the metal tool box is made in the present invention, a suitable metal plate is first taken for drawing processing, and the mold is integrally stretched at the center of the metal plate to form a corresponding shape of the seat body 30 The cover body 31 is rough. The cover body 31 is formed with a top plate 311 and a side plate 312 with rounded corners. At the same time, there are several grooves 313 formed on the outside of the top plate 311; please refer to Figure 16 , 18 As shown, the rough blank of the cover body 31 is punched again to form a number of perforations 314 on the groove 313 of the rough blank of the cover body 31. The perforations 314 are available for installing other components of the tool box; Refer to Figure 16 , 19 As shown, the edge removal process is carried out, which is to remove the remaining material around the rough blank of the cover body 31 by means of punching and shearing; please refer to Figure 16 , 20 As shown, the trimming process is then performed, which is to first remove the burrs of the arc segments by punching and cutting the top of the side plate 311 of the rough blank of the cover body 31, and then trim and shape the cover body 31 to an appropriate height. Then the burrs on one side of the straight section are removed by stamping and shearing, and a notch 315 is formed at the same time, while the other three sides of the straight section are respectively removed in the same way and trimmed to the same height as the arc section. Furthermore, the cover body 31 is manufactured in an integrated manner to increase the strength and durability of the cover body 31.
[0044] See Figure 21 , 22 As shown, the present invention can be assembled after the base body 30 and the cover body 31 are formed and assembled. The base body 30 and the cover body 31 are assembled and combined with a hinge device 32. A pivoting piece 321 of the hinge device 32 It is fixed to the notch 305 of the base 30 by welding, and the other pivot piece 322 is fixed to the notch 315 of the cover 31 by welding, so that the cover 31 can follow the hinge 32 The pivot 323 is pivoted to open and close, and when the cover 31 is closed, the inner edge of the cover 31 can be used to fit the flange 306 of the seat 30 to ensure that the seat 30 and the cover 31 are accurately aligned. And make the appearance of the tool box flat to match the design of the overall appearance of the tool box, and thereby greatly enhance the beauty of its appearance.
[0045] In summary, the present utility model is indeed a highly practical and progressive design, but the same products and publications have not been disclosed, so it meets the requirements of a patent application and an application is filed in accordance with the law.
[0046] The above specific implementations are only preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art can make changes, modifications or even equivalents to the present invention without departing from the spirit and scope of the present invention, and these changes will fall into the protection scope of the present invention.
