Description

Pit structure capable of adjusting depth on sheet metal shell

Technical Field

The utility model relates to mechanical panel beating assembly field, concretely relates to realize pit structure of adjustable degree of depth on the panel beating casing.

Background

As is well known, the pit structure on the traditional sheet metal shell is generally formed by stamping and indenting the sheet metal shell through a special die, and comprises two modes of stamping forming and stamping half-shearing, wherein the stamping forming pit is generally used for increasing the height or strength of the sheet metal shell, and the like, and has low requirements on the appearance precision and depth, but a certain stamping inclination is required; and the pit of punching press half-shear all is higher to the requirement of appearance precision and degree of depth, and its degree of depth usually does not exceed two-thirds of sheet metal casing material thickness, otherwise can influence the pit intensity after the shaping. At present, a pit which is of a straight wall type and has the depth larger than the thickness of a sheet metal shell material is required to be formed on a sheet metal shell in many occasions and is used for mounting a decorative plate, a display window and the like. Because can't adopt conventional mould stamping forming or punching press half to cut the mode and realize pit structure, consequently, the technical scheme of a straight wall formula, and the degree of depth is greater than the pit structure of panel beating casing material thickness of urgent need research and development.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the pit structure is of a straight-wall structure, the depth of the pit structure is larger than the thickness of a material, and the depth of the pit structure can be adjusted on a sheet metal shell.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the method comprises the following steps: be provided with the panel beating casing of trompil, be provided with the corresponding packing ring of trompil of panel beating casing and with packing ring matched with bottom plate, the packing ring sets up the inboard edge of the trompil on meal Jin Keti, the bottom plate laminating at the back of packing ring, form the pit.

As a preferred scheme, in the pit structure for realizing adjustable depth on the sheet metal shell, the specific installation mode of the gasket and the bottom plate is as follows: the sheet metal shell around the edge of its trompil be provided with a plurality of pressure riveting screw, bottom plate and packing ring on seted up with pressure riveting screw matched with installation via hole, pressure riveting screw pass the installation via hole on packing ring and the bottom plate in proper order to lock solid with the nut.

As a preferred scheme, in the pit structure for realizing the adjustable depth on the sheet metal shell, the base plate is a sheet metal base plate.

As a preferred scheme, in the pit structure for realizing adjustable depth on the sheet metal shell, the gasket is a plastic gasket.

As a preferred scheme, in the pit structure for realizing adjustable depth on the sheet metal shell, the gasket is a plastic film gasket.

As an optimal scheme, in the pit structure for realizing the adjustable depth on the sheet metal shell, the opening on the sheet metal shell is a square opening, and correspondingly, the opening on the gasket is a square opening.

The utility model has the advantages that: the utility model adopts the combination of the bottom plate, the gasket, the pressure riveting screw and the nut to form the pit structure, the side wall corner cleaning has no stamping inclination, and the thickness of the sheet metal shell material and the thickness of the gasket are superposed to form the pit depth, thus realizing the straight wall type pit structure without a die, having more flexible and convenient manufacture and reducing the processing cost; in addition, the depth of the pit can be changed by selecting gaskets with different thicknesses, so that the depth of the pit can be adjusted, and the application prospect is wide.

Detailed Description

The following describes in detail a specific embodiment of a pit structure for realizing an adjustable depth on a sheet metal shell, taking a square pit as an example, with reference to fig. 1 to 6.

As shown in fig. 1 to 5, realize pit structure of adjustable degree of depth on the panel beating casing, include: the sheet metal shell comprises a sheet metal shell 1 provided with a square opening 11, a plastic film gasket 3 provided with a square opening 31 corresponding to the square opening 11, and a sheet metal bottom plate 2 matched with the plastic film gasket 3, wherein a plurality of press riveting screw holes 12 are formed in the sheet metal shell 1 around the square opening 11, and press riveting screws 4 are arranged in the press riveting screw holes 12 from the outer side of the sheet metal shell to the inside; the sheet metal base plate 2 and the plastic film gasket 3 are respectively provided with mounting through

holes

22 and 32 which correspond to the riveting screws on the sheet metal shell 1 one by one, the plastic film gasket 3 is arranged at the edge of the square opening 11 of the sheet metal shell 1 from the inner side of the sheet metal shell 1, and the sheet metal base plate 2 is arranged at the back of the plastic film gasket 3 from the inner side of the sheet metal shell 1 to form a pit; and after the pressure riveting screw 4 sequentially penetrates through the corresponding mounting through hole 32 on the plastic film gasket 3 and the corresponding mounting through hole 22 on the sheet metal base plate 2, the plastic film gasket 3 and the sheet metal base plate 2 are fixed on the sheet metal shell 1 by locking (locking and fixing) the plastic film gasket 3 and the sheet metal base plate 2 by using a nut 5.

In practical application, through selecting the plastic film packing ring 3 (usually for the PC material) of different thickness, can form the pit of the different degree of depth very conveniently. As shown in fig. 5 and 6, it is assumed that: the material thickness of panel beating casing 1 is 1.2mm, needs form the pit that degree of depth D3 is 1.5mm in the square trompil 11 department of panel beating casing 1, then can select thickness D1 to be 0.3 mm's plastic film packing ring 3.
