Abstract

The utility model discloses a non-rivet riveted structure for metal plates and relates to a non-rivet riveted structure for two aluminum plates. Two layers of metal plates are two layers of aluminum plates which are different in thickness and are formed by cold extrusion through matched dies, the riveted position of the two aluminum plates is the connection point at which the thinner metal plate is embedded in the other metal plate, and the riveted position of the two aluminum plates is extruded out of the outer side surface of the thicker metal plate, thus forming a structure with the interior embedded with the connection point, wherein the structure has certain tensile strength and shearing strength. The non-rivet riveted structure has the advantages of firmness in connection, low cost and the like.

Description

Panel beating does not have the rivet structure

Technical field

The utility model discloses a kind of panel beating does not have the rivet structure, divides by International Patent Classification (IPC) (IPC) to belong to a metallic plate connection type manufacturing technology field, and especially relating to a kind of two metallic plates does not have riveting riveted joint structure.

Background technology

Present metal plate material connected mode generally is welding, bolt connection, rivet etc.; Aforesaid way becomes the connected mode of mechanical manufacturing field sheet metal component commonly used, and in automobile hatch door manufacture process, its accessory such as lock box etc. are by two-layer aluminium sheet machine-shaping; And two-layer aluminium sheet is affixed through rivet; But owing to need rivet and specific purpose tool in forming process, not only production efficiency is low, but also the rivet that will be scheduled to cooperate causes material and cost of labor to improve.

Summary of the invention

Deficiency to prior art; The utility model provide a kind of rational in infrastructure, connect reliable metal plate and do not have the rivet structure more; Mould through being equipped with mutually is cold extrusion shaped with the aluminium sheet of two-layer different-thickness, forms the metal plate material built-in structure that tie point is inlayed in the inside with certain tension and shearing strength.

For achieving the above object, the utility model is realized through following technical scheme:

A kind of panel beating does not have the rivet structure, comprises the double layer of metal plate, and two metallic plates do not have rivet and tightly become one, the tie point that riveted joint place of two metallic plates is inlayed in another metallic plate for a metallic plate wherein.

Further, described double layer of metal plate is the metallic plate of two-layer different-thickness, the tie point that riveted joint place of two metallic plates is inlayed in another metallic plate for thin metallic plate.

Further, the aluminium sheet that described two metallic plates are two-layer different-thickness is cold extrusion shaped, and the tie point of two aluminium sheets forms mosaic texture and do not penetrate the aluminium sheet that is embedded into when riveted joint, and riveted joint place protrudes in the aluminium sheet lateral surface that is embedded into.

It is cold extrusion shaped with the aluminium sheet of two-layer different-thickness that the utility model utilizes metallic character to pass through particular manufacturing craft, forms the structure that tie point is inlayed in the inside with certain tension and shearing strength, the utlity model has following beneficial effect:

1, the utility model is because two aluminium sheets are inserted cold extrusion shaped, and its tie point (riveting point) is solid and reliable;

2, be one because the utility model has riveting riveted joint with aluminium sheet, omitted traditional riveted joint usefulness rivet, do not have consumption of raw materials and do not need aid;

3, the utility model is to utilize metallic character, and is directly cold extrusion shaped, surmounted metal material limitation and thickness limitation;

4, the utility model two aluminium sheets can form round dot and are connected with huge point, and do not have thermal stress at join domain, thereby can not damage the protective layer of surface of the work, and do not need in advance or afterwards the formula part to be handled, and allow interlayer and are connected with multilayer;

5, the no rivet used of the utility model, its good work environment does not have the discharging of dust toxic smoke, does not have noise, and simple to operate, consumption is low, maintenance cost is few.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Embodiment: a kind of panel beating does not have the rivet structure, comprises the double layer of metal plate, and two metallic plates do not have rivet and tightly become one, the tie point that riveted joint place of two metallic plates is inlayed in another metallic plate for a metallic plate wherein.

See also Fig. 1,2, be the signal of aluminium alloy car luggage compartment door, lock box 2 is installed on the hatch door 1; Lock box 2 is by the machine-shaping of inside and outside double layer of metal sheet material; To be that the

aluminium sheet

3,4 of two-layer different-thickness is cold extrusion shaped be one to two metallic plates, and the tie point that riveted joint place of two aluminium sheets is inlayed in another metallic plate for thin metallic plate is as shown in Figure 3; When riveting, form blind hole structure 34 at above-mentioned tie point, and riveted joint place protrudes in than the slab lateral surface.

The tie point of two aluminium sheets of the utility model forms mosaic texture and does not penetrate the aluminium sheet that is embedded into when riveted joint, and riveted joint place protrudes in the aluminium sheet lateral surface that is embedded into.

It is cold extrusion shaped with the aluminium sheet of two-layer different-thickness that the utility model utilizes metallic character to pass through particular manufacturing craft, forms the structure that tie point is inlayed in the inside with certain tension and shearing strength, has advantages such as being connected firmly, practicing thrift cost.

The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
