Abstract

The utility model discloses a traceless riveting punch set, which comprises an upper punch and a lower punch, wherein during riveting, a rivet is inserted into a sheet metal part and the sheet metal part is positioned between the upper punch and the lower punch; the upper punch comprises a connecting part and a riveting-pressing part; the connecting part is a cylindrical rod; the riveting-pressing part is a cylindrical stage, and one side close to the sheet metal part is a first riveting-pressing side; a circle of first arc-shaped surface is formed upwards on the edge of the first riveting-pressing side; a hole for accommodating the end part of a rivet is formed in the middle of the lower punch; one side close to the sheet metal part is a second riveting-pressing side; a circle of second arc-shaped surface is formed downwards on the edge of the second riveting-pressing side. By adopting the traceless riveting punch set disclosed by the utility model, section difference on the riveted sheet metal part is prevented, the entire surface is visually flat, and the appearance quality of a product is improved; moreover, the traceless riveting punch set is suitable for all models without changing the structure of an original riveting machine, and is high in generality; furthermore, the sheet metal part does not need to be manually placed horizontally, so that the working efficiency is increased, and the labor intensity of workers is lowered.

Description

Seamless riveting punching head group
Technical field
The utility model relates to a kind of seamless riveting punching head group, belongs to panel beating field.
Background technology
Riveting post riveted is very extensive in whole panel beating, all can use riveting post riveting technology in individual PC, industrial computer, notebook computer, all-in-one, flat panel TV, mobile phone, all kinds of household electrical appliance, all kinds of machine, all kinds of machinery.Along with people are to the improving constantly of appearance requirement, also more and more higher to the surface requirements of product after riveted, current riveting technology can not meet the pursuit of people to product perfect, and seamless riveting punching head group has solved this puzzlement.
Utility model content
For solving the deficiencies in the prior art, thereby the purpose of this utility model is to provide the riveting punching head group that a kind of highly versatile, operating efficiency are high, can realize seamless riveted and improve riveting quality.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Seamless riveting punching head group, comprising: with the fixing upper punch of rivet driver upper arm jumper bar, be fixed on the low punch on rivet driver die shoe, when riveted rivet penetrate in sheet metal component and sheet metal component between upper punch and low punch; Described upper punch comprises connecting portion and riveting portion, and described connecting portion is cylindrical bar, and described riveting portion is cylinder table and is the first riveting face near the one side of sheet metal component, and the edge of the first riveting face upwards forms circle first arcwall face; In the middle of described low punch, being provided with the hole that holds rivet end, is the second riveting face near the one side of sheet metal component, and the edge of the second riveting face forms circle second arcwall face downwards.
Aforementioned connecting portion and riveting portion one-body molded and between there is round-corner transition structure.
Aforementioned the first arc surface and the second arc surface radical length are 2mm, and the difference in height of circular arc end and initiating terminal is 0.2mm.
Usefulness of the present utility model is: seamless riveting punching head group of the present utility model has adopted globoidal structure, makes to there will not be tangent plane offset on the sheet metal component of riveted, and integral surface is visual smooth, has promoted the exterior quality of product; And need not change the structure of original rivet driver, and being applicable to institute's organic type, versatility is good; In addition, while manually placing sheet metal component, without special placement level, improve operating efficiency, reduced workman's labour intensity.

The implication of Reference numeral in figure: 1, upper punch, 2, low punch, 201, hole, 202, the second riveting face, 3, connecting portion, 4, riveting portion, 401, the first riveting face, 5, round-corner transition structure, 6, the first arcwall face, 7, the second arcwall face.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1, seamless riveting punching head group of the present utility model, comprise: with the fixing upper punch 1 of rivet driver upper arm jumper bar, be fixed on the low punch 2 on rivet driver die shoe, when riveted, rivet penetrates in sheet metal component and sheet metal component is placed between upper punch 1 and low punch 2.Wherein, upper punch 1 comprises connecting portion 3 and riveting portion 4, preferably connecting portion 3 and riveting portion 4 is one-body molded and between there is round-corner transition structure 5 as shown in Figure 2.Connecting portion 3 is cylindrical bar, and the edge that riveting portion 4 is the first riveting face 401, the first riveting faces 401 for cylinder table and near the one side of sheet metal component upwards forms a circle the first arcwall face 6 as shown in Figure 3; In the middle of low punch 2, be provided with the hole 201 that holds rivet end, the edge that is the second riveting face 202, the second riveting faces 202 near the one side of sheet metal component forms a circle the second arcwall face 7 as shown in Figure 5 downwards.
As shown in Figure 3 and Figure 5, the first arc surface and the second arc surface radical length a are 2mm, and the difference in height b of circular arc end and initiating terminal is 0.2mm.
When riveted, upper punch 1 and low punch 2 are respectively installed to the corresponding position of rivet driver, open rivet driver and pressure is adjusted to after appropriate value, rivet is penetrated in sheet metal component, then sheet metal component is positioned between upper punch 1 and low punch 2, the hole 201 of low punch 2 is put in one end that rivet is stretched out, and starts rivet driver, and upper punch 1 is pressed into rivet in sheet metal component.Because sheet metal component is artificial placement, cannot ensure complete level, so in riveting process, drift originally can make panel beating surface occur a recessed circle of visual obvious circle; And adopt drift group of the present utility model, owing to having formed arcwall face at the edge of upper punch 1 and low punch 2, even if sheet metal component is not placed level, no matter sheet metal component to which direction tilts, riveted back punching head all terminates in arcwall face, make the curved any tangent plane offset (being circular recessed circle) that excessively there will not be on sheet metal component of vestige extruding, sheet metal component surface is visual smooth, has greatly promoted the exterior quality of product.
More than show and described general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
