Abstract
The invention relates to a rivet head for assembling and riveting a hinge assembly. The rivet head is fixed on a riveting apparatus for fixedly riveting the head of a pin. The rivet head comprises a riveting part, a riveting head body and a fixing part. The riveting part, the rivet head body and the fixing part are orderly connected. A cavity is formed on the head of the riveting part. While riveting, the riveting part presses and contacts the head of the pin. In the compressional deformation of the head of the pin, the cavity wraps the deformed and expanded part, so that the head of the pin regularly deforms and expands, thereby preventing the head of the pin from cracking. As compared with the prior art, the rivet head of the invention has advantage of beautiful appearance after riveting the head of the pin.
Description
Technical field
The present invention relates to a kind of mechanized equipment equipment, especially relate to a kind of die for the riveted joint of hinge general assembly.
Background technology
At present, some hinge needs to use bearing pin two one-piece unit together, and bearing pin head needs riveting to fix, and riveting rear pin shaft head easily ftractures, and affects product appearance and performance.
Such as application number be 201310154919.1 Chinese patent disclose a kind of Rivet head device, it is mobilizable is connected on the riveter body corresponding with Rivet head device; Rivet head device comprises: fixed block and the die body be flexibly connected with fixed block; Die body comprises the first projection extended from die body, multiple second projection, and from the 3rd projection that the first projection extends.Compared with prior art, Rivet head device provided by the invention is by arranging multiple equally distributed second projection, making Rivet head device treat riveting equipment part Pressing Deformation can formation rule and firmly bulk deformation gradually, equipment to be riveted is easily stamped shaping, and structure is simple, improves the operating efficiency of riveter body.
If but this Rivet head device is used for the riveting of hinge general assembly, then in the process of riveting, die squeeze pin shaft head, make, in bearing pin head expansion process, the phenomenon of bearing pin dehiscence in the head can occur, so affect attractive in appearance, two come also can hinder hand.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of prevent bearing pin dehiscence in the head for hinge general assembly riveted joint die.
Object of the present invention can be achieved through the following technical solutions:
A kind of die for hinge general assembly riveting, this die is fixed on riveting press equipment, and for fixing bearing pin head riveting, described die comprises riveting portion, die body and fixed part, described riveting portion, die body are connected successively with fixed part, and described riveting size portion is provided with die cavity;
During riveting, riveting portion presses to and contact plug shaft head, and in bearing pin head extrusion process, die cavity wraps distortion and expands position, the regular distortion of bearing pin head is expanded, and then prevents bearing pin dehiscence in the head.
The diameter of described die cavity opening is greater than bearing pin head diameter.
Described fixed part is provided with screw holddown groove, and described screw holddown groove is connected with riveting press equipment.
Described riveting portion, die body and fixed part are one-body molded.
The material of described die is Cr12MoV.
Described die cavity is truncated cone-shaped or segment-shaped.
Described riveting portion is greater than die body.
Compared with prior art, the present invention has the following advantages:
1) the bearing pin head after die cavity can make riveting does not ftracture.
2) die cavity opening is greater than bearing pin head and can holds bearing pin head.
3) die can be fixed on riveting press equipment by screw holddown groove easily.
4) the one-body molded production cost that can reduce die.
5) material of Cr12MoV can make bearing pin head burr reduce.
6) truncated cone-shaped or segment-shaped can make riveting rear pin shaft nose shape attractive in appearance.
7) riveting portion volume is large, riveting better effects if.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment one:
A kind of die for hinge general assembly riveting, this die is fixed on riveting press equipment, for fixing bearing pin 4 head riveting, as shown in Figure 1, die comprises riveting portion 1, die body 2 and fixed part 3, riveting portion 1, die body 2 are connected successively with fixed part 3, and riveting portion 1 head is provided with die cavity 11;
During riveting, riveting portion 1 presses to and contacts bearing pin 4 head, and in bearing pin 4 head extrusion process, die cavity 11 wraps distortion and expands position, the regular distortion of bearing pin 4 head is expanded, and then prevents bearing pin 4 dehiscence in the head.
The diameter of die cavity 11 opening is greater than bearing pin 4 head diameter, but the degree of depth is less than the length of bearing pin 4 head.
As shown in Figure 2, fixed part 3 is provided with screw holddown groove 31, and screw holddown groove 31 is connected with riveting press equipment.
Riveting portion 1, die body 2 and fixed part 3 are one-body molded, can reduce the cost producing such die like this.
The material of die is Cr12MoV, has hardness, needs quenching, modifier treatment, existing hardness, not yielding, flexible again, not easy fracture.
Die cavity 11 is truncated cone-shaped or segment-shaped, and its face, little bottom surface is greater than the area of bearing pin 4 head upper surface.
Riveting portion 1 is greater than die body 2.
After bearing pin 5 encounters die riveting portion 1, be squeezed and start distortion until be full of the die cavity 11 in whole die riveting portion 1, die cavity 11 effectively can control bearing pin 4 head and carry out regular distortion, is that bearing pin 4 head state is regular stable, can not produces overlap and cracking.
Embodiment two:
In the present embodiment, a kind of something in common no longer describes with embodiment, only describes different part a kind of from embodiment.
As shown in Figure 3, in the present embodiment, riveting portion 1 is greater than die body 2, and whole die center of gravity is on the lower side, like this can by better riveting effect.
Each boundary of this external die is polished into round and smooth structure, more comfortable when holding.
