SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcomes the defects of the existing rivet head structure and provides an embedded rivet head structure which can reduce the cost and is convenient to replace.
The utility model adopts the technical proposal that: an embedded rivet head structure comprises a rivet head parent body and a rivet head daughter, wherein a hole is formed in the rivet head parent body along the length direction of the rivet head parent body, and a first pin hole perpendicular to the axis of the hole is formed in one end of the rivet head parent body; one end of the rivet head sub-body is provided with a cavity, the other end of the rivet head sub-body is provided with a shaft which can be embedded into the hole, a second pin hole which is vertical to the length direction of the shaft is formed in the shaft, and the lock pin penetrates through the first pin hole and the second pin hole to fixedly connect the rivet head parent body and the rivet head sub-body.
In the scheme, the embedded rivet head structure is composed of the rivet head parent body and the rivet head daughter body which are detachably connected, when the rivet head daughter body is damaged due to overlarge riveting force, the rivet head daughter body can be replaced, and compared with the existing whole rivet head structure, the embedded rivet head structure can improve the utilization rate of the rivet head parent body and save the cost.
Preferably, the cavity is in a round table shape, and the bottom of the cavity is rounded.
Preferably, the radius of the round angle is 1.5mm, and the included angle between the generatrix of the circular truncated cone and the axis of the circular truncated cone is 13 degrees; the end face of the rivet head sub-body, provided with the cavity, is an inclined plane, and the included angle between the inclined plane and the end face of the opening end of the cavity is 10 degrees. The design of the rivet head sub-body and the cavity can improve the forming rate of the die.
Preferably, one side wall of the hole is a plane side wall, and the surface of the shaft is provided with a first plane matched with the plane side wall so as to prevent the rivet head daughter and the rivet head parent body from rotating.
Preferably, the rivet head parent body is cylindrical, and a second plane corresponding to the plane side wall is arranged on the outer wall of the end, provided with the first pin hole, of the rivet head parent body. The second plane is provided with and does benefit to the quick alignment die parent of die daughter when the assembly, practices thrift the assemble duration.
Preferably, the outer wall of the rivet head parent body is provided with a groove along the circumferential direction. When the rivet head structure is taken down from the clamping equipment, the clamp can be placed in the groove, and the clamp is prevented from sliding.
The utility model has the advantages that: the embedded rivet head structure of the utility model can realize the quick replacement of the rivet head daughter, reduce the riveting time, improve the utilization rate of the rivet head mother body and reduce the loss cost; the unique design of the die cavity can reduce the risk of unstable molding quality in the riveting process.
