Embodiment Construction
[0012] The present invention is described below in conjunction with accompanying drawing.
[0013] The structure of the staple die of the present invention is as attached figure 2 As shown, the punch body 1 is included; the middle of the punch body 1 is provided with a screw through hole 2; the lower end of the punch body 1 is provided with a screw rod 3 and a positioning rod 4; The inner recess is a plane, which is used for binding flat-head rivets, which can ensure the verticality of the rivets in the nailing die, and effectively prevent bad situations such as crooked riveting and riveting deviation; the lower end surface of the positioning rod 4 is arc-shaped, and An elastic material 5 is arranged on the lower end surface, which is beneficial to prevent the wave-shaped cage from being deformed during operation.
[0014] attached figure 2 It is a schematic diagram of the structure of the working state after the punch of the present invention is installed on the nailing d...

Abstract
The invention discloses a terrace die for a rivet installing die. The terrace die for the rivet installing die comprises a terrace die body; a rivet pressing rod and a locating rod are arranged at the lower end of the terrace die body; the concave part of the lower head face of the rivet pressing rod is a plane used for binding a flush head rivet; elastic material is arranged at the lower head face of the locating rod. The terrace die for the rivet installing die is arranged on a wave-shaped retainer binding die, the structure is simple, and the design is reasonable; the plane design of the concave part of the lower head face of the rivet pressing rod is capable of guaranteeing the perpendicularity of a rivet in the rivet installing die, and the riveting quality is effectively improved; the elastic material at the lower head face of the locating rod is good for preventing the wave-shaped retainer from deformation due to pressing when working, and therefore, the production efficiency is improved, and the bearing product quality is guaranteed.
Description
technical field [0001] The invention relates to a female mold structure of a nailing mold, in particular to a punch for a nailing mold with good riveting effect and high production efficiency. Background technique [0002] Deep groove ball bearings are composed of corrugated cages, rolling elements, inner rings and outer rings. The wave-shaped cage must be riveted during assembly, so that the two halves of the cage can be firmly riveted together to maintain it. In the prior art, when assembling the bearing, it is necessary to mix the ball evenly after loading the ball, fasten the two halves of the cage, then insert the rivets into the rivet holes of the cage one by one, fasten the rivet die, and send it to the punching machine for stamping. low efficiency. During the production process of the corrugated cage in the prior art, crooked riveting, biased riveting and lack of nails often occur, which affect the production efficiency and product quality of the bearing. Therefor...
