When the deep groove ball bearing adopts the solid cage; the grade adopts the long rivet riveted two-half cage. The rivet has the same shape as the short rivet; the rod has a long dimension; the rivet head has a low height. The bearing is riveted with the long rivet; because of the cage 7L The effect of the difference of the difference and the inclination of the rivet hole; the method of one-time forming can be used like a riveted stamping cage; the rivets in a set of bearings are all riveted; and it is necessary to use an electric riveting machine to rive each rivet one by one. The long rivet mold consists of upper and lower punches. The upper punch is the working punch; the high temperature high pressure is accepted when riveting; the high speed steel or hard alloy is used to make the lower punch; the lower punch is the support punch; Conductivity; excellent touch with rivet head; made of high quality low carbon steel or brass. Electric rivet; upper punch is installed in the fixture under the cylinder of electric riveting machine; factory punch is installed on the working table of electric riveting machine Upper; corresponding to the orientation of the upper punch. When riveting. The rivet rod is on; the upper and lower punches are compared with a rivet; the current is turned on; the upper end of the rivet rod is heated to a proper temperature; then the upper punch is dropped; the rivet head is formed; the cage is riveted.
The solid cage used for deep groove ball bearings; usually consists of two pieces; the two half cages are processed together as a whole. In particular, the ball pockets and rivet holes must be processed together; the quality is ensured. When two pieces of cage are processed After completion; draw the matching line at the inner or outer diameter of the complete cage; bundle it with a rope; so that it can be installed together and the holes are good. When the bearing is installed; first find the matching line orientation; The last rivet is used as a symbol; in order to ensure the orientation of the two retainers; as long as this is the case; the ability to ensure the rotational flexibility and appearance quality of the bearing is required.
