Detailed Description
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and embodiments, which are only used for explaining the present invention and are not limited to the protection scope of the present invention.
Examples
As shown in fig. 1, the present embodiment provides a needle bearing cage sizing die, which includes a lower die and an upper die; the lower die comprises a lower die plate 1, the lower die plate 1 is provided with a lower punch fixing plate 4, and a lower punch 9 is arranged on the lower punch fixing plate 4; a female die 8 is also arranged on the outer side of the lower punch fixing plate; the bottom of the female die 8 is provided with a female die holder 6, and the bottom of the female die holder 6 is fixed with a slide block of the linear guide rail 3 arranged on the lower die plate 1; the female die 8 is also provided with a conical ring 16; a first return spring 2 is also arranged between the bottom surface of the conical ring 16 and the lower template 1; conical surfaces are respectively arranged at the matched positions of the female die 8 and the conical ring 16; the upper die comprises an upper die plate 10, the upper die plate 10 is provided with an upper punch fixing plate 12, and an upper punch 13 is arranged in the upper punch fixing plate 12; the upper template 10 is also provided with a pressing ring 11 corresponding to the conical ring 16; when the die is closed, the upper punch 13 and the lower punch 9 together form an inner cavity shaping surface of the retainer 17, and the inner side of the female die 8 forms an outer wall shaping surface of the retainer 17; the top side of the upper template 10 is also provided with a template handle 14; a second return spring 7 is also arranged between the die holder 6 and the lower punch fixing plate 4; a third spring 15 is arranged between the top end of the upper punch 13 and the upper die plate 10; the upper punch 13 is arranged in the upper punch fixing plate 12 in a floating manner; a guide post 5 is also arranged between the upper die and the lower die; one end of the guide post 5 is fixed on the lower template 1, the other end is inserted in the conical ring 16, and the pressing ring 11 is also provided with a guide groove at the position corresponding to the guide post 5.
According to the needle bearing retainer sizing die, when the needle bearing retainer sizing die works, a retainer to be sized is sleeved on a lower punch for positioning, when an upper die moves downwards, the upper punch and the lower punch are combined into a whole working part, then the upper die continues to move downwards, a pressing ring is contacted with a conical ring and moves downwards together, the conical ring pushes a female die to the position of the lower punch along a linear guide rail under the action of a conical surface, and the female die finishes sizing of the retainer under the action of the transverse force; and finally, the upper punch moves out of the retainer and resets under the action of the upper die plate pulled by a third spring, and the retainer shaping process is finished.
According to the needle bearing retainer sizing die, the difficulty encountered by retainer sizing is solved through the application of a split structure and the arrangement of the spring and the linear guide rail, the inner diameter and the outer diameter of the retainer are simultaneously sized, roundness deformation is eliminated, and the rotation flexibility of the bearing is ensured.
The above-mentioned embodiments should not limit the present invention in any way, and all the technical solutions obtained by adopting equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
