Embodiment Construction

[0010] exist figure 1 In the closing preparation stage, two bearings (3) used in pairs are installed in the mounting holes at both ends of the housing (4), and the housing (4) is clamped on the upper mold (2) and the lower mold (6 ), and a long guide pin (5) is provided at the inner hole of the upper mold (2), the lower mold (6) and the bearing (3), through the clamp ( 1) Clamp the housing (4) and the bearing (3) to ensure that the spherical punch points of the closing dies (2) and (6) withstand the outer end surface of the housing (4).

[0011] When using stamping closing, start the press, control the closing mold (2) and (6) to apply the load through the clamp (1), and gradually increase from zero until the specified closing load is reached. At this time, a spherical shape of the specified shape can be obtained. pit. After the pressure is released, reset the closing molds (2) and (6), and then repeat the pressure closing process until the number of spherical pits required ...

Abstract

The invention discloses a closing-in die suitable for a single face or double faces of paired bearings. Closing in is simultaneously conducted on the outer end faces of the two sides of the paired bearings through an upper die body and a lower die body, and the closing in process is simplified. In addition, a long guide pin is arranged in an inner hole of the upper die body and an inner hole of the lower die body and penetrates into two bearing inner holes of the paired bearings at the same time, and the effect that the coaxiality of the bearing inner holes in the two ends before and after closing in is conducted is good can be ensured. When one of the paired bearings does not need to be subjected to closing in, the upper die body or the lower die body can be replaced with a fixing device which is not provided with a spherical punching point, and then single face closing in can be achieved.

Description

technical field [0001] The patent of the invention relates to a single-sided or double-sided spherical punching point closing mold suitable for paired bearings, and is suitable for the closing process of paired bearings. Background technique [0002] The existing bearing closing process is all for closing a single bearing, so for the assembly of a pair of bearings, one end bearing is often closed first, and then the other end bearing is closed. Firstly, this assembly method requires two closing processes, which are relatively complicated; secondly, it is easy to cause the coaxiality of the inner holes of the two bearings of the paired bearings to be relatively poor after closing, and sometimes it is difficult to put on the bolts. Therefore need to improve this traditional closing mold. Contents of the invention [0003] The invention patent provides a single-sided or double-sided spherical punching point closing mold suitable for paired bearings, which can reduce the comp...
