Detailed Description

As shown in fig. 2 to 6, the invention provides a joint bearing rolling tool, which mainly comprises a pressure connection tool 1, a rolling head 2, a rolling cushion block 3 and a cushion block 4; cushion 4 is the rolling tool bearing body, place in press mesa central point and put, according to different bolt spare joint bearing sizes, design different rolling cushion 3, rolling head 2, the rolling cushion can be dismantled, change, in order to prevent that the cushion is rotatory, through pin joint between rolling cushion 3 and the cushion 4, rolling head 2 frock has different specification rolling grooves, rolling groove is located rolling head bottom, use in groups with rolling cushion 3, the bolt spare is placed between rolling head 2 and rolling cushion 3, through the rotation of rolling head 2, pressure, accomplish the rolling operation, pressure connection frock 1 is connected with the press pressure head, make pressure transmit to rolling head 2 through the frock, accomplish the pressure operation, pressure connection frock inside has a thrust bearing, can accomplish the rolling head 2 rotation effect of pressure in-process.

The pressure connection frock is mainly to connect the press, and transmission pressure effect simultaneously mainly includes press connector 5, thrust bearing 6, rotatory pressure head 7, threaded connection, and wherein press connector 5 is connected with the press, and the produced pressure of press passes through thrust bearing 6 and transmits to rotatory pressure head 7, then transmits to the pressure equipment frock on, because of press connector 5 can not rotate, so the centre increases thrust bearing 6 and prevents to damage the press head.

The roll extrusion frock mainly includes

rolling head

2, 3 two parts of roll extrusion cushion, rolling head 2 main effects is connected with the V type groove of bolt spare, pressure is applyed to rolling head 2, rotatory rolling head 2 simultaneously, reach bolt spare V type groove binding off purpose, bolt spare is placed on roll extrusion cushion 3 simultaneously, the fixed axle external diameter size that rolling head 2 stretches out is the same with the joint bearing hole, guarantee bolt spare center and 2 center coincidence of rolling head, prevent to press partially, roll extrusion cushion 3 cooperatees with cushion 4, for adapting to the rolling of different model bolt spare, only need change the rolling head 2 and the roll extrusion cushion 3 of different models can, the commonality of frock has been improved, the convenience of operation. Wherein the joint bearing is rolled into the bolt piece.
