Problems solved by technology

[0003] In the prior art, maintenance personnel are required to first remove the tapered roller from the equipment, install the tapered roller on a lathe or other auxiliary tooling, use a welding torch to carry out surfacing welding on it, and then put it back into the rolling ring after repairing machine, in which the disassembly and assembly of the tapered rollers has the disadvantage of taking a long time, which in turn leads to an increase in repair time

Embodiment 1

[0034] Please refer to figure 1 , in order to solve the above problems, the present invention proposes an on-line surfacing device for tapered rollers of a ring rolling machine, including a support 1, a connecting piece 2 and a welding torch 3; the support 1 is installed on the small diameter end of the tapered roller 4 and The tapered rollers 4 rotate synchronously, one end of the connecting piece 2 is installed on the supporting piece 1 and moves linearly along the supporting piece 1 under the rotation drive of the supporting piece 1, and the other end of the connecting piece 2 extends to The to-be-surfacing position of the tapered roller 4 , the welding torch 3 is installed on the end of the connecting member 2 away from the support member 1 and its nozzle faces the to-be-surfacing position of the conical roller 4 . Install the support member 1 on the tapered roller 4 and rotate synchronously with the tapered roller 4, drive the connecting member 2 to move linearly along th...

Embodiment 2

[0038] Please refer to figure 1 , the support member 1 is connected to the center of the small-diameter end, and the support member 1 is arranged along the axial direction of the tapered roller 4 . The tapered roller online surfacing device of the ring rolling machine also includes a nut 5; the support 1 is a screw; the nut 5 is connected to the support 1 and can move linearly along the rod of the support 1; The end of the connector 2 away from the welding torch 3 is connected to the nut 5 . The tapered roller online surfacing device of the ring rolling machine also includes a limit rod 6; the end of the limit rod 6 is connected to the nut 5, and the limit rod 6 is erected on the frame of the ring rolling machine to The rotation of the connecting piece 2 and the welding torch 3 is restricted. Wherein, the nut 5 is a thickened nut, which can improve the connection stability, and further can improve the stability and uniformity of the surfacing.

Embodiment 3

[0040] Please refer to figure 1 , the on-line surfacing device for the tapered roller of the ring rolling machine also includes a distance screw 7; The outer wall of the tapered roller contacts, and the end of the connecting piece 2 away from the welding torch 3 is hinged to the nut 5 . By adjusting the protruding length of the distance screw 7 on the connecting piece 2, the nozzle of the welding torch 3 does not come into contact with the outer wall of the tapered roller 4 all the time, so as to ensure that the welding torch 3 can work normally And the surfacing effect of the welding torch 3.

Abstract

The invention provides an on-line surfacing device for a cone roller of a ring rolling machine. The on-line surfacing device comprises a supporting piece, a connecting piece and a welding gun, wherein the supporting piece is installed at the small-diameter end of the cone roller and synchronously rotates along with the cone roller, one end of the connecting piece is installed on the supporting piece and linearly moves along the supporting piece under rotation driving of the supporting piece, the other end of the connecting piece extends to the position to be subjected to surfacing of the cone roller, the welding gun is mounted at the end, far away from the supporting piece, of the connecting piece, and a spray head of the welding gun faces the position to be subjected to surfacing of the cone roller. According to the technical scheme, the supporting piece is installed on the cone roller and synchronously rotates along with the cone roller, the connecting piece can be driven to linearly move along the supporting piece, then the welding gun can linearly move in the generatrix direction of the cone roller, without the need for detaching the cone roller from the ring rolling machine and installing the cone roller on a lathe or other auxiliary tools, the outer wall of the cone roller can be automatically welded on line, and then the repairing time is shortened.

Description

technical field [0001] The invention relates to the technical field of repairing ring rolling machines, in particular to an online surfacing device for ring rolling machine cone rollers and an online surfacing method for ring rolling machine cone rolls. Background technique [0002] The rolling of the workpiece by the ring rolling machine is realized by two tapered rollers, and the tapered rollers are easy to wear parts. Excessive wear will lead to the reduction of the processing accuracy of the ring parts and the unevenness of the end surface of the ring parts. Therefore, the cone Rollers need to be repaired every six months or so. Because the frequency of use of the small diameter end of the tapered roller is higher than that of the large diameter end, the wear of the small diameter end is more severe than that of the large diameter end, so the overall wear of the tapered roller has irregular characteristics. Considering the irregularity of the overall wear of the tapered...
