A bearing bush hydraulic flanging machine

Abstract

The invention discloses a bearing bush hydraulic flanging machine. A numerical control system is in pilot connection with a first hydraulic mechanism, a second hydraulic mechanism, a third hydraulic mechanism and a fourth hydraulic mechanism, a hydraulic cylinder supplies oil for the first hydraulic mechanism, the second hydraulic mechanism, the third hydraulic mechanism and the fourth hydraulic mechanism respectively through oil stations, an active plate is arranged, the fourth hydraulic mechanism is fixed above the active plate and is telescopically connected with a top head, the bottom of the top head is provided with a projection, the third hydraulic mechanism is telescopically connected with the active plate, the active plate is respectively and movably connected with two groups of check blocks through two groups of springs, a limiting block is clamped by the two groups of check blocks and provided with a groove for containing a bearing bush in a matching way, the first hydraulic mechanism is telescopically connected with a first pressure plate, the second hydraulic mechanism is telescopically connected with a second pressure plate, and the first pressure plate and the second pressure plate are respectively arranged on opposite sides of the active plate. The invention aims at providing the bearing bush hydraulic flanging machine which enables the machining process of the bearing bush to be safer and machined products to be finer, and is finally used for finalizing the bearing bush.

Description

technical field [0001] The invention specifically relates to a bearing bush hydraulic flanging machine. Background technique [0002] The bearing is one of the key components of the steam turbine. Under the lubricating and cooling effect of the circulating lubricating oil, it supports the heavy-duty and high-speed running steam turbine rotor. The bearing bush is one of the important components of the bearing. The part is a tile-shaped semi-cylindrical surface, whose function is to bear the force exerted by the journal, keep the oil film stable, make the bearing work smoothly and reduce the friction loss of the bearing. The working principle of the bearing pad requires the bearing pad to have the following characteristics. First, the bearing pad needs to be made of high-temperature resistant materials so that the bearing pad can withstand high temperature; secondly, the inner surface of the bearing pad needs to be polished to be smooth enough to minimize the friction between ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are many equipments for forming bearing pads. However, due to the special shape of the bearing pads, feeding becomes a big problem. Because the operator is required to operate in the operating area, it leads to safety accidents. Due to the special shape of the bearing pads, it is difficult to It is fixed, resulting in poor processing effect of the bearing bush during processing, which needs to be solved urgently
