A press for manufacturing precision bearings

Abstract

The invention discloses a pressure machine for precision bearing manufacturing. The pressure machine structurally comprises a hydraulic box, a display screen, a detection head, a wheel pair clamping mechanism, a support, a lathe bed and a throttling pipeline, wherein a hydraulic cylinder is vertically installed on one side of the top end surface of the lathe body, the display screen is installed on the hydraulic box, the wheel pair clamping mechanism is installed on the top end surface of the lathe body, the wheel pair clamping mechanism is right opposite to the hydraulic box, the detection head is installed on one side of the wheel pair clamping mechanism through the support, the hydraulic box is mainly provided with a main hydraulic cylinder, an auxiliary hydraulic cylinder and an oil return system, and the throttling pipeline is one part of the oil return system. According to the pressure machine, through the cooperation of clamping grooves and protrusions, a flange ring and the throttling pipeline can slide relative to each other, then a first diaphragm clack and a second diaphragm clack are in opposite friction with the throttling pipeline and a triangular ring in turn so as to remove asphalt caused by differential pressure of the first diaphragm clack and the second diaphragm clack, and then the oil return amount is prevented from reducing due to asphalt accumulation.

Description

technical field [0001] The invention relates to the field of bearing manufacturing, in particular to a press for precision bearing manufacturing. Background technique [0002] During the processing of the bearing, it needs to go through the process of pouring-mold forming-rough blank-processing-finishing-finished product, and the press is the main machine for the press-fitting machine to process the bearing, and flow distribution will occur during press-fitting When the flow rate is uneven, the force of the pressure will change, and the stress in the outer ring and inner ring that is pressed out will be insufficient, and accidents will easily occur in the later use. The main reason for the uneven flow is that the pressure oil passes through When the throttle gap occurs, pressure loss will occur, which will cause the oil temperature of the intelligent press to rise locally, and the oil will be oxidized and deteriorated. Adhering to the wall, reducing the flow area, and even ...
