Embodiment

[0020] Embodiment: A combined heavy-duty prestressed oil cylinder split along the generatrix, including an inner layer 1, a middle layer 2 and an outer layer 3; the inner layer 1 is an integral core, and the middle layer 2 is composed of at least two A combined cylinder composed of sub-parts 21 with axial side walls attached to each other (the sub-parts are combined into a cylinder to facilitate processing and assembly), the middle layer 2 is sleeved on the outer side of the inner layer 1, and the inner wall of the middle layer 2 is attached to the outer wall of the inner layer 1. The outer layer 3 is a steel wire winding layer, the outer layer 3 is sheathed on the outer side of the middle layer 2 , and the inner wall of the outer layer 3 is attached to the outer wall of the middle layer 2 .

[0021] The number of sub-components 21 of the middle layer combination is between two and twenty.

[0022] The number of sub-pieces 21 in the middle layer is four.

[0023] The overall ...

Abstract

The invention discloses a manufacturing method of a combined heavy-duty prestressed oil cylinder split along a bus bar. A processing method of the oil cylinder comprises the following steps of: performing forging, rough processing and semi-finishing on a steel ingot to obtain an inner layer barrel which is consistent with a requirement; processing a middle layer component; detachably and fixedly connecting the inner layer barrel with the middle layer component; performing finish machining on the outer diameter of the inner layer according to the inner diameter of the middle layer; splicing the middle layer component on the outer side of the inner layer (outer cylindrical surface); and winding and fastening the outer side of the middle layer with a steel wire. By adopting the combined heavy-duty prestressed oil cylinder, the tangential prestressing force of the barrel is enhanced, the axial bending of the barrel is reduced, and the barrel is prevented from being damaged by excessive bending stress. The barrel produced with the manufacturing method has short manufacturing cost and period, is safe and reliable, has long service life, and can be manufactured in medium and small machinery factories.

Description

technical field [0001] The invention relates to a heavy-duty ultra-large-diameter ultra-high-pressure container (oil cylinder) and a manufacturing method thereof, in particular to a combined heavy-duty prestressed oil cylinder split along a generatrix used for the ultra-high-pressure main work of a heavy-duty hydraulic machine and a manufacturing method thereof. Background technique [0002] Heavy-duty axisymmetric ultra-high pressure vessels are widely used in various types of heavy-duty hydraulic presses, such as heavy-duty die forging for aviation, heavy-duty extrusion of nuclear power pipelines, heavy-duty free forging and other hydraulic presses, and cold and hot isostatic ultra-high pressure (1500-4000 atmospheres) for heavy-duty nuclear materials. Hydraulic cylinders and pressure-bearing cylinders of hydraulic presses are key components in the heavy machinery industry. It can be said that without heavy axisymmetric ultra-high pressure vessels, cylinders and hydraulic ...
