Embodiment
[0020] Embodiment: A kind of manufacturing method of the combined heavy-duty prestressed oil cylinder that splits along the generatrix, it comprises the following steps:
[0021] Step 1: Processing of the inner layer 1: firstly, the steel ingot is forged into a cylinder blank, then its inner, outer diameter and height are roughly machined, then heat treated, and then the inner and outer diameters are semi-finishing, and the inner and outer diameters are Leave a machining allowance: leave a margin of 2-15mm for the inner radius of the inner core cylinder, and leave a margin of 2-20mm for the outer radius;
[0022] Step 2: Machining of the sub-parts 21 in the middle layer: processing the sub-parts 21 in the middle layer along the generatrix to divide flat mutual contact interfaces to the required accuracy;
[0023] Step 3: detachably connect the components 21 of the middle layer, then process the diameters of the inner cylindrical surface and the outer cylindrical surface of the...

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 manufacturing method of 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. 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 cylinders...
