Abstract
A combined plunger type cylinder comprises a combined cylinder body and a plunger. The combined cylinder body is formed by a cylinder sleeve, cylinder rings, a front flange, a cylinder bottom, bolt assemblies and cylinder sleeve sealing pieces. The cylinder rings are arranged on outer cylindrical surfaces of the cylinder sleeve in a stacking mode. The external diameter of the cylinder sleeve is tightly matched with the internal diameters of the cylinder rings. The front flange and the cylinder bottom are respectively matched with the outer cylindrical surfaces at two ends of the cylinder sleeve and are sealed through the sealing pieces to form a cylinder body working cavity. The bolt assemblies are arranged on the outer circumferences of the cylinder rings and enable the front flange, the cylinder rings and the cylinder bottom to be connected into a whole. The combined plunger type cylinder is simple in structure and good in manufacturing manufacturability. A series of giant plunger type cylinders with thrust of 200 MN can be conveniently manufactured. Only one or two plunger type cylinders can meet trust requirements of various heavy duty hydraulic machines. The combined plunger type cylinder can be used as a main hydraulic cylinder of the various heavy duty hydraulic machines, can simplify the equipment structure, and reduces manufacturing difficulty and manufacturing cost.
Description
Technical field
The utility model relates to a kind of hydraulic pressure installation, specifically, relates to a kind of combined type plunger case.
Background technique
The stake plug cylinder is the crucial dynamical element of heavy hydraulic press, hydraulic press.The cylinder body of traditional stake plug cylinder is generally and adopts casting or smithwelding technology to manufacture overall structure.Be subjected to the restriction of forge weight, factors such as welding wall thickness, heat treatment and non-destructive inspection, be difficult to produce the enough big and sufficiently long integrated type plunger case of stroke cylinder bodies of diameter, the normal thrust of every cylinder is generally about 50MN.Therefore the master hydraulic cylinder of heavy hydraulic press, heavy hydraulic press generally all adopts many plunger cases to combine, this make device structure comparatively complicated, increased equipment manufacturing cost and controlled difficulty.
The model utility content
At above-mentioned deficiency of the prior art, the utility model provides a kind of good anufacturability that has, and reduces the combined type plunger case of manufacture difficulty and manufacture cost.
Technical solution adopted in the utility model is:
A kind of combined type plunger case comprises combined type cylinder body and plunger, and described combined type cylinder body is made of cylinder sleeve, cylinder ring, forward flange, cylinder bottom, bolt assembly and liner packing spare; Stacked the cylinder ring on the external cylindrical surface of described cylinder sleeve, cylinder sleeve external diameter and cylinder ring internal diameter closely cooperate; Forward flange, cylinder bottom cooperate with the external cylindrical surface at cylinder sleeve two ends respectively, and by the Sealing sealing, constitute the cylinder body active chamber; The excircle of cylinder ring is provided with bolt assembly, and forward flange, cylinder ring and cylinder bottom are connected.
Described forward flange internal surface is provided with plunger seal assembly and plunger guide part.
The beneficial effect of the relative prior art of the utility model:
The utility model combined type plunger case, simple in structure, have good anufacturability, can produce the serial huge plunger case that thrust reaches 200MN easily; Use one or two plunger cases just can satisfy the thrust requirement of various heavy hydraulic press, can be used as the master hydraulic cylinder of various heavy hydraulic press, can make device structure simplify, reduce manufacture difficulty and manufacture cost.

Embodiment
Followingly with reference to drawings and Examples the utility model is described in detail:
Accompanying drawing 1 as can be known, a kind of combined type plunger case comprises combined type cylinder body and plunger 6, described combined type cylinder body is made of cylinder sleeve 5, cylinder ring 4, forward flange 7, cylinder bottom 1, bolt assembly 3 and liner packing spare 2; Stacked cylinder ring 4 on the external cylindrical surface of described cylinder sleeve 5, cylinder sleeve 5 external diameters and cylinder ring 4 internal diameters closely cooperate; Forward flange 7, cylinder bottom 1 cooperate with the external cylindrical surface at cylinder sleeve 5 two ends respectively, and by the Sealing sealing, constitute the cylinder body active chamber; The excircle of cylinder ring 4 is provided with bolt assembly 3, and forward flange 7, cylinder ring 4 and cylinder bottom 1 are connected; Described forward flange 7 internal surfaces are provided with plunger seal assembly 9 and plunger guide part 8.
Bolt assembly is mainly used to bear, by the hydraulic thrust of the ring surface product moment between plunger outer diameter and the cylinder sleeve external diameter to the forward flange generation; Plunger is installed in the combined type cylinder body by forward flange front end endoporus, and keeps certain interval with inboard wall of cylinder liner, and plunger can to-and-fro motion in cylinder body; Be separately installed with plunger seal assembly and plunger guide part in the forward flange endoporus; Cylinder bottom is provided with attachment hole, for the liquid medium turnover cylinder body that promotes plunger motion.
The utility model combined type plunger case, simple in structure, have good anufacturability, can produce the serial huge plunger case that thrust reaches 200MN easily; Use one or two plunger cases just can satisfy the thrust requirement of various heavy hydraulic press, can be used as the master hydraulic cylinder of various heavy hydraulic press, can make device structure simplify, reduce manufacture difficulty and manufacture cost.
