Abstract
The present invention relates to a production technology of composite material members and a cylinder jacket of a well drilling pump. The production technology can be used for manufacturing members that different mechanical property material hardness can be obtained on one member, and belongs to the technical field of material machining. The present invention alters the machining method that surface electroplating and surface spray welding are used for manufacturing members that different hardness can be obtained on one member. The present invention adopts a method that different materials are cast in a rotary mould in a molten state to achieve the technical purpose that the hardness of the inner surfaces and the hardness of the outer surfaces of the members are different. Because two kinds of materials of the present invention are cast in a molten state, a transitional fusion layer is formed between the two kinds of the materials, the combination is firm, the shedding can not occur, a worn-out member can be heated to the molten state for machining and use.
Description
A kind of production technology of composite element and cylinder sleeve of drilling pump are used for obtaining the manufacturing of the member of different mechanical performance material hardnesses on same member, belong to forming materials technology field.
In the prior art, a kind of material is generally all adopted in the moulding of member, the processing method that need obtain the member of different mechanical performance hardness on same member mainly contains electroplating surface and surface spraying weld, the shortcoming of these treatment process mainly is: the thickness of the cementation zone of plating is very limited, be difficult to satisfy the condition of work bad working environment, though can reach the thickness requirement of hardened layer in the technology of the surface spraying weld Hardmetal materials of basic component, but tend to occur combine not firm problem between hardened layer and the member basic material layer, and therefore cause product in use, the problem that hardened layer comes off; Patent No. a kind of rich chromium cast iron mud slurry pump cylinder jacket that has been 00222546.8 patent disclosure, this patented technology has solved thickness and the adeciduate problem of hardened layer that guarantees hardened layer preferably, therefore also can guarantee the hardness and the service time of needs, but this technology is to be made of the method that is bumped into cover in overcoat, therefore it is many to exist manufacturing procedure, expend the energy and material is many, and cause the high problem of cost, simultaneously, though the cylinder sleeve overcoat after the wearing and tearing is intact, but, therefore can not change interior cover because interior cover is difficult to separate with overcoat.
The objective of the invention is to solve in the prior art, the cementation zone thickness of electroplating can not be satisfied the demand, the caducous defective of the hardened layer of surfacing, with the material of different performance under the state of fusion, merge with action of centrifugal force, invent a kind of production technology and cylinder sleeve of drilling pump of composite element.
The present invention be achieved in that make have different mechanical performances two kinds of materials under molten condition in rotary die first a kind of material of casting member, after reaching designing requirement, the another kind of materials with different properties of casting before not solidifying, at this moment, because a kind of material of preceding a kind of material and back all is in the state of fusion, so two kinds of materials will have a fused layer; Continue a kind of material in casting back,, continue rotary die, member is solidified fully, then member is carried out remaining processing up to reaching design thickness.
Advantage of the present invention is: in casting cycle, because two kinds of materials all are to cast under the state of fusion, so the fused layer of a transition is arranged between two kinds of materials, in conjunction with very firm, can not occur coming off; When composite bed after the use of long period wearing and tearing, member can also be melted down and be warmed to molten condition, the composite material of casting one deck required thickness can use again after the processing.
Fig. 1 is the structure cut-away view according to the cylinder sleeve of drilling pump of the present invention's casting.
Below in conjunction with accompanying drawing, with the cylinder sleeve of drilling pump is that example provides embodiments of the invention: a kind of production technology of composite element and cylinder sleeve of drilling pump comprise a kind of production technology of composite element and the cylinder sleeve of drilling pump of making according to a kind of production technology of composite element; Make have different mechanical performances two kinds of materials under molten condition in rotary die first a kind of material of casting member, after reaching design size, the material of the another kind of different performance of casting before not solidifying, retaining member continues rotation after reaching design thickness, just takes out member after member solidifies fully; A kind of production technology of composite element can be used for casting earlier to the member outer surface have hardness require, to the workpiece of the no hardness requirement in component inside surface, can be used for casting earlier to the member outer surface do not have hardness require, to the workpiece that the component inside surface has hardness to require, also can be used to cast has the workpiece of different hardness requirement to inside and outside surface of member; Cylinder sleeve of drilling pump according to production technology manufacturing of the present invention comprises cylinder sleeve of drilling pump basic material layer 4 and rigid composite material layer 1, elder generation's casting basic material layer 4 in rotary die, the cylindrical of basic material layer 4 has shoulder 3, shoulder 3 can be arranged on the top of basic material layer 4, can be arranged on the middle part or the bottom of basic material layer 4, also can not have shoulder; When basic material layer 4 reaches design thickness, continue rotary die, casting hard composite bed 1 when basic material 4 still is in high temperature and molten condition, reach design thickness after, retaining member continues rotation, solidifies fully up to member, carries out other operations then; Because rigid composite material layer 1 carries out under high temperature and molten condition with the casting of basic material layer 4, therefore, a mixing together layer 2 is arranged between rigid composite material layer 1 and the basic material layer 4, and after solidifying, rigid composite material layer 1 merges with the faying face of basic material layer 4; When casting hard composite bed 1, can add acid-proof or etch-proof alloy material as required, like this, the member that machines just can reach acid-proof or etch-proof technical purpose; Production technology of the present invention can be used for the processing and forming of the material members of two or more different mechanical performances.
Claims (3)
1. the production technology of a composite element, it is characterized in that: make have different mechanical performances material under molten condition in rotary die first a kind of material of casting member, the material of the another kind of different performance of casting before not solidifying, continue rotary die, retaining member continues rotation and solidifies the back taking-up fully up to member.
2. a cylinder sleeve of drilling pump of making according to the production technology of claim 1 is made of cylinder sleeve of drilling pump basic material layer and hard composite bed, it is characterized in that: a fused layer is arranged between described basic material layer and the rigid composite material layer.
