Abstract
The invention discloses a grind shoe manufacture method which comprises the steps as follows: a grind shoe body is manufactured by carbon steel or tungsten carbide; a surfacing layer on the grind shoe body is arranged at a downward welding position; a workpiece is preheated by flame firstly; then a welding tool is mounted to clamp the grind shoe body; austenite stainless steel or copper alloy is selected as the material of the surface of the welding tooling contacted with the grind shoe body and the surfacing layer; YD hard alloy welding rods are used for implementing resurfacing welding on the grind shoe body; after the welding is completed, an inner blocker is loosened to take off the welding tool. According to the grind shoe manufacture method, the welding is convenient, and the resurfacing welding forming is good; and the grind shoe become a finished product without secondary processing after the welding is completed.
Description
Technical field
The present invention relates to the preparation method of oil exploitation underground work workpiece, specifically a kind of manufacture method of the junk mill for the down-hole grinding.
Background technology
Junk mill belongs to a kind of workover tool, body and carbide alloy section, consists of, and the carbide alloy section is welded on bodies top, has advantages of that grinding efficiency is high.The method of making has following two kinds: a kind of is just to reserve the body of one section tubbiness when the junk mill body is made, external mold as pile-up welding hard alloy, this section external mold has just connected together with the alloy of built-up welding after welding is completed, and the effect when junk mill uses has just descended greatly like this; Another kind method is to add a frock in order to built-up welding in the junk mill periphery after the junk mill body is completed, and removes frock with cutting working method again after welding is completed, and has so not only bothered but also uneconomical.
Summary of the invention
The junk mill manufacture method that the purpose of this invention is to provide a kind of handling ease.
Technical scheme of the present invention is as follows:
A kind of junk mill manufacture method, comprise the steps:
Make the junk mill body with carbon steel or tungsten carbide;
make the junk mill bodies top be in downhand position, at first use flame preheat junk mill body, then load onto welding tooling and clamp the junk mill body, and it is identical with the outer side clearance of junk mill bodies top to regulate the built-up welding contact layer that makes the frock inboard, this welding tooling comprises and is enclosed within this external frock body of junk mill, have in the frock body for the interior card that clamps the junk mill body, interior cartoon crosses screw rod and nut is arranged on the frock body, the holding screw of regulating the welding tooling position also is installed on the frock body, welding tooling is austenitic stainless steel or copper alloy with the material of the face that the junk mill body contacts with overlay cladding,
Carry out built-up welding with YD type carbide electrode on the junk mill body, unclamp interior card after welding is completed, take off welding tooling and get final product.
The invention has the beneficial effects as follows: because the welding of YD type hard alloy composite material surfacing welding belongs to gas brazing, the tyre body alloy of this welding rod has good wellability to carbon steel and tungsten carbide particle at a certain temperature, tyre body alloy is poor to the wellability of austenitic stainless steel at same temperature, and is poor to the wellability of copper alloy.Therefore, utilize this difference, the material that the material of choose reasonable junk mill body and frock contact with overlay cladding, make alloy welding deposit and junk mill body firm welding can not connect together with frock again, convenient welding, built-up welding are shaped, after built-up welding is completed, frock is unclamped to take off get final product, be finished product after junk mill is soldered and need not secondary operations, improved the junk mill working (machining) efficiency, reduced production cost.
Description of drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 be the embodiment of the present invention in weld deposit process, the installation diagram of junk mill body and welding tooling.
Fig. 2 is the schematic diagram of the welding tooling that uses of the present invention.
The specific embodiment
Specific embodiments of the invention 1, a kind of junk mill manufacture method, comprise the steps:
One, material is prepared:
1, use steel alloy 35C
RM
OOr tungsten carbide is made junk mill body 9;
2, prepare welding tooling, this frock comprises can be enclosed within the outer frock body 2 of junk mill body 9, and frock body 2 consists of jointly three block parts, and forms a ring-type integral body.Have in the frock body of trisection for card 3 and wild card 4 in 3 (or a plurality of) clamping junk mill body 9, interior card 3 is used for chucking junk mill body, in this example wild card 4 be mainly used in three block parts connect do as a whole, and as the positioning datum of interior card 3; Interior card 3 and wild card 4 are arranged on frock body 2 by screw rod 6 and nut 5, and the holding screw 1 of regulating the welding tooling position also is installed on frock body 2, and the material of the built-up welding contact layer 7 of frock body inboard is austenitic stainless steel;
Two, welding:
As shown in Figure 1, the first step, be horizontal junk mill body 9 tops; Second step, be preheated to 600 ℃ of left and right with flame to junk mill body 9 tops, is used for obtaining better built-up welding effect, and produces excessive stress while avoiding installing additional the laggard windrow weldering of frock; The 3rd step was placed in frock on junk mill body 9, with holding screw 1, frock was fixed on junk mill body 9, and regulated holding screw 1 and make the built-up welding contact layer 7 of frock inboard identical with junk mill body 9 top outer gaps, and the thin and thick of assurance overlay cladding is even; In the 4th step, carry out built-up welding with YD type hard alloy composite material surfacing welding on the junk mill body; The 5th step, after completing, welding unclamps interior card, take off welding tooling.Complete welding.
Tool structure in above-described embodiment as shown in Figure 2, frock body 2 use carbon steels are made, built-up welding contact layer 7 is＞the austenitic stainless steel overlay cladding of 5mm, after built-up welding is completed, car evenly is cut into trisection along axis 12 with body with wire cutting method after completing after given size, boring, tapping are completed, and with interior card 3, wild card 4, screw rod 6 and nut 5, the body of trisection is combined into round frock body 2.Can regulate the position of interior card 3 by the cooperation of screw rod 6 and nut 5, interior card 3 use austenitic stainless steels are made.Also have holding screw 1 on frock body 2, be used for adjusting the relative position of frock body 2 and junk mill body 9.
