Abstract
The whole coupling head of hollow rod is the connection to existing hollow rod body, adopts " monomer coupling head " improvement of the technology that links after welding.Novel process is to be processed into left and right coupling head at the two ends of the hollow rod direct jumping-up of local heat; Make coupling head become as a whole with hollow rod; One-shot forming must not welded, and makes connection more firm, simplifies technology, reduces cost.
Description
Existing hollow rod coupling method is made up of left end coupling head, sealing ring, right-hand member coupling head three parts; Its left and right two ends coupling head is to adopt 35 chrome molybdenum steel, is processed into＜the monomer coupling head through forging 〉, be welded into the technology of one then with hollow rod.This technology weak point is: the technology more complicated, and the weld bond place is difficult to ensure the quality of products, and fastness is relatively poor, and wastes the problem of metal material in addition.
The purpose of this new technology is: it is the connecting process of an integral body that a kind of coupling head and hollow rod of making is provided.
The technical measures of this new technology are: the two ends of hollow rod body, pass through local heat, through mould, hydraulic means, the directly thick moulding of pier, be processed into the coupling head of left and right two ends then, make the two ends coupling head become as a whole with hollow rod, must not weld, one-shot forming improves the connection quality, strengthens to connect fastness, simplify technology, have popularizing value.
Fig. 1 is the thick moulding figure of the left and right two ends coupling head of hollow rod pier
Fig. 2 is a hollow rod connection part bitmap.1 is the left end coupling head among Fig. 2, the 2nd, and right-hand member coupling head, the 3rd, sealing ring.
Fig. 3 is that the hollow rod two ends connect the thick shaped device schematic diagram of pier
1 is hydraulic means among Fig. 3, the 2nd, and bearing support, the 3rd, mould, the 4th, fixing support, the 5th, heater, the 6th, device plane.
Claims (2)
1, the thick moulding process of oil oil pick-up tube coupling head pier.Be slightly to become coupling head at the direct pier in body two ends, it is characterized in that: coupling head becomes as a whole with body, no longer with forging the technology that the welding of coupling head and body links.
2, by the thick moulding process of the described oil oil pick-up tube of claim 1 coupling head pier, it is characterized in that: the left and right coupling head of the thick one-tenth of body two ends local heat pier.
