Abstract
The utility model relates to the field of forming dies, in particular to a split-type oil drill pipe joint forming die. The split-type oil drill pipe joint forming die comprises an upper die and a lower die, and is characterized in that the upper die comprises a die sleeve, five movable blocks which are connected in sequence are fixed in the die sleeve and serve as a guide sleeve, a welding diameter forming sleeve, a major diameter forming sleeve, an external cone forming sleeve and a guide sleeve in sequence, and the lower die has the same structure with the upper die. The split-type oil drill pipe joint forming die can be assembled and disassembled more flexibly due to the split-type structure; for different models of products, corresponding movable blocks can be reused if partial sizes are the same, and accordingly materials and working hours can be saved; compared with a traditional integrated die, the size of a single movable block of the split-type oil drill pipe joint forming die is greatly reduced, and precision can be conveniently improved through the wire-electrode cutting process and other processes.
Description
Technical field
The utility model relates to a kind of mould, specifically a kind of split type joint of petroleum drill rod mould.
Background technology
The manufacturing process of joint of petroleum drill rod is generally such: the bar of first preparing a section, then utilize intermediate frequency furnace to heat it, through vertical press, go out preformed joint blank again, again through horizontal press and mould, what after mould upper and lower mould matched moulds, go out is exactly the joint blank of moulding, finally by crossing some processing processing, forms joint of petroleum drill rod.
In the manufacture process of joint of petroleum drill rod, mould is a very important link, and the quality of its quality directly has influence on the performance of joint.Traditional Design of Dies be take the shaping dies of whole joint conventionally as main, exists larger drawback.As long as finished size is required to have trickle change at every turn, all need redesign and manufacture whole mould, waste time and energy; Because unitary mould size is larger, comparatively difficulty is installed also simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of split type joint of petroleum drill rod mould, can overcome the defect of traditional integrally forming mould, improves the flexibility of mould handling.
In order to solve the problems of the technologies described above, the technical scheme adopting is: a kind of split type joint of petroleum drill rod mould, comprise upper die and lower die, it is characterized in that, patrix comprises a die sleeve, in die sleeve, be fixed with five loose pieces that connect successively, be followed successively by fairlead, weldering footpath molding sleeve, large footpath molding sleeve, outer cone molding sleeve and fairlead; Counterdie has the structure identical with patrix.
Preferred: the side of five above-mentioned loose pieces is processed with several screws, and available screw and die sleeve are fixed.
The beneficial effects of the utility model are: split-type structural of the present utility model, makes the handling of mould more flexible; If five loose pieces are installed into die sleeve and have any problem, only need process corresponding loose piece on mould; If the product portion size of different size is identical, can, by corresponding loose piece recycling, save material and man-hour; Compare traditional unitary mould, the size of the single loose piece of this Split type die reduces greatly, is convenient to adopt the techniques such as line cutting to improve precision.
Accompanying drawing explanation
Fig. 1, structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
As shown in Figure 1, for structure chart of the present utility model, a kind of split type joint of petroleum drill rod mould, this mould comprises patrix 1 and counterdie 2, patrix 1 comprises a die sleeve 3, in die sleeve 3, be fixed with five loose pieces that connect successively, five loose pieces are respectively fairlead 4, weldering footpath molding sleeve 5, large footpath molding sleeve 6, outer cone molding sleeve 7 and fairlead 8; Counterdie 2 also has the structure identical with patrix 1, and counterdie 2 also comprises a die sleeve 3, is fixed with five loose pieces that connect successively in die sleeve 3, and five loose pieces are followed successively by fairlead 4, weldering footpath molding sleeve 5, large footpath molding sleeve 6, outer cone molding sleeve 7 and fairlead 8.
The specific embodiment: coordinate the pre-profiling mould of a series of manufacture joint of petroleum drill rod to introduce the present embodiment mould of the present utility model.In the present embodiment, the side of fairlead 4, weldering footpath molding sleeve 5, large footpath molding sleeve 6, outer cone molding sleeve 7 and fairlead 8 is equipped with screw hole 9, passes screw hole 9 fixing with die sleeve 3 by screw.
First prepare a section bar, then bar is heated, bar after heating is gone out to preformed joint blank through vertical press again, again through horizontal press, finally by mould, what after fairlead 4, weldering footpath molding sleeve 5, large footpath molding sleeve 6, outer cone molding sleeve 7 and fairlead 8 matched moulds of split in mould upper and lower mould, go out is exactly the drill stem connector blank of moulding, the joint of petroleum drill rod of standard has completed 80%, carries out some processing process the tool joint that forms complete standard finally by the drift of crossing patrix 1 and counterdie 2 left and right.
