At present, existing tool joint processing is more is using one forging scheme of a mould, main step：Blanking-add
Heat-base-die forging-punching-forging post processing-roughing-heat treatment.There are complex process, processing for this forging method
The shortcomings that efficiency is low and of high cost.
Utility model content
The purpose of this utility model is to provide a kind of first mould two pieces forging mold of drilling rod connecting, it can simplify drilling rod connecting
The forging technology of head, has the characteristics that high in machining efficiency and reduces processing cost, to solve the first mould of drilling rod connecting in the prior art
The above problem present in one forging process.
For this purpose, the utility model uses following technical scheme：
A kind of first mould two pieces forging mold of drilling rod connecting, it includes upper die and lower die, the first upsetting punch and the second upsetting punching
Head, the lower die are located at the underface of the upper mold, and the first upsetting punch and the second upsetting punch are to that should be able to move horizontally
Ground is arranged at the both sides of the lower die, wherein, the upper mold includes upper mold seat, Upper Die-sleeve and upper mold core, under the lower die includes
Die holder, lower die-sleeve and lower mold core, are correspondingly arranged on shaping boss in the middle part of the upper mold core and lower mold core, and the upper mold core and
Lower mold core is provided with the forming cavity for coordinating tool joint shape to set in the both sides of the shaping boss.
Especially, the first upsetting punch and the second upsetting punch may be contained within corresponding punch holder, the punch
Seat is connected with drive cylinder.
The beneficial effects of the utility model are that the first mould two pieces forging mold of the drilling rod connecting can compared with prior art
A mould two is carried out to suitable tool joint to forge, and not only simplify the forging technology of tool joint；And processing efficiency is improved,
Reduce processing cost.
Brief description of the drawings
Fig. 1 is the structural representation for the first mould two pieces forging mold of drilling rod connecting that the utility model embodiment 1 provides
Figure.
Embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, Fig. 1 is the first mould two pieces forging of drilling rod connecting that the utility model embodiment 1 provides
The structure diagram of mould.
In the present embodiment, a kind of first mould two pieces forging mold of drilling rod connecting includes upper die and lower die, 1 and of the first upsetting punch
Second upsetting punch 2, the lower die are located at the underface of the upper mold, and the upper mold includes upper mold seat 3, Upper Die-sleeve 4 and upper mold
Core 5, the lower die include die holder 6, lower die-sleeve 7 and lower mold core 8, and the Upper Die-sleeve 4 is fixed on the lower section of the upper mold seat 3,
The upper mold core 5 is fixed on the Upper Die-sleeve 4, and the lower die-sleeve 7 is fixed on the top of the die holder 6, the lower mold core 8
It is fixed on the lower die-sleeve 7, the middle part of the upper mold core 5 and lower mold core 8 is correspondingly arranged on shaping boss 9, and the upper mold
Core 5 and lower mold core 6 are provided with the forming cavity 10 for coordinating tool joint shape to set in the both sides of the shaping boss 9.Pass through into
Type boss 9 and forming cavity 10 form the overall profile of tool joint.And by being molded segmentation of the formation of boss 9 for later stage sawing
Line.
The first upsetting punch 1 and the second upsetting punch 2 are correspondingly arranged in the both sides of the lower die, and first upsetting
Forging 1 and second upsetting punch 2 of punch may be contained within punch holder 11, and the punch holder 11 is all connected with drive cylinder, the driving
The first upsetting of hydraulic oil cylinder driving punch 1 and the second upsetting punch 2 do expanding-contracting action in the horizontal direction.
The above-mentioned first specific forging method of mould two pieces forging mold of drilling rod connecting is, by taking NC50 tool joints as an example, it is wrapped
Include following steps：
1) bar of appropriate length is heated, if the length of bar is L1, the length of tool joint finished product is L2, then
L1 ﹥ 2L2, while heating-up temperature is 1160 ± 20 DEG C, Frequency Induction Heating pitch time 90S~120S；
2) bar heated is put into lower mold core；
3) upper mold downlink molds, and the first upsetting punch and the advance of the second upsetting punch carry out upsetting, at the center of bar
Form cut-off rule；Wherein 1160 ± 20 DEG C of initial forging temperature, 850 DEG C~1050 DEG C of final forging temperature, first, second upsetting punch of both ends
Advance at the same time, extrude upsetting connector, during finish-forging the extruding of bar center produce left and right two pieces connector gross weight, stroke cut-off rule；
4) forging post processing, in particular to a heat treatment of reduction stress and removal endoporus gross weight, heat treatment process are：
Using 800 DEG C~1000 DEG C of normalizing or annealing of waste heat after forging, and with stove natural cooling.
5) sawing is carried out along the cut-off rule, forms two tool joints；
6) roughing and heat treatment being carried out to tool joint, roughing refers to rough carry out one-time mechanical processing,
The defects of possible, unnecessary surplus, the heat treatment easy to follow-up flaw detection and material are removed, heat treatment uses modifier treatment, quenches
Fire+high tempering, i.e., using 880 DEG C of water quenchings, then 650 DEG C of tempering, when the time is 2 small.
Above example is to elaborate the basic principle and characteristic of the utility model, and the utility model is from above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes, these changes
Change and change and both fall within claimed the scope of the utility model.The utility model requires protection scope will by appended right
Ask book and its equivalent thereof.
