Description

A kind of blanking mold of joint of petroleum drill rod
Technical field
The present invention relates to oil drill rocker technical field, particularly relate to a kind of blanking mold of joint of petroleum drill rod.
Background technology
Petroleum industry is the pillar industry of China, and along with the development of society and being growing more intense of international competition, corresponding oil exploitation development technique is constantly brought forth new ideas, simultaneously also more and more stricter to the requirement of winning apparatus.
Need to beat very dark well in the process of oil exploitation, the limited length of single drill pipe, need with tool joint, two sections of drilling rods to be coupled together, and this joint will have enough intensity and hardness, otherwise the place so dark in down-hole, if there is problem, changing gets up is quite complicated and loaded down with trivial details, so the demand of the joint of petroleum drill rod of this high strength and high hardness also just increases thereupon.At present, in the process of joint of petroleum drill rod, carrying out jumping-up process to circular bar is one of important process of base, the blanking mold of traditional joint of petroleum drill rod comprises drift and base, manipulator is utilized to be placed on base by bar-shaped blank, then drift is utilized to carry out forward extrusion process to one end of bar-shaped blank, after one end completes, drift reclaims, utilize manipulator that bar-shaped blank is carried out 180 degree to turn around, then backward extrusion process is carried out to other one end of bar-shaped blank, found by practice, there is following defect in the base process of drift: one, inefficiency, two, the percent defective of processing is high.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of blanking mold with the joint of petroleum drill rod that operating efficiency is high, percent defective is low.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
A blanking mold for joint of petroleum drill rod, comprising:
For clamping drift and the part of the upper die of upsetting under driving blank;
For clamping the part of the lower die of blank;
And the discharging part for blank is ejected from part of the lower die;
Wherein: described part of the upper die comprises the drift base for clamping drift, the upper bolster be fixedly connected with described drift base and the driving oil cylinder for driving upper bolster to move up and down; Described part of the lower die comprises counterdie base, is fixed on the lower mould bottom plate of described counterdie base upper surface, is fixed on the lower die-sleeve of described lower mould bottom plate upper surface, in described lower die-sleeve, is provided with lower die head; Described discharging part comprises the lower knockout rod for driving described lower die head to move up and down and the driving oil cylinder for driving lower knockout rod to move up and down; Described counterdie base and lower mould bottom plate are provided with the through hole passed through for lower knockout rod, and described lower knockout rod is fixedly connected with described lower die head.
Preferably, the present invention additionally uses following technical scheme:
The lower mold core for coordinating blank caliber size is provided with at the inwall of described lower die-sleeve.
Stop collar is provided with between the first half and lower mold core of described lower die-sleeve inwall.
Knockout rod cover is provided with at the top edge of described lower mould bottom plate through hole.
Described drift is provided with groove, described lower die head is provided with projection.
The advantage that the present invention has and good effect are: by adopting technique scheme, the blanking mold in the present invention can carry out jumping-up process from the two ends of bar-shaped blank simultaneously, therefore drastically increases operating efficiency; Simultaneously owing to being carry out jumping-up from the two ends of bar-shaped blank simultaneously, be provided with the lower mold core for coordinating blank caliber size at the inwall at lower die-sleeve simultaneously; Therefore drastically increase the crudy of product, reduce percent defective; Because the present invention is provided with the discharging part for being ejected from part of the lower die by blank, therefore after upset forging process completes can very convenient, quickly by blank take out, further increase operating efficiency; Because the present invention is provided with knockout rod cover at the top edge of lower mould bottom plate through hole, lower die head therefore can be protected well not damaged.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, upper bolster; 2, nurse is locked; 3, drift base; 4, drift; 5, lower die-sleeve; 6, counterdie base; 7, lower knockout rod; 8, knockout rod cover; 9, lower mould bottom plate; 10, lower die head; 11, lower mold core; 12, stop collar.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of blanking mold of joint of petroleum drill rod, comprising:
For clamping the part of the upper die of drift 4 upsetting under driving blank; Described part of the upper die comprises drift base 3 for clamping drift 4, with described drift base 3 by the upper bolster 1 locking nurse 2 and be fixedly connected with and the driving oil cylinder for driving upper bolster 1 to move up and down;
For clamping the part of the lower die of blank; Described part of the lower die comprises counterdie base 6, is fixed on the lower mould bottom plate 9 of described counterdie base 6 upper surface, is fixed on the lower die-sleeve 5 of described lower mould bottom plate 9 upper surface, in described lower die-sleeve 5, is provided with lower die head 10;
And the discharging part for blank is ejected from part of the lower die; Described discharging part comprises the lower knockout rod 7 for driving described lower die head 10 to move up and down and the driving oil cylinder for driving lower knockout rod 7 to move up and down; Counterdie base 6 and lower mould bottom plate 9 are provided with the through hole passed through for lower knockout rod 7, and lower knockout rod 7 is fixedly connected with between lower die head 10.
In real work, because the caliber size of bar-shaped blank is often not quite similar, therefore as preferred specific embodiment, be provided with the lower mold core 11 for coordinating blank caliber size at the inwall of lower die-sleeve 5.In actual upset process, lower mold core 11 can prevent from colliding between drift and lower die-sleeve 5, also can play certain protective effect to drift 4.
In upsetting process, move upward in process to prevent drift 4 and skid off lower mold core 11, between the first half and lower mold core 11 of lower die-sleeve 5 inwall, be provided with stop collar 12.
Overlap in 8 and lower die head 10 folding process to prevent knockout rod and collide with lower mould bottom plate 9, be provided with knockout rod cover 8 at the top edge of lower mould bottom plate 9 through hole.
Meanwhile, in order to realize quick upsetting process, drift 4 is provided with groove, lower die head 10 is provided with projection.
Operation principle of the present invention is: utilize manipulator to be placed in lower mold core 11 by bar-shaped blank, then drive hydraulic oil cylinder driving drift 4 move downward thus process the upper surface of bar-shaped blank, drive hydraulic oil cylinder driving lower die head 10 to make it process the lower surface of bar-shaped blank simultaneously; So just achieve the upset forging process to bar-shaped blank; After upset forging process completes, drive hydraulic oil cylinder driving drift 4 to move upward, moving upward with rear drive hydraulic oil cylinder driving lower die head 10 ejects blank from lower mold core 11; Utilize manipulator to be taken away by blank, this completes the upset forging process of a blank.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
