Abstract
The invention discloses a die for pressing a connector of an oil drill rod. The die comprises an upper die part, a lower die part and a punch part. The upper die part comprises an upper die seat, an upper die base plate, an upper die core and an upper die head which are connected through an upper clamping plate, wherein a die groove is formed in the upper die head. The lower die part comprises a lower die seat, a lower die base plate, a lower die core and a lower die head which are connected through a lower clamping plate, wherein a die groove is formed in the lower die head. The punch part comprises two groups of punch components, wherein each group of the punch components are formed by connecting a punch base, a punch middle connecting body and a punch fixedly and sequentially. According to the invention, the automatic production of the connector of the oil drill rod is realized through the die driven by a hydraulic machine, so that the production efficiency is improved greatly. In addition, the die has the advantages of simple structure and low cost.
Description
Technical field
The invention belongs to hydraulic press mould technical field of forging, particularly relate to a kind of mould of suppressing joint of petroleum drill rod.
Background technology
Development along with society, continuing to increase of automobile pollution, all the more the fierceness of international energy contention, the contention of petroleum-based energy is very important, corresponding oil exploitation development technique is constantly brought forth new ideas, in oil exploitation, need to beat very dark well, the length of single drilling rod is limited, needing to use tool joint couples together two sections drilling rods, but this joint will have sufficient intensity and hardness, otherwise the so dark place in the down-hole, if there is problem, changing is very complex 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, joint of petroleum drill rod in the past mostly is integrated machine processing or the rear machined of simple forging, production technology falls behind, and production efficiency is low, and various performance deficiencies are more, can not satisfy the demand for development in epoch far away, it is high therefore to design a kind of working (machining) efficiency, it is particularly important that the mould of the joint of petroleum drill rod that cost is low seems.
Summary of the invention
Goal of the invention of the present invention is: for the characteristics of joint of petroleum drill rod, propose the mould of the compacting joint of petroleum drill rod that a kind of working (machining) efficiency is high, cost is low.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of mould of suppressing joint of petroleum drill rod comprises: part of the upper die, part of the lower die and drift part; Wherein:
Described part of the upper die is comprised of upper bolster, upper baffle plate, upper mold core and upper die head; Connect by upper clamp between described upper bolster, upper baffle plate, upper mold core and the upper die head; Described upper die head is provided with the mould groove;
Described part of the lower die is comprised of die shoe, lower baffle plate, lower mold core and lower die head; Connect by lower clamp between described die shoe, lower baffle plate, lower mold core and the lower die head; Described lower die head is provided with the mould groove;
Described drift part is comprised of two groups of punch-head assemblies, and every group of punch-head assembly is comprised of the drift base that is fixedly connected sequentially, drift intermediate connector and drift.
As preferred version, the present invention has also adopted following technical scheme:
Described part of the upper die is identical with the part of the lower die.
Described two groups of punch-head assemblies are identical.
Advantage and good effect that the present invention has are:
1. the present invention according to the characteristics of joint of petroleum drill rod, utilizes the hydraulic press driven mold to realize the automated production of joint of petroleum drill rod by adopting technique scheme, has greatly improved production efficiency.
2. the part of the upper die among the present invention is identical with the part of the lower die, adopts symmetric design, and the drift part also adopts symmetric design, therefore have simple in structure, the advantage that cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1, upper bolster; 2, upper baffle plate; 3, upper mold core; 4, upper clamp; 5, upper die head; 6, drift base; 7, drift intermediate connector; 8, drift; 9, lower die head; 10, lower mold core; 11, lower baffle plate; 12, die shoe; 13, lower clamp.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of mould of suppressing joint of petroleum drill rod comprises: part of the upper die, part of the lower die and drift part; The part of the upper die is comprised of upper bolster 1, upper baffle plate 2, upper mold core 3 and upper die head 5; Connect by upper clamp 4 between upper bolster 1, upper baffle plate 2, upper mold core 3 and the upper die head 5; Be provided with the mould groove at upper die head 5; The part of the lower die is comprised of die shoe 12, lower baffle plate 11, lower mold core 10 and lower die head 9; Connect by lower clamp 13 between die shoe 12, lower baffle plate 11, lower mold core 10 and the lower die head 9; Lower die head 9 is provided with the mould groove; The drift part is comprised of two groups of punch-head assemblies, and every group of punch-head assembly is comprised of the drift base 6 that is fixedly connected sequentially, drift intermediate connector 7 and drift 8.In this specific embodiment, be symmetrical structure between part of the upper die and part of the lower die, two groups of punch-head assemblies, so the part of the upper die is identical with the part of the lower die, two groups of punch-head assemblies are also identical.
The course of work of the present invention is: utilize manipulator that the first blank of joint of petroleum drill rod is delivered in the mould of hydraulic press, utilize the mould groove on upper die head 5 and the lower die head 9 that blank is blocked, hydraulic machine slide block down drives the part of the upper die and moves down, and fits through upper die head 5 and lower die head 9 complete closed, finish the up and down extrusion modling of workpiece, drift 8 left and right sides extrusion billets of both sides, through the pressurize in 5 seconds, the slide block backhaul is to upward position, 8 backhauls of left and right sides drift, joint of petroleum drill rod is finished compressing.
More than record, only for utilizing the embodiment of this origination techniques content, modification, variation that any the technology person of being familiar with uses this creation to do all belong to the claim that this creation is advocated, and are not limited to those disclosed embodiments.
