Description
Technical field
The utility model relates to well logging field of engineering technology, especially a kind of hydraulic core machine of splitting is with compound knife plate.
Background technique
In order to be understood more intuitively and grasp earth formation in drilling process, it is often necessary to which rotary-cut takes out whole section from stratum
Core, core needs to carry out various Physico-chemical tests work after going out well, needs the direction cutting perpendicularly by core from vertical face.Core
There is greater hardness, incision is highly difficult, so cutting by the way of hydraulic lifting knife plate, traditional knife plate uses common No. 45
Steel plate is material, milled out the edge of a knife in side, is made by quenching stiffened processing, applies at the scene, the edge of a knife it is durable
Property it is excessively poor, be mainly shown as passivation, abrasion, the edge of a knife fades away into radiussed, to lose the incision ability to core, one
As cut hundred pieces of core lazy weight with regard to carrying out repairing knife processing work, so service efficiency is poor, the maintenance frequency is more, to now
It splits core work and causes biggish problem in field.
Summary of the invention
The nonabradable hydraulic core machine of splitting of one kind is provided utility model aims to solve above-mentioned technical problem to use
Compound knife plate.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:
One kind is hydraulic to split the compound knife plate of core machine, including knife rest and alloy blade, and the knife rest top is formed with blade peace
Tankage, lower part be formed with installation interface with split core machine structural member and quickly connect installation, alloy blade lower part tight fit is pacified
In blade installation slot, which is formed with the edge of a knife, and the edge of a knife upper center is formed with edge of a knife high point, the knife
Extend on mouth from edge of a knife high point to two sides and be symmetrically formed there are two the blade bevel edge that is arranged diagonally downward, and two blade bevel edges it
Between be formed with bevel edge angle α.
Preferably, the bevel edge angle α is 170 °.
Preferably, the blade angle β of the edge of a knife is 30 °.
The beneficial effects of the utility model are: traditional knife plate is due to using common No. 45 steel, hardness is lower, usually exists
When low permeability formation coring, core operation is split in progress less than hundred times, and the edge of a knife on knife plate is just declared to scrap, and carries out repairing knife
Or it just can be carried out operation after tool changing processing.The utility model is using new material, the alloy combination knife plate of new construction, in cutting hard
When core, the edge of a knife is in a kind of nondestructive state, and scene was not suffered a loss using 1 year or more edge of a knife toughness, due to special nose angle
Degree, core cuts speed, efficiency is accelerated, and live work efficiency is promoted larger.
Detailed description of the invention
Fig. 1, which is that the utility model is hydraulic, splits the core machine structural schematic diagram of compound knife plate.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments:
Referring to Fig. 1, the hydraulic compound knife plate of core machine of splitting of the utility model includes knife rest 1 and alloy blade 3, the knife rest
1 is made of No. 45 steel, and 1 top of knife rest is formed with blade installation slot 2, lower part be formed with installation interface 7 with split core machine
Structural member quickly connects installation, and the 3 lower part tight fit of alloy blade is mounted in blade installation slot 2,3 top of alloy blade
It is formed with the edge of a knife 5,5 upper center of the edge of a knife is formed with edge of a knife high point 6, the extension pair from edge of a knife high point 6 to two sides on the edge of a knife 5
Claim the blade bevel edge being arranged diagonally downward there are two being formed, and is formed with bevel edge angle α between two blade bevel edges.
Preferably, the bevel edge angle α is 170 °.
Preferably, the blade angle β of the edge of a knife 5 is 30 °.
The utility model devise it is a kind of it is novel it is hydraulic split the compound knife plate of core machine, using the rigid blade of special alloy and 45
The composite construction of number ordinary steel knife rest forms, and alloy blade 3 is designed to a kind of special geometry, there is a sharp knife
Mouthful, blade angle and geometry appearance are formed by special designing, have sharp, anti-roll characteristic, while will not be in big pressure
The problem of crushing knife, breaking occur under effect.Design has blade installation slot 2 on knife rest 1, and alloy blade 3 can be quickly installed on
Among mounting groove, the design of 1 lower part of knife rest has installation interface 7, can quickly with split core machine structural member and connect installation.Cutting operation
When, cut quality is good, and long working realizes the long-time service of knife plate without state of wear.
Knife rest 1 is that the installation carrier of alloy blade 3, blade installation slot 2 and alloy blade 3 are installed for tight fit, alloy knife
Piece 3 is fastened on knife rest 1, and jacking strength is transferred to knife rest 1 by installation interface 7 by hydraulic jack, disperses force to by
Edge of a knife high point 6 is simultaneously dispersed on the edge of a knife 5 toward two sides, and strength is transmitted on core by the edge of a knife 5, forms slitting force, from
And realize the quick incision operation of core, edge of a knife high point 6 has simultaneously positions anti-roll function to core.
In conclusion the content of the utility model is not limited in the above embodiments, those skilled in the art can
To propose other embodiments within the technological guidance's thought of the utility model, but to be included in this practical new for these embodiments
Within the scope of type.
