Abstract
The invention discloses a kind of New-type operating blade processing technology, it is related to medical instruments field, the knife blade processing technology manufactures knife blade by the way of heating quenching in medium temperature salt bath furnace again lonneal, knife blade any surface finish, without pit, no soft spots, hardness can reach 750HV.Tested through production practices for many years, the heating quenching in the medium temperature salt bath furnace newly prepared, knife blade steady quality.Support chip can play a part of supporting operative incision when zero, easy to use, flexible.
Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of New-type operating blade processing technology.
Background technology
Knife blade is the medicine equipment commonly used in surgical operation, and knife blade and knife handle are used cooperatively.Scalpel
Piece is disposable, and handle of a knife is not.Other operating theater instruments are nor in each use gone out by high pressure disposably
Bacterium.
Existing knife blade uses stainless steel making mostly.But traditional knife blade processing technology very simple,
Processed using the heat treatment method of simple quenching plus lonneal, cause the hardness of knife blade not uniform enough, quality is very not
It is stable.Traditional scalpel structure is simple, is merely capable of for cutting, and can not play Auxiliary support effect.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of New-type operating blade processing technology, in the knife of blade body
The support chip of strip is designed at the back side, and support chip is vertical with blade body, and support chip can play a part of supporting operative incision.
To achieve the above object, the present invention provides following technical scheme：A kind of New-type operating blade processing technology, it is special
Sign is：The New-type operating blade includes blade body, and mounting hole and blade, the knife of blade body are machined with blade body
The support chip of strip is provided with the back of the body, support chip is vertical with blade body, and support chip at blade tip with not contacting, the new-type hand
Art blade processing technology is as follows：
(1) use Cr12 cold-rolled steels to forge blade body of the thickness for 0.45mm, and processed by bending mould
Support chip；
(2) suitable fixture is selected, is loaded knife blade by technological requirement, is preheated in 450~500 DEG C of air furnace,
Preheating time is 10~15h；
(3) knife blade is placed and 860~890 DEG C of quenchings will be heated in salt bath furnace, and 50~55%NaCl+50 of use~
45%Na2CO3Solution is as salt bath medium, using sodium ferrocyanide [Na4Fe(CN)6] or hardwood charcol deoxidation, 3~6h of insulation it
Oil cooling is to room temperature afterwards；
(4) knife blade after quenching is reheated to 220~260 DEG C of tempering, air cools down after being incubated 2~5h
To room temperature.
Preferably, the thickness of the support chip is 0.45mm, and the width of support chip is 8~38mm.
Beneficial effect using above technical scheme is：The knife blade processing technology, which uses to heat in medium temperature salt bath furnace, quenches
The mode of fire lonneal again manufactures knife blade, knife blade any surface finish, no pit, no soft spots, and hardness can reach
750HV.Tested through production practices for many years, the heating quenching in the medium temperature salt bath furnace newly prepared, knife blade steady quality.Branch
Blade can play a part of supporting operative incision when zero, easy to use, flexible.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the front view of New-type operating blade of the present invention；
Fig. 2 is the side view of New-type operating blade of the present invention.
Wherein, 1- blade bodies, 2- mounting holes, 3- support chips, 4- blades.
Embodiment
A kind of preferred embodiment of New-type operating blade processing technology that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 and Fig. 2 shows a kind of embodiment of New-type operating blade processing technology of the present invention：The New-type operating knife
Piece includes blade body 1, and mounting hole 3 and blade 4 are machined with blade body 1, strip is provided with the knife back of blade body 1
Support chip 2, support chip 2 is vertical with blade body 1, and support chip 2 at the tip of blade 4 with not contacting.The thickness of support chip 2 is
0.45mm, the width of support chip 2 is 8~38mm.
The New-type operating blade processing technology is as follows：
(1) use Cr12 cold-rolled steels to forge blade body 1 of the thickness for 0.45mm, and processed by bending mould
Support chip；
(2) suitable fixture is selected, is loaded knife blade by technological requirement, is preheated in 450~500 DEG C of air furnace,
Preheating time is 10~15h；
(3) knife blade is placed and 860~890 DEG C of quenchings will be heated in salt bath furnace, and 50~55%NaCl+50 of use~
45%Na2CO3Solution is as salt bath medium, using sodium ferrocyanide [Na4Fe(CN)6] or hardwood charcol deoxidation, 3~6h of insulation it
Oil cooling is to room temperature afterwards；
(4) knife blade after quenching is reheated to 220~260 DEG C of tempering, air cools down after being incubated 2~5h
To room temperature.
The knife blade processing technology manufactures scalpel by the way of heating quenching in medium temperature salt bath furnace again lonneal
Piece, knife blade any surface finish, no pit, no soft spots, hardness can reach 750HV.Test through production practices for many years, match somebody with somebody newly
Heating quenching in the medium temperature salt bath furnace of system, knife blade steady quality.Support chip 2 supports the work of operative incision when can play zero
With easy to use, flexible.
The above is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
Without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.
