Abstract
A kind of new stirring-head modified for tool steel mixing yoghurt, it includes mixing needle (1), it is characterized in that the outer surface of the mixing needle (1) is threaded (2), the center of mixing needle (1) is equipped with inner cavity (3), it is equipped in inner cavity (3) head tree (4), helical blade (5) is installed on head tree (4).The present invention can preferably implementation tool steel surface layer modification, the stirring header structure of designed manufacture is simple, manufactures convenient for actual production, and it is preferable to be modified quality, is suitble to industrial production application.
Description
Technical field
The present invention relates to a kind of material modification technology, especially a kind of tool steel agitating friction modification technology, specifically
It is a kind of new stirring-head modified for tool steel mixing yoghurt.
Background technique
It is well known that tool steel is as in cutter use process, it may appear that phenomena such as abrasion, service life is shorter, is
Raising tool steel cutter life, the invention patent mainly pass through mixing yoghurt Technology design and have manufactured a stirring
Head is for being modified tool steel surface layer.This method is simple, but effect is preferable.
Summary of the invention
The purpose of the present invention is will appear abrasion in use for existing tool steel cutter, the longevity is used
Shorter problem is ordered, a kind of new stirring modified for tool steel mixing yoghurt that agitating friction modification technology uses is designed
Head.
The technical scheme is that
A kind of new stirring-head modified for tool steel mixing yoghurt, it includes mixing needle 1, it is characterized in that the stirring
The outer surface of needle 1 is threaded 2, and the center of mixing needle 1 is equipped with inner cavity 3, is equipped with head tree 4 in inner cavity 3, on head tree 4
Helical blade 5 is installed.
The head tree 4 can move up and down in inner cavity 3, and moving distance is no more than 1mm, when mixing needle 1 revolves counterclockwise
When turning, head tree 4 then drives helical blade 5 to rotate clockwise, and to guarantee modification area metal plastic flowing, obtains optimal change
Property layer.
The screw pitch of the screw thread 2 is depending on material, hard material coarse thread, soft material closely-pitched.
The quantity of the helical blade 5 is determined according to the length of head tree 4.
Beneficial effects of the present invention:
The present invention can preferably implementation tool steel surface layer modification, the stirring header structure of designed manufacture is simple, convenient for practical raw
Manufacture is produced, modification quality is preferable, is suitble to industrial production application.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of new stirring-head modified for tool steel mixing yoghurt, it includes mixing needle 1, the mixing needle 1
Outer surface be threaded 2, the screw pitch of screw thread 2 is depending on material, hard material coarse thread, soft material closely-pitched.Stirring
The center of needle 1 is equipped with inner cavity 3, is equipped with head tree 4 in inner cavity 3, helical blade 5 is equipped on head tree 4, helical blade 5
Quantity is determined according to the length of head tree 4.The head tree 4 can (such as gear rotating mechanism, piston drive in conventional drive mechanism
Motivation structure, electric pushrod, hydraulic cylinder, cylinder etc.) driving under move up and down in inner cavity 3, moving distance be no more than 1mm,
When mixing needle 1 rotates counterclockwise, head tree 4 then drives helical blade 5 to rotate clockwise, to guarantee modification area plastic deformation
Flowing, obtains optimal modified layer.
For the present invention by manufacturing and designing the modified stirring-head of a suitable tool steel surface, essence is exactly to pass through stirring-head
External screw-thread stirs surrounding metal counterclockwise, while being rotated clockwise by the internal head tree with helical blade, will stir
Nearby plasticized metal stirs into rapidly semi-molten state to head, convenient for forming the modified layer needed.This stirring header structure is simple, production
It is easily manufactured, it is easy to promote and utilize, and can guarantee modified quality.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
