Description
Technical field
The invention belongs to cutter and its manufacturing process area, specifically, be related to a kind of ultra-thin alloy cutting knife of overlength and its
Manufacture method.
Background technology
Alloy cutting knife is widely used in cutting for the articles such as wooden, plastics；For example a kind of photo frame cutting knife, its are shaped as growing flat
Shape, from 500mm to 2500mm, thickness is typically in below 10mm for length；Common alloy cutting knife length is in below 2000mm, thick
In more than 10mm, less, prior art disclosure satisfy that the performance requirement of the alloy cutting knife to its processing and manufacturing difficulty to degree；But, by
Requirement is cut in handicraft product, cutting precision is higher, the length to alloy cutting knife and thickness requirement are also increasingly harsher, and length exists
More than 2000mm, thickness are more and more in the ultra-thin alloy cutting knife application of overlength of below 10mm, however, the manufacture work of this cutting knife
Skill still can not then meet its performance requirement using traditional processing method, and so as to cause to cut, precision is low, and service life is low
Varied problem.
Analysis conventional technique is processed the ultra-thin alloy cutting knife produced problem of above-mentioned overlength and is understood, the essence of long flat alloy cutting knife
Degree is embodied in its overall linearity, and it is 0.03-0.05mm that traditional handicraft is processed the linearity that common alloy cutting knife can reach,
And the linearity that the ultra-thin alloy cutting knife of overlength that traditional handicraft is processed can reach have dropped an order of magnitude, be only capable of maintaining
0.1mm or so, this obviously greatly reduce the precision quality of alloy cutting knife；In addition, common alloy cutting knife is direct using ratio-frequency welding
Alloy cutter head is welded with cutter hub, is converted to the ultra-thin alloy cutting knife of above-mentioned overlength, cause alloy cutter head not prison welding solid, rear
Easily it is partially disengaged during continuous straightening technique, has a strong impact on quality and the service life of alloy blade.
Content of the invention
1st, problem to be solved
The problem for cutting requirement of high accuracy kerf quality product can not be met for existing cutting knife, and the present invention provides a kind of

On Copper Foil, then the weld seam welding between cutter hub and blade is carried out with ratio-frequency welding；
Step 5, heat treatment, the product after welding in step S4 is directly placed in 200-250 DEG C of baking oven, is incubated 3-4
After hour, taking-up is cooled to 60-70 DEG C carries out next step；
Step 6, secondary coarse adjustment are straight；
Step 7, roughing, will be straight for secondary coarse adjustment in step 6 after product carry out respectively six faces of profile milling processing,
Wherein per one face of milling and the face is detected and straightening simultaneously, until product linearity is to 0.03mm；
Step 8, fine grinding, equal to the disposable milling of product to alloy cutter head, cutter head thickness first, then to product straightening,
It is 0.02mm linearity to be obtained by detection on marble test desk；
Step 9, opens inclined edge, forms the edge of a knife in the common end grinding inclined edge of cutter hub and blade；
Step 10, accurate adjustment are straight, product is placed on marble test desk and observes sags and crests, after mark, using screw body
Salient point correction is carried out, completes accurate adjustment straight.
Preferably, in step 6, the straight concrete grammar of secondary coarse adjustment is to be placed on greatly the product after step 5 first
Sags and crests observed by reason stone test desk, after mark, are positioned on forcing press, by point driving switch by product coarse straightening to linearity are
Within 1mm.
Preferably, the concrete grammar for carrying out salient point correction using screw mechanism in step 10 is, after marking sags and crests
Workpiece be placed on marble test desk, the support for being provided with screwed hole is fixed on marble test desk, and makes screw thread

A kind of ultra-thin alloy cutting knife of overlength, is manufactured using said method.
3rd, beneficial effect
Compared to prior art, beneficial effects of the present invention are：
(1) cutting knife of the present invention has higher sharpness as its thickness is little, length big with respect to prior art, because
This disclosure satisfy that the quality requirement that cuts of requirements at the higher level, improves and cuts efficiency；
(2) common welding is compared in method of the present invention welding step, and silver foil serves adhesion effect, but due to blade
Flexural deformation during straightening and roughing, silver foil are easily separated with cutter head collision, are reduced product quality, are therefore increased
Copper Foil, serves buffering silver foil and the effect of cutter head, thereby increases yield strength and pliability after increasing Copper Foil；Existing welding
Also have using Copper Foil welding, but light is high with Copper Foil welding requirements welding temperature, alloy cutter head is easily damaged, and its adhesive is not
By force；
(3) method of the present invention by coarse adjustment is straight, secondary coarse adjustment is straight, accurate adjustment directly make each step of manufacturing process can be strict
Meet linearity requirement, so as to reduce error accumulation, improve the quality of production of finished product cutting knife；In the present invention, accurate adjustment directly adopts screw mandrel
Mechanism carries out salient point correction and has higher degree of regulation, can avoid the offset error of forcing press and manual synchronizing, can control
Salient point corrected area processed, does not produce secondary injury；
(4) cutting knife manufactured using the inventive method has longer service life, main body while quality is really up to the mark
Now blade firm welding, be difficult to peel off, be unlikely to deform.
