Abstract
The present invention relates to a kind of preparation methods with opening slotting cutter, manufacturing process includes: that the outer circle of metal disk is uniformly cut into several unidirectional sawteeth grooves into cutter hub, its main feature is that: after the trench bottom of serrated slot is uniformly (1) produced plurality of openings slot along one face centerline direction of cutter hub, quench oil, tempering are carried out to cutter hub；(2) weld an alloy cutter head in the same direction in each serrated slot of cutter hub, form milling cutter；(3) by step, (2) manufactured milling cutter carries out vacuum drying oven heat treatment.The present invention produces open slot in cutter hub on one side, cutter hub internal stress is released when cutting, eliminate trembling for cutter hub, it solves the problems, such as to tremble when milling cutter work, reduce processing resistance, the abrasion that reduces blade, resonance, swaging clamp and the phenomenon of forging a knife generated when milling cutter being prevented to work, not only improve the machining accuracy and cutting speed of product, but also caused by being greatly reduced because of product rejection rate raw material waste.
Description
Technical field
The invention belongs to metal material cutting tool technical fields, more particularly to a kind of preparation with opening slotting cutter
Method.
Background technique
In metal material cutting field, cutting-tool engineering and Machining Technology for Cutting means are all around cutter efficient low-consume
The continuous exploration practice of this target and development and perfection.Cutting of the metal material cutting tool in actual cut process
Ability and effect directly affect the qualification rate of the quality and product that process product.
Currently known metal saw disposably completes the materials workpiece such as non-ferrous metal, red copper or stainless steel
When machining, either progress climb cutting processing or upmilling processing, cutter is during the cutting process by the shadow of cutting resistance
It rings, while cutting edge shape and workpiece surface profile agree with degree deficiency, make cutter hub unbalance stress at cutting point, lead to cutter hub
Processing resistance caused by generation is trembled, edge wear, processing resonance, swaging clamp and the phenomenon that forge a knife, not only affect product
Machining accuracy, reduce cutting speed, and increase the rejection rate of product, cause the waste of raw material.
Summary of the invention
The present invention is to solve technical problem present in well-known technique and provide the machining accuracy height of the product of production, production
High-efficient, long service life, product rejection rate is low, reduces the waste of raw material, and a kind of band of product processing cost is greatly reduced
There is the preparation method of opening slotting cutter.
The technical scheme adopted by the invention is that:
A kind of preparation method with opening slotting cutter, manufacturing process includes: that metal disk is made in metal material, will be golden
The outer circle for belonging to disk is uniformly cut into several unidirectional sawteeth grooves into cutter hub, and cutter hub is 42CrMo material, feature
It is: further includes making step:
(1) described to open by the trench bottom of serrated slot along 120 degree of one face centerline direction of cutter hub uniformly distributed three open slots of scraping
Mouth slot is circle hook open slot, and the bill direction of the round hook open slot and the direction of serrated slot slot point are same direction, right
Cutter hub two sides carries out preliminary grinding；The open slot gradually narrows from the width from the bill end direction of trench bottom to the circle hook of serrated slot；
It is HRC32-368 by cutter hub hardness quenching and tempering using 860 DEG C of oil of quenching, then with 390 degree of temperings；Cutter hub two sides is carried out again
Fine grinding；
(2) the omnipotent welding rod of MG130 is used, welds a YT class alloy in the same direction in each serrated slot of cutter hub
Cutter head forms milling cutter；
(3) by step, (2) manufactured milling cutter carries out vacuum drying oven heat treatment, completes the manufacturing process with opening slotting cutter.
The advantages and positive effects of the present invention are:
1, the present invention is formed with using the cutter hub one side on metal saw along the trench bottom of serrated slot along centerline direction
The open slot of cloth, milling cutter is provided with small elastic deformation when cutting, release cutter hub because cutting unbalance stress generate in answer
Power eliminates trembling for cutter hub so that cutter has anti-shudder working ability, solve metal saw processing tremble ask
Topic reduces processing resistance, the abrasion that reduces blade, the resonance generated when cutter being prevented to work, swaging clamp and forges a knife existing
As not only increasing the machining accuracy and cutting speed of product, and raw material caused by being greatly reduced because of product rejection rate
Waste.
2, the present invention is had higher using having the 42Cr2Mo steel of superhigh intensity and toughness as cutter hub after modifier treatment
Fatigue limit and anti-repeat impact ability, Low temperature impact toughness is good, the creep strength and creep rupture strength of high temperature Shi Yougao, into one
Step improves the machining accuracy of cutter, extends cutting-tool's used life.
3, by that will justify being evenly arranged on cutter hub of hook open slot trisection, shock resistance and deep trouth etc add the present invention
Work efficiency fruit especially highlights, and manufactured Product Precision and processing efficiency are greatly improved.
4, cutter head is welded to cutter hub using welding good fluidity, the omnipotent welding rod of MG130 easy to operate, that intensity is high by the present invention
On, cutter head falls off from cutter hub when effectively preventing cutter work, further improves cutting-tool's used life.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram with opening slotting cutter that the present invention makes；
Fig. 2 is the enlarged drawing in Fig. 1 at A.
In figure: 1- cutter hub, 2- open slot, 3- alloy cutter head, 4- serrated slot, 5- blade.
Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows:
A kind of preparation method with opening slotting cutter, manufacturing process includes: that metal disk is made in metal material, in gold
The outer circle for belonging to disk is uniformly cut into several unidirectional sawteeth grooves into cutter hub, its main feature is that: further include making step:
(1) after the trench bottom of serrated slot uniformly being produced plurality of openings slot along one face centerline direction of cutter hub, to cutter hub into
The capable oil, tempering quenched；
(2) weld an alloy cutter head in the same direction in each serrated slot of cutter hub, form milling cutter；
(3) by step, (2) manufactured milling cutter carries out vacuum drying oven heat treatment, completes production of the present invention with the slotting cutter that is open
