Description
Technical field
The present invention relates to a kind of milling trains for being used in particular for rolling the green bodies such as kitchen knife.
Background technology
Kitchen knife is common daily necessities, needs first to make green body when producing kitchen knife.The mode of production cutter blank is main at present
There are two types of：The first, is ground out the inclined-plane of cutter blank by the way of grinding on plank.It second, is individually rolled using milling train
Go out cutter blank, as illustrated in fig. 1 and 2, the roll 4 of milling train is cylindrical structure, circumferentially opens that there are one rollings in the periphery of roll 4
The length and kitchen knife length of groove 4a, rolling groove 4a are roughly the same, and the depth of rolling groove 4a gradually increases.Roll cutter blank
When, plank moves between the roll and support roller of milling train, the rotation rolling cutter blank of roll 4, and from the knife spine of kitchen knife to point of a knife side
To roll forming, single cutter blank is obtained by smoothing after rolling 4-5 times back and forth.
The defect of existing roll is：1, a cutter blank can only be once rolled, efficiency is very low；2, roll when plank from knife spine to
Point of a knife direction extends, and since resistance is gradually reduced, can finally form unwanted overlap at point of a knife, it is both time-consuming to cut the overlap
Material is wasted again, and the consistency of cutter blank is poor, is unfavorable for subsequent grinding everything goes well with your work to carry out.
Invention content
Technical problem to be solved by the present invention lies in a kind of milling train is provided, rolling efficiency to be improved reduces waste of material,
And improve the consistency of cutter blank.
Technical scheme is as follows：A kind of milling train, it is characterised in that：Including rack (1) and roll (4), wherein machine
Being rotatably assorted by the first support device (2) on frame (1) has support roller (3), and described roll is correspondingly provided with right over the support roller (3)
Roller (4), the roll (4) are mounted on by the second support device (5) in rack (1)；The roll (4) is cylindrical structure, should
The periphery of roll is made of two symmetrical circular conical surfaces (4a '), the two circular conical surfaces intersect at the middle part of roll (4), and roll
The broad in the middle of roller (4), both ends are small, and the roll (4) of rotation can be with the upper face of rolled plate；
Spacing between the support roller (3) and roll (4) can adjust, the support roller (3) and opposite turn of roll (4)
It is dynamic, molding is rolled by roll (4) when plank is by gap between support roller (3) and roll (4).
When plank continues through gap between this case roll and support roller, roll (4) rolled plate upper plate of rotation
Face, and will roll deep in the middle part of plank, forward and backward side is rolled than shallower, and is in shallow " V " font, and in the operation of rolling material from
The middle part of plank forward, rear side extend, material is thus formed two sections of symmetrically arranged continuous cutter blanks, this two sections continuous cutter blanks are connected in
Together, intermediate position is point of a knife part, and forward and backward side is knife spine part.Also, since the thickness of knife spine part is larger, therefore resistance
It is larger, it thus can effectively avoid generating overlap, and then effectively reduce waste of material.In following process, by punching press by two
Duan Lianxu cutter blanks separate, then by blanking by every section of continuous cutter blank blanking at a individual cutter blanks of n, need not be smoothed after blanking,
The consistency of cutter blank is good, is thus convenient for the sanding operation of subsequent mechanical.
Using above technical scheme, the principle and conventional mill of this mill milling cutter blank are entirely different, can not only continuously roll
System greatly improves the efficiency of rolling cutter blank, effectively reduces waste of material, and can reliably ensure the consistency of cutter blank, be conducive to
Follow-up intelligent machineization polishing is smoothed out, and effectively overcomes that conventional mill efficiency is low, waste of material is big and cutter blank consistency is poor
Defect, may be not only suitable for rolling cutter blank, but also the similar green body of rolling other structures can be promoted the use, and originally roll
Machine is simple in structure, is easy to manufacture and use.
As preferred design, the both ends of the roll (4) are respectively equipped with an installation axle (6), this two installation axles (6) with
Roll (4) is integrally formed, and the axial line of the axial line of two installation axles (6) and roll (4) is on same straight line, and is installed
Axis (6) is rotatably assorted with second support device (5) respectively.
As a kind of embodiment of this case, the circular conical surface (4a ') is single circular conical surface.
As another embodiment of this case, the circular conical surface (4a ') is combination circular conical surface, and by the first circular conical surface
(4a ' -1) and the second circular conical surface (4a ' -2) are formed by connecting, and the taper of the second circular conical surface (4a ' -2) is more than the first circular conical surface
(4a ' -1) taper, and the second circular conical surface (4a ' -2) is located at the end of roll ontology (1).
Using the above structure, the green body knife spine rolled out is especially thick, reduces from knife spine toward point of a knife direction thickness especially fast.
In the present case, the roll (4) and support roller (3) number are one, and the height of support roller (3) is unable to adjust,
And the height of roll (4) can adjust.
In the present case, one group of charging support roller (7) is equipped on the left of the support roller (3) side by side, the support roller (3) right side is simultaneously
Row be equipped with one group of discharging support roller (8), these charging support rollers (7) and discharge support roller (8) be loose roll, and with the branch
Roller (3) is supportted in same level.
Using the above structure, charging can be assisted by feeding support roller (7), and is assisted out by the support roller (8) that discharges
Material.Also, it is loose roll to feed support roller (7) and discharging support roller (8), and the reason of design in this way is the charging support of active
Roller (7) and the bad speeds match with roll of discharging support roller (8) rotating speed, thus this case using manually or mechanically hand push movable plate material into
Material or discharging.
In order to take into account structural strength and convenient material drawing well, the material of the roll (4) and installation axle (6) is carbon steel.
Advantageous effect：This milling train can not only continuous rolling go out billet, greatly improve the efficiency of rolling cutter blank, and from centre
It is rolled toward both sides, not only shut out two billets simultaneously, but also material is made to extend from intermediate toward both sides, to effectively reduce waste of material,
The consistency that can also reliably ensure cutter blank is conducive to being smoothed out for subsequent mechanicalization polishing, and is conducive to be further ensured that production
Quality；The operation principle and conventional mill of this milling train are entirely different, effectively overcome that conventional mill efficiency is low, waste of material is big and
The defect of cutter blank consistency difference may be not only suitable for rolling cutter blank, but also it is similar to promote the use rolling other structures
Green body, and this rolling mill structure is simple, is easy to manufacture and use.
