Abstract
The invention discloses an automatic polishing technology of a forged knife, which comprises the following steps of: first selecting a forging molding knife blank with a tapered cross section and putting for later use after thermal processing and the end surface grinding of the knife blank; modifying a cloth roller 1 and a sisal hemp polishing cloth roller 2 for later use and then carrying out mechanical polishing on the knife blank by the cloth roller 1 and the hemp polishing cloth roller 2 which are modified. The forged knife is mechanically processed instead of original manual production, the polished knife body is as bright as a mirror, the grade of the forged knife is improved, the product quality is stable, the defective rate is reduced, the production efficiency is greatly improved, and the concept that the forged knife cannot be mechanically polished by a polishing machine is broken.
Description
Technical field
The invention belongs to the processing glossing of cutter, specifically, relating to a kind of is the technology that raw material carry out the mechanization polishing to forge cutter blank.
Background technology
The cutter blank that is used for the processing kitchen knife is divided into two kinds, a kind of is that steel board punching press shearing forms, another kind is the cutter blank that forms through forging, the cutter blank thickness unanimity that forms is sheared in the steel board punching press, the surfacing polishing can utilize common polishing machine to polish, the efficient height can large-scale batch production, appearance looks elegant, constant product quality; Through forging the cutter blank that forms, to organize more evenly by the carbide that forges the back metal material, crystal grain is thinner, the more refinement that distributes, hardness height, good toughness, wearability, resistance to impact is better, liked by the consumer.But the cutter blank that process forges is with respect to the cutter blank of sheet material, and cross section has tapering, and thickness is inconsistent, and its cutter middle part is recessed cambered surface, can not carry out the mechanization polishing with polishing machine.At present, forging the cutter glossing all is artificial polishing, hold cutter blank sand polishing one by one earlier, stamping antiscuffing paste with sisal hemp at last polishes once more and finishes, not only inefficiency in the artificial bruting process, and the outward appearance after the polishing often do not have punching press to shear the cutter blank that forms, and it is like that attractive in appearance as minute surface to utilize polishing machine to polish out, always seem that class is very low, is not more and more accepted by market.
Summary of the invention
The object of the present invention is to provide a kind of be applicable to the mechanization automatic polishing technology that forges cutter forge cutter automatic polishing technology.
For achieving the above object, technical scheme of the present invention is as follows:
A, earlier choose cross section be taper forge the moulding cutter blank, stand-by after the grinding of Overheating Treatment, cutter blank end face; Organize more even by the carbide of the metal material after forging, crystal grain is thinner, more refinement distributes, hardness height, good toughness, wearability, resistance to impact is better, but the cutter blank that process forges is with respect to the cutter blank of sheet material, its middle part is recessed cambered surface and uneven, can not carry out the mechanization polishing with the light water grinding machine.Also can only manually polish, has only the levigator of adjustment emery wheel angle, the seamed edge that the grinding of cutter blank end face utilizes levigator abrasive wheel end face and emery wheel excircle to form is polished to the recessed cambered surface of cutter hub lateral middle, utilizes the levigator abrasive wheel end face that the knife back and cutting edge are polished again.
B, will be on the polishing machine the columniform cloth rewinder roll of usefulness be installed, be processed as a cloth rewinder roll that is connected to form by awl section head and the tail, apply glue on cloth rewinder roll then, the diamond dust that evenly is stained with granularity respectively and is 45#～240# different size is stand-by;
C, the cylindrical sisal hemp polishing cloth rewinder roll of usefulness will be on the polishing machine be installed, it is stand-by to be processed as the sisal hemp polishing cloth rewinder roll that is connected to form by awl section head and the tail equally;
D, in the stand-by cloth rewinder roll of step B, select the cloth rewinder roll more than granularity 4 couple from coarse to fine, successively the stand-by cutter blank of steps A is polished by order from coarse to fine, during installation, each is installed cloth rewinder roll is corresponding up and down, form the machining gap that the narrow end of an end broadens gradually in twos between the Dui Ying awl section, during polishing, the stand-by vertically corresponding insertion of cutter blank of steps A is gone up lower cloth roller and is fixed in the machining gap between the section of awl in twos, the narrow end of cutter blank is positioned at the narrow end of machining gap, the wide end of cutter blank is positioned at the wide end of machining gap, and cloth rewinder roll rotates its polishing;
High-grade more as required gift cutter and so on can polish several times, and the diamond dust of selecting is thinner more.
Changed and forged traditional processing mode and the idea that cutter can only manually be polished, to forge the cutter outward appearance and promote a class, make and forge the industry that cutter also can enter high-grade cutter, and the mechanization polishing makes product quality more stable, improved production efficiency greatly, artificial in the past polishing was polished 50 at most in one day, can polish 800 in present one day.
E, cutter blank are after the cloth rewinder roll polishing, sisal hemp being polished cloth rewinder roll changes the outfit on the polishing machine again, stamp antiscuffing paste on sisal hemp polishing cloth rewinder roll surface, sisal hemp polishing cloth rewinder roll is fixed in the machining gap between the section of awl in twos about vertical corresponding insertion of cutter blank, the narrow end of cutter blank is positioned at the narrow end of machining gap, the wide end of cutter blank is positioned at the wide end of machining gap, the cutter hub after the rotation of sisal hemp polishing cloth rewinder roll obtains polishing to its polishing.
The seamed edge that the grinding of above-mentioned cutter blank end face utilizes levigator abrasive wheel end face and emery wheel excircle to form is polished to the recessed cambered surface of cutter hub lateral middle, utilizes the levigator abrasive wheel end face that the knife back and cutting edge are polished.
In earlier stage the grinding of mechanization is also taked in the grinding of cutter blank, has improved the mechanization degree that forges the whole processing technology of cutter.
Beneficial effect: the manual production that the present invention forges before the cutter has become Mechanized Processing, cutter hub outward appearance after the polishing is as minute surface, promoted the class that forges cutter, product quality is more stable, percent defective reduces, and improved production efficiency greatly, also broken forge cutter can not be with the idea of polishing machine mechanization polishing.
