Abstract
The invention discloses a wet sanding process for a forged stainless steel knife using an abrasive tape, which includes the steps: firstly, selecting a forged stainless steel knife blank with conical cross section, and subjecting the stainless steel knife blank to thermal treatment; and secondly, fixing an abrasive tape disk and the stainless steel knife blank to a water mill, using the end face of the abrasive tape disk to grind two surfaces of the stainless steel knife blank respectively, grinding each surface of the knife blank from one end to the other during grinding, and using a nozzle of the water mill to spray water to cool the knife blank so that the temperature of the knife blank is not more than 200 DEG C, wherein the abrasive tape disk is composed of abrasive tapes radially disposed on a wheel disc. By the process, chromium oxide on middle arc concaves and uneven surfaces of the stainless steel knife blank can be removed effectively, total weight of material before forging is reduced, cost of forging the stainless steel knife is reduced, and production efficiency is improved.
Description
Technical field
The invention belongs to cutter processing technology field, be specifically related to a kind of grinding process of forging non-corrodible steel 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 stainless steel materials punching press shearing forms, and another kind is the stainless steel cutter blank that forms through forging.It is consistent that the cutter blank thickness that forms is sheared in the stainless steel materials punching press; Can carry out levigator mechanization in the surfacing grinding process once roughly grinds with a fine grinding and accomplishes; The efficient height can large-scale batch production, appearance looks elegant, constant product quality, but be difficult for mill.Through forging the stainless steel cutter blank that forms, to organize more evenly through the carbide that forges the back metal material, crystal grain is thinner, the more refinement that distributes, hardness is high, good toughness, wearability, resistance to impact is better, liked by the consumer.But through the cutter blank that the forges cutter blank with respect to sheet material, its cutter middle part has tapering, thickness inconsistent for recessed cambered surface, cross section.
Traditional grinding technique for forging non-corrodible steel knife all is that artificial grinding is to remove the chromium oxide on stainless steel cutter blank surface; At first emery wheel is slightly polished; The people holds cutter blank and on the emery wheel that rotates, slowly grinds; With diamond dust cutter blank is finish grinded repeated multiple times again, last polishing cloth adds that antiscuffing paste polishes, and technology is loaded down with trivial details, efficient is very low, workman's amount of labour is big; And whole forging non-corrodible steel cutter blank is in artificial bruting process; In the emery wheel corase grind stage owing to be water spray cooling of artificial polishing, the bad control of cutter hub temperature, surpass 400 degree when the temperature of cutter blank because with the emery wheel friction after; Will cause the decrease of hardness of cutter blank, scrap is many.
Announced a kind of " grinding technique for forging non-corrodible steel knife " by name on the China national intellectual property board web; The patent No. is ZL200810069557.5; This process reform the grinding of forging non-corrodible steel cutter blank all the time all can only rely on the present situation of hand grinding; Former manual production has been become Mechanized Processing, and production efficiency has obtained improving greatly.But; Because three parts that this processing method need differ to thickness on the cutter hub: the knife back, middle recessed cambered surface and blade, roughly grind respectively and finish grind, being divided into for six steps carries out; And middle recessed cambered surface also will carry out different special process and carry out grinding, and its procedure of processing is more; Main is: as shown in Figure 1, wheel grinding must be with recessed cambered surface 1 complete resection in the middle of the whole cutter blank, and solid line is the profile before the grinding, and dotted line is the profile after the grinding.Suppose that the cutter blank gross weight before the grinding is 5.2 liang, the stainless steel knife total amount after the grinding reduces to 4.8 liang, and waste of material is big, and manufacturing cost is than higher; In addition, owing to stock removal is determined by recessed cambered surface, and the gross weight that how much directly influences the finished product cutter of stock removal, so defect rate is higher relatively.
Summary of the invention
Order of the present invention provides a kind of stainless steel knife grinding process; Can effectively remove the chromium oxide on recessed arc in forging non-corrodible steel cutter blank middle part and rough surface; With the raw material gross weight of minimizing before forging, reduce forging non-corrodible steel knife manufacturing cost, enhance productivity.
For this reason, the technical scheme that the present invention adopted is: a kind of forging non-corrodible steel knife sand ribbon watermill process is characterized in that: comprise the steps:
Be preferably, the sheet sand ribbon on the dish of said sand ribbon is fixed by welding on the annular wheel disc.
The present invention can produce less deflection when contacting when having utilized the sand ribbon with the stainless steel cutter blank dexterously; The sand ribbon can be reached in the recessed cambered surface to the cutter blank middle part; Effective grinding is carried out on whole cutter blank surface (comprising in the recessed cambered surface), thus remove that cutter blank forms in the process of forging chromium oxide.The beneficial effect that has is:
(1) only needs a grinding to accomplish, improved production efficiency;
(2) when the recessed cambered surface at grinding cutter blank middle part, along the surfacing of recessed cambered surface, can be with whole recessed cambered surface complete resection, stock removal is little, and waste of material is few, and the material that the finished product cutter of same weight uses has still less been practiced thrift cost widely;
(3) because stock removal is few, guarantee the gross weight of finished product cutter effectively, reduced defect rate.
Description of drawings
The forward and backward profile sketch map of the grinding technique for forging non-corrodible steel knife grinding of introducing in Fig. 1 background technology.
Fig. 2 is the structural representation of the sandbag dish that uses among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
A kind of forging non-corrodible steel knife sand ribbon watermill process comprises the steps:
Claims (2)
1. a forging non-corrodible steel knife sand ribbon watermill process is characterized in that: comprise the steps:
Step 1, select for use cross section to forge tapered stainless steel cutter blank, the stainless steel cutter blank is heat-treated;
Step 2, sand ribbon dish and stainless steel cutter blank are fixed on the levigator; End face (A) with the sand ribbon dish carries out grinding respectively to two surfaces of stainless steel cutter blank; End from the cutter blank surface during grinding is ground to the other end; Make the cutter blank temperature be no more than 200 ℃ with the cooling of levigator nozzle water spray simultaneously, said sand ribbon dish is made up of the sheet sand ribbon (2) on the annular wheel disc (1) that is the emitting shape layout.
2. according to the described forging non-corrodible steel knife of claim 1 sand ribbon watermill process, it is characterized in that: the sheet sand ribbon (2) on the dish of said sand ribbon is fixed by welding on the annular wheel disc (1).
