Abstract
The invention discloses a magnetic automatic abrasive belt grinding process for forging knife blanks. The process includes the steps of 1, heating a stainless steel knife blank with the cross section forged in the conical shape; 2, producing a special magnetic automatic abrasive belt grinder; 3, starting a conveyor belt mechanism and an abrasive belt grinding mechanism in the magnetic automatic abrasive belt grinder to grind the surface of the stainless steel knife blank, and spraying cool water to keep the temperature of the knife blank to be lower than 200 DEG C through a nozzle. The process has the advantages that oxide skin on the surface of the forged stainless steel knife blank can be removed effectively, procedures are few and the process is energy saving, environmentally friendly and highly automated.
Description
Technical field
The invention belongs to the tool sharpening technology field, be specifically related to a kind of sbrasive belt grinding technique 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 the stainless steel materials shearing forms, and another kind is the stainless steel cutter blank that forms through forging.The cutter blank thickness that the stainless steel materials shearing forms is consistent, can large-scale batch production, but with rear difficult mill.Through forging the stainless steel cutter blank that forms, to organize more evenly by the carbide that forges rear 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.
Traditional grinding technique for forging non-corrodible steel knife is all that artificial grinding is to remove the oxidation shell on stainless steel cutter blank surface, at first emery wheel is slightly polished, the people holds cutter blank and slowly grinds on the emery wheel that rotates, cutter blank is refined repeated multiple times with diamond dust again, last polishing cloth adds that antiscuffing paste carries out polishing, and technique is loaded down with trivial details, efficiency is very low, workman's amount of labour is large.
Announced a kind of " grinding technique for forging non-corrodible steel knife " by name on 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 greatly improving.The subject matter that this processing method exists is: procedure of processing is more, the operation relative complex; Need the power of 30kw left and right to drive the levigator rotation, power consumption is large; During levigator polishing simultaneously, dust is large, very not environmental protection.
Summary of the invention
Order of the present invention is to provide a kind of cutter blank magnetic automatic abrasive belt grinding process that forges, and can effectively remove the oxidation shell on forging non-corrodible steel cutter blank surface, and the while manufacturing procedure is few, energy-conserving and environment-protective, and automaticity is high.
For this reason, the technical solution adopted in the present invention is: a kind of cutter blank magnetic automatic abrasive belt grinding process that forges comprises the steps:
Step 1, select cross section to forge tapered stainless steel cutter blank, and the stainless steel cutter blank is heat-treated rear stand-by;
At first, unload the belt on conveyer mechanism (2), repack abrasive band into, simultaneously the abrasive band of sbrasive belt grinding mechanism (3) is unloaded, rotate again handwheel (5), after tilting to by screw-nut body (6) drive conveyer mechanism (2) angle that needs, start conveyer mechanism (2), by the abrasive band on conveyer mechanism (2), the driven pulley of sbrasive belt grinding mechanism (3) is ground to rubber tire with tapering;
Then, backward rotation handwheel (5), drive conveyer mechanism (2) by screw-nut body (6) and get back to level, unload the abrasive band on belt mechanism (2), load onto corresponding belt, simultaneously the abrasive band of sbrasive belt grinding mechanism (3) is loaded onto, at this moment, the axis of the driven wheel of the driven wheel of conveyer mechanism (2) and sbrasive belt grinding mechanism (3) is parallel to each other, and the space between the abrasive band in the belt on conveyer mechanism (2) and sbrasive belt grinding mechanism (3) can guarantee that the tapered forging non-corrodible steel cutter blank of cross section passes through;
Be preferably, totally four groups, the described sbrasive belt grinding mechanism (3) in step 2, front and back are disposed on the top of conveyer mechanism (2).By the acting in conjunction of many groups sbrasive belt grinding mechanism, a grinding of stainless steel cutter blank is put in place.
Further, the described magnetic automatic abrasive belt milling drum in step 2, also comprise collecting tank (8), sends into nozzle (7) by pipeline after cooling water is collected and recycle, with saving water resource.
Antiskid groove (A) on described sbrasive belt grinding mechanism (3) driven pulley in step 2 twist, be convenient to processing, and skidproof effect is better.
Beneficial effect of the present invention:
(1) pass through the magnetic automatic abrasive belt milling drum of design specialized, realized the automatic grinding of forging non-corrodible steel cutter blank, simultaneously, before processing, change the outfit into abrasive band by the belt with on conveyer mechanism, conveyer mechanism simultaneously tilts, can also be used for the driven pulley in sbrasive belt grinding mechanism is ground to taper, the tapering of driven pulley in sbrasive belt grinding mechanism, just in time with the tapering of stainless steel cutter blank, mate, only use like this, the cutter blank that the guarantee grinding goes out can meet instructions for use, to improve the grinding accuracy of stainless steel cutter blank;
(2) magneticaction by magnetic worktable, the stainless steel cutter blank is adsorbed on the belt of conveyer mechanism, synchronize with belt by the sbrasive belt grinding zone, when ordering about the stainless steel cutter blank, conveyer belt leaves magnetic worktable when zone, the autodegauss of stainless steel cutter blank, arrive the rear end of conveyer mechanism, according to inertia force direction automatic trip,, from conveyer mechanism, get rid of in feed box;
(3) space between the abrasive band in the belt on conveyer mechanism and sbrasive belt grinding mechanism can guarantee that the tapered forging non-corrodible steel cutter blank of cross section passes through, to guarantee the automatic grinding of stainless steel cutter blank, a grinding can be completed, novel, this still belongs to pioneering on stainless steel cutter blank grinding process, significantly improved production efficiency;
(4) operation of sbrasive belt grinding mechanism only needs the power of several kilowatts, and comparing traditional milling drum needs the power of 30 kilowatts of effects, and power consumption is lower, and is more energy-conservation;
(5) in the sbrasive belt grinding process,, by the spray water quench, be difficult for forming flue dust, and the recyclable recycling of cooling meeting, environmental protection and energy saving more.
