Description
Technical field
The invention belongs to tool sharpening technology field, be specifically related to a kind of sbrasive belt grinding technique of forging non-corrodible steel cutter blank.
Background technology
Cutter blank for processing kitchen knife is divided into two kinds: one is that stainless steel materials shearing forms, and another kind is the stainless steel cutter blank through forging.The cutter blank thickness of stainless steel materials shearing is consistent, can large-scale batch production, but with after not easily grind.Stainless steel cutter blank through forging, by forge rear metal material carbide tissue evenly, crystal grain is thinner, and distribute more refinement, and hardness is high, good toughness, wearability, and resistance to impact is better, likes by consumer very much.
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, first emery wheel is slightly polished, people holds cutter blank and slowly grinds on the emery wheel rotated, with diamond dust, fine grinding carries out to cutter blank more repeated multiple times, 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.
China national intellectual property board web is announced a kind of " grinding technique for forging non-corrodible steel knife " by name, the patent No. is ZL200810069557.5, the grinding of this process reform forging non-corrodible steel cutter blank all the time all can only to rely on the present situation of hand grinding, former manual production has been become Mechanized Processing, and production efficiency obtains and greatly improves.The subject matter that this processing method exists is: procedure of processing is more, operation relative complex; Need the power of about 30kw to drive levigator to rotate, power consumption is large; During levigator polishing simultaneously, dust is large, very not environmentally.
Summary of the invention

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
One forges cutter blank magnetic automatic abrasive belt grinding process, comprises the steps:
Step one, select cross section to forge tapered stainless steel cutter blank, heat-treat rear stand-by to stainless steel cutter blank, the stainless steel cutter blank hardness after heat treatment reaches HRC56.
Step 2, making special magnetic automatic abrasive belt milling drum, composition graphs 1---shown in Fig. 2, magnetic belt grinding machine is made up of magnetic worktable 1, conveyer mechanism 2, sbrasive belt grinding mechanism 3, fixed mount 4, handwheel 5, screw-nut body 6 etc.Conveyer mechanism 2 is arranged on magnetic worktable 1, and sbrasive belt grinding mechanism 3 is arranged on the top of conveyer mechanism 2.Conveyer mechanism 2, sbrasive belt grinding mechanism 3 are respectively by respective driven by motor.The driven wheel time interval of conveyer mechanism 2 is arranged, drive stainless steel cutter blank by after travel forward.The left end of conveyer mechanism 2 is hinged on fixed mount 4, conveyer mechanism 2 can be driven to rotate around pin joint by handwheel 5 and screw-nut body 6, thus form the inclined plane of right-hand member higher than left end, are mechanisms that mechanical field is conventional by handwheel 5 and screw-nut body 6, do not repeat them here.By rotating handwheel 5, drive the rectilinear movement of the screw mandrel axial rotation of screw-nut body 6, nut, thus the right-hand member promoting conveyer mechanism 2 slowly upwards lifting, forming inclined plane.Handwheel 5 and screw-nut body 6 both can be arranged on the below of conveyer mechanism 2, also can be arranged on the right side of conveyer mechanism 2; When handwheel 5 and screw-nut body 6 are arranged on the right side of conveyer mechanism 2, the right-hand member that screw-nut body 6 promotes conveyer mechanism 2 by wedge upwards lifts.
The driven pulley of sbrasive belt grinding mechanism 3 is positioned at below driving wheel, and driven pulley is rubber tire, and rubber tire is provided with antiskid groove A.Sbrasive belt grinding mechanism 3 is set with abrasive band.
First, need the rubber tire be ground to by the driven pulley of sbrasive belt grinding mechanism 3 with tapering: as shown in Figure 3, unload the belt on conveyer mechanism 2, repack abrasive band into, the abrasive band of sbrasive belt grinding mechanism 3 is unloaded simultaneously, then rotate handwheel 5, after driving conveyer mechanism 2 to tilt to the angle of needs by screw-nut body 6, start conveyer mechanism 2, by the abrasive band on conveyer mechanism 2, the driven pulley of sbrasive belt grinding mechanism 3 is ground to the rubber tire with tapering.
Then, grinding stainless steel cutter blank again: as shown in Figure 1 and Figure 2, rotate backward handwheel 5, conveyer mechanism 2 is driven to get back to level by screw-nut body 6, unload the abrasive band in belt mechanism 2, load onto corresponding belt, the abrasive band of sbrasive belt grinding mechanism 3 is loaded onto simultaneously, now, the axis of the driven wheel of conveyer mechanism 2 and the driven wheel of 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 ensure that the tapered forging non-corrodible steel cutter blank of cross section passes through.
Step 3, startup conveyer mechanism 2 and sbrasive belt grinding mechanism 3, forging non-corrodible steel cutter blank tapered for cross section is placed on conveyer mechanism 2, and by the magnetic-adsorption of magnetic worktable 1 ensure stainless steel cutter blank with conveyer mechanism 2 belt by after move forward, when through sbrasive belt grinding mechanism 3, by the abrasive band in sbrasive belt grinding mechanism 3, grinding is carried out to the surface of stainless steel cutter blank, be ground to the other end from the one end on cutter blank surface during grinding, spray cooling water with nozzle 7 simultaneously and make cutter blank temperature be no more than 200 DEG C.
Preferably, totally four groups, sbrasive belt grinding mechanism, is not limited to four groups, with 3---be advisable for 5 groups.Four groups of sbrasive belt grinding mechanism 3 time intervals are arranged on the top of conveyer mechanism 2.
In addition, be also provided with collecting tank 8, send into nozzle 7 after being collected by cooling water and reuse, with saving water resource.
Described antiskid groove A twist, is convenient to processing, and skidproof effect is better, also can be straight-line groove etc., because the driven pulley in sbrasive belt grinding mechanism 3 is with tapering, arranges antiskid groove A and can prevent the abrasive band in sbrasive belt grinding mechanism 3 from skidding.
