Description

A kind of processing method of tubular moving head for reciprocating razor

Technical field

The present invention relates to a kind of processing method of tubular moving head for reciprocating razor.

Background technology

Present tubular moving head for reciprocating razor is that the vertical tube axis cuts out rule cutter tooth seam on metal pipe, form a rule cutter tooth between the adjacent cutter tooth seam, the intersection, two sides of the outer surface of cutter tooth and cutter tooth forms two cutting edges, this processing method mainly is applicable to the metal tube that processing is thin, and the cutting anterior angle of processing the cutting edge of resulting pipe cutter is a zero degree, cutting edge is sharp inadequately, therefore existing processing method, the tubular moving head intensity that obtains is relatively poor, cutting edge is sharp inadequately.

Summary of the invention

The purpose of this invention is to provide a kind of processing method that can process the tubular moving head for reciprocating razor thicker, that intensity better, cutting edge is sharper.

To achieve these goals, technology solution of the present invention is such: a kind of processing method of tubular moving head for reciprocating razor, its process may further comprise the steps successively: A, stamp out the groove of zebra wire at metal plain film middle part, depth of groove is more than or equal to the thickness of metal plain film; B, the metal plain film is bent to tube shape, the zebra linear recess is arranged in order along the length direction of pipe, and the groove back side is towards the pipe outside; C, be that the epirelief in the pipe outside partly grinds off, make the epirelief in the pipe outside partly expose rule cutter tooth seam, be cutter tooth between two adjacent cutters tooth seams the groove back side in the pipe outside; D, pipe cutter and plastic stent are fixed with pressure.

Since in the above-mentioned technical solution by stamped metal plain film, bending, roll flute, process such as be press-fitted, can carry out punching press, crooked, roll flute then to thicker sheet metal fully on the processing technology, also can form the cutting anterior angle of cutting edge easily, therefore can make things convenient for, economical, feasible process thicker, intensity better, tubular moving head for reciprocating razor that cutting edge is sharper.

The specific embodiment

Below in conjunction with drawings and Examples the present invention is described in further detail:

Wherein: 1, tool rest; 2, cutter tooth; 3, cutter tooth seam; 4, cutting edge; 5, top margin; 6, plastic stent; 7, end face; 8, jointing line; 9, groove; 10, the groove back side.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the metal plain film stamps out the groove 9 of zebra wire through following steps: A, at metal plain film middle part, and groove 9 degree of depth are more than or equal to the thickness of metal plain film; B, the metal plain film is bent to tube shape, zebra linear recess 9 is arranged in order along the length direction of pipe, and the groove back side 10 is towards the pipe outside; C, be that the epirelief in the pipe outside partly grinds off, make the epirelief in the pipe outside partly expose rule cutter tooth seam, be cutter tooth between two adjacent cutters tooth seams the groove back side 10 in the pipe outside; D, pipe cutter and plastic stent are fixed with pressure; Finally obtain pipe formula dynamic cutter head.Wherein the first half among Fig. 4 is ground off in the C step, can form cutter tooth seam 3 and cutter tooth 2 among Fig. 5.

For the cutting edge that makes pipe formula dynamic cutter head has certain cutting anterior angle, can described in front A step in, the transverse shape of groove 9 that makes the punching press of metal plain film institute is for falling isosceles trapezoid.For the intensity of strengthening tubular moving head, hardness, toughness can be after the B step, pipe is heat-treated before the C step.The seam crossing of pipe cutter can be welded as a whole, also can not weld after the bending of metal plain film, then should be after the B step, carry out before the heat treatment if carry out soldering.

As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, tubular moving head for reciprocating razor comprises plastic stent 6, tool rest 1, cutter tooth 2, cutter tooth seam 3, the intersection, two sides of the outer surface of cutter tooth 2 and cutter tooth 2 forms two cutting edges 4, and the cutting anterior angle of cutting edge 4 is greater than zero degree and less than 90 degree.The direction of motion of this dynamic cutter head is consistent with the length direction of pipe cutter, wherein the cutting anterior angle a of cutting edge 4 is the vertical plane of cutting direction line and the angle of cutting edge 4 sides, dynamic cutter head its cutting edge 4 in reciprocal cutting movement has certain cutting anterior angle, thereby can be sharp, do not have pain ground and cut off beard, the cutting edge anterior angle had positive effect sharper, more energy-conservation, that the skin sense is good for the tubular moving head that the tubular moving head this patent of zero degree provides relatively in the past.

As Fig. 7, shown in Figure 8, it is the wideest that cutter tooth 2 cross sections of the tubular moving head in this patent obviously have top margin 5, from top margin 5 characteristics that narrow down gradually of the cross section of cutter tooth 2 down, helps forming the cutting anterior angle of cutting edge 4 like this.Cutter tooth 2 cross sections of tubular moving head just in time form a up big and down small isosceles trapezoid among Fig. 7, Fig. 8 from geometric figure.

The cutting edge 4 cutting anterior angles that tubular moving head provided by the present invention can be determined respective angles according to different use objects and demand, its cutting anterior angle can be selected five degree, ten degree, 15 degree, 25 degree, 35 degree, 45 degree, 55 degree, 65 degree, 75 degree, 80 degree for use, a large amount of experiments, comparison through the inventor, the inventor recommends when the cutting anterior angle is spent greater than 30 degree and less than 65 cutting effect relatively desirable, and result of use is the most satisfied when the cutting anterior angle is defined as spending and spending less than 62 greater than 55.

Have a continuous jointing line 8 between the both ends of the surface 7 of the tool rest 1 of pipe formula dynamic cutter head, from this jointing line 8 pipe formula dynamic cutter head separately being shakeout promptly becomes a rectangular planes blade, and cutter tooth 2, cutter tooth seam 3 are positioned at the middle part of rectangular planes blade after shakeouing.Have a continuous jointing line 8 between the both ends of the surface 7 of above-mentioned tool rest and can be the butt weld of two parts tool rest 1, also can be that two parts tool rest 1 is pressed close to the gap line in the middle of the back.Because pipe formula dynamic cutter head is a kind of new-type cutter head of reciprocating razor rise near-mid term, effect is also relatively good, because its processing is to form cutter tooth and cutting edge by cutting on pipe, therefore the technical staff has formed a custom viewpoint in thinking, and method provided by the invention is reasonable, broken through this thinking habit dexterously, this method is thicker except processing, intensity is pipe formula dynamic cutter head preferably, this method old processing method relatively in the past also is particularly suitable for processing the tubular moving head that cutting edge has certain cutting anterior angle, therefore this dynamic cutter head does not have when the cutting beard and breaks, the process that squeezes off, but it is sharp, at a high speed, there is not pain ground instantaneous trip, and can also obviously cut down the consumption of energy with respect to original pipe formula dynamic cutter head, can obviously prolong the service time of dry cell or rechargeable battery, because its cutting edge has the cutting anterior angle, this dynamic cutter head does not influence sharpness after using a period of time mild wear, still maintain the cutting anterior angle, has the sharp more autogenous grinding function of mill more, in addition because this tubular moving head has sharp cut-out ability, therefore it is dense that the shaver of equipping this cutter head can adapt to American-European crowd's beard more, slightly, close characteristics can improve the export competitiveness of product.
