Summary of the invention
To above-mentioned deficiency, the utility model is exactly that a kind of stationary knife of processing simple multi-head rotary electric shaver will be provided.
The stationary knife of a kind of multi-head rotary electric shaver that the utility model provides; Include the circle wall of tubular and porose roof; Be to be combined by the cap shape part that encloses wall and roof same thickness and the second circle wall, the said second circle wall is supported in the circle wall on the cap shape part and with interference fit, welding, bonding or riveted joint and interfixes.
The stationary knife of a kind of multi-head rotary electric shaver that the utility model provides, will enclose wall be divided into two-layer, one deck and roof one, another the layer as stiffening ring, two kinds of different wall thickness of desired circle wall and roof are confirmed on raw material.Compared with prior art, the utility model processing is simple, few, the precision easy master of spillage of material, when the electrolysis perforate electrolysis wasting of resources few, overall cost is descended.Simultaneously, the pore wall thickness on the whole stationary knife is consistent, makes shave stay root all definite and shorter with thin roof thickness, obtains higher shave efficient and sense of touch.Also because the processing skiving quantitative change of roof face very little; Make working (machining) efficiency improve more than 20 times; And can be because of the cutting degree change than the big material hardness that do not make, the deflection that causes because of metalworking descends, precision improves, sharpness, noise and all obviously improvement of shearing skin sense during use.
The outside of the said second circle wall upper edge is no more than the limit of outermost marginal pore on the roof; The inboard is lower than the acutance of the outside and formation less than 30 °; The shape of the second circle wall upper edge makes stationary knife circle wall and inboard, roof knuckle place that an endless belt that outwards enlarges arranged; Make that not only there is the thickness the same with other parts in the hole in the marginal portion of stationary knife on the roof, and do not enclose the obstruction of wall in the hole.And in the prior art, as shown in Figure 3, cap shape part 11 has the plane 1b because of the circle wall thickness of hobbing feed formation because of hole 1a on the roof at circle wall one end, makes beard 3 not get into tool bore from nose end.Thereby this structure of the utility model solved the deficiency that beard (particularly long beard or volume beard) can not get into the hole fully, further improved the efficient that shaves.
