Definitions

  • the present invention relates to a manufacturing process, and more particularly to a manufacturing process for a razor and a razor blade net and a razor blade.
  • rotary razors have a good adaptability, they are now more and more popular in the market. With the continuous development of electric shavers, the processing of knife nets has become an urgent need for improvement and research in the industry.
  • the razor of the rotary razor is a thin-walled shallow grooved part. Requires uniform thickness of the mesh surface 0.1mm, only 0.1mm thick mesh shaving, to ensure comfort and ensure cleanliness.
  • the early appearance of the knife-net structure in the form of a plane, in order to ensure the overall structure of the knife net, is 0.5mm.
  • the thickness of the metal sheet is obtained by integrally drawing and drawing the blank, and then processing the mesh joint, and then heat-treating, and then performing batch grinding and grinding of the surface portion of the knife. Make the mesh surface evenly 0.1mm
  • the requirement is that the lower housing can have a larger thickness. Since the contact surface with the skin is a flat structure, there are many general-purpose devices and it is easy to measure, making it easier to monitor in the mass production process. Advantages:
  • the mesh surface is in a flat surface, which is ideal for short-term effects. Disadvantages: The performance of the long-shoulder capture ability is general, it is easy to have a pulling feeling, and the skin feel is poor.
  • the blade-shaped knife net is also made with 0.5mm.
  • the thickness of the material, the whole stamping and drawing to obtain the blank, the mesh joint processing, and then heat treatment, using special equipment for independent grinding, grinding, so that the entire mesh surface to reach the desired 0.1mm The requirement is that the lower casing gets a greater thickness.
  • the net surface obtained by this method can only achieve a thickness of 0.1mm at a certain point, but the entire arc surface wants to achieve a uniform 0.1mm.
  • the thickness is difficult to achieve by using the above manufacturing process. Because of its curved surface structure, this kind of knife net has good performance on the ability to capture long and short beards, and has a good skin feel.
  • the arc surface is difficult to manufacture, the manufacturing cost is high, and the effect is not ideal, which is not conducive to the development of this industry.
  • the present invention provides a manufacturing process of a razor and a razor blade net and a razor blade net, which mainly solves
  • the existing curved surface knife net is difficult to manufacture, the manufacturing cost is high, and the effect is not ideal, which is not conducive to the development of this industry.
  • a razor blade net including a stencil mesh surface and a stencil mesh housing, wherein the stencil mesh surface is provided with a plurality of mesh joints, and a lower portion of the stencil mesh surface has a welded portion, and the stencil mesh housing has an annular shape,
  • the lower edge of the knife net shell is integrally formed with a snap ring, and the net surface of the knife net is sleeved on the upper part of the wire mesh housing and welded to the wire mesh shell through the welded portion.
  • the blade mesh surface is welded with a blade positioning platform, and the blade positioning platform is located on an inner surface of the mesh surface of the blade.
  • the blade mesh housing is provided with an annular groove adapted to the welded portion.
  • a razor comprising a housing, a power source, a motor, and a transmission controlled shaving assembly, The razor is provided with the razor blade mesh.
  • a manufacturing process for a razor blade net comprising the following steps: a Taking material: preparing a metal sheet having a first thickness and a metal sheet 2 having a second thickness; b, drawing the mesh surface of the knife net: drawing the metal sheet into the mesh surface of the knife and the knife a welded portion extends from the edge of the mesh surface; c Stretching of the stencil shell: the metal sheet is stretched to form a stencil shell, the stencil shell is annular, and the lower edge of the stencil shell is formed with a snap ring; d, Welding: welding the wire mesh surface to the wire mesh housing; e Heat treatment.
  • the seam is machined on the mesh surface of the stencil before heat treatment after welding.
  • the mesh seam is produced by a cutting process.
  • the mesh seam is processed by an etching process.
  • the mesh joint is produced by electrolytic processing.
  • the seam is made by stamping.
  • the blade positioning table is welded at the center of the inner surface of the wire mesh surface before the wire mesh housing is stretched after the wire mesh surface is drawn.
  • Deburring is performed after the heat treatment is completed.
  • the stencil mesh surface is shallowly stretched by the convex part of the mold on the middle portion of the metal sheet to produce a curved surface.
  • the wire mesh housing is machined with an annular groove adapted to the welded portion.
  • the metal sheet 1 is made of a stainless steel material and has a thickness of 0.1 mm.
  • the metal sheet 2 is made of a stainless steel material and has a thickness of 0.5 mm.
  • the invention has the beneficial effects that the whole processing method is not used, and the knife net is processed into two parts, and then the two parts are completely combined by the welding process, and the uniformity of the mesh surface is good, and the whole mesh surface can be ensured.
  • the curvature which improves the comfort and cleanliness of the shaving, the shell part is processed to a thicker thickness than the web part (eg 0.5mm), which guarantees the strength of the entire net cover.
  • Figure 1 is an exploded view of the razor blade.
  • Figure 2 is a cross-sectional view of the razor blade.
  • Figure 3 is a perspective view of the razor blade web.
