Abstract

The utility model discloses a reciprocating shaving round cutter, which comprises a plastic knife rest(4) and a round knife blade group. The round knife blade group is put in the matching plastic knife holder. The round knife blade group and the plastic knife holder are separable; The round knife blade group comprises a metal rod(1) and a plurality of blades(2); The blades(2) are evenly distributed and fixed through on the metal rod(1). The utility model has the advantages of accurate positioning, no easy deforming and simple knife edge processing.

Description

The reciprocating type dise knife that shaves

Technical field

The utility model relates to the moving knife device in the AC and DC reciprocating electric razor, the promptly reciprocating type dise knife that shaves.

Technical background

The AC and DC reciprocating electric razor can be divided into the rotary and reciprocating motion type of circumference by the cutter head direction of motion.For the reciprocating motion type electric shaver, its principle majority is that the circumference with motor rotatablely moves to transform by eccentric shaft and becomes the knife rest straight reciprocating motion, makes reciprocal back and forth cutting movement thereby drive blade.

The existing blade of doing straight reciprocating motion directly is fixed on the plastics knife rest with injection moulding process often, forms the monoblock type dise knife.Its shortcoming is: 1, tens of small blades are difficult to accurate location, yielding or sideslip in injection moulding process, and Shooting Technique is time-consuming, effort, and work efficiency is low; 2, blade is injection-moulded on the plastics knife rest and after forming integral body, must uses special-purpose dise knife grinding machine to process blade cutting edge, and difficulty of processing increases, and yield rate is low, production cost is high.

The utility model content

At the prior art above shortcomings, the technical problems to be solved in the utility model provides a kind of blade accurate positioning, not yielding, the simple reciprocating type dise knife that shaves of edge mill processing.

The technical solution of the utility model is: the reciprocating type dise knife that shaves, constitute by plastics knife rest, circular knife group, the circular knife group is enclosed within on the plastics knife rest that is complementary, described circular knife group and plastics knife rest are separable, described circular knife group comprises the blade of a metallic rod and some quantity, and described blade evenly distributes in the mode of wearing and is fixed on the described metallic rod.

As improvement, every being respectively equipped with breach on the apparent surface about the metallic rod of blade two sides, blade is nested on the cylindrical section of projection between the adjacent breach.

As improvement, described plastics knife rest is provided with some to claw, and described claw stretches in the gap between the blade in pairs, and the breach on the metallic rod is blocked.

Beneficial effect: because circular knife group and plastics knife rest are separable, circular knife group available common centerless grinder and special fixture before being inserted in the plastics knife rest grind the processing blade cutting edge, have reduced difficulty of processing and production cost; Be set on the metallic rod because of the circular knife group simultaneously, blade space is fixed and controlled well to blade available dedicated anchor clamps in process of manufacture, thus make blade space evenly, accurate positioning.

The specific embodiment

As shown in Figure 3, embodiment is made of plastics knife rest 4, circular knife group, and the circular knife group is enclosed within on the plastics knife rest, and circular knife group and plastics knife rest are separable, the circular knife group comprises the blade 2 of a metallic rod 1 and some quantity, and blade 2 evenly distributes in the mode of wearing and is fixed on the metallic rod 1.

Shown in Fig. 2-A, B, C, every being respectively equipped with breach a2 on the apparent surface about the metallic rod of blade 2 two sides, blade is nested on the cylindrical section b2 of projection between the adjacent breach.

As shown in Figure 3, plastics knife rest 4 is provided with some to claw 3, and claw 3 front and back are stretched in the gap between the blade in pairs, and the breach on the metallic rod is blocked.

The production procedure of present embodiment is as follows:

1, with Sheet Metal Forming Technology blade is shaped, knife number is by the finished product requirement, and blade makes it reach certain rigidity and intensity through heat treatment.

2, with the metallic rod of aluminium, copper or stainless steel according to the finished size requirement, by as shown in Figure 1, Cutting Length, cut breach b1 and finish tack.

3, the blade that step 1 is made is worn on the breach b1 of the metallic rod that makes to step 2 one to one, and fixes with special fixture, controls spacing well.

4, with mould fashion of extrusion application of force in the middle of cylindrical section a1 (showing) as Fig. 1, make cylindrical section a1 distortion, promptly middle indent is pushed to both sides, is recessed into breach a2 shown in Figure 2 in the centre, both sides are pressed to blade and are close to, and whenever finally be configured as by clamping on cylindrical section b2 by both sides extruding.

5, grind the blade cutting edge of the circular knife group of manuscript 2 formation with common centerless grinder, special fixture.

6, will be through the circular knife group of mill processing and the plastics knife rest assembling that is complementary.

7, will dispatch from the factory after the above-mentioned product inspection.

Claims

1, the reciprocating type dise knife that shaves, constitute by plastics knife rest (4), circular knife group, the circular knife group is enclosed within on the plastics knife rest that is complementary, it is characterized in that: described circular knife group and plastics knife rest are separable, described circular knife group comprises the blade (2) of a metallic rod (1) and some quantity, and described blade (2) evenly distributes in the mode of wearing and is fixed on the described metallic rod (1).

2, the reciprocating type dise knife that shaves as claimed in claim 1 is characterized in that: every being respectively equipped with breach (a2) on the apparent surface about the metallic rod of blade two sides, blade is nested on the cylindrical section (b2) of projection between the adjacent breach.
