Crown 11 carries out intensive focusing (weldering source), and the range of high-temperature fusion, to external diffusion, possesses radius R with the center of circle, because of practical feelings
The error of operation is had in condition, the range of the melting of the welding just arrives the edge positions of the upper surface of stationary knife crown 8, Huo Zheyue
The edge positions for crossing the upper surface of stationary knife crown 8 are package stationary knife crown 8, wherein the technical parameter packet of laser welding process
It includes：Laser welding frequency is 30 times/s, and laser acc power is 200w, pulse width 2.5ms, pulse energy 60J.(4) lead to
Cross one end that guide rail interconnecting piece 22 is fixed in moving knife portion 3 by laser welding process.(5) by laser welding process by guiding rail
21 are fixed on fixed part 4；(6) driving portion 20a is snapped connection with 22 other end of guide rail interconnecting piece；This implementation uses above-mentioned laser
Welding procedure processing method, being easily deformed etc. for thin blade caused by when avoiding being processed using existing polishing process are lacked
It falls into, in addition, because stationary knife portion 2 is ultrathin design, thickness is only 0.05-0.5mm, rigidity itself is insufficient, fixed in the present embodiment
Crown 11 and 8 welding of stationary knife crown, in 3 shear history of moving knife portion, stationary knife cutter tooth portion 6 not will produce be easily deformed lifted up and from
The problem of starting 3 shear surface of knife portion ensure that trimmer works normally.
Example IV：
A kind of manufacturing method in the trimming portion that the present embodiment is provided for above-described embodiment two, includes the following steps：
S1：Moving knife portion 30 is installed in moving knife receiving portion 50；S2：Stationary knife portion 20 is installed in fixed part 40 towards moving knife portion 30；
S3：Welding fixes crown 110 in stationary knife crown 80.Specifically, installation moving knife portion 30 is in moving knife receiving portion 50, towards moving knife portion 30
Stationary knife portion 200 is installed in the card slot 40a of fixed part 40,90 one-to-one position of stationary knife cutter tooth portion 60 and fixed teeth portion is adopted
Intensive focusing is carried out to fixed crown 110 with laser welding process and is fused to stationary knife crown 80, processing forms end face smoothly and is in
The weld portion 120 of arc surfaced.
More specifically, most common but unrestricted steps are as follows：(1) it is accommodated in the moving knife of the fixed part of trimmer 40
Moving knife portion 30 is installed in portion 50.(2) stationary knife portion 200 then is installed in the card slot 40a of fixed part 40 towards moving knife portion 30, card slot
40a and the 80 transition cooperation of stationary knife portion or clearance fit so that the stationary knife cutter tooth portion 60 in stationary knife portion 200 and fixed teeth portion 90 are one by one
It is corresponding.(3) it uses laser welding process to carry out intensive focusing to fixed crown 110 and is fused to stationary knife crown 80, processing forms end
Face is smooth and is in the weld portion 120 of arc surfaced, and welding is carried out to fixed crown 110 with the laser welding frequency of 30 times/s so that
To the 110 quickly and evenly welding within the shortest time of fixed crown, by the surface tension of liquid under high temperature fused state
Naturally it is rolled into round and smooth arcuation, fixed crown 110 is fused to the processing of stationary knife crown 80 and forms weld portion 120.Fixed crown 110
It is rolled into round and smooth arcuation naturally by the surface tension of liquid under high temperature fused state and is fused to stationary knife crown 80, there are two types of
Realization method, one is carry out intensive focusing (weldering source), the range of high-temperature fusion is with the center of circle to extending out in fixed crown 110
It dissipates, possesses radius R, because having the error of operation in actual conditions, the range of the melting of the welding just arrives stationary knife crown 80
Upper surface edge positions, or cross the edge positions of the upper surface of stationary knife crown 80, be package stationary knife crown 80,
In, the technical parameter of laser welding process includes：Laser welding frequency is 30 times/s, and laser acc power is 200w, pulse width
For 2.5ms, pulse energy 60J.(4) moving knife portion 30 is fixed on to one end of rotary shaft 23 by laser welding process.(5) it drives
Dynamic portion 200a is snapped connection with axis connection portion 24.This implementation uses above-mentioned laser welding process processing method, avoids using existing
The defects of being easily deformed of thin blade caused by when some polishing processes are processed, in addition, because stationary knife portion 200 is ultra-thin sets
Meter, thickness is only 0.05-0.5mm, rigidity itself is insufficient, and crown 110 and 80 welding of stationary knife crown are fixed in the present embodiment, dynamic
In 30 shear history of knife portion, stationary knife cutter tooth portion 60, which not will produce, is easily deformed the problem of having lifted up and left 30 shear surface of moving knife portion,
It ensure that trimmer works normally.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be appreciated by those skilled in the art that can technical scheme of the present invention be modified or be waited
With replacing, without departing from the objective and range of the technical program, should all cover in scope of the presently claimed invention.
