Specific embodiment
Shown in reference picture 1- Fig. 3, a kind of motor stator core laser automatic welding with separate high-speed stamping die, it includes
Upper die and lower die 1, stock guide 2, blanking die 3, described lower mould 1 include from top to bottom concave template 4, die backing plate 5, clamp ring 6,
Die shoe 7, blanking die 3 is arranged in concave template 4, and clamp ring 6 is located at below blanking die 3, and clamp ring 6 is axially arranged with locking
Hole 6.1, blanking die 3 is relative with locking hole 6.1, and clamp ring 6 internal diameter is less than blanking die 3 internal diameter, and clamp ring 6 frame is placed on lower mould
In seat 7, it is provided with products export 7.1 below die shoe 7, locking hole 6.1 lower end is communicated with products export 7.1；It also includes welding
Assembly, described weld assembly includes laser welding light emitters 8, and laser welding light emitters 8 are located at die shoe 7 side
Face, the side of die shoe 7 and clamp ring 6 is provided with and facilitates the light in laser light irradiation stamping 11 in locking hole 6.1 to lead to
Road 9.
The inner port vertical height of described light channel 9 is more than the thickness of monolithic stamping 11, less than biplate stamping
11 thickness.
Described light channel 9 is in big horn-like in inner little outer end.
Described light channel 9 refers to that die shoe 7 side offers UV light passage 7.2, and clamp ring 6 side wall is provided with interior light
Line passage 6.2, interior light channel 6.2 inner port is communicated with locking hole 6.1, and external port is communicated with UV light passage 7.2.
Described weld assembly also includes finely tuning fixed seat 10, and laser welding light emitters 8 are arranged on fine setting fixed seat
On 10, fine setting fixed seat 10 is arranged on die shoe 7 side wall through support.
Described fine setting fixed seat 10 includes supporting frame 10.1, slide 10.2, adjusting screw rod 10.4, slide 10.2 slide fit
It is combined on supporting frame 10.1, laser welding light emitters 8 are arranged on slide 10.2 upper surface, adjusting screw rod 10.4 spiral shell coordinates
In the afterbody of supporting frame 10.1, the inner of adjusting screw rod 10.4 is connected with the outer end of slide 10.2.
The operation principle of the present invention is：Described plate comes from stock guide 2, is thrust by the drift on upper mould, stamping
11 fall in blanking die 3, and stamping 11 falls in clamp ring 6 with self gravitation, because clamp ring 6 internal diameter is recessed less than blanking
Mould 3 internal diameter is that is to say, that the diameter of stamping 11 is more slightly larger than the locking hole 6.1 of clamp ring 6, so stamping 11 will not at it certainly
Drop under heavy sensation of the body power, with increasing of stamping 11, the stamping 11 of bottom moves downward under upper die punch effect, drift
Action every time, the stamping 11 of bottom all can move down the stroke of stamping 11 thickness, and is collected in clamp ring 6
Interior, with frock clamp, stamping 11 need not be superimposed fixation again, the present invention realizes the voluntarily collecting function of stamping 11, permissible
Greatly reduce later stage cost of labor；After the stamping 11 of bottom enters into the scope that light channel 9 can be irradiated to, laser
Adjacent stamping 11 is welded by welding light emitters 8 transmitting laser beam, realizes automatic welding, improves work efficiency.
When required stamping 11 is superimposed quantity and reaches required thickness, laser welding light emitters 8 stop transmitting laser beam,
That is midway stops primary emission laser beam, then the stamping 11 that two of which will be connected is not welded, so weldering
That part connecting comes off from locking hole 6.1 under drift works on, and drops out from the outlet 7.1 of die shoe 7.
