Put, and by being discharged positioned at lower mould correspondence position through small opening, complete a knife punch forming.
It is further characterized by：Flat cutter is arranged to the upper forming surface of lower mould, the lower forming surface of upper mould is corresponding to described
The upper forming surface arrangement of lower mould, the top of upper mould are circumscribed with forcing press, and the position that the upper mould corresponds to preset hole is provided with down
Convex red needle, the red needle are provided with vertical direction outer shroud week by spring driven de- material block, and the de- material block is in matched moulds
Shi Shanghang is retracted in the upper cavity of mould, correcting red needle, and the de- material block is ejected under the thrust in die sinking in spring and completed
De- material, the position that the lower mould corresponds to the red needle are provided through small opening, and the waste material in the hole being stamped out passes through through leakage
Discharge in hole；
It is further characterised by：The de- material block is fixedly installed at the upper part with the de- material push rod being vertically arranged, described de-
Expect that push rod runs through the line channel position of fixed block, the fixed block is installed in the upper mould, the top pressure of the de- material push rod
Equipped with linear springs, the upper end of the linear springs is fixed, it is ensured that the elastic force of linear springs drives de- material block straight line to action；
The lower template of the lower mould is placed with punching corresponding to the position of the red needle and enters block, and the punching enters block and corresponded to
Top is provided with immediately below the red needle and runs through small opening, the lower template is installed in the upper surface of the die shoe, the punching
Hole enters block and is embedded in the penetrating mounting holes of the lower template and is supported on the upper surface arrangement of the die shoe, the die shoe
The position of small opening is provided with bottom corresponding to top and runs through small opening, the top is combined through small opening, bottom through small opening
Run through small opening described in being formed.
After technology using the present invention, while due to forcing press stamping products profile, at the design position of product simultaneously
Hole is formed, and the waste material in hole is discharged, it is achieved thereby that a knife punch forming of product so that product size precision improves, punching
Press efficiency to improve, improve yield, reduce production cost.
