Plate, bottom plate is fixedly installed below the movable plate, and two shaped inserts being oppositely arranged pass through the loose plug and bottom
End is fixed in the movable plate, and institute is fixed on after sequentially passing through the bottom plate and movable plate from top to bottom in the top of contour screw
It states in loose plug, is provided with the cavity for accommodating the contour screw in the loose plug, on the inner wall of the cavity
It is provided with annular protrusion, bolt head and the portion for being stated contour screw are accommodated in the cavity on the annular protrusion top
Divide shank of bolt, is cased with elastic component, the work on the shank of bolt accommodated in the cavity of the annular protrusion lower part
It is provided with movable holddown above dynamic insert, is provided with square protruding, the square protruding below the middle part of the movable holddown
Above the loose plug between two shaped inserts, the inner wall of the outer wall of the square protruding and shaped insert it
Between gap for clamping material strip both sides, movable pin passes through the square protruding, the two sides of the movable holddown be provided with plus
Pressure device.
The pressurizing device includes cylinder.
It is overlap joint between the loose plug and movable plate.
The shaped insert is L-type, and the vertical section of the L-type passes through the loose plug, and the horizontal segment of the L-type is located at
In the movable plate.
Top flush with the shaped insert after the loose plug floats under the action of the elastic member.
The outer diameter of the elastic component is greater than the internal diameter of the annular protrusion.
The elastic component includes compressed spring or rubber sleeve.
A kind of stamping die, wherein including above-mentioned primary bilateral 90 degree of benders.
Working principle of the present invention is as follows: when die sinking, loose plug under the action of the elastic member, floats flat with shaped insert
Together；When molding, movable holddown and movable pin move downward simultaneously, and movable pin pushes down material strip, and movable holddown continues fortune downwards
It is dynamic, drive material strip and loose plug downward simultaneously, shaped insert remains stationary at this time, by movable pin and shaped insert come complete
90 ° of bendings are carried out to product both sides at a step.
A kind of primary bilateral 90 degree of benders and stamping die, movable holddown therein provided by the invention are used for
Bending and molding, movable pin are used to form for pushing down material strip bottom, loose plug for controlling bending angle, shaped insert,
Movable plate is used for installation activity insert and shaped insert, and bottom plate is for fixing loose plug, shaped insert and movable plate, contour spiral shell
Silk, cavity and annular protrusion float highly for controlling loose plug, for clamping material strip between movable holddown and shaped insert
Both sides；The present invention occupies little space in mold, material strip in the spatial dimension of existing mold can smooth punch forming, structure
Simply, operation work step simplifies, and 90 degree are bent into form quotient height.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
