The upper surface of fixed frame offers the first mounting groove, and the bottom of the movable plate is equipped with corresponding with the first installation groove location the
Two mounting grooves are additionally provided with telescopic rod, the second bullet are socketed on the telescopic rod between second mounting groove and the first mounting groove
The both ends of spring, the second spring are respectively and fixedly installed in the second mounting groove and the first mounting groove, two movable plates it
Between also flexible connection there are two connecting rod.
Preferably, the punching structure includes the punch retainer mounted on upper die holder bottom, the punch retainer
Bottom is equipped with punching press punch-pin, and the lower section of the punch retainer is equipped with stripper, and the upper die holder is also extended through equipped with bolt, and
One end of bolt also extends through fixed frame and is connect with stripper, and the first spring is socketed on the bolt, and the punching press punch-pin is remote
One end from fixed frame is through stripper and extends to the lower section of stripper, and punching press punch-pin can extend to it is recessed in concave template
Preferably, sliding slot is offered on side opposite between two movable plates, the both ends of the connecting rod are equal
Equipped with the sliding block that can coordinate installation with sliding slot.
Preferably, the telescopic rod includes the casing being mounted on inside the second mounting groove, and described sleeve pipe is far from movable plate
One end fits grafting slide bar, the one end of the slide bar far from casing are mounted on the inside of the first mounting groove.
Preferably, for the bottom bonding of the fixed frame there are two rubber pad, two rubber pads are respectively positioned on concave template concave
The both sides of slot.
A kind of anti-deformation machined die proposed by the present invention, advantageous effect are：By the way that fixed frame and work is added
Movable plate is fixed material in punching press for the material to required punching press, can be pushed away in this way in movement to avoid metal material
Contact when going out with concave template, to avoid the abrasion to concave template；It, in this way can be square by the way that telescopic rod and second spring is added
Just so that movable plate resets, to facilitate the release of stamping material after the completion of to material punching press.The configuration of the present invention is simple,
It is easy to use, the friction to concave template can be not only avoided when releasing material, moreover it is possible to prevent cavity plate from deforming, to avoid punching press
The deformation of part afterwards.
