Described punch-pin is the arc-shaped rod with the arc stamping surface that matched with workpiece shapes, and upper die plate is installed and worked on a hydraulic press
The bottom of platform；The adjustment backing plate for adjusting the coefficient of resilience, the adjusting pad are additionally provided between described punch-pin and lower mould bottom plate
Plate is fixedly mounted in lower mould bottom plate；The invention has error small, and high precision, operation is few, efficiency high, the spy of low production cost
Point, may be adapted to mass production.
The content of the invention
Dress is processed it is an object of the invention to provide smaller, the easy to operate bucket of a kind of simple structure, required operating pressure
Put.
To achieve the above object, the technical solution used in the present invention is to invent a kind of bucket shaping dies, including fixation
Mould 14 and dynamic model 10, also include dynamic model oil cylinder 6 and mold base；The mold base includes dynamic model oil cylinder seat base plate 1, die bottom plate
4 and dynamic model revolution bearing pin base 7, the bottom of the dynamic model oil cylinder seat base plate 1 and the right part of die bottom plate 4 are connected as a single entity, described
Stent 14 and dynamic model revolution bearing pin base 7 are separately mounted to left part and the middle part of die bottom plate 4；At the dynamic model oil cylinder seat bottom
The top of plate 1 is also equipped with dynamic model oil cylinder tailstock 2, and the external part and tail end of the dynamic model oil cylinder 6 cut with scissors mounted in the side of dynamic model 10 respectively
On the dynamic model oil cylinder axis pin base 9 and dynamic model oil cylinder tailstock 2 on side；The bottom hinge of the dynamic model 10 is mounted in dynamic model revolution bearing pin base 7
On；The convex curve 15 and sag vertical curve 12 of mutual cooperation are respectively arranged with the stent 14 and dynamic model 10.
The base plate for being additionally provided with more than two in the inner side of sag vertical curve 12 of the dynamic model 10 rolls bearing pin 13.
Die bottom plate is additionally provided with the lower inside of dynamic model oil cylinder seat base plate 1 and the right part top of die bottom plate 4 to strengthen
Muscle 5, the top of die bottom plate reinforcement 5 and the left side respectively with dynamic model oil cylinder tailstock 2 below and dynamic model revolution bearing pin base 7
The right connects.
Bucket shaping dies of the invention, using the dynamic model of rotary motion, thus, its structure is relatively simple.Meanwhile, into
During shape, dynamic model oil cylinder pushing dynamic model and is rotated around dynamic model centre of gyration bearing pin, on the one hand, allow bucket bottom steel plate by planar shaped
Curved surface is gradually deformed into, thus, required pressure is smaller；On the other hand, dynamic model oil cylinder is to promote dynamic model to be turned round around dynamic model
Central pin shaft rotates, and increases the arm of force of dynamic model, therefore further reduces required pressure；Another further aspect, in the concave curved of dynamic model
Line inner side is additionally provided with many foundation plates and rolls bearing pins, substantially reduces frictional force when dynamic model sag vertical curve slips over bucket bottom steel plate, therefore
Again reduce required operating pressure.Additionally, during operation, only need to be by bucket bottom steel plate insertion stent and dynamic model revolution bearing pin bottom
In gap between seat, starting dynamic model oil cylinder can be once-forming, therefore, its operation extremely convenient.
