Apparatus for die-assisted squeeze-forming, including die structure with relatively movable die parts for accomodating variously sized or shaped workpieces

摘要

A die-assisted squeeze-forming apparatus, for bending hooks of a plate against a container e.g. a tank, is able to be used with various shapes of the plate and container without replacement of the die structure. To that end, the apparatus is provided with a calking die structure which has a plurality of divided, relatively movable dies, each movable die being subject to being individually actuated by an actuator. The preferred embodiment of the apparatus also includes a controlling means which controls the movement of the actuators and a detecting means which detects a feature of the tank which is symbolic of the size and shape of that tank. The electric signal which indicates the feature of the container is applied to the controlling means. Then the controlling means sends a respective controlling signal for controlling the movement of the actuators in order to cause an adequate rearrangement of the shape of the calking die structure should the tank be different in size or shape then the preceeding one.
