Abstract

A machine provided with a bed on which is mounted a frame having an explosion chamber communicating with the space of a power cylinder whose plunger supports a punch, an anvil block located opposite to the punch and carrying a die arranged coaxially with the punch, and a device for returning the plunger to the initial position. The frame and the anvil block are rigidly secured on the bed, the space of the power cylinder is open at both ends and a hole providing communication between the space, the explosion chamber is located substantially in the middle of the length of the space, the plunger supporting the punch and a second similar plunger with a second punch being installed in the space opposite to the axis of the hole while a second anvil block is rigidly installed on the bed opposite the second punch symmetrically with the first anvil block relative to the same axis, the second anvil block being rigidly connected to the first anvil block and carrying a rigidly-secured second die. Due to the rigidity of its design, the machine ensures a higher working precision, efficiency and durability than other machines of the same type.

Claims2

Dependent claims

A machine for high-speed plastic working of materials utilizing the energy of explosion comprising:

a. a bed;
b. a frame rigidly secured on said bed, said frame having an explosion chamber and a power cylinder space, said space being open at both ends and a hole having an axis located substantially in the middle of the length of said space providing communication between the space and the explosion chamber;
c. two similar plungers mounted in the power cylinder space opposite to the axis of said hole and moving in synchronism in opposite directions under the force of high-pressure gases liberated by an explosion of a working medium in said explosion chamber and entering said power cylinder space through said hole;
d. two similar punches secured on said plungers opposite to each other;
e. two similar anvil blocks, each block being rigidly secured on said bed opposite to one of said punches symmetrically with the other of said anvil blocks relative to the axis of said hole and rigidly connected therewith;
f. two similar dies, each die being rigidly secured on one of said anvil blocks opposite to and coaxially with the respective punch;
g. and means for returning said plungers with said punches to the initial position.
