Abstract
The invention declares a mechanical press with a self-lock worm mechanism, which controls the horizontal movement of a piston and friction plates through the on/off of a two-position three-way electromagnetic directional valve on an air passage, in combination with the elastic force of the springs. According to the invention, the friction plates are in a braking state when being jointed and the self-locking of the worm is realized, so as to ensure safety operation and stamping precision of the mechanical press; when the friction plates are released, the worm can rotate; an upper die adjusting system of the mechanical press can operate; and a braking body can be under remote monitoring of a pressure relay, and interlocking together with other actions in the press is realized. The mechanical press has the benefits that the structure is compact; the driving motor of the piston dispenses with a braking motor, which saves the installation space; and the situation that the press has a smaller slide block is more practical. Meanwhile, the mechanical press can be widely used in equipment with self-locking requirements; the intensity of the spring braking force can be adjusted through horizontal adjusting of the adjusting nuts, so as to ensure the braking effect.
