FIELD: press equipment. ^ SUBSTANCE: invention relates to the metalforming equipment, particularly to the mechanical press. The press contains the drive shaft with an eccentric and the ring gear assembled inside the body legs, the connecting rod conjugate with the drawing slider, and the hold-down slider. Inside the slider's big head, the eccentric boss is installed, which has the dentated rim and shoulders. The number of teeth of the ring gear of the drive shaft is twice as less than the number of teeth of the dentated rim of the said boss. The two-shouldered levers are installed at the body. The corresponding side sliding bar is attached to the each lever shoulder, via clevis. The side sliding bars are pivotally connected with the side connecting rod. Each of these connecting rods is pivotally connected with another shoulder of the two-shouldered lever. In the lower position of the hold-down slider, the clevises are placed perpendicularly to the sliding bar's movement. The eccentric consists of two parts. The eccentric boss is installed inside the big head of the connecting rod, which is conjugated with the drawing slider and clasps the part of the eccentric. The boss shoulders correspond to the eccentric parts and installed inside the big heads of the side connecting rod. ^ EFFECT: press productivity and depth of the drawn products are increased. ^ 3 dwg |
