Description

In the proposed device, an anchoring table covering the anvil of the hammer is installed by means of hinged racks on the frame connected to the hammer and turning when it is raised around a fixed axis for raising the pairs punched and then moving them in a horizontal plane by means of rotary yjtiopOB acting on the table,

In FIG. 1 is a side elevational view; FIG. 2 is a top view and FIG. 3 view of his back.

In the foundation pillars, a frame is fixed pivotally around a fixed axis d, equipped with ball sockets in which the b-pillars are installed, holding the canting table o, is made. in the form of a frame covering the anvil of the hammer. The free end of the frame g is bolted to the piston of the air buffer g and captured by the hook g, fitted with a protrusion p and connected by means of a cross member to and ti gg with a hammer head. On the frame r - there are two pivot stops -Wj, m, the lower ends of which are connected by a cable with the levers “j,” 21 to the stops at the required angle

tilt to vertical. The upper ends of the stops .Vi,. "2, are designed to rotate the arms o, o, swinging around the fixed axles and provided with forks, which include fingers fixed on the table a, and one of the stops serves to communicate the table" longitudinal movement in horizontal plane and the other transverse.

The hammer head, when lifting, operates by means of a pull. and hook i onto the cancer and makes it rotate around the d axis upward. The table moving together with the frame g, rising above the working surface of the anvil n, picks up a pair of holes punched under the hammer, and the movable stops -MI, m, act on the levers o, o, and make the table move horizontally. The adjustment and activation of the transverse and longitudinal table feed a in the horizontal plane is carried out by setting the levers 2 on one or another angle of deviation from the vertical axis, as a result of which the levers change position — i, -H3. On the path of movement of the hook r, a fixed stop c is fixed on the hammer bed, which produces the hook when

disengaging the latter from the frame. " When the frame r moves downwards, the material placed on the table and held by the working surface of the gasket ni occupies, as a result of the feeding, a new position relative to the hammer head. The swivel supports m, MZ reversely move the table a, and the impact when the frame is falling g is softened by the action of the air buffer g.

The subject of the patent.

1. A device for turning the steam punched under the hammer, characterized in that the canting table, covering the anvil and hammer, is mounted on posts in ball sockets in frame g, rotated around a fixed horizontal axis d by means of hook g, connected l with the hammer head, to move which table and together with the pierced pair in the horizontal plane the frame g

it is equipped with pivot stops: MI, MI, acting when the frame is raised, on the arms O, O, swinging around the stationary axis, the fingers reinforced in the table O, enter into the fork.

2. Application of the anvil c-fixture, described in p. 1, mounted on the hammer base and intended to affect the projection of the hook i in order to turn off the last of the connection with the frame g.

3. Application with the air buffer 3 device described in paragraph 1, which serves to soften the impact when the frame is dropped “after the hook i is turned off.

4. The application of the device for adjusting the supply of the table a in the horizontal direction, consisting of levers and, "1, connected by a cable with the levers MI, MS, whose deviation from the vertical axis regulates the amount of movement of the table and in the horizontal plane.
