SU114491A1 - Blacksmith Hammer with Vibrating Head - Google Patents

Description

Forging hammers with a vibrating hammer, equipped with a bed, upper and lower die heads and eccentric shafts for vibration of the upper die are known.

However, in such hammers the bed is not loaded with the weight of moving and stationary parts, which leads to an increase in the weight of the installation and worsens its operating conditions.

The described blacksmith hammer does not have the indicated disadvantages. This is achieved by using a slider to apply a vibrating striker to the workpiece to be stamped.

FIG. 1 is a front view of a blacksmith’s hammer; in fig. 2 is a section along AA in FIG. one; in fig. 3 diagram of the hammer drive.

The forging hammer consists of a two-column bed J in which a slider 2 is placed in the guides, connected by means of two eccentric shafts 3 to the upper vibrating head 4 located below it. The latter are mounted on two supports of the upper striker and are rotated from the drive device. The device consists of an electric motor 5, a gear, a transmission 6 and two articulated shafts 7, each of which is pivotally connected to a corresponding eccentric shaft.

Lower firing pin 8 is fixed, mounted on the frame /. The slider 2 is hinged by means of the rod 9 and is connected to a pneumatic cylinder W, which is intended for raising and lowering the slider with the upper head.

In the working position, the upper firing head 4 is lowered until it contacts the forged workpiece, which lies on the lower striker 8. The eccentric shafts 5, which are driven by the electric motor 5, impart to the upper striker the necessary vibratory movement, with which the workpiece is shaped.
