Hammer type forging device

Abstract

The invention relates to a forging device and discloses a hammer type forging device. The hammer type forging device comprises a main shaft, wherein the main shaft is fixedly connected with a heavy hammer; a vertical sliding chute is formed in the lower part of the heavy hammer; a heavy block is connected in the sliding chute in a sliding manner; a concave die is arranged at the lower part of the heavy block; a support lug is arranged on the peripheral surface of the heavy block and is located in a vertical strip-shaped hole of the sliding chute; a first elastic part is connected between the top surface of the support lug and the sliding chute; the main shaft is also fixedly connected with a gear; the gear is meshed with a rack; a fixed sliding chute is formed in the lower part of the rack; a second elastic part is arranged between the rack and the sliding chute; a cam presses against one side, far from the second elastic part, of the rack. Compared with the prior art, the heavy block of the device can transmit the force of the heavy hammer to blanks; the heavy block can dissolve the component of the horizontal force of the heavy hammer and only generate the vertical downward pressure, so that the size of the forged parts is more in line with the standard; the qualified rate of products is increased.

Description

technical field [0001] The invention relates to a hammer forging device. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as as-cast looseness produced in the metal smelting process, optimize the microstructure, and at the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material; For important parts with severe working conditions, forgings are mostly used, except for plates, profiles or weldments that can be rolled with simpler shapes. [0003] There are many types of forging equipment. According to the different operating modes of the working parts, forging equipment can be divided into...

Problems solved by technology

[0004] This kind of forging equipment makes the heavy hammer directly contact with the billet. Because the heavy hammer moves in an arc, it is difficult to ensure that the force of striking the billet is vertically downward every time. Often, the direction of the force of the heavy hammer hitting the billet is oblique. Down, the oblique downward force acts on the billet, which will cause a slight deviation of the struck part of the billet, which will eventually cause a deviation in the overall size of the forged part, resulting in the size of some parts not meeting the standard and reducing the product quality. pass rate
