Description

Material lifting device on hot die forging press

Technical Field

The utility model relates to a forge technical field, concretely relates to ejecting device on hot die forging press.

Background

At present, after the forging of a hot die forging press is finished, a sliding block returns, and at the moment, a forging and the sliding block are separated by an upper ejection device. At present, an upper ejection device of a hot die forging press generally adopts a mechanical cam type upper ejection device, and the principle of the mechanical cam type upper ejection device is that a connecting rod swings left and right to drive a cam to rotate so as to realize downward movement of an ejection beam (carrying pole beam) and drive an ejection rod to move downward, so that a forged piece adhered to the lower surface of a sliding block is ejected. In the long-term use process, the continuous friction between the cam and the ejection beam causes the abrasion of the cam and the ejection beam, thereby greatly reducing the precision during ejection, even failing to realize the ejection function, possibly causing the blank car or damaging the mould, improving the cost and reducing the production efficiency.

Patent document No.202123378404.9 discloses an upper and lower liftout device of hot die forging press, and its technical scheme main points are: the die comprises a base, wherein a lower die cavity is formed in the top surface of the base, and mounting grooves are formed in the four corners of the top surface of the base respectively; the supporting column is arranged inside the mounting groove, a movable plate is sleeved on the outer circular wall surface of the supporting column, and an upper die is arranged on the bottom surface of the movable plate; the upper and lower ejection components are arranged inside the lower die cavity and used for ejecting materials, each upper and lower ejection component comprises an upper ejection groove, each upper ejection groove is formed in the inner bottom surface of the lower die cavity, each lower ejection groove is formed in the bottom surface of the upper die, ejector rods are movably sleeved inside the upper ejection groove and the lower ejection groove, one end of each ejector rod is provided with a limiting block, one side of each limiting block is provided with a reset spring, the ejector rods are pushed to move inwards by pushing the ejector rods to compress the reset springs, the ejector rods are pushed to move upwards by the reaction force of the reset springs at the moment to push out the dies, the ejector rods arranged on the bottom surfaces of the upper dies move downwards, the dies are prevented from being adhered to the surfaces of the upper dies, and the working efficiency is improved; the disadvantages are that: when the hot die forging press works, the ejector rod is in direct contact with a hot material, the defects of galling and abrasion are easily caused after long-time use, frequent replacement and maintenance are needed, the ejector rod of the ejector device and the limiting block are arranged in the upper ejection slot and the lower ejection slot, and the ejector rod is inconvenient to replace when damaged.
