Abstract

An automatic demolding punching machine comprises a punching machine frame, a mold frame and a programming controller, wherein the mold frame is provided with a male mold, a female mold, a mold frame upper plate, a mold frame lower plate, a suspender and a mold change ejection plate; a demolding mechanism, a receiving mechanism and a mold ejection mechanism are also arranged in the mold frame; the demolding mechanism comprises a demolding plate, demolding pull rods and demolding tension springs; the receiving mechanism comprises a hopper, a rotating arm, a middle shaft, oblique blocks and rotating tension springs; and the mold ejection mechanism comprises arrow plates, a mold ejection plate and an ejector rod. Automatic lubricating oil spray is realized under the control of program, automatic demolding is realized, and a punching finished product automatically enters a feed trough; the mold ejection mechanism enables the female mold to have a certain buffer space, so that the product is prevented from deforming; the mold ejection plate is improved so as to facilitate the mold change operation, the number of operators is reduced, the labor intensity and the energy consumption are reduced, the automatic production of the punching product is realized, and the product quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to an automatic punching machine, in particular to an automatic demoulding punching machine for hot forging parts of valve blanks. Background technique [0002] At present, the forging and pressing forming dies made of valves generally use Hafur dies. The structure of the Hafur mold is that two or more sliders are put together to form a cavity. The initial state of the Hafur mold is that the molding cavity is closed, and the outer diameter of the blank is smaller than the hole of the Hafur mold. To form the stamping blank of the punch, since the outer diameter of the formed product is larger than the hole of the Hafur mold, in order to separate the punch from the product, the slider of the Hafur mold must be lifted to realize the side parting of the Hafur mold. After taking out the product, make the Hafur mold The mold cavity is closed and homing. The above forging and forming operation steps are all done manually, which is labo...
