Abstract

The invention discloses a forging die capable of achieving automatic positioning and cooling. The forging die comprises a male die, a female die and an ejection mechanism. The male die is provided with a first drive device and located over the female die and can stretch into the female die. The ejection mechanism can be inserted in the lower end of the female die in a sliding manner so that an opening in the lower end of the female die can be closed. The forging die further comprises two positioning mechanisms which are symmetrically arranged in the horizontal direction. The positioning mechanisms comprise a positioning rod capable of conducting horizontal feeding in the axial direction, and the positioning rod is provided with second drive devices. The two opposite side walls of the female die are provided with two positioning holes for the positioning rod to penetrate. Runners for cooling water to flow are further arranged on the side walls of the female die; and the two ends of each runner are provided with a water inlet and a water outlet correspondingly, wherein the water inlets and the water outlets communicate with an external water tank. By means of the forging die, a forge piece can be automatically positioned before forging, the die can be automatically cooled after forging, and therefore the forge piece can be accurately and rapidly positioned and discharged without errors.

Description

A kind of forging mold being automatically positioned cooling

Technical field

The present invention relates to forging field, be specifically related to a kind of forging mold being automatically positioned cooling.

Background technology

In prior art, held concurrently by mechanically actuated before carrying out forging and manually estimate positioning heat blank at mould Position in tool, reduces partially material or the probability of batch turning as far as possible, after forging terminates, need by forging from Mould takes out.

Come positioning heat blank position in a mold by the double artificial range estimation of mechanically actuated and mainly have following lacking Point: first: the time is long, closed die forging is also referred to as no-flash die forging, belongs to near-net-shape, requirement during forging Blank shape rationally and can be accurately positioned in impression, when the sectional dimension of blank is much smaller than concave die cavity During sectional dimension, material or the situation of batch turning partially easily occur, is positioned manually and needs repeatable operation to position, flower Time-consuming often exceed a few minutes, it is well known that blank temperature is the highest within the specific limits, and plasticity is the best , resistance of deformation is the lowest, and in long position fixing process, the medium such as blank and air contacts, and blank temperature drops Low, plasticity deteriorates and is formed substantial amounts of oxide skin, if blank cannot be accurately positioned, the lighter causes forging Part defect is even scrapped, severe one mold damage；Second: personal safety can not be guaranteed, during forge hot Blank temperature is up to more than 1000 DEG C, and operative employee is operated for a long time under hot environment, peace easily occurs Full accident.

When being removed from the molds by forging, high temperature blank is longer with the time of contact of mould, die during forging The temperature meeting rapid increase of inner ring, causes mould annealing to such an extent as to the intensity of mould reduces, should at complicated Being easy to aggravate the inefficacy of mould under force environment, mold temperature is too high, easily clings with high-temperature forging, top Going out mechanism and cannot eject forging smoothly, this is accomplished by form removal, production efficiency is greatly reduced, under entrance Before one circulation, mould need to be cooled to certain temperature, and the time of air cooling is slow, and production efficiency is low.

Summary of the invention

For solving above-mentioned technical problem, the goal of the invention of the present invention is to provide a kind of and is automatically positioned cooling Forging mold, can be automatically positioned forging before forging, can automatically cool down mould after forging, Make, it is achieved the accurate positioning of forging is quickly and discharging is errorless.
