[0002] The working speed of the press is slow, the contact time between the high-temperature blank and the mold is long, the temperature of the inner ring of the die will rise rapidly during forging, resulting in the annealing of the mold and the reduction of the strength of the mold, and it is easy to aggravate the failure of the mold in a complex stress environment ;The mold temperature is too high, it is easy to stick to the high temperature forging, and the ejector mechanism cannot eject the forging smoothly, which requires mold removal, which greatly reduces the production efficiency; before entering the next cycle, the mold needs to be cooled to a certain temperature, air cooling The time is slow and the production efficiency is low

Embodiment
[0008] Embodiment: An automatic cooling forging die, including a punch 1, a die and an ejection mechanism 2, the punch 1 is located directly above the die and can extend into the die, and the ejection mechanism 2 can be slidably inserted into the die The lower end of the die and the opening of the lower end of the inner ring 6 are closed. The side wall of the die is provided with a flow channel 3 for the flow of cooling water. Nozzle 5, the die includes an inner ring 6 and an outer ring 7, wherein the outer ring 7 is sleeved on the outside of the inner ring 6, and the inner wall of the outer ring 7 is tightly against the outer wall of the inner ring 6, and the inner wall of the outer ring 7 is A spiral opening groove is formed, and the opening groove and the outer wall of the inner ring 6 form a flow channel 3. After the forging is completed, the punch 1 returns, the ejector mechanism 2 works, and the forging is demoulded. At the same time, the water inlet 4 starts to enter wat...

The invention discloses an automatic cooling forging die, which comprises a male die, a female die and a push-out mechanism, wherein the male die is located right above the female die and capable of inserting into the female die, the push-out mechanism is capable of being inserted into the lower end of the female die in a sliding mode and sealing a lower opening of an inner ring, a flow passage in which cooling water flows is arranged in the side wall of the female die, the two ends of the flow passage are provided with a water inlet and a water outlet which are communicated with an outer water tank. According to the automatic cooling forging die, temperature of the inner ring of the female die can be reduced fast, the service life of the forging die is greatly prolonged, and temperature reduction of the inner ring of the female die enables a forged piece to be pushed out smoothly through the push-out mechanism, a circle of working time is reduced, production efficiency is improved, time for cooling in a water circulation mode is shorter than that for cooling in an air cooling mode, waiting time is reduced for a worker, workload of a pressing machine is enabled to be full, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to a forging die, in particular to an automatic cooling forging die. Background technique [0002] The working speed of the press is slow, the contact time between the high-temperature blank and the mold is long, the temperature of the inner ring of the die will rise rapidly during forging, resulting in the annealing of the mold and the reduction of the strength of the mold, and it is easy to aggravate the failure of the mold in a complex stress environment ;The mold temperature is too high, it is easy to stick to the high temperature forging, and the ejector mechanism cannot eject the forging smoothly, which requires mold removal, which greatly reduces the production efficiency; before entering the next cycle, the mold needs to be cooled to a certain temperature, air cooling The time is slow and the production efficiency is low. Contents of the invention [0003] In order to overcome the above defects, the present invention pr...
