Casting machine and casting method for liquid forging

Abstract

The invention discloses a casting machine and casting method for liquid forging and belongs to the technical field of special forging techniques and equipment. The casting machine comprises a machine base, a rotating mechanism, a lifting mechanism, a telescopic mechanism, a flow guiding system, a hydraulic system and a control system. The flow guiding system is connected to the telescopic mechanism. The telescopic mechanism is installed on the rotating mechanism. The rotating mechanism is fixed to the lifting mechanism. The lifting mechanism is installed on the machine base. The hydraulic system is used for driving to achieve rotational movement, rising and falling movement and stretching and retracting movement. Casting outside the machine is achieved through the steps of adjusting a casting position, preheating a flow guiding groove, rotating the flow guiding groove to the casting position, conducting casting, and restoring the flow guiding groove, and the manufacturing cost and the use cost of a liquid forging machine can be remarkably reduced. The casting machine and casting method can be used for liquid forging of large pieces and rapid and stable casting, can decrease the defective rate and is wide in application range.

Description

technical field [0001] The invention relates to liquid die forging, in particular to a pouring machine and a pouring method for liquid die forging. It belongs to the technical field of special forging technology and equipment. Background technique [0002] Liquid die forging is an advanced material forming technology, which has been used to form various material parts. The traditional pouring method of liquid die forging is to extend the ladle into the liquid forging machine for pouring, which causes the opening of the liquid forging machine to increase by at least 500mm. For large parts, the opening of the liquid forging machine will increase more. The cost has also been greatly reduced. Not only that, in this pouring method, the high-temperature molten metal is exposed to the air for a long time, which will cause secondary pollution such as oxidation and air absorption, which will affect the quality and performance of the workpiece. [0003] When liquid die forging larg...

AI Technical Summary

Problems solved by technology

In the prior art, the method of pouring the casting ladle into the liquid forging machine can only be used for small pieces, not for large pieces of liquid forging

When the weight of the workpiece is greater than 20kg, a special mechanism is required to make the ladle enter the liquid forging machine smoothly and quickly. After the quantitative and controllable pouring is completed, the ladle and these mechanisms must leave the liquid forging machine quickly, otherwise there will be waste or defective products. products, there is no pouring method and equipment that can meet these requirements in the prior art
