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

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] This embodiment provides technical details of a pouring machine for pouring 50-250kg of aluminum alloy, carbon steel or high-chromium cast iron for liquid die forging on liquid die forging machines of different tonnage specifications.

[0049] The crane scale is used to weigh and quantify the ladle and the metal melt in it, and then pour the metal melt of the required weight into the flow guide tube of the pouring machine outside the liquid die forging machine, and the metal melt flows along the flow guide tube , and flow into the mold cavity through the outlet at the front end of the draft tube. After the pouring is completed, the guide tube rotates quickly and leaves the liquid forging machine, and the liquid forging machine can quickly close the mold to realize the liquid forging of the workpiece.

Abstract

A pouring machine for liquid die forging and a pouring method. The pouring machine includes a machine base, a rotating mechanism, a lifting mechanism, a telescopic mechanism, a diversion system, a hydraulic system and a control system; the diversion system is connected to the telescopic mechanism, and the telescopic mechanism is installed on the rotating In terms of mechanism, the rotating mechanism is fixed on the lifting mechanism, the lifting mechanism is installed on the base, and the hydraulic system drives the rotation, lifting and telescopic movements. And through the steps of adjusting the pouring position, preheating the guiding groove, rotating the guiding groove to the pouring position, pouring, and resetting the guiding groove, the external pouring is realized, which can significantly reduce the cost of liquid forging and the use of the machine. It is a device and method that can be used for liquid forging of large pieces, rapid and stable pouring, and reduction of defective rate, and has a wide range of applications. It belongs to the technical field of special forging process and equipment.

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...
