Problems solved by technology

However, metal cooling is still in an uncontrollable state. If the internal cooling occurs first and the external molten metal is not filled in time, quality problems such as shrinkage porosity and pores will appear in the casting, which will seriously affect the mechanical properties of the casting.

Abstract

The invention discloses a propeller casting forming solidification sequence control device and a control step thereof, and relates to a propeller casting machining device and step, in particular to aforming sequence solidification device and a control step thereof. The control device comprises a sand mold, a propeller blade part control system, a blade root part control system and a propeller hubpart control system; the propeller blade part control system, the blade root part control system and the propeller hub part control system are sequentially arranged from the propeller sand mould blade part to the propeller hub part. The device has the beneficial effects that the structure is novel, machining is easy and convenient, use is convenient, work efficiency is improved, product quality is improved, and cost is reduced; the novel propeller casting forming solidification sequence control device and the control step therefore are integrated with economy and practicability.

Description

technical field [0001] The forming and solidifying sequence control device for propeller castings and the control steps thereof according to the present invention relate to a processing device and steps for propeller castings, specifically a forming sequence solidification device and control steps thereof. Background technique [0002] With the development of science and technology, the requirements for the precision of casting products and the performance of castings are getting higher and higher. Therefore, it is necessary to improve the efficiency of casting work, accelerate the cooling speed of castings, promote the refinement of casting grains, and improve the mechanical properties of castings. The material of the propeller is usually nickel-aluminum bronze. For this alloy with a large volume shrinkage rate, the control of the solidification sequence and solidification speed is a key factor affecting the quality of the casting. [0003] The existing pouring molding meth...
