A low-pressure casting bearing conversion device for large-scale castings and its manufacturing method

Abstract

The invention discloses a heavy casting piece low-pressure casting bearing switching device and a manufacturing method thereof. The heavy casting piece low-pressure casting bearing switching device comprises a bracket, tapered iron and sensors, the bracket is installed on the ground through the tapered iron, and the sensors used for measuring the load of bearing force are arranged between the bracket and the tapered iron. According to the heavy casting piece low-pressure casting bearing switching device and the manufacturing method thereof, a furnace body is installed in the bracket, so that the load borne by the furnace body is effectively dispersed, and the problem that the bearing force of traditional small and medium casting equipment is low is solved; and the bracket, the tapered iron and the sensors cooperate with one another, the extent of contact between the bracket and a table top is flexibly adjusted, and the problem that the traditional small and medium casting equipment is poor in airtight performance is solved.

Description

technical field [0001] The invention relates to a low-pressure casting bearing conversion device for large-scale castings and a manufacturing method thereof, which is especially suitable for low-pressure casting of a medium-sized casting furnace, and belongs to the technical field of metal technology and casting engineering. Background technique [0002] With the development of thin-walled complex castings in the direction of "lightweight" and "precision", the demand for complex thin-walled castings in modern aviation, aerospace and other fields is becoming more and more obvious. Complex, large outline size, high dimensional accuracy, high internal quality requirements. The casting technology of large and complex thin-walled parts has become one of the key technologies for national defense modernization. At present, low-pressure casting has been widely used in the field of casting. It is a commonly used precision molding method and is also suitable for the production of larg...

Problems solved by technology

However, in the initial stage, enterprises still focus on the production of small and medium-sized castings for profit. Large and super-large castings can only be used as trial products, and the batches are small. If new supporting casting equipment is purchased, the utilization rate will be low, resulting in a large backlog of costs; With existing equipment, the furnace body cannot reach the carrying capacity of large castings
