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

Embodiment 1

[0072] The maximum bearing weight of the existing furnace body in a workshop is 3t, which is suitable for casting small and medium-sized castings. Now it has received a research and development task for a large cabin. After calculation, the maximum pressure on the furnace body will be as high as 4.5t when pouring this casting. There is a furnace body that cannot be poured.

[0073] According to the size of the casting furnace body and crucible in the workshop, the specific parameters of the support are determined as follows:

[0074] The distance L1 between two load-bearing beams 101=1200mm;

[0075] The overall height of the load-bearing device H1 = 500mm;

[0076] The distance L2 between the two support beams 102=1600mm;

[0077] The profiles that meet the conditions are determined by comparing the above parameters with the list of profiles. Since I-beams, H-beams and square steels do not satisfy H<100mm, the profile 8# channel steel is selected as the production material....

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 large-scale low-pressure casting load-bearing conversion device and a manufacturing method thereof, which is especially suitable for low-pressure pouring of medium-sized casting furnaces, 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. These complex thin-walled parts have thin walls, structures Complexity, large outline size, high dimensional accuracy, and high internal quality requirements. The casting technology of large and complex thin-walled parts has become one of the key technologies for the modernization of national defense. At present, low-pressure casting has been widely used in the field of casting. It is a commonly used precisi...
