Special adjustable support for tooling steel plate forming of aviation composite material and forming method thereof

Abstract

The invention relates to a special adjustable support for forming a steel plate of an aeronautical composite tooling. A trapezoidal threaded support part is in threaded connection with the inner hole of a positioning support base, and a lock nut is arranged on the outer circumference of the trapezoidal threaded support part and is seated on the upper surface of the positioning support base; a spring is arranged in the cavity in the upper end of the trapezoidal threaded support part and supports a ball head jacking rod, a self-lubricating lead ring is arranged on the outer circumference of the ball head jacking rod, and an extension rod extending into the spring is arranged at the lower end of the ball head jacking rod; the upper end of the ball head jacking rod is a semi-spherical surface, and the upper end of the trapezoidal threaded support part is also a semi-spherical surface. The adjustable support is adjustable in height, can effectively reduce the production cost of the large-scale composite tooling and obviously shorten the tooling manufacture period when in use, improves the forming precision and greatly lowers the working and production costs.

Description

technical field [0001] The invention relates to a special adjustable support and a forming method for forming an aviation composite material tooling steel plate, which is used for forming the integral steel plate used in the aviation composite material tooling, and belongs to the field of mechanical manufacturing. Background technique [0002] In the field of manufacturing aviation composite material tooling, in order to ensure the airtightness of such tooling during use, it is required that the formed steel plate used for the tooling must be an integral metal plate. At present, in the metal plate forming process, the carcass formed by supporting the steel plate is generally supported by a wooden support tire. This kind of wooden tire is expensive to manufacture and has a long manufacturing period. It is easily affected by factors such as temperature, humidity and force during use. The cracking and deformation reduces the forming accuracy of the steel plate, and the wooden s...

At present, in the metal plate forming process, the carcass formed by supporting the steel plate is generally supported by a wooden support tire. This kind of wooden tire is expensive to manufacture and has a long manufacturing period. It is easily affected by factors such as temperature, humidity and force during use. The cracking and deformation reduces the forming accuracy of the steel plate, and the wooden support tires still have great fire safety hazards, and the wooden support tires are seriously damaged after use, and their turnover and destruction are very difficult, which virtually improves the production of tooling cost
