Problems solved by technology

[0004] 1) Oxyacetylene flame heating is used, the controllability and reproducibility are poor, the work efficiency is low, and the pollution to the working environment is relatively large;
[0005] 2) In the process of deformation of the curved surface of the steel plate, the equipment under test and research in China does not consider the automatic support and positioning of the steel plate, and uses manual methods to adjust the support with wooden wedges
It is cumbersome and troublesome to implement. If the steel plate cannot be padded in time, it is easy to cause the position of the steel plate to change...

Abstract

The invention relates to a thermal stress curve forming machine for a numerical control plate. The thermal stress curve forming machine is characterized in that a heating device consists of a high-frequency induction power source, a heating head connected with an elevating mechanism, and a cooling water circulating apparatus; a polygonal or annular induction coil is arranged in the heating head, an electromagnetic valve and a water jet are arranged on the high-frequency induction heating head, a universal roller is arranged at the bottom of the high-frequency induction heating head; a detection device is composed of a laser distance sensor, a height detection rod and an infrared temperature sensor; a measuring seat connected with a lifting rod is provided with the laser distance sensor and the height detection rod, the infrared temperature sensor is arranged on the heating head, a supporting mechanism consists of at least 6 active supports and 8 driven supports. The thermal stress curve forming device for the numerical control plate can greatly improve production efficiency, shorten shipbuilding period, and improve measuring accuracy and shipbuilding quality, and can lower shipbuilding cost.

Description

technical field [0001] The present invention is a kind of equipment for forming the curved surface of steel plate, especially a kind of numerical control equipment which produces the required deformation by heating and cooling the surface of steel plate, and especially relates to the mechanical structure of the curved surface forming machine, which can be automatically completed by using this equipment Steel plate surface forming processing. Background technique [0002] One of the key and important links in shipbuilding is the forming process of the hull surface. The curved surface of the hull is very complex, especially the bow and stern, the size and shape of the outer plate are changeable, and the processing is difficult. At present, most shipyards at home and abroad mainly use oxygen-acetylene flame to move locally on the surface of the steel plate to heat and track water cooling when forming the curved surface of the ship plate, commonly known as water and fire bendin...
