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...

AI Technical Summary

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, which will bring errors to the CNC automatic processing and measurement, and finally reduce the practicability of the machine and the forming accuracy of the steel plate surface;

[0006] 3) It does not have the real-time detection function of the temperature in the steel plate heating zone. If the temperature fluctuates too much, it will affect the forming accuracy of the steel plate surface, and in severe cases, it will affect the mechanical properties of the steel;

[0007] 4) It does not have the marking function, which brings inconvenience to the cutting of the remaining material after steel plate processing;
