Classification of pyrotechnics

Pyrotechnics are divided into two types: inner and outer fields. The outer field mainly corrects hull segments and hull components, and the inner field mainly corrects the curvature of the hull outer plates. Basically, they are water-fire bending plates.

Water-fire bending plate

refers to the local linear heating of the plate with an oxygen-acetylene torch along a predetermined heating line, and followed by water cooling (or allowing it to cool naturally), so that A plate bending method that produces local plastic deformation of the plate, thereby bending the plate into the required curved surface shape. In some countries, it is called linear heating method. Water-fired plate bending is currently the main process method used by most ship manufacturing, steel structure and other heavy industry enterprises to bend complex curvature plates and large internal components of the hull.

The types of pyrotechnic correction can be divided into:

1, lines

2, dots

3, strips

4, Horseshoe

Position requirements 1. According to the line requirements of the sample and sample box, operate the hydraulic press and the pyrotechnics faucet, and perform the outer panels of the head, tail and other parts according to the requirements of the operating standards. Cut parts with linear or complex linear shapes are subjected to thermal processing to ensure that the linear shape of the parts meets the design and quality requirements. 2. Carry out daily maintenance of the equipment according to the maintenance manual of the hydraulic press, and cooperate with maintenance personnel to perform repairs, secondary maintenance and repairs on the equipment. Recruitment requirements: technical secondary school degree, hull, pyrotechnics and other related majors; familiar with hull lines, hull lofting, familiar with the operation of pyrotechnics processing equipment, possessing an open flame operation certificate, a lifting hook certificate, and more than three years of independent pyrotechnics operating experience< /p>
