Bending machine for ship manufacturing

Abstract

The invention relates to the technical field of ship manufacturing, and discloses a bending machine for ship manufacturing. The bending machine comprises a bottom frame, two support piers and two rotating parts, a pressure applying rod is arranged at one end of each rotating part, a lower pulley block is arranged at the other end of each rotating part, a door-shaped frame is arranged on the bottom frame, and an upper pulley block is arranged at the bottom of a top frame of the door-shaped frame. the bending machine further comprises a tension rope and a traction assembly, one end of the tension rope is connected with the door-shaped frame, the middle of the tension rope is wound around the upper pulley block and the lower pulley block, the other end of the tension rope is wound around the traction assembly, pressure applying pieces are arranged at the bottoms of the two pressure applying rods, and a piece placing table is arranged below the pressure applying pieces. According to the bending machine, the rotating parts, the pressure applying rod, the pressure applying pieces, the upper pulley block, the lower pulley block, the tension rope and the like are arranged, the lever principle and the pulley blocks are comprehensively applied, large bending force can be obtained with small applied force, the bending requirement of steel plates used in ship manufacturing is met, the cost is far lower than that of the bending machine for applying the same bending force in the market, and the equipment investment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a bending machine for shipbuilding. Background technique [0002] In shipbuilding, it is first necessary to build the hull, which is composed of multiple steel plates, and not all of the steel plates used are flat plates. According to the position of the steel plates in the hull, steel plates with broken lines, arcs or other shapes are often required, so the steel plates need to be processed Corresponding bending treatment, so the bending treatment of the steel plate is an essential basic work for building the hull. However, based on the high quality requirements of the ship's own strength, pressure resistance and other technical indicators, its hull often uses relatively strong steel plates. Therefore, the bending force required for bending such steel plates is about several hundred tons, while the market The cost of bending equipment that meets the above-mentioned bending...

Problems solved by technology

However, based on the high quality requirements of the ship's own strength, pressure resistance and other technical indicators, its hull often uses relatively strong steel plates. Therefore, the bending force required for bending such steel plates is about several hundred tons, while the market The cost of bending equipment that meets the above-mentioned bending force requirements is relatively high, often hundreds of thousands or even millions, which is a large capital investment for shipbuilding enterprises
