Pipe bending machine

The pipe bender has the characteristics of convenient operation, stable performance and good working efficiency. It is an ideal equipment for the vegetable greenhouse manufacturing and processing industry

the pipe bender is powered by a variable-frequency motor, with the output force of the reducer and gear transmission. The bending speed can be arbitrarily adjusted by the speed of variable frequency motor. The bending diameter is adjusted by the servo motor

the pipe bender can bend oval tubes, square tubes, round tubes, zigzag steel and other profiles

features of pipe bender:

1. Good function: it can be used in seedling greenhouse, vegetable planting in cold winter, shading and rainproof in summer, rice seedling acceleration, winter breeding and protection of livestock and poultry, cultivation of flowers, fruit trees, plants, etc., construction of yurts, milk stations, resorts, and production of cold sheds, mushroom sheds, breeding sheds, construction sheds, car storage sheds, warehouses, small workshops Hundreds of products such as activity rooms

2. It can produce many types of greenhouse skeleton products, such as round, rectangular, oval, shaped, plastic plated, solid, hollow and so on. The length, radian, height, span and thickness can be adjusted at will

the deformation degree of the pipe of the pipe bender depends on the value of the relative bending radius r/d and the relative thickness t/d. The smaller the value of r/d and t/d, the greater the deformation degree. In order to determine the forming quality of pipe fittings and control the degree of deformation within the allowable range, the excellent bending forming of pipes depends not only on the mechanical properties and bending methods of materials, but also on the use requirements of pipe fittings

the bending of pipe by pipe bender is the same as that of sheet metal. In the case of pure bending, when the tube with outer diameter D and wall thickness t is bent by the external moment M, the outer tube wall of the neutral layer is subject to tensile stress σ 1. The pipe wall becomes thinner due to the action of; Tensile stress of inner pipe wall of neutral layer σ 1. The pipe wall thickens due to the action of. Moreover, the shape of the cross section changes from circular to approximately oval due to the action of the resultant forces F1 and F2. When the deformation is too large, cracks will appear on the outer pipe wall and wrinkles will appear on the inner pipe wall
