Product Description
Suitable for the production of seamless 89mm diameter and welding elbow forming cold bending machine
1.Product Presentation
The cold push elbow machine can bend the pipe as well as the sheet metal.In the case of pure bending, when the pipe with external diameter D and wall thickness t is bent under the action of external torque M, the outer wall of the neutral layer is subjected to tensile stress 1 and the pipe wall becomes thinner.The inner tube wall of the neutral layer thickens under the action of tensile stress 1.Moreover, the shape of the cross section changes from a circle to an approximate ellipse due to the action of the resultant force F1 and F2. When the deformation amount is too large, cracks will occur on the outer tube wall, while wrinkles will occur on the inner tube wall.
The degree of tube deformation depends on the relative bending radius R/D and relative thickness t/D values.The smaller R/D and t/D, the greater the deformation.In order to ensure the forming quality of pipe fittings, it is necessary to control the deformation degree within the permitted scope.The forming limit of pipe fitting shall include the following contents:
1) the maximum elongation deformation in the tensile deformation zone outside the neutral layer does not exceed the plastic allowable value of the material, resulting in fracture;
2) in the compression deformation zone inside the neutral layer, the thin-walled structure under the action of tangential compressive stress will not be more than unstable and wrinkle;
3) if the pipe fitting is required to be ovality, control its section to produce distortion;
4) if the pipe fitting is required to bear the strength of internal pressure, control the forming limit of wall thickness reduction.

Use method of cold push pipe bender:
1. Usage:
(1) refer to the operating instructions of the electric oil pump.
(2) first screw the working oil cylinder into the internal thread of the square block, so that the wheel mounted on the bracket at the rear end of the oil cylinder is downward.
(3), choose according to bend the pipe by the outer diameter of the die set in column fortress, two roller groove which corresponds to die, and then in the corresponding size of the plate hole, then the cover plate, the curved pipe inserted into the slot, then quick joint activities of high pressure oil pipe end part of the back and set on the joint of working cylinder, electric oil pump on the oil drain screw tightening, can bend.After bending the pipe, loosen the oil drain screw and the plunger will reset automatically.
2. Precautions:
(1) refer to the operating instructions of the electric oil pump.
(2) do not unload the quick connection when there is load.
(3) the machine and tools is oil as the medium, must do a good job of oil and the machine and maintenance work, so as to avoid blockage or oil leakage, affect the use effect.
