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.

Before the use of the cold push elbow machine to check whether the power switch is normal, hydraulic oil is not prepared enough.Check whether there is any damage to the press mould and whether the height meets the requirements.Check whether the press mold is installed in place and should be fixed firmly.Adjust the Angle positioning frame to the appropriate position, put the electric heat neatly in the die to start the bending machine to make sure that the Angle of the bend is in place before taking it out and replacing it with the other end to repeat the above actions.Mark the processed products.The equipment must be carefully checked that there is no product or foreign body in the die before starting.After the device is opened, it is strictly forbidden to put your hand into the die or the rod stroke.In the production process, if there is an abnormal situation, the power should be cut off first to confirm the shutdown and then check.After production, the power switch should be turned off and the site cleaned.
