Hebei pipe bender manufacturers on the pipe bender simple introduction

Technical parameters of bending pipe: the raw steel pipe used for bending pipe of this equipment is seamless steel pipe, straight seam steel pipe or spiral welded pipe.The bending radius of the elbow must be greater than 2.5D, and the bending radius below 2.5D shall be manufactured by elbow pushing process.Programmable intelligent control of bend Angle, bend Angle in a certain range according to the needs of arbitrary setting.Push the elbow diameter and wall thickness range, diameter 89-1420mm wall thickness 5-120mm segment design and manufacture the equipment.The stroke of the main cylinder is determined according to the maximum diameter of the elbow and the maximum bending radius. The above is provided by the user.

The pipe bender is a special non-standard equipment for the production and manufacture of all kinds of bending steel tubes with equal diameter, especially those with larger diameter. It can continuously produce the bending steel tubes with multiple sections and multiple radius of curvature and the bending pipe for short.The technical indexes such as the diameter and wall thickness of the elbow and the range of curvature radius are proposed by the user, and the equipment manufacturer designs and manufactures the equipment according to the user's requirements.

This series of elbow machine is mainly used for carbon steel, stainless steel 1D\1.5D elbow cold push molding is also used for seamless steel pipe push made elbow special equipment, can be customized according to user requirements.Mid. Small hydraulic push bending molding machine.

Bender base track: main cylinder and support plate, elbow clamping wheel device, elbow rocker arm, rocker arm rail, rocker arm shaft, elbow combination chuck, intermediate frequency transformer adjustment device, intermediate frequency transformer, intermediate frequency power supply.Intelligent control system, operating platform and touch screen film, cooling water circulation system, etc.

The design of the pipe bender and the calculation of the force of the pipe are based on the knowledge of the textbook of "elastic-plastic mechanics".

This is a torque equilibrium equation, the one on the left is the external force torque, the one on the right is the internal force torque, and it is equal to the integral over the whole section of the torque generated by the stress on the neutral axis.When bending, the axis of the pipe is the central axis.

If the outer diameter of the pipe is D, the inner diameter is D, and the yield limit is OS, the bending deformation is carried out on the mold with the curvature radius of R, therefore, the inner ring radius of the pipe is R.If the distance between the bending deformation point and the force applied point is L and the material is not hardened, then the whole clean surface will enter the plastic state when the bending deformation occurs.Reason: L = 2 P * * Integral {2 * * DY * OS x * y 0, D / 2} - 2 * Integral {2 * * DY * OS x * y 0, D / 2} = {} ^ 3 D ^ 3 - D * OS / 6 P = {} ^ 3 D ^ 3 - D * OS / * L [6] this is the material of the size of the bend stress hardening.
