Electric pipe bender with LCD digital display

Brief introduction , The pipe bender is mainly used for bending steel pipes in electric power construction, boilers, bridges, ships, furniture, decoration and so on
It has the advantages of multiple functions, reasonable structure and simple operation Electric pipe bender The portable digital display pipe bender has liquid crystal digital display, which makes it have high working efficiency and accurately turn 1-1 / 4 & ldquo; When the pipe bends 190 degrees, just use the thumb wheel to set the required bending degree
The digital display appears on the screen
Just press the switch to display the actual bending degree until the turning is completed
It has 1800 watt motor and heavy-duty gearbox
Bend speed 3

In the case of pure bending, when the pipe with outer diameter D and wall thickness t is bent under the action of external force moment M, the pipe wall outside the neutral layer is subjected to tensile stress and the pipe wall becomes thinner; The inner pipe wall of the neutral layer is subjected to tensile stress, and the pipe wall becomes thicker
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 The deformation degree of pipe depends on the value of relative bending radius R / D and relative thickness T / D
the smaller the value of R / D and T / D, the greater the deformation degree
In order to keep the forming quality of parts, it must be controlled
