Kind Code:
A1
Abstract:
A bending machine for enabling a copper pipe to have an adjustable bending angle. The bending machine comprises a fixed bottom plate (1), wherein a fixed block (2) is arranged on the right side of the top of the fixed bottom plate, an electric push rod (3) is arranged on the left side of the top of the fixed block, a fixed flat plate (4) is arranged on the top of the fixed block, a movable flat plate (6) is movably arranged, by means of a pin shaft, on the top of the electric push rod, a reinforcing plate (7) is arranged on the top of the movable flat plate, a conveying shaft (8) is arranged on both the top of the reinforcing plate and the top of the fixed flat plate, a supporting table (9) is arranged on the outer walls of the front side and back side of the fixed flat plate, limiting sleeves (10) are evenly arranged on the top of the supporting table, the inner walls of the limiting sleeves are in threaded connection with limiting sleeve rods (11), and the bottoms of the limiting sleeve rods are in threaded connection with a pressing device (12).
