Pipe bending device of pipe bending machine

Abstract

The invention discloses a pipe bending device of a pipe bending machine. The pipe bending device comprises a support, a rotating assembly, a pipe bending assembly and a clamping assembly, the rotatingassembly comprises a rotating frame and a power source, the rotating frame is supported on the support, and the power source provides rotating power for the rotating frame. The pipe bending assemblycomprises a pipe bending die and a first clamping block, multiple pipe bending grooves are formed in the surface of the pipe bending die, and the section diameters of the centers of the pipe bending grooves are unequal. The clamping assembly comprises a second clamping block and a driving mechanism, the second clamping block and the first clamping block are arranged correspondingly, the driving mechanism is used for driving the second clamping block to get close to or away from the first clamping block in the vertical direction, the multiple pipe bending grooves are formed in the pipe bendingdie, and the section diameters of the centers of the pipe bending grooves are unequal. During use, the corresponding pipe bending grooves can be selected according to actual requirements to achieve pipe bending machining, the production efficiency is effectively improved, universality of the pipe bending machine is optimized, the replacement frequency of pipe bending dies of different sizes is decreased, and the overall manufacturing cost of the pipe bending machine can also be reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a pipe bending device of a pipe bending machine. Background technique [0002] The heat exchanger is the core component of the refrigeration system. During the production process of the heat exchanger, it is necessary to process copper pipes and other pipe fittings into a long U shape with specified specifications and sizes for the production of the heat exchanger. In the prior art, pipe fittings are generally formed by pipe bending machines. [0003] At present, we can see many different types and structures of pipe benders, such as electric pipe benders, hydraulic pipe benders or manual pipe benders, etc., but the existing pipe benders generally only have one pipe bending die, and each Each pipe bending die can only process one pipe fitting at a time. In addition, each pipe bending die can only correspond to one pipe center distance (also can be understood as the bend radi...
