Double rotary automatic pipe bending mechanism

Abstract

The present invention belongs to the field of mechanical and control technology, and is especially an automatic double rotating pipe bending mechanism. The automatic double rotating pipe bending mechanism includes two motors, two gear drive mechanisms, two rotary tables, two sets of thrust bearings, one fixing bearing, one fixed table, two fixed cylinders, four rotatable cylinders, and one motor bearing board. After the straight pipe work piece is set in the pipe mold, force is applied for continuous bending. The present invention has simple structure, low cost, capacity of bending pipe continuously, high production efficiency and other advantages, and may be used in large scale production of evaporator and condensator.

Description

technical field [0001] The invention relates to an automatic pipe bending mechanism, in particular to a double-rotation automatic pipe bending mechanism used on the automatic processing production line of a fin evaporator. It belongs to the field of machinery and control technology. Background technique [0002] For the evaporator or condenser of refrigeration equipment such as refrigerators and air conditioners, in order to make the same product volume have the largest heat exchange area, finned evaporators or finned condensers are basically used. Its production and processing process includes more than a dozen processes, such as fin stamping, fin insertion, pipe threading, pipe expansion, pipe bending, internal cleaning and other processes. At present, the largest evaporator and condenser manufacturers in China are still traditional manual operations, with low production efficiency and far from meeting the requirements of large-scale production. There is an urgent need to...

Problems solved by technology

In the existing technology, the existing pipe bending machines at home and abroad are mainly divided into three types, one is a general pipe bending machine, such as the SXS-38 automatic hydraulic double-head pipe bending machine, this pipe bending machine generally adopts PLC (can be Programmable controller) control, you can choose one or more than two operations at a time according to the size of different material pipe diameters, but the disadvantage is that it is expensive and cannot bend straight pipes for multiple times continuously, and the bending efficiency is not high

The second type is WYQ electric pipe bending machine. The high-pressure oil output by the electric oil pump is sent into the working oil cylinder through the high-pressure oil pipe. The machine is manually controlled, easy to operate, and the price is reasonable, but it also cannot realize continuous multiple bending of straight tube workpieces, so it is of little help to improve the automation of the finned evaporator processing production line.

However, this machine is mainly used to complete the one-time bending of multiple U-shaped pipes at the same time, and it cannot achieve continuous multiple bending.
