A bending device for thin-diameter thin-walled metal pipes

Abstract

The invention discloses a bending device for small-diameter and thin-walled metal pipes. The bending device comprises a frame. One end of the frame is provided with a clamping mechanism, and the other end is provided with a bending mechanism. The bending mechanism includes a first motor and a The first gear is sleeved on the first motor, the first gear is meshed with the second gear, the center of the second gear is provided with a first positioning shaft, the bottom of the first positioning shaft is fixed on the base plate, and the base plate is installed on the frame The upper end face of the first positioning shaft is fixed with a fixed wheel, the large gear is provided with a second positioning shaft that is not coaxial with the first positioning shaft, and the upper end face of the second positioning shaft is fixed with a bending wheel, a fixed wheel and a bending wheel There is a matching gap for accommodating thin-walled metal pipes with small diameters. The invention bends the pipe material to a preset angle through the bending mechanism, has little influence on the deformation of the pipe material during the bending process, the transition of the bending part is smooth, the degree of automation is high, and the processing precision is high, and it can be widely used in small diameters of different specifications. Bending of thin-walled metal pipes.

Description

technical field [0001] The invention belongs to the technical field of bending and processing of small-diameter and thin-walled metal pipes, and in particular relates to a bending device for small-diameter and thin-walled metal pipes. Background technique [0002] Among the many heat transfer elements, the radiator pipe is one of the most effective heat transfer elements known to people. It can transmit a large amount of heat through its small cross-sectional area and long-distance transmission without external power. At present, the radiator pipe has been widely used. In many engineering fields such as petroleum, chemical industry, power, metallurgy, aviation, automotive biology, electronics, etc., many equipment will generate heat to varying degrees during operation, so that the temperature of the equipment will rise, and a good cooling system must be provided, and the radiator is this system. core components.

Problems solved by technology

The bending device clamps one end of the thin-diameter thin-walled metal pipe to be processed through the clamping mechanism, and sends the other end into the matching gap between the fixed wheel and the bending wheel, and controls the bending wheel to surround the fixed wheel through the first motor. Turn to realize the bending operation of thin-diameter and thin-walled metal pipes. During the bending process, the influence on the deformation of the pipe is small, the transition of the bending part is smooth, the processing accuracy is high, and the degree of automation is high, which effectively solves the structure of the existing metal pipe processing device. Complicated, low degree of automation, low machining accuracy, low efficiency and unsuitable for mass production
