Description

Technical Field

[0002] The serpentine tube bender is a device that uses a hydraulic system to control and achieve bending through a die-changing head. Its basic working principle is: put the metal material into the bender, push the rotating structure equipped with the die-changing head so that the die-changing head contacts one end of the metal material, and then continuously push the die-changing head to complete the metal bending process. The serpentine tube bender can quickly complete the bending of metal tubes. One machine can complete the processing of multiple tube diameters at the same time, effectively improving production efficiency. The serpentine tube bender can complete the bending of metal tubes through digital control, which greatly guarantees the processing accuracy and consistency. The common serpentine tube bender on the market also has the following disadvantages;

[0003] First, during the pipe bending process, the bending length is uncontrollable or the accuracy is low, which affects the bending efficiency and results in a large number of unqualified workpieces.

[0004] Second, some raw materials will be deformed or bent after bending, and need to be reshaped before use. Sometimes secondary processing is required after bending the pipe. Utility Model Content

After the length is determined, tighten the control lever to limit and fix the mobile component. During the pipe bending process, after the raw material is transported, it contacts the buffer plate component. The buffer plate component compresses the spring to eliminate the impact force. At the same time, the buffer plate component uses elastic reset to control the raw material to bend at an appropriate length to ensure the bending length and accuracy.

[0017] 2. Before bending the pipe, the raw material first passes through the inside of the high-frequency heating element to heat the raw material, and then passes through the inside of the shaping hole.

Then the raw material passes through the auxiliary parts to ensure that the raw material is bent in a long straight state, so that the serpentine tube can be bent into shape at one time without the need for early or later shaping.
