The invention discloses a fully-automatic pipe expander which comprises a stand, wherein a rotating disk capable of rotating on the stand is also arranged on the stand; a fixing component capable of fixing the lower end of a pipe fitting of a heat exchanger is arranged on the rotating disk; and a flaring mechanism capable of flaring the pipe fitting of the heat exchanger and a pipe expanding mechanism capable of expanding the pipe fitting of the heat exchanger are also arranged on the stand. In the invention, the rotating disk capable of rotating is arranged on the stand, the flaring mechanism capable of flaring the pipe fitting of the heat exchanger and the pipe expanding mechanism capable of expanding the pipe fitting of the heat exchanger are also arranged on the stand, and the rotating disk is rotated after flaring for pipe expanding so that the operation of flaring and pipe expanding can be realized on one machine, thereby saving the working procedure and enabling operation and control to be simple and convenient; and a servo motor and a chain-chain wheel group are used for carrying out transmission, thereby greatly improving the accuracy.
Description
【Technical field】 [0001] The invention relates to a fully automatic tube expander. 【Background technique】 [0002] The tube expander is the key equipment of an important part in the heating exchanger air conditioner. Its principle is: use an expansion rod to set an expansion ball larger than the diameter of the copper tube on its end face. Under the action of external force, the expansion ball squeezes the copper tube, expands the copper tube, and makes it closely contact with the heat sink to avoid loosening. At present, the tube expanders on the market have the following defects: 1. The precision of flaring and tube expansion is difficult to control, and the product quality is difficult to guarantee; 2. The process is complicated and complicated, and the production time is long, which increases labor and increases manufacturing costs; 3. Operation and control are complicated, which is not conducive to production. 【Content of invention】 [0003] The object of the presen...
