Abstract
The invention relates to an upsetting-connecting forming mold for an air conditioner pipe and an end face sealing pressing plate. The upsetting-connecting forming mold comprises a clamping mold, a first station pipe-expanding mold, a second station pipe-contracting mold, a third station pipe-contracting mold, a fourth station step-forming mold and a fifth station hole-expanding mold. The pipe diameter of the end of the air conditioner pipe is expanded through the first station pipe-expanding mold. A short section of the end of the air conditioner pipe subjected to pipe expanding through the first station pipe-expanding mold is subjected to pipe contracting through the second station pipe-contracting mold and the third station pipe-contracting mold. The pipe wall of the air conditioner pipe is made to be in a step shape through the fourth station step-forming mold. Hole expanding is conducted through the fifth station hole-expanding mold. The end face sealing pressing plate is subjected to upsetting-connecting forming through the upsetting-connecting forming mold, and all quality problems caused by the brazing process can be avoided. Compared with upsetting-connecting forming of a radial sealing pressing plate, hole expanding is conducted through the fifth station hole-expanding mold, the spiral groove process is cancelled, the process routes are reduced, and the turnover efficiency is improved.
