Abstract
The invention relates to a piston electron beam welding and vacuumizing method. A vacuum box is arranged at the side edge of a vacuum chamber, a sealing door is arranged between the vacuum box and the vacuum chamber, and the vacuum box is provided with a second vacuum pump. When a machine is started for first welding, after a piston fixture enters the vacuum chamber, the vacuum chamber is sealed, the sealing door is closed, the vacuum chamber is vacuumized by a first vacuum pump, then a piston is welded, and simultaneously the vacuum box is vacuumized by the second vacuum pump. After the piston is welded and replaced, the vacuum chamber is sealed after the piston fixture enters the vacuum chamber again, and the sealing door is opened at this time to make the vacuum chamber communicated with the vacuum box. Because the vacuum box is in a vacuum state and the size of the vacuum box is many times larger than that of the vacuum chamber, the vacuum box and the vacuum chamber both approach to the vacuum state, then the sealing door is closed, the vacuum chamber is vacuumized by the first vacuum pump so as to make the vacuum chamber quickly enter the vacuum state for welding the piston, and then the operation is cycled repeatedly.
Description
Technical field
The present invention relates to the welding field of the piston of compressor of air conditioner, especially a kind of piston electron beam welding vacuum pumping method.
Background technology
Electron beam welding is all adopted in welding to the piston of compressor of air conditioner in the industry, and the condition of electron beam welding is relatively harsher, need under the environment of vacuum, carry out.And existing equipment has only vacuum chamber, and behind each replacing piston, the air pressure of internal vacuum chamber is consistent with atmospheric pressure; Need seal vacuum chamber, vacuumize with vavuum pump again, need to use vavuum pump to vacuumize behind so each replacing piston; Need to wait for the long period; Thereby reduced the efficient of welding, also reduced the utilization rate of welding equipment, increased the processing cost of piston welding.
Summary of the invention
The objective of the invention is provides a kind of piston electron beam welding vacuum pumping method that can reduce the pumpdown time of vacuum chamber for the deficiency that solves above-mentioned technology.
In order to achieve the above object; The piston electron beam welding vacuum pumping method that the present invention designed is provided with vacuum tank at the vacuum chamber side, and the vacuum tank volume is the several times of vacuum chamber volume; Be provided with hermatic door between vacuum tank and the vacuum chamber, vacuum tank is provided with second vavuum pump; When start is welded first, after the piston anchor clamps get into vacuum chamber, the vacuum chamber sealing, hermatic door is closed; Utilize first vavuum pump that vacuum chamber is vacuumized, piston is welded again, at the same time, second vavuum pump vacuumizes vacuum tank; Accomplish Deng the piston welding, behind the replacing piston, after the piston anchor clamps get into vacuum chamber once more, the vacuum chamber sealing; Internal vacuum chamber air pressure is consistent with atmospheric pressure, and open hermatic door this moment, and vacuum chamber is communicated with vacuum tank; Air pressure maintains an equal level rapidly, and since before this vacuum tank be in vacuum state, the vacuum tank volume is the several times of vacuum chamber volume simultaneously; So the both near vacuum state, closes hermatic door again, re-use first vavuum pump vacuum chamber is vacuumized; Use second vavuum pump that vacuum tank is vacuumized, piston is welded repetitive cycling work after this after making vacuum chamber get into vacuum state fast.
The resulting piston electron beam welding of the present invention vacuum pumping method a vacuum tank is set in the vacuum chamber side, and the volume of vacuum tank is greater than the volume of vacuum chamber; When vacuum is indoor when piston is carried out welding processing, second vavuum pump on the vacuum tank vacuumizes vacuum tank, after waiting piston to weld to change piston; The vacuum chamber sealing, and open hermatic door, vacuum chamber and vacuum tank air pressure inside are maintained an equal level rapidly; And air pressure is closed hermatic door near vacuum again, utilizes first vavuum pump to be evacuated to vacuum to the environment near vacuum in the vacuum chamber; More quick and convenient; Can reduce the time that vacuumizes, thereby reduce the stand-by period that welding equipment vacuumizes, can improve the welding efficiency of piston and the utilization rate of welding equipment.
