Cold forming process of reducer tee

Cold forming process of reducer tee

The reducer tee cold forming processing method is characterized in that it adopts an integral hydraulic bulging process, uses a lubricant to lubricate the surface of the metal tube blank, and reasonably controls the size of the punch, the feed distance, and the feeding time. Form high-quality pipe with uniform wall thickness in the mold; the specific operation steps of the tee machine are as follows:
1 Prepare the oblique tee metal tube to be machined;
2 Lubricant is used to lubricate the surface of the tube blank and placed in the cavity under the inclined tee, and accurate positioning is performed.
3 Control the clamping process through the hydraulic system and control the clamping force, and control the feed distance and time of the left and right punches through the hydraulic system of the tee machine, and at the same time, the punch feed and internal pressure can be well matched;
4 When the left and right punches move to the specified position, stop the feed and release the internal pressure, and then release the oblique tee pipe;
5 The semi-finished products are subjected to solution treatment, shaping, beveling, grinding and sandblasting to prepare finished metal oblique tee fittings.
