Full-automatic double-end pipe shrinking machine for heat pipe

The invention discloses a full-automatic double-head pipe shrinking machine for a heat pipe, which is high in processing efficiency, does not need to change edges for double-head pipe shrinking of the heat pipe, and effectively improves the controllable precision of pipe shrinking. The full-automatic double-end pipe shrinking machine for the heat pipe comprises a conveying mechanism, a stock bin mechanism, a left pipe shrinking mechanism, a right pipe shrinking mechanism and a clamping mechanism. The stock bin mechanism is used for storing heat pipes and sending out the heat pipes one by one, the conveying mechanism conveys the sent-out heat pipes to the clamping mechanism, the clamping mechanism clamps and positions the heat pipes, and the left pipe shrinking mechanism and the right pipe shrinking mechanism conduct pipe shrinking on the two ends of the clamped and positioned heat pipes in sequence. The left pipe contracting mechanism and the right pipe contracting mechanism respectively comprise a carry driv
