The invention discloses a mandrel vibration pipe making machine, which relates to the technical field of manufacturing equipment for cement pipes, in particular to the forming equipment for flexible joints, steel socket jacking pipes, and circular concrete pipes for slotting construction or jacking construction. The vibrating rod core of the mandrel vibrator is connected in the vibrating rod body through a bearing, a belt transmission device is arranged between the motor output shaft and the driven wheel, and the upper end of the driven wheel is coaxially and fixedly connected to the main bearing seat, which is arranged above the main bearing seat A vibrating rod core, the lower end of the vibrating rod core is fixedly connected with a spline, and the upper end of the main bearing seat is coaxially fixed with a spline sleeve, and the spline is matched in the spline sleeve. The spline transmission of the utility model is a multi-tooth transmission, with high bearing capacity, small stress concentration, and small weakening of the strength of the shaft and the hub, so that the service life of the vibrator is prolonged, the transmission torque is large, the efficiency is high, and the production efficiency and energy utilization are improved. Rate.
