Abstract
The invention discloses a large coiler mandrel for cold-rolled strip steel. The coiler mandrel comprises a pyramid shaft consisting of a transmission section and a pyramid section, wherein the periphery of the transmission section is sleeved with a gear hollow shaft; fan-shaped plates are uniformly distributed at the periphery of the pyramid section; the periphery of the end of the pyramid section is sleeved with a fan-shaped plate positioning sleeve; a mandrel pull rod is arranged in the pyramid shaft; one end of the mandrel pull rod is connected with a rotating expansion and contraction cylinder, and the other end of the mandrel pull rod is connected with the fan-shaped plate positioning sleeve; the fan-shaped plate positioning sleeve is connected with the fan-shaped plates and panel strips; the rotating expansion and contraction cylinder is arranged in an inner cavity at the tail end of the gear hollow shaft; an inner cavity at the head end of the gear hollow shaft and a corresponding part of the transmission section have a conical surface matched structure; and the gear hollow shaft and the transmission section are fixed through a connecting piece to form a whole. The technical problem that the mandrel has large radial runout because the pyramid shaft and the gear hollow shaft of the conventional mandrel are in clearance sliding fit can be solved, the rotational inertia of the mandrel is reduced, and dents are prevented from being formed on the surface of the strip steel due to a gap between adjacent fan-shaped plates when the mandrel is expanded.
