Description

Technical Field

[0001] The utility model relates to the technical field of steel production equipment, in particular to a core rod cooling device. Background Art

[0002] The mandrel is a component of the die used to form the contour surface in the compact or sintered body in the pressing direction. It is mainly the inner die of seamless steel pipes. With the increasing requirements for seamless pipe production in pipe jacking units, the requirements for the mandrels of key deformation tools and dies are becoming more and more stringent. The temperature uniformity of the mandrel directly affects the product quality, and cooling equipment is required to cool the mandrel.

[0003] According to Chinese patent publication number CN218109105U, a water-cooled metal core rod cooling device is disclosed. The device is provided with a pair of fixing structures, the metal core rod is placed on a pair of placement blocks, a pair of telescopic cylinders are driven, and the pair of telescopic cylinders drive a pair of fixing frames to move until the pair of fixing frames are in contact with the metal core rod to compress the metal core rod. A pair of actuators are activated, and the pair of actuators drive rubber blocks to move, which cooperate with the pads to further fix the metal core rod. The water pump in the cooling assembly is driven, and cooling water is sprayed out through the water outlet pipe, the water outlet head and the nozzle under the action of the water pump to cool the metal core rod. The sprayed water falls into a recovery water tank through a number of through holes.

[0004] However, this technical solution can only cool the core rods one by one. After a core rod is cooled, a new core rod needs to be re-clamped, which makes it difficult to quickly cool multiple core rods and is inconvenient for personnel to use. Therefore, we propose a core rod cooling device. Utility Model Content
