Cast bearing ring taking-out device

Abstract

The invention relates to a cast bearing ring taking-out device, and belongs to the field of bearing casting equipment. The cast bearing ring taking-out device comprises a sliding plate, a mounting block, a first rotating shaft, a first supporting frame, wheels, a bottom plate, a rotating disc, a positioning rotating column, a second supporting frame, a concave frame, a third supporting frame, a second rotating shaft, a lever and an internal expansion assembly; the mounting block is arranged on the back of the sliding plate, the mounting block is matched with the first rotating shaft, the first rotating shaft is mounted on the supporting frame, and the first supporting frame is arranged on the bottom plate; and the wheels are arranged at the bottom of the bottom plate, the positioning rotating column is arranged in the middle of the bottom plate, the rotating disc is arranged on the periphery of the positioning rotating column in a matched manner, the second supporting frame is arranged on the rotating disc, and the concave frame is arranged in the middle of the second supporting frame. Through cooperation of the internal expansion assembly and the lever, a bearing ring can be rapidly taken out, and the situation that sliding happens due to excessive stress caused by too small contact area, the inner wall of the bearing ring is damaged, and even the equipment structure is damaged is avoided.

Description

technical field [0001] The invention relates to a device for taking out a casting bearing ring, which belongs to the field of bearing casting equipment. Background technique [0002] For some larger bearing outer rings, it is usually produced by centrifugal casting. Centrifugal casting is a technology and method that injects liquid metal into a high-speed rotating mold, and makes the molten metal centrifugally move to fill the mold and form a casting. Due to the centrifugal movement, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting; a cylindrical inner hole can be obtained without a core; it is helpful for the removal of gas and inclusions in the liquid metal; it affects the metal Crystallization process, thereby improving the mechanical and physical properties of the casting.

Problems solved by technology

[0003] In the centrifugal casting process of the bearing ring, after it is cast by the centrifugal casting machine, people need to use tools such as steel hooks to hook it out. Since the casting is not long after forming, and it is in a high temperature state, the whole body is red hot. This process often More dangerous, prone to accidents
