Rotating device for lost foam casting

Abstract

The invention provides a rotating device for lost foam casting. The rotating device comprises a sand feeding pipe, a spiral conveyor, a first bearing seat, a second bearing seat, a motor, a coupler and a supporting frame. A sand inlet is formed in the upper portion of the sand feeding pipe, and a sand outlet is formed in the lower portion of the sand feeding pipe and located in the end, away fromthe sand inlet, of the sand feeding pipe; the spiral conveyor is mounted inside the sand feeding pipe and composed of a rotating shaft and a spiral conveyor blade, and the spiral conveyor blade wrapsthe rotating shaft; the first bearing seat and the second bearing seat are arranged oppositely; the first end and the second end of the rotating shaft are rotatably connected with the first bearing seat and the second bearing seat correspondingly; the motor is connected with the rotating shaft through the coupler; a connecting flange is arranged on the lower portion of the sand feeding pipe and located at the end, away from the sand outlet, of the sand feeding pipe; a rotating bearing capable of rotating horizontally is arranged on the supporting frame; and the sand feeding pipe is horizontally mounted on the rotating bearing through the connecting flange. The sand feeding pipe in the rotating device can rotate horizontally with the rotating bearing as the axis, accordingly, the sand outlet can be adjusted in position, and sand transport is more flexible.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a rotating device for lost foam casting. Background technique [0002] The casting of smooth steel parts with high surface requirements such as steel balls can be realized by lost foam casting, and sand is needed in the lost foam casting process. In the prior art, the equipment for adding sand to the sandbox is bulky and inflexible, especially when there is sand in the sandbox, its weight increases sharply, resulting in inconvenient movement and high labor intensity. Moreover, in the prior art, since the sand outlet of the equipment is fixedly set, one sand filling equipment cannot meet the needs of multiple sandboxes, and the transportation of sand is not flexible enough. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a rotating device for lost foam casting. [0004] A rotatin...
