A vibrating core sand removal device

Abstract

The invention relates to a vibrating core sand removal device, which comprises a lifting seat arranged above a workpiece conveying mechanism, and air cylinders arranged at both ends of the lifting seat. The two air cylinders are fixed by brackets. The vibrating beam is set on the lifting seat through the shock absorber. There is a hole in the middle of the lifting seat. The hammer head is placed in the middle of the vibrating beam through the hole. The hammer handle of the air hammer moves up and down and directly acts on the hammer head. Drive the lifting seat to move, so that the hammer handle is at a certain height from the hammer head. The vibration force of the invention is effectively transmitted to the workpiece, the vibration effect is good, the existing problem of unsatisfactory vibration effect is overcome, the cost is low, and the replacement is convenient.

Description

technical field [0001] The present application relates to a device for removing cored sand, in particular to a device for vibrating cored sand. Background technique [0002] The cleaning of casting core sand is usually achieved by using a pneumatic vibrating unit (air hammer) to vibrate the casting at high frequency in the equipment to loosen and scatter the core sand in the casting. [0003] The existing vibrating core sand removal device uses an air hammer as a vibrating source to hit the vibrating beam, and the vibrating beam hits the casting to achieve the purpose. Using this method to clean the residual core sand of castings is not ideal, and the reliability of the equipment is poor. Simply increasing the size and strength of the pneumatic pick will greatly reduce the service life of hammer handles, hammer heads, vibrating beams and other components. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention pro...
