Embodiment 1

[0025] Such as figure 1 As shown, the vibrating core sand removing device of the present embodiment includes a lifting seat 4 located above the motorized roller table 11, a telescopic cylinder 3 located at both ends of the lifting seat 4, two cylinders 3 are fixed by a bracket 2, and the middle part of the bracket 2 An air hammer 1 is provided, and a vibrating beam 9 is arranged under the lifting seat 4. The vibrating beam 9 is set on the lifting seat 4 through a shock absorber. In the middle of the vibrating beam 9, the hammer handle 5 of the air hammer 1 moves up and down and directly acts on the hammer head 6. The cylinder 3 drives the lifting seat 4 to move, so that a certain distance is formed between the hammer handle 5 and the hammer head 6, and at the same time, the casting 10 With a certain pre-compression force, the air hammer handle 5 hits the hammer head 6, the hammer head 6 hits the vibrating beam 9, and the vibrating beam 9 hits the casting 10 to realize the purp...

Abstract

The invention relates to a vibrating core sand removing device. The vibrating core sand removing device comprises a lifting seat arranged above a workpart conveying mechanism and air cylinders arranged at two ends of the lifting seat, wherein the two air cylinders are fixed through a support; an air hammer is arranged in the middle of the support; a vibrating beam is arranged below the lifting seat; the vibrating beam is arranged on the lifting seat through a damping part; a hole is formed in the middle of the lifting seat; a hammer head is arranged in the middle of the vibrating beam throughthe hole; a hammer handle of the air hammer moves up and down and directly acts on the hammer head; and the lifting seat is driven by the air cylinders to move to make the hammer head be away from thehammer handle to a certain height. According to the vibrating core sand removing device, the vibrating force is effectively transmitted to the workpart, the vibrating effect is good, and the defect that an existing vibrating effect is good is overcome; and the device is low in cost and convenient to replace.

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...
