Sand cleaning equipment used for removing heavy casting sand core

Abstract

Provided is sand cleaning equipment used for removing a heavy casting sand core. The sand cleaning equipment used for removing the heavy casting sand core comprises a working table, more than one air-hammer mechanisms, a lifter used for loading and unloading castings and a noise reduction bin arranged outside the working table. The working table is provided with a sand outlet. The air-hammer mechanisms comprise more than one air hammers, air hammer supporting posts and air hammer lifting mechanisms. The air hammer lifting mechanisms are used for adjusting the positions of the air hammers on the air hammer supporting posts. Air hammer supporting sleeves are arranged on the air hammer supporting posts in a sleeved mode, and the air hammers are connected with the air hammer supporting sleeves. The air hammer lifting mechanisms comprise lead screws and lead screw nuts arranged on the lead screws in a sleeved mode. The lead screw nuts are connected with the air hammer supporting sleeves through a lower fixing plate. Hand wheels are arranged at the upper ends of the lead screws, and bearings used for being matched with the hand wheels to rotate the lead screws are arranged on the lead screws. The noise reduction bin is provided with a movable bin door, and a groove is formed in the top of the noise reduction bin. According to the sand cleaning equipment used for removing the heavy casting sand core, products on the working table are vibrated rapidly through the air hammers, so that sand cores in the products are separated from workpieces, and sand residues subjected to vibration slip into a waste sand recovery position through the sand outlet. The sand cleaning equipment used for removing the heavy casting sand core has the advantages of being high in production efficiency, low in labor intensity of workers and low in noise.

Description

technical field [0001] The invention belongs to the field of casting technology equipment, and in particular relates to a sand cleaning equipment used for cleaning large-scale casting sand cores. Background technique [0002] At present, many castings containing sand cores weigh more than 50Kg. When cleaning the sand cores, they are manually moved and turned, and a large hammer is used to hit the riser. The products are not easy to move, the labor intensity of the workers is high, the production efficiency is low, and the working environment nasty issues. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a sand cleaning equipment for cleaning large-scale casting sand cores with high production efficiency, low labor intensity and low noise. [0004] The technical solution of the present invention is: including a workbench for placing sand core castings to be cleaned, more tha...
