Processing system for machining of falling sand of sand casting and reutilization of moulding sand

Abstract

A processing system for machining of falling sand of sand casting and reutilization of moulding sand comprises a working table, a box body, a friction mechanism and a conveying mechanism. The left endof the upper surface of the working table is provided with the box body, and the upper end of the box body is provided with the friction mechanism; and the conveying mechanism is arranged below the friction mechanism. According to the processing system for machining of the falling sand of sand casting and reutilization of the moulding sand, the design concept of mechanical friction is adopted formachining casting falling sand, and primary removal of an adhesive covering film on the surface of the falling sand can be achieved through the friction mechanism arranged in the system; and sufficient time can be provided for removing the covering film on the surface of the falling sand in a grinding mode while the falling sand is conveyed through the arranged conveying mechanism, so that the reutilization efficiency of the falling sand is improved.

Description

technical field [0001] The invention relates to the field of sand casting processing in sand casting, in particular to a secondary utilization treatment system for sand casting in sand casting processing. Background technique [0002] In the field of casting processing, the commonly used casting method is sand casting, which is generally used for steel, iron and most non-ferrous alloy castings. The process is simple and easy to operate, and the molding materials are cheap and easy to obtain. It has always been the basic process in casting production. Usually after the sand casting is completed, after the casting is taken out, a large amount of molding sand will be bonded to the surface of the casting, and it needs to be treated with shakeout before the casting can be used, and these shakeout can be reused after processing, old sand Regeneration usually adopts mechanical friction method, fuel heating method and other methods to remove the failed or non-failed adhesive coating...

AI Technical Summary

Problems solved by technology

[0003] 1. The friction treatment efficiency of the friction device used in the common mechanical friction method is low, and it is easy to cause the adhesive coating film attached to the surface of the falling sand to be cleaned incompletely, thereby reducing the subsequent secondary utilization of the falling sand Rate;

[0004] 2. During the mechanical friction process of falling sand, the falling adhesive coating film has not been collected and processed in a timely and effective manner, which makes the adhesive coating film easy to mix with the treated falling sand, which in turn leads to The overall quality of the final shakeout is lower
