A machine for post-processing of precision casting three-way valves

Abstract

The invention relates to a machine for post-processing of precision casting three-way valves. An electric slider is installed on the left end, and a clamping device is installed on the electric slider. A connecting rod is installed on the right end of the working frame. The ejecting end of the connecting rod is connected with the coring device by pushing the cylinder. There is an inflatable device, and the inflatable device is installed at the bottom of the work frame. The invention can solve the problem that due to the small internal space of the three-way valve and the blurred line of sight, it is difficult to completely clean the inside of the three-way valve by manual sand cleaning, and the transitional use of tools for sand cleaning may cause wear on the inner wall of the three-way valve. If random crushing is carried out, the direct collision between the tool and the inner core sand will easily cause the tool to deform, and the high temperature generated by the friction between the two will easily lead to problems such as overheating of the tool surface.

Description

technical field [0001] The invention relates to the field of three-way valve processing, in particular to a machine for post-processing of precision casting three-way valves. Background technique [0002] Precision casting refers to the general term for the process of obtaining precision-sized castings. The products processed by precision casting are precise, complex, and close to the final shape of the parts, and can be used directly without or with little processing. Precision casting includes sand cavity casting and ceramic casting. , metal mold casting, pressure casting, lost foam casting, commonly used three-way valves usually use sand cavity casting, three-way valves need shelling and sand cleaning after production, and the commonly used sand cleaning work usually manually cleans the inner wall of the three-way valve. This sand cleaning method often has the following defects: [0003] 1. Due to the small internal space of the three-way valve and the blurred vision, it...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the small internal space of the three-way valve and the blurred vision, it is difficult to completely clean the inside of the three-way valve by manual sand cleaning. Excessive use of tools for sand cleaning may cause wear on the inner wall of the three-way valve;

[0004] 2. Personnel usually use knives to randomly crush the inner core sand. When the tool directly collides with the inner core sand, it is easy to cause the tool to deform, and the high temperature generated by the friction between the two is likely to cause the surface of the tool to overheat, thereby shortening its service life.
