Problems solved by technology
The cutting object of CNC machining of casting molds is sand molds. Sand blocks may be produced during low-speed machining; during high-speed cutting, irregularly moving sand debris splashes fast, and the waste debris splashed on the sand molds will damage the surface quality of the sand molds and affect the follow-up. The casting accuracy is high, and the sand debris remaining in the model gap will cause harmful friction with the tool, which will aggravate the tool wear and reduce the service life of the tool

The invention discloses a sand drainage method for cast nc processing. The method includes the following steps: a) a nozzle is arranged near a processing tool bit and is led to right face to the tool bit; b) the nozzle is connected with a valve and a gas pump arranged on a windpipe through the windpipe; c) during the cast nc processing process, the gas pump and the valve are opened to lead the compressed gas in the gas pump to be sprayed out from the nozzle along the windpipe; d) the flux of the compressed gas is adjusted according to the amount of the wasted sand generated during a cast milling process to lead the waste sand near the tool bit to be drained in time. The nozzle is arranged near the tool bit and at the position right facing to the tool bit in the device; the nozzle is connected with the valve and the gas pump through the windpipe. The method can realize instant milling and instant blowing to transfer the waste sand, reduce the effect of the sand grains remained in the surface of a die on the precision of the die and the abrasion of the sand grains to the tool bit as well as improve the cast surface precision and the service life of the tool bit. The device has the advantages of easy control, low cost and broad application.
Description
technical field [0001] The invention belongs to the field of accessories of special processing machine tools, and in particular relates to a sand discharge method and a device for casting numerical control cutting processing. Background technique [0002] In the casting process of CNC machining, the problem of sand discharge is the main problem affecting the cutting precision and tool life. The cutting object of CNC machining of casting molds is sand molds. Sand blocks may be produced during low-speed machining; during high-speed cutting, irregularly moving sand debris splashes fast, and the waste debris splashed on the sand molds will damage the surface quality of the sand molds and affect the follow-up. The casting accuracy is high, and the sand debris remaining in the model gap will cause harmful friction with the tool, which will aggravate tool wear and reduce tool life. Therefore, timely and thorough sand removal is the key technology that needs to be solved in the pro...
