Cast iron burring method

Abstract

The invention provides a cast iron burring method which has the advantages that operation is convenient and cost is low. According to the technical scheme, the method includes the steps that firstly, cast iron is heated to 800DEG C and quickly cooled to normal temperature; secondly, a burring knife rotating by 1000 revolutions per minute is used for grinding; thirdly, low-temperature cooling is carried out; fourthly, the burring knife rotating by 1000 revolutions per minute is used for secondary grinding; fifthly, scrap iron and iron powder are removed through a hairbrush. Above all, compared with the prior art, the cast iron burring method is easy and convenient to realize, low in cost and very good in effect.

Description

Technical field [0001] The present invention is a casting technology field, which involves a method of removing cast iron and burrs. Background technique [0002] After the cast iron is formed, a large amount of burrs will be left on the surface of the cast iron, so that the remaining burrs will affect the use of cast iron and reduce the qualification rate of the workpiece. Invention content [0003] In response to the lack of existing technology, the present invention provides a way to remove cast iron and burrs with convenient operation and low cost. [0004] The technical solution of the present invention is a method of removing cast iron and burrs. The steps of removing cast iron and burrs are as follows:. [0005] Step 1: Heat the cast iron to 800 degrees Celsius and quickly cool to room temperature; [0006] Step 2: Use a speed of 1000 rpm to polish each minute; [0007] Step 3: low temperature cooling; [0008] Step 4: Use the speed of 1000 rpm to remove the bayonet for t...
