热能去毛刺机
热能去毛刺机是一种去毛加工机械,热能去毛刺机的热能去毛刺过程是一种利用热化学反应过程。将所需去毛刺的零件,放在密封工作室内,然后充入一定量的甲烷气体(CH4)或煤气及氧气(O2)混合气体,经火花塞点火以后,混合气体在瞬间内反应,放出大量的热,使毛刺在高温(约3000℃),高压(充气压力的20倍),高速(8倍音速)作用下,加热自燃,而达到去毛刺的目的。因反应时间极短(仅0.003秒),所以加工后的零件原有尺寸,表面光洁度,金相组织及机械性能等基本没有变化。
由于气体的可达性好,无孔不入,故对形状复杂或手工难以去除毛刺的零件,如有内孔、交叉孔槽、盲孔等零件的毛刺具有独特的去除效果,该设备体积小、效率高(一个循环周期90秒)、去毛刺效果好,可满足大批量产需求,广泛用于机械、液压、气动、压铸、汽车、航空等领域。

The thermal deburring process is a thermal chemical reaction process. The under deburring parts are placed in a sealed chamber, and then filled with a certain amount of methane gas or gas and oxygen mixed gas. After ignited spark, the mixture reacts instantaneously and releases a lot of heat, which makes the burr heated under the action of 20 times high speed and eight times of high pressure at high temperature of about 3000 C. And to achieve the purpose of deburring. Because the reaction time is very short, only 0.003 seconds, the original size, surface finish, metallographic structure and mechanical properties of the parts after heated are basically unchanged.
