在压铸行业中,不论是锌合金压铸,还是铝合金压铸,原理都是差不多,自然工艺区别也就相差不大了,压铸去毛刺现象不论材质,都是不可避免的一个工艺。近年来随着铝合金压铸件质量的要求日益提高,人们对铝合金压铸件的毛刺要求也更加严格,毛刺方法也在不断更近。下面就给大家简单介绍目前去毛刺的方法,方便大家针对不同产品选择不同的去毛刺方法。
In the die casting industry, whether zinc alloy die casting or aluminum alloy die casting, the principle is the same, and the difference between natural processes is not big. Die casting deburring is an inevitable process regardless of material. In recent years, with the increasing quality requirements of aluminum alloy die castings, people have more strict requirements on the burr of aluminum alloy die castings, and the burr method is getting closer and closer. The following is a brief introduction to the current deburring methods to facilitate you to choose different deburring methods for different products.
1、人工去毛刺

Based on the principle of electrochemical reaction, the deburring operation of parts made of metal materials can be completed automatically and selectively.
适用对象:适用于难于去除的内部毛刺,适合泵体、阀体等产品细小毛刺(厚度小于7丝)。
Applicable object: it is applicable to internal burrs that are difficult to remove, and small burrs (thickness less than 7 wires) of pump body, valve body and other products.
8、电解去毛刺
8. Electrolytic deburring
利用电解作用去除铝合金压铸毛刺的一种电解加工方法。电解去毛刺适用于去除铝合金压铸件中隐蔽部位交叉孔或形状复杂零件的毛刺,生产效率高,去毛刺时间一般只需几秒至几十秒。
An electrochemical machining method for removing burr of aluminum alloy die casting by electrolysis. Electrolytic deburring is suitable for removing the burr of cross holes in hidden parts or parts with complex shape in aluminum alloy die castings. It has high production efficiency, and the deburring time generally takes only a few seconds to tens of seconds.
缺点:电解液有一定腐蚀性,零件毛刺的附近也受到电解作用,表面会失去原有光泽,甚至影响尺寸精度,铝合金压铸件去毛刺后应经过清洗和防锈处理。
Disadvantages: the electrolyte is corrosive to a certain extent, and the parts near the burr are also affected by electrolysis, which will lose the original luster on the surface and even affect the dimensional accuracy.

11、磨粒流去毛刺
11. Abrasive flow deburring
常规的振磨,对于孔洞类的毛刺难于应付,典型的磨粒流加工工艺(双向流),通过两个垂直相对的磨料缸推动磨料使其在工件和夹具形成的通道来回流动。磨料进入和流经通过被限制的任何区域都会产生研磨效果。挤出压力控制在7-200bar(100-3000 psi), 适用于不同的行程和不同的循环次数。
Conventional vibration grinding is difficult to deal with holes and burrs. The typical abrasive flow machining process (two-way flow) pushes the abrasive through two vertically opposite abrasive cylinders to make it flow back and forth in the channel formed by the workpiece and fixture. Abrasive entering and flowing through any restricted area will produce grinding effect. The extrusion pressure is controlled at 7-200bar (100-3000 psi), which is suitable for different strokes and different cycles.

12、磁力去毛刺
12. Magnetic deburring
磁力研磨加工是在强磁场作用下,填充在磁场中的磁性磨料被沿着磁力线的方向排列起来,吸附在磁极上形成“磨料刷”,并对工件表面产生一定的压力,磁极在带动“磨料刷”旋转的同时,保持一定的间隙沿工件表面移动,从而实现对工件表面的光整加工。
Magnetic abrasive machining is that under the action of a strong magnetic field, the magnetic abrasive filled in the magnetic field is arranged along the direction of the magnetic force line, adsorbed on the magnetic pole to form an "abrasive brush", and generates a certain pressure on the workpiece surface. While the magnetic pole drives the "abrasive brush" to rotate, it maintains a certain gap to move along the workpiece surface, so as to realize the finishing of the workpiece surface.
特点:成本较低、加工范围广、操作方便
Features: low cost, wide processing range and convenient operation
工艺要素:磨石、磁场强度、工件转速等
Process elements: grindstone, magnetic field strength, workpiece speed, etc
13、机器人打磨单元
13. Robot grinding unit
原理类似于人工去毛刺,只是将动力变为机器人。得到编程技术以及力控技术的支持,实现柔性打磨(压力与速度的变换),机器人去毛刺优势凸显。
