Deburring, chamfering these small processes are often in the work can not be underestimated, today we summarize some of the information shared in the past, hoping to bring help to everyone’s work.

手工作品

传统修边刀逐渐取代了这些传统方法,无需进行技术处理,节省成本和环境保护。  

化学方法

根据电化学反应原理,金属零件的去毛刺可以自动,选择性地进行。可广泛用于气动,液压,工程机械,喷油泵,汽车,发动机等行业的泵体,阀体,连杆,柱塞针阀对等金属零件的去毛刺。适用于难以去除的内部毛刺,热处理和精加工后的零件。   

电解法

一种通过电解对金属零件进行去毛刺的电化学加工方法。将工具阴极(通常是黄铜)固定在工件的毛刺部分附近,并在它们之间留有一定的间隙(通常为0.3-1MM)。工具阴极的导电部分与毛刺边缘对齐,其他表面覆盖有绝缘层,因此电解集中在毛刺部分。在加工过程中,工具的阴极与直流电源的负极相连,工件与直流电源的正极相连。压力为0.1-0.3 MPa的低压电解液(通常为硝酸钠或氯酸钠水溶液)在工件和阴极之间流动。当连接直流电源时,毛刺将产生阳极溶解并被去除,然后被电解液带走。电解液在一定程度上具有腐蚀性。去毛刺后,应清洁工件并进行防锈处理。电解去毛刺适用于对隐藏零件中的交叉孔或复杂零件进行去毛刺。它具有很高的生产效率,仅需几秒钟到几十秒钟。该方法通常用于对齿轮,花键,连杆,阀体和曲轴油道孔进行去毛刺,以及修整尖角。缺点是零件附近的毛刺也会受到电解的影响,表面会失去原有的光泽,甚至会影响尺寸精度。  

超声波法

When the ultrasonic energy generated by ultrasound acts on the liquid in which the vibration is in a sparse state, it will tear into very small holes (that is, the internal is a vacuum). These holes will generate up to hundreds of atmospheric pressure instantaneous pressure when they break, which is called cavitation phenomenon. Ultrasonic deburring is to use the instantaneous impact force of hundreds of atmospheric pressure produced by “cavitation phenomenon” to remove the burrs attached to the parts. Ultrasonic deburring is not applicable to all burrs, mainly for some micro burrs. Generally, if the burrs need to be observed by a microscope, we can try to remove them by ultrasonic method. For the visible burr, it mainly depends on the bonding strength. The burr with weak bonding strength can be treated by ultrasonic. Generally, if the burr can only be treated by the cutter, the ultrasonic method is not available at all. Advantages and disadvantages of ultrasonic deburring.

高压水喷射法

顾名思义,它以水为介质,利用瞬时冲击力去除加工后产生的毛刺和毛边,同时达到清洗的目的。经过多次测试,发现合适的压力为30mpa-50mpa。如果压力不足,则不能获得去毛刺效果。如果压力太高,可以去除毛刺,但是有损坏工件的危险。通常,液压部件在使用时承受的液压压力在20MPa以内,而毛刺残留在50MPa的压力下无法去除。在数MPa的工作压力下掉落的可能性很小,也可以认为毛刺的根部残留是工件的一部分。高压去毛刺设备的制造商越来越多,可以简单地分为两类:工件移动式和喷嘴移动式。工件移动式成本低廉,适用于简单阀体的去毛刺和清洗。缺点是喷嘴与阀体的配合度不理想,阀体内的横孔和斜孔的去毛刺效果不佳。喷嘴移动式可有效调节喷嘴与阀体之间产生毛刺的距离,通过CNC控制有效地对应于阀体内横孔,斜孔和盲孔的毛刺,但造成盲孔的毛刺由于该设备的高成本,只有汽车的心脏和工程机械的液压控制系统才能享受这种待遇。

热爆炸法

Also known as electric thermal deburring, thermal deburring is recognized as the most suitable advanced technology for large-scale deburring of small workpieces in the world’s machinery manufacturing industry. Only two domestic enterprises can produce this equipment. It uses hydrogen and oxygen to mix in the closed chamber which is used to treat the workpiece, ignites and burns instantly, and has a violent thermochemical reaction with the workpiece surface burr in a very short time, so as to achieve the purpose of burr removal. Thermal deburring is a special processing technology, which has the characteristics of high efficiency, high universality, good accessibility, even and thorough deburring, smooth workpiece surface, and not limited by workpiece material, shape and burr position. It is especially suitable for deburring of workpieces with complex cavity, intersecting hole system, deep hole, blind hole, threaded hole and other difficult deburring which cannot be solved by other process methods. It can be used for deburring of non-metallic materials such as black, non-ferrous metals and thermoplastics, and for deburring of metal die casting and plastic parts. Because of its high processing efficiency and low direct cost for production, it is especially suitable for large-scale continuous production environment. It is an ideal efficient processing equipment for large-scale industrial production.  

冷冻修整方法

The thickness of the flash (or burr) of rubber, plastic products, zinc magnesium aluminum alloy and other products is much thinner than that of the products, so the embrittlement speed of the flash (or burr) is faster than that of the products. In the period when the flash (or burr) is embrittlement and the products are not embrittlement, the frozen deburring (trimming) machine strikes the products by shooting projectiles, so as to remove the products in embrittlement The flash (or burr) of. The frozen deburring (trimming) machine is a kind of quick embrittlement of rubber, plastic products, zinc magnesium aluminum alloy flash by using the ultra-low temperature of liquid nitrogen. In this state, the frozen particles ejected at high speed impact the product’s burr (or Flash), so as to not only remove the product’s burr (or Flash) with high quality and efficiency, but also keep all of the product itself Special deburring (trimming) equipment with unchanged physical properties. It can greatly improve the trimming (deburring) accuracy of products and has a high degree of intensification. This kind of equipment has become an indispensable equipment for finishing and deburring of precision rubber and plastic products and die-casting enterprises.
