5052合金铝板冲压如果出现粘模如何处理?

  5052合金铝板的粘模问题出现在板与模具的交界处,可以改善两面的表面。在印版上,可以进行表面纹理处理来改善表面形貌,达到在印版表面藏油的目的。如采用喷丸、电火花、激光等方法,铝板生产厂家对整理辊的表面进行微粗化(毛)处理。印版在进入卷取机之前,其表面像一个指纹,留下无数微坑。
  The sticking problem of 5052 alloy aluminum plate occurs at the junction of the plate and the mold, which can improve the surface of both sides. On the printing plate, the surface texture treatment can be carried out to improve the surface morphology and achieve the purpose of oil storage on the plate surface. For example, by means of shot peening, electric spark and laser, the surface of finishing roller is slightly roughened (roughened) by aluminum plate manufacturer. Before the plate enters the coiler, its surface looks like a fingerprint, leaving numerous micro pits.
  对于冲压工艺而言,这些微坑是众多的润滑油储罐。这里的秘诀是当表面有“微麻形态”的板子在模具上滑动时,更多的润滑油可以跟着进入变形区;变形区接触压力越大,微储层挤出的润滑油越多。整理辊表面如未进行微粗化,或使用时间过长使粗化辊表面的微峰、微凹处光滑,则载油能力下降。进入变形区后,当需要润滑油以减少摩擦时,无油可用,会出现粘度型问题。

  For stamping process, these micro pits are numerous lubricating oil tanks. The secret here is that when the board with "micro hemp shape" on the surface slides on the mold, more lubricating oil can follow into the deformation area; the greater the contact pressure in the deformation area, the more lubricating oil extruded from the micro reservoir. If the surface of the finishing roller is not slightly roughened, or if the use time is too long to make the surface of the roughening roller smooth, the oil carrying capacity will decrease. After entering the deformation zone, when lubricating oil is needed to reduce friction, no oil is available and viscosity type problems will occur.
  在对镀锌铝合金板表面进行磷化处理后,在显微镜下观察到外层的磷酸锌转化膜,它就像一个多孔的开槽海绵,给润滑油提供了大量的藏身之处。当需要润滑油时,可在变形区通过较高的接触压力进行挤压。
  After phosphating the surface of the galvanized aluminum alloy plate, the zinc phosphate conversion film on the outer layer is observed under the microscope, which is like a porous slotted sponge, providing a large number of hiding places for lubricating oil. When lubricating oil is needed, it can be extruded by high contact pressure in deformation area.
  在5052合金铝板的表面,预涂上干润滑剂,也是一个不错的办法。所谓的干润滑油是一种高粘度的润滑油,由辊在前面的板和蜡在室温下。干性润滑剂真是个好东西,能有效隔离板料与模具表面的接触,大大减少摩擦,管拉制成型的人喜欢它。
  It is also a good way to precoat the surface of 5052 alloy aluminum plate with dry lubricant. The so-called dry lubricating oil is a kind of high viscosity lubricating oil, which is composed of rollers in front of the plate and wax at room temperature. The dry lubricant is really a good thing, which can effectively isolate the contact between the sheet metal and the surface of the mold, greatly reducing the friction. The people who draw the tube like it.
  干润滑剂也有不利的一面,流动性差,润滑剂不容易跑到一边的冲孔切边模具,模具没有油膜保护,剪切碎片很容易积累在上面,导致切割模具的问题(磨损)。原合金铝板浅层拉出使用的润滑油,没有任何问题,每次落料时,溅起的一点润滑油就足以湿润冲头一侧。为了解决冲切模具的磨损问题,需要对冲切模具的侧面进行抛光和PVD涂层。
  The dry lubricant also has the disadvantage of poor fluidity. The lubricant is not easy to run to one side of the punching and trimming die. The die has no oil film protection, and the shear debris is easy to accumulate on it, which leads to the problem (wear) of the cutting die. There is no problem with the lubricating oil used to pull out the shallow layer of the original alloy aluminum plate. Every time the material is dropped, a little splashed lubricating oil is enough to wet one side of the punch. In order to solve the wear problem of punching die, it is necessary to polish and PVD coat the side of punching die.
