  5052合金鋁板的粘模問題出現在板與模具的交界處,可以改善兩面的表面。在印版上,可以進行表面紋理處理來改善表面形貌,達到在印版表面藏油的目的。如采用噴丸、電火花、激光等方法,鋁板生產廠家對整理輥的表面進行微粗化(毛)處理。印版在進入卷取機之前,其表面像一個指紋,留下無數微坑。
  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.
  對于沖壓工藝而言,這些微坑是眾多的潤滑油儲罐。這里的秘訣是當表面有“微麻形態”的板子在模具上滑動時,更多的潤滑油可以跟著進入變形區;變形區接觸壓力越大,微儲層擠出的潤滑油越多。整理輥表面如未進行微粗化,或使用時間過長使粗化輥表面的微峰、微凹處光滑,則載油能力下降。進入變形區后,當需要潤滑油以減少摩擦時,無油可用,會出現粘度型問題。

  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.
  在對鍍鋅鋁合金板表面進行磷化處理后,在顯微鏡下觀察到外層的磷酸鋅轉化膜,它就像一個多孔的開槽海綿,給潤滑油提供了大量的藏身之處。當需要潤滑油時,可在變形區通過較高的接觸壓力進行擠壓。
  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合金鋁板的表面,預涂上干潤滑劑,也是一個不錯的辦法。所謂的干潤滑油是一種高粘度的潤滑油,由輥在前面的板和蠟在室溫下。干性潤滑劑真是個好東西,能有效隔離板料與模具表面的接觸,大大減少摩擦,管拉制成型的人喜歡它。
  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.
  干潤滑劑也有不利的一面,流動性差,潤滑劑不容易跑到一邊的沖孔切邊模具,模具沒有油膜保護,剪切碎片很容易積累在上面,導致切割模具的問題(磨損)。原合金鋁板淺層拉出使用的潤滑油,沒有任何問題,每次落料時,濺起的一點潤滑油就足以濕潤沖頭一側。為了解決沖切模具的磨損問題,需要對沖切模具的側面進行拋光和PVD涂層。
  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.
