Definitions
- the invention relates to a method for surface pickling of metal parts. wherein the or the preferably pre-cleaned metal parts to be pickled is moved to a pickling bath filled with pickling liquid and is immersed in the pickling liquid and the pickling liquid is left to act on the metal part (s) and then the metal part (s) is lifted out of the pickling bath and optionally being rinsed in another bath.
- a disadvantage of this known method is that despite the repeated lowering and lifting of the metal part, there is no homogeneous pickling process on the surface, as a result of which various areas are poorly prepared for the subsequent surface coating process. Such a case occurs, for example, when large rust spots or scaling on the metal parts prevent attack by the pickling agent. There is therefore no reliably well-coated surface, which leads to frequent quality complaints and ultimately results in very low productivity.
- the object of the invention is therefore to provide a method of the type mentioned at the outset with which the substrate of the metal part to be coated which is as uniform as possible is created with very good adhesiveness.
- Another object of the invention is. increase the pickling speed required for each metal part and thereby increase productivity. According to the invention, this is achieved by immersing one or a predeterminable number of metal parts to be pickled in each of at least two or more pickling baths in a predeterminable sequence, the pickling liquid of the pickling bath being allowed to act on the immersed metal part (s), respectively These are then lifted out of the pickling bath, moved to the subsequent pickling bath and immersed.
- the pickling bath acting at the beginning of the sequence initially removes the coarsest impurities from the metal part or parts, while the subsequent pickling processes in the two or more pickling baths successively become less and less strong Pickling up impurities from the metal part surface, so that the same
- the metal part (s) is or are stopped after being lifted out of the pickling bath for dripping above the pickling liquid.
- all pickling baths can be operated with a very high degree of efficiency, because this means that all pickling baths are run through in parallel and none of them has an idle time.
- Pre-cleaning e.g. Degreasing baths and post-cleaning baths, e.g. Rinsing baths to be dipped.
- these baths create a better surface for the pickling to attack the metal parts and, on the other hand, they remove residues from the surface that remain after pickling.
- Another object of the invention is to provide a system with which the method according to the invention can be carried out in a simple manner.
- the pickling baths are arranged at the same distance from one another, wherein the pickling baths can preferably be arranged with their long sides parallel.
- the metal parts or groups of metal parts which can be fixed on uniformly spaced-apart cross beams a movable gantry crane carrying the crossbeams can be moved to the individual pickling baths.
- Metal parts can be moved very quickly from one pickling bath to the next one using a suitable crane system because only very short distances have to be covered between the pickling baths. This allows a further increase in
- Another feature of the invention can be that the pickling baths each have the same volume and the same pickling liquid filling.
- Number of items to be pickled must be managed. Due to the uniformity of the pickling baths, these can be arranged so that different requirements for one
- Production process can be fulfilled by the appropriate choice of the number of baths to be run.
- FIG. 1 shows a side view of a system according to the invention for carrying out the method according to the invention in a first method position
- FIG. 2 shows two further process positions of the system according to the invention according to FIG. 1 and
- FIG 3 shows a section through a pickling bath of the system according to the invention.
- liquid baths 1, 4, 21, 31 to 36, 40 and 41 of the same size, with their longitudinal sides arranged parallel to one another, are provided, some of which contain different liquids, with which the metal parts 7 are treated, a predetermined number from metal parts 7 to one each
- the six liquid baths 31 to 36 used in this embodiment are identical to The six liquid baths 31 to 36 used in this embodiment.
- the respective one or more are placed on the crossbeams 9
- Metal parts 7 are only intended to indicate that either part or several
- the metal part (s) 7 to be pickled is immersed in a position in each of the six pickling baths 31, ..., 36 in a predeterminable sequence, which in this exemplary embodiment consists in that the Parts 7 - based on the representation in FIGS. 1 to 3 - each pass through the six pickling baths 31, 32 .... 36 from right to left.
- the pickling liquid of the pickling bath 31, 32 ..., 36 is allowed to act on the immersed metal part 7 or the metal part group 7 in each position, and this is then lifted out of the pickling bath 31, 32 ... 36, in each case subsequent pickling bath 31, 32 .... 36 moved and immersed.
- the hydrochloric acid bath 1 is not part of the otherwise automated process and is used for dezincing missing parts, which is carried out manually.
- the subsequent immersion of the metal parts 7 in the individual baths 31 ... 36 has the effect that in the first pickling bath 31 a very large part of impurities on the surface of the metal parts 7 are first pickled and in the following pickling baths 32 ... 36 when immersed there is a decreasing degree of contamination.
- Fig. L the beginning immersion of the metal parts 7 in the baths 4, 21, 31, 32 and 33 is shown. Before that, for example, the position of metal parts 7 on the left most of the longitudinal cross members 6 has passed through all the baths 4, 21, 31 and 32 in cycles and is now immersed in the pickling bath 33. This is the third pickling bath after the first and second pickling baths 31, 32.
- the metal parts 7 located at this position are lifted out of the bath 33 at the same time as the metal parts at the other five positions of the longitudinal cross members 6 and in the next one Moved clock to the adjacent bath 34 and lowered where the effect of the pickling liquid can develop again. Since a large part of the contamination of the metal parts 7 has already been removed in the pickling baths 31, 32, only the remaining residues of the pickling liquid are attacked in the pickling bath 33.
- the next cycle brings a pickling through the bath 34 for the parts 7 that have just been lifted out of the bath 33, which in turn only has to deal with the residual contamination from bath 33. This process continues until all baths 31 ... 36 have been run through.
- FIGS. 1 to 4 still has a particularly advantageous possibility of carrying out the method. wherein the six metal parts 7 or metal part groups 7 spaced apart from one another by the respective center distance of the pickling baths 31, 32, ..., 36 are simultaneously immersed in the pickling baths 31, 31, ... 36 and the pickling liquid is allowed to act on them.
- these can be moved on the evenly spaced-apart cross members 9 from the metal parts 7 of the movable cross crane 8 carrying the cross members 9 to the individual pickling baths 31, 32 .., 36.
- the cross members 9 are held by the two longitudinal members 6.
- the pickling baths 31, 32, ..., 36 are arranged at the same distance from one another and are arranged parallel with their long sides. They each have the same volume and the same pickling liquid filling. This arrangement can also be chosen differently without leaving the scope of the invention.
