Definitions

  • the invention relates to the technical sector of the treatment of metal parts, more particularly methods of modifying surfaces made in the liquid phase.
  • the parts are attached to specific assemblies.
  • This technique is particularly applicable in the case of large parts or for small series. With this technique, it appears that the contact zone between the assembly and the part is isolated from the reaction medium, so that at this level area, treatment is poorly done or even not performed at all.
  • the parts are arranged in bulk inside a rotating barrel.
  • the parts collide which is a source of scratches and defects themselves generating chipping or pitting corrosion.
  • EP 0399349 discloses a device for treating cylindrical parts, used in the electronic industry. This device consists of trays inclined to the vertical, mounted on a rotary horizontal axis. These plates have points implanted perpendicular to their surface and capable of receiving the cylindrical parts. When the axis rotates, the workpieces rotate around the tips and change orientation.
  • this device operates with the continuous rotation of the cylindrical parts around the points, which generate friction on the periphery of each part.
  • the parts to be treated may get stuck and therefore not turn on themselves. For this reason, it is necessary to tilt the trays receiving the parts at an angle between 60 ° and 75 °. Given such an orientation of the plates, it appears that a generator of the bore of the part will not be treated, since it will be masked by the tip.
  • the object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
  • the problem which the invention proposes to solve is to be able to apply a phosphating or other treatment process, in the case of parts of complex shapes with the aim of to obtain a treatment of very good quality on all of the different zones of the parts, which must not have contact with each other during the treatment, with the further objective of avoiding masking any zone of the part during the treatment and finally to be able to very easily dispose of the parts to be treated.
  • a device for the treatment of specially shaped parts, which comprises support grids equipped with means able to allow centering and positioning in an orderly manner with limited displacement capacity, parts to be treated, without contact with each other, said grids being arranged in horizontal parallel rows, in an openwork box immersed in a treatment bath and subject to rotation drive means.
  • the grids are spaced at a determined interval to leave an empty space above the parts to be treated, to allow them to move. by gravity with respect to the centering means at the time of rotation of the box.
  • the centering and positioning means are constituted by pins integral with the support grids, and whose section is shaped to cooperate with the bore of the parts to be treated.
  • the pins can be arranged so as to cooperate with the outside of the part.
  • the box has mesh walls and is positively driven in rotation, by means of a motor member controlled by a control unit.
  • Figure 1 is a longitudinal sectional view of an embodiment of a part to be treated.
  • Figure 2 is a schematic longitudinal sectional view of the support grids equipped for positioning and centering of the parts to be treated.
  • FIG. 3 is a plan view corresponding to FIG. 2.
  • Figure 4 is a longitudinal sectional view of the box equipped with different grids and immersed in the phosphating bath.
  • Figure 5 is a view corresponding to Figure 4, during the rotation of the boxes.
  • Figure 6 is a cross-sectional view taken along line 6.6 of Figure 4.
  • the device according to the invention essentially comprises a box (1) in which are mounted support grids (2) equipped with means (3) capable of allowing centering and positioning in an orderly manner parts to be treated (4).
  • the entire box (1) with the grids (2) is immersed in a bath (B).
  • the walls (1a) of the box (1) are perforated to allow the pieces (4) positioned on the grids (2) to be immersed in the bath (B).
  • all of the walls (1a) of the box (1) are screened.
  • This box (1) can have a generally parallelepiped shape.
  • this box (1) is shaped to be rotated by any known and appropriate means.
  • the box (1) is driven by means of a motor member controlled by a control unit.
  • the centering and positioning means (3) consist of pins integral with the support grids (2). These pins (3) are shaped in section, to cooperate with the bore (4a) of the parts to be treated, while allowing limited movement of the parts, relative to said pins.
  • the centering pins (3) allow, during the rotational drive of the box (1), corresponding to the treatment to be carried out, the movement of the parts (4) to allow them to be treat in their entire area, avoiding any contact between said parts that could adversely affect the quality of the treatment.
  • the grids (2) are arranged in parallel rows in the box (1).
  • the box (1) has any type of arrangement allowing, on the one hand, the introduction and removal at will of the grids and, on the other hand, the positioning of the grids inside the box, according to determined and variable intervals (E).
  • the intervals (E) are determined as a function of the height (H) of the parts to be treated, to leave an empty space between the upper part of the parts and the grid located immediately above. This space allows the displacement by gravity of the parts (4), relative to their means of centering and positioning (3), at the time of rotation of the box or not.
  • the grids (2) are arranged in a horizontal plane.
  • the device according to the invention finds a particularly advantageous application for the treatment of parts of complex shapes, such as those illustrated in FIG. 1.
  • the part (4) is in the form of a hollow cylindrical body with, in its upper part, a circular peripheral rim (4b) internally curved constituting a flange.
  • the parts (4) are positioned in an orderly fashion on the support grids (2) while being centered on the pins (3).
  • the different grids (2) are positioned inside the box (1) respecting the intervals (E) to obtain the spaces (e).
  • the entire box thus equipped is immersed in the bath (B) ( Figures 4 and 6).
  • the rate of rejects is only between 1 and 3%.
  • the device according to the invention is applicable for the treatment of other types of parts such as hydraulic components for portable tools of the pruning type and of a generally cylindrical shape, of reduced diameter, and having a coaxial bore of reduced diameter.
  • the positioning and centering of the parts under the conditions indicated above, that is to say with limited displacement capacity, are carried out by pins cooperating with the outside of the part, to allow filling of the by the bath.
