Abstract

Usage: the invention relates to electroplating, in particular to devices for chromium plating of rod parts with a bots-type head. Essence: a device for galvanic processing of parts includes a pipe 1, an item holder 2 in the form of truncated cones with ribs 3. The lower cone of the holder is made with a bevel 4, and the pipe 1 is hung rotatably on the rod 6. At the bottom of the bath 9 is offset from the center of the pipe 1 row of identical rollers at different heights. The workpieces 5 are laid into the holes of the cones of the part holder 2, and the assembled unit is hung on the current-carrying rod 10 by means of the hook 7. Then a swing mechanism is connected to the rod 10. When the taper 4 of the cone runs in succession on uneven rollers, in addition to reciprocating movement, the oscillating movement in the vertical plane will be communicated to the holder. In addition, the holder will rotate in different directions. As a result, parts in the electrolyte will make a complex movement, which intensifies the process of electroplating, i.e., labor productivity increases. This design of the electroplating device provides mixing and renewal of the cathode electrolyte layer, as well as the rapid removal of gas bubbles from the cathode surface. 2 Il. with s

Description

The invention relates to the galvanic machining of parts, in particular to devices for chromium plating of rod parts with a head like bolts.
A device for electroplating with oscillating rods, comprising an electroplating bath with a bracket, on which is placed a swing drive in the form of a gear motor, the latter is connected by a crank-rod mechanism with cathode rods installed in supports with centering longitudinal rollers and transverse rollers, with technological the current to the cathode rod is supplied by a busbar with a flexible link at the cathode rod.
The disadvantage of this device is the low productivity of the process due to insufficiently intensive mixing of the electrolyte in the cathode layer and slow removal of gas bubbles from the cathode surface, especially in hard-to-reach areas.
Closest to the present invention is a device (suspension) for the local galvanic treatment of rod de
so about yu
with
bolt-type hoists, containing a body with a hanging hook and perforated part holders, the case being designed as a vertical sheet, and part holders mounted obliquely down on each side of the case, rods are used to fix the lower edges of the part holders, while the upper edges of the part holders are rigidly connected with the body, and the vertical sheet is made in the form of a frame,
A disadvantage of this device is the low efficiency of the electroplating process, since the device does not move in the electrolyte volume, hence weak mixing, insufficient electrolyte renewal in the cathode layer and slow removal of gas bubbles from the cathode surface.
The purpose of the invention is to increase the productivity of the galvanic processing process.
The goal is achieved by the fact that a device containing a galvanic bath, a conductive rod and a hook placed on it with a perforated holder in the form of truncated cones spaced by height are fitted with a pipe mounted on a hanging hook with the possibility of rotation and a pyramidal bar with rigidly fixed frames at the bottom of the bath through the dielectric stand offset from the pipe axis, with the truncated cones of the part holder fixed on the pipe, and the end surface of the lower cone made with a bevel, and the axes of the rollers are installed in a pyramidal bar at different heights with the possibility of interaction of the lower one with the bevel of the taper holder.
FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 is a section A-A in FIG. one.
The device comprises a pipe 1 to which perforated component holder 2 is rigidly attached (for example, by means of a welded joint) in the form of several (for example, three) spaced apart truncated cones with supporting radial ribs (spokes) 3. The bottom end surface of the lower cone of the part holder has a bevel of 4 at an angle of 30-40 ° to the horizon.
In the openings of the housings of the holder 2, the machined parts 5 are located (in Fig. 1 shown as bolts).
The pipe 1 is hung rotatably on a vertical cylindrical support rod 6, the lower part of which
has a thread, and the top - hanging hook 7.
Thus, the node-holder assembly is a rigid construction of shelf type, which is hung on the rod 6.
The nut 8 is screwed on the lower part of the rod 6 to regulate the amount of penetration of the holder 2 into the galvanic
0 bath 9. The suspension hook 7 is hung on the current-carrying cathode rod 10. The latter is made with the possibility of reciprocating movement by using a motor pa gearbox together with a crank shaft mechanism (not shown).
Pipe 1 is fitted with a contact ring 11 on top of a sliding fit relative to the supporting rod 6, which provides an electrical contact for the rod - holder.
At the bottom of the electroplating bath 9 is located with a radial displacement from the center of the pipe 1 row of identical rollers 12 at different heights so that the center of the lowest roller falls on bevel 4 of the lowermost cone of the holder. The axes of the rollers 12 are installed in the sockets of the pyramidal bar 13. The latter is fixed on the dielectric stand 14 fixed on the bottom of the galvanic bath 9.
The device works as follows.
The parts 5 to be machined are inserted into the holes of the cones of the holder 2.
The support rod 6 is inserted at its lower end into the pipe 1 with the holder and the contact ring 11 and fixed
0 nut 8.
The assembled assembly 1-6-11 is hung on the lead rod 10 by means of a suspension hook 7.
At the bottom of the Eustanav5 electroplating bath, on a stand 14, a bar 13 with uneven rollers 12 is placed. At the same time, the center of the lowest roller should fall on bevel 4 of the lowermost cone of the holder. This is achieved by
0 adjusting the amount of penetration of the holder 2 into the electrolyte using a nut 8.
Then, a swing mechanism is connected to the rod 10 (the gear motor together with
5 crank mechanism). Thereby, the rod-rod-item holder is reciprocated.
When the taper 4 of the cone runs in succession on uneven rollers 12, the oscillatory movement in the vertical plane is communicated to the holder in addition to the reciprocating movement: the pipe 1 moves up and down along the rod 6 as along a guide. In addition, the point of contact of the cone of the carrier with the roller is displaced radially relative to the center of the pipe, therefore the contact force creates a moment of rotation, under the action of which the holder with the pipe rotates around rod 6. This rotation is reversible (clockwise and counterclockwise), since caused by the reverse (reciprocating) movement of the rod.
As a result, the holder holds a complex movement resulting from three component movements — reciprocating, rotating, reversing in the horizontal plane and oscillating in the vertical plane. This intensifies the mixing and renewal of the cathode electrolyte layer, accelerates the removal of gas bubbles from the cathode surface, thereby increasing the operating current density and current output, ultimately increasing the efficiency of the electroplating process.
At the end of the technological cycle, the rod 10 is disconnected from the swing mechanism and de-energized. The holder with the parts is turned over the container by the lower cone, and the parts are poured out.
