Description

The used drums for galvanic processing of parts do not provide uninterrupted transportation of parts and their mechanized unloading from the drum.

The described drum for galvanic processing of parts provides automatic movement of parts during processing and their automatic loading and unloading.

This is achieved by the fact that each section of the drum is equipped with screw blades and pockets, and for unloading parts on the same axis with the sections of the drum, repairing the external elevator.

The drum is designed for galvanic processing of small turned, stamped and other products.

The drum (see drawing) consists of a perforated case / rigidly connected to an elevator, also made in the form of a drum with a perforated case 2 and side walls 5 and 4 of non-perforated sheet material.

The drum and the elevator are seated and the common horizontal shaft b, which rotates from the drive (not shown). The shaft rotates in the bearings 6, mounted on the side of the bath 7, which is filled with an appropriate solution, penetrating the inside of the drum and the elevator through the holes in their housings.

Handle products are loaded into the drum through the hopper 8 with tray 9. The drum is divided into sections by W partitions. Screw blades // are welded to each drum section, and in the partitions there are holes with pockets 12.

The parts, moving along the tray 9 into the first compartment of the drum, move the partition 10 to the partition 10 when the drum rotates and enter the pocket 12. Then, along the inclined side wall of the drum, the parts slide into the next compartment and, moving in the same way, reach the end of the last compartment the drum, from where, through the last pocket 12, is reloaded into the elevator.

From the inner side of the elevator casing 2, buckets 13 are welded. When the elevator casing rotates, the parts caught in it are caught by the buckets and, lifting together with them, are reloaded into the receiving tray 14, from which they are automatically unloaded, shifted, and along the inclined wall under the influence of its own body.

If necessary, several drums are connected to a common line and processed products, the passage in series through them is subjected to proper treatment, for example, degreasing, washing, grass, galvanizing (chrome plating, galvanizing, etc.) and drying. The products are moved from one drum to another automatically, from the receiving tray 14 of the elevator of one drum to the hopper 8 of the next drum.

Subject invention

A drum of galvanic machining of parts with a horizontal axis mounted in bearings on the sides of the bath, driven by an electric motor, consisting of separate sections in the form of a non-perforated body with welded partitions, each of which the section is equipped with screw blades and pockets, and an external elevator is mounted for unloading parts on the same axis with drum sections.
