Hanging device for alternate operation of multiple process grooves and water washing grooves

Abstract

The invention discloses a hanging device for alternate operation of multiple process grooves and water washing grooves. The hanging device comprises a support and hanging assemblies, wherein each setof hanging assemblies comprises a fixed cross rod located above and a movable cross rod located below, each movable cross rod is slidably matched in an up-down sliding structure fixed on the corresponding fixed cross rod, and two ends of the fixed cross rod and two ends of the movable cross rod of each set of hanging assemblies are supported on two first straight beams of the support through respective support seats; a water washing tank movable cross rod support seat and a water washing tank fixed cross rod support seat above each water washing tank are provided with structures for bringing the corresponding movable cross rod to close to the corresponding fixed cross rod so as to change a to-be-cleaned workpiece from a first hanging part to a second hanging part; and the movable cross rodsupport seat above each process groove is connected with a driving device which enables the movable cross rod to slide up and down intermittently so as to make the workpiece be alternately switched on the first hanging part and the second hanging part. According to the hanging device, a part where the workpiece is in contact with a hanging point is cleaned up, a plating mark is prevent from leaving on the workpiece, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of chemical surface treatment equipment for workpieces, in particular to a hanging device for the alternate operation of multiple process tanks and water washing tanks. Background technique [0002] Hanging the workpiece with a hanging device in the process tank, such as alkali cleaning tank, pickling tank, chemical plating tank or chemical throwing tank, etc., is widely used for workpiece surface treatment. For example, multiple process tanks and water washing tanks are arranged in parallel. Workpieces such as cable bridges and similar workpieces often have to go through multiple degreasing and derusting process tanks, water washing tanks, chemical plating tanks, etc. for multiple rotations one by one. Alkaline washing tanks, water washing tanks, pickling tanks, water washing tanks, chemical plating tanks for rust removal...Hanging up and down, so that after multiple surface treatments such as degreasing, r...

Problems solved by technology

[0003] But the hanging device of the prior art also has the following disadvantages: after the hanging device puts the workpiece into the process tank for degreasing and derusting, the parts of the workpiece that are in contact with the hanging point cannot be removed cleanly, leaving quality hidden dangers for the next step of chemical plating, etc. When washing in the washing tank, the position of the hanging point cannot be cleaned; after the hanging device puts the workpiece into the chemical plating tank, such as static chemical plating, electroplating, etc., the parts of the workpiece that are in contact with the hanging point cannot avoid leaving hanging marks , and the surface coating is uneven, but if it moves up and down, a single plating tank is equipped with an up and down intermittent moving device, then its structure is complicated, the consumables are large, the power consumption is large, and the equipment failure rate is relatively high. It is a hanging device for the rotation of multiple plating tanks and washing tanks, which avoids hanging marks on the workpiece and makes the surface coating uniform during the electroplating process, and has a simple structure, less consumables, relatively small power consumption and low failure rate.
