A Simple Fixture for Conduit Galvanized

Abstract

The invention discloses a simple fixture for galvanizing a guide tube. The simple fixture comprises a first conducting wire, a second conducting wire and an auxiliary anode conducting wire, wherein the first conducting wire is connected with a cathode bar, the second conducting wire is connected with an anode bar, and the auxiliary anode conducting wire is connected with the second conducting wire; a hook section is formed on one end, which is connected with the cathode bar, of the first conducting wire, a right-angle bending section is formed on the other end of the first conducting wire, an upwarp is formed on the tail end of the right-angle bending section, and a first insulating layer is arranged on the outer side of the first conducting wire between the upwarp and the hook section; and the auxiliary anode conducting wire is in a right-angle bending shape and is connected with the right-angle bending section of the first conducting wire by virtue of a second insulating layer. The simple fixture has the advantages of simplicity, easiness in manufacturing, good conduction, simplicity and convenience in hanging and installation and simplicity in operation. The simple fixture is mainly composed of a stainless steel wire, a copper wire and an insulated rubber tape, and an auxiliary anode can be arranged just in the middle of an inner hole of the guide tube, so that the current distribution is uniform, and the coating quality is good. The inner hole and the outer surface are electroplated once, so that the coating uniformity is guaranteed, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a clamp for integrally galvanizing the inner and outer surfaces of a conduit, and belongs to the technical field of metal material surface treatment. Background technique [0002] A part conduit (see figure 1 ), the material is carbon steel, the inner and outer surfaces are required to be galvanized as a whole, and the thickness of the coating is required to be 5-8 μm. The galvanizing method used is the cyanide galvanizing method. The pipe hole is small and deep. For deep holes, it is difficult to obtain a uniform galvanized layer. [0003] The old fixture used in the prior art is characterized by first plating the inner surface of the conduit, and then plating the outer surface of the conduit. Only 3 parts can be plated in each slot, and the efficiency is low; because in the electroplating process, the contact position between the fixture and the parts must be constantly replaced , so as not to produce fixture marks, and the...

Problems solved by technology

[0003] The old fixture used in the prior art is characterized by first plating the inner surface of the conduit, and then plating the outer surface of the conduit. Only 3 parts can be plated in each slot, and the efficiency is low; because in the electroplating process, the contact position between the fixture and the parts must be constantly replaced , so as not to produce fixture marks, and the old fixture is a fixed electroplating, so when the electroplating process changes the contact position, the operator has the risk of electric shock; due to the aging of the old fixture, there are problems such as poor contact and inconvenient clamping
