Description

A kind of zinc-plated Simple clamp of conduit

Technical field

The present invention relates to a kind of overall zinc-plated fixture of conduit surfaces externally and internally, belong to metallic material surface treatment technology neck Domain.

Background technology

Certain part conduit (see Fig. 1), material is carbon steel, it is desirable to which surfaces externally and internally is integrally zinc-plated, thickness of coating requirement：5~8 μ M, used galvanized method are cyanide zinc plating wastewater method, and the caliber of the conduit is Φ 10mm, tube length 60mm, because of the pipe hole It is smaller and relatively deep, for deep hole, it is larger to obtain uniformity zinc coat difficulty.

The old feature of jigs used in the prior art is first to plate catheter inside surface, then plates catheter outer surface, per groove part only It can plate 3, it is less efficient；Because in electroplating process, constantly to change the contact position of fixture and part, in order to avoid produce fixture Print, and old fixture is fixed plating, so when electroplating process changes replacing contact position, operator has the risk being electrically shocked； Because of old fixture aging, there is the problems such as loose contact, clamping inconvenience.

The content of the invention

The technical problem to be solved in the present invention is：There is provided a kind of conduit zinc-plated Simple clamp, improve the zinc-plated work of conduit Make efficiency, and uniform zinc coat can be obtained.

Technical scheme is as follows：

A kind of zinc-plated Simple clamp of conduit, including the first wire being connected with cathode bar, second to be connected with anode stub Wire, and the impressed current anode wire being connected with the second wire；In use, the first wire and impressed current anode wire are placed in conduit Kong Zhong；

First wire and cathode bar connected end are crotch section, and the other end of the first wire is right angle bending segment, right angle There is a tilting end of bending segment, and it is the first insulating barrier to tilt on the outside of the first wire between crotch section；The impressed current anode The rectangular bending of wire, and be connected by the second insulating barrier with the first wire right angle bending segment.

With being bonded at the right-angled corner of impressed current anode wire at the right-angled corner of the first wire right angle bending segment, and it is auxiliary Supporing yang polar conductor is below the first wire right angle bending segment.That is impressed current anode wire and the first wire is tied at right-angled corner Close.

The end that the impressed current anode wire is located at guide pipe inner hole part is longer than the first wire and is located at guide pipe inner hole terminal part Point.

Outer surface of second insulating barrier at the first wire right angle bending segment right-angled corner is contour with tilting end.This Sample one may insure the diameter parallel of the impressed current anode wire of fixture and guide pipe inner hole or overlap, to inside pipe wall each point apart from base This is equal.

First wire and the second wire are copper cash.

The impressed current anode wire is stainless steel wire.

The tilting and the angle degree of being of the right angle bending segment end of the first wire.

First insulating barrier and the second insulating barrier are insulating tape.

The present invention devises a kind of Simple clamp, can improve plating according to part shape, electroplating principle, electric current issue analysis Even zinc layer, convenient mounting and clamping is simple to operate, also improves processing efficiency.

Compared with existing, advantages of the present invention is as follows：

(1) fixture is simply easily made：Mainly by stainless steel wire, copper cash and insulating tape composition.

(2) it is ingenious in design：Contacted by the use of stainless steel wire as endoporus impressed current anode and exposed copper cash with inner bore of part, as Conductiving point, solve conductivity issues.Impressed current anode may be at guide pipe inner hole centre position, homogeneous current distribution, coating matter just Measure.

(3) endoporus and outer surface are disposably electroplated, and ensure coating uniformity, and greatly improve production efficiency.

(4) fixture well conducting, dress hangs simplicity, simple to operate.

Embodiment

Technical scheme is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to institute State.

As shown in figs. 2 to 4, it is the Simple clamp of the present invention, including the copper cash as the first wire, the copper cash and cathode bar 8 are connected, and the copper cash as the second wire 2 is connected with anode stub 9, and the copper cash is intertwined and connected with impressed current anode wire, auxiliary sun Polar conductor and the second wire and the first conductor combination of the first insulating barrier is enclosed with (by the second insulating barrier 6 in Fig. 3, in this example Wound using insulating tape).

(1) material selection：

From Φ 3mm copper cash as the first wire, what the crotch section 1 of the first wire was connected as part with cathode bar 8 Hook；Impressed current anode wire is used as by the use of Φ 2.5mm stainless steel wire；It is auxiliary as connection stainless steel wire from Φ 0.5mm copper cash The conductor wire of supporing yang pole and anode stub 9 (the second wire 7)；With insulating tape insulated part copper cash (the second wire 7) and part not Become rusty steel wire, and isolates anode and cathode (i.e. the first wire and the second wire and impressed current anode wire).

(2) fixture preparation method：

A length of 500mm Φ 3mm copper cash is highly chosen according to plating liquid level and pole rod and is fabricated to hook-shaped (one Hold as crotch), for hanging over cathode bar 8, the other end is quarter bend (the right angle bending segment 2 of the first wire in Fig. 3) and held Head is in the tilting 3 at 45 degree of angles, as the contact point with part；And got up with insulating tape by center section insulation protection is linked up with, The tilting 3 of quarter bend termination, which exposes, to be come, as negative electrode conductiving point；According to pipe depth, from a length of 100mm Φ 2.5mm The a length of 60mm in quarter bend one end is made in stainless steel wire, as impressed current anode, a length of 40mm in one end, connection Φ 0.5mm copper cash (the Two wires 7), the copper cash other end reconnects anode stub 9；(the second wire 7, but its are herein referred to insulating tape insulated part copper cash The one end being connected with anode stub 9 is not required to insulate, and needs conduction) and part stainless steel wire, and isolate anode and cathode (i.e. using insulating tape Snarl on the outside of the copper cash as the first wire).It should be noted that when winding the second insulating barrier, the second insulating barrier is first The height of outer surface 5 (the latter says thickness) at wire right angle bending segment right-angled corner (will tilt 3 end with exposed conductiving point End) keep with high.

Such as Fig. 1, the difficult point of part is mainly that endoporus is zinc-plated, and endoporus is small, and deep.By the use of Φ 2.5mm stainless steel wire as auxiliary Supporing yang pole, the contact point with negative electrode, closely located, the electric current point of impressed current anode to accessory inner surface are used as by the use of Φ 3mm copper cash Uniformly (see Fig. 2), then quality of coating is uniform for cloth.In electroplating process, hang because of the dress of part and do not fix, as long as gently rotating Part can change the contact position of part and fixture, and operation is very easy.

Before improvement, existing fixture is only capable of plating 3 per groove, and first plating endoporus plates outer surface again, and a groove part needs 60min is, it is necessary to plate 48 ÷ 3=16 grooves, it is necessary to the time：16 × 60=960min.Needed whole one day plus the preparation time.

After improvement, fixture of the invention can plate 12 per groove, and interior exit orifice is electroplated together, and a groove part only needs 20min, Need to plate 48 ÷ 12=4 grooves, it is necessary to 20 × 4=48min of time.

The zinc-plated Simple clamp of this conduit of the present invention, can improve Uniformity of zinc coat, and convenient mounting and clamping is simple to operate, Improve processing efficiency.
