Specific embodiment
Technical solution of the present invention is further described with reference to the accompanying drawing, but claimed range is not limited to institute
It states.
It as shown in figs. 2 to 4, is Simple clamp of the invention, including the copper wire as the first conducting wire, the copper wire and cathode bar
8 are connected, and the copper wire as the second conducting wire 2 is connected with anode stub 9, and the copper wire is intertwined and connected with impressed current anode conducting wire, auxiliary sun
Polar conductor and the second conducting wire be enclosed with the first conductor combination of the first insulating layer (by second insulating layer 6 in Fig. 3, in this example
It is wound using insulating tape).
(1) material selection:
The copper wire of Φ 3mm is selected to connect as part with cathode bar 8 as the first conducting wire, the crotch section 1 of the first conducting wire
Hook;Use the stainless steel wire of Φ 2.5mm as impressed current anode conducting wire;Select the copper wire of Φ 0.5mm auxiliary as connection stainless steel wire
The conductor wire (the second conducting wire 7) of supporing yang pole and anode stub 9;Not with insulating tape insulated part copper wire (the second conducting wire 7) and part
Become rusty steel wire, and anode and cathode (i.e. the first conducting wire and the second conducting wire and impressed current anode conducting wire) is isolated.
(2) fixture production method:
The Φ 3mm copper wire of a length of 500mm is chosen according to plating liquid level and pole stick height and is fabricated to hook-shaped (one
End is crotch), for hanging over cathode bar 8, the other end is quarter bend (the right angle bending segment 2 of the first conducting wire in Fig. 3) and holds
Head is in the tilting 3 at 45 degree of angles, as the contact point with part;And got up with insulating tape by middle section insulation protection is linked up with,
The tilting 3 of quarter bend end exposes, as cathode conductiving point;According to pipe depth, the Φ 2.5mm of a length of 100mm is selected
The a length of 60mm in quarter bend one end is made in stainless steel wire, and as impressed current anode, a length of 40mm in one end connects the copper wire (the of Φ 0.5mm
Two conducting wires 7), the copper wire other end reconnects anode stub 9;(the second conducting wire 7, but its are herein referred to insulating tape insulated part copper wire
The one end connecting with anode stub 9 is not required to insulate, and needs conduction) and part stainless steel wire, and anode and cathode is isolated (i.e. using insulating tape
It snarls on the outside of the copper wire as the first conducting wire).It should be noted that second insulating layer is first when winding second insulating layer
5 height (the latter says thickness) of outer surface at conducting wire right angle bending segment right-angled corner (will tilt 3 end with exposed conductiving point
End) it keeps with high.
Such as Fig. 1, the difficult point of part is mainly that inner hole is zinc-plated, and inner hole is small, and deep.Use the stainless steel wire of Φ 2.5mm as auxiliary
Supporing yang pole uses the copper wire of Φ 3mm as the contact point with cathode, closely located, the electric current point of impressed current anode to accessory inner surface
Uniformly (see Fig. 2), then quality of coating is uniform for cloth.In the plating process, because the dress of part is hung there is no fixing, as long as gently rotating
Part is the contact position of changeable part and fixture, is operated very easy.
Before improvement, the existing every slot of fixture is only capable of plating 3, and first plating inner hole plates outer surface again, and a slot part needs
60min needs to plate 48 ÷ 3=16 slots, needs the time: 16 × 60=960min.In addition the preparation time needs whole one day.
After improvement, the every slot of fixture of the invention can plate 12, and interior exit orifice is electroplated together, and a slot part only needs 20min,
It needs to plate 48 ÷ 12=4 slots, needs 20 × 4=48min of time.
The zinc-plated Simple clamp of this conduit of the invention, can improve Uniformity of zinc coat, convenient for mounting and clamping, easy to operate,
Improve processing efficiency.
