Abstract
A kind of composite electric regulation pipe comprises copper pipe and steel core, and steel core tightly is placed in the copper pipe, also closely is socketed with two in the copper pipe and seals copper billet, seals the two ends that copper billet lays respectively at described copper pipe, describedly seals copper billet and described steel core is close to.Its production comprises the following steps: (1). with an end closure of copper pipe, will seal copper billet and steel core again and pack at interval in the copper pipe; (2). use drawing machine to vise the sealing end of copper pipe, make copper pipe pass through a mould, this mould has the passage that passes through for described copper pipe, produces viscous deformation by the copper pipe behind the mould; (3). copper pipe produces recess by behind the mould on the copper pipe, at recess copper pipe is cut, to obtain single composite electric regulation pipe.Beneficial effect of the present invention is: seal copper billet steel core is formed protection, so steel core is not vulnerable to extraneous corrosion.And composite electric regulation pipe press working production method provided by the present invention has realized many continuous production, the work efficiency height.
Description
(1) technical field
The present invention relates to a kind of production method of composite electric regulation pipe.
(2) background technology
Electric regulation pipe is a kind of conduction bar that is used on the electrolyzer, electric regulation pipe is erected on the busbar of electrolyzer during use, plays the effect of conduction, and hangs up various suspension members (negative electrode or anode) on electric regulation pipe.
Mostly the electric regulation pipe that the current electrolysis industry is used is simple steel bar or simple copper tubing.But simple rod iron is poor electric conductivity not only, and corrosion resistance nature is also very poor; Though and simple copper pipe electric conductivity height, corrosion resistance nature, but its load-bearing property and elastic deformation recoverability are relatively poor, and deformation was more serious after duration of service was long slightly, might influence whole electrolytic process, the big electric current softening power of particularly anti-instantaneous short circuit is poor.
At simple steel bar or the simple made existing shortcoming of electric regulation pipe of copper tubing, also the someone has proposed the composition metal current conducting rod, as the patent No. is that China of 02209925.5 uses novel patent to disclose a kind of composition metal current conducting rod, comprise copper pipe and closely be socketed in steel core in the copper pipe, and steel core and copper pipe are isometric.Outer field copper pipe has good electrical conductivity, is wrapped in the bearing that the interior steel core of copper pipe can improve current conducting rod greatly.But the steel core that is wrapped in the steel pipe is easy to produce corrosion in the end under electrolytic mal-condition, and corrosive fluid flows into electrolyzer, electrolytic solution is produced pollute, thereby influences the electrolytic production quality and can increase the workload of tank liquor cleaning section, influences the electrolysis process.
In addition, existing composite electric regulation pipe, its production method mostly is single production, and the production work efficiency is low.
(3) summary of the invention
Subject to the corrosive deficiency in order to overcome composite electric regulation pipe steel core of the prior art, the invention provides a kind of steel core and be not subject to the corrosive composite electric regulation pipe, and the production method of this composite electric regulation pipe is provided, can realize many continuous production, the work efficiency height.
The technical solution adopted for the present invention to solve the technical problems is: a kind of composite electric regulation pipe, comprise copper pipe and steel core, described steel core tightly is placed in the described copper pipe, also closely be socketed with two in the described copper pipe and seal copper billet, describedly seal the two ends that copper billet lays respectively at described copper pipe, describedly seal copper billet and described steel core is close to.
Further, the cross section of described copper pipe and steel core is rectangle.
The method of aforementioned composite electric regulation pipe comprises the following steps:
(1). with an end closure of copper pipe, will seal copper billet and steel core again and pack at interval in the copper pipe;
(2). use drawing machine to vise the sealing end of copper pipe, make copper pipe pass through a mould, this mould has the passage that passes through for described copper pipe, the front portion of described passage is the portion of expanding, the rear portion carries out the transition to contraction flow region gradually, so that copper pipe admission passage smoothly, the copper pipe of the size of described contraction flow region less than the size of described copper pipe so that by passage produces viscous deformation to described size of expanding portion greater than the size of described copper pipe;
(3). copper pipe produces recess by behind the mould on the copper pipe, at recess copper pipe is cut, to obtain single composite electric regulation pipe.Recess promptly is to seal the residing position of copper billet, and the reason that produces depression is: with respect to steel, the rigidity of copper is much smaller, therefore by behind the passage of mould, seals the residing position of copper billet and can produce bigger viscous deformation comparatively speaking.
Beneficial effect of the present invention is: be provided with in the both sides of steel core and seal copper billet, seal copper billet steel core is formed protection, so steel core is not vulnerable to extraneous corrosion.And composite electric regulation pipe press working production method provided by the present invention has realized many continuous production, the work efficiency height.

Fig. 1 is the structural representation of composite electric regulation pipe.
Fig. 2 is the production technique figure of composite electric regulation pipe.
Fig. 3 is the structural representation of mould.
Fig. 4 is by sealing the partial enlarged drawing at copper billet position behind the mould.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described.
With reference to Fig. 1, a kind of composite electric regulation pipe comprises copper pipe 1 and steel core 2, and the cross section of copper pipe 1 and steel core 2 is rectangle.Described steel core 2 tightly is placed in the described copper pipe 1, steel core 2 and copper pipe 1 shrink-fit.Also closely be socketed with two in the copper pipe 1 and seal 3, two of copper billets and seal the two ends that copper billet 3 lays respectively at described copper pipe 1, and be close to described steel core 2, two seal copper billet 3 also with copper pipe 1 shrink-fit.
With reference to Fig. 2, Fig. 3, Fig. 4, the production method of aforementioned composite electric regulation pipe comprises the following steps:
(1). with an end closure of copper pipe 1, will seal copper billet 3 and steel core 2 again and pack at interval in the copper pipe 1;
(2). use drawing machine to vise the sealing end 4 of copper pipe, make copper pipe 1 by a mould 5, this mould 5 has the passage 6 that passes through for described copper pipe 1, the front portion of described passage is the portion of expanding, the rear portion carries out the transition to contraction flow region gradually, so that copper pipe admission passage smoothly, the copper pipe of the size of described contraction flow region less than the size of described copper pipe 1 so that by passage produces viscous deformation to described size of expanding portion greater than the size of described copper pipe 1;
(3). copper pipe 1 produces recess 7 by behind the mould 5 on the copper pipe 1, at recess 7 copper pipe 1 is cut, to obtain single composite electric regulation pipe.Recess 7 promptly is to seal copper billet 3 residing positions, and the reason that produces depression is: with respect to steel, the rigidity of copper is much smaller, therefore by behind the passage of mould, seals the residing position of copper billet and can produce bigger viscous deformation comparatively speaking.
Adopt this method to produce, one-off drawing can be made many composite electric regulation pipes, and work efficiency is produced high a lot than single.
