Description

The roller electrode assembly
Technical field
The utility model relates to a kind of excellent wire rod processing unit (plant), especially a kind of roller electrode assembly that is applicable to that a material electric plastic pulling is shaped.
Background technology
The electricity plastic working is a kind of new type of metal Technology of Plastic Processing, can effectively reduce the material deformation drag, improves material property.Electricity needs in the plastic processing high energy pulse electric current is introduced the work metal material, when material is exposed in the air and will produces spark phenomenon during with electrode loose contact.For silk material processing, some can be with the lubricated silk material of drawing oil, and general way is that electrode, mould and a silk material are together immersed in the drawing oil, enters the sparking problem that solves thereby completely cut off air.But must use the metal material of kollag for those drawing deformations, because silk material and electrode are exposed in the air, when because loose contact makes when producing the slit between a material and the electrode, pulse voltage is with the air breakdown in the slit, local sparking causes producing spark phenomenon.Be exposed to airborne sparking problem in order to solve a material and electrode, method commonly used is to become briquetting to compress a material electrode design, contacts with a silk material in the mode of sliding friction.
Be 200820227789.4 in the patent No., denomination of invention for the electric installation that adds described in " electric plasticity is hot candied with adding electric installation " Chinese patent is: a lateral electrode is connected with wire-drawing die, and the opposite side electrode is fixedlyed connected with briquetting by guide plate.Mode by sliding friction contacts with the silk material, and introduces the high energy pulse electric current.Thisly power up the loose contact that mode has been avoided electrode that mould one end causes by silk material tube reducing and silk material, the other end still contacts a material in the mode that compresses.This design has solved that some diameters are thin, intensity is lower, has been easier to the sparking problem of crooked silk material, but the silk material higher for some intensity, that diameter is thicker, because a silk material bending strength height, briquetting can not realize good hold down, sparking still happens occasionally.Owing to be the way of contact of sliding friction between electrode and the silk material, cause a material surface tear and electrode heavy wear easily simultaneously.
Summary of the invention
In order to solve the sparking problem between material in the electric plastic pulling process and the silk material, the utility model proposes a kind of roller electrode assembly.
Solve the problem that prior art exists, the technical scheme of taking of the present utility model is: the roller electrode assembly, to be formed by insulation roller core, rolling bearing, conduction roller shell, insulation barrier, L type slide block, binding post, and its conduction roller shell is arc; L type slide block and binding post are fixed on the insulation roller core; The conductive rollers cover is enclosed within the rolling bearing outside, and its edge contacts with L type slide block; L type slide block contacts with binding post, and is connected with the operate outside power supply by binding post; Be provided with insulation barrier between L type slide block and the rolling bearing.L type slide block contacts with the burnishing surface of conduction roller shell, and the contact position superficial layer has electrically conductive graphite.This electrode assembly is fixed on the diaphragm capsule of wire-drawing equipment by fixed support.
The beneficial effects of the utility model are: apparatus structure is simple; be convenient to dismounting; contact the traditional sliding-contact of replacement between electrode and the silk material to roll; can not only thoroughly solve the sparking problem in the electric plastic pulling process; simultaneously also can protect a material; avoid surface tear, and prolonged the service life of electrode.
Below in conjunction with embodiment and accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is operation principle schematic diagram of the present utility model.
Shown in the figure: fixed support 1, insulation roller core 2, rolling bearing 3, conduction roller shell 4, insulation barrier 5, L type slide block 6, binding post 7, wire-drawing die 8, silk material 9.
The specific embodiment
The utility model is a kind of roller electrode assembly of introducing pulse current in the electric plastic pulling process at the silk material, specifically comprise: fixed support 1, insulation roller core 2, rolling bearing 3, conduction roller shell 4, insulation barrier 5, L type slide block 6, binding post 7, wire-drawing die 8, silk material 9, this electrode assembly is made up of insulation roller core 2, rolling bearing 3, conduction roller shell 4, insulation barrier 5, L type slide block 6, binding post 7.
L type slide block 6 and binding post 7 all are fixed on the insulation roller core 2, conduction roller shell 4 is enclosed within rolling bearing 3 outsides, its edge contacts with L type slide block 6 in the mode of sliding friction, and L type slide block 6 contacts with binding post 7, thereby is connected the introducing pulse current with the operate outside power supply by binding post 7.Be furnished with insulation barrier 5 between L type slide block 6 and the rolling bearing 3, guaranteed that bearing is not charged, the operate as normal of bearing has been protected in not burning.A whole set of roller electrode assembly is fixed on the diaphragm capsule of wire-drawing equipment by fixed support 1.
Shown in the figure, L type slide block 6 contact conduction roller shells 4 part cross-sectional areas should be bigger, guarantee the inflow conduction roller shell 4 that electric current disperses, L type sliding 6 and the polishing of roller shell 4 contact-making surfaces process, to reduce friction, brush the electrically conductive graphite breast at contact surface and lubricate, also play secluding air simultaneously, suppress the generation of sparking.
In this electrode assembly, conduction roller shell 4 is designed to camber, be conducive to increase the contact area of conduction roller shell 4 and silk material like this, thereby avoided silk material 9 and conducted electricity having crack and producing the phenomenon of local gas disruptive discharge between the roller shell, disperseed electric current simultaneously, reduce the current density of contact-making surface, avoided a material 9 surfaces that hot-spot takes place because current density is excessive, even fusing.In addition, increase contact area and be conducive to increase frictional force between conduction roller shell and the processed silk material 9, rotate thereby make a material 9 can drive conductive rollers, make between a material 9 and the conduction roller shell 4 non-sliply, guarantee the continuation that rolling contacts.
In the electric plastic pulling process, two electrode assemblies place wire drawing die 8 two ends respectively, make electric current in drawing process, flow through a material 9 and by mould 8 the plastic deformation part takes place, in the electric plastic pulling process, should guarantee that the electric current incoming direction is consistent with silk material 9 drawing directions, improve electric plasticity effect to greatest extent.
