Description
Technical field
The utility model relates to a kind of strip device, relates in particular to the quick strip device that a kind of colorful visualization tube glass cone compacting convex mould surface scribbles wolfram varbide plasma supercoat.
Background technology
At present, the glass-vacuum tube of colour television set picture tube (glass bulb) has three composed components basically, that is: the glass of fluoroscopy images shields, shields glass awl that is connected and the tubular neck portions that is communicated with the summit of glass awl with glass.The glass awl is to cooperate compacting to form by awl punch, prod cast circle, awl die.In pressing process, because the awl punch will be pressed into about 600 ℃ of pyritous glass melts glass bulb awl, so require the awl convex mould surface must have high temperature resistant, anti-grinding, corrosion-resistant, performance such as surface property is stable.Colored bulb is made the field, in order to improve the hardness and the wear resisting property of awl convex mould surface, prolongs the work-ing life of mould, all will carry out plasma spraying wolfram varbide Stainless Steel Alloy supercoat to the awl convex mould surface.But the wolfram varbide of awl convex mould surface is in use for some time plasma-coated, needs the awl convex mould surface to carry out the wolfram varbide plasma spraying again, is needing the original coating of awl convex mould surface is carried out the strip processing before the spraying again.Because the negative plate of the plasma-coated processing unit of tradition stripping wolfram varbide is fixed on around the strip groove, constitute by many sections curves as anodic awl convex mould surface, awl punch deflection position, the microcephaly position is far away than body apart from anode, this just makes the non-uniform electric of strip cell body inside, distribution of current difference between the anode and cathode is also very big, make the near awl body of negative electrode (around the strip cell body) and anode (awl punch) distance move back clean and awl punch deflection position that distance is far away, the microcephaly position is but also surplus coating, do not move back clean, especially for big specification (25 "; 27 ", 29 "; 33 ", 34 " awl punch etc.), awl punch deflection position; the wolfram varbide at microcephaly position is plasma-coated just to be difficult to move back totally more.Therefore in the plasma-coated process of traditional technology stripping wolfram varbide, because the layout of negative electrode is unreasonable, caused that stripping wolfram varbide plasma-coated overlong time, wolfram varbide are plasma-coated to move back some strip defectives such as unclean, therefore strip or prolongation strip time are satisfied production requirement again, strengthened workload, produce needs for satisfying, enhance productivity, need transform traditional withdrawal plating.
Summary of the invention
The purpose of this utility model is to overcome the quick strip device that has deficiency in the prior art and the wolfram varbide plasma supercoat that a kind of strip speed is fast, production efficiency is high is provided.
The purpose of this utility model is achieved in that the anode thick stick that has the power anode conduction function when comprising strip, fix and position the suspender of awl punch, connect binding bolt between suspender and the awl punch, rise between suspender and the awl punch conduct electricity linkage function cover plate, bore punch, be connected the negative plate of auxiliary cathode as anodic, the awl punch is placed in the plasma-coated auxiliary cathode of the wolfram varbide that has on the quick stripping awl punch, and is at regular intervals between the two.The auxiliary cathode of this quick strip device is a kind of and awl punch shape similar copying device, distance between awl punch and the auxiliary cathode can be adjusted between 10～30 millimeters, the auxiliary cathode material is the reticulated structure that is welded by stainless steel, is fit to 14 " to 34 " and has the plasma-coated awl punch of wolfram varbide.
The utlity model has following positively effect: adopt this novel plasma-coated quick strip device of wolfram varbide, overcome the slow-footed shortcoming of strip of original strip device, strip speed doubled than in the past.Owing to realized the spacing evenly (bore each point on the punch matrix and the distance of following an example between the negative electrode corresponding points reaches unanimity substantially) between auxiliary cathode and the anode (awl punch); distribution of current is reasonable; make the whole strip speed of cathode-ray tube glass cone compacting convex mould surface reach consistent substantially; improved the plasma-coated bulk velocity of strip wolfram varbide; shortened the whole strip plasma-coated whole time of wolfram varbide of awl punch; improve production efficiency, satisfied the production needs.
