Description
Technical field
The present invention relates to a kind of auxiliary welding equipment, more particularly, to a kind of the auxiliary of printing plate cylinder roll bending weld seam welding
Help device and its application.
Background technology
It is typically that welding version is used as using brass bar when carrying out weld seam welding to printing plate cylinder roll bending in conventional art
The frock of roller.During welding, roller weld seam will be in close contact with copper rod, and the starting the arc one is stepped up with screw, fall arc one
Stepped up with V-type frock, but in welding process, the temperature of commissure can be up to more than 1000 DEG C, and this can cause
Copper rod temperature distortion is serious.Under normal circumstances, a copper rod will be repaired every two months, to ensure roller weld seam
It can be in close contact with copper rod, and copper rod can be repaiied thinner and thinner during repairing, in this case, a copper
The service life of rod about 2 years, and the cost for changing copper rod is higher, a copper rod is worth about 10,000 yuan.Meanwhile,
In welding process, copper rod deforms under the high temperature conditions, and this causes weld seam to produce gap with copper rod contact position,
The welding wire melted during welding is filled at gap, so as to cause roller weld joint on inner side to be uneven, after justifying through school, is held
Be also easy to produce crack, in cylindrical lathe process, can also because tube wall uneven distribution is even and caused by car leak waste product occur,
Once producing crack or car leakage, it must just re-work, this can not only can extend manufacture cycle, can also cause processing
The huge waste of cost and resource.In addition to above-mentioned technical problem, at present, the weld seam of printing plate cylinder roll bending was being welded
Cheng Zhong, also has that automaticity is low, positioning precision not enough causes welding quality defects and operating efficiency low
Problem.
Chinese patent CN 204108503U disclose a kind of device welded for printing plate cylinder roll bending weld seam, should
In the device of patent disclosure, the welding of weld seam is carried out as auxiliary mould using channel-section steel, solder flux is placed in channel-section steel,
Because being that, with solder flux and the contact of roller weld seam inwall, so higher to welding current requirements, electric current is too small, weldering in weld seam
Silk and weld seam both sides merge bad, and roller school bowlder easily produces crack；Electric current is excessive, easily causes outside weld depression,
School circle after the space of a whole page be possible to lathe car less than；Waste product is produced, need to reload and re-work, causes to waste.It is i.e. above-mentioned right
Also easy there is the underproof situation of weld seam as the technical scheme of auxiliary welding equipment using channel-section steel than patent.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind it is simple in construction,
Servicing unit and its application that printing plate cylinder roll bending weld seam that is easy to use, can adjusting is welded.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of servicing unit of printing plate cylinder roll bending weld seam welding, including a round steel, one is offered above round steel and is lacked
Mouthful, being embedded in breach along round steel axial direction in a groove profile chromium-zirconium-copper bar, described chromium-zirconium-copper bar groove is used to place
Height set screw is provided with below solder flux, described chromium-zirconium-copper bar, described height set screw is set through round steel
Put, its upper end is the contact jaw for being contacted with chromium-zirconium-copper bar, and lower end is the adjustable side outside round steel, described
Chromium-zirconium-copper bar side wall be provided with holds out against screw.
Described height set screw is along chromium-zirconium-copper bar length direction spaced set.
The side of described chromium-zirconium-copper bar abuts round steel, and opposite side is provided with holds out against screw.
Described holds out against screw is along chromium-zirconium-copper bar length direction spaced set.
Described round steel is connected with ground wire.
The application of the servicing unit of the printing plate cylinder roll bending weld seam welding, in use, described servicing unit is put
Put in printing plate cylinder roll bending, according to printing plate cylinder roll bending feature (weld seam inner side is high in the middle and low on both ends) and chromium-zirconium-copper
Bar abrasion condition, adjusts chromium-zirconium-copper bar height, it is ensured that chromium-zirconium-copper bar and printing plate cylinder roll bending by height set screw
Weld seam inwall is in close contact, and is welded from one end to the other side along chromium-zirconium-copper bar length direction using tip.Use this hair
Bright servicing unit, due to the frock by the use of chromium-zirconium-copper bar as welding, it is ensured that appropriate high welding can be used
Electric current, so that the welding wire that melts and roller weld seam both sides are fully merged during welding, and has chromium-zirconium-copper bar due to interior
In the presence of, and make outside weld without depression, simultaneously because the height of chromium-zirconium-copper bar can be adjusted, and it can be pushed up by adjusting
Tight screw, so as to ensure that chromium-zirconium-copper bar and roller weld seam inwall are in close contact.Prevent because of weld cracking and version
Face lathe car is reloaded less than the waste product caused.
Compared with prior art, the present invention has advantages below and beneficial effect：
1st, the assistant apparatus structure of printing plate cylinder roll bending weld seam welding of the present invention is simple, and service life is long.
2nd, the servicing unit of printing plate cylinder roll bending weld seam welding of the present invention is due to that can adjust the height of chromium-zirconium-copper bar
And the width dimensions of chromium-zirconium-copper bar are adjusted by holds out against screw, therefore can preferably ensure chromium-zirconium-copper bar and roller
Weld seam inwall is in close contact.Prevent the waste product because of weld cracking and space of a whole page lathe car less than caused by reload.
3rd, using technique of the common channel-section steel as auxiliary welding tool, the substandard products (crack needs to reprocess) of generation,
Waste product (Che Buqi) is more, monthly reloads 30 or so, and cost wastes big.By every material cost+artificial into
This monthly reduces in 50 yuan or so calculating and wastes 1500 yuan or so.After the servicing unit for using the present invention now,
Not only alleviate the labor intensity of workman, improve production efficiency, even more prevented that crack is reprocessed, car does not rise and reloaded
The time caused and cost are wasted.
