Abstract
A kind of electroslag welding spark blowout, it comprises two identical blow-out copper billets (1), described blow-out copper billet (1) is cuboid, medial surface has arc groove (11), the arc groove (11) of described two blow-out copper billets (1) encloses a full circle, the inner side outer edge of described blow-out copper billet (1) is provided with bolt part plate (12), and described two blow-out copper billets (1) are connected and fixed by the bolt (13) on bolt part plate (12).The utility model changes traditional spark blowout, adopt two striking copper billet docking to enclose composition, spark blowout can very easily be departed from from filling between metal and slag, even if blow-out copper billet has slight deformation in use, also its secondary that affects that can be not excessive uses, extend life cycle, saved production cost.
Description
Technical field
The utility model relates to a kind of box electroslag welding welding tooling of manufacture of steel structure manufacture field, and more particularly it is a kind of electroslag welding spark blowout.
Background technology
Electroslag welding is to utilize electric current to pass through resistance heat that slag produces as thermal source, will fill metal and mother metal fusing, forms metal and be connected with mother metal after solidification and crystallization.Form molten bath by full whole welding bead weldering by continuous wire feed.Because electroslag welding also has the solder flux liquation of certain altitude when the blow-out in welding bead, and if be soldered to terminal molten bath and air contact area and increase that to cause the words of the unstable direct blow-out in welding bead of current/voltage will be easy to form welding bead incompletely filling.Therefore need to add an electric arc ejector in the terminal of electroslag welding and make its blow-out outside formal welding bead, initiating terminal needs too to add an arc initiation device and weld seam is introduced to formal welding bead blow-out is not described further herein.
Now, in construction steel structure, electroslag welding is mainly used in the welding of box-type member internal partition, and the concrete form quality of the striking to electroslag welding in GB and spark blowout does not have detail requirement.In industry, spark blowout generally adopts the form of ring seal cover made of copper.This kind of mode defect is more obvious, because easily making blow-out copper sheathing, the filling metal of drawing from welding bead and high-temperature slag produce distortion, make blow-out copper sheathing and fill between metal and slag to be difficult to depart from, have a strong impact on the effect of recycling, shortened life cycle and increased production cost.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned existing background technology, and provide a kind of electroslag welding spark blowout, spark blowout can simply be departed from from filling between metal and slag, and increase the service life of drawing spark blowout, reduce production costs.
The purpose of this utility model reaches by following measure: electroslag welding spark blowout, its special character is, it comprises two identical blow-out copper billets, described blow-out copper billet is cuboid, medial surface has arc groove, the arc groove of described two blow-out copper billets encloses a full circle, and the inner side outer edge of described blow-out copper billet is provided with bolt part plate, and described two blow-out copper billets are connected and fixed by the bolt on bolt part plate.
In technique scheme, the thickness of described blow-out copper billet is not less than 60mm.In order to ensure that weld metal has the suitable length of drawing, the thickness of blow-out copper billet should be not less than 60mm, to improve the quality of weld seam.
The utlity model has following advantage: efficiently solve filling metal that electroslag welding draws from welding bead and high-temperature slag and make blow-out copper sheathing and fill between metal and slag, to be difficult to the problem that departs from, ensure the quality of formal weld seam, the first-time qualification rate of product is improved greatly; The utility model changes traditional spark blowout, adopt two striking copper billet docking to enclose composition, spark blowout can very easily be departed from from filling between metal and slag, even if blow-out copper billet has slight deformation in use, also its secondary that affects that can be not excessive uses, extend life cycle, saved production cost.

Detailed description of the invention
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Simultaneously by illustrating that advantage of the present utility model will become more clear and easily understand.
Consult Fig. 1 to Fig. 4 known: the utility model electroslag welding spark blowout, it comprises two identical blow-out copper billets 1, blow-out copper billet 1 is cuboid brass ingot, its medial surface has arc groove 11, the arc groove 11 of two blow-out copper billets 1 encloses a full circle, the inner side outer edge of blow-out copper billet 1 is provided with 12, two blow-out copper billets 1 of bolt part plate and is connected and fixed by the bolt 13 on bolt part plate 12.
Implementation process of the present utility model is: first box 2 to be welded is placed on moulding bed, electroslag welding hole 21 peripheries are cleaned out.Again arc initiation device 31 is put in to electroslag welding hole 21 lower ends, after package unit centring, holds out against with jack 32.Then two blow-out copper billets 1 are combined with bolt 13 and fixed, be placed on electroslag welding hole 21 tops, the arc groove 11 at two blow-out copper billet 1 centers encloses molten bath.
Welding gun 3 is inserted from electroslag welding hole 21 in the striking groove of spark blowout 31 of welding bead bottom.Then start electroslag welder, the electric arc that ignites, after flux melts, forms slag.In welding process, according to the suitable adjusting fusing mouth of panel color or the locus of welding gun 3, make it in centre, molten bath.When welding proceeds to while drawing the stage, should not bleed off at once slag 4, and should ensure that weld metal 5 has the suitable length (as shown in Figure 4) of drawing, and unclamps bolt 13 and takes off respectively two striking copper billets 1, after weld seam is cooling, by smooth the reconditioning of welding bead terminal.
For box 2 deformation extents are obtained unanimously, must be to be symmetrically welded under normal circumstances, adopt the both sides welding bead of two electroslag welders to internal partition for this reason, weld simultaneously.
Other unspecified part all belongs to prior art.
