Abstract
The utility model provides a wear -resisting tape welding connects frock, its characterized in that includes die block case, anchor clamps and die block case pillar, is middle on the die block case to be equipped with the slot hole, is equipped with the argon gas interface in one side of die block case, anchor clamps forms by anchor clamps and four clamp bolts of two couples of F shape, the last sheer pole of anchor clamps is distinguished relative centre gripping and is in the both ends of die block case about, the screw of orientation is equipped with the clamp bolt about being equipped with on the horizontal pole below each these anchor clamps in this screw. The utility model has the advantages that: leading to method that the the argon protection back of weld can not form the oxide layer through the unsettled solution back metal material of back of weld simultaneously to weld quality's influence and reaching the welding seam and once weld the shaping, the welding frock and method for that requirements for quality is all satisfied on back welding seam two sides is ground in the economy -combat. By twice weld forming of original positive and negative, optimize to once welding dual shaping and can guaranteeing the requirements for quality on two sides.
Description
Technical field
The utility model relates to a kind of wear-resistant strip welding tooling, is mainly used in clamping wear-resistant strip and welds.
Background technology
In hard rock tunnel development machine (being called for short TBM), main driving is the key equipment of this machine.Stud with one deck wear-resistant strip between main driving sealing ring and revolving body, this wear-resistant strip is import parts.Delivery state, in volume strip, will be welded into ring-type according to the concrete size of sealing station after arrival.Be specialty alloy materials due to this wear-resistant strip and be the sheeting of 1.5 ~ 2mm, need weld with argon arc welding.Prior art is argon arc welding welding by both sides, namely first welds one side, and mother metal turns over a rear polishing back side secondary welding again.This kind of welding manner mainly contains following three point defects:
1, once welding should produce thermal deformation increase secondary welding difficulty after being heated;
2, in secondary welding process, mother metal is double stands high temperature, and the crystal state that should change material weakens intensity and the wearability of material;
3, twice welding increases mother metal deflection affects inlaying sealing and reducing service life of sealing ring of wear-resistant strip and body.
Summary of the invention
The utility model aims to provide a kind of wear-resistant strip welding tooling, reaches a through welding all meet quality requirement in weld seam two sides by the method for the unsettled logical argon shield simultaneously of back of weld after polishing.
The technical solution of the utility model is: a kind of wear-resistant strip welding tooling, is characterized in that, comprises bed die case, fixture and bed die case pillar, is provided with elongated hole, is provided with argon gas interface in the side of bed die case in the middle of on bed die case; Described fixture is made up of the fixture of two pairs of F shapes and four fishbolts, the upper sheer pole of fixture is clamped in the upper and lower of the two ends of described bed die case respectively relatively, cross bar below each this fixture is provided with the screw of above-below direction, at this screw built with fishbolt.
The top of the cross bar on described fixture is provided with the clamping head of duckbill, is provided with convex dish on the top of described fishbolt.
The two rows trimming bolt corresponding with this elongated hole is housed below described bed die case.
The utility model has the advantages that: reach weld seam by the impact method that logical argon shield back of weld can not form oxide layer of back of weld unsettled solution back metal material butt welded seam quality simultaneously and be once welded into type, after polishing, weld seam two sides all meets welding tooling and the method for quality requirement.By original positive and negative twice welding fabrication, be optimized for that once to weld two sides shaping and can ensure the quality requirement on two sides.

Detailed description of the invention
See Fig. 1 ~ Fig. 5, a kind of wear-resistant strip welding tooling of the utility model, is characterized in that, comprise bed die case 1, fixture and bed die case pillar 5, be provided with elongated hole 11, be provided with argon gas interface 4 in the side of bed die case 1 in the middle of on bed die case 1; Described fixture is made up of the fixture 2 of two pairs of F shapes and four fishbolts 5, the upper sheer pole of fixture 2 is clamped in the upper and lower of the two ends of described bed die case 1 respectively relatively, cross bar below each this fixture 2 is provided with the screw of above-below direction, at this screw built with fishbolt 5.
The top of the cross bar on described fixture 2 is provided with the clamping head 21 of duckbill, is provided with convex dish 51 on the top of fishbolt 5.
The two rows trimming bolt corresponding with this elongated hole 11 3 is housed below described bed die case 1.
Using method of the present utility model: the two ends of the wear-resistant strip mother metal 6 that need dock are fixed on above bed die case 1 by fixture 2, make its abutment joint in the medium line position of the elongated hole 11 of bed die case 1, regulate fishbolt (moving up), bed die case 1 and mother metal 6 are clamped, then by the flatness that trimming bolt 3 regulates mother metal 6 to dock, trimming bolt 3 also plays a supportive role to mother metal 6 in argon arc welding process.The argon gas interface 4 of bed die case 1 is connected with argon gas source of the gas by air inlet pipe, and during welding, argon gas source of the gas passes in bed die case 1, carries out gas shield to below the mother metal 6 at elongated hole 11 place.During welding, the top of mother metal 6 is welding wire, tungsten level and argon nozzle, has argon shield below mother metal 6, thus meets and once weld the shaping and requirement of ensuring the quality of products in two sides.
