Abstract
The utility model relates to a sealing ring of a precise vacuum fitting-welding mould of a thin plate, which belongs to the field of welding and setting equipment. A mould is composed of a mould main body, an inserting block and an end cover. A plurality of grooves for ventilating and placing a thin-plate precise vacuum fitting-welding mould of the sealing ring are made on the mould main body and the inserting block. The sealing ring is a hollow sealing ring. A vacuum fitting-welding mould of the utility model is adopted, which makes a workpiece is tightly pasted on a mould when the workpiece of the thin plate is fitted and welded. A welding position is not provided with a clamp which prevent from carrying out welding, which makes welding work smoothly carried out and the workpiece conveniently taken and unloaded.
Description
The utility model relates to the dress weldering mold of thin plate, belongs to weldering and establishes the equipment field.
Assembling, the welding of thin plate (ferrous metal or non-ferrous metal) can run into more difficulty in welding is produced, the mechanical hold-down mechanism of the many employings of mount method commonly used, all be that pressurization is fixed on the mold whole work-piece in the local area, but because the rigidity of thin plate is less, easy deformation, especially in welding process because the effect of welding stress can make workpiece produce very big distortion, cause profile defectives such as waveform.In order to guarantee assembly quality, will a plurality of pressure heads be set near the commissure, this can influence the carrying out of welding job, just makes to guarantee assembly quality, welds easily again and has produced contradiction.Chinese patent CN97202756.4, denomination of invention provides the accurate vacuum dress of a kind of thin plate weldering mold for the utility model patent of " the accurate vacuum of thin plate is adorned the weldering mold ", and this mold is made up of mold main body, insertion piece and end cap.Workpiece is close to the mold periphery; on mold main body and insertion piece, make a plurality of grooves to form the vacuum space; the groove that feeds protective gas is made at the weld seam position place that is positioned on the welding work pieces on mold main body and insertion piece; in the groove both sides seal washer groove is arranged, to lay seal washer.On end cap, there are vacuumizing joint and protective gas to feed joint; in the protective gas groove, feed protective gas; make welded seam area form a protective gas district, but in welding process, often cause weld seam weldering leakage because of the seal washer poor sealing makes near the weld seam protective gas district communicate with vacuum area.
The purpose of this utility model provides and a kind ofly can guarantee assembly quality, can guarantee the gastight sealing ring in protective gas zone again.
Sealing ring of the present utility model is a circular hollow sealing strip, is installed in the o-ring groove of mold.
Illustrate that accompanying drawing is as follows:
Fig. 1 is a hollow seal circle profile.
Accompanying drawings embodiment is as follows:
Dress weldering vacuum mold is a combination mold, is made up of mold main body, insertion piece and end cap.Workpiece is close to the mold periphery; on mold main body and insertion piece, make a plurality of grooves to form the vacuum space; the groove that feeds protective gas is made at the weld seam position place that is positioned on the welding work pieces on mold main body and insertion piece; in the groove both sides o-ring groove is arranged, to lay the hollow seal circle.On end cap, there are vacuumizing joint and protective gas to feed joint.Mold main body and insertion piece are combined into a complete mold during use, the workpiece of welding is close to the periphery of mold, load onto end cap, start vavuum pump, bleed, groove between mold and the workpiece promptly forms vacuum (vacuum is 0.5 * 10-1 torr), because the pressure of atmosphere can closely be pressed on welding work pieces on the mold.
Adopt the utility model vacuum dress weldering mold when dress weldering thin plate workpiece workpiece is attached on the mold closely, the jig that does not hinder welding to carry out in the commissure can make welding job carry out smoothly, and unloading workpiece easily.
