The cross section of the plasma-arc of the plasma-arc welding that the single rifle of existing utilization carries out is the summary circle.If thickness of slab less than 3mm, then can not carry out the aperture welding through plasma-arc, therefore; Kiss welding (heat-conduction-type welding) is touched in employing, still, even touch the kiss welding; Also when changing at a high speed, undercutting takes place easily and the high temperature that causes owing to the wide cut bead breaks.When high-speed welding, electric current becomes wide cut electric arc because of high electric current, therefore, becomes the shallow bead shape of fusing into of wide cut, when solidifying, high temperature takes place easily break.
In the welding of plasma-arc that the single rifle of existing utilization carries out, when the thickness of slab with 3～10mm made aperture welding high-speedization, the bead shape can become the convex form that central portion swells and therefore the undercutting of edge part decline, is not easy to change at a high speed.High-speedization that the single molten bath of being undertaken by 2 rifles is also arranged, still, in order to become single molten bath; Therefore, rifle must tilt each other significantly, attaches because the arc force of mutual drawing blows with the magnetic that tilts to cause; And electric arc is at random easily, becomes unstable.
So the inventor etc. provide a kind of and can realize not having high temperature with stable electric arc and break and the plug-in type chip of the high-speed welding of undercutting and the plasma gun (patent documentation 5) that uses this plug-in type chip.
Specifically; The plug-in type chip comprises: two electrode configuration spaces and be distributed on the same diameter line and be communicated with to come two nozzles relatively offering with the sealing wire that is parallel to above-mentioned diameter line, plasma gun to be equiped with this chip respectively with each electrode configuration space and in each electrode configuration space, insert each electrode.
According to the plasma gun that is equiped with this plug-in type chip, can carry out forming the welding of two electric arcs in single molten bath of a molten metal bath with two electric arcs.The cross section of plasma-arc becomes at welding travel direction (y) goes up elongated thermal source, therefore, is suppressed narrowlyer with respect to the bead fabric width (x direction) of heat, even high-speedization high temperature can not take place yet break.In addition, can make surperficial bead become smooth through becoming two electric arcs in single molten bath.Though can leave the synchronous welding of two plasma guns of distance to a certain degree through use, obtain roughly similar effects; Electric arc on the welding travel direction broadens at interval; Therefore, if the workpiece (mother metal: the welding object material), then can not carry out welding of short weld length at same passage; Need two channel welds, be not easy to change at a high speed.In addition, electric arc broadens at interval, and therefore, electric arc fusion once again once cakey bead in back needs high heat for the back welding.Use according to prompting in patent documentation 5 comprises two arc weldings in single molten bath of the plug-in type chip of two nozzles at 1 chip, nozzle shortens at interval, therefore, can solve these problems of elimination.
But in the plasma welding of two electric arcs of a plug-in type chip, the thermic load that puts on the plug-in type chip becomes big.In order more effectively to change at a high speed, need to improve the cooling capacity of plug-in type chip.
Therefore, inventor waits and to provide a kind of and can not have high temperature more at high speed with stable electric arc and break and the welding of undercutting and the plug-in type chip (patent documentation 6) of high cooling capacity.This plug-in type chip comprises: two electrode configuration space, two nozzles that are communicated with each electrode configuration space respectively and the plane that is in respect to distribute these two nozzles at the intermediate point of these two nozzles are the turn back V-type cooling water stream of cooling water of the plane that intersects.By this, near chip front end face (mother metal subtend face), the cooling water of turning back swimmingly, not occluded water or bubble partly, thus the cooling capacity of chip is uprised.Through to carry out perforate, can form V-type cooling water stream cheaply with respect to the form of die terminals face tilt and leading section intersection.So, can increase weld power and weld more at high speed.In addition, in patent documentation 6, also pointed out the plug-in type chip that can freely combine a pair of nozzle arrangement in chip basal body with loading and unloading.By this, can when making nozzle segment distortion or the melting loss of nozzle arrangement lower end owing to Gao Re, replace this nozzle arrangement with new product, chip basal body is still used on former state ground, thereby makes the maintenance cost become cheap.
Summary of the invention
The present invention relates to a kind of improvement that a plurality of nozzle arrangements can be incorporated into with freely loading and unloading the plug-in type chip of a chip basal body; First purpose is to improve the cooling capacity of each nozzle arrangement; It is multiple that second purpose is that the pointing direction with nozzle is set at, and the 3rd purpose is to carry out behind the pointing direction of regulation nozzle combining with respect to chip basal body the operation of nozzle arrangement easily and simply.
Technical scheme 1: a kind of plug-in type chip comprises: and a plurality of nozzle arrangements (20a, 20b), these a plurality of nozzle arrangement (20a; 20b) have central authorities offer nozzle (3a, umbrella portion 3b) (21a, 21b), with continuous bar portion of this umbrella portion (22a, 22b) and with the continuous outer screw section (24a of this bar portion; 24b), between above-mentioned bar portion and outer screw section, have encapsulant (23a, 23b); And a plurality of nozzle arrangements (20a, 20b) have in inside the electrode configuration space that is communicated with said nozzle (2a, 2b); Chip basal body (1); This chip basal body (1) has above-mentioned outer screw section to the bar portion that supplies each nozzle arrangement and inserts each logical nozzle arrangement patchhole (18a; 18b), lead in the above-mentioned umbrella portion and the preceding transverse plane (1d of each nozzle arrangement of each nozzle arrangement patchhole through inserting; 1e) butt and close and form said nozzle member patchhole a part and and above-mentioned bar portion between form the cold-producing medium free air space the cold-producing medium circulation port (1f, 1g), cold-producing medium bears refrigerant passing holes (1j) that the above-mentioned cold-producing medium circulation port that hole (1h), cold-producing medium portals (1i), will adjoin each other connects, one (1f) in the above-mentioned cold-producing medium circulation port born hole refrigerant passing holes (1k) that is connected and the refrigerant passing holes (1l) that another one (1g) in the above-mentioned cold-producing medium circulation port and above-mentioned cold-producing medium are portalled and be connected with above-mentioned cold-producing medium; And binding member (25a, 25b), this binding member (25a, 25b) will be inserted the said nozzle member that leads in said nozzle member patchhole and be fixed in the said chip matrix.
In addition, for easy understanding, in bracket the mark accompanying drawing shown in after state component symbol corresponding or suitable among the embodiment, with for reference as illustration.Following also identical.
According to the plasma gun that is equiped with this plug-in type chip (1), can carry out forming the welding of a plurality of electric arcs in single molten bath of a molten metal bath with a plurality of electric arcs.For example under the situation of the welding of two electric arcs in single molten bath that carry out forming a molten metal bath with two electric arcs; The cross section of plasma-arc becomes at welding travel direction (y) goes up elongated thermal source; Therefore; Bead fabric width (x direction) with respect to heat is suppressed narrowlyer, even change at a high speed, high temperature can not take place yet break.In addition, can be through becoming two electric arcs in single molten bath, and when thickness of slab is 3～10mm, carry out the aperture welding with front electric arc, carry out wide cut with back electric arc to touch the kiss welding, and make surperficial bead become smooth.During less than 3mm, can make surperficial bead become smooth with back electric arc at thickness of slab to dig welding under the electric arc of front.
Though leaving to a certain degree through use, the synchronous welding of two plasma guns of distance obtains roughly similar effects; But the electric arc on the welding travel direction broadens at interval, therefore; If the workpiece (welding object material) of short weld length; Then can not carry out welding, need two channel welds, thereby be not easy to change at a high speed at same passage.In addition, electric arc broadens at interval, and therefore, electric arc fusion once again once cakey bead in back needs high heat for back electric arc.According to using single-chip to comprise a plurality of arc weldings in single molten bath of the plug-in type chip of the present invention of a plurality of nozzle arrangements, nozzle shortens at interval, therefore, can address these problems.
In addition, the cold-producing medium circulation port of chip basal body (1) (1f, 1g) in, with each nozzle arrangement (20a, bar portion 20b) (22a, periphery surface 22b) flows contiguously has cold-producing medium (cooling water), therefore, (20a, cooling capacity 20b) is higher for each nozzle arrangement.In addition; In chip basal body (1); Mobile in the refrigerant passing holes (1l) that the refrigerant passing holes (1j) that cold-producing medium bears hole (1h) at cold-producing medium, a cold-producing medium circulation port (1f) and this cold-producing medium are born refrigerant passing holes (1k) that the hole is connected, the cold-producing medium circulation port that adjoins each other is connected, other cold-producing medium circulation port (1g) portalled with cold-producing medium (1i) are connected; Therefore, the cooling capacity of chip basal body (1) is also higher.
Thus, weld power is become welds greatly and more at high speed.When nozzle segment distortion that makes the nozzle arrangement lower end owing to Gao Re or melting loss, can replace this nozzle arrangement with new product, chip basal body still can be used on former state ground, thereby makes the maintenance cost become cheap.
