Description
Technical field
The utility model relates to welding equipment field of accessories, particularly relates to a kind of arc welding ignition tip.
Background technology
Ignition tip belongs to welding equipment consumable accessory, for by the delivery of electrical energy of welding machine to welding wire.
During welding, arc temperature is more than 1000 DEG C, current ignition tip adopts copper or copper alloy manufacture substantially, softening temperature is far below arc temperature, distortion can be produced in ignition tip softening process, ignition tip endoporus can expand, endoporus due to current ignition tip is generally circle or ellipse, and welding wire is generally circle, after endoporus expands, circular welding wire and the endoporus contact area of ignition tip reduce, sometimes only have a contact wire, cause welding wire and ignition tip loose contact, not only affect welding effect, also need frequently to change ignition tip, efficiency is low, loss is large.
Utility model content
The purpose of this utility model is that proposition is a kind of and not easily comes in contact bad arc welding ignition tip with welding wire.
For reaching this object, the utility model by the following technical solutions:
A kind of arc welding ignition tip, comprise ignition tip body and limiting plate, described ignition tip body comprises thread segment and non-threaded section, described thread segment and described non-threaded section are connected, described ignition tip body is provided with the rhombus through hole running through described thread segment and non-threaded section, described rhombus through hole is used for delivery welding wire, the free end of described thread segment is provided with groove, described limiting plate and described groove fit, described limiting plate is provided with the colored shape through hole corresponding with described rhombus lead to the hole site, described colored shape through hole is for ensureing that described welding wire and described ignition tip have two contacts wire at least.
Further, the profile of described colored shape through hole is provided with multiple projection towards described colored shape through hole center, and the maximal clearance between adjacent protrusion is less than the diameter of described welding wire.
Further, described projection is four, and described projection is arc, is connected to described rhombus through hole in the cross-sectional profiles of described welding wire, and projection described with four is corresponding tangent respectively on four limits of described rhombus via profiles, and point of contact overlaps with corresponding inner contact respectively.
Further, after described limiting plate embeds described groove, align with the end face of the free end of described thread segment.
The beneficial effects of the utility model have:
The arc welding ignition tip that the utility model proposes by arranging rhombus through hole on ignition tip body, realize ignition tip after softening transform, circular welding wire and ignition tip endoporus only have the probability of a contact wire to reduce, and by being provided with the limiting plate of colored shape through hole, make welding wire cannot keep stable on wall scroll contact wire, further ensure welding wire and described ignition tip has two contacts wire at least.
Accompanying drawing explanation
Fig. 1 is the detonation configuration schematic diagram of a kind of arc welding ignition tip that the utility model embodiment provides;
Fig. 2 is the rearview that arc welding ignition tip that the utility model embodiment provides coordinates with welding wire;
Fig. 3 is the structural representation of the limiting plate that the utility model embodiment provides.
In figure, 1, ignition tip body; 11, thread segment; 12, non-threaded section; 13, rhombus through hole; 14, groove; 15, shape through hole is spent; 151, protruding; 2, limiting plate; 3, welding wire.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of arc welding ignition tip, comprise ignition tip body 1 and limiting plate 2, ignition tip body comprises thread segment 11 and non-threaded section 12, thread segment 11 is connected with non-threaded section 12, ignition tip body 1 is provided with the rhombus through hole 13 running through thread segment 11 and non-threaded section 12, rhombus through hole 13 is for delivery welding wire 3, the free end of thread segment 11 is provided with groove 14, limiting plate 2 coordinates with groove 14, limiting plate 2 is provided with the colored shape through hole 15 corresponding with rhombus through hole 13 position, and flower shape through hole 15 is for ensureing that welding wire 3 and ignition tip have two contacts wire at least.
The present embodiment by arranging rhombus through hole 13 on ignition tip body 1, realize ignition tip after softening transform, circular welding wire 3 only has the probability of a contact wire to reduce with ignition tip endoporus, and by being provided with the limiting plate 2 of colored shape through hole 15, make welding wire 3 cannot keep stable on wall scroll contact wire, further ensure welding wire 3 and have two contacts wire at least with described ignition tip.
If directly arrange colored shape through hole 15 on ignition tip body 1, because the length of ignition tip body 1 is longer, difficulty of processing is excessive, high cost, arranges limiting plate 2 and greatly reduces cost, and it is fine to prevent ignition tip and welding wire 3 from coming in contact bad effect.
As shown in Figure 3, the profile of flower shape through hole 15 is provided with multiple projection 151 towards flower shape through hole center, maximal clearance between adjacent protrusion 151 is less than the diameter of welding wire 3, thus after the endoporus of ignition tip expands, guarantee welding wire 3 at least can contact two adjacent projections 151.
In the present embodiment, protruding 151 is four, with the profile of corresponding rhombus through hole 13, protruding 151 are arc, more make circular welding wire 3 stably can not contact single line, be connected to rhombus through hole 13 in the cross-sectional profiles of welding wire 3, four limits of rhombus through hole 13 profile are corresponding tangent with four projections 151 respectively, point of contact overlaps with corresponding inner contact respectively, facilitates the seal wire of welding wire 3.
In the present embodiment, after limiting plate 2 embeds groove 14, align with the end face of the free end of thread segment 11, be conveniently connected with the component of ignition tip.
Obviously, above-described embodiment of the present utility model is only to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, other multi-form change can also be made on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
