Description
Technical field
The present invention relates to welding equipment field of accessories, more particularly, to a kind of arc welding ignition tip.
Background technology
Ignition tip belongs to welding equipment consumable accessory, for the electric energy of welding machine is transferred to welding wire.
During welding, more than 1000 DEG C, current ignition tip adopts copper or copper alloy manufacture to arc temperature substantially, softens temperature
Degree is far below arc temperature, can be deformed, ignition tip endoporus can expand, due to current ignition tip in ignition tip softening process
Endoporus generally circular in cross section or oval, welding wire is generally circular in cross section, after endoporus expands, the endoporus of circular welding wire and ignition tip
Contact area reduces, and only one contact line sometimes leads to welding wire and ignition tip loose contact, not only affects welding effect, also
Ignition tip need to frequently be changed, efficiency is low, loss is big.
Content of the invention
It is an object of the invention to proposition is a kind of being difficult to come in contact bad arc welding ignition tip with welding wire.
For reaching this purpose, the present invention employs the following technical solutions:
A kind of arc welding ignition tip, including ignition tip body and limiting plate, described ignition tip body include thread segment and
Non-threaded section, described thread segment is connected with described non-threaded section, and described ignition tip body is provided with and runs through described thread segment and non-
The rhombus through hole of thread segment, described rhombus through hole is used for delivery welding wire, and the free end of described thread segment is provided with groove, described spacing
Plate and described groove fit, described limiting plate is provided with flower-shape through hole corresponding with described rhombus lead to the hole site, and described flower-shape leads to
Hole is used for ensureing described welding wire and at least two contact lines of described ignition tip.
Further, the profile of described flower-shape through hole is provided with multiple projections towards described flower-shape through hole center, adjacent protrusion
Between maximal clearance be less than described welding wire diameter.
Further, described projection is four, and described projection is arc, is connected to described in the cross-sectional profiles of described welding wire
Rhombus through hole, projection described with four is corresponding tangent respectively on four sides of described rhombus via profiles, and point of contact is interior with corresponding respectively
Contact overlaps.
Further, after described limiting plate embeds described groove, align with the end face of the free end of described thread segment.
Beneficial effects of the present invention have:
Arc welding proposed by the present invention ignition tip passes through to arrange rhombus through hole on ignition tip body, realizes ignition tip and exists
After softening transform, circular welding wire only has the probability of a contact line to reduce with ignition tip endoporus, and is led to by being provided with flower-shape
The limiting plate in hole, makes welding wire cannot keep stable in wall scroll contact line, further ensures welding wire with described ignition tip at least
There are two contact lines.

Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
As depicted in figs. 1 and 2, a kind of arc welding ignition tip, including ignition tip body 1 and limiting plate 2, ignition tip body
Including thread segment 11 and non-threaded section 12, thread segment 11 is connected with non-threaded section 12, and ignition tip body 1 is provided with and runs through thread segment
11 and non-threaded section 12 of rhombus through hole 13, rhombus through hole 13 is used for delivery welding wire 3, and the free end of thread segment 11 is provided with groove
14, limiting plate 2 is coordinated with groove 14, and limiting plate 2 is provided with flower-shape through hole 15 corresponding with rhombus through hole 13 position, flower-shape through hole
15 are used for ensureing welding wire 3 and at least two contact lines of ignition tip.
The present embodiment passes through to arrange rhombus through hole 13 on ignition tip body 1, realizes ignition tip after softening transform, circular
Welding wire 3 only have the probability of a contact line to reduce with ignition tip endoporus, and by being provided with the limiting plate 2 of flower-shape through hole 15,
Make welding wire 3 cannot keep stable in wall scroll contact line, further ensure welding wire 3 and contact at least two with described ignition tip
Line.
If flower-shape through hole 15, because the length of ignition tip body 1 is longer, difficult processing are directly arranged on ignition tip body 1
Spend big, high cost, setting limiting plate 2 greatly reduces cost, and it is bad to prevent ignition tip and welding wire 3 from coming in contact
Effect is fine.
As shown in figure 3, the profile of flower-shape through hole 15 is provided with multiple projections 151 towards flower-shape through hole center, adjacent protrusion
Maximal clearance between 151 is less than the diameter of welding wire 3, thus it is ensured that welding wire 3 at least can contact after the endoporus of ignition tip expands
Two adjacent projections 151.
In the present embodiment, raised 151 are four, and to correspond to the profile of rhombus through hole 13, raised 151 are arc, more make
Obtain circular welding wire 3 and can not stably contact single line, in the cross-sectional profiles of welding wire 3, be connected to rhombus through hole 13, rhombus through hole
Four sides of 13 profiles are corresponding tangent with four projections 151 respectively, and point of contact is overlapped with corresponding inner contact respectively, facilitates welding wire 3
Seal wire.
In the present embodiment, after limiting plate 2 embeds groove 14, align with the end face of the free end of thread segment 11, facilitate and lead
The component of sparking plug connects.
Obviously, the above embodiment of the present invention merely to clearly illustrate example of the present invention, and be not to this
The restriction of the embodiment of invention.For those of ordinary skill in the field, acceptable on the basis of the above description
Make the change of other multi-forms.There is no need to be exhaustive to all of embodiment.All essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included in the protection model of the claims in the present invention
Within enclosing.
