Abstract
The utility model relates to an abrasion resistant type submerged-arc welding contact tube, which belongs to the field of welding and particularly relates to a special contact tube for submerged-arc welding. The contact tube comprises a matrix of the contact tube and two alloy blocks; the alloy blocks are embedded at the two ends of the matrix of the contact tube; one alloy block is embedded at the entry end of the contact tube; the other alloy block is embedded at the exit end of the contact tube; through-holes are formed on the alloy blocks; the through-holes and the inner hole of the contact tube are in the same size; and the alloy blocks are welded in the contact tube through braze welding. The utility model has a simple structure, and can improve wear resisting property and reduce wear and tear while keeping good electric conductivity of the contact tube.
Description
Technical field
The wear-resisting formula submerged-arc welding of the utility model ignition tip belongs to welding field, particularly relates to the ignition tip that a kind of submerged arc welding is used.
Background technology
At present, known contact tip for welding adopts the red copper manufacturing, and material is softer.When welding wire passes through, because welding wire pushes the impression that the surface has wire feed rolls to cause through wire feed rolls, ignition tip is had scraping action, so the wearing and tearing of ignition tip endoporus are very fast, when may wear to a certain degree, when wire oscillation is big, then need to change ignition tip, need change the primary conductive mouth in general 8～24 hours.Make ignition tip if change a kind of harder material, the effect of conduction will be affected, and causes the welding current spread of voltage.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of anti-wear performance good, long service life, the ignition tip that the performance of conduction is good.
The purpose of this utility model reaches by following measure, it is by the ignition tip parent, alloy block is formed, alloy block is inlayed at parent two ends at ignition tip, alloy block is embedded in the arrival end of ignition tip, and alloy block is embedded in the port of export of ignition tip, and alloy block has through hole, clear size of opening and ignition tip endoporus consistent size, alloy block is welded in the ignition tip by brazing.Because the ignition tip two ends respectively are equipped with hard alloy blocks, the guiding force of welding wire is born by alloy block basically, characteristics such as hard alloy blocks has hard height, and anti-wear performance is good, so improved the wearability of ignition tip.And ignition tip is still made its parent by red copper, therefore still can keep electric conductivity good.
The utility model is installed a circular hard alloy blocks respectively at the ignition tip two ends, alloy block has through hole, and the outer end of alloy block through hole has interior chamfering, allows the easier ignition tip that passes of welding wire.
Of the present utility model simple in structure, when keeping the ignition tip electric conductivity good, can also improve anti-wear performance, reduce loss.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, accompanying drawing 2, the utility model is by ignition tip parent 2, inlet alloy block 1, outlet alloy block 3 is formed, and alloy block is embedded in the arrival end of ignition tip, and alloy block is embedded in the port of export of ignition tip, alloy block has through hole, clear size of opening and ignition tip endoporus consistent size, the outer end of alloy block through hole has interior chamfering, is welded in the ignition tip by brazing.
Claims (3)
1, a kind of wear-resisting formula submerged-arc welding ignition tip is characterized in that by the ignition tip parent, and alloy block is formed, and inlays alloy block at the parent two ends of ignition tip, and alloy block is embedded in the arrival end of ignition tip, and alloy block is embedded in the port of export of ignition tip, and alloy block has through hole.
2, wear-resisting formula submerged-arc welding ignition tip according to claim 1 is characterized in that the outer end of alloy block through hole has interior chamfering.
