Under the synergy of power and underthrust power, broken and tamping operation carried out to hardened railway roadbed, thus tamping pickaxe bear make power meeting firm by ramming
Several times increase, in the design process, although helve has used steel alloy overall structure, for examining for complete machine production cost
Consider, the service life of material is often less than the overall service life of complete machine other component, causes occur tamping pickaxe head earlier
Portion's abrasion deformation need to be replaced in advance when more than service limits, and tamping car and tamping unit belong to railway special equipment, design space
Compact, complicated, repair and replacement tamping pickaxe operating difficulties, working strength is larger, is replaced as frequently as tamping pickaxe and increases equipment use
The labor intensity of personnel, meanwhile, tamping pickaxe belongs to basic vulnerable part, and demand is larger, influences complete machine use cost, currently, tamping pickaxe
Manufacture be tamping pickaxe head position patch weldering antifriction alloy weld tabs, increase tamping pickaxe head wear-resisting property, such processing technology
There are two problems, and antifriction alloy weld tabs cost is higher, using soldering tech, the tamping pickaxe head part relative complex to shape, it is difficult to
Accomplish that each position alloy sheet can be realized and the fusion of matrix, processing technology difficulty are larger.
Invention content
Present invention seek to address that the above problem, can reduce cost to provide one kind, increase tamping pickaxe head position wearability
The tamping pickaxe head bead-welding technology that can, prolong the service life.
The present invention solves described problem, the technical solution adopted is that：
A kind of tamping pickaxe head bead-welding technology, includes the following steps：
S1：Matrix is processed, and at middle carbon or the tamping pickaxe head matrix position of medium carbon alloy steel material, upper and lower two surface areas process ruler
Very little and distribution rectangle weld groove appropriate；
S2：In tamping pickaxe head baseline top processing dimension trapezoidal weld groove appropriate；
S3：Backing welding, selection are suitable for middle carbon or the welding rod of medium carbon alloy steel tamping pickaxe head basic material welding performance, are welded in rectangle
The bottoming overlay cladding of built-up welding suitable thickness in slot and trapezoidal weld groove；
S4：Wearing layer built-up welding selects wear-resisting property to meet tamping pickaxe head applying working condition, has high wear resistance, and and prime coat
The good wear resistance electrode of welding performance is fused, the built-up welding of wearing layer is carried out on the basis of bottoming layer；
S5：Surface layer seine weldering, and wearing layer welding bead is in pairs, with wear resistance electrode, is pressed on the basis of wearing layer welding bead to a fixed inclination
Mutual certain intervals distance arrangement, carries out the built-up welding for drawing net shape skin.
Using the present invention of above-mentioned technical proposal, compared with prior art, the feature protruded is：
Under the premise of reducing cost, according to tamping pickaxe force-bearing situation, the main part of transmitting forces and straight with ballast is distinguished
The tamping pickaxe head position of contact carries out wearing layer bead-welding technology, to increase tamping pickaxe head position to the tamping pickaxe head position of serious wear
Wear-resisting property, extend tamping pickaxe head service life, improve the ratio of performance to price of tamping pickaxe.

Specific implementation mode：
With reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands the content of present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of tamping pickaxe head bead-welding technology includes the following steps：
S1：Matrix is processed, and at middle carbon or the tamping pickaxe head matrix position of medium carbon alloy steel material, upper and lower two surface areas process ruler
Very little and distribution rectangle weld groove 1 appropriate.
S2：In tamping pickaxe head baseline top processing dimension trapezoidal weld groove 2 appropriate.
S3：Backing welding, selection is suitable for middle carbon or the welding rod of medium carbon alloy steel tamping pickaxe head basic material welding performance, in square
