Abstract
The utility model discloses a contact tube, comprising a contact tube, wherein a connector is arranged on one end of the contact tube; a nozzle is arranged on the other end of the contact tube; the nozzle is in a conical structure; a metal ceramic shell made of a mixed material of nickel-based alloy and metal ceramic powder is covered on the outer wall of the nozzle.
Description
Technical field
The utility model relates to the automatic welding device technical field, specifically is a kind of ignition tip.
Background technology
Along with oil, petrochemical industry, waterline construction, high ferro steel pipe arch form bridge construction, the high speed development of industries such as pressure vessel manufacturing, the metal solder dependence increases year by year; Welding critical piece ignition tip, traditional processing technology only carries out copper material machine-shaping, and the surface is the unprotect layer all; Make the ignition tip surface charging, be prone to contact sparking with workpiece and burn ignition tip, the surface is not wear-resisting fragile; Increased and changed the number of times of ignition tip, thereby prolonged the engineering time, caused inconvenience to construction.
Summary of the invention
The purpose of the utility model provides a kind of ignition tip, has overcome the above-mentioned deficiency of prior art, and is simple in structure, easy to use, can make the ignition tip surface insulation, helps improving the service life of ignition tip.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model adopts is following:
A kind of ignition tip comprises ignition tip, and said ignition tip one end is provided with connector, and the ignition tip other end is provided with shower nozzle, and said shower nozzle is a conical structure, the ceramic and metal package of shower nozzle outer wall parcel nickel-base alloy and metal ceramic powder made from mixed materials.
The terminal sidewall of said shower nozzle is provided with ceramic and metal package outward.
Preferably, said ceramic and metal package is socketed in the shower nozzle outer wall, and bonding firm.
More preferably, said ceramic and metal package is for directly being sprayed on the formation of shower nozzle outer wall with nickel-base alloy and metal ceramic powder mixed solution.
Further, the thickness of said ceramic and metal package is 0.02 ~ 0.03mm.
The beneficial effect of the described ignition tip of the utility model is: simple in structure; Easy to use; Ceramic and metal package can make the ignition tip surface insulation; Even ignition tip contacts also with workpiece and can not strike sparks, ceramic and metal package can also provide the case hardness greater than 200HB, prolongs the service life of ignition tip greatly.
Ceramic and metal package also has thin thickness, high temperature resistance, wear-resistant, anticorrosive, high reliability features; Be beneficial to welding procedure and use and reduce the number of times of replacing ignition tip, increase its service life.
Description of drawings
Fig. 1 is the sketch map of the described ignition tip of the utility model embodiment.
Fig. 2 is the cutaway view of the described ignition tip of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the optimum implementation of the utility model is done further detailed description.
Shown in Fig. 1-2, the described ignition tip of the utility model embodiment comprises ignition tip 100; Said ignition tip 100 1 ends are provided with connector 2, and ignition tip 100 other ends are provided with shower nozzle 1, and said shower nozzle 1 is a conical structure; Shower nozzle 1 outer wall coated metal ceramic package 3 can make ignition tip 100 surface insulations through ceramic and metal package 3, can not strike sparks even ignition tip 100 contacts also with workpiece; Ceramic and metal package 3 can also provide the case hardness greater than 200HB, prolongs the service life of ignition tip greatly.
In the practical implementation, said shower nozzle 1 terminal sidewall is provided with ceramic and metal package 3 outward.
The thickness of said ceramic and metal package 3 is 0.02 ~ 0.03mm.
Said ceramic and metal package 3 is socketed in shower nozzle 1 outer wall, and bonding firm.
Said ceramic and metal package 3 preferred production methods form for being painted on shower nozzle 1 outer wall.
The said manufacturing process that is painted on shower nozzle 1 outer wall formation ceramic and metal package 3 is:
(1) select for use nickel-base alloy and metal ceramic powder etc. fully to mix;
(2) with high-speed flame (HVOF) mixed-powder is heated (heating-up temperature is generally about 3000 ℃);
(3) ignition tip 100 is placed on the rotating shaft; Make its spinning; Utilize flame flow with the powder under the molten state with do not melt powder and spray to shower nozzle 1 surface of ignition tip 100, form the ceramic and metal package 3 of few hole, suboxides, high adhesion, low residual force with ultrahigh speed.
The preferred embodiment of this specific embodiment the utility model can not limit the utility model, and concrete each item rights protection scope is defined by the claims.
