Abstract
The invention relates the manufacturing technique and structure of resistance spot welding retractable spring barrier housing electrode. It possesses the good fire resistant property, intensity, tenacity, shockproof and resilient deformation ability. It can improve the welding quality and reduces the injury of welding slag splashing.
Description
Described technical field
The present invention relates to outer splash of a kind of resistance spot welding and welding slag screen protective device electrode, during the especially a kind of outer splash that can in the resistance spot welding welding process, take place, stop and shield a kind of security protection welder of the welding slag that splashes, telescopic spring sheath electrode for resistance spot welding is the telescopic spring sheath electrode.
Background technology
At present, known in the resistance spot welding welding process of craft, because electrode end surface and face of weld loose contact or supply voltage pulsation are unstable, splash outside the face of weld takes place in welding process, the hot welding slag of high temperature splashes to diffusion all around at a high speed, is very easy to human body skin and eye are damaged.
Summary of the invention
In order to overcome at present in resistance spot welding process, because of the outer splash of face of weld takes place, may damage and deficiency human body, the invention provides the outer splash welding slag shielding protection electrode assembly of a kind of resistance spot welding is the telescopic spring sheath electrode, not only externally the welding slag of splash has the favorable protection shielding action, and can form closed fuel factor space at face of weld, reduce the oxidation bad reaction of face of weld.
The present invention solves the technical scheme that its technical problem takes and promptly it is characterized in that: telescopic spring sheath electrode for resistance spot welding is made up of resistance spot welding welding electrode and telescopic sheath.
In the resistance spot welding welding process, when the electrode tip working face press to face of weld the time, the telescopic sheath bottom end face is also along with electrode is pressed to face of weld, and contact prior to electrode tip and welding work pieces surface, the bottom end face that makes welding work pieces face of weld and telescopic sheath closely subsides with.Telescopic sheath is subjected to the pressure generation strain of face of weld simultaneously, and forms closed space around electrode tip and face of weld.When electrode end surface compressed face of weld and switches on, the face of weld of welding work pieces was under the effect of electrical heat energy and electrode pressure, and during splash, welding slag is along the radial high velocity jet in welding center outside welding work pieces surface is melted and taken place.Because telescopic sheath is with welding electrode end and workpiece face of weld and outside isolated and sealing, the welding slag that hot high speed is splashed is in the process of spraying, stopped by the inner wall surface of telescopic sheath and shield, can not go out the shielding of telescopic sheath.Reduced the injury that the welding slag of high temperature and high speed may cause to human body.
Because the welding slag of high velocity jet is stopped by telescopic sheath, its kinetic energy partly is converted into heat energy, make the inner environment that produces good face of weld fuel factor of telescopic sheath, telescopic sheath inside is in welding process, keep the fuel factor environment of a HTHP, outside low-pressure gas can not enter telescopic sheath inside, and welding surface oxidation and corrosivity are reduced.
Telescopic sheath is in welding process, and strain has taken place in the effect that is subjected to the pressure of electrode and weldment face of weld, and the shortening of its Y length makes between the spring matrix of telescopic sheath to fit tightly, and goes into airtight space.When welding process finishes, the weldment face of weld is left on the electrode tip surface, the effect that telescopic sheath loses external force returns to the preceding shape of strain again, simultaneously in welding process, accumulate in the welding slag of telescopic sheath inwall, in the process that the telescopic sheath strain is recovered, peel off and separate from the telescopic sheath inner wall surface.
The telescopic sheath top is fixed on the electrode, and the thrust groove is installed or thrust ring to prevent telescopic sheath loosening and landing takes place, and also can design the structure that changes fast, so that the reconditioning of electrode.
In welding process, the bottom end face of telescopic sheath is smooth, and flatness is good, and contacts with the weldment face of weld and fit, and has reached airtight.Telescopic spring sheath electrode and telescopic sheath have good high-temperature stability, and intensity and toughness are higher, anti-sticking damage and impact, and telescopic sheath has the excellent elasticity deformability.
The structure and the manufacturing process of telescopic spring sheath electrode are simple, and telescopic sheath can manufacture cylinder type etc., and the spring matrix cross sections can be taked shapes such as circle, rectangle.
Telescopic sheath for resistance spot welding is by the top, and spring matrix and bottom end face are formed.
The material of telescopic spring sheath electrode for resistance spot welding is selected according to the material of weldment, can take to have the good electric conductivity and the material of heat-conduction-type, and high temperature resistant and impact, as Cu alloy material.Telescopic sheath has good intensity and toughness and elastic deformability, and as Cu alloy material, the electric conductivity of telescopic sheath should be lower than welding electrode.
The invention has the beneficial effects as follows, the structure and the manufacturing process of telescopic spring sheath electrode for resistance spot welding are simple, have good high-temperature stability, and intensity and toughness are higher, anti-sticking damage and impact, telescopic sheath has the excellent elasticity deformability.Telescopic spring sheath electrode can corresponding raising weldment surface welding quality, reduce welding slag and splash the injury of human body.
