Abstract

The utility model provides an external circulating water-cooled lower electrode suitable for bolt and nut projection welding, comprising an electrode holder, an electrode tip and insulating sleeves, wherein the electrode tip is arranged on the electrode holder, and the insulating sleeves are arranged in the central hole of the electrode tip and the electrode holder; a cooling water channel is arranged at the lower part of the electrode holder, and a circle of cooling water jacket is arranged at the upper part of the electrode holder close to the periphery of the electrode tip; and a water inlet joint and a backwater joint are respectively arranged on the cooling water jacket. The lower electrode adopts an integral external circulating water-cooled structure, so that the cooling water cools through the bottom of the electrode holder and through entering the cooling water jacket at the upper part, with good cooling effect, and the electrode can quickly conduct heat to avoid burning the electrode, prolong the service life of the electrode and reduce the consumption of the insulating sleeves, thereby ensuring the stability of welding quality and reducing the production cost.

Description

A kind of outer circulation water-cooled bottom electrode that is applicable to bolt, nut projection welding
Technical field
The utility model belongs to the welding electrode structure.
Background technology
Welding for bolt, nut, traditional lower electrode arrangement as shown in Figure 1, its cooling water can only lead to electrode tip holder 1 bottom, electrode tip end face 21 is far away from cooling water, its heat can't conduct to cooling water fast, and a large amount of heat that welding produces can make electrode tip 2 annealing or by scaling loss, lose elevated temperature strength, reduce conductance, thus the life-span of reducing electrode greatly.Endoporus first and second insulating bushings 31 and 32 also are easy to be caused frequent replacing by scaling loss simultaneously, waste man-hour and raising production cost.Therefore, for the welding of this series products, it is particularly important that the cooling performance of bottom electrode just seems.
Summary of the invention
The purpose of this utility model is to propose a kind of outer circulation water-cooled bottom electrode that is applicable to bolt, nut projection welding at the deficiency of prior art existence, prolongs the service life of electrode, reduces the consumption of insulating bushing.
The technical solution of the utility model is as follows:
A kind of outer circulation water-cooled bottom electrode that is applicable to bolt, nut projection welding, comprise electrode tip holder, be installed in the electrode tip on the electrode tip holder and be installed in electrode tip and the centre bore of electrode tip holder in insulation sleeve; Has the cooling water aquaporin in described electrode tip holder bottom; Described electrode tip holder top is provided with a circle cooling jacket near the periphery of electrode tip, and is respectively arranged with water supply connector and backwater joint on cooling jacket.
This bottom electrode has adopted the outer circulation water-cooling structure, cooling water is except cooling off by the electrode tip holder bottom, the cooling jacket that also enters top cools off, cooling effect is better, can make electrode reach the effect of rapid conduction heat, avoids the scaling loss of electrode, prolong the service life of electrode, reduce the consumption of insulating bushing, thereby guarantee the stability of welding quality, reduce production costs.

Fig. 3 is the structural representation that the utility model proposes the bottom electrode that is applicable to the nut projection welding
The specific embodiment
Referring to Fig. 2, for the bottom electrode that is applicable to the bolt projection welding, this outer circulation water-cooled bottom electrode by electrode tip holder 1, be installed in the electrode tip 2 on the electrode tip holder and be installed in electrode tip and the centre bore of electrode tip holder in first insulation sleeve 31 and second insulation sleeve 32, be arranged on electrode tip holder top and form near the circle cooling jacket 4 that the periphery of electrode tip is provided with, be respectively arranged with water supply connector 5 and backwater joint 6 on the cooling jacket 4, the electrode tip holder bottom keeps original cooling-water duct 7.Like this, water supply connector 5 is connected with the circulating water pipe of backwater joint 6 with the outside,, can effectively cools off electrode by the turnover and the flow size of external control cooling water.
Referring to Fig. 3, for the bottom electrode that is applicable to the nut projection welding, except it also is equipped with location core 8 in insulation sleeve (this is the original structure of electrode), the structure of its cooling water outer circulation is applicable to that with the front bottom electrode of bolt projection welding is identical.
