Abstract
The utility model relates to a kind of electrode tip of abundant contact weld surface, belongs to resistance welding techniques field.Described electrode tip comprises head and grips portion, the cylinder of convex curvature centered by described head, described convex curvature is solder side, the radius of curvature of described convex curvature is less than the radius of the bottom surface of cylinder, its curvature is 0.01 ~ 0.05, and the portion of gripping is the cylinder identical with head bottom surface radius, described in grip in portion and be provided with cavity, the diameter of cavity is corresponding with adaptive electrode arm head, and the length of cavity is 1 ~ 1.2 times of head.The utility model can increase the contact area of electrode tip and workpiece, solves ordinary electrode head bonding area little, the problem that not prison welding is solid, and wearability is strong, electrode tip long service life.
Description
Technical field
The utility model relates to resistance welding techniques field, specifically, is a kind of electrode tip of abundant contact weld surface.
Background technology
The geometry of auto parts and components is varied, its welding position on-plane surface, and welding position is positioned to the welding of the narrow side of inside workpiece, common electrode tip cannot touch solder side, cannot complete welding processing.And common electrode tip in use wear intensity is large, service life is short, needs often to change.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of electrode tip of abundant contact weld surface.
For achieving the above object, the utility model provides following technical scheme:
The utility model relates to a kind of electrode tip of abundant contact weld surface, described electrode tip comprises head and grips portion, it is characterized in that: the cylinder of convex curvature centered by described head, described convex curvature is solder side, the radius of curvature of described convex curvature is less than the radius of the bottom surface of cylinder, its curvature is 0.01 ~ 0.05, the portion of gripping is the cylinder identical with head bottom surface radius, described gripping in portion is provided with cavity, the diameter of cavity is corresponding with adaptive electrode arm head, and the length of cavity is 1 ~ 1.2 times of head.
As further scheme of the present utility model, described electrode tip is that chrome zirconium copper alloy punching press is one-body molded.
Compared with prior art, good effect of the present utility model is:
1. the utility model can increase the contact area of electrode tip and workpiece, solves ordinary electrode head bonding area little, the problem that not prison welding is solid.
2. electrode tip of the present utility model is that chrome zirconium copper alloy punching press is one-body molded, and head density is large, and mar proof is strong, and without the need to often changing electrode tip, reduce the wastage cost.
Accompanying drawing explanation
Fig. 1 is a kind of front view of electrode tip of abundant contact weld surface;
Mark in accompanying drawing 1 is respectively: 1. head; 2. grip portion; 3. solder side; 4. cavity.
Detailed description of the invention
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of electrode tip of abundant contact weld surface, described electrode tip comprises head 1 and grips portion 2, it is characterized in that: the cylinder of convex curvature centered by described head 1, described convex curvature is solder side 3, the radius of curvature of described convex curvature is less than the radius of the bottom surface of cylinder, and its curvature is 0.01 ~ 0.05.Gripping portion 2 is the cylinder identical with head bottom surface radius, described in grip in portion 2 and be provided with cavity 4, the diameter of cavity 4 is corresponding with adaptive electrode arm head, and the length of cavity 4 is 1 ~ 1.2 times of head 1.
Because the conductance of electrode tip is higher, generate heat less, this electrode tip is that chrome zirconium copper alloy punching press is one-body molded, and head density is large, and conductance is low, and generate heat high, temperature at weld is high, can reach welding requirements.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the utility model, any Reference numeral in claim should be considered as the claim involved by limiting.
