Abstract
The utility model discloses a welding head structure of a spot welding machine. The welding head structure of the spot welding machine comprises an upper die (1) and a lower die (2) which is a cylinder, the end face of the lower die (2) is a plane, the diameter of the lower die (2) is larger than that of the upper die (1), the diameter of the lower die (2) is increased, and the upper surface of the lower die (2) is smooth, contact area of a workpiece and the lower die (2) is enlarged, and a welded product is smooth and uniform in outer surface and free of pits.
Description
Technical field
The utility model belongs to the mash welder apparatus field, relates in particular to a kind of point welding machine welding head structure.
Background technology
It all is the structure of plush copper that the soldering tip of present all mash welders all adopts upper and lower, upper and lower mould is the identical prong structure of shape, in the welding process, form distortion and the surface crater of workpiece easily, make the shaping workpiece surface irregularity, surface of the work is uneven after the application, has a strong impact on product quality.
The utility model content
Form the distortion of workpiece and the defective of surface crater easily at the soldering tip of conventional point welding machine in the welding process, technical problem to be solved in the utility model provides a kind of smooth unanimity of product external surfaces that makes after the welding, the point welding machine welding head structure of no pit.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of point welding machine welding head structure, comprise upper die and lower die, and described counterdie is cylinder, and the counterdie end face is the plane, and described mode diameter down is greater than the described mode diameter of going up.
Be provided with cooling system in the described counterdie.
Advantage of the present utility model is that counterdie is cylindrical, enlarged diameter, and upper surface is smooth; increase the contact area of workpiece and counterdie, make the smooth unanimity of product external surfaces after the welding, no pit; be provided with cooling system in the counterdie, can reduce the heat in the welding process, workpiece is played a protective role.
Description of drawings
Fig. 1 is the structural representation of a kind of point welding machine welding head structure of the utility model;
Fig. 2 is the prior art structural representation;
Mark among the above-mentioned figure is: 1, patrix, 2, counterdie.
The specific embodiment
Fig. 1 is the structural representation of a kind of point welding machine welding head structure of the utility model, comprises patrix 1 and counterdie 2, and counterdie 2 is cylinder, and counterdie 2 end faces are the plane, and counterdie 2 diameters are greater than patrix 1 diameter.Be provided with cooling system in the counterdie 2.Counterdie 2 enlarged diameter arrive
25mm, and upper surface is smooth, increases the contact area of workpiece and counterdie 2.
Advantage of the present utility model is; counterdie 2 is cylindrical; enlarged diameter; and upper surface is smooth, strengthens the contact-making surface of workpiece and counterdie 2, makes the smooth unanimity of product external surfaces after the welding; no pit; be provided with cooling system in the counterdie 2, can reduce the heat in the welding process, workpiece is played a protective role.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
Claims (2)
