Abstract
The utility model discloses a projection welding lower electrode comprising a lower electrode body and a lower electrode base, wherein the lower electrode body is arranged on the lower electrode base; and a water inlet tube joint and a water outlet tube joint are arranged at both sides of the lower electrode body. The utility model is characterized in that the lower electrode body comprises a cylinder lower electrode at the upper part and an electrode at the lower part; the lower electrode body is fixedly connected with the lower electrode base through an electrode connecting seat; and the electrode connecting seat and the cylinder lower electrode are in an integral structure. By arranging the lower electrode connecting seat at the lower part of a traditional cylinder lower electrode to enable the lower electrode and the lower electrode base to connect through the lower electrode connecting seat. Thus, the stability and the reliability of the total structure is improved, and meanwhile, the maintaining performance of frocks is also improved.
Description
Technical field
The utility model projection welding electrode can be widely used in metallic stamping pieces and the projection welding of many specifications nut, has improved the manufacturability of projection welding structure greatly, reliability, and improved the frock maintainability.
Background technology
Projection welding is mainly used in the stamping parts of welding low-carbon steel and low-alloy steel.In automobile and household electrical appliances hardware design at present, begin to adopt with metal parts or the direct projection welding of nut to another part, enhance productivity with this, reduce labour intensity.Mainly there are defectives such as poor rigidity, insufficient strength in present existing projection welding electrode structure shown in Fig. 1～2; Particularly when eccentric projection welding, because locating surface is little, under the effect of tilting force, strain can take place, make projection welding part discontinuity, can't reliably guarantee the formation weld nugget that salient point can be stable, be easy to generate rosin joint, influence the quality of projection welding.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of projection welding bottom electrode that can improve projection welding structural stability and reliability, to improve the qualification rate of product, improves the maintainability of frock simultaneously.
The technical scheme of the utility model technical solution problem is as follows:
A kind of projection welding bottom electrode, it comprises bottom electrode body and bottom electrode base, described bottom electrode body is fixedly installed on the bottom electrode base, bottom electrode body both sides are provided with the water-in and water-out pipe joint, it is characterized in that, described bottom electrode body comprises the cylindric bottom electrode on top and the electrode Connection Block of bottom, and described bottom electrode body is fixedlyed connected with the bottom electrode base by the electrode Connection Block, and described electrode Connection Block and cylindric bottom electrode are integral structure.
By above disclosed technical scheme as can be known, the utility model is provided with the bottom electrode Connection Block by the bottom at traditional round column type bottom electrode, make between bottom electrode and the bottom electrode base and link to each other by the bottom electrode Connection Block, improve the stability and the reliability of total, also improved the maintainability of frock simultaneously.The utility model is compared with existing traditional projection welding electrode technology, has the following advantages:
1. welding process is reliable and stable, welding quality height, constant product quality.
2. solved the manufacturability of projection welding structure.Improved production efficiency.
3. improved the service life of projection welding electrode.Reduce the frock manufacturing cost, improved the easy dimension of frock
Protecting property.
4. because of effectively having guaranteed welding quality, can suitably reduce the input of welding heat energy, save the energy.
