Description
Technical field
The utility model belongs to conductive electrode technical field, relates to for big current resistance welding electrode, is specifically related to durable type resistance spot weld electrode cap.
Background technology
Electric resistance welding is after two workpiece combinations to be welded, applies certain pressure and voltage by paired electrode, utilizes resistance heat fusing workpiece local mother metal between workpiece, makes it to form rigidly connected welding technique.Its resistance spot welding process feature is low-voltage, big current short time.Like this while the resistance heat generated to make between workpiece to be welded local instantaneous high-temperature fusing form welding point, be also afford high temperature with the conductive electrode of absorption surface, along with frequent welding electrode head softens, is easy to conquassation deglabration, need frequent reconditioning electrode tip.When electrode tip reconditioning is exactly that electrode is scrapped to a certain extent.
Along with industrial automation development, the generation of welding robot, resistance spot welding adopts integral electrodes to be far from suitable, detachable electrode-----electrode stem+electrode cap body is born and achieves a milestone revolution, using till today along with attrition only changes electrode cap, is that material consumption is greatly reduced.Subsequently for extending service life of electrode cap, people's research direction mainly concentrates on the new material of electrode cap, and this namely progressively develops into from initial red copper, chromium zirconium copper so that alumina dispersion-strenghtened copper.But, although existing electrode is provided with the cooling duct be interconnected in electrode cap and electrode cap body, but, being positioned at the intrinsic cooling duct of electrode cap is a cylindrical blind hole, the thermal diffusivity of cooling cavities to electrode cap body of this structure is poor, causes the service life of electrode cap short.
Summary of the invention
The purpose of this utility model is being the mash welder electrode cap providing a kind of long service life.
The technical scheme solved the problems of the technologies described above is as follows:
Mash welder electrode cap, comprises electrode cap body, and one end of this electrode cap body is provided with the first Cooling Holes, and the first Cooling Holes is axial arranged along electrode cap body; And
Electrode stem, one end of this electrode stem is connected with the end with the first Cooling Holes of electrode cap body, and electrode stem is provided with axial through hole;
Electrode cap body is also provided with the second Cooling Holes, and this second Cooling Holes arranges along the axis of electrode cap body and is communicated with the first described Cooling Holes, and the second Cooling Holes is blind hole.
The area of section of the second Cooling Holes is less than the area of section of the first Cooling Holes, between the second Cooling Holes and the first Cooling Holes, be formed with step.
The degree of depth of described second Cooling Holes is 3 to 5mm.
The cross section of the wall surface of the hole of described second Cooling Holes is arch.
Also comprise cooling tube, one end of this cooling tube extend in the first Cooling Holes or the second Cooling Holes through after the through hole on electrode stem.
The material of electrode cap body is chromium pick copper, tungsten copper, alumina dispersion-strenghtened copper.
The utility model is by after installing electrode cap and adding the second Cooling Holes bottom internal taper hole, the larger flowing space is defined to cooling fluid, and reach following technique effect: because the first Cooling Holes and the second Cooling Holes are the shape of stepped hole, obtain enhancing than the structural strength of conventional cylindrical hole, make it to bear larger welding pressure and welding current.First Cooling Holes and the second Cooling Holes increase film-cooled heat, the resistance heat radiating effect produced between welding process electrode cap body and workpiece is significantly improved, electrode cap body has red hardness and is maintained very well, electrode cap reconditioning batch is reduced, thus improve electrode cap service life, reduce welding production cost.
Electrode cap of the present utility model is in similar material used, constant in use amount, processing charges is constant, electrode cap body and electrode stem install connected mode compared with existing electrode cap under constant prerequisite, changed by electrode cap body interior structural design, extend electrode cap service life, reduce the electrode cap reconditioning frequency, save replacing electrode cap holding time, enhance productivity, final realization reaches and reduces production cost effect.
Below in conjunction with the drawings and specific embodiments, structure of the present utility model and principle are described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Detailed description of the invention
As shown in Figure 1, mash welder electrode cap of the present utility model, comprises electrode cap body 1, electrode stem 3 and cooling tube 4, is described in detail below to each part and the relation between them:
The material of electrode cap body 1 is chromium pick copper, tungsten copper, alumina dispersion-strenghtened copper, and the Advantageous materials of electrode cap body 1 adopts alumina dispersion-strenghtened copper.One end of this electrode cap body 1 is provided with the first Cooling Holes 1a, and axial arranged along electrode cap body of the first Cooling Holes 1a, the first Cooling Holes 1a is taper hole.The surface of the other end of electrode cap body 1 is sphere.Electrode cap body 1 is also provided with the second Cooling Holes 2, this second Cooling Holes 2 arranges along the axis of electrode cap body 1 and is communicated with the first described Cooling Holes 1a, and the second Cooling Holes 2 is blind hole.The area of section of the second Cooling Holes 2 is less than the area of section of the first Cooling Holes 1a, between the second Cooling Holes 2 and the first Cooling Holes 1a, be formed with step.The degree of depth of described second Cooling Holes 2 is 3 to 5mm.The cross section of the wall surface of the hole of described second Cooling Holes 2 is arch.
One end of electrode stem 3 is connected with the end with the first Cooling Holes 1a of electrode cap body 1, the end be connected with electrode cap body 1 of electrode stem 3 is tapered, like this, the tapered end of electrode stem 3 is inserted in the first Cooling Holes 1a of electrode cap body 1 to be formed and closely cooperates, and the axial end of the tapered end of electrode stem 3 and the step between the second Cooling Holes 2 and the first Cooling Holes 1a leave interval.Electrode stem 3 is provided with axial through hole, and this through hole is used for the assembling of cooling tube 4.
One end of cooling tube 4 is through extending in the first Cooling Holes 1a or the second Cooling Holes 2 after the through hole on electrode stem 3, and preferably, the end of cooling tube 4 extend in the first Cooling Holes 1a.
