Abstract
The utility model relates to the technical field of welding, in particulate to an air cooling splashing proof projection welding top electrode. The air cooling splashing proof projection welding top electrode comprises a top electrode body and is characterized in that a circulating water channel and a splashing guide groove are arranged inside the top electrode body, the splashing guide groove penetrates through the bottom of the top electrode body transversely, a gas vent is formed at the upper end in the center of the slashing guide groove, one side of the top portion of the gas vent is connected with one end of a gas thread port, and the other end of the gas thread port is tangent to the outer surface of the top electrode body. Compared with the prior art, by means of the air cooling splashing proof projection welding top electrode, a welding nut can be protected effectively, the problem that a thread structure can not be assembled normally for the damage of splashing crystals in welding is solved, production procedures are reduced, the thread waste technology is abandoned, and labor cost is reduced. In addition, the air cooling splashing proof projection welding top electrode is novel and simple in structure, high in practicability, easy to implement, wide in application, low in manufacturing expenses, and capable of reducing changing frequency of the projection welding top electrode and saving production cost.
Description
Technical field
The utility model relates to welding technology field, the anti-projection welding top electrode that splashes of a kind of air cooling specifically.
Background technology
Under the overall situation that the Hyundai Motor industry develops to lightweight, each big car load factory all brings into use high-strength plate or superhigh intensity plate as the material of making the body of a motor car skeleton, and project-welding nut and plate be fixed together, this makes the application percentage of welding procedure promote significantly.When welded high-strength plate or superhigh intensity plate, project-welding nut often uses hard standard (big flow, short time) to weld, though this can effectively guarantee the requirement of strength of welding, also follows a large amount of spatters to produce simultaneously, influences the assembling of car load.In order to remove the crystal that splashes of welded nut threaded interior, can only carry out hard waste technology, consume human cost and material resources cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, transforms the structure of existing projection welding top electrode, solves welded nut generation spatter in the welding process, causes reprocessing the problem of hard waste technology.
For achieving the above object, design the anti-projection welding top electrode that splashes of a kind of air cooling, it is characterized in that: be provided with circulating water channel in the top electrode body and the gathering sill that splashes, the gathering sill that splashes laterally runs through the bottom of top electrode body, the splash central authorities upper end of gathering sill is provided with steam vent, one side at the top of steam vent is connected with an end of gas thread gas interface, and the other end of gas thread gas interface and the outer surface of top electrode body are tangent.
Circulating water channel is located at top electrode upper part of body inboard.
The axis of the axis of top electrode body, the axis of circulating water channel and steam vent is all on same straight line.
The cross section of steam vent is circular, and the diameter D of its cross section is 3mm.
The high h of top electrode body is 200mm.
The gas thread of gas thread gas interface 4 is 1/4 " straight pipe thread.
The utility model is compared with prior art, effectively welded nut is protected, solved because produce during welding splashing the crystalline fracture helicitic texture and the situation that causes normally assembling; Reduce production process, cancelled hard waste technology, reduced cost of labor; Novel simple on the structure, the practicality height is implemented easily, and applicability is wide, and manufacturing expense is low; Reduce the replacing spectrum saving of projection welding top electrode and produced required cost.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Fig. 3 is vertical view of the present utility model.
Referring to Fig. 1 ~ Fig. 3,1 is the top electrode body, and 2 is circulating water channel, and 3 is steam vent, and 4 is gas thread gas interface, and 5 are the gathering sill that splashes.
The specific embodiment
Now by reference to the accompanying drawings the utility model is described further.
The utility model comprises top electrode body 1, is provided with circulating water channel 2 and the gathering sill 5 that splashes in the top electrode body 1, and wherein circulating water channel 2 is located at the upper inner of top electrode body 1; The gathering sill 5 that splashes laterally runs through the bottom of top electrode body 1, the splash central authorities upper end of gathering sill 5 is provided with steam vent 3, one side at the top of steam vent 3 is connected with an end of gas thread gas interface 4, and the other end of gas thread gas interface 4 and the outer surface of top electrode body 1 are tangent.
The axis of the axis of the axis of top electrode body 1, circulating water channel 2 and steam vent 3 is all on same straight line.The cross section of steam vent 3 is circular, and the diameter D of its cross section is 3mm.The high h of top electrode body 1 is 200mm.
The gas thread of gas thread gas interface 4 is of a size of 1/4 " straight pipe thread.
In the process of soldering part motherboard and project-welding nut, when melting, the leg of project-welding nut can produce the situation that crystal splashes.The utility model adopts steam vent 3 and gas thread gas interface 4 interconnected modes, the compressed air of instantaneous generation is discharged during with welding, meanwhile, the effect of refrigeration has also been played in the rapid discharge of Compressed Gas to the steam vent 3 in the top electrode body 1, accelerated the to splash cooling of crystal makes it not possess adhesive capacity; By air pressure, the gathering sill 5 of splashing that the crystal that splashes can be connected along the bottom with steam vent 3 is discharged, and compressed gas knows from experience the screw thread that is full of welded nut, makes the crystal that splashes can't enter and stick to the threaded portion of welded nut.
The utility model has effectively solved because welded nut produces the situation that spatter influences the car load assembling, reduces production process, has cancelled hard waste technology, has reduced cost of labor; Novel simple on the structure, the practicality height is implemented easily, and applicability is wide, and manufacturing expense is low; Reduce the replacing spectrum saving of projection welding top electrode and produced required cost.
