Description
Technical field
The utility model relates to a kind of pressure control device, particularly relates to a kind of electric resistance welding pressure control device.
Background technology
Electric resistance welding, primarily of workpiece or resistance, completes by producing heat during electric current.Heat Q=I
2rt, this shows, the controling parameters of electric resistance welding is divided into usually: the size (I) of secondary welding welding current, current duration (t), contact resistance (R).The above two provide control by welding controller, and contact resistance cannot directly control.Contact resistance is by resistance, surface appearance, the thrust of workpiece itself.The change of thrust directly can have influence on the size of contact resistance, sometimes difference tens times.
Summary of the invention
The purpose of this utility model is just to provide a kind of electric resistance welding pressure control device to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises welder, pressurized cylinder, top electrode, bottom electrode, pressoreceptor, the first workpiece and second workpiece, described welder is connected with described top electrode and described bottom electrode respectively by cable, the upper end of described top electrode is provided with described pressurized cylinder, be provided with described first workpiece and described second workpiece between described top electrode and described bottom electrode, described pressoreceptor is arranged at described top electrode one end near described first workpiece.
Further, described first workpiece is positioned on described second workpiece.
Further, described welder comprises welding controller and welding transformer, described welding controller and the communication connection of described welding transformer.
Further, described welding controller is connected with described pressoreceptor telecommunications.
Further, described welding transformer is electrically connected with described top electrode and described bottom electrode respectively.
The beneficial effects of the utility model are:
The device of the utility model thrust by quantifying, detects in real time and controls secondary discharge opportunity, thus realizing effective and reasonable welding, guarantee steady production; The utility model has that structure is simple, stable performance and service life longer advantage.
