Discussion on the application and maintenance of spring upset forging welder

Move the handle counterclockwise to separate the two jaws. The positioning of the moving clamp is located on a plane of the outer edge of the eccentric on the joystick. Only when the plane on the eccentric bears against the ejector can the clamp be activated. Positioning. Step on the pedals, let the jaws open, install the workpiece, loosen the pedals and clamp the workpiece. When clamping the weldment, leave a gap between the workpieces according to the size of the weldment section to relax the pedals. The workpiece is clamped and the handle is pulled clockwise (relaxed) so that the ends of the workpiece are in contact with each other and are pressed against each other under the action of the spring force. Observe the relative position of the ejector pin and the switch piece of the welding limit switch (also called the upset switch) in the upper part of the upper part of the fixed fixture. The distance between the two should be a certain distance. The distance should be heated by the workpiece. When the welded joint is formed, the copper piece of the limit switch can be opened and the weld flash formed by the welding meets the requirements. Press the welding button switch, turn on the welding transformer power supply to energize the welding piece, heat the end of the welding piece, and perform the upsetting under the action of the top forging force, when heating to a certain extent by the action of the limit switch. Step on the pedal, loosen the jaws, and remove the workpiece. According to the requirements of the weldment, choose whether to temper or not. The same section weldment tempering specification (ie, energization time and tempering current) is smaller than the welding specification.

When using the operation precautions, the test welding of the workpiece should start with a small specification and gradually adjust to the appropriate according to each item. The degree of firmness of the welded joint is judged by the number of times the workpiece is repeatedly bent after the test welding of the same specification workpiece. Considering the influence of the welding current shunt, the specification for the welding of the annular workpiece should be slightly larger than that of the straight section of the same section. When adjusting the adjusting screw of the limit switch, pay attention to observe the relative position of the end of the switch ejector and the switch piece in the inspection window (the switch piece should be opened at the end of the welding), otherwise the switch piece may be deformed by the top pressure. Normal use of the welder. During the welding operation, the hammer and other heavy objects cannot be used to strike and fix the surface of the fixture and force the workpiece still clamped to the jaws to avoid affecting the normal use of the welder. Conductive debris that may cause a short circuit in the welding circuit should not be placed around the fuselage body. During the welding process, the welder jaws, oxides on the electrode surface, welding slag and other deposits should be cleaned frequently to keep the jaws and electrodes clean and the workpiece and electrode are well conductive. After the welding operation is finished, the two electrodes should be at a minimum distance (ie, the handle should be loosened clockwise) to avoid fatigue damage caused by the internal spring being under tension or pressure. The contact surfaces of all moving parts of the welder must always be well lubricated and freely movable. The power supply should be cut off in time before the welding operation is completed, deactivated or repaired to ensure safety. Common faults and repairs of the welder In the welding process, if there is a fault, it should be immediately shut down for maintenance. After the fault is eliminated, confirm that the welder is normal before it can be put into operation. Common faults and maintenance methods for the welder.
