The single-rib brake shoe seam frequency welding machine adopts intermediate frequency welding technology. The intermediate frequency transformer has the advantages of small size, output rectification, beautiful appearance, convenient maintenance and installation, etc. Since the welding power is direct current, the loss in the heating process is small, so as to achieve the effect of saving electricity ( Usually 30% less than ordinary power frequency). The pressurized welding cylinder of the equipment adopts the brand wear-resistant sealing ring, and the double-layer stroke adjustable structure increases the welding stability and shortens the adjustment time for changing the product model.

HOW DOES MEDIUM FREQUENCY WELDER WORK?

1. Pressurization: when the workpiece is welded, the electrode is aligned with the welding position, the rigid pneumatic switch is started, the working air valve is opened, and the compressed air enters the pressurized cylinder to drive the dynamic welding mechanical movement through the mechanical device to make the electrode press the workpiece. This process is called pressurization.

2. Welding: the thyristor in the controller is connected and opened, and the primary side of the transformer receives controllable primary current; The secondary side of the transformer generates welding current, which reaches the electrode through the secondary circuit to energize and heat the workpiece. This process is called welding. The process parameters are welding current, welding time and electrode pressure.

3. After welding is powered on, the crystal valve tube is turned off, and the workpiece is not powered on. At this time, the electrode also presses the workpiece tightly, and the molten metal is cooled under the action of electrode pressure to crystallize to form a dense crystal. This process is called cooling or forging, and the process parameters are maintenance time and electrode pressure.

BENEFITS OF MEDIUM FREQUENCY WELDER

The device is small in size, which greatly saves space. Adopt output rectification technology to save energy consumption. The use of end-face friction conduction increases production efficiency. Adopt clamping system to ensure welding quality.

The structure of the double stroke can be adjusted, thereby shortening the adjustment time for changing product models. Three sets of discharge pulses can be set up individually and used individually or in any combination. The equipment adopts three-phase power input with high working frequency.

The transformer loss is small, and the energy saving effect is remarkable. Preheating current, welding current and tempering current can be set, which effectively solves the problems of spatter during welding and quenching after welding. The three discharge pulses can be set individually, used individually or in any combination. For a 1.5mm thick panel and 4-5 solder joints, about 6000 products can be produced in an average of 10 hours (data provided by cooperative customers).

ADVANTAGES OF MEDIUM FREQUENCY WELDER

Intermediate frequency seam welding technology

The intermediate frequency seam welding technology is independently developed by our company. The equipment panel adopts a manual crank structure, which greatly shortens the adjustment time. When there is no material, the equipment will automatically stop and alarm.

Arbitrary adjustment of position

The panel push claw is made of alloy steel by vacuum quenching, and the structure of the panel pusher adopts Taiwan AirTAC SC type cylinder. The push distance and position can be adjusted arbitrarily to improve the usable range. There is a panel detection device on the feedback electrical terminal.
