High frequency oscillator

The core component of high-frequency trapaulin welding machine is high-frequency oscillator. High-frequency oscillator is mainly composed of oscillator box, power transformer, rectifier circuit, coupling capacitor and oscillator tube.

The working principle of high-frequency oscillator is to convert the low-voltage power supply provided by power transformer into DC power supply through rectifier circuit, and then into high-voltage power supply through HF transformer. The high-voltage power supply is transmitted to the oscillating tube through the coupling capacitor, and the oscillating tube converts the direct current into high-frequency current, which is finally transmitted to the surface of the processed material through the electrode.

Electrode

Electrode is another important part of the high-frequency canvas welding machine. The electrode is responsible for transmitting high-frequency current to the surface of the processed material and welding the material by local heating.

The electrode usually consists of two parts, namely, the electrode head and the electrode bottom plate. The electrode head is responsible for concentrating high-frequency current to the welding site, while the electrode bottom plate is responsible for fixing the materials around the welding site to avoid displacement or deformation during welding.

The shape and material of electrode will directly affect the welding quality and efficiency. According to the characteristics and shape of the processed material, the shape of the electrode can be selected as different shapes such as circle, square and shuttle. The material of the electrode needs to have high conductivity and high wear resistance. Common materials are copper, copper alloy and platinum.

Welding technology

The welding process of high-frequency canvas welding machine can be divided into the following steps:

Step 1 prepare for work

Before welding, it is necessary to prepare the processed materials and their auxiliary components. In addition, it is necessary to install the electrode correctly and adjust the distance and pressure of the electrode to ensure the welding quality and efficiency.

Step 2 stabilize the pressure

When the electrode contacts the surface of the processed material, it is necessary to ensure the stable pressure of the electrode. Stable pressure can ensure the contact quality between the processed material and the electrode, thus affecting the welding quality and efficiency.

3. Start welding

High-frequency canvas welding machine uses the principle of instantaneous heating to complete the welding process. During welding, the electrode tip will produce high frequency and high temperature, which will quickly heat the surface of the processed material to above the melting point. The molten material then cools and solidifies, thus completing the welding.

4. Check the weld

After welding is completed, it is necessary to check the weld. Checking the weld can confirm the welding quality and effect and analyze and improve the welding process.

Summary

High-frequency canvas welding machine is a professional welding equipment for canvas, plastic, leather and other materials. It uses high-frequency oscillator and electrode to convert electric energy into high-frequency and high-voltage current, and completes welding by instantaneous heating. Longgao cycle canvas welding machine has the advantages of simple process principle, convenient operation and high welding quality, and has a wide application prospect.
