Variable frequency multi head spot welder

Variable frequency multi head spot welder

Introduction to this machine

This machine is a frequency conversion gantry type row welding machine, the transformer is AC type, and the electric control box is frequency conversion type. It can ensure both welding strength and stable welding current. Moreover, it has little impact on the power grid and saves electricity, which is very suitable for the situation that there are many factories and machines with insufficient power grids. It is the combination of AC welding machine and medium frequency welding machine.

Gantry welding machine host

1. The input voltage is 380V, the power is 150KVA * 2, there are 18 three-layer cylinders, the internal width of the machine is 2300MM, and the effective welding width is 2000MM. Welding row welding die is equipped with 100MM long chrome copper electrode.
2. The main transformer is made of full red copper coil, high grade silicon steel, powerful transformer, strong current, and the maximum short-circuit current is 32000A And there is water circulation cooling, temperature control device, comprehensive protection of the machine can work for a long time with high current. Overload will automatically power off.

3. The control box is two frequency conversion control boxes. The control frequency of the frequency conversion controller is 5KHZ, with high control accuracy and stable current, so as to ensure that the welding process reduces spatter and the welding effect is better.

4. The cylinder is a three-layer adjustable cylinder, which is fast, powerful and easy to adjust. Taiwan Yadeke solenoid valve, stable and durable.

2 sets of upper and lower exchange die for gantry welding machine automatic feeding rack

1. Two sets of mesh welding pushing dies, and two sets of dies are exchanged up and down for welding. Save time and space. The pushing die is used to install the welding die, not the clamping die that can be directly welded.

2. The mold installation space is a maximum of 2m wide * 1.5m long mesh.

3. There are 2 sets of servo motors and 1 set of PLC+human-machine interface. The design is user-friendly and easy to adjust.

4. During operation, the machine automatically sends the mold for welding, automatically returns, and automatically ejects the mold.

5. The widened and thickened aluminum profile support is stable and solid, and easy to adjust.

Overview:

The equipment pays attention to multi-point welding, saving time, labor and high efficiency. Generally customized according to product conditions and customer requirements.

By transformer:

it can be made into double transformer type, single transformer type, medium frequency type and frequency conversion type.

Other names

According to the number of force doubling cylinders:

it can be made into 4-20 cylinders.

According to the product size: it can be made, 1m wide and 1.35M long. Or 1.5m wide, 1.35M long, or 2m * 1.35M, many kinds. If it is a loading cabinet outlet, it is better to make it within 1.5m wide * 1.35M long.

According to the feeding mode:

it can be pushed manually, feed the front and rear dies automatically, and exchange the die feeding up and down automatically.

Compared with the common power frequency AC controller, the inverter controller has the following advantages

1. The control frequency of the variable frequency AC controller is 5KHZ, with high control accuracy and stable current, so as to reduce spatter during welding;
2. Because the variable frequency AC welding machine uses the power frequency transformer, it is very simple and convenient to transform the power frequency welding machine. It is only necessary to replace the original power frequency AC controller with the variable frequency AC controller;
3. Aluminum, galvanized sheet, high tension steel, stainless steel, magnesium alloy, carbon steel and titanium can be welded with good welding effect;
4. The three-phase 380V AC power input solves the problem of unbalanced three-phase power grid input, with high power factor;
5. Because the intermediate frequency transformer used for the intermediate frequency DC controller has a rectifier diode, and there is a 0.7V pipe voltage drop on the diode, which will bring power loss. The greater the current, the greater the power loss on the diode. Therefore, the variable frequency AC controller has more advantages in high-power applications.
