Embodiment 1

[0017] Such as figure 1 As shown, this embodiment includes a transformer, a controller, a circulating cooling water tank, a water-cooling cable and welding tongs. The transformer is connected to the circulating cooling water tank and the controller respectively. The water-cooling cable passes through the circulating cooling water tank. It is connected, and also includes a water flow preventer arranged in the circulating cooling water tank, and the water flow preventer is connected with the controller. When the equipment is powered on, turn on the water inlet switch on the circulating cooling water tank. When the cooling circulating water passes through the water flow transmitter, turn on the controller to let the equipment enter the working state; when the cooling water switch is turned off, no cooling water passes through the water flow transmitter. The communication device, the controller cuts off the power supply, and the welding tongs cannot work normally when the power is...

Embodiment 2

[0019] Such as figure 1 As shown, in this embodiment, on the basis of Embodiment 1, the water flow flood control device includes a temperature sensor, a water level sensor, an alarm and a control loop, and the control loop is connected to the temperature sensor, the water level sensor, and the alarm respectively. The water flow preventer is connected with the controller through the control circuit. The control loop is the command center of the water flow preventer. When the water level sensor detects that the water level in the circulating cooling water tank is low, it will transmit a signal to the control loop, and the control loop will control the alarm to sound a buzzer; if the water level in the circulating cooling water tank When the temperature rises sharply due to lack of water, the temperature sensor will transmit the signal to the controller through the control loop, and the controller will directly cut off the power supply to prevent the water-cooled cable from being...

Embodiment 3

[0021] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment also includes an electric shock prevention device arranged on the input end of the transformer. When the welding machine is unloaded, the voltage of the DC welding machine is 55-90V, and the voltage of the AC welding machine is 60-80V, both of which exceed the safe voltage value, but because the voltage is not very high, it is often ignored, especially the risk of electric contact of welders bigger. According to the calculation, when the no-load voltage of the welding machine is 70V, the human body is operating in a humid place, and the protective equipment is not properly worn. At this time, the human body resistance RR is about 1600Ω. If the welder's hand touches the jaws, the current IR = V / RR=70 / 1600=0.044A=44MA, under the action of this current, the welder’s hand will convulse, causing ventricular fibrillation. If the rescue is not timely, there will be a risk of death. The anti-shock device ...

Abstract

The invention discloses an electric welding machine with an early warning function. The electric welding machine with the early warning function comprises a transformer, a controller, a circulating cooling water tank, a water cooling cable, welding pincers and a water flow flood control device, wherein the transformer is connected with each of the circulating cooling water tank and the controller; the water cooling cable penetrates through the circulating cooling water tank; the welding pincers are connected with the transformer through the water cooling cable; the water flow flood control device is arranged in the circulating cooling water tank and is connected with the controller. Through the arrangement of the water flow flood control device, the transformer and the water cooling cable are prevented from burnout because of cooling water; the service life of the water cooling cable is greatly prolonged; the workload of maintenance staff is also reduced.

Description

technical field [0001] The invention relates to the field of electric welding, in particular to an electric welding machine capable of early warning. Background technique [0002] In the production process of automobile and other panel products, welding machines and welding robots have become the key equipment to improve production efficiency and ensure product quality. According to the working characteristics of the equipment, taking corresponding protection measures can ensure the safety and energy saving of the equipment Effect. The welding machine has greatly improved the productivity of the enterprise, and the product competitiveness has also been greatly improved. However, in the process of using, many shortcomings have also been found. The reason is that the service life of the water cable of this equipment is too short, the damage is too fast, and the replacement frequency is too high. This not only causes the equipment to be shut down frequently for maintenance, w...
