Embodiment 1

[0018] Such as figure 1 As shown, the present invention first connects the electric welding machine to the power supply, opens the water inlet switch on the circulating cooling water tank, and when the cooling circulating water passes through the water flow transmitter, connects the controller to allow the equipment to enter the working state; when the cooling water switch is closed When there is no cooling water passing through the water flow transmitter, the controller cuts off the power, and the welding tongs cannot work normally when the power is cut off; if the circulating cooling water tank suddenly cuts off water during work, the water flow flood preventer will immediately transmit the signal to the controller and issue a warning Inform the staff, and at the same time, the controller automatically cuts off the power until the cooling water returns to normal, and the whole equipment also returns to normal, and re-enters the working state; wherein the electric welding mach...

Embodiment 2

[0020] 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 control loop is connected with the controller. 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 burned out due to excessive tempera...

Embodiment 3

[0022] 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 an electric welding machine used in an automobile production workshop 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 It is the welder who has a relatively high risk of electric contact. 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 resc...

Abstract

The invention discloses an application method of a workshop electric welding machine. Firstly, the electric welding machine is communicated with a power supply; a water inlet switch on a circular cooling water tank is opened; after cooling circulating water passes through a water flow pinger, a communication controller enables equipment to enter a working state; when a cooling water switch is closed, no cooling water passes through the water flow pinger, the controller cuts off the power supply, and a welding clamp cannot normally work due to power failure; and if the circular cooling water tank suddenly breaks water in working, a water flow flood preventer can immediately transmit a signal to the controller, an alarm is given to workers, the controller automatically cuts off the power supply until the cooling water recovers normally, and the whole equipment recovers normally to enter the working state again.

Description

technical field [0001] The invention relates to glass processing auxiliary equipment, in particular to a method for using an electric welding machine in a workshop. 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...
