Description
Technical field
The utility model relates to a kind of Workshop Production processing auxiliary equipment, specifically refers to a kind of workshop electric welding machine.
Background technology
In the production process of the products such as petrochemical industry; welding machine, welding robot have become the key equipment of enhancing productivity and guaranteeing product quality; for the operating characteristic of equipment, take corresponding safeguard measure, can make equipment obtain safety guarantee and energy-saving effect.Welding machine, promoted to a great extent the productivity of enterprise, and product competitiveness is also greatly improved.But in use, also found a lot of deficiencies, reason is that the water power cable life cycle of this equipment is too short, it is too fast to damage, and replacement frequency is too high.So not only cause the frequent shutdown maintenance of equipment, impact is produced, but also has increased maintenance personal's working strength, has increased maintenance cost simultaneously.Operator is when the equipment of use, because production on-site environment is complicated, wait a variety of causes, the importance of ignoring sometimes cool cycles penstock, does not open completely or just forgets and open at all, cause water-cooled cable because of can not obtain effectively cooling damage too fast.
Before using welding machine welding, first should guarantee there are enough cooling water flow supercooling systems.At present, most manufacturer is only provided with cooling device on the water-cooled cable of welding machine, but under working long hours, the miscellaneous parts such as transformer can generate heat equally and cause the temperature of internal structure sharply to rise, if the consequences such as transformer burns out can occur in processing not in time.
Utility model content
The utility model is by arranging a kind of workshop electric welding machine, and the transformer that solves traditional welding machine such as easily burns out at the problem, reaches the object that reduces welder fault rate.
The purpose of this utility model reaches by the following technical programs:

When welding machine is worked, transformer can produce larger heat equally, if process not in time, also can cause transformer impaired, and the radiator fan of setting can be taken away the amount of heat of its generation, guarantees that the working stability of transformer carries out.
Further, described current flood control device comprises temperature sensor, water level sensor, alarm and control loop, and described control loop is connected with temperature sensor, water level sensor, alarm respectively, and control loop is connected with controller.Control loop is the command centre of current flood control device, when water level sensor detects water level in circulating cooling water tank when lower, signal can be transferred to control loop, and control loop is controlled the alarm prompting of sounding a buzzer; If circulating cooling water tank internal cause is lack of water while causing temperature sharply to raise, temperature sensor can transfer to controller by control loop by signal, controller is directly cut off the electricity supply, and avoids excess Temperature and causes water-cooled cable to burn out, and has extended the service life of water-cooled cable.
Further, as preferably, described temperature sensor is PT100 temperature sensor.PT100 temperature sensor is a kind of instrument that temperature variable is converted to transmissible normalization output signal.PT100 is platinum resistance thermometer sensor,, and its resistance is with the direct ratio that is varied to of temperature.The resistance of PT100 and variations in temperature are closed: when PT100 temperature is 0 ℃, its resistance is 100 ohm, and in the time of 100 ℃, its resistance is about 138.5 ohm, and its resistance can increase along with temperature rises to form at the uniform velocity.When the water temperature in circulating cooling water tank changes, the change in resistance amount of PT100 temperature sensor, is adjusted by control loop to control loop by wire transmission.
Further, described temperature sensor is arranged on water-cooled cable.Temperature sensor is provided with the restriction of maximum temperature, and when surpassing maximum temperature, temperature sensor will send signal to control circuit, and alarm sends alarm; Temperature sensor directly contacts with water-cooled cable, can effectively prevent from causing temperature sensor displays temperature to occur larger error because spread heat in circulating cooling water tank is uneven, thereby false temperature is provided.
Further, described radiator fan is provided with protective cover.When radiator fan is placed in welding machine inside, can take more inner space, so usually fan is placed on transformer top.For avoiding external fan welder to be caused to security incident or prevent that extraneous dust, foreign material from entering in fan, protective cover is set on fan and can guarantees that the stable of welding job carries out.
Further, as preferably, the wire of described water-cooled cable is enamel-covered wire.Because insulate between every enamel-covered wire, conduction medium, high frequency electric current, surface generation kelvin effect online, compares with cross section water-cooled cable with other, and during by identical electric current, caloric value is few; Of enamel-covered wire, make the wire of water-cooled cable, can improve the service life of water-cooled cable, because the wire long period of soaking of water-cooled cable is in water; working environment is very severe; enamel-covered wire has paint film protective layer, can play antisepsis, and be 1.5～2 times of copper bare wire its service life.
The utility model compared with prior art, there is following advantage and beneficial effect:
1, the utility model comprises transformer, controller, circulating cooling water tank, water-cooled cable and soldering turret, described transformer is connected with circulating cooling water tank, controller respectively, water-cooled cable is through circulating cooling water tank, soldering turret is connected with transformer by water-cooled cable, also comprise the current flood control device being arranged in circulating cooling water tank, described current flood control device is connected with controller, and the top of described transformer is also provided with radiator fan.When welding machine is worked, transformer can produce larger heat equally, if process not in time, also can cause transformer impaired, and the radiator fan of setting can be taken away the amount of heat of its generation, guarantees that the working stability of transformer carries out.
2, radiator fan of the present utility model is provided with protective cover.When radiator fan is placed in welding machine inside, can take more inner space, so usually fan is placed on transformer top.For avoiding external fan welder to be caused to security incident or prevent that extraneous dust, foreign material from entering in fan, protective cover is set on fan and can guarantees that the stable of welding job carries out.
