Description

The electric welding machine energy saver

One, technical field

The utility model relates to electric welding equipment, particularly a kind of saves energy, improves the electric welding machine electric welding machine energy saver in service life.

Two, background technology

Welding is the modern a kind of basic processing method of making, it is widely used in the industrial and agricultural production of China, in the family of electric welding machine, advantage such as low and easy maintenance is used widely owing to arc welding transformer condenser discharge welder cost, but big (the about 0.85-1.3kwh of arc welding transformer condenser discharge welder open circuit loss, traditional arc generator condenser discharge welder is more up to about 1.5-4.2kwh) arcing time factor is low, generally in that (workman is in practical operation about 50%, generally be lower than dwell time weld interval, the ratio of arcing time factor-weld interval and working time, the so-called working time be weld interval and non-weld interval sum, cycle as the working time is 10 minutes, so the meaning of arcing time factor 50% be exactly weld interval be 5 minutes continuously, stopping weld interval is 5 minutes, fan does not stop), this has caused very big waste with regard to the energy of giving country, and electric welding machine is short service life, therefore, solve the energy-conservation of arc welding transformer condenser discharge welder, the problem that increases the service life just seems and is even more important.

Three, utility model content

At the problems referred to above, the purpose of the utility model just provides a kind of power economizer for electric welder, can effectively solve the energy-conservation of electric welding machine and the problem that increases the service life, the technical scheme of its solution is, the power supply of employing electric welding machine is connected with external power cord by the power switch of A.C. contactor and series connection, the connecting and disconnecting of welder power are by the microswitch control that is installed on the welding clamp handle, when needs weld, press the microswitch key on the welding clamp handle, the A.C. contactor adhesive, power connection, when not welding, the openhanded pincers that snap, microswitch disconnects immediately, A.C. contactor discharges, cut off welder power, thereby thoroughly eliminated the time of electric welder no-load operation, the problem that has solved the electric welder no-load power consumption effectively and prolonged service life, in view of the above, its structure of the utility model is, comprise power switch, fuse, microswitch, A.C. contactor, electric welding machine and soldering turret are formed, the primary source coil of electric welding machine is connected with the main contact of A.C. contactor (km), the main contact of A.C. contactor is connected with power switch, electric welding machine links to each other with soldering turret, the coil of microswitch and A.C. contactor joins, and is serially connected with fuse in the control circuit of microswitch and ac contactor coil.

The utility model has thoroughly solved the problem of electric welder no-load power consumption, the also corresponding working time that reduces electric welding machine, improved the service life of electric welding machine, can save the bigger energy for country, add that this apparatus cost is cheap, simple in structure, easy and simple to handle, advantages such as easy production necessarily have good market prospects and economic benefit.

Fig. 2 is a soldering turret vertical view of the present utility model.

Fig. 3 is an electrical equipment control schematic diagram of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

By shown in Figure 1, the utility model is to comprise power switch 1, fuse 2, microswitch 3, A.C. contactor 4, electric welding machine 5 and soldering turret composition, the primary source coil of electric welding machine 5 is connected with the main contact of A.C. contactor (KM) 4, the main contact of A.C. contactor 4 is connected with power switch 1, electric welding machine 5 links to each other with soldering turret, the coil of microswitch 3 and A.C. contactor 4 joins, and is serially connected with fuse 2 in the control circuit of microswitch and ac contactor coil.

Said soldering turret is by shown in Figure 2, its structure is, include soldering turret body and handle, there is the handle that is made of main handle body 8 and secondary handle body 7 at soldering turret body 6 rear portions, and microswitch 3 is installed on the main handle body 8, and an on ﹠ off switch 9 movable up and down is arranged on the microswitch 3, there is binding clip 11 front portion of soldering turret body 6, binding clip 11 is made up of upper and lower two parts, pincers is housed 10 on top and the soldering turret body, clamp 10 and 6 of soldering turret bodies spring 12 is housed.

Concrete work operating position of the present utility model is that during use, the power supply of electric welding machine is by the power switch (QS) 1 and external power cord L of A.C. contactor and series connection ₁, L ₂Connect (seeing shown in Figure 3), on the binding clip 11 welding rod is arranged, be used to connect the power supply welding, first power turn-on switch 1 before welding job is pressed microswitch key 9 again during welding, at this moment microswitch 3 closures, the coil of A.C. contactor 4 gets electric adhesive, its main contact closure, welder power is connected, and can weld, when not welding, welder's the openhanded pincers that snap, on ﹠ off switch 9 is opened automatically, the contact of microswitch 3 disconnects, and has cut off the circuit of A.C. contactor 4 coils, the coil losing electricity of A.C. contactor 4 discharges, its main contact disconnects, and cuts off welder power, and electric welding machine quits work.
