Description
Technical field
The utility model relates to various medium frequency inverter formula resistance welders.
Background technology
The general resistance welder of China for AC power frequency formula (being AC 50HZ) because resistance welder is the direct short-circuit by welding transformer when welding, produce big electric current after, convert electric energy to heat energy, and make the sheet material fusing form weldering nuclear.So, the method for this interchange welding, the one, more original, two are to use electric power bigger, and the 3rd, general low carbon steel plate can only be welded, and modern metal materials such as various clad steel sheets, alloy-steel plate, corrosion resistant plate and high-strength steel sheet can not be welded.
So, fast development of modern industry, continuous progress in science and technology, the continuous appearance of various metal materials, the various energy constantly in short supply.The solder technology of the metal material of, more complicated relatively poor to various novel solderabilities and equipment energy-conservation just proposed new requirement.
Summary of the invention
The purpose of this utility model provides a kind of both energy-efficient, again the medium frequency inverter formula resistance welder that can effectively weld the metal materials such as various clad steel sheets, alloy-steel plate, corrosion resistant plate and high-strength steel sheet in modern times.
The technical solution of the utility model is: be made up of the cooling device in welding machine body, the body, welding head, be provided with welding transformer in the welding machine body, body and head flexibly connect by a rotating disk, are provided with retaining mechanism on rotating disk.
Comprise by the 50Hz inversion being the IGBT inverter of 1000Hz in the described welding controller circuit, the input of IGBT inverter connects current rectifying and wave filtering circuit, and output connects welding transformer.
The dust seal steel wire ball road that aluminium alloy specialty is made can 360 ° of rotation rotating disks that revolve commentaries on classics, and have two rotating disk lockers.
The high-strength aluminum alloy caliper, the interchangeable tong arm of modularization closed type.
Also be provided with the U-shaped protection ring on head, the head side is provided with support, is connected with the suspension type suspension rod on the support.
On fuselage, be provided with a pair of operating grip.
Head of the present utility model is adjustable, makes operation reliable, easy to use, the reliability height.It also has following advantage:
1, adopts the medium frequency inverter technology
The medium frequency inverter resistance welder is to have adopted state-of-the-art semiconductor devices IGBT to change line voltage.Its basic principle is:
Three-phase alternating current 380V, 50Hz---elementary rectification 600V direct current---------is direct current by secondary commutation---workpiece welding that becoming single-phase 1000Hz by the IGBT inverter exchanges by the intermediate-frequency transformer transformation, by adjusting and current boost fast fast, thereby effectively, stably export welding energy.
2, stability of the welding quality height
Because the welding current adjustment is accurately to control with the intermediate frequency (response speed that is equivalent to Millisecond) of per second 1000 times, is more than 20 times of traditional SCR type resistance welder control accuracy, thereby has improved the stability of welding quality greatly.
3, reduce energy loss
China's resistance welder industry and development and national economy are closely bound up.Particularly automobile, manufacturing developing rapidly such as system jar etc., production scale constantly enlarges, so that transformation station power supply transformer capacity deficiency, number transformer certainly will will be increased, factory building will enlarge like this, correspondingly increase equipment such as high and low voltage switch cabinet again, increase investment.If but with inversion direct current electric resistance welding machine, problem has just solved.As 250KVA single phase ac mash welder,, only need 80KVA just much of that when selecting the medium frequency inverter resistance welder for use.Automobile factory's 160KVA suspension type ac spot welding machine with the most use and for example is when the resistance welder of selecting for use the inversion principle to make only needs 44KVA just much of that.The anti-sloshing baffles of China's aerospace container adopts 3X100KVA phase secondary rectification mash welder to weld nearly 4 tons of welding machine weight for another example, when the inversion direct current electric resistance welding machine of selecting for use the inversion Fundamentals of Welding to make, only need 150KVA just much of that, the about 800kg of welding machine weight, and so on.So producing powerful inversion direct current electric resistance welding machine, domestic many manufacturing industry an urgent demands at present become inexorable trend.
4, water saving, economize on electricity, energy-conservation
Medium frequency inverter formula resistance welder water route connects has all adopted waterproof sealing, ways of connecting, and main Inlet and outlet water fast that independent valve control, handled easily are all arranged.General old-fashioned ac spot welding machine discharge is generally 30～40L/min, and this welding machine only needs the discharge of 8～12L/min, has significantly reduced water consumption.
The characteristics of this welding machine maximum are to save a large amount of energy.It is by increasing considerably the virtual value of welding current, and the welding power factor is more than 98%, has improved manyly than general traditional SCR resistance welder 60% efficient, so the electricity power cost of product welding significantly reduces.And, because adopt the three-phase equally loaded, do not cause the spike overload mutually to any independent one, satisfy preferential ower rate requirement.
Secondary and the soldering turret of this welding machine is direct-connected, and old-fashioned in the past welding machine couples together the two with cable, so this welding machine just greatly reduces the loss of electric current, the Weldability of its 80KVA is equivalent to the Weldability of 250KVA ac spot welding machine, and 44KVA is equivalent to Weldability of 160KVA suspension type ac spot welding machine or the like.One of inverter type welder 1 year just can be saved more than 20,000 yuan of the electricity charge, almost save the 2/3-3/4 energy, now many factories are automobile factory particularly, all expanding the scale of production, the power transformer off-capacity, if but use this resistance welder instead, the power transformer capacity is just much of that, because the power consumption of 3 playscript with stage directions welding machines, be equivalent to the power consumption of an old-fashioned ac spot welding machine, importantly welding quality is far superior to old-fashioned AC welding set again.
5, human oriented design
The medium frequency inverter resistance welder uses flexile modularization, hommization structural design, allow use, safeguard more general convenient.
The incorporate structure of welding gun and transformer, volume is little, and is in light weight;
The rotation rotating disk of the dust seal steel wire ball road that aluminium alloy specialty is made can 360 ° of rotations, are not subjected to spatial constraints, and have two rotating disk lockers, flexible operation;
The high-strength aluminum alloy caliper, the interchangeable tong arm of modularization closed type;
The protection of band U-shaped;
The switchable double operation handle of double-button, program that meets ergonomic, but and multiposition can regulate installation; Blossom type handle fixed head is according to easy to operate any installation;
The multistage cylinder of the auxiliary stroke of band, stroke ratio is stepless adjustable;
Dual chain temperature protection;
The suspension type suspension rod of Tape movement location can place welding gun 360 ° of rotation uses arbitrarily;
6, security protection
The medium frequency inverter resistance welder has added a location insulation sleeve in main power source wiring place, has strengthened the insulating properties of welding machine, and the whole transformer of welding machine all by about two protective covers.
7, C type and X type
The medium frequency inverter resistance welder is divided into C type and X type, can change according to the spacing L between customer requirement two arms.
