Abstract
The utility model provides a new-type diagonal-welding machine for steel window, which adopts a three-phase welding transformer to transform the voltage and adopts a power rectifier to rectify the current, forming a direct-current welding electric source. The utility model changes the single-phase A.C. welding machine for steel window into a three-phase secondary rectifing D.C. diagonal-welding machine for steel window. The new-type diagonal-welding machine for steel window has the advantages of small input power, high power factor, stable flash welding process, close-grained lintel, good weld crater, large area of adhesion and good welding quality, realizing the three-phase power supply and avoiding the problem of imbalance of network voltage in application, suitable for the diagonal-flash welding for sealing or unsealing joint of various standard section window frames.
Description
The utility model belongs to welding equipment, is that a kind of novel steel sash is to angle welder.
At present, steel sash all is to adopt single-phase welding transformer to angle welder, obtains the low-voltage alternating current and carries out flash butt welding.Because welding current is big, the induction reactance pressure drop of welding widely different road is big, and the plant capacity factor is low, input power is high, and its capacity is at 100-200KVA.Shortcomings such as this single-phase big capacity consumer can cause imbalance of three-phase voltage when medium or small factory uses, bring the power supply capacity deficiency, and power factor is low cause adverse effect to power supply grid.When welding with A.C. welder in addition, electric current zero crossing repeatedly is unfavorable to weld heating and interface protection in the flash of light process, poor welding quality, and joint seam rate is about 80%.
Task of the present utility model is that invention a kind ofly can realize three phase supply, improves power factor, reduces place capacity, and a kind of novel steel sash that guarantees welding quality is to angle welder.
The utility model, be the single phase ac steel sash is transformed into phase secondary rectification to angle welder the direct current steel sash to angle welder, the single phase ac welding machine is by frame, guide rail, anchor clamps, transformer, weldingvoltage adjusting device, compositions such as workpiece feeder.The utility model is with three-phase welding transformer transformation, adopts the heavy-duty rectifier rectification, forms the direct current source of welding current.The three-phase welding transformer is made up of three split type single-phase transformers or three-phase three stem stem formula transformers, and rectifier adopts the rectification of high-power combined type silicon diode.
Accompanying drawing 1 is a structural representation of the present utility model.
Be described with reference to the accompanying drawings structure of the present utility model.
As shown in the figure, (1) frame; (2) three-phase welding transformer; (3) rectifier; (4) direct current welds widely different road; (5) guide rail; (6) decide plate; (7) decide anchor clamps; (8) moving anchor clamps; (10) vertical transmission mechanism; (11) Pneumatic hydraulic damp type driving mechanism.
Welding transformer and heavy-duty rectifier are formed six phase half wave rectifying circuit, and the direct-flow no load voltage that jaw obtains is:

1For the welding transformer primary side is received the voltage effective value of electrical network, W
1Be the number of turn of primary winding, and every phase two circles of transformer secondary output winding; When six phase half-wave rectifications, calculate number of turn W
2=1.By last two formulas as can be known, change W
1Just can realize output dc voltage u
dAdjusting.W
1Regulative mode can be tapped or the series and parallel formula.Welding transformer and rectifier also can be taked the three phase half wave rectification mode.
When carrying out steel sash,, and be that closed joint also is non-closed joint according to window frame sectional area size to welded corner joint, select welding transformer to regulate progression, obtain suitable commutating voltage, regulate feed rate simultaneously, workpiece can be clamped in the anchor clamps then, starting switch welds.In the flash welding termination process, current of welding transformer is by rectification, and to weld zone output D.C. high-current, the heating through the flash of light stage enters upset, obtains superior in quality steel sash diagonal angle joint.
The utility model, owing to adopted direct current flash butt welding method welding steel sash, so that the flash of light process stabilization, lintel is fine and closely woven, the weld bond protective effect is good, no field trash in the joint, bonded area is big, thereby has improved welding quality. Simultaneously, because power factor improves, input power descends greatly, has realized three phase supply, has avoided the unbalanced source voltage problem. Can finish the sealing of various standard sections window frame or the diagonal angle Flash Butt Welding of closed joint not.
Claims (3)
