Following with reference to accompanying drawing discussion embodiments of the invention.
Fig. 1 is the power circuit that is used for welding machine and arc-melting machine according to of the present invention.In the figure, reference number P represents the power circuit of welding machine, and reference number Q represents the power circuit of arc-melting machine.The power circuit of build-up welding apparatus links to each other with AC100 volt power line, and controls whole device as the printed circuit board (PCB) (PCB) of control circuit 41.
The power supply P of welding machine at first is discussed.Power supply P provides a voltage (being that welding machine and arc-melting machine are shared) to taper main electrode 8 and auxiliary electrode 20, and auxiliary electrode 20 is electrically connected with metal parts by jockey.When connecting power switch 5, power supply P works, and allows to carry out welding operation with welding material.The workman connects floor push 50 at every turn and just produces a pulse, once welds with this pulse.Adjust weldingvoltage by voltage regulator circuit 14 in the scope that approximately AC0-10 lies prostrate, voltage regulator circuit 14 is monocoil transformers, and its two ends link to each other with ac power cable by switch 5.When floor push 50 was depressed or connects, controller 41 was connected solid-state relay (SSR) 15, and capacitor C1, C2, C3 and C4 are charged.Then, controllable silicon (SCR) 16 controlled circuit 14 trigger, thereby to these capacitor discharges.The flow through former limit winding of transformer 17 of discharge current, the secondary winding of transformer 17 so low-voltage, high-current (300-1500 ampere) is flowed through.This big electric current flows to auxiliary electrode 20 from main electrode 8 immediately, so that weld.The pulse current waveform of the main electrode of flowing through 8 is shown in Fig. 1, and wherein the time of Liu Donging (1/1000-4/1000 second) is inversely proportional to current value (300-1500 ampere).If depress floor push continuously or floor push is connected continuously, so periodically repeat to discharge and recharge operation, therefore welding is carried out continuously.Utilize the digital clock of the control circuit 41 of regulating the control relay control cycle, can in the 0.3-0.5 scope of second, regulate the cycle that discharges and recharges.The power-supply device of Fig. 1 can be made compact mancarried device, and is in light weight.
If with hand operated built-up welding is partly carried out in the repairing of metal parts, main electrode 8 is insulated electrode sleeve 19 parcels so, as shown in Figure 2.On the part 3 of metal parts to be repaired 1, provide sheet type welding material 4 then, as shown in Figure 3.Workman's grasping handle electrode cover is pressed to welding material 4 with the tip of main electrode 8.Main electrode 8 is moved shown in Fig. 3 A to 3C like that, so the sheet type welding material embeds in the groove of repairing part 3.The floor push 50 of power-supply device is connected, and produces the big pulse current of 300-1000 ampere, forms soldered metal (nugget) on being repaired partly.In this case, the fusing point of the nugget of the welding material that is melted by electric current and metal parts is partially fused.When step pitch of 8 one step pitches of the main electrode diameter of main electrode 8 (step pitch corresponding) when advancing, a plurality of melt portions of welding material continuously connect together, or with the form built-up welding of multilayer.So,, finished built-up welding by form nugget, line or layer at mend with adequate thickness.Automatically carry out welding operation with machine if desired, main electrode 8 will be installed on manipulator or the similar device so, start the automatic switch 51 in the power circuit, the control whole system.
Fig. 9 A-9C represents the triangle wedge angle 3 (Fig. 9 A) of the metal parts to be repaired 1 that caused by wearing and tearing, obtuse angle or fracture.Fig. 9 B is illustrated in the state that mend has the built-up welding part 6 of q.s.For carrying out built-up welding, preferably utilize main electrode 8 with square rod (or flat rod) shape as shown in Figure 4 at the triangle wedge angle.Welding material 4 can be that thickness is the thin slice of 0.2mm and 5mm, strides to be placed on and repairs on the part.Welding material is pressed at the tip of main electrode 8, carry out tack weld, welding material is located.Main electrode 8 vertically and horizontal motion so that weld welding material bit by bit, forms a plurality of continuous soldered metal nuggets then, finishes built-up welding part 6.If the thickness low LCL of built-up welding part 6 makes the crooked also pressure welding of welding material connect material by main electrode 8, so that form the multilayer nugget so.Utilize the arc-melting machine that built-up welding part 6 is melted once more then.After melt portions is solidified, remove unnecessary built-up welding part with instrument such as scraper, and polish, so that recover triangle wedge angle 13 (Fig. 9 C) with grinder or file.
If repair the rib (edge line) of metal parts 1, then the sheet type welding material be attached on the metal parts 1 along rib to be repaired.In order to weld the pole of rolling main electrode 8 (Fig. 5).
Fig. 6 and 7 expressions adopt fine-powdered solder flux 4 ' to comprise the situation of permanent magnet 24 as welding material and main electrode 8.Welding powder is drawn onto the outer surface of the electrode that is used to carry out built-up welding.Permanent magnet 24 (or electromagnet) is installed on attraction welding powder 4 ' that part of of main electrode 8.The opposite side nonmagnetic substance of main electrode 8, the there does not attract welding powder 4 '.Owing to provide permanent magnet 24, so when the close magnetic of electrode 4 ', be drawn onto on the outer surface of electrode by an amount of welding powder of magnetic action at the welding portion that attracts welding powder 4 '.By main electrode 8 being moved to the repairing part 3 of metal parts 1, just can carry out welding operation at an easy rate.Because main electrode 8 has permanent magnet 24 in the place that attracts welding powder 4 ', have nonmagnetic substance 25 in other parts, so the welding powder 4 ' of aequum only is drawn onto the electrode district that welds.So the electrode part irrelevant with welding do not attract powder, and welding job can reliably and promptly be carried out.As shown in Figure 7,, main electrode 8 is rolled when moving, weld, and form the soldered metal parts of many point-like (nugget) continuously with the form of multilayer with powder 4 ' in order to carry out built-up welding.If the thickness low LCL of built-up welding then adds the welding powder 4 ' of additional quantity.
See Fig. 1 again, arc-melting machine Q is discussed below.The main electrode 10 of arc-melting machine and auxiliary electrode 20 may be movably coupled to the output (referring to Fig. 8) of power-supply device by cable 12 and 21.For the direction of pilot arc, main electrode 10 has taper aciculiform, and is installed to (Fig. 8) on the handle 11 by a sleeve.
For by arc-melting machine Q to melting operation again at the soldered metal 6 of built-up welding part 3 built-up welding of metal parts 1 by welding machine P, auxiliary electrode 20 contacts with the appropriate location of metal parts 1, realize to be electrically connected.After the power switch among Fig. 15 was connected the startup power circuit, by electric current conditioning equipment 42, for example two ends received the single winding transformer of AC line voltage, regulated the arc current value between 0 to 65 ampere.Main electrode 10 is near the repairing part 3 of metal parts 1 then, and the distance between electrode and the deposited metal 6 is 0.5mm, and depresses floor push 52.Action to floor push responds, and the controller indication automatic valve 31 in the printed circuit board (PCB) 41 is opened.Valve 31 is installed on the inactivity air shooter 30 that links to each other with gas tank.So argon gas flows out, near repairing part 3, causing an argon gas atmosphere.Argon gas carrier pipe 30 becomes a monolithic entity with the handle 11 of main electrode 10.Controller 41 drives the solid-state relay (SSR) 43 as switchgear, therefore in a predetermined short time (0.01-1.0 second), and the flow through input winding 44 ' of main transformer 44 of electric current.Because electromagnetic induction, produce electric current at the output winding 44 ' of main transformer 44, this electric current is through rectifier 45 rectifications becoming DC electric current, and by capacitor C5 and C6 filtering.Under the control of controller 41, high-frequency generator 47 produces a high-frequency signal, by the amplitude increase of high-frequency coupling transformer 48 these high-frequency signals, and by superposition DC electric current.Like this, between main electrode 10 and metal parts 1, applied a high-frequency signal (approximately 0.1-2MHz).In other words, depress floor push (connection) after about 0.8 second, formed conduction path between main electrode 10 and the welding material 3, therefore under the situation without any additional operations, main electrode 10 begins to produce electric arc.Produce electric arc after about 2.5 seconds, valve 31 is opened, and discharges argon gas, so that the arc-melting of built-up welding part 6 partly is wrapped in the atmosphere of inactivity gas.This operation is by controller 41 controls.In Fig. 1, the high frequency bypass that reference number 49 representatives are made up of capacitor C5, C6.If depress switch 51 (connection) always, aforesaid operations repeats in predetermined space so, and therefore continuously electric arc partly being carried out in built-up welding melts operation again.Controller 41 receives driving voltage by switch 5, fuse F and transformer T1 from ac power cable.
Single electric arc makes 5 to 10 nuggets fusings on the repairing part 3 of the metal parts 1 that is formed by the welding machine built-up welding.After the curing, form the built-up welding part 6 that single electric arc causes.Fig. 8 represents by utilizing three built-up welding parts 6 of three electric arc generations.It is overlapping that there are 1/3rd places in each arc region and adjacent arc district in its every side, partly is separated from each other to avoid built-up welding.Repeat aforesaid operations, up to waiting that repairing part is covered by built-up welding part 6.Remove redundance then, and parts are polished.
Figure 10 only is used for the power circuit of arc-melting machine when representing when welding machine and arc-melting machine each power-supply device that has itself.The circuit of Figure 10 is corresponding to the big frame Q that fences up with the single-point line.Yet the power supply of Figure 10 comprises the current detector 46 that is inserted between rectifier 45 and the transformer 48.So controller 41 can monitor arc current, if just it it is not corrected when not being desired value.Because other structure is identical with the relative section of Fig. 1 with operation, so no longer illustrated.
Though below only most preferred embodiment of the present invention is described, concerning one of ordinary skill in the art, under the prerequisite that does not depart from the scope of the present invention with spirit, can makes various modifications obviously.Term that has adopted in above specification and representation are just in order to be described rather than in order to limit, adopting such term and representation is not character representation and description or its appropriate section that is equal in order to get rid of, and will be appreciated that the only definite and restriction by following claims of scope of the present invention.
