Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a multi-purpose pulse argon arc welding machine. Background Art

[0002] The existing pulse argon arc welding machine has the following problems due to the limitations of the structural setting:

[0003] 1. Due to the different control methods and output characteristics of cutting and welding, high voltage accidental electric shock and short circuit are prone to occur, and the switching between welding and cutting functions cannot be achieved safely and reliably.

[0004] 2. The reactor and high-frequency coupler are connected in series in the welding output circuit of the welding machine, but the high-frequency coupler only works at the moment of arc ignition.

The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Below, the present invention is further described with reference to the accompanying drawings and specific embodiments:

[0033] like Figure 1-3 As shown, a multi-purpose pulse argon arc welding machine includes a chassis 1, wherein the chassis 1 is provided with a circuit module, a transformer 2, an electric control switch module 3 and a control panel 4;

[0034] The circuit module includes a main control board 10, and a rectifier inverter circuit 202, a welding control circuit 30 and a cutting control circuit 40 electrically connected to the main control board 10;

[0035] The transformer 2 is provided with a first output connector 21 and a second output connector 22. The first output connector 21 is electrically connected to the welding control circuit 30 via the rectifier inverter circuit 202 and the electronically controlled switch module 3. The second output connector 22 is connected to the cutting control circuit 40 via the electronically controlled switch module 3.

[0036] The chassis 1 is provided with a cutting output interface 1a connected to the output end of the cutting control circuit 40, and a welding output interface 1b connected to the output end of the welding control circuit 30;

[0037] The chassis 1 is provided with a mounting slot 100 for mounting the control panel 4. A push button switch 1c is provided on one side of the mounting slot 100. A pushing component is provided between the control panel 4 and the chassis 1. The push button switch 1c is electrically connected to the pushing component. A universal positioning joint 6 is provided between the driving end of the pushing component and the back of the control panel 4. The pushing component is used to drive the control panel 4 away from or close to the mounting slot 100.

[0038] In this embodiment, the cutting or welding function is selected through the control panel 4. Under the action of the main control board 10, the welding output interface 1b and the cutting output interface 1a are respectively controlled by the electric control switch, which can prevent the high voltage of the cutting output interface 1a from causing electric shock to personnel when using manual welding or gas shielded welding functions, and avoid the short circuit caused by the welding output interface 1b not being disconnected when using the cutting function, thereby realizing safe, stable and reliable switching between welding and cutting functions to meet multi-purpose use.

[0039] In addition, in this embodiment, under normal use, the control panel 4 is placed in the installation groove 100. When the use angle needs to be adjusted, the button switch 1c is first turned on, and the pushing component pushes the control panel 4 in the direction away from the installation groove 100. After moving to the set position, due to the setting of the universal positioning joint 6, the control panel 4 can be manually adjusted to the required angle; conversely, when the button switch 1c is turned off, the push component is reset. The control panel 4 can automatically adjust the angle during the reset process and be completely placed in the installation groove 100, thereby meeting the operator's multi-angle use and improving the convenience of use.

[0040] Further, such as Figure 2 、 3 As shown, in order to achieve pushing and pulling and angle adjustment of the control panel 4; the pushing component includes a linear drive 5 arranged in the chassis 1, one end of the universal positioning joint 6 is connected to the middle of the back of the control panel 4, and the other end passes through the bottom of the mounting slot 100 to the inside of the chassis 1 and is connected to the driving end of the linear drive 5.

[0041] Further, such as Figure 2 As shown, in order to improve the firmness of the control panel 4 when it is placed in the installation groove 100, a magnetic block 7 is provided on the outer surface of the bottom of the installation groove 100 to be magnetically attracted to the back of the control panel 4.

[0042] Further, such as Figure 1 、 2 As shown, the transformer 2 further includes a high-frequency coupling reactor 8 and a high-frequency discharger 9. The transformer 2 also includes a third output connector 23. The high-frequency coupling reactor 8 includes a magnetic core 81 in a rectangular frame structure. A left reactor coil 82, a right reactor coil 83, and a high-frequency coupling coil 84 are wound around the left, right, and lower frame columns of the magnetic core 81, respectively.

[0043] Both ends of the high-frequency coupling coil 84 are connected to the high-frequency discharger 9, one end of the left inductor coil 82 is connected to the first output connector 21, and the other end is connected to one end of the right inductor coil 83, and the other end of the right inductor coil 83 is electrically connected to the input end of the welding output interface 1b through the electronically controlled switch module 3.

[0044] In this embodiment, the high-frequency coupling inductor 8 adopts a structural design in which a coupler and the inductor reuse a pair of magnetic cores 81, which reduces manufacturing costs and reduces the weight of the arc welding machine. Under the action of the main control board 10, the above structure controls the on and off of the coupling output end and the inductance output end of the high-frequency coupling inductor 8 respectively through the electronically controlled switch module 3 according to whether the arc welding machine is in the arc ignition or arc maintenance state. This effectively reduces the energy consumption and electromagnetic interference caused by the current entering the coupled high-frequency coil to generate heat, and can continuously output pulse voltage and pulse current to maintain the continuity of the output voltage and current, thereby achieving low energy consumption and no electromagnetic interference in welding.

[0045] Further, such as Figure 1 、 2 As shown, the electric control switch module 3 includes a first contactor 31 , one end of the first contactor 31 is connected to the input end of the welding control circuit 30 , and the other end is connected to the output end of the rectifier inverter circuit 202 .

[0046] Further, such as Figure 1 As shown, the rectifier-inverter circuit 202 includes a rectifier circuit 201 and an inverter circuit 202 electrically connected in sequence, and the input end of the rectifier circuit 201 is connected to the first output connector 21;

[0047] The electric control switch module 3 includes a second contactor 32 , one end of which is connected to the input end of the welding control circuit 30 , and the connection point of the other end with the rectifier inverter circuit 202 is located between the inverter circuit 202 and the rectifier circuit 201 .

[0048] In this embodiment, the first rectifier circuit 201 is used to convert alternating current into unidirectional pulsating direct current, and the inverter circuit 202 is used to convert unidirectional pulsating direct current into pulsed alternating current. Thus, by controlling the on and off of the first contactor 31 and the second contactor 32, the welding machine can continuously output pulsed alternating current or unidirectional pulsating direct current, thereby meeting more needs of users.

[0049] Further, such as Figure 1 、 2 As shown, in order to realize the control of the on-off of the cutting output interface 1a; the electronically controlled switch module 3 also includes a third contactor 33, one end of the third contactor 33 is connected to the second output connector 22, and the other end is connected to the input end of the seven control circuits; the cutting gun is connected to the welding machine through the cutting output interface 1a.

[0050] Further, such as Figure 1 As shown, in order to realize the on-off control of the reactance output end and the coupling output end and the welding output interface 1b, the electronically controlled switch module 3 also includes a fourth contactor 34, one end of the fourth contactor 34 is connected to the reactance output end, and the other end is connected to the input end of the welding output interface 1b.

[0051] The electric control switch module 3 further includes a fifth contactor 35 , one end of which is connected to the coupling output end of the high-frequency discharger 9 , and the other end of which is connected to the welding control circuit 30 .

[0052] For those skilled in the art, various other corresponding changes and deformations can be made based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of this utility model patent.
