Description

Technical Field

[0001] The present invention relates to the technical field of electric welding machines, in particular to an inverter direct current electric welding machine. Background Art

[0002] Electric welders use a high-temperature arc generated by a momentary short circuit between the positive and negative electrodes to melt the solder on the electrode and the material being welded, thereby bonding the two objects. Their structure is very simple: a high-power transformer. Electric welders are generally divided into two types based on the type of output power: AC and DC. They utilize the principle of inductance, which generates a significant voltage change when the inductor is switched on and off. The high-voltage arc generated by the momentary short circuit between the positive and negative electrodes melts the solder on the electrode, bonding the atoms together.

[0003] When the electric welder is working, both its body and the wires that supply energy to it will generate a lot of heat. Among the two, the use of the electric welder is accompanied by a heat dissipation structure, but the wires do not, which makes it extremely difficult for the wires to dissipate heat, and the accumulation of wires may cause pile combustion. Summary of the Invention

The heat dissipation module includes a bellows installed on the bottom of the mounting plate, a fan connected and communicated with the bellows, two hydraulic cylinders vertically penetrating the bottom of the bellows, and a guard plate connected to the movable end of the hydraulic cylinder. The guard plate slides vertically through the mounting plate and the top of the base, and the guard plate fits the outside of the winding drum.

After the two rubber pads are clamped on the ring sleeve on the top of the winding drum, the distance between the two movable pressure plates is fixed by a threaded rod, and then the external PLC starts the fan and the hydraulic cylinder. After the two hydraulic cylinders lift the guard plate, the guard plate cooperates with the rubber pad to cover the wires, and then the fan injects the generated cold air into the bellows, and then the cold air cools the wires through multiple air holes, thereby improving the heat dissipation effect of the wires and preventing the wires from burning.

[0008] In a preferred example, the present invention can be further configured as follows: multiple air holes are equally spaced and arranged in a ring shape, and the multiple air holes on the mounting plate are vertically coaxial with the multiple air holes on the base and the multiple air holes on the winding drum.

[0010] In a preferred example, the present invention can be further configured as follows: the multiple rollers are arranged in a matrix, and the bottoms of the multiple rollers are all located on the same horizontal plane.

[0011] In a preferred example, the present invention can be further configured as follows: the motor is vertically coaxial with the core of the bobbin, and the welding machine body, motor, three-section electric push rod and fan are all electrically connected to an external PLC.

[0012] In a preferred example, the present invention can be further configured as follows: wire sleeves are installed on both sides of the lifting plate, and the wire sleeves are connected to the interior of the lifting plate.

[0013] In a preferred example, the present invention can be further configured as follows: a reinforcing plate is sleeved on the outer side of the plate body, and the reinforcing plate is connected to the outer wall of the rubber pad.

[0014] In a preferred example, the present invention can be further configured as follows: an annular slide is formed between the winding drum and the ring sleeve, and the sleeve plate is adapted to the annular slide.

[0015] In a preferred example, the present invention can be further configured as follows: two hydraulic cylinders are connected in series, and the hydraulic cylinders are electrically connected to an external PLC.

[0016] In a preferred example, the present invention can be further configured as follows: the guard plate is slidably connected between the two rubber pads, and the two guard plates and the two rubber pads are staggered and arranged in a ring shape.

[0017] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0018] 1. In the present invention, the movable pressing plate indirectly moves the plate body and the rubber pad. After the two rubber pads are clamped on the ring sleeve on the top of the winding drum, the distance between the two movable pressing plates is fixed by a threaded rod. Then the external PLC starts the fan and the hydraulic cylinder. After the two hydraulic cylinders lift the guard plate, the guard plate cooperates with the rubber pad to cover the wires. Then the fan injects the generated cold air into the bellows, and then the cold air cools the wires through multiple air holes, thereby improving the heat dissipation effect of the wires and preventing the wires from burning.

[0019] 2. In the present invention, the mounting plate is pushed, and after the welding machine body is moved to the working position, the wires on the welding machine body are extended, and then the wires are connected to the external power supply to ensure that the welding machine body can work smoothly. The structure is simple and easy to use.

[0020] 3. In the present invention, when winding the wire, the external PLC starts the motor and the three-section electric push rod. The motor rotates the sleeve plate, the three-section electric push rod and the lifting plate through the Y-shaped connecting frame. Then the three-section electric push rod drives the lifting plate to move back and forth, and then the wire is evenly wound on the outside of the winding drum, and the winding effect is good.

[0037] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0038] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0039] An inverter DC welding machine provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example

[0040] Combine Figures 1-9 As shown, the present invention provides an inverter DC welding machine, including a welding module 100, a winding module 200, a reinforcement module 300 and a heat dissipation module 400, wherein the welding module 100 includes a mounting plate 110, two pads 120 connected to the bottom of the mounting plate 110, two rollers 130 movably mounted on the bottom of the pad 120, a welding machine body 140 mounted on the top of the mounting plate 110, a base 150 connected to the top of the mounting plate 110, and a winding drum 160 connected to the top of the base 150, wherein the mounting plate 110, the base 150 and the winding drum 160 are all provided with a plurality of ventilation holes;

[0041] The winding module 200 includes a motor 230 mounted on the top of the winding drum 160, a Y-shaped connecting frame 240 connected to the output shaft of the motor 230, a sleeve 250 connected to the bottom end of the Y-shaped connecting frame 240, a three-section electric push rod 260 connected to the sleeve 250, and a lifting plate 270 connected to the movable end of the three-section electric push rod 260. The lifting plate 270 is slidably arranged inside the sleeve 250.

[0042] The reinforcement module 300 includes two movable pressure plates 310 movably mounted on the top of the mounting plate 110, a plurality of L-shaped plates 320 mounted on the inner side of the movable pressure plates 310, a plate body 330 connected between the plurality of L-shaped plates 320, a rubber pad 340 mounted on the inner side of the plate body 330, a ring 350 movably sleeved on the top of the winding drum 160 and disposed between the two rubber pads 340, a U-shaped plate 360 sleeved on the top of the movable pressure plates 310, and a threaded rod 370 threadedly connected between the two U-shaped plates 360.

[0043] The heat dissipation module 400 includes a bellows 410 installed at the bottom of the mounting plate 110, a fan 420 connected to and communicated with the bellows 410, two hydraulic cylinders 430 vertically passing through the bottom of the bellows 410, and a guard plate 440 connected to the movable end of the hydraulic cylinder 430. The guard plate 440 slides vertically through the mounting plate 110 and the top of the base 150, and the guard plate 440 is attached to the outside of the winding drum 160.

[0044] Furthermore, multiple air holes are equally spaced and arranged in a ring shape. The multiple air holes on the mounting plate 110 are vertically coaxial with the multiple air holes on the base 150 and the multiple air holes on the winding drum 160. The air holes are provided to create conditions for the fan 420 to cool the wires.

[0045] Furthermore, the two pads 120 are symmetrical about the vertical center plane of the mounting plate 110, and the thickness of the pads 120 is greater than the thickness of the mounting plate 110. With this size design, the two pads 120 can cooperate to raise the mounting plate 110 to a suitable height, ensuring that the bellows 410 and the fan 420 can be installed smoothly.

[0046] Furthermore, the plurality of rollers 130 are arranged in a matrix, and the bottoms of the plurality of rollers 130 are all located on the same horizontal plane. This layout design ensures that the mounting plate 110 can move smoothly.

[0047] Furthermore, a reinforcing plate 600 is sleeved on the outer side of the plate body 330, and the reinforcing plate 600 is connected to the outer wall of the rubber pad 340. The provision of the reinforcing plate 600 can increase the connection strength between the plate body 330 and the rubber pad 340, thereby increasing the stability of the structure of the device.

[0048] Furthermore, an annular slide is formed between the winding drum 160 and the ring sleeve 350, and the sleeve 250 is adapted to the annular slide. The provision of a shape-changing slide can limit the sleeve 250, making the sleeve 250 rotate more stably.

[0049] Furthermore, the guard plate 440 is slidably connected between the two rubber pads 340, and the two guard plates 440 and the two rubber pads 340 are staggered and arranged in a ring shape. With this layout design, the guard plate 440 cooperates with the rubber pads 340 to seal the space where the wires are located, ensuring that the cold air effectively cools the wires. Example

[0050] Combine Figures 1-9 As shown, based on the first embodiment, the motor 230 is vertically coaxial with the core of the winding reel 160, and the welding machine body 140, the motor 230, the three-section electric push rod 260 and the fan 420 are all electrically connected to the external PLC. This structural design makes the device more intelligent to use.

[0051] Specifically, the two hydraulic cylinders 430 are connected in series, and the hydraulic cylinders 430 are electrically connected to an external PLC. With this structural design, the control of the two hydraulic cylinders 430 will be more convenient, and the user comfort will be improved. Example

[0052] Combine Figure 4-Figure 5As shown, in the above embodiment, wire sleeves 500 are installed on both sides of the lifting plate 270. The wire sleeves 500 are connected to the interior of the lifting plate 270. The wire sleeves 500 can scrape off dust on the outside of the wires to prevent the wires from being damaged by dirt.

[0053] The working principle and use process of the present invention are as follows: in the initial state, the movable pressing plate 310 indirectly moves the plate body 330 and the rubber pad 340. After the two rubber pads 340 clamp the ring 350 on the top of the winding drum 160, the threaded rod 370 is used to fix the distance between the two movable pressing plates 310. Then, when the device is put into actual use, the mounting plate 110 is pushed. After the welding machine body 140 moves to the working position, the wires on the welding machine body 140 are extended, and then the wires are connected to the external power supply to ensure that the welding machine body 140 can work smoothly. Then, when the wires are reeled in, the external PLC starts the motor 230 and the three-section electric push rod. 260, the motor 230 rotates the sleeve plate 250, the three-section electric push rod 260 and the lifting plate 270 through the Y-shaped connecting frame 240, and then the three-section electric push rod 260 brings the lifting plate 270 up and down, and then the wire is evenly wound on the outside of the winding drum 160. Then, after the winding operation is completed, the external PLC starts the fan 420 and the hydraulic cylinder 430. After the two hydraulic cylinders 430 lift the guard plate 440, the guard plate 440 cooperates with the rubber pad 340 to cover the wire, and then the fan 420 injects the generated cold air into the bellows 410, and then the cold air cools the wire through multiple air holes, thereby improving the heat dissipation effect of the wire and preventing the wire from burning.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and alterations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
