Abstract

This invention discloses a conductive tip processing device and method. It precisely processes used conductive tips that have reached the end of their service life, causing them to deform and changing the original straight aperture to a curved aperture. This increases the contact area and friction between the welding wire and the inner wall of the conductive tip, restricts the oscillation amplitude of the welding wire passing through, restores the conductive tip's conductivity stability and basic function of limiting and constraining the welding wire end, thus meeting the requirements of the welding process. The purpose of this invention is to enable the reuse of used conductive tips, effectively extend their service life, improve the utilization rate of precious non-ferrous metals, and reduce the waste of scarce resources.

Description

Technical Field

[0001] This invention belongs to the field of welding technology, specifically relating to a device and method for processing curved aperture conductive nozzles. Background Technology

[0002] CO2 gas shielded welding is one of the main welding methods currently used. This welding method requires the use of a conductive tip to perform the welding process. The conductive tip is a cylindrical copper structure with a straight hole in the center, such as... Figure 1 As shown, the conductive tip serves a dual purpose: conducting current and constraining the position of the welding wire that passes through it. After a certain period of use, the central aperture of the conductive tip will gradually wear and enlarge, as... Figure 2 and Figure 3 As shown, the conductivity and constraint effect of the welding wire passing through the core gradually decrease, the contact between the welding wire and the contact tip becomes poor, the conductivity weakens, and the welding current becomes unstable. Due to the increased aperture of the contact tip and the stress release effect of the disc welding wire during the wire feeding process, the welding wire swings too much at the outlet position of the contact tip, which eventually makes the contact tip unusable and scrapped.

[0003] Once the orifice of a conductive nozzle wears down to a certain extent, it becomes unusable and must be scrapped. This results in a short service life, high usage volume, high procurement costs, and low utilization rate of precious non-ferrous metals, which to some extent leads to a waste of scarce resources. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a conductive tip processing device and method, which enables the reuse of scrapped conductive tips, effectively extends the service life of conductive tips, improves the utilization rate of precious non-ferrous metals, and reduces the waste of scarce resources.

[0005] The objective of this invention is achieved through the following technical solution: a conductive nozzle processing device, comprising a processing device base, a processing device top plate, a first electro-hydraulic oil top, a second electro-hydraulic oil top, a fixing structure, a connecting rod, an automatic wire clamping and releasing device, and an electrical control system.

[0006] The processing device base is cubic in shape, with a limiting groove on the upper surface that matches the lower surface of the conductive nozzle, and a groove at the center of the limiting groove that matches the lower surface of the conductive nozzle.

[0007] The top plate of the processing device is cubic in shape, and the lower surface has a limiting groove that matches the upper surface of the conductive nozzle. The conductive nozzle can be fixed in the limiting groove inside the base and the top plate of the processing device.

[0008] One end of the conductive tip limiting groove is matched with the smaller end of the conductive tip, and the other end is matched with the diameter of the conductive tip orifice. The welding wire can extend out of the processing device from the conductive tip limiting groove.

[0009] The lateral length of the top plate of the processing device is less than that of the base of the processing device. One end is placed flush with the base of the processing device, and the other end is placed inside the edge of the upper surface of the base of the processing device.

[0010] The top plate of the processing device and the two ends of the base of the processing device are locked by a locking mechanism.

[0011] The top plate of the processing device has an opening, and the first electro-hydraulic jack is fixed to the opening position of the top plate of the processing device through a fixing structure, extending into the opening on the top plate of the processing device.

[0012] The second electro-hydraulic jack is fixed on the base of the processing device with one end of the welding wire extending out. A connecting rod is fixed to the end of the second electro-hydraulic jack, and a thrust gauge is installed on the second electro-hydraulic jack.

[0013] The automatic wire clamping and releasing device is fixed on the connecting rod, and the welding wire can be fixed in the automatic wire clamping and releasing device.

[0014] The electrical control system is electrically connected to the first electro-hydraulic jack, the second electro-hydraulic jack, and the automatic clamping and releasing device for welding wire, and is used to control the operation of the first electro-hydraulic jack, the second electro-hydraulic jack, and the automatic clamping and releasing device for welding wire.

[0015] Preferably, the locking mechanism on the top plate and base of the processing device includes a rotary hinge, a strong magnet, and a strong magnet switch, wherein the rotary hinge is disposed on one side of the top plate and base of the processing device that is flush with the side surface, and the strong magnet and the strong magnet switch are disposed on the other side of the base of the processing device.

[0016] Preferably, the fixing structure of the first electro-hydraulic jack is a clamping plate structure set on both sides of the opening in the top plate of the processing device, and the top of the first electro-hydraulic jack is fixed to the clamping plates on both sides.

[0017] In addition to providing a conductive tip processing apparatus, the present invention further provides a conductive tip processing method, specifically including the following steps:

[0018] Step 1: Setting up the electrical control association for the processing device

[0019] Step 1.1: Open the top plate of the conductive tip processing device and insert a new conductive tip.

[0020] Step 1.2: Lower the top plate of the processing device, tighten the locking mechanism, and securely fix the conductive nozzle in the limiting groove of the conductive nozzle.

[0021] Step 1.3: Pass a section of welding wire through the new contact tip and the automatic wire clamping and releasing device, and use the electronic control system to lock the automatic wire clamping and releasing device.

[0022] Step 1.4: Test the welding wire tension

[0023] The second electro-hydraulic jack is activated. Under the push of the second electro-hydraulic jack, the welding wire is pulled through the contact nozzle at a constant speed. At this time, the thrust gauge records the pulling force of the second electro-hydraulic jack on the welding wire in real time and transmits it to the electro-control system in real time. The pulling force F01 on the welding wire during this process is recorded in real time. The magnitude is equal to the friction force between the welding wire and the contact nozzle. The electro-control system is set up so that it will automatically stop when the pulling force F01 is reached.

[0024] Step 1.5: Set the first and second electro-hydraulic jacks through the electronic control system, start and stop them simultaneously, and automatically reset them after stopping;

[0025] Step 1.6: The automatic clamping and releasing device for the electrical control welding wire releases its clamping on the welding wire, allowing the welding wire to exit from the wire inlet direction;

[0026] Step 1.7: Open the locking mechanism to allow the base of the processing device and the top plate of the processing device to be in a free state. Open the top plate of the conductive nozzle processing device and remove the conductive nozzle.

[0027] Step 2: Processing the worn conductive tip

[0028] Step 2.1: Place the worn conductive tip into the processing device;

[0029] Step 2.2: Cover the top plate of the processing device and lock it with a locking mechanism;

[0030] Step 2.3: Pass a free section of welding wire through the worn contact tip and the automatic clamping and releasing device for the welding wire, and automatically lock it in place using electrical control.

[0031] Step 2.4: Start the electronic control system and operate the first and second electronic hydraulic jacks. While the second electronic hydraulic jack is pulling the welding wire at a constant speed, the first electronic hydraulic jack simultaneously begins to apply downward pressure to the contact nozzle, causing the contact nozzle to deform. The pulling force of the second electronic hydraulic jack continues to increase. When the pulling force reaches the preset F01, the electronic control system automatically controls and stops the operation of the first and second electronic hydraulic jacks. At this time, the first and second electronic hydraulic jacks automatically reset, and the electronic control system automatically operates the welding wire clamping and releasing device to release it, allowing the welding wire to exit from the wire inlet direction.

[0032] Step 2.5: Open the locking mechanism to allow the base of the processing device and the top plate of the processing device to be in a free state;

[0033] Step 2.6: Open the top plate of the conductive tip processing device, take out the conductive tip, and complete the processing of one conductive tip.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] This invention provides a conductive tip processing device and method. It measures and controls the tension of the welding wire by an electro-hydraulic jack, measuring the frictional force as the welding wire passes through a normally functioning conductive tip. Using this frictional force as a standard, the device further modifies the shape of the worn conductive tip's orifice from a straight line to a curve using the electro-hydraulic jack, increasing the frictional force as the welding wire passes through the worn tip and restoring its good conductivity. Furthermore, changing the orifice shape effectively prevents the welding wire from rotating inside the tip, reducing its sway at the tip's exit end, improving the accuracy of the wire's end position, and preventing irregular, large-amplitude swaying, thus meeting welding requirements. This invention uses two electro-hydraulic jacks that operate simultaneously, satisfying post-processing usage requirements while preventing over-processing and excessive deformation of the conductive tip, which could make the welding wire difficult to pass through and render it unusable.

[0036] After being processed by the processing device, conductive tips with different degrees of wear during use experience the same frictional force when the welding wire passes through the conductive tip, resulting in consistent conductivity. The processed conductive tip only deforms in its middle section, while the two ends remain unchanged, ensuring concentricity between the welding wire inlet and outlet ends and preventing excessive swaying at the wire end. The grooved structure of the processing device's base provides sufficient space for the deformation of the conductive tip. Attached Figure Description

Detailed Implementation

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0049] like Figure 4 As shown, the technical solution of the present invention provides a conductive tip processing device including: a processing device base 1, a processing device top plate 2, a first electro-hydraulic oil top 3, a second electro-hydraulic oil top 4, a fixing structure 5, a connecting rod 6, an automatic wire clamping and loosening device 7, and an electrical control system.

[0050] The processing device base 1 is cubic in shape, with a limiting groove on the upper surface that matches the lower surface of the conductive nozzle 8. A groove 9 is formed at the center of the limiting groove that matches the lower surface of the conductive nozzle on the processing device base 1.

[0051] The top plate 2 of the processing device is cubic in shape, and a limiting groove adapted to the upper surface of the conductive nozzle 8 is opened on the lower surface. The conductive nozzle 8 can be fixed in the limiting groove inside the base 1 and the top plate 2 of the processing device.

[0052] One end of the conductive tip limiting groove is matched with the thinner end of the conductive tip 8, and the other end is matched with the diameter of the conductive tip 8. The welding wire can extend out of the processing device from the conductive tip limiting groove.

[0053] The lateral length of the top plate 2 of the processing device is less than that of the base 1 of the processing device. One end is placed flush with the base 1 of the processing device, and the other end is placed inside the edge of the upper surface of the base 1 of the processing device.

[0054] The top plate 2 of the processing device and the base 1 of the processing device are locked at both ends by a locking mechanism.

[0055] The top plate 2 of the processing device has an opening, and the first electro-hydraulic oil top 3 is fixed at the opening position of the top plate 2 of the processing device through the fixing structure 5, extending into the opening on the top plate 2 of the processing device.

[0056] The second electro-hydraulic jack 4 is fixed on the base 1 of the processing device, with one end of the welding wire extending out. A connecting rod 6 is fixed to the end of the second electro-hydraulic jack 4, and a thrust gauge is installed on the second electro-hydraulic jack 4.

[0057] The automatic wire clamping and releasing device 7 is fixed on the connecting rod 6, and the welding wire can be fixed in the automatic wire clamping and releasing device 7.

[0058] The electrical control system is electrically connected to the first electrically controlled hydraulic jack 3, the second electrically controlled hydraulic jack 4, and the automatic wire clamping and releasing device 7, and is used to control the operation of the first electrically controlled hydraulic jack 3, the second electrically controlled hydraulic jack 4, and the automatic wire clamping and releasing device 7.

[0059] like Figures 5 to 6 As shown, in one embodiment of the present invention, the locking mechanism on the top plate 2 and the base 1 of the processing device includes a rotating hinge 10, a strong magnet 11, and a strong magnet switch 12. The rotating hinge 10 is disposed on one side of the top plate 2 and the base 1 of the processing device, which is flush with the side surface. The strong magnet 11 and the strong magnet switch 12 are disposed on the other side of the base 1 of the processing device. The fixing structure 5 of the first electro-hydraulic hydraulic jack 3 is a clamp-type structure disposed on both sides of the opening in the top plate 2 of the processing device. The top of the first electro-hydraulic hydraulic jack 3 is fixed to the clamps on both sides.

[0060] In addition to providing a conductive tip processing device, the present invention further provides a method for processing a conductive tip using the aforementioned conductive tip processing device, specifically including the following steps:

[0061] Step 1: Setting up the electrical control association for the processing device

[0062] Step 1.1: Open the top plate 2 of the conductive nozzle processing device. It is not necessary to open it too much, just enough to insert the conductive nozzle 8. Insert a new conductive nozzle 8.

[0063] Step 1.2: Lower the top plate 2 of the processing device, lock the locking mechanism, and firmly fix the conductive nozzle 8 in the limiting groove of the conductive nozzle;

[0064] Step 1.3: Pass a section of welding wire through the new contact tip 8 and the automatic wire clamping and releasing device 7, and use the electronic control system to lock the automatic wire clamping and releasing device 7;

[0065] Step 1.4: Test the welding wire tension

[0066] The second electro-hydraulic jack 4 is activated. Under the push of the second electro-hydraulic jack 4, the welding wire is pulled through the conductive nozzle 8 at a constant speed. The thrust gauge records the pulling force of the second electro-hydraulic jack 4 on the welding wire in real time and transmits it to the electro-control system in real time. The pulling force F01 on the welding wire during this process is recorded in real time. The magnitude is equal to the friction force between the welding wire and the conductive nozzle 8. The electro-control system is set up so that it will automatically stop when the pulling force F01 is reached.

[0067] Step 1.5: Set the first electro-hydraulic jack 3 and the second electro-hydraulic jack 4 through the electronic control system, start and stop them simultaneously, and automatically reset them after stopping;

[0068] Step 1.6: The automatic clamping and releasing device 7 for electrically controlled welding wire releases its clamping on the welding wire and exits the welding wire from the wire inlet direction;

[0069] Step 1.7: Open the locking mechanism to allow the base 1 of the processing device and the top plate 2 of the processing device to be in a free state. Open the top plate 2 of the conductive nozzle processing device and take out the conductive nozzle 8.

[0070] Step 2: Processing the worn conductive tip

[0071] Step 2.1: Place the worn conductive tip 8 into the processing device;

[0072] Step 2.2: Cover the top plate 2 of the processing device and lock it with a locking mechanism;

[0073] Step 2.3: Pass a free section of welding wire through the worn conductive tip 8 and the automatic wire clamping and releasing device 7, and automatically lock it in place using electrical control.

[0074] Step 2.4: Start the electronic control system and operate the first electronically controlled hydraulic jack 3 and the second electronically controlled hydraulic jack 4. While the second electronically controlled hydraulic jack 4 is pulling the welding wire at a constant speed, the first electronically controlled hydraulic jack 3 simultaneously begins to apply downward pressure to the conductive nozzle 8, causing the conductive nozzle 8 to deform. The pulling force of the second electronically controlled hydraulic jack 4 continues to increase. When the pulling force reaches the preset F01, the electronic control system automatically controls and stops the operation of the first electronically controlled hydraulic jack 3 and the second electronically controlled hydraulic jack 4. At this time, the first electronically controlled hydraulic jack 3 and the second electronically controlled hydraulic jack 4 automatically reset, and the electronically controlled welding wire automatic clamping and releasing device 7 releases it, allowing the welding wire to exit from the welding wire inlet direction.

[0075] Step 2.5: Open the locking mechanism to allow the base 1 of the processing device and the top plate 2 of the processing device to be in a free state;

[0076] Step 2.6: Open the top plate 2 of the conductive nozzle processing device, take out the conductive nozzle 8, and complete the processing of one conductive nozzle 8.

[0077] like Figures 7 to 9As shown, in one embodiment of the present invention, the method for processing a conductive tip using the above-described conductive tip processing device is as follows:

[0078] In this embodiment, the conductive nozzle processing device includes a processing device base 1, a processing device top plate 2, a first electro-hydraulic hydraulic top 3, a second electro-hydraulic hydraulic top 4, an automatic wire clamping and loosening device 7, a connecting rod 6, a rotating hinge 10 between the processing device base 1 and the processing device top plate 2, a fixing structure 5, a strong magnet 11 and a strong magnet switch 12, and a related electrical control system.

[0079] Step 1: Setting up the electrical control association for the processing device

[0080] Step 1.1: Open the top plate 2 of the conductive nozzle processing device. It is not necessary to open it too much, just enough to insert the conductive nozzle 8. Insert a new conductive nozzle 8.

[0081] Step 1.2: Lower the top plate 2 of the processing device, lock the rotating hinge 10 and the magnetic switch 12, and firmly fix the conductive nozzle 8 in the limiting groove of the conductive nozzle;

[0082] Step 1.3: Pass a section of welding wire through the new contact tip 8 and the automatic wire clamping and releasing device 7, and use the electronic control system to lock the automatic wire clamping and releasing device 7;

[0083] Step 1.4: Test the welding wire tension

[0084] The second electro-hydraulic jack 4 is activated. Under the push of the second electro-hydraulic jack 4, the welding wire is pulled through the conductive nozzle 8 at a constant speed. The thrust gauge records the pulling force of the second electro-hydraulic jack 4 on the welding wire in real time and transmits it to the electro-control system in real time. The pulling force F01 on the welding wire during this process is recorded in real time. The magnitude is equal to the friction force between the welding wire and the conductive nozzle 8. The electro-control system is set up so that it will automatically stop when the pulling force F01 is reached.

[0085] Step 1.5: Set the first electro-hydraulic jack 3 and the second electro-hydraulic jack 4 through the electronic control system, start and stop them simultaneously, and automatically reset them after stopping;

[0086] Step 1.6: The automatic clamping and releasing device 7 for electrically controlled welding wire releases its clamping on the welding wire and exits the welding wire from the wire inlet direction;

[0087] Step 1.7: Turn on the strong magnet switch 12 to put the base 1 of the processing device and the top plate 2 of the processing device in a free state. Open the top plate 2 of the conductive nozzle processing device by pulling the handle of the magnet switch 12 upward to open the top plate 2 of the conductive nozzle processing device. It is not necessary to open it too much, just enough to take out the conductive nozzle 8. Take out the conductive nozzle 8 to complete the setting of the processing device and the electrical control connection, and prepare to process the conductive nozzle 8.

[0088] Step 2: Processing the worn conductive tip

[0089] Step 2.1: Place the worn conductive tip 8 into the processing device;

[0090] Step 2.2: Cover the top plate 2 of the processing device and lock it using the rotating hinge 10 and the strong magnet 11;

[0091] Step 2.3: Pass a free section of welding wire through the worn conductive tip 8 and the automatic wire clamping and releasing device 7, and automatically lock it in place using electrical control.

[0092] Step 2.4: Start the electronic control system and operate the first electronically controlled hydraulic jack 3 and the second electronically controlled hydraulic jack 4. While the second electronically controlled hydraulic jack 4 is pulling the welding wire at a constant speed, the first electronically controlled hydraulic jack 3 simultaneously begins to apply downward pressure to the conductive nozzle 8, causing the conductive nozzle 8 to deform. The pulling force of the second electronically controlled hydraulic jack 4 continues to increase. When the pulling force reaches the preset F01, the worn conductive nozzle 8 deforms, and the friction force when the welding wire passes through the core returns to its original value. Its current conduction performance is also fully restored. At the same time, since the diameter of the welding wire changes from a straight line to a curve, it can effectively prevent the welding wire from rotating inside the conductive nozzle 8, thereby reducing its swing amplitude at the outlet end of the conductive nozzle 8. The electronic control system automatically stops the operation of the first electronically controlled hydraulic jack 3 and the second electronically controlled hydraulic jack 4. At this time, the first electronically controlled hydraulic jack 3 and the second electronically controlled hydraulic jack 4 automatically reset, improving the processing efficiency of the conductive tip. The electronically controlled automatic wire clamping and releasing device 7 releases the wire, allowing it to exit from the wire inlet direction. The worn conductive tip 8 is processed as follows: Figure 10 As shown.

[0093] Step 2.5: Turn on the strong magnet switch 12 to put the processing device base 1 and the processing device top plate 2 in a free state;

[0094] Step 2.6: Pull the handle of the magnetic switch 12 upwards to open the top plate 2 of the conductive nozzle processing device, remove the conductive nozzle 8, and complete the processing of one conductive nozzle 8. Repeat steps 1-7 above to complete the processing of the other conductive nozzles 8.

[0095] In this embodiment, the processing device can perform multiple processing operations on a conductive tip that can no longer be used due to the increased aperture during use, thereby significantly extending the service life of the conductive tip.

Step 1.5: Set the first electro-hydraulic jack (3) and the second electro-hydraulic jack (4) through the electronic control system, start and stop them simultaneously, and automatically reset them after stopping; Step 1.6: The electric control of the automatic clamping and releasing device (7) for welding wire releases the clamping of the welding wire and exits the welding wire from the wire inlet direction; Step 1.7: Open the locking mechanism to make the base (1) of the processing device and the top plate (2) of the processing device free, open the top plate (2) of the conductive nozzle processing device, and take out the conductive nozzle (8); Step 2: Processing the worn conductive tip Step 2.1: Place the worn conductive tip (8) into the processing device; Step 2.2: Cover the top plate (2) of the processing device and lock it with a locking mechanism; Step 2.3: Pass a free section of welding wire through the worn conductive tip (8) and the automatic clamping and releasing device (7) of the welding wire, and automatically lock it in place by electrical control; Step 2.4: Start the electronic control system and operate the first electronic hydraulic jack (3) and the second electronic hydraulic jack (4). While the second electronic hydraulic jack (4) is pulling the welding wire at a constant speed, the first electronic hydraulic jack (3) simultaneously applies downward pressure to the conductive nozzle (8), causing the conductive nozzle (8) to deform. The pulling force of the second electronic hydraulic jack (4) continues to increase. When the pulling force reaches the preset F01, the electronic control system automatically controls and stops the operation of the first electronic hydraulic jack (3) and the second electronic hydraulic jack (4). At this time, the first electronic hydraulic jack (3) and the second electronic hydraulic jack (4) automatically reset. The electronic control system operates the welding wire automatic clamping and releasing device (7) to release it and exit the welding wire from the inlet direction. Step 2.5: Open the locking mechanism to allow the base (1) of the processing device and the top plate (2) of the processing device to be in a free state; Step 2.6: Open the top plate (2) of the conductive nozzle processing device, take out the conductive nozzle (8), and complete the processing of one conductive nozzle (8).
