Description

Technical Field

[0001] This invention relates to the field of welding, and more specifically to an automatic electrode pressing device. Background Technology

[0002] Welding electrodes consist of a core and a coating. The coating is applied evenly and concentrically onto the core to obtain the electrode. In the actual manufacturing process, the coating is usually applied manually to the core and then pressed. However, manual application can easily result in uneven coating and low processing efficiency.

[0003] An existing patent (CN111318412A) describes a device for pressing flux coating onto welding electrodes. The device involves a rotating brush head that picks up the flux solution, then rotates to contact the electrode surface for application. A threaded block moves the pressing block towards the electrode surface for pressing. However, the brush head cannot ensure uniform application of the flux coating to the electrode core, and flux coating is prone to peeling off during application, affecting electrode quality. Furthermore, the threaded block's movement of the pressing block towards the electrode can cause uneven pressure, resulting in uneven flux coating thickness. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic electrode pressing device that can quickly and evenly apply flux coating to the electrode core without eccentricity.

[0005] This objective is achieved using the following technical solution: a fixing component for securing the welding core, a dispensing component, a storage chamber, and a pressing component that are detachably connected in sequence. The dispensing component has a dispensing groove with an inner diameter equal to the diameter of the welding core after flux coating, i.e., the diameter of the welding electrode. A hollow connecting tube for connecting the welding core is provided within the storage chamber. A first through-slot is provided on the pressing component for the hollow connecting tube to pass through. The dispensing groove, the hollow connecting tube, and the first through-slot are sequentially connected and coaxial. The hollow connecting tube fixes the position of the welding core, ensuring it remains coaxial with the dispensing groove within the dispensing component, storage chamber, and pressing component. This ensures uniform flux coating during flux application, prevents core eccentricity, and improves electrode quality.

[0006] One end of the hollow connecting tube can pass through the pressure piece, so the hollow connecting tube can keep the welding core in a straight line within the length of the hollow connecting tube. When applying the coating, it can further avoid eccentricity and thus ensure uniform coating.

[0007] Meanwhile, the pressing component includes a first moving mechanism and an extrusion plate. The first moving mechanism is used to drive the extrusion plate to move toward the inside of the storage cavity. When the flux coating is applied to the welding core, the extrusion plate continuously extrudes the flux coating in the storage cavity, keeping the flux coating in the storage cavity in a tight state, thereby ensuring that the flux coating applied to the welding core is uniform.

[0008] Furthermore, the fixing component is equipped with a second moving mechanism for moving the discharge component, storage chamber, and pressing component on the welding core. Secondly, the storage chamber is hollow, with the upper end of the hollow connecting pipe connected to the upper end of the storage chamber via a connecting rod, and the interior of the storage chamber communicates with the discharge trough. When the extrusion plate extrudes the coating in the storage chamber, the connecting rod, located at the upper end of the storage chamber, does not affect the extrusion plate's extrusion of the coating, further improving the coating's compaction effect.

[0009] During the preparation process, there is no need to manually move the discharge part, storage chamber and pressing part. Under the uniform action of the second moving mechanism, the coating can be evenly squeezed onto the welding core, thus improving the quality of the welding rod.

[0010] When using this device, first connect the discharge component to the storage chamber, then place the flux coating in the storage chamber to fill the discharge trough and storage chamber. Insert the welding core into the hollow connecting pipe, with one end of the welding core flush with the discharge trough of the discharge component. Then fix one end of the discharge component and the other end of the welding core to the fixing component. The second moving mechanism is connected to the pressing component. The second moving mechanism drives the discharge component, storage chamber and pressing component to move along the straight line where the welding core is located. During the movement, the flux coating is squeezed by the extrusion plate to make the flux coating evenly and densely coated on the welding core.

[0011] Compared with existing devices, this device uses a second moving mechanism to make the discharge component, storage chamber and pressing component move at a constant speed on the welding core. Compared with the structure of manual extrusion coating, this device can initially ensure that the coating is uniformly coated on the welding core. Secondly, during the movement of the welding core, the extrusion plate continuously extrudes the coating in the storage chamber, keeping the coating tightly in the discharge groove, thereby ensuring that when the welding core is extruded from the discharge groove, the coating is uniformly and densely coated on the welding core.

[0012] Secondly, while existing devices use rollers to apply the coating, this device uses a hollow connecting tube of a certain length to position the welding core, ensuring it remains centered during coating and preventing eccentricity. Furthermore, this device uses a discharge trough in the discharge part to press the coating to a uniform thickness, and it is easy to operate. Compared to existing structures, it does not require precise positioning and is more suitable for long-term use.

[0013] Furthermore, after the coated welding core is extruded from the discharge part, the coating on the surface of the welding core is prone to fall off during the subsequent continuous movement, resulting in uneven coating. Therefore, based on the above structure, this device is equipped with a pressing part, which is detachably connected to the upper end of the discharge part. When the coated welding core is extruded from the upper end of the discharge part, it can enter the pressing part for further fixation, promoting better bonding between the coating and the welding core and preventing it from falling off. The pressing component includes several sector plates and an adjusting component. The sector plates form a structure with a hollow circle at the center. The adjusting component is used to adjust the inner diameter of the hollow circle formed by the sector plates. After the discharge component is connected to the pressing component, the hollow circle is connected to the discharge trough and is coaxial. The welding core coated with flux is squeezed out from the discharge component and moves into the hollow circle. The inner diameter of the hollow circle is the same as the outer diameter of the welding core coated with flux, that is, the outer diameter of the welding rod is the same. When the welding rod is in the hollow circle, the front end of the sector plates is in contact with the welding rod, thereby shaping the welding rod and keeping it in the state of flux coating, improving the bonding efficiency between the flux coating and the welding core.

[0014] During use, different thicknesses of coating are usually required. Therefore, the inner diameter of the discharge trough in the discharge part can be changed as needed. The inner diameter of the hollow circle is the same as that of the discharge trough. In order to be suitable for different inner diameters, the adjusting part of this device can adjust the position of the sector plate, thereby adjusting the inner diameter of the hollow circle to make it suitable for different welding rods. The adjusting component can have various structures, as long as it can adjust the position of the sector plates to form hollow circles with different inner diameters. To further simplify operation, the adjusting component of this device includes a first rotating ring, several sector plates are evenly arranged radially on a first fixed ring, several third gears are arranged inside the first fixed ring, and several fourth gears corresponding to the third gears are arranged inside the first rotating ring. The corresponding third and fourth gears are connected by a first rotating rod. Each sector plate is provided with a second gear plate, which meshes with the third gear. The rotation of the first rotating ring drives the fourth gear to rotate, and the fourth gear drives the third gear to rotate through the first rotating rod. The rotation of the third gear drives the second gear plate to move radially on the first fixed ring, thereby adjusting the inner diameter of the hollow circle formed by the several sector plates during the movement, so that the inner diameter of the hollow circle is the same as the inner diameter of the discharge trough.

[0015] The thickness of the fan-shaped plate is greater than 5cm. Therefore, after the welding core is extruded, it can remain compressed for at least 5cm, preventing the coating from falling off and further improving the quality of the welding electrode.

[0016] Furthermore, the fixing component of this device for securing the welding core can secure multiple welding cores simultaneously or only one welding core. The fixing component includes a first connecting plate, a second connecting plate, and a base plate. The first and second connecting plates are connected to the base plate. Both ends of the welding core are connected to the first and second connecting plates, respectively. A second moving mechanism is mounted on the base plate. The second moving mechanism drives the pressure component to move on the welding core, thereby applying the flux coating to the welding core during the movement.

[0017] When multiple welding cores are fixed simultaneously and multiple welding rods are prepared simultaneously, the base plate of this device is circular, and several grooves are arranged radially on the base plate. One end of the groove passes through the side of the base plate, and a first gear plate is arranged on the groove. The first gear plate can slide along the direction of the groove. The first gear plate is detachably connected to the pressing component. The sliding of the first gear plate along the groove drives the pressing component to move along the straight line of the hollow connecting tube. There are various structures for driving the first gear plate to move. In this structure, the preferred one is that a first gear is connected to the first gear plate, and a rotating ring is arranged on the base plate. Several second gears corresponding one-to-one with the first gear are arranged on the rotating ring. The first gear and the second gear are connected by a second rotating rod. When the rotating ring rotates, the rotating ring drives the second gear to rotate circumferentially. The second gear drives the first gear to rotate through the second rotating rod. The first gear acts on the first gear plate, causing the first gear plate to slide along the groove. When the first gear plate slides along the groove, it drives the pressing component to move along the straight line of the welding core.

[0018] The base plate can be placed horizontally or vertically on the ground, and can be adjusted according to actual needs.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] This invention discloses an automatic electrode pressing device. This device can simultaneously prepare one or more electrode materials and is simple to operate. The device is detachably connected by a discharge component, a storage chamber, and a pressing component, which allows for convenient cleaning of the discharge component, storage chamber, and pressing component for future use. Furthermore, for electrode materials requiring different coating thicknesses, this device can quickly change the discharge component to select a discharge groove with a different inner diameter, thus making it suitable for different sizes.

[0021] Meanwhile, one end of the hollow connecting pipe is in contact with and connected to the discharge trough, and the other end of the hollow connecting pipe passes through the pressure component. Therefore, when the flux coating is applied, the hollow connecting pipe can position the welding core, so that the flux coating is evenly applied to the welding core.

[0022] Secondly, during the movement of the pressing component, the extrusion plate moves towards the inside of the storage cavity, and in the process of moving, it simultaneously extrudes the flux coating, so that the flux coating in the discharge trough is evenly and densely coated on the welding core.

[0023] Furthermore, when preparing multiple welding electrodes simultaneously, this device can simultaneously extrude welding cores, enabling synchronous preparation, which is highly efficient and has a simple structure. Attached Figure Description

[0043] Example 1

[0044] like Figure 1 As shown, it includes a discharge component 1, a storage chamber 3, and a pressing component 7 that are detachably connected in sequence. The structure of the discharge component 1 is as follows: Figure 2 As shown, the discharge component 1 is provided with a discharge trough 2; the structure of the storage chamber 3 is as follows: Figure 3 As shown, a hollow connecting pipe 4 for connecting the welding core is provided inside the material storage chamber 3. One end of the material storage chamber 3 is connected to the discharge part as shown in the figure. Figure 4 As shown, the storage chamber 3 is hollow inside, and the upper end of the hollow connecting pipe 4 is connected to the upper end of the storage chamber 3 via a connecting rod 5. The interior of the storage chamber 3 is also connected to the discharge trough 2. The structure of the pressing component 7 is as follows: Figure 5 As shown, the pressing component 7 is provided with a first through groove 10 for the hollow connecting pipe 4 to pass through. The pressing component 7 is also provided with a pressing block 6. A first moving mechanism 9 is provided between the pressing block 6 and the extrusion plate 8. When the pressing component is connected to the storage cavity, the pressing block compacts the medicated coating in the storage cavity and distributes it evenly in the discharging component and the storage cavity. The first moving mechanism 9 is used to drive the extrusion plate 8 to move towards the interior of the storage cavity 3. Figure 6As shown; the discharge trough 2, the hollow connecting pipe 4, and the first through groove 10 are connected in sequence and coaxial; the fixing part is provided with a second moving mechanism for driving the discharge part 1, the storage cavity 3 and the pressing part 7 to move on the welding core.

[0045] In use, first connect the discharge component 1 and the storage chamber 3. The hollow connecting pipe 4 is in contact with and connected to the discharge trough 2. Place the flux residue into the storage chamber 3, connect the storage chamber 3 and the pressing component 7, so that the pressing block 6 compacts the flux residue in the storage chamber 3 and allows it to flow out of the discharge trough 2. Then, insert one end of the welding core into the hollow connecting pipe 4 and the discharge trough, aligning one end of the welding core with the opening end of the discharge trough 2. Then, fix both ends of the welding core to the fixing component. Initially, the end of the discharge component 1 aligned with the welding core is fixed to the... On the fixing component, the pressing component 7 is connected to the second moving mechanism on the fixing component. The second moving mechanism drives the discharging component 1, the storage cavity 3 and the pressing component 7 to move along the straight line where the welding core is located on the welding core. After the welding core passes through the discharging component 1, the storage cavity 3 and the pressing component 7, the welding core is evenly coated with flux. During the movement of the discharging component 1, the storage cavity 3 and the pressing component 7, the first moving mechanism 9 in the pressing component drives the extrusion plate 8 to move toward the inside of the storage cavity 3, so that the extrusion plate extrudes the flux in the storage cavity, making the flux in the storage cavity uniform and dense.

[0046] Example 2

[0047] Based on the above embodiments, in some embodiments, the first moving mechanism 9 is a spring rod disposed between the pressing member 7 and the extrusion plate 8. When the extrusion plate 8 is located at the upper end of the storage cavity 3, the spring rod is in a compressed state.

[0048] In some embodiments, the first moving mechanism 9 is an adjusting rod with one end connected to the extrusion plate 8 and the other end located outside the pressing member 7, and the hollow connecting tube 4 is located inside the adjusting rod. The adjusting rod includes a first spring segment and a second spring segment. The elastic coefficient of the first spring segment is greater than the spring coefficient of the second spring segment. In use, the other end of the adjusting rod located outside the pressing member 7 is in contact with the fixing member. When the discharge member 1, the storage cavity 3 and the pressing member 7 move, the adjusting rod is compressed and shortened. The second spring segment is located outside the pressing member and is compressed first. The extrusion plate 8 presses the medicine skin in the storage cavity to make the medicine skin in the storage cavity uniform.

[0049] In some embodiments, the first moving mechanism 9 is a telescopic rod disposed between the pressing component 7 and the extrusion plate 8. The extension and retraction speed of the telescopic rod is matched with the moving speed of the second moving mechanism. The specific speed can be adjusted according to actual use. When the second moving mechanism drives the discharge component 1, the storage cavity 3 and the pressing component 7 to move, the telescopic rod drives the extrusion plate to move simultaneously, so that the extrusion plate extrudes the medicine skin and keeps it in a compacted state, that is, the discharge trough 2 is evenly filled with medicine skin.

[0050] Example 3

[0051] Based on the above embodiments, the fixing component includes a first connecting plate 13, a second connecting plate 15, and a base plate 14. The first connecting plate 13 and the second connecting plate 15 are connected to the base plate 14. The first connecting plate 13 and the second connecting plate 15 are each provided with a placement groove. The two ends of the welding core are respectively connected to the two placement grooves. When placing, the two ends of the welding core are directly placed in the placement groove from top to bottom. The second moving mechanism is provided on the base plate 14.

[0052] In some embodiments, such as Figure 7 As shown, the second moving mechanism includes a connecting block 11 detachably connected to the pressing component 7. A first rotating rod 12 is threaded onto the connecting block 11. The first rotating rod 12 is parallel to the hollow connecting tube 4. The rotation of the first rotating rod 12 drives the connecting block 11, the discharge component 1, the storage chamber 3, and the pressing component 7 to move along the straight line of the hollow connecting tube 4. The connecting block and the pressing component 7 are connected by a slot and a snap-fit. Two connecting blocks are connected to the pressing component. Under the action of the rotation of the first rotating rod, the connecting blocks do not rotate with the first rotating rod. Therefore, when the first rotating rod rotates, the connecting blocks can drive the pressing component to move along the straight line of the hollow connecting tube 4. Preferably, during this process, the lower ends of the pressing component 7 and the two connecting blocks are located on the same plane, so that the pressing component maintains a straight line movement during movement.

[0053] In some embodiments, the second moving mechanism includes a connecting block 11 detachably connected to the pressing component 7. A telescopic rod is connected to the connecting block 11. The telescopic rod is parallel to the hollow connecting pipe 4. The telescopic rod extends and retracts, causing the connecting block 11, the discharge component 1, the storage chamber 3, and the pressing component 7 to move along the straight line of the hollow connecting pipe 4.

[0054] Example 4

[0055] Based on the above embodiments, such as Figure 8 As shown, the base plate 14 is circular, and four radial grooves 18 are provided on the base plate 14. One end of each groove 18 passes through the outer side of the base plate 14. A first gear plate 19 is provided on each groove 18, and the first gear plate 19 can slide along the direction of the groove 18. The first gear plate 19 is detachably connected to the pressing component 7. The sliding of the first gear plate 19 along the groove drives the pressing component 7 to move along the straight line of the hollow connecting pipe 4. There are many structures that allow the first gear plate to move within the groove; it can be achieved through a telescopic rod or by rotating a gear.

[0056] In some embodiments, such as Figure 8As shown, a first gear 20 is connected to a first gear plate 19. The rotation of the first gear plate can drive the first gear plate to move on the slide groove. However, in this structure, if there are multiple first gear plates, multiple motors are needed to control the rotation of multiple first gears at the same time. However, this structure is complex and costly. The inventor has designed a structure that can make multiple first gear plates rotate at the same time, including a rotating ring 16 set on the base plate. The rotating ring 16 is provided with a plurality of second gears 17 corresponding one-to-one with the first gear 20. The first gear 20 and the second gears 17 are connected by a second rotating rod 21. The rotating ring 16 rotates, causing the first gear plate 19 to slide along the slide groove.

[0057] In the original state, such as Figure 9 As shown, one end of the discharge component 1 contacts the first connecting plate 13, and the other end of the welding core contacts the second connecting plate. The rotating ring 16 rotates, causing the second gear 17, which meshes with the inner ring of the rotating ring 16, to rotate. The second gear drives the first gear to rotate via the second rotating rod. During the rotation of the first gear, the first gear plate moves, which in turn causes the pressing component 7 to move along the straight line of the hollow connecting pipe 4. The flux coating is applied to the welding core. After coating, as shown... Figure 10 As shown, the position of the first gear plate 19 on the base plate is as follows: Figure 11 As shown.

[0058] In some embodiments, one of the plurality of second gears 17 is an active second gear, which is connected to a motor. The motor drives the active second gear to rotate, and the rotation of the active second gear drives the rotating ring to rotate, which in turn drives the other second gears 17 to rotate.

[0059] In some embodiments, the base plate can be placed directly on the ground, and the four first gear plates 19 are located on the same horizontal plane.

[0060] In some embodiments, a support member is provided on the base plate 14, which positions the base plate 14 on a vertical plane. The first gear plate is located on the same vertical plane and does not contact the ground. Figure 12 As shown.

[0061] Furthermore, the support member is provided with a storage groove, and the base plate 14 is connected to the storage groove. The base plate 14 can slide along a vertical plane within the storage groove. When not in use, the base plate 14 slides in the storage groove, causing the second connecting plate to be positioned within the storage groove. When in use, the base plate 14 slides upward within the storage groove, so that the upper semicircular portions of the base plate 14 and the second connecting plate are outside the storage groove. This facilitates storage when not in use. In this embodiment, the sliding of the base plate along a vertical plane within the storage groove can be achieved through various structures, such as the telescopic movement of a telescopic rod, as long as it can slide along a vertical plane within the storage groove and maintain both the storage position and the position in use.

[0062] Example 5

[0063] Based on the above embodiment, a pressing component is detachably connected to the upper end of the discharge component 1, such as... Figure 13 As shown, the pressing component includes several sector plates 24 and an adjusting component. The several sector plates 24 form a structure with a hollow circle at the center. The adjusting component is used to adjust the inner diameter of the hollow circle formed by the several sector plates 24. After the discharge component 1 is connected to the pressing component, the hollow circle is connected to the discharge trough 2 and is coaxial.

[0064] After the discharge part 1 is connected to the pressing part, the hollow circle is connected to the discharge groove 2 and is coaxial. The welding core coated with flux is extruded from the discharge part and moves into the hollow circle. The inner diameter of the hollow circle is the same as the outer diameter of the welding core coated with flux, that is, the outer diameter of the welding rod is the same. When the welding rod is in the hollow circle, the front end of the sector plate is in contact with the welding rod, thereby shaping the welding rod and keeping it in the state of flux coating, improving the bonding efficiency between the flux coating and the welding core. The thickness of the sector plate 24 is greater than 5cm. Therefore, after the welding core is extruded, it can be kept pressed for at least 5cm, preventing the flux coating from falling off, further improving the quality of the welding rod.

[0065] During use, the adjusting component can have various structures, as long as it can adjust the position of the sector plates to form hollow circles with different inner diameters. To further simplify operation, the adjusting component of this device includes a first rotating ring 23, several sector plates are evenly arranged radially on a first fixed ring, several third gears are arranged inside the first fixed ring, and several fourth gears 22 corresponding to the third gears are arranged inside the first rotating ring 23. The corresponding third gears and fourth gears 22 are connected by a first rotating rod. Each sector plate 24 is provided with a second gear plate 25, which meshes with the third gear. The rotation of the first rotating ring 23 drives the fourth gear to rotate, and the fourth gear drives the third gear to rotate through the first rotating rod. The rotation of the third gear drives the second gear plate to move radially on the first fixed ring, thereby adjusting the inner diameter of the hollow circle formed by the several sector plates 24 during the movement, so that the inner diameter of the hollow circle is the same as the inner diameter of the discharge trough 2. After the inner diameter of the hollow circle is adjusted, its structure is as follows. Figure 14 As shown. The hollow circle is formed by several sector plates at one end near the center of the first fixed ring. The inner diameter of the hollow circle is adjusted by moving the sector plates radially along the first fixed ring. When the sector plates move radially away from the center of the first fixed ring, the inner diameter of the hollow circle increases; when the sector plates move radially closer to the center of the first fixed ring, the inner diameter of the hollow circle decreases.
