Description

Technical Field

[0001] This utility model relates to the technical field of welding wire storage devices, and specifically to a wire feeding cap for a decagonal welding wire hopper. Background Technology

[0002] Metal welding is the process of joining two metal components together using flux. Welding wire is a welding material used as filler metal or as a conductor. For ease of storage and use, welding wire is typically coiled and wound in a wire hopper. The wire is fed from the hopper, continuously supplying welding robots or automated equipment. To facilitate wire drawing, a wire feed cap is installed on the hopper, and a locking structure or assembly for securing the cap is located on the hopper wall. However, nowadays, for easier transport and storage, wire hoppers are often made of cardboard stacked into polygonal shapes. The hopper is assembled only before filling with welding wire, making it impossible to install the assembly for securing the wire feed cap on the hopper wall. Furthermore, the welding wire inside the hopper is temporarily in a loose state. If the wire is drawn directly, it often bends or knots, and the coiled wire may even rub against each other when it unwinds, causing flux to fall off, thus affecting the normal use of the welding wire and the quality of the weld. Utility Model Content

[0003] The purpose of this invention is to provide a wire feeding cap for a decagonal welding wire hopper. This wire feeding cap can be quickly and easily installed and fixed on the welding wire hopper, reducing wear or tangling of the welding wire during use and making it more convenient to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wire feed cap for a decagonal welding wire hopper includes a dust cover and a fixing part. The dust cover is a truncated cone shape, smaller at the top and larger at the bottom. A discharge port is provided on the upper end face of the dust cover, and the lower end face of the dust cover extends horizontally outward to form a limiting edge. The fixing part is a polygonal annular structure. A through hole and a retaining edge that mates with the limiting edge are provided on the upper end face of the fixing part. The dust cover passes through the through hole, and the limiting edge is engaged with the lower side of the retaining edge. The inner diameter of the fixing part matches the outer diameter of the welding wire hopper, and the fixing part is fitted onto the opening of the welding wire hopper. The fixing part is formed by stacking retaining plates. The through hole is located in the middle of the retaining plates. Side plates and retaining plates are spaced around the through hole. The side plates and retaining plates are bent to one side to form the side wall of the fixing part.

[0006] Preferably, side plates and snap-fit ​​plates are provided at intervals around the through hole, with five side plates and five snap-fit ​​plates each. A snap-fit ​​protrusion is provided on the side of the snap-fit ​​plate away from the through hole, and a snap-fit ​​opening that mates with the snap-fit ​​protrusion is provided on the edge of the through hole near the snap-fit ​​plate. The side plates and snap-fit ​​plates are bent downward to form the side wall of the fixing part, and the snap-fit ​​plate is bent upward and the snap-fit ​​protrusion engages with the snap-fit ​​opening to fix the side plate.

[0007] Preferably, the height of the fixing part is 72-78mm, and the height of the dust cover is 290-300mm.

[0008] Preferably, an observation window is provided on the side wall of the dust cover, and the observation window is provided with a protective plate made of transparent material.

[0009] Preferably, mounting holes are provided around the discharge port, and the wire feeding tube of the external welding equipment is connected to the discharge port through a connector, which is fixed in the mounting holes by bolts.

[0010] Further preferably, the welding wire drum is a decagonal columnar drum made of cardboard stacked together.

[0011] The beneficial effects of this utility model compared to existing technologies are as follows:

[0012] The wire feed cap includes a dust cover and a fixing part. The inner diameter of the fixing part matches the outer diameter of the wire hopper, and the fixing part is fitted over the opening of the wire hopper. At this time, the edge of the dust cover is secured between the wire hopper and the fixing part. The welding wire coiled inside the wire hopper has outward tension, which tends to compress the wire hopper and cause it to deform outward. Fitting the fixing part over the edge of the wire hopper prevents excessive deformation and increases the friction between the wire hopper and the fixing part through the outwardly expanding sidewall of the wire hopper, ensuring the fixing part is firmly installed and fixed to the wire hopper, thus preventing the wire feed cap from falling off during wire feeding. A wire feeding tube of the welding equipment is connected to the outlet. The welding wire rises from inside the wire hopper and exits from the outlet. As the welding wire gradually rises, if the coiled wire becomes loose, it will move closer to the inside of the dust cover. The conical dust cover causes the loose wire to gradually separate from top to bottom, preventing friction between the wires. Furthermore, the edge of the dust cover is smaller than the inner diameter of the welding wire hopper, which limits the welding wire. The loose welding wire is hindered by the limiting edge and / or the clamping edge during the upward process, so that the adjacent coiled welding wires are separated and gradually enter the dust cover. This further prevents the welding wires from rubbing against each other and causing the welding flux to fall off, thereby preventing the welding wire from bending or knotting.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 5 As shown, a wire feeder cap for a decagonal welding wire hopper is used to be installed on the decagonal welding wire hopper to guide the welding wire out and to seal the welding wire hopper to prevent the welding wire inside the hopper from getting damp or contaminated. The welding wire hopper 8 is a decagonal columnar hopper made of cardboard. The wire feeder includes a dust cover 1 and a fixing part 2. The dust cover 1 is a truncated cone shape with a smaller top and a larger bottom. A discharge port 4 is provided on the upper end face 3 of the dust cover. The lower end face of the dust cover 1 extends horizontally outward to form a limiting edge 5. The fixing part 2 is a polygonal ring structure. A through hole 6 is provided on the upper end face of the fixing part 2. The edge of the through hole forms a retaining edge 7 that cooperates with the limiting edge 5. The dust cover 1 passes through the through hole 6 and the limiting edge 5 is engaged with the lower side of the retaining edge 7. The inner diameter of the fixing part 2 is matched with the outer diameter of the welding wire hopper 8 and the fixing part 2 is sleeved at the opening of the welding wire hopper 8. At this time, the limiting edge 5 is engaged between the upper edge of the welding wire hopper 8 and the retaining edge 7. The limiting edge 5 / or the retaining edge 7 overlaps and limits the upper edge of the opening of the welding wire hopper 8 to prevent the wire feeder from being over-inserted. The installation method is simple and quick. The coiled welding wire inside the welding wire hopper 8 has outward tension, causing the hopper 8 to deform outward. At this point, the fixing part 2 is fitted onto the edge of the welding wire hopper 8. This prevents excessive deformation of the hopper 8 and, through the outward expansion of the hopper 8's sidewalls, increases the friction between the hopper 8 and the fixing part 2, ensuring the fixing part 2 is firmly installed and fixed to the hopper 8. This prevents the wire feed cap from falling off the hopper 8 during wire feeding. A wire feed tube from the welding equipment is connected to the outlet 4. The welding wire rises from inside the hopper 8 and exits through the outlet 4. As the wire gradually rises, if the coiled welding wire becomes loose, it will tend to move towards the inside of the dust cover 1. The conical dust cover 1 causes the loose welding wire to gradually separate from top to bottom, preventing mutual friction between the wires.

[0021] Furthermore, the larger end of the dust cover 1 is smaller than the inner diameter of the wire hopper 8. This causes the limiting edge 5 and / or the retaining edge 7 to protrude from the opening of the wire hopper 8, thus limiting the wire. The loose wire is obstructed by the limiting edge 5 and / or the retaining edge 7 as it moves upward, which separates adjacent coiled wires and allows them to gradually enter the dust cover 1. This further prevents the welding flux from falling off due to mutual friction between the wires, thereby preventing the wire from bending or knotting.

[0022] In a preferred embodiment, the fixing part 2 is formed by stacking clamping plates 9. A through hole 6 is located in the middle of the clamping plate 9. Side plates 10 and snap-fit ​​plates 11 are spaced around the through hole 6, with five of each. A snap-fit ​​protrusion 12 is provided on the side of the snap-fit ​​plate 11 away from the through hole 6, and a snap-fit ​​opening 13 that mates with the snap-fit ​​protrusion 12 is provided on the edge of the through hole 6 near the snap-fit ​​plate 11. The side plates 10 and snap-fit ​​plates 11 are bent downward to form the sidewall of the fixing part 2. Then, the two ends of the side plates 10 are bent toward the snap-fit ​​plate 11 and overlap with the snap-fit ​​plate 11. Then, the snap-fit ​​plate 11 is bent inward and upward to clamp the two ends of the side plates 10 in the middle. Finally, the snap-fit ​​protrusion 12 is snapped into the snap-fit ​​opening 13 to fix the side plates 10. At this time, the distance between the snap-fit ​​opening 13 and the through hole 6 forms the snap-fit ​​edge 7.

[0023] In a preferred embodiment, the height of the fixing part 2 is 72-78mm, preferably 74mm; the height of the dust cover is 290-300mm, preferably 296.6mm; and the diameter of the discharge port is 30mm.

[0024] In a preferred embodiment, an observation window 14 is provided on the side wall of the dust cover 1, and a transparent protective plate 15 is provided on the observation window 14. The observation window 14 allows workers to easily check the usage of the welding wire so that they can prepare more wire in advance when it is running low. It also allows them to check whether the welding wire is in a normal traction state and correct any bending or knotting that may occur. The protective plate 15 prevents dust from the workshop from entering the welding wire hopper.

[0025] In a preferred embodiment, mounting holes 16 are provided around the discharge port 4. The wire feeding tube of the external welding equipment is connected to the discharge port 4 through a connector (not shown in the figure), and the connector (not shown in the figure) is fixed in the mounting holes 16 by bolts. Further, the end of the connector (not shown in the figure) is arc-shaped, and the wire feeding tube of the welding equipment is fixedly connected to the upper end of the quick-connect connector.

[0026] When using it, lead the end of the welding wire out from the connector on the discharge port, then pass the dust cover 1 through the through hole 6, and then put the fixing part 2 on the opening of the welding wire hopper 8 to complete the installation of the wire feed cap. The process is simple and convenient.

[0027] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
