Description

Technical Field

[0001] This utility model relates to the field of welding wire hopper technology, and in particular to a punching and grooving device for the inner hopper of a welding wire hopper. Background Technology

[0002] The welding wire hopper is a key component in welding equipment used for storing and feeding welding wire. Its structural design directly affects the stability of the welding wire, the smoothness of wire feeding, and the welding quality. Based on structural characteristics, welding wire hoppers are mainly divided into single-layer and double-layer hoppers. A single-layer hopper consists of a single hopper body with the welding wire directly wound inside, without any layering or isolation structure. A double-layer hopper consists of two hopper bodies, with the inner hopper fixed to the bottom or a bottom mounting plate, and the outer hopper possibly serving as a protective cover or auxiliary structure. In double-layer hoppers, a pull rod is typically installed inside the inner hopper, and symmetrical vertical slots are cut into the inner hopper wall. These slots provide a fixed guide track for the pull rod, ensuring that it can only move vertically along the path of the slot and presses against the surface of the welding wire, using its own weight or external force to fix the welding wire and prevent it from bouncing or becoming tangled. In addition, through holes are made on the inner wall of the welding wire canister so that the end of the welding wire can be inserted into the through holes. This ensures that the welding wire is wound in a controlled and orderly manner inside the canister. At the same time, when the operator uses the welding wire, the starting end of the welding wire is provided with a fixed anchor point, which can facilitate quick positioning of the welding wire head, improve wire loading efficiency and welding stability.

[0003] Therefore, the stamping of the through holes and vertical slots in the inner barrel of the welding wire hopper is fundamental to ensuring subsequent welding and assembly processes. Currently, the stamping of the through holes and vertical slots in the inner barrel of the welding wire hopper is done separately, using different equipment or workstations. This results in low production efficiency, and it is difficult to guarantee the positioning accuracy and motion synchronization between the equipment or workstations. Consequently, the symmetry and precision of the through holes and vertical slots cannot be guaranteed. This can lead to disordered winding paths due to deviations in the starting point position during the welding wire winding process, potentially causing tangled wires and uneven wire delivery, thus affecting the user experience.

Detailed Implementation

[0017] This utility model provides a punching and grooving device for the inner barrel of a welding wire drum, such as... Figures 1-4 As shown, the system includes a base 1 connected to a rectangular three-dimensional frame 2, which is a cuboid structure. A mold cylinder 3 is mounted on the base 1 and located within the rectangular three-dimensional frame 2, fixed to the top surface of the base 1. The mold cylinder 3 matches and is used to fit the inner barrel of the welding wire hopper (not shown). During the punching and grooving operation, the operator places the inner barrel of the welding wire hopper onto the outer wall of the mold cylinder 3. Additionally, the inner wall of the upper part of the inner barrel of the welding wire hopper has an inner protrusion (not shown) along the circumferential direction. When the inner barrel of the welding wire hopper is fitted onto the outer wall of the mold cylinder 3, the inner protrusion abuts against the edge of the upper opening of the mold cylinder 3, thus securing the inner barrel of the welding wire hopper. Cylinders 4 are symmetrically arranged on the front and rear sides of the rectangular three-dimensional frame 2 along the diameter direction of the mold cylinder 3. The movable end of the cylinder 4 is horizontally positioned and connected to the punch 5. Mold holes 6 are symmetrically arranged on the mold cylinder 3. The mold holes 6 correspond to and follow the shape of the punch 5 on the same side, that is, the size of the mold holes 6 matches the punch 5. Specifically, the front and rear sides of the rectangular three-dimensional frame 2 are symmetrically provided with first through holes 7. The movable end of the cylinder 4 can pass through the first through holes 7 so that the movable end of the cylinder 4 can move horizontally within the first through holes 7. When the cylinder 4 is started, the horizontal movement of the movable end of the cylinder 4 will drive the punch 5 to move horizontally. U-shaped plates 8 are fixed to the inner walls of the front and rear sides of the rectangular three-dimensional frame 2. The U-shaped plates 8 are provided with positioning holes 9. The punch 5 can pass through the first through hole 7, the positioning hole 9 and the mold hole 6 on the same side in sequence. The setting of the positioning hole 9 ensures the accuracy of the horizontal movement of the punch 5. During the drilling operation, the inner barrel of the welding wire hopper to be processed is fitted onto the outer wall of the mold cylinder 3. The cylinder 4 is activated, and the movable end of the cylinder 4 extends, causing the punch 5 to move toward the inner barrel of the welding wire hopper. This allows the punch 5 to pass through the positioning hole 9 and drill a hole in the inner barrel of the welding wire hopper. Once the punch 5 passes through the mold hole 6, the drilling operation of the inner barrel of the welding wire hopper is completed, and the movable end of the cylinder 4 can be retracted and reset.

[0018] Hydraulic cylinders 10 are symmetrically arranged on the left and right sides of the rectangular three-dimensional frame 2 along the diameter direction of the mold cylinder 3. The movable end of the hydraulic cylinder 10 is horizontally set and connected to the grooving cutter 11. The length direction of the grooving cutter 11 is vertical. Thus, the movement of the grooving cutter 11 will cut a vertical through groove on the inner barrel of the welding wire drum. The mold cylinder 3 is symmetrically provided with mold grooves 12, which correspond to and follow the shape of the grooving cutter 11 on the same side. Specifically, the left and right sides of the rectangular three-dimensional frame 2 are symmetrically provided with second through holes 13. Positioning frames 14 are fixed to the inner walls of the left and right sides of the rectangular three-dimensional frame 2. The movable end of the hydraulic cylinder 10 passes through the second through hole 13 and is connected to the positioning plate 15, the positioning plate 16 and the grooving cutter 11 in sequence. The positioning frame 14 is provided with a positioning groove 17, which follows the shape of the grooving cutter 11. The setting of the positioning groove 17 ensures the accuracy of the horizontal movement of the grooving cutter 11, and the grooving cutter 11 can pass through the positioning groove 17 and the mold groove 12. During the grooving operation, the inner barrel of the welding wire hopper to be processed is placed on the outer wall of the mold cylinder 3. The hydraulic cylinder 10 is activated, and the extended end of the hydraulic cylinder 10 will drive the positioning plate 15, the positioning plate 16, and the grooving knife 11 to move. This causes the grooving knife 11 to pass through the positioning groove 17 and groov the inner barrel of the welding wire hopper. When the grooving knife 11 passes through the mold groove 12, the grooving operation of the inner barrel of the welding wire hopper is completed, and the extended end of the hydraulic cylinder 10 can be retracted and reset.

[0019] Punch 5 and grooving cutter 11 are located on the outside of mold cylinder 3 and spaced apart from it. Positioning frame 14 and U-shaped plate 8 are also spaced apart from mold cylinder 3 to facilitate the placement of the inner barrel of the welding wire hopper onto mold cylinder 3 within the intervals. The symmetrical arrangement of punch 5 and grooving cutter 11 ensures the symmetrical precision of the through holes and vertical slots in the inner barrel of the welding wire hopper, guaranteeing smooth wire output and preventing wire tangling. Additionally, cylinder 4 and hydraulic cylinder 10 are connected to a control box (not shown). Sensors (not shown) are installed on cylinder 4 and hydraulic cylinder 10, and these sensors are connected to the control box. In this embodiment, the control box is a PLC control box. When cylinder 4 and hydraulic cylinder 10 are started via the control box, and the movable end of cylinder 4 extends to drive punch 5 to complete punching, while the movable end of hydraulic cylinder 10 extends to drive grooving knife 11 to complete grooving, the sensor sends a corresponding signal to the control box. The control box controls the movable ends of cylinder 4 and hydraulic cylinder 10 to retract and reset. Through the control box, punching and grooving operations of the inner barrel of the welding wire hopper can be controlled simultaneously, improving production efficiency.

[0020] A fixing sleeve 18 is fitted onto the bottom of the mold cylinder 3, and the fixing sleeve 18 is fixedly connected to the base 1 to make the mold cylinder 3 more securely connected to the base 1. An arc-shaped support plate 19 is also fitted onto the mold cylinder 3. The arc-shaped support plate 19 is located above the fixing sleeve 18 and can move up and down along the mold cylinder 3. When the inner barrel of the welding wire hopper to be processed is fitted onto the mold cylinder 3, the bottom of the inner barrel of the welding wire hopper will abut against the upper surface of the arc-shaped support plate 19. The up and down movement of the arc-shaped support plate 19 along the mold cylinder 3 will drive the inner barrel of the welding wire hopper to move up and down. The punching and grooving device in this embodiment also includes a pusher cylinder 204. The movable end of the pusher cylinder 204 is vertically set and fixedly connected to the top surface of the fixing plate 29. The arc-shaped support plate 19 has a protrusion 21, and the protrusion 21 is fixedly connected to the bottom surface of the fixing plate 29. This design ensures that after the inner barrel of the welding wire hopper is processed, the movable ends of cylinder 4 and hydraulic cylinder 10 retract and reset simultaneously. The upward movement of the movable end of the pusher cylinder 204 moves the arc-shaped support plate 19 upward, thereby causing the inner barrel of the welding wire hopper to move upward. The operator can then remove the processed inner barrel of the welding wire hopper. After approximately 3 seconds, the movable end of the pusher cylinder 204 moves downward and resets, making the operation more convenient. Specifically, the fixed end of the pusher cylinder 204 is fixed to the outer wall of the front or rear side of the rectangular three-dimensional frame 2. The fixed end of the pusher cylinder 204 includes a fixed block 22, with a vertically hollow guide sleeve 23 in the middle of the fixed block 22. Vertically oriented guide through holes 24 are symmetrically provided on both sides of the fixed block 22. The movable end of the pusher cylinder 204 includes a first sliding rod 25 and two second sliding rods 26. The two second sliding rods 26 are symmetrically arranged on both sides of the first sliding rod 25. The first sliding rod 25 matches the guide sleeve 23 and can move up and down within the guide sleeve 23. The second sliding rods 26 match the guide through hole 24 and can move up and down within the guide through hole 24. By setting the first sliding rod 25 and the two second sliding rods 26 to move up and down, the accuracy of the vertical movement of the inner barrel of the welding wire hopper is further ensured. The top of the second sliding rod 26 is connected to the limiting block 27, which limits the downward movement of the second sliding rod 26. In addition, the top of the rectangular three-dimensional frame 2 is connected to a cover plate 28, which protects the components inside the rectangular three-dimensional frame 2 and also protects the operator.

[0021] The punching and grooving device for the inner barrel of a welding wire hopper provided by this utility model is used by the operator to place the inner barrel of the welding wire hopper to be processed onto the outer wall of the mold cylinder 3 for fixation. The operator then activates the cylinder 4 and the hydraulic cylinder 10 via the control box. This causes the movable end of the cylinder 4 to extend, driving the punch 5 to complete the punching, while the movable end of the hydraulic cylinder 10 extends, driving the grooving cutter 11 to complete the grooving. Simultaneously, the sensor sends a corresponding signal to the control box, which then controls the movable ends of the cylinder 4 and the hydraulic cylinder 10 to retract and reset. Once the inner barrel of the welding wire hopper has completed punching and grooving, the pusher cylinder 204 is activated via the control box. The first sliding rod 25 and the two second sliding rods 26 of the pusher cylinder 204 move upward, causing the arc-shaped support plate 19 to move upward, thereby moving the completed inner barrel of the welding wire hopper upward. The operator can then easily remove the inner barrel of the welding wire hopper. After the pusher cylinder 204 is reset, the operator can then place the next inner barrel of the welding wire hopper to be processed on the outer wall of the mold cylinder 3 for punching and grooving operations.
