Description

Technical Field

[0001] This utility model relates to the technical field of high-frequency welding machines, specifically to a high-frequency welding machine for H-type ribbed tubes. Background Technology

[0002] Existing high-frequency welding machines involve axially fixing the steel pipe to be welded onto the machine. Following the welding rhythm, the operator holds a rib in each hand, placing it into a chute. The rib slides along the chute onto the electrode plate of the high-frequency welding machine. At the electrode plate, under the action of high-frequency voltage, the steel pipe and rib are welded together. After welding, the steel pipe moves forward, requiring manual repositioning of the welded rib into the chute. The operator must stand beside the machine and repeat this process, placing the rib one by one. This requires one employee per machine. With multiple identical high-frequency welding machines in the workshop, multiple employees are needed, resulting in a significant expenditure of manpower and time to meet production demands. See the specific structure below. Figure 5 Therefore, it is necessary to propose a high-frequency welding machine for H-type ribbed tubes to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an H-type ribbed tube high-frequency welding machine, comprising a base and a top platform assembly positioned above the base. The top platform assembly includes two top platforms arranged in a mirror image configuration. Each of the two top platforms has a propulsion device on its sidewall. Each top platform has a pneumatic device above it, comprising a cylinder head and a push rod head. The push rod head has a sliding structure. A rib storage box is located on the top platform near the pneumatic device. A rib buffer box is located on the side of the rib storage box away from the pneumatic device. A groove structure is located below the rib buffer box. Each propulsion device is connected to a pull rod, and each pull rod is connected to an electrode plate. A baffle pushing device is located on one side of each electrode plate, allowing the ribs to slide into the electrode plate within the groove structure.

[0004] A further improvement of this utility model is that: two limiting groove structures are provided at the opposite positions of the two electrode plates, the longitudinal section of the limiting groove structure is a semi-circular structure, and the semi-circular structure on the limiting groove structure corresponds to the semi-circular structure on the rib.

[0005] A further improvement of this utility model is that the rib buffer box is the same size as the rib.

[0006] A further improvement of this utility model is that the left and right sides of the rib buffer box are mirror images of each other, and the rib buffer box and the rib storage box are connected by a fixed method.

[0007] A further improvement of this utility model is that the rib storage box has two groove-shaped structures inside, which are used to accommodate the two sides of the rib.

[0008] A further improvement of this utility model is that the baffle pushing device includes a baffle structure and a pushing rod connected to the baffle structure, and the pushing rod is connected to the pushing device.

[0009] A further improvement of this utility model is that the longitudinal section of the baffle structure is L-shaped, and the baffle structure just blocks the front end face of the electrode plate when pushed to the maximum path.

[0010] Beneficial effects:

[0011] This invention involves stacking ribs in a storage box according to a certain direction. A cylinder pusher pushes the ribs into a rib buffer box, where they slide along the buffer box into a groove structure. The ribs then slide along the groove structure to the electrode plate, where a steel pipe is welded to them. After welding, the steel pipe moves forward, and the ribs repeat the above movements for further welding. This allows for continuous stacking and feeding, accommodating welding for extended periods. Furthermore, one person can simultaneously oversee multiple machines, improving work efficiency, reducing labor hours, lowering production costs, and enhancing product competitiveness.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] This utility model relates to an H-type ribbed tube high-frequency welding machine, including a base 1 and a top platform group 2 disposed above the base 1. The top platform group 2 includes two top platforms 3 arranged in a mirror manner. Each of the two top platforms 3 has a pushing device 4 on its side wall. Each top platform 3 has a pneumatic device 5 above it. The pneumatic device 5 includes a cylinder head 6 and a push rod head 7. The push rod head 7 has a sliding structure. A rib storage box 8 is disposed on the top platform 3 near the pneumatic device 5. A rib buffer box 9 is disposed on the side of the rib storage box 8 away from the pneumatic device 5. A sliding groove structure 10 is disposed below the rib buffer box 9. Each pushing device 4 is connected to a pull rod 11. Each pull rod 11 is connected to an electrode plate 12. Each electrode plate 12 has a baffle pushing device 13 on one side. Ribs 14 slide into the interior of the electrode plate 12 within the sliding groove structure 10.

[0020] Each of the two electrode plates 12 has two limiting groove structures 15 at opposite positions. The longitudinal section of the limiting groove structure 15 is a semi-circular structure 16. The semi-circular structure 16 on the limiting groove structure 16 corresponds to the semi-circular structure 17 on the rib 14. The rib buffer box 9 is the same size as the rib 14. The left and right sides of the rib buffer box 9 are mirror images of each other. The rib buffer box 9 is fixedly connected to the rib storage box 8.

[0021] The purpose of the pneumatic device 5 is to push the ribs 14 stored in the rib storage box 8 out of the rib storage box 8 through the push rod head 7 on the cylinder head 6. The ribs 14 fall into the rib buffer box 9. To achieve this purpose, a suitable cylinder is selected, and the push rod head 7 is designed on the cylinder head 6. The push rod head 7 is made into a slider type. It moves back and forth along the slider and pushes the push rod head 7 into the groove structure 18 of the rib storage box 8. The cylinders on the left and right sides are connected in series. When the cylinder pushes the ribs 14 on both sides, they fall into their respective rib buffer boxes 9 at the same time. The cylinder pushes the rib 14 once, and the rib 14 falls into the rib buffer box 9 once. The action is repeated in a cycle.

[0022] The purpose of designing the rib buffer box 9 is to push the ribs 14 stored in the rib storage box 8 into the rib buffer box 9 through the push rod head 7. Along the trajectory of the rib buffer box 9, the ribs 14 slide into the electrode plate 12 along the sliding groove structure 10. The ribs 14 are then high-frequency welded to the steel pipe. To achieve this purpose, the size of the rib buffer box 9 is designed to be the same as the size of the ribs 14. The left and right sides of the rib buffer box 9 are mirror images of each other. The rib buffer box 9 is fixed together with the rib storage box 8, and the ribs 14 are pushed into the rib buffer box 9 by the push rod head 7.

[0023] The purpose of designing the rib storage box 8 is to store more ribs 14 at once, reducing the number of times personnel need to fill the ribs 14, thus improving work efficiency. Simultaneously, according to the needs of high-frequency welding machine processing, one set of the rib storage box 8 is designed on each of the top platforms on the left and right sides of a high-frequency welding machine. The size of the rib storage box 8 can be designed according to the size requirements of the ribs 14, and the height of the rib storage box 8 is designed according to the consumption time of the ribs 14. After the rib storage box 8 is designed and processed, it is welded firmly onto the top platform of the high-frequency welding machine according to the processing position requirements.

[0024] Personnel manually take the pre-prepared ribs 14 and stack them in a certain direction into the rib storage boxes 8 on both sides. Since the rib storage boxes 8 are designed for visibility, it is visible when the rib storage boxes 8 are full of ribs 14. The rib storage boxes 8 have two slot-shaped structures 18 inside to accommodate the two sides of the ribs 14. The baffle pushing device 13 includes a baffle structure 19 and a pushing rod 20 connected to the baffle structure 19. The pushing rod 20 is connected to the pushing device 13. The longitudinal section of the baffle structure 19 is L-shaped. When the baffle structure 19 is pushed to the maximum path, it just blocks the front end of the electrode plate 12.

[0025] Working principle:

[0026] The ribs 14 are stacked in a certain direction in the storage box. According to the welding rhythm, the pneumatic device 5 pushes the ribs 14 one by one into the rib buffer box 9. The ribs slide along the trajectory of the rib buffer box 9 into the sliding groove structure 10. The ribs 14 then slide along the sliding groove structure 10 to the electrode plate 12. Under the action of high frequency voltage, the steel pipe 21 and the ribs 14 are welded. After welding, the steel pipe 21 moves forward and the ribs 14 repeat the above movement to weld again.

[0027] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
