Description

Technical Field

[0001] The utility model relates to the field of pipe fitting production, in particular to a vertical press-fitting fixture for steel-plastic conversion pipe fittings. Background Art

[0002] The vertical press-fit clamp for steel-plastic conversion pipe fittings is a tool used to fix and press-fit steel-plastic conversion pipe fittings during pipeline installation. This clamp is usually designed to connect steel pipes to plastic pipes and ensure a firm connection and reliable sealing. When producing and processing steel-plastic conversion pipe fittings, a vertical press-fit clamp is required, which can simplify the pipeline installation process, improve connection efficiency and quality, ensure the sealing and reliability of the connection, thereby reducing the maintenance cost and safety risks of the pipeline system.

[0003] However, most of the vertical press-fit fixtures for steel-plastic conversion pipe fittings currently have the following problems:

[0004] For example, a vertical pressing fixture for steel-plastic conversion pipe fittings with publication number CN202020576460.X can clamp and limit the steel-plastic conversion pipe fittings through the cooperation of the first clamp and the second clamp, but the steel-plastic conversion pipe fittings have different diameters. If the steel-plastic conversion pipe fittings are larger or smaller, it is easy for them to be unable to be firmly clamped and limited, affecting the subsequent vertical pressing and making it inconvenient to perform convenient limiting clamping; at the same time, the space under the connecting plate is limited. If the steel-plastic conversion pipe fittings to be processed are long, it is easy for them to be unable to be fully placed, affecting the stability of the equipment and making it inconvenient to adjust the use space of the equipment.

[0005] Therefore, we make improvements on this and propose a vertical press-fit fixture for steel-plastic conversion pipe fittings. Utility Model Content

[0032] Embodiment 2:

[0033] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0034] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the guide blocks 3 are symmetrically distributed on the left and right sides of the extension frame 2, and the guide blocks 3 correspond one-to-one with the connecting rods 6 through the limit plates 5, which can ensure that the connecting rods 6 on both sides can pull the pull plates 7 for smooth movement.

[0035] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the cross-section of the guide block 3 is "T"-shaped, and the side end face of the limiting plate 5 is fitted with the inner side face of the guide block 3, which can ensure that the "T"-shaped guide block 3 can slide smoothly on the inside of the protective shell 1.

[0037] like Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the moving block 15 is in contact with the inner side face of the mounting frame 11, and the cross-section of the clamping block 20 is an isosceles triangle, which can ensure that the isosceles triangle clamping block 20 can move smoothly under the push of the clamping plate 21.

[0038] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, a guide rod 22 is fixedly connected to the splint 21, and the guide rod 22 is limitedly slidably connected to the mounting frame 11 and the mounting plate 17, and the guide rods 22 are symmetrically distributed on the upper and lower sides of the splint 21, which can ensure that the splint 21 can move smoothly with the support of the guide rods 22 on both sides when moving.

[0039] Specifically, when using the vertical press-fit fixture for steel-plastic conversion pipe fittings: Figure 1-4 When processing the steel-plastic conversion pipe fittings, open the protective door on the protective shell 1, place the steel-plastic conversion pipe fittings on the support plate 23, and then turn on the servo motor 12 on the mounting frame 11. The servo motor 12 drives the bidirectional threaded rod 13 to operate. At the same time, the bidirectional threaded rod 13 can drive the bidirectional threaded rods 13 on both sides to rotate simultaneously through the transmission belt 14. When the bidirectional threaded rod 13 rotates, it can drive the moving blocks 15 on both sides to move. When the moving blocks 15 on both sides move inward, they can push the mounting plate 17 to move through the push plate 16. When the mounting plate 17 moves, it can drive the installed clamping plate 21 to move simultaneously. The clamping plate 21 can clamp the placed steel-plastic conversion pipe fittings. While clamping, continue to apply pressure on the steel-plastic conversion pipe fittings to push the clamping plate 21 to move. When the clamping plate 21 moves, it can push the clamping block 20 to move inward. At the same time, the clamping block 20 pulls the second spring 18 through the slider 19. The clamping block 20 can clamp the left and right sides of the steel-plastic conversion pipe, align and limit the steel-plastic conversion pipe fittings, and can clamp and limit steel-plastic conversion pipe fittings of different sizes to improve the installation stability. Then the hydraulic cylinder 9 on the extension frame 2 is turned on, and the hydraulic cylinder 9 drives the pressure plate 10 to move downward. When the pressure plate 10 moves, the placed steel-plastic conversion pipe fittings can be vertically pressed. When taking out the steel-plastic conversion pipe fittings, the two-way threaded rod 13 can be driven to operate in the opposite direction. The two-way threaded rod 13 drives the moving blocks 15 on both sides to move outward. At the same time, the moving blocks 15 pull the mounting plate 17 through the push plate 16 to reset. When the clamping plate 21 is not hindered, the slider 19 is driven to reset under the pull of the second spring 18. At the same time, the slider 19 drives the clamping block 20 and the clamping plate 21 to reset. When the clamping plate 21 moves, it can move smoothly under the guidance of the guide rod 22, so the steel-plastic conversion pipe fittings can be installed and processed smoothly.

[0040] If the steel-plastic conversion pipe fittings to be processed are long and the use space needs to be adjusted, the pull plates 7 on both sides can be pulled. The pull plates 7 drive the limit plates 5 to move through the connecting rods 6. At the same time, the limit plates 5 can squeeze the first spring 4. The pulled pull plates 7 will separate the installed block 8 from the protective shell 1. When the extension frame 2 is not hindered by the guide block 3, the use position of the extension frame 2 can be adjusted. After the adjustment is completed, release the pull plates 7 and drive the limit plates 5 to reset under the push of the first spring 4. When the limit plates 5 move, they can be reset by pulling the pull plates 7 through the connecting rods 6. The pull plates 7 can engage the block 8 in the protective shell 1, and fix the adjusted extension frame 2 to facilitate adjustment according to usage.

[0041] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods.
