Description

Technical Field

[0001] The utility model relates to the technical field of bent pipes, in particular to a deformation-proof bent pipe device that is convenient to adjust. Background Art

[0002] When conducting failure analysis on faulty parts with a coating layer, it is necessary to observe and analyze the failure behavior of the substrate under the coating layer. Therefore, it is necessary to remove the surface coating layer. Currently, there are two commonly used methods for removing the coating layer. One is to grind off the coating layer by mechanical means that causes damage, but this will cause damage to the surface of the substrate under the coating layer and interfere with subsequent failure analysis work. The other is to use a chemical solvent to dissolve the coating layer on the surface of the faulty part, but this will cause new problems. First, the dissolution time is long, affecting the timeliness of the failure analysis work. Second, different solvents need to be equipped for different coating layers, and the method is complicated and time-consuming. Third, for a certain type of special substrate material, the solvent may also cause damage to its surface, which is not conducive to the subsequent work.

[0003] Therefore, there is an urgent need to design a method that can quickly and non-destructively remove the coating layer on the surface of the faulty part and will not cause damage to the surface of the substrate material under the coating layer. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model proposes a deformation-proof bent pipe device that is convenient to adjust.

[0005] A deformation-proof bent pipe device that is convenient to adjust includes a base, a workbench arranged on the base, several groups of legs arranged between the base and the workbench, and further includes a rotating disk rotatably arranged at the middle position of the upper end of the workbench. It also includes:

[0006] A rotation driving component, connected to the rotating disk, for providing the original driving force;

[0007] A pressing component, cooperating with the rotating disk, for realizing fine adjustment;

[0008] A protective insertion rod component, arranged at the outer side of the rotating disk at the position where the pipe port is inserted, which is convenient for adjustment to prevent the device from deforming during pipe bending;

[0009] A pushing component, arranged at the outer side of the rotating disk, for realizing sliding positioning.

[0010] Furthermore, a storage unit for storing protective insertion rods with different diameters is arranged on the outer side of the workbench. The storage unit includes two support bars vertically fixed on the outer side of the workbench, and each support bar is provided with a hanging support rod for holding the protective insertion rod.

[0011] Furthermore, the rotation driving component includes a transmission shaft fixedly connected to the middle position at the lower end of the rotating disc, a driven gear connected to the lower end of the transmission shaft, a rotating seat rotatably connected to the lower end of the transmission shaft and the upper end of the base, a driving gear meshing with the outer side of the driven gear, and a driving motor connected to the driving gear.

[0012] The beneficial effects of the present utility model are as follows: In response to the existing design requirements, the present utility model locks the starting position of the pipeline bend through the cooperation of the first positioning pressure roller and the pressing ring surface, locks and pulls the end of the pipeline through the second positioning pressure roller. When bending, the end of the pipeline is protected by inserting a rod through the protective inserting rod component, and then the rotating disc is driven to rotate by the rotation driving component. In this way, under the locking of the second positioning pressure roller, the pipeline will bend closely against the pressing ring surface; after bending, the diameter of the pressing ring surface can be reduced, which is convenient for taking away the processed pipeline. At the same time, the diameter of the bent pipe can be adjusted according to needs, improving the adaptability of processing. Brief Description of the Drawings

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below.

[0022] As Figures 1 to 6 shown, a pipe bending device that is easy to adjust and prevent deformation includes a base 13, a workbench 11 provided on the base 13, and a plurality of groups of support legs 12 provided between the base 13 and the workbench 11. It is characterized in that: it further includes a rotating disk 26 rotatably provided at the middle position of the upper end of the workbench 11, and further includes:

[0023] A rotation driving component, connected to the rotating disk 26, for providing the original driving force;

[0024] A pressing component, cooperating with the rotating disk 26, for realizing fine adjustment;

[0025] A protective insertion rod component, provided outside the rotating disk 26 at the position where the pipe port is inserted, which is convenient for adjustment and prevents the equipment from deforming during pipe bending;

[0026] A pushing component, provided outside the rotating disk 26, for realizing sliding positioning.

[0027] A storage unit for storing protective insertion rods 30 with different diameters is provided on the outside of the workbench 11. The storage unit includes two support bars 27 vertically fixed on the outside of the workbench 11, and each support bar 27 is provided with a hanging support rod 28 for holding the protective insertion rod 30. In this way, protective insertion rods 30 with different diameters can be clearly placed outside the equipment, which is convenient for later taking.

[0028] Four corner positions of the base 13 are respectively connected to the workbench 11 through the support legs 12 to complete the connection of the upper and lower components.

[0029] The described rotation drive component includes a transmission shaft 42 fixedly connected to the middle position at the lower end of the rotating disk 26, a driven gear 14 connected to the lower end of the transmission shaft 42, a rotating base 43 rotatably connected to the lower end of the transmission shaft 42 and the upper end of the base 13, a driving gear 16 meshing with the outside of the driven gear 14, and a driving motor 33 connected to the driving gear 16. The driving motor 33 drives the driving gear 16 to rotate, and the driving gear 16 and the driven gear 14 cooperate to drive the transmission shaft 42 to rotate. The upper end of the transmission shaft 42 can drive the rotating disk 26 to rotate, thereby providing power for pipe bending. Here, the diameter of the driven gear 14 is more than three times that of the driving gear 16 to reduce the load on the driving motor 33.

[0030] The described pressing component includes a mounting ring cylinder 41 coaxially arranged with the upper end of the rotating disk 26, several groups of movable pressing wheels 40 arrayed on the outside of the mounting ring cylinder 41, and a fine-tuning component 25 arranged on the mounting ring cylinder 41 for driving the radial movement of the position of the movable pressing wheels 40 to adjust the diameter of the pressing ring surface. In this way, it can adapt to pipe fittings with different bending radii, expanding the processing range of the product.

[0031] Multiple movable pressing wheels 40 form a pressing ring surface matching the pipe bending radius.

[0032] The described fine-tuning component 25 includes multiple horizontal sliding holes arranged on the mounting ring cylinder 41, horizontal sliding posts 35 slidably arranged in each horizontal sliding hole, a reset block 37 arranged at the upper end of the horizontal sliding post 35, a reset spring 36 arranged between the mounting ring cylinder 41 and the reset block 37, a connecting shaft 401 arranged at the outer end of the horizontal sliding post 35 for connecting the movable pressing wheel 40, a mounting groove 39 arranged at the inner end of the horizontal sliding post 35, and guide wheels 38 rotatably arranged at each mounting groove 39 position. Above the mounting ring cylinder 41, a pushing component is provided for generating a thrust force on the multiple guide wheels 38.

[0033] The horizontal sliding holes are arrayed on the outside of the mounting ring cylinder 41.

[0034] The described pushing component includes a conical column 24 arranged above the mounting ring cylinder 41, a lifting push rod 23 connected to the conical column 24, and a mounting bracket 22 for mounting the lifting push rod 23. To improve the mechanical properties of the product, at least two reinforcing ribs 21 are provided between the mounting bracket 22 and the positioning vertical plate 111.

[0035] One end of the mounting bracket 22 is connected to the positioning vertical plate 111 at the upper end of the workbench 11. The conical column 24 is a conical column body with a narrow lower end and a wide upper end. When the conical column 24 is driven by the lifting push rod 23 to move downward, the diameter of the contact between the conical column 24 and the guide wheel 38 will become larger and larger, thereby forcing the multiple movable pressing wheels 40 to move radially outward simultaneously to complete the adjustment of the bending radius.

[0036] The described protective insertion rod component includes a fine-tuning base 32 arranged on the side surface of the rotating disk 26, a fine-tuning sliding groove 31 arranged at the upper end of the fine-tuning base 32, and a movable vertical plate 20 slidably arranged in the fine-tuning sliding groove 31.

[0037] The bottom of the movable vertical plate 20 and the cross-section of the fine-tuning sliding groove 31 are both T-shaped. A through hole 301 facilitating the installation of the protective insertion rod 30 is arranged on the movable vertical plate 20. A rubber ring 302 is arranged on the inner wall of the through hole. The rubber ring 302 can deform to match rods of different diameters. In this way, the protective insertion rod 30 can be replaced according to different bent pipes. When bending, the protective insertion rod 30 is inserted into the end of the pipe to protect the end of the pipe. After the protective insertion rod 30 is inserted into the end of the pipe, it can move along with the pipe. Therefore, there is no need to lock the position of the protective insertion rod 30 too tightly here.

[0038] The described pushing component includes a second positioning pressure roller 19 arranged outside the rotating disk 26, a second telescopic push rod 34 connected to the second positioning pressure roller 19 for driving its horizontal movement, a positioning slider 15 slidably arranged on the upper end of the workbench 11, and a first telescopic push rod 17 connected to the positioning slider 15 for pushing it towards the rotating disk 26. A first positioning pressure roller 18 corresponding to the pressing ring surface is arranged on the upper end of the positioning slider 15. The starting position of the bending of the pipe is locked by the cooperation of the first positioning pressure roller 18 and the pressing ring surface. The end of the pipe is locked and pulled by the second positioning pressure roller 19. When bending, the end of the pipe is protected by inserting a rod through the protective insertion rod component. Then, the rotating disk 26 is driven to rotate by the rotating drive component. In this way, under the locking of the second positioning pressure roller 19, the pipe will be bent closely against the pressing ring surface; after bending, the diameter of the pressing ring surface can be reduced, so as to facilitate taking away the processed pipe.

[0039] The first positioning pressure roller 18, the second positioning pressure roller 19, and the movable pressure wheel 40 are all arc-shaped structures with wide ends and narrow middles.

[0040] When bending, the end of the pipe is protected by inserting a rod through the protective insertion rod component. Specifically, a protective insertion rod 30 matching the inner diameter of the pipe is rotated and inserted into the end of the pipe. The outer end of the pipe is tightly pressed and fixed by the first positioning pressure roller 18 and the second positioning pressure roller 19. Then, the rotating disk 26 is driven to rotate by the rotating drive component. In this way, under the locking of the second positioning pressure roller 19, the pipe will be bent closely against the pressing ring surface; after bending, the diameter of the pressing ring surface can be reduced, so as to facilitate taking away the processed pipe.
