Description

Technical Field

[0001] This utility model relates to the field of steel pipe punching technology, specifically a steel pipe punching die mechanism with rotary adjustment. Background Technology

[0002] Steel pipes are steel materials with hollow cross sections, whose length is much greater than their diameter or circumference. They are classified into circular, square, rectangular, and irregular-shaped steel pipes according to their cross-sectional shape. Steel pipes have many applications. In some application fields, steel pipe fittings need to be punched on their surface to facilitate subsequent use.

[0003] The existing patent publication number CN213615319U discloses a stainless steel pipe punching die, which includes a base and an arc-shaped pressing component. The arc-shaped pressing component has an installation groove. A telescopic rod is fixedly connected to the bottom of the installation groove, and a first arc-shaped block is fixedly connected to one end of the telescopic rod. Connecting rods are symmetrically arranged on the bottom sidewalls of the installation groove on both sides of the telescopic rod, and a second arc-shaped block is fixedly connected to one end of each connecting rod. The arc shape of the first arc-shaped block matches that of the second arc-shaped block. An arc-shaped groove is opened on the sidewall of the base located directly below the arc-shaped pressing component, and a limit device is fixedly connected to the base on one side of the arc-shaped groove.

[0004] While the aforementioned patents facilitate the clamping and fixing of stainless steel pipes of different diameters, making the equipment more versatile, the punching positions of the steel pipes may not be limited to one side. Therefore, a side-changing operation is required during punching. The aforementioned patents do not have the function of rotating the steel pipe; they require releasing the steel pipe first, then rotating it, and then fixing it again, which is relatively cumbersome and reduces punching efficiency. To address this issue, we provide a rotating and adjustable steel pipe punching die mechanism. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-2 As shown, a rotary adjustable steel pipe punching die mechanism includes a worktable 1. Support legs 2 are installed around the lower end of the worktable 1. A base plate 8 is connected between the support legs 2. A displacement mechanism 9 is installed on the upper end of the base plate 8. The displacement mechanism 9 includes a servo motor 91 installed on the upper end of the base plate 8. A lead screw 92 is connected to the output end of the servo motor 91. A support seat 93 rotatably connected to the lead screw 92 is installed on the upper end of the base plate 8. A threaded block 94 is screwed to the outer side of the lead screw 92. A support rod 95 is connected to the upper end of the threaded block 94. The upper end of the support rod 95 passes through the first movable groove 10 and is connected to the fixed seat 31.

[0026] The output of the servo motor 91 drives the lead screw 92 to rotate, while the threaded block 94 on the outside of the lead screw 92 moves left and right. At the same time, the threaded block 94 drives the support rod 95 through the first movable groove 10 to drive the fixed seat 31 and the entire clamping mechanism 3 to move left and right, so that the clamping mechanism 3 can move the steel pipe to perform punching operations at different positions.

[0027] Please see Figure 1 , Figure 3-4As shown, the upper end of the workbench 1 is provided with a first movable groove 10 and a second movable groove 11. The upper end of the displacement mechanism 9 passes through the first movable groove 10 and is connected to a clamping mechanism 3. The clamping mechanism 3 includes a fixed seat 31 connected to the displacement mechanism 9. A convex hole 32 is provided on the outer side of the fixed seat 31. The inner cavity of the convex hole 32 is rotatably connected to a clamping assembly 34 through a bearing 33. The clamping assembly 34 includes a circular sleeve 341 connected to a connecting rod 35. The circular sleeve 341 is rotatably connected to the bearing 33. Three sets of elongated grooves 343 are equidistantly provided on the outer side of the circular sleeve 341. A sealing plate 342 is connected to one end of the circular sleeve 341. The inner cavity of the circular sleeve 341 is movably fitted with the movable plate 344. A slot 345 is provided on the outer side of the movable plate 344. Three sets of first connecting parts 346 are equidistantly installed on the side corresponding to the movable plate 344. Each first connecting part 346 is movably connected to a movable rod 347 via a connecting shaft. Three sets of arc-shaped plates 349 are equidistantly arranged on the outer side of the circular sleeve 341, corresponding to the position of the long groove 343. Each arc-shaped plate 349 is equipped with a second connecting part 348 at one end. Each second connecting part 348 is rotatably connected to two movable rods 347 via a connecting shaft. An mounting plate 38 is installed on the outer side of the fixed seat 31. A translation cylinder 39 is installed on the upper end of the mounting plate 38. The output end of the translation cylinder 39 corresponds to the position of the movable plate 344. A sliding column 310 is equidistantly connected on one side of the fixed sleeve 36. An annular groove 37 is provided on the outer side of the fixed seat 31 for sliding contact with it.

[0028] By inserting one end of the steel pipe into the inner cavity of the fixed sleeve 36, and then opening the translation cylinder 39, the output end of the translation cylinder 39 is inserted into the slot 345 on the outside of the movable plate 344. This causes the movable plate 344 to move towards the sealing plate 342. Consequently, the first connecting piece 346 on the outside of the movable plate 344 moves one end of the movable rod 347 connected to it upwards. This causes the first connecting piece 346 on the outside of the sealing plate 342 to move one end of the movable rod 347 connected to it upwards simultaneously. Consequently, the two sets of movable rods 347 move the second connecting piece 348 and the arc plate 349 on its upper end that are rotatably connected to it upwards. Thus, the three sets of arc plates 349 support and clamp the inner cavity of the steel pipe, which is convenient for supporting and clamping steel pipes of different inner diameters, effectively improving practicality.

[0029] Please see Figure 3As shown, connecting rods 35 are equidistantly arranged on the outer side of the clamping assembly 34. A fixing sleeve 36 is connected to the outer side of the connecting rods 35. A rotating assembly 4 is installed on the outer side of the fixing sleeve 36. The rotating assembly 4 includes an L-shaped plate 41 installed on the upper end of the fixing seat 31. A first lifting cylinder 42 is installed on the upper end of the L-shaped plate 41. A support plate 43 is connected to the output end of the first lifting cylinder 42. A rack 44 is connected to the lower end of the support plate 43. A gear ring 45 is installed on the outer side of the fixing sleeve 36. The lower end of the rack 44 passes through the fixing seat 31 and extends below it to mesh with the gear ring 45. A limit post 46 is connected to the upper end of the support plate 43. The upper end of the limit post 46 passes through the L-shaped plate 41 and extends above it. The lower end of the rack 44 corresponds to the position of the second movable groove 11.

[0030] When the steel pipe needs to be rotated and its position adjusted, the output end of the first lifting cylinder 42 drives the support plate 43 to move up and down. The limiting post 46 at the upper end of the support plate 43 passes through the L-shaped plate 41 to limit and stabilize its movement. When the rack 44 at the lower end of the support plate 43 moves up and down, it drives the meshing gear ring 45 and the fixing sleeve 36 to rotate. The fixing sleeve 36 drives the entire clamping assembly 34 and the steel pipe to rotate through the connecting rod 35, which makes it easy to rotate and adjust the side of the steel pipe that needs to be punched to be directly below the punching assembly 7, which is convenient for punching operations. The sliding post 310 on the outside of the fixing sleeve 36 slides in the inner cavity of the annular groove 37 on the outside of the fixing seat 31, which effectively improves the stability of the rotation of the fixing sleeve 36.

[0031] Please see Figure 5 As shown, a support component 5 is provided at the upper end of the workbench 1. The support component 5 includes a second lifting cylinder 51 installed at the lower end of the workbench 1. The output end of the second lifting cylinder 51 passes through the workbench 1 and is connected to a V-shaped plate 52. A positioning column 53 is symmetrically connected to the lower end of the V-shaped plate 52. The lower end of the positioning column 53 passes through the workbench 1 and extends below it.

[0032] Depending on the size of the steel pipe, the output end of the second lifting cylinder 51 drives the V-shaped plate 52 to move up and down until it fits against the outer surface of the steel pipe, thereby facilitating stable support for the steel pipe and enabling it to move, rotate, and punch.

[0033] A top frame 6 is installed on the upper end of the workbench 1. A punching assembly 7 is set on the upper end of the top frame 6. The punching assembly 7 includes a hydraulic cylinder 71 installed on the upper end of the top frame 6. An arc-shaped seat 72 is connected to the output end of the hydraulic cylinder 71. A punching die 73 is screwed to the lower end of the arc-shaped seat 72. The arc-shaped seat 72 and the punching die 73 are driven to move down through the output end of the hydraulic cylinder 71, and the punching die 73 performs punching operations on the steel pipe.

[0034] Working principle: This utility model is controlled by an external control switch connected to the translation cylinder 39, the first lifting cylinder 42, the second lifting cylinder 51, the hydraulic cylinder 71, and the servo motor 91. In use, one end of the steel pipe is inserted into the inner cavity of the fixed sleeve 36, and then the translation cylinder 39 is opened. The output end of the translation cylinder 39 is inserted into the slot 345 on the outside of the movable plate 344, which then moves the movable plate 344 towards the sealing plate 342. This, in turn, causes the first connecting piece 346 on the outside of the movable plate 344 to drive the movable rod 347 connected to it. One end moves upward, causing the first connecting piece 346 on the outer side of the sealing disc 342 to move one end of the movable rod 347 connected to it simultaneously upward. This, in turn, causes the two sets of movable rods 347 to move the second connecting piece 348 and its upper arc-shaped plate 349, which are rotatably connected to it, upward. Thus, the three sets of arc-shaped plates 349 support and clamp the inner cavity of the steel pipe, facilitating the support and clamping of steel pipes with different inner diameters, effectively improving practicality. Furthermore, depending on the size of the steel pipe, the output end of the second lifting cylinder 51 drives the V-shaped plate 52 to move up and down until it is in contact with the outer surface of the steel pipe. The surfaces are in close contact, which facilitates stable support for the steel pipe, allowing for stable movement, rotation, and punching operations. Then, the output of the servo motor 91 drives the lead screw 92 to rotate, while the threaded block 94 on the outside of the lead screw 92 moves left and right. Simultaneously, the threaded block 94 drives the support rod 95 through the first movable groove 10, moving the fixed seat 31 and the entire clamping mechanism 3 to below the punching assembly 7. The output of the hydraulic cylinder 71 then drives the arc-shaped seat 72 and the punching die 73 to move downwards, and the punching die 73 punches the steel pipe. In the punching operation, when the steel pipe needs to be rotated and adjusted, the output end of the first lifting cylinder 42 drives the support plate 43 to move up and down. The limiting post 46 at the upper end of the support plate 43 passes through the L-shaped plate 41 to limit and stabilize its movement. When the rack 44 at the lower end of the support plate 43 moves up and down, it drives the meshing gear ring 45 and the fixing sleeve 36 to rotate. The fixing sleeve 36 drives the entire clamping assembly 34 and the steel pipe to rotate through the connecting rod 35, so that the side of the steel pipe that needs to be punched can be rotated and adjusted to be directly below the punching assembly 7, which is convenient for punching operations.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
