Description

Technical Field

[0001] This utility model relates to the field of seamless elbow technology, and in particular to a seamless stamping elbow mold. Background Technology

[0002] Seamless elbows are pipe fittings used at pipe bends. They account for the largest proportion of all pipe fittings used in piping systems. Generally, different forming processes are selected for elbows of different materials or wall thicknesses. Common forming processes for seamless elbows used by manufacturers include hot pushing, stamping, and extrusion. When stamping seamless elbows, elbow dies are required for processing.

[0003] In the existing processing, the pipe needs to be clamped and fixed on both sides before the stamping process. This causes deformation to easily occur between the stamping point and the clamping point during the actual processing, making the processed parts unable to meet normal working requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a seamless stamping elbow mold in order to solve the technical problems mentioned in the background art.

[0015] As a further description of the above technical solution:

[0016] The base has a groove for accommodating the sliding of the slide plate, and the width of the T-shaped groove is greater than the width of the groove.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a seamless stamping elbow mold, including a base 3, columns 2 fixedly connected to the top perimeter of the base 3, a top plate 1 fixedly connected to the top of the columns 2, a hydraulic rod 4 fixedly installed on the top plate 1, an arc-shaped plate 5 fixedly connected to the end of the hydraulic rod 4, a groove 301 for accommodating sliding plates 8 on the base 3, sliding plates 8 slidably arranged on both sides of the groove 301, a bidirectional lead screw 15 rotatably installed inside the base 3 through two sets of sliding plates 8, and a second motor 16 fixedly installed on one side inside the base 3. The output shaft of the second motor 16 is fixedly connected to one end of the bidirectional lead screw 15. A first horizontal plate 7 is fixedly connected to the top of the slide plate 8. A threaded sleeve 12 passes through one end of the first horizontal plate 7. The cross-section of the threaded sleeve 12 is elliptical, which restricts the threaded sleeve 12 from rotating with the screw 11. A pressure ring 13 is fixedly connected to the top of the threaded sleeve 12. The screw 11 is screwed into the threaded sleeve 12. A second horizontal plate 9 is fixedly connected to the slide plate 8. A first motor 10 is fixedly installed on the second horizontal plate 9. The output shaft of the first motor 10 is fixedly connected to the bottom end of the screw 11. The second motor 16 drives the bidirectional lead screw 15 to rotate, which, according to the principle of thread transmission, drives the two sliding plates 8 to move closer or further apart, thereby moving the pressure ring 13 and adjusting the distance between the two sets of pressure rings 13. Then, the long tube passes through the pressure ring 13, and the first motor 10 drives the screw 11 to rotate. According to the principle of thread transmission, the screw sleeve 12 drives the pressure ring 13 to move vertically and fix the long tube. Then, the hydraulic rod 4 drives the arc plate 5 to press down and perform a bending operation on the long tube. The simple locking and fixing operation of the pressure ring 13 can prevent deformation in other positions during the processing and improve the processing effect.

[0028] Specifically, such as Figure 2-4As shown, a fixing plate 6 is fixedly connected to both sides of the base 3. The fixing plate 6 has a T-shaped groove 601 that accommodates the slide plate 8 and the two sets of horizontal plates. The width of the T-shaped groove 601 is greater than the width of the slide groove 301, so that the movement of the slide plate 8 and the two sets of horizontal plates is unrestricted. A support block 14 is fixedly connected to the top of the fixing plate 6. An arc groove is provided on the support block 14. The arc groove on the support block 14 supports both ends of the long tube. The inner diameter of the pressure ring 13 is greater than the radial dimension of the arc groove, which facilitates the vertical movement of the pressure ring 13 to lock and fix the long tube.

[0029] Working principle: During use, the second motor 16 drives the bidirectional lead screw 15 to rotate. According to the principle of thread transmission, the two sliding plates 8 move closer or further apart, thereby moving the pressure ring 13 and adjusting the distance between the two sets of pressure rings 13. Then, the long tube passes through the pressure ring 13, and the first motor 10 drives the screw 11 to rotate. According to the principle of thread transmission, the screw sleeve 12 drives the pressure ring 13 to move vertically and fix the long tube. Then, the hydraulic rod 4 drives the arc plate 5 to press down, performing a bending operation on a local part of the long tube. The simple locking and fixing operation of the pressure ring 13 can prevent deformation in other parts during processing and improve the processing effect.
