[0025] 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.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a large tapered tube bending die;

[0027] Example 1: In order to adjust the opening size of the tapered lower module 4 and be able to bend products of similar specifications, a lower module 4 is provided on the surface of the lower mold base 1. Fastening bolts 6 pass through both sides of the lower mold base 1. The fastening bolts 6 are threaded through the surface of the lower mold base 1 and connected to nuts 7. A spring 10 is fixedly connected to the bottom end face of the inner groove 8. A pressure plate 9 is fixedly connected to one end of the spring 10. A second guide rod 13 is fixedly installed on the side wall of the pressure plate 9. A first guide rod 11 is fixedly installed on the side wall of the insert 12 at the same horizontal plane as the pressure plate 9. A guide groove 14 is opened on the side wall of the lower mold base 1 at the same horizontal plane as the insert 12.

[0028] The outer wall of the lower mold base 1 has a slot 16, and the fastening bolt 6 passes through the slot 16 and is threadedly connected to the nut 7. The inner groove 8 is opened on the inner surface near the two end faces of the lower mold base 1. The pressure plate 9 and the spring 10 form an elastic component. The insert 12 is in contact with the upper surface of the pressure plate 9 and is slidably connected to the inner groove 8. The pressure plate 9 and the insert 12 are slidably connected on the inner surface of the guide groove 14 through the first guide rod 11 and the second guide rod 13. The inner end face of the guide groove 14 has a clearance groove 15, which is engaged with the first guide rod 11.

[0029] By replacing the traditional multiple sets of lower modules 4 with a single lower module 4, when it is necessary to adjust the opening size of the conical lower module 4, the insert 12 can be ejected from the inner groove 8 between the lower mold base 1 and the lower module 4 through the elastic component composed of the pressure plate 9 and the spring 10 in the inner groove 8. The insert 12 is then firmly fixed between the lower mold base 1 and the lower module 4 by the threaded engagement of the fastening bolt 6 and the nut 7. This allows for adjustment of the opening size of the conical lower module 4, enabling the bending of products of similar specifications. When the insert 12 is not needed, the second guide rod 13 can be pressed down, and the second guide rod 13 slides in the guide groove 14 with the first guide rod 11. The elastic force of the elastic component retracts the insert 12 into the inner groove 8 for storage. When needed, it can be ejected, thus eliminating the need to remove the insert 12, preventing its loss, and improving its applicability.

[0030] Working principle: In actual use, in order to adjust the opening size of the conical lower module 4 and bend products of similar specifications, the traditional multiple sets of lower modules 4 are replaced with a single lower module 4. When it is necessary to adjust the opening size of the conical lower module 4, the insert 12 can be popped out of the inner groove 8 between the lower mold base 1 and the lower module 4 through the elastic component composed of the pressure plate 9 and the spring 10 in the inner groove 8. The insert 12 is then firmly fixed between the lower mold base 1 and the lower module 4 by the threaded engagement of the fastening bolt 6 and the nut 7. Thus, the opening size of the conical lower module 4 can be adjusted, and products of similar specifications can be bent. When the insert 12 is not needed, the second guide rod 13 can be pressed down. The second guide rod 13 slides in the guide groove 14 with the first guide rod 11, and the elastic force of the elastic component retracts the insert 12 into the inner groove 8 for storage. When needed, it can be popped out, so there is no need to remove the insert 12, preventing the insert 12 from being lost and improving its applicability.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
