[0023] As a technical optimization solution of the present invention, by setting up a movable support assembly 8, the support seat 81 can limit the surface movement of the slider 82 through the slide groove 83 during use. After the slider 82 is limited, it can stably drive the bottom movement of the support seat 81 to be limited. During use, the user can fix the support seat 81 on the base 2 to limit the use position of the lower mold 6, thereby enhancing the stability of the movable support during use.

[0024] refer to Figure 1 A movable rod 9 is provided on the top of the base 2 , and a lower mold middle piece 10 is fixedly connected to the top of the movable rod 9 .

[0025] As a technical optimization solution of the present invention, by setting a movable rod 9 and a lower mold middle piece 10, the movable rod 9 can drive the lower mold middle piece 10 to be installed movably during use, so that the lower mold middle piece 10 can limit the bottom of the inner side of the lower mold 6 during use, so that after the upper mold 4 stably pushes the round tube, the lower mold middle piece 10 and the lower mold 6 can cooperate to plastically support and position the round tube.

[0026] refer to Figure 1 The top of the base 2 is provided with a movable groove 11, and four groups of movable grooves 11 are provided, and the four groups of movable grooves 11 are arranged at equal distances. The surface of the movable rod 9 is movably installed with the interior of the movable groove 11.

[0027] As a technical optimization solution of the present invention, by setting a movable groove 11, the movable groove 11 can limit the surface activity of the movable rod 9, which can facilitate the installation and fixation of the connecting rod during use, enhance the convenience of installation and fixation of the connecting rod during use, and avoid situations where it is inconvenient to fix it safely during use.

[0028] refer to Figure 1 The inner side of the support seat 81 is fixedly connected to the limit rod 12, the inner side of the upper mold 4 is provided with a mounting groove 13, and the outer side of the surface of the connecting block 3 is fixed to the inner wall of the mounting groove 13.

[0029] As a technical optimization solution of the present invention, by setting a limit rod 12 and a mounting groove 13, the limit rod 12 can enhance the stability of the support seat 81 during use, and at the same time can limit the bottom activity of the outer side of the lower mold 6 to avoid excessive movement of the lower mold 6 during resetting, which is inconvenient to cooperate with the upper mold 4 to process the round tube.

[0030] refer to Figure 1 A semicircular support groove 14 is provided on the top of the lower mold intermediate member 10, and the bottom of the upper mold 4 is arranged in an arc shape.

[0031] As a technical optimization solution of the present invention, by setting a semicircular support groove 14 and an upper mold 4, the semicircular support groove 14 can limit the surface of the processed round tube during use, so that the round tube can be stably limited and processed during use. The bottom of the upper mold 4 is set in an arc shape, which can effectively process the round tube during use and make the round tube be processed into a suitable arc shape.

[0032] refer to Figure 1 The top of the lower die 6 is arranged in an arc shape, and a fixing groove 15 is provided on the outer side of the slider 82 .

[0033] As a technical optimization solution of the present invention, by setting the lower mold 6 and the fixing groove 15, the top of the lower mold 6 is set in an arc shape, which can effectively cooperate with the push and pressure of the upper mold 4 to limit the bending of the round tube, thereby enhancing the processing stability of the round tube during use. The fixing groove 15 can facilitate the installation and fixation of the slider 82 during use, thereby enhancing the convenience of fixation during use.

[0034] The working principle and use process of the utility model are as follows: when using, first install the die handle 1 into the fixing hole of the upper die 4 of the punch press, fix the base 2 of the lower die 6 on the tooling table of the punch press with screws, then adjust the distance between the two lower die 6 support seats 81, adjust the centering of the upper die 4 and the lower die 6, and then gently close the lower forming die to see if the die is adjusted in place. After the die is adjusted, place the round tube on the lower die 6, and then start the punch press to close the die and form the elbow. During the closing process, the semicircular forming groove 5 of the upper die 4 and the lower die 6, and the semicircular groove in the middle are meshed. The groove 7 and the semicircular support groove 14 protect the round tube from being damaged or flattened. The round tube only needs to be stamped and formed in one process with the cooperation of the upper die 4, the lower die 6 and the lower die middle piece 10, and a straight round tube can be formed to the required effect in one time, which saves working hours and improves the forming efficiency. Since the developed forming die has only one process for forming the bent tube, unlike the hand-wrenching die and the single bend and then stamping forming, there are fewer processes and the probability of quality problems is small, thereby improving the qualified rate of the bent tube, achieving the advantages of reducing the forming process, saving time and improving the forming qualified rate.

[0035] To sum up: this kind of round tube press-bending forming mold, by setting the mold handle 1 to push the connecting block 3 and the upper mold 4, makes the upper mold 4 move to cooperate with the semicircular forming groove 5 to push the round tube that needs to be pressed and pressed under the cooperation of the lower mold 6 and the semicircular meshing groove 7. The movable support component 8 can adjust the use position of the lower mold 6, which solves the problem that most of the existing round tubes need to be pressed and bent step by step during press-bending, which is not only inefficient but also labor-intensive. The consistency of the bent tubes formed by each plate bending is also poor and the quality problems of the bent tubes may easily occur. The use of a rolling machine for forming requires adjustment of the forming parameters so that the rolled bent tubes meet the requirements of the drawings. However, the number of rolling machines is limited and there are certain technical requirements for the machine adjusters, and the round tubes cannot be bent quickly and conveniently to meet the use needs.

[0036] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
