[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Embodiment 1:

[0025] Please refer to Figures 1-4 The utility model provides a kind of special-shaped steel pipe forming die of convenient replacement, including operation table 1, the front and rear ends of operation table 1 are respectively provided with positioning assembly 2 and fixed assembly 3, fixed assembly 3 includes fixed seat 35, fixed groove 351 is opened on fixed seat 35, template 5 is inserted in fixed groove 351, the both sides of fixed seat 35 are fixedly provided with slide rod 31, the slide rod 31 of the both sides of fixed seat 35 is slidably installed with moving seat 33, the moving seat 33 of the both sides of fixed seat 35 is provided with fixed frame 34 symmetrical to each other, fixed cavity 341 is opened on the inner side of fixed frame 34, fixed cavity 341 is adapted to the side wall of template 5, bidirectional threaded rod 32 is rotatably installed in fixed seat 35, the screw of the both ends of bidirectional threaded rod 32 is respectively connected with the moving seat 33 of the both sides of fixed seat 35, and one end of bidirectional threaded rod 32 is provided with drive assembly 4;

[0026] Drive assembly 4 includes worm gear 42, worm gear 42 is fixedly connected with bidirectional threaded rod 32, worm gear 42 is engaged with worm 41, worm 41 is rotatably installed on operation table 1, and the top end of worm 41 is provided with handle 43.

[0027] Specifically, the operator rotates the handle 43 to drive the worm 41 to rotate. Since the worm 41 is engaged with the worm gear 42, the rotation of the worm 41 drives the worm gear 42 to rotate. Since the worm gear 42 is fixedly connected with the bidirectional threaded rod 32, the rotation of the worm gear 42 drives the bidirectional threaded rod 32 to rotate. The two ends of the bidirectional threaded rod 32 are screwed with the moving seats 33 on the two sides of the fixed seat 35, respectively. The rotation of the bidirectional threaded rod 32 drives the moving seats 33 on the two sides to move along the slide rod 31 to the two sides, thereby driving the fixed frame 34 to move synchronously, so that the fixed cavity 341 on the inner side of the fixed frame 34 is separated from the template 5, and the fixing of the template 5 is released.

[0028] At this time, the template 5 in the fixed groove 351 can be taken out, and then a new template 5 is inserted into the fixed groove 351. The handle 43 is rotated in the reverse direction, so that the moving seat 33 drives the fixed frame 34 to move in the reverse direction. The fixed cavity 341 of the fixed frame 34 clamps the side wall of the new template 5, and the fixing of the new template 5 is completed.

[0029] Through the simple operation of rotating the handle 43, the opening and closing of the fixed frame 34 can be realized, without the need for complex tools and cumbersome operation steps, thereby reducing the labor intensity and operation difficulty of the operator. The transmission of the worm gear 42 and the worm 41 has good self-locking property. When the template 5 is fixed, even if it is subjected to external vibration or other external force, the worm 41 will not easily rotate, thereby ensuring the position fixing of the bidirectional threaded rod 32. At the same time, the worm 41 and the operation table 1 are connected in a damping rotary connection, which can avoid the deflection of the worm 41 due to vibration and other reasons, so that the fixed frame 34 can continuously and stably fix the template 5 in the fixed groove 351, thereby ensuring the stability and reliability of the mold during use.

[0030] Further, in order to protect the stability of the steel pipe, please refer to Figures 1-4 The positioning assembly 2 comprises a support 21, an upper support plate 27 and a lower support plate 23 which are slidably installed on the support 21, the lower support plate 23 is connected with the output end of the electric telescopic rod 22, the upper support plate 27 and the lower support plate 23 are provided with mutually symmetrical positioning frames 24, the top of the upper support plate 27 is rotatably installed with a screw rod 26, and the screw rod 26 is rotatably connected with the support 21.

[0031] The positioning frame 24 is provided with a positioning groove which is in a V shape.

[0032] The positioning groove of the positioning frame 24 is rotatably installed with a rotating roller 25.

[0033] Specifically, the lower support plate 23 can be pushed to slide on the support 21 by the electric telescopic rod 22, so that the position of the steel pipe can be flexibly adjusted according to the diameter of the steel pipe, and the steel pipe is on the same axis as the mold plate 5. The upper support plate 27 can be driven to slide on the support 21 by rotating the screw rod 26, so that the distance between the upper support plate 27 and the lower support plate 23 can be flexibly adjusted, and the two positioning frames 24 can be tightly attached to the outer surface of the steel pipe, so that the steel pipe can be preliminarily positioned and fixed.

[0034] The V-shaped positioning groove on the positioning frame 24 can be well attached to the circular outer surface of the steel pipe. Regardless of the diameter of the steel pipe, the V-shaped positioning groove can form a line contact with the surface of the steel pipe within a certain range, thereby providing stable support and positioning, and limiting the movement of the steel pipe.

[0035] The rotating roller 25 installed in the positioning groove of the positioning frame 24 will be in contact with the surface of the steel pipe when the steel pipe is placed in the positioning groove. When the steel pipe needs to move during processing, the rotating roller 25 can rotate to reduce the friction between the steel pipe and the positioning groove, avoid scratching the surface of the steel pipe, and ensure the mobility of the steel pipe. At the same time, it can better adapt to the movement of the steel pipe, further ensuring the stability of the steel pipe during processing.

[0036] Working principle: rotate the handle 43 to drive the worm 41 to rotate, the worm 41 drives the worm gear 42 to rotate, and then the bidirectional threaded rod 32 rotates, the moving seat 33 on both sides moves along the slide rod 31 to both sides, drives the fixed frame 34 to move synchronously, the fixed cavity 341 is separated from the original mold plate 5, the old mold plate 5 is taken out, according to the specifications of the special-shaped steel pipe to be processed, the appropriate mold plate 5 is selected and placed in the fixed groove 351 of the fixed seat 35, then the handle 43 is reversely rotated, the moving seat 33 drives the fixed frame 34 to move reversely, the fixed cavity 341 clamps the side wall of the new mold plate 5, and the mold plate 5 replacement is completed.

[0037] Start the electric telescopic rod 22 to push the lower support plate 23 to slide on the support 21, adjust the position of the steel pipe according to the diameter of the steel pipe, and make the steel pipe on the same axis as the mold plate 5. Rotate the screw rod 26 to drive the upper support plate 27 to slide on the support 21, adjust the distance between the upper support plate 27 and the lower support plate 23, and tightly attach the two positioning frames 24 to the outer surface of the steel pipe, complete the preliminary positioning and fixing of the steel pipe.

[0038] Start the related steel pipe forming equipment to process the positioned steel pipe. During processing, the steel pipe will move, the rotating roller 25 in the positioning groove of the positioning frame 24 will rotate, reducing the friction between the steel pipe and the positioning groove, ensuring the stable movement of the steel pipe, and enabling it to better cooperate with the mold plate 5 to gradually form a special-shaped steel pipe under the action of the mold plate 5.

For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
