Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-8 A steel fiber one-step forming machine that is easy to maintain, comprising a workbench 1, a plurality of extrusion heads 2 are evenly arranged on one side of the top of the workbench 1, two guide rollers 3 are vertically arranged on the top of the workbench 1, and a clamping mechanism for clamping the guide rollers 3 is arranged at the bottom of the workbench 1;

[0026] A rectangular limit box 5 is fixed to the other side of the top of the workbench 1, and a vertical cutter 4 is slidably connected inside the rectangular limit box 5. A longitudinal fixing plate 17 is fixed to the top of the vertical cutter 4, and a U-shaped sliding column 6 is arranged outside the longitudinal fixing plate 17. Hydraulic cylinders 16 are evenly fixed to the bottom of the workbench 1 and inside the U-shaped sliding column 6. The output end of the hydraulic cylinder 16 is fixedly connected to the U-shaped sliding column 6, and a fixing mechanism for fixing the longitudinal fixing plate 17 is arranged on the top of the U-shaped sliding column 6;

[0027] A rectangular fixing column 10 is arranged on the outer side of the bottom of the extrusion head 2, a U-shaped limiting ring 11 is arranged on the top of the rectangular fixing column 10, and vertical limiting plates 12 are fixed to both ends of the U-shaped limiting ring 11. The vertical limiting plate 12 is located inside the rectangular fixing column 10 and is slidably connected to the rectangular fixing column 10. The vertical limiting plate 12 is fixed to the rectangular fixing column 10 by bolts. The extrusion head 2 can be fixed by the arrangement of the U-shaped limiting ring 11 and the rectangular fixing column 10.

[0028] Here, by setting the bolts, the vertical limit plate 12 can be moved out of the rectangular fixed column 10, thereby releasing the restriction of the U-shaped limit ring 11 on the extrusion head 2, so that the extrusion head 2 can be disassembled, so as to facilitate the subsequent maintenance and replacement of the extrusion head 2;

[0029] The clamping mechanism includes a U-shaped fixing plate 7, the top of the U-shaped fixing plate 7 is fixedly connected to the workbench 1, one end of the U-shaped fixing plate 7 is bolted to a driving motor 8, the output end of the driving motor 8 is fixed to a first transverse threaded rod 13, the end of the first transverse threaded rod 13 away from the transverse moving column 9 is fixed to a second transverse threaded rod 14, the first transverse threaded rod 13 and the second transverse threaded rod 14 have opposite thread rotation directions, the outer sides of the first transverse threaded rod 13 and the second transverse threaded rod 14 are both threadedly connected to the transverse moving column 9, the outer side of the guide roller 3 is slidably connected to a circular rotating ring 15, the circular rotating ring 15 is located inside the transverse moving column 9 and is rotatably connected to the transverse moving column 9;

[0030] A transverse through groove is provided inside the workbench 1, and the transverse moving column 9 is located inside the transverse through groove and is slidably connected to the workbench 1 through the transverse through groove. The transverse through groove is provided so that the transverse moving column 9 can slide transversely inside the workbench 1;

[0031] A transverse slider is fixed on the outer side of the guide roller 3, and a transverse groove is provided inside the circular rotating ring 15. The guide roller 3 and the circular rotating ring 15 are slidably connected through the cooperation of the transverse slider and the transverse groove. Through the cooperation of the transverse slider and the transverse groove, the circular rotating ring 15 can move transversely on the outer side of the guide roller 3, and then the circular rotating ring 15 can slide out of the outer side of the guide roller 3.

[0032] Here, the operation of the driving motor 8 enables the first transverse threaded rod 13 and the second transverse threaded rod 14 to rotate, and the rotation of the first transverse threaded rod 13 and the second transverse threaded rod 14 enables the transverse moving column 9 to move inside the workbench 1, thereby enabling the spacing between the two transverse moving columns 9 to be adjusted, and the movement of the transverse moving column 9 enables the circular rotating ring 15 to slide on the outside of the guide roller 3, and when the second transverse threaded rod 14 moves out of the outside of the guide roller 3, the guide roller 3 can be disassembled to facilitate the maintenance and replacement of the guide roller 3;

[0033] The fixing mechanism includes a circular pull block 18, a vertical limit rod 19 is fixed to the bottom of the circular pull block 18, a rigid spring 20 is arranged between the circular pull block 18 and the U-shaped sliding column 6 and on the outside of the vertical limit rod 19, a rectangular slot is opened inside the U-shaped sliding column 6, and the longitudinal fixing plate 17 is located inside the rectangular slot and is slidably connected to the rectangular slot;

[0034] A circular through hole is provided inside the longitudinal fixing plate 17, and a vertical limiting rod 19 is located inside the circular through hole and is slidably connected to the longitudinal fixing plate 17 through the circular through hole. When the vertical limiting rod 19 enters the interior of the longitudinal fixing plate 17, it can limit the movement of the longitudinal fixing plate 17 inside the U-shaped sliding column 6;

[0035] Here, when the vertical cutter 4 needs to be disassembled, the circular pull block 18 is pulled in the direction away from the U-shaped sliding column 6. The pulling of the circular pull block 18 enables the vertical limit rod 19 to move out of the interior of the longitudinal fixing plate 17, so that the vertical limit rod 19 releases the restriction on the longitudinal fixing plate 17, so that the vertical cutter 4 can be disassembled.

[0036] Working principle: Through the setting of bolts, the vertical limit plate 12 can be moved out of the rectangular fixed column 10, thereby releasing the restriction of the U-shaped limit ring 11 on the extruder head 2, so that the extruder head 2 can be disassembled, so as to facilitate the subsequent maintenance and replacement of the extruder head 2;

[0037] The operation of the driving motor 8 enables the first transverse threaded rod 13 and the second transverse threaded rod 14 to rotate. The rotation of the first transverse threaded rod 13 and the second transverse threaded rod 14 enables the transverse moving column 9 to move inside the workbench 1, thereby enabling the spacing between the two transverse moving columns 9 to be adjusted. The movement of the transverse moving column 9 enables the circular rotating ring 15 to slide outside the guide roller 3. When the second transverse threaded rod 14 moves out of the outside of the guide roller 3, the guide roller 3 can be disassembled to facilitate the maintenance and replacement of the guide roller 3.

[0038] When the vertical cutter 4 needs to be disassembled, the circular pull block 18 is pulled in the direction away from the U-shaped sliding column 6. The pulling of the circular pull block 18 enables the vertical limit rod 19 to move out of the interior of the longitudinal fixing plate 17, so that the vertical limit rod 19 releases the restriction on the longitudinal fixing plate 17, allowing the vertical cutter 4 to be disassembled.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
