[0048] like Figure 7 and Figure 8 As shown, the limiting device 7 includes a fixing frame 701, the bottom surfaces of both ends of the fixing frame 701 are fixedly connected to the surface of the bottom plate 1, the inner wall of the fixing frame 701 is rotatably connected to a rotating plate 703, the upper end of the rotating plate 703 is fixedly connected to a connecting block 705, and auxiliary grooves 713 are provided on both side surfaces of the connecting block 705. The inner walls of the two auxiliary grooves 713 are slidably connected to the same slide plate 712, and a screw rod 711 is threaded through the surface of one side of the slide plate 712. One end of the screw rod 711 abuts against the inner wall of the auxiliary groove 713, and the upper end of the slide plate 712 is fixedly connected to a connecting ring 706. The cross section of the connecting ring 706 is "C"-shaped. The connecting ring 706 is an elastic ring. A sliding frame 704 is fixedly connected to one side of the fixed frame 701. A sliding rod 708 is slidably connected to the inner wall of the sliding frame 704. One end of the sliding rod 708 is fixedly connected to the side wall of the rotating plate 703. An extrusion ring 709 is threadedly connected to the arc surface of one end of the sliding rod 708. A protective ring 710 is sleeved on the arc surface of the sliding rod 708. Both ends of the inner wall of the fixed frame 701 are sleeved with a coil spring 702. The two ends of the coil spring 702 are respectively connected to the fixed frame 701 and the rotating plate 703. The inner wall of the connecting ring 706 is fixedly connected to a plurality of pulley frames 707. The plurality of pulley frames 707 are evenly distributed on the inner wall surface of the connecting ring 706.

[0049] The effect achieved by the entire limiting device 7 is that, during the process of extruding and shaping the cable, the position between the connecting block 705 and the connecting ring 706 can be driven to rotate by means of the rotating plate 703 on the surface of the bottom plate 1, and the cable and the connecting ring 706 can be docked, so that the position of the cable can be guided and limited when it is stretched and moved.

[0050] like Figure 9 and Figure 10As shown, the auxiliary device 8 includes a plurality of connecting holes 83, and the plurality of connecting holes 83 are respectively opened on the two side surfaces of the fixed frame 2 and the mounting frame 3, and the plurality of connecting holes 83 are grouped in pairs. The inner wall of each group of connecting holes 83 is slidably penetrated by the same insertion rod 85, and the cross-section of the insertion rod 85 is "T"-shaped. The inner wall of the upper end of the insertion rod 85 is threadedly connected to the positioning shaft 84, and the arc surfaces of the two insertion rods 85 are slidably penetrated by the same connecting plate 82.

[0051] The effect achieved by the entire auxiliary device 8 is that when the entire extrusion molding equipment is used for a long time, in order to facilitate the replacement operation of the first round roller 4 and the second round roller 5, the rods 85 on both sides of the fixed frame 2 and the installation frame 3 are plugged into the connecting holes 83, and the inlay grooves 86 opened on the surface of the inlay frame 81 and the connecting plate 82 are used for plug-in limit protection, so as to facilitate better disassembly and replacement of the fixed frame 2 and the installation frame 3.

[0052] Its overall working principle is that when the cable is produced, an extrusion shaping device is used to extrude its cross section into a specific shape. At this time, the cable will be extruded and shaped by the first round roller 4 and the second round roller 5 between the installation frame 3 and the fixed frame 2. The rotating ring 611 and the driving shaft 614 rotating in the first round roller 4 and the second round roller 5 are moved relative to each other. With the help of the convenient operation of the adjustment device 6, the length of the driving shaft 614 is limited and adjusted, and the entire cable is effectively stretched and shaped. The fixed gear ring 602 and the rotating gear ring 601 at both ends of the rotating roller 9 are used to clamp the cable. During the limit connection, the fixed gear rings 602 on both sides of the rotating roller 9 are slid along the movable groove 604, so that the fixed gear rings 602 are docked with the rotating gear rings 601 on one side of the mounting frame 3, and the movable block 603 is engaged with the movable groove 604, and then the fixed ring 606 is fixed by threaded docking, so as to effectively facilitate the disassembly and replacement of the entire rotating roller 9. At the same time, the rotating rings 611 in the first round roller 4 and the second round roller 5 are threadedly docked and moved with the drive shaft 614, so that the entire extrusion shaping equipment can be better adjusted according to the size of the cable.

[0053] During the process of stretching, extruding and shaping the cable, in order to effectively and conveniently guide and limit the position of the entire cable, the connecting ring 706 on the surface of the base plate 1 is used for assistance. The fixed frame 701 of the base plate 1 drives the rotating plate 703 and the connecting block 705 to deflect their positions. At the same time, the sliding rod 708 on one side of the rotating plate 703 is used to slide along the sliding frame 704, and the connecting ring 706 sliding on the surface of the entire connecting block 705 is regulated by the sliding plate 712, and the cable is placed in the connecting ring 706 for effective and convenient stretching limit protection operation.
