DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0020] See also Figure 1-5The utility model provides an embodiment: a manufacturing device for a high-voltage cable terminal head, comprising a base 1 and double-layered aisles 2 symmetrically installed on both sides of the top of the base 1, a double-line rolling mechanism 4 for transferring high-voltage cables is installed between the two double-layered aisles 2, a middle vertical plate 5 is installed on the top of the two double-layered aisles 2, an E-shaped frame 6 is fixed on the outer wall of one side of the middle vertical plate 5, and upper pressure cable parts 7 are slidably installed on both sides of the inside of the E-shaped frame 6, an inner U-shaped arm 9 is installed on the back of the two upper pressure cable parts 7, and a double-axis cylinder 8 for driving the inner U-shaped arm 9 to lift and lower is installed on the outer wall of the other side of the middle vertical plate 5;

[0021] A double-station cutting mechanism is provided on the outer wall of the middle vertical plate 5 on one side of the inner U-shaped arm 9. The double-station cutting mechanism is used to cut the surface layer of two high-voltage cables. A PLC control panel 3 is installed on one side of the surface of one of the double-layered aisles 2. The output end of the PLC control panel 3 is electrically connected to the double-line rolling mechanism 4, the double-axis cylinder 8, and the input end of the double-station cutting mechanism.

[0022] A guide plate 202 is fixed at one end of the double-layer aisle 2, and a plurality of lower support wheels 201 are rotatably installed at equal intervals inside the double-layer aisle 2. When the cable is placed on the double-line rolling mechanism 4, the guide plate 202 guides and limits the movement of the cable, and the lower support wheels 201 support and straighten the cable body to ensure that the cable is stably transported and advanced by the double-line rolling mechanism 4.

[0023] The upper pressure cable member 7 includes a right-angle seat 701 slidably mounted on the two inner walls of the E-shaped frame 6, and a connecting beam 702 mounted on the top of the two right-angle seats 701, and an upper support wheel 704 is rotatably mounted between the two right-angle seats 701;

[0024] A slide 703 is fixed on the outer wall of one side of the right-angle seat 701. The slide 703 and the inner wall of the E-shaped frame 6 are slidably matched. The inner U-shaped arm 9, the connecting beam 702 and the right-angle seat 701 are driven downward by the double-axis cylinder 8 until the upper support wheel 704 is pressed on the upper surface of the cable. In this process, the right-angle seat 701 slides relative to the inner wall of the E-shaped frame 6 through the slide 703, so that the upper support wheel 704 applies downward pressure to the cable to ensure stable transportation of the cable.

[0025] The double-line rolling mechanism 4 includes a motor seat 401 installed on the outer wall of one side of the double-layer aisle 2, and a transmission shaft 403 rotatably installed inside the motor seat 401, one end of the transmission shaft 403 passes through the outside of the other double-layer aisle 2, and lower conveying wheels 404 are fixed on both ends of the surface of the transmission shaft 403. A stepper motor 402 for driving the transmission shaft 403 to rotate is installed on the outer wall of one side of the motor seat 401. The rotary power of the stepper motor 402 is transmitted to the transmission shaft 403, and the transmission shaft 403 drives the lower conveying wheel 404 to rotate. Since the cable is pressed by the upper support wheel 704, the lower conveying wheel 404 can actively drive the cable to move forward;

[0026] The double-station cutting mechanism includes a cylinder 12 installed on the outer wall of one side of the central vertical plate 5, and an outer U-shaped arm 10 installed on the top of the piston rod of the cylinder 12. The outer U-shaped arm 10 and the inner U-shaped arm 9 are both made of aluminum alloy components. Cutters 11 are fixed on both sides of the bottom of the outer U-shaped arm 10. The two outer walls of the central vertical plate 5 and the two inner walls of the outer U-shaped arm 10 are slidably matched. When adjusting the cutting depth of the cable skin, the cylinder 12 is turned on through the PLC control panel 3, and the cylinder 12 pulls the outer U-shaped arm 10 and the cutter 11 downward until the blade of the cutter 11 enters the cable. In the process of active movement of the cable, the skin of the cable will be broken. The synchronous cutting structure of the double cable workpiece can reduce the monotonous and repetitive labor of the operator.

[0027] When the embodiment of the present application is in use, the staff first places the two cables whose surface cortexes are to be broken in the double-layer clamp 2, and makes the cables pass through the double-line rolling mechanism 4 and the upper cable pressing member 7. At this time, the staff turns on the double-station cutting mechanism through the PLC control panel 3 to work, adjusts the cutting depth of the double-station cutting mechanism on the cable, so that the cutting piece of the double-station cutting mechanism initially breaks the cable. Then, the staff turns on the double-line rolling mechanism 4 and the double-axis cylinder 8 through the PLC control panel 3 to work, and the double-axis cylinder 8 drives The inner U-arm 9 and the upper cable pressure member 7 move downward until the upper cable pressure member 7 applies downward pressure to the cable line, and the double-line rolling mechanism 4 stably conveys the two cable lines forward. At this time, since the double-station cutting mechanism is fixed, the skin of the cable line is cut, and the device realizes the synchronous cutting function of the double cable workpiece, and can complete the skin cutting operation of two cables at one time, saving time and labor costs. The double-station cutting mechanism completes the skin cutting operation of the cable line, which can ensure the accuracy and consistency of the cutting, and reduce the influence of human operation factors on the production quality.
