The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] like Figure 5-9 As shown, the present invention provides a tungsten wire rope hot end ball head riveting tool 1, including eight riveting joints 11, each riveting joint 11 has a front end with a 45-degree angle ridge, and a curved riveting groove 111 is formed on the 45-degree angle ridge, and the eight riveting joints 11 are cross-jointed, so that the eight curved riveting grooves 111 are joined to form a circular hole, the diameter of the circular hole is larger than the diameter of the tungsten wire rope 3 but smaller than the outer diameter of the columnar structure of the hot end ball head 4; the length of the circular hole is larger than the length of the columnar structure of the hot end ball head 4, but the length of the columnar structure of the hot end ball head 4 is larger than half of the length of the circular hole; each riveting joint 11 is fan-shaped, so that the eight riveting joints 11 form a circle after riveting.

[0043] Both side surfaces of the arc-surface riveting groove 111 of each riveting head 11 are perpendicular to the arc surface of the arc-surface riveting groove.

[0044] The rear end of the riveting head 11 is provided with a telescopic drive connection hole 113, which is used to connect with a telescopic drive mechanism, so as to drive the riveting head to perform linear telescopic motion. The telescopic drive mechanism usually adopts a cylinder, and other linear drive mechanisms can also be adopted.

[0045] The telescopic drive connection hole 113 is located in the middle of the rear end of the riveting head 11, so that the power of the telescopic drive mechanism can act on the center of the riveting head 11, and the riveting effect is better.

[0046] The side of the rivet head 11 is provided with a screw fixing hole 114 and a positioning hole 115, and the screw fixing hole 114 and the positioning hole 115 are located on the center surface of the rivet head 11. When the rivet head 11 is connected with the slider 21, the slider 21 is positioned with the rivet head 11 through the positioning hole 115, and is connected in the screw fixing hole 114 by screws, so that the slider 21 can be fixedly connected to the rivet head 11.

[0055] Step 4: Start the hot end ball head riveting system to make each riveted head extend and move toward the center at the same time;

[0056] Step 5: Detect the pressure of the riveted joint. When the pressure reaches the preset value, control the tungsten wire rope hot end ball head riveting system to stop; design the preset pressure value so that when the pressure of the riveted joint reaches the preset value, the columnar structure of the hot end ball head shrinks and deforms inwards, and further presses the tungsten wire rope inwards, so that the bonding force between the columnar structure and the tungsten wire rope is stronger;

[0057] Step 6: Control each riveting joint of the tungsten wire rope hot end ball head riveting system to retract to the initial riveting state.

[0058] Before step one, the method also includes cutting the tungsten wire rope and detecting the cut of the tungsten wire rope.
