Detailed Description

As shown in fig. 1, the wire bending and stripping tool is designed and modified based on a traditional vernier caliper, firstly, a wire stripping knife edge is respectively manufactured into semi-circles which are opposite up and down and have the diameters of 1.6MM, 2.0MM, 2.6MM and 3.2MM, the distance between the circle center and the bottom end of a blade is 5MM, and the stripping function of insulated wires of 1.5MM2, 2.5MM2, 4MM2 and 6MM2 can be realized; cylinders with the diameter of 0.5CM and the height of 1CM are respectively welded at the '0' position (point A, B) of the main ruler and the sliding ruler, and the bending requirement of the lead can be realized by adjusting the measurement and positioning of the sliding ruler according to the actual wiring size; holes with diameters of 4.5mm, 4mm and 3.5mm are respectively arranged at positions 7mm away from the edge of the main ruler head (outer end part) and are collinear in circle center and parallel to the edge of the main ruler head; and the holes are used for bending the wires with different specifications and wire diameters.

When the device is used, firstly, an appropriate wire stripping knife edge diameter is selected according to the section of a wire to strip an insulating layer, after the wire stripping is finished, the size of the required wiring is measured by using a caliper, a sliding ruler is positioned by using a positioning knob (the positioning distance is reduced by 1CM compared with the measuring distance), one end of the stripped wire is fixed at a point A by hand, the other end of the stripped wire is fixed at a point B, meanwhile, the stripped wire slides downwards forcibly along the radian of a cylinder, and after the wires at two ends are bent, the positioning knob is loosened.
