Embodiment 1
[0025] Draw a line on the surface of a stainless steel wire with a diameter of φ3.5mm and a length of 300mm.
[0026] First cut 300mm stainless steel wire, refer to the attached Figure 1-8 , put the tip of the line drawing pen 5 inward, put it into the pen hole 9, put the spring 6 into the pen hole 9, and screw in the adjustment screw 7, use the pin shaft 3 to connect the rotating arm 2 with the ear plate 8, and insert the cotter pin 4 Fix, place the wire 10 that needs to be drawn on the inner corner of the main body 1 (that is, the wire positioning groove), turn the rotating arm 2 to press the wire 10, so that the wire 10 is completely attached to the two side walls of the wire positioning groove on the main body 1 Close, adjust the adjustment screw 7, make the pressure between the nib of the line drawing pen 5 and the wire 10 appropriate, press the rotating arm 2 with your hand, and pull the wire 10, so that the nib of the line drawing pen 5 draws an axis on the surface of ...

The invention discloses a simple line drawing device for a wire. The simple line drawing device for the wire comprises a main body, a rotating arm, a line drawing pen and a spring, a wire positioning groove used for containing the wire is formed in the main body, a lug plate is arranged on one side wall of the wire positioning groove, one end of the rotating arm is rotationally connected with the lug plate, therefore, the wire needing to be subjected to line drawing can be pressed at the bottom of the wire positioning groove by rotating the rotating arm, a line drawing pen and the spring are both installed in a pen hole in the bottom of the wire positioning groove of the main body, a pen point of the line drawing pen is opposite to the wire needing to be subjected to line drawing in the wire positioning groove, one end of the spring abuts against the main body, and the other end abuts against the tail end of the line drawing pen. According to the simple line drawing device for the wire, the rotating arm is used for pressing the wire needing to be subjected to line drawing in the wire positioning groove, positioning of the wire is achieved, the pen point of the line drawing pen is in good contact with the wire by utilizing the elastic force of the spring, and an inspector can automatically draw an axial straight line on the surface of the wire only by pulling the wire; and compared with a traditional manual line drawing method, the line drawing difficulty is greatly reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to a simple line drawing device which can quickly draw an axial straight line on the surface of the wire used when performing a torsion test on the wire, and belongs to the technical field of detection equipment. Background technique [0002] Metal wires are widely used in equipment manufacturing, building construction, power transportation and other fields. Since the manufacturing process of transmission wires and steel strands needs to go through the stranding process, there are strict requirements on the torsional performance of the wires. When performing a torsion test on the wire rod, it is necessary to draw an axial straight line on the surface of the wire rod. With the twisting of the wire rod, the drawn straight line will form a spiral line distributed along the axial direction on the wire rod surface. After the wire rod is twisted and broken, according to the spiral line The degree of density and uniformity can intuitive...
