[0011] Further, the positioning pin 3 is radially arranged on the outer wall of the positioning plunger.

[0012] Further, the positioning pin 3 radially penetrates the positioning plunger.

[0013] Further, the front end of the positioning plunger is formed with a cross-shaped protrusion, the protrusion is in shape fit with the cross-shaped cavity, and the height of the protrusion is shorter than the length of the cross-shaped cavity. The tightness and length of the steel wire brush strip are controlled by adjusting the height of the cross-shaped protrusion, so as to ensure that the formed steel wire meets the requirements of the steel wire brush.

[0014] The utility model discloses the advantage is: the utility model discloses when using through the positioning pin adjustment positioning column position, the length of the positioning steel wire is repaired to meet the length and shape of the drawing requirement, ensure that the steel wire after forming can be quickly and accurately put into the steel wire brush and position, can through the spring increase pressure guarantee steel wire in the brush effect after forming, through the shell sliding groove position to control steel wire position size, through the shell end face notch control steel wire overall shape, thereby when adjusting the positioning column, realize length adjustment and appearance control, use steel wire brush position repair edge tool to promote the efficiency of installing steel wire brush, ensure the surface quality of aircraft parts.
