| description | The invention discloses a bending device for a torsion arm at the tail end of a torsion spring. Comprising an upper die, a lower die and a rotating device, the upper die is provided with a male die matched with a torsion spring in a forming mode. An upper die correction groove is formed in the transverse middle of the surface of the male die. The lower die is provided with a female die matched with the torsion spring in forming, and a positioning groove is formed in the transverse middle of the surface of the female die; the rotating device comprises a positioning mandrel, a rotating arm, a fixed shaft and a connecting plate; according to the device, a traditional bending die is optimized, a groove consistent with the axis of a wire is machined in the lower bending die, and the wire is prevented from sliding in the bending and pressing process; by means of the characteristic that a bending material rotates around a bending point in the bending process, a rotatable anti-torsion device is arranged on the bendin |
