Description

Be used for fashioned cold heading mould of limit force pole Technical Field The utility model relates to the technical field of cold heading dies, in particular to a cold heading die for forming a force limiting rod. Background The force limiting rod is under the huge pressure of the safety belt when the vehicle is impacted, the force limiting rod generates torsion deformation to absorb energy, and meanwhile, the safety belt can be continuously released for a plurality of centimeters after being locked, so that the time of acting force applied to a human body by the safety belt is prolonged, the stress applied to the human body is reduced, and the human body can be effectively prevented from being hurt by the safety belt. In the production process of the force limiting rod, the force limiting rod needs to be machined by using cold heading machining equipment, so that a cold heading die is needed. The cold heading die is a die for cutting off a blank on a cold heading machine, preforming the blank, and forming the blank into a cold-formed piece. The existing cold heading mould that is used for limit power pole fashioned mostly is when using, needs to be in cold heading mould internally mounted and accords with the cold heading mould inner core of processing demand, processes limit power pole through cold heading mould inner core, but the current cold heading mould that is used for limit power pole fashioned mostly is when changing the inner core, generally needs to change corresponding extracting tool, changes cold heading mould inner core through the instrument to it is comparatively inconvenient when changing to have led to cold heading mould inner core, make cold heading mould inner core change efficiency reduce, thereby influence the use of cold heading mould. Accordingly, the present utility model provides a cold heading die for forming a force limiting rod to solve the above-mentioned problems.
