Description

Automatic processing equipment for metal tool parts Technical Field The invention relates to the technical field of automatic processing equipment, in particular to automatic processing equipment for metal tool parts. Background The hexagonal wrench is an indispensable part of metal tool, and current hexagonal wrench automated processing equipment generally includes alignment feeding mechanism, punching press mechanism and shutdown mechanism of bending, and hexagonal steel is sent into after the alignment and is bent the station, bends steel into 90L shape through the cooperation of last stamping workpiece and lower stamping workpiece, in order to improve the convenience that the product used, need carry out chamfering to spanner both ends after bending and accomplish. However, the traditional bending die only relies on the triangle-shaped die cavity to retrain steel, the steel is easy to take place tiny torsion around self axis when receiving bending moment, lead to the spanner angle after the shaping to have the deviation, specifically, when the terrace die pushes down, the steel bears axial compressive force and radial bending force simultaneously, its inside stress distribution along the cross-section is very inhomogeneous, can produce the torsion trend around self axis in the moment that bending moment reaches the peak value, and traditional triangle-shaped die cavity only is point contact or line contact with steel, can only restrict radial movement, can't effectively restrict rotatory degree of freedom, this kind of torsion not only leads to bending point skew, angle deviation, still can produce the surface scratch because of the sharp friction of edge and die cavity, influence product quality. Secondly, the bending and chamfering processes of the wrench are usually performed step by step, and through searching, although the patent with the publication number of CN108747403B integrates chamfering and bending, a multi-station step processing mode is adopted, a workpiece needs to be transferred among stations, the position accuracy of a chamfer surface relative to a wrench body is reduced due to the fact that the standard cannot be completely overlapped with the bending process of the workpiece during secondary clamping, the waiting time caused by station switching also breaks the continuity of production, the auxiliary time is increased, the relative accuracy between the chamfering and bending positions is difficult to ensure, and continuous automatic production with high efficiency and high accuracy cannot be realized.
