Description

Numerical control punch die combined type drift

Technical field

The utility model relates to the punching machine mold drift, especially the box-like drift of numerical control press small size set of molds.

Background technology

Existing numerical control press small size mold and punching head is holistic drift mostly, and after the cutting edge wearing and tearing of drift bottom, whole Zhi Chongtou scraps and can not use, the drift that need more renew.Because the material of drift is a high-speed tool steel, manufacturing cost is high, thereby causes very big waste.Minority is used knockdown drift, and because of no feather key and cutting edge location structure, so only can be used on the circular cutting edge, the scope of application is little, influences the popularization of combined type drift.

Summary of the invention

The purpose of the utility model provides a kind of low cost of manufacture, and the scope of application is wide, and most of assembly can be reused, and changes the numerical control punch die combined type drift simple to operate towards core.

The technical solution of the utility model is, numerical control punch die combined type drift comprises connecting rod, punch body, towards core, and the top of connecting rod is provided with annular groove or the screw thread that is connected with attacking head, and its underpart is connected with the top of punch body through screw thread; The bottom of punch body is provided with a positioning round orifice coaxial with its external diameter; On the hole wall of positioning round orifice, radially be provided with screw; In this screw, be provided with holding screw, be provided with the positioning cylinder that is connected with the positioning round orifice of punch body bottom, be provided with an annular awl groove at the middle part of this positioning cylinder towards the top of core; The inner end overhead of above-mentioned holding screw in this annular awl groove, thereby make lower position-arresting on the core.

Can be provided with feather key on the face of cylinder of above-described punch body, the hole wall of the positioning round orifice of the bottom of punch body is provided with one or more axial location groove, in the said axial location groove one with punch body on feather key keep same orientation.On the ladder end face vertical of core with positioning cylinder, be provided with the alignment pin vertical with this end face, the axial location groove on the hole wall of the positioning round orifice of this alignment pin and punch body constitutes the location and is connected.

Can be provided with three axial location grooves on the hole wall of the positioning round orifice of the bottom of above-described punch body; In said three axial location grooves one with punch body on feather key keep same orientation, the angle between this axial location groove and other two axial location grooves is respectively 135 ° and 270 °.

The principle of the utility model is with existing numerical control press small size mold integral formula drift, be divided into by function of use the coupling part connecting rod, targeting part punch body and stamping-out part dash core, each several part can be used number of various materials.And the feather key on the punch body with and the lower surface on the setting of a plurality of positioning splines, increased the function that drift blade angle orientation changes, to have satisfied the requirement of the circular and various special-shaped workpieces of stamping-out.

The utility model has the advantages that the use cost that has overcome numerical control press small size mold integral formula drift is high; The defective that function of use is single; The more important thing is has increased the function that drift blade angle orientation changes, can not only stamping-out circular, also can satisfy the requirement of the various special-shaped workpieces of stamping-out; And can conversion the requirement of needed various angle orientations, and change drift dash the simple to operation of core.

Fig. 2 is along the A-A cutaway view among Fig. 1;

Fig. 3 is the stereogram of punch body;

Fig. 4 is the stereogram towards core.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model mainly comprises connecting rod 1, punch body 2 and towards core 6.Wherein connecting rod 1 usefulness structural steel is processed, and the general alloy tool steel of punch body 2 usefulness is processed, and processes towards core 6 usefulness high-speed tool steels.The top of connecting rod 1 is processed with external screw thread, also can be processed with annular groove and be connected with attacking head, and its underpart is processed with external screw thread and is connected with the internal thread of punch body 2 upper ends.Punch body 2 bottoms are processed with coaxial with external diameter and vertical with its end face positioning round orifice 21, on the hole wall of positioning round orifice 21, are processed with the screw that holding screw 4 is installed.On the hole wall of positioning round orifice 21, also be processed with three axial location grooves 22 that are symmetrically distributed with its axis; Wherein reference axial direction locating slot 221 forms 135 ° and 270 ° with other two axial locating slot 222 and 223, and angle can be confirmed by design as required between axial location groove number and groove.The feather key 3 that is in same orientation with reference axial direction locating slot 221 is installed on the external cylindrical surface of punch body 2, can only does stamping-out motion up and down, prevent its rotation to guarantee multipart punch.Top towards core 6 is processed with the positioning cylinder 61 that matches and be connected with the positioning round orifice 21 of punch body 2 bottoms, is processed with annular awl groove 62 at the middle part of this positioning cylinder 61.On the ladder end face vertical with positioning cylinder 61, the alignment pin vertical with this end face 5 is installed, this alignment pin 5 is connected with axial location groove 22 location of punch body 2 bottoms.Bottom towards core 6 is a cutting edge 63, and cutting edge 63 confirms that by design present embodiment is 0 °, but can be transformed to 135 ° or 270 ° with the orientation of alignment pin 5.Positioning cylinder 61 towards core 6 is inserted in the positioning round orifice 21 of punch body 2 bottoms, and its ladder end face rests on punch body 2 lower surfaces, withstands the bottom land of the annular awl groove 62 of positioning cylinder 61 with holding screw 4, makes lower position-arresting on core 6 and the punch body 2.When needs change the orientation towards the cutting edge 63 of core 6; As long as unclamp holding screw 4; Extract towards core 6,, will be inserted into the positioning round orifice 21 interior and fastening holding screws 4 of punch body 2 bottoms again towards the positioning cylinder 61 of core 6 with another axial location groove 222 or 223 that alignment pin 5 alignings need be adjusted.
