Description
Technical field
The utility model is the wrong shear mould for cold roll forming production line, belongs to the supporting technical field of mold of cold roll forming milling train, particularly the wrong shear mould of a kind of large anterior angle.
Background technology
With the banded section bar of cold roll forming mill milling, to according to requirements, be cut off by different length when producing.Cut-out mode can be divided into two classes substantially, namely has waste material to cut off and no waste mine cut-out.It is all adopt dislocation to cut mutually that no waste mine cuts off mode, namely the method for the die cavity Linear cut of dynamic model, quiet mould is processed into the pattern consistent with workpiece cross section, workpiece is allowed to pass from die cavity, dynamic model translation under the drive of oil cylinder, the die cavity of the die cavity of dynamic model and quiet mould is misplaced, thus cuts off workpiece.
Because the shape of cross section of section bar is complicated, in order to reduce distortion, traditional way is: during cutting on line die cavity, is always cut into by die cavity consistent with workpiece shapes as far as possible, just reserves a small amount of gap.When this just makes mold work, each bar cutting edge almost participates in cutting simultaneously, adds upper impression narrower in width, cannot threading during Linear cut, the rake face of blade inclined plane can not be cut to, namely anterior angle cannot be cut out, 0 ° of anterior angle can only be adopted to cut, so cutting force is very large.Cause blade mould when cutting and cut out workpiece to produce larger vibration and moderate finite deformation occurs thus, each several part intensity and the rigidity of power and mould during Design of Dies, will be increased for this reason.
On the other hand, because the cavity shape of dynamic model is consistent with workpiece cross section, dynamic model is not only cutting edge and absorption surface when moving, but whole rake face is all at extruding workpiece, so increase the deformation of workpiece.
In order to solve the problem, die cavity and the rake face of mould just need otherwise designed, and this is the utility model key problems-solving just.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of and reduces the wrong shear mould of the long large anterior angle of cutting force, reduction workpiece deformation and die life.
The purpose of this utility model is achieved through the following technical solutions: the wrong shear mould of a kind of large anterior angle, it comprises pedestal, quiet mould and dynamic model, described quiet mould is installed in pedestal, the lateral surface of pedestal is provided with a guide rail, dynamic model is arranged in guide rail, described dynamic model upper end be connected with an oil cylinder and under the promotion of oil cylinder dynamic model along guide rail translation, described dynamic model and quiet mould all offer a die cavity, workpiece passes the die cavity of dynamic model and quiet mould simultaneously, the die cavity upper surface of described dynamic model offers the dynamic model rake face of a tilting, make dynamic model have a large anterior angle.
The tilt angle alpha of described dynamic model rake face is 10 ° ~ 20 °.
The tilt angle alpha of described dynamic model rake face is 15 °.
The non-blade port limit of described dynamic model and the quiet mould rake face of quiet mould form a sedimentation step, and the width of the die cavity of dynamic model is increased.
The utility model has the following advantages: wrong shear mould of the present utility model, increase the width of the die cavity of dynamic model, make workpiece more easily by die cavity, simultaneously also for the rake face of Linear cut tilting provides threading position, dynamic model rake face is arranged to tilting, in the process of cutting off, cutting edge portion is only had to extrude workpiece, and dynamic model rake face no longer pushes workpiece, workpiece is cut brisk, thus reduce cutting force, the deformation of reduction workpiece, the vibration reducing mould and distortion, improve the service life of this wrong shear mould.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross-sectional schematic of A-A in Fig. 1;
Fig. 3 is I place enlarged drawing in Fig. 2;
In figure, 1-pedestal, the quiet mould of 2-, 3-dynamic model, 4-workpiece, 5-die cavity, the quiet mould rake face of 6-, 7-dynamic model rake face, 8-guide rail.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, the wrong shear mould of a kind of large anterior angle, it comprises pedestal 1, quiet mould 2 and dynamic model 3, described quiet mould 2 is installed in pedestal 1, the lateral surface of pedestal 1 is provided with a guide rail 8, dynamic model 3 is arranged in guide rail 8, described dynamic model 3 upper end be connected with an oil cylinder and under the promotion of oil cylinder dynamic model 3 along guide rail 8 translation, described dynamic model 3 all offers a die cavity 5 with quiet mould 2, workpiece 4 passes the die cavity 5 of dynamic model 3 and quiet mould 2 simultaneously, when dynamic model 3 misplaces with quiet mould, cut off workpiece 4, die cavity 5 upper surface of described dynamic model 3 offers the dynamic model rake face 7 of a tilting, dynamic model 3 is made to have a large anterior angle, in the present embodiment, as shown in Figure 3, the non-blade port limit of described dynamic model 3 and the quiet mould rake face 6 of quiet mould 2 form a sedimentation step, the width of the die cavity 5 of dynamic model 3 is increased, this is not only conducive to workpiece 4 by die cavity 5, also for the rake face of Linear cut tilting provides threading position, cutting for moulding material can record, anterior angle often increases 1 °, cutting force can reduce 2% ~ 3%, in the present embodiment, the tilt angle alpha of described dynamic model rake face 7 is 10 ° ~ 20 °, the tilt angle alpha of preferred dynamic model rake face 7 is 15 °, and the die cavity 5 of quiet mould 2 not only has cutting function in the present embodiment, also has the positioning function to workpiece 4 simultaneously, and the quiet mould rake face 6 of quiet mould 2 can not extrude workpiece makes it be out of shape, therefore in the present embodiment quiet mould rake face 6 anterior angle angle be 0 degree.
The course of work of the present utility model is as follows: oil cylinder pushing dynamic model is along guide rail translation, dynamic model misplaces with quiet mould in translation process, thus cut off workpiece 4, in the process of cutting off, only have cutting edge portion to extrude workpiece 4, dynamic model rake face substantially no longer pushes workpiece 4, makes cutting brisk, thus reduce cutting force, the deformation of reduction workpiece 4, the vibration reducing mould and distortion, improve the mold use life-span.
