In progressive die except pure stamping-out be stamped into plane machining except, the product with stamping-out, flange, bending, molding or stretching is tridimensional stamping processing form.Therefore, need in progressive die to arrange material guide mechanism, with the continuous cutting of material, stamping-out, molding process in ensure, with the material unimpeded feeding in mould, often to complete a jig frequency, must float off, with material, the height dimension that die plane is certain.Fig. 1 is the material guide mechanism operation principle schematic diagram of prior art progressive die, and guide post 1 is inserted in the through hole of die 3 and the groove of die bottom plate 4, and spring 2 is between guide post 1 and die bottom plate 4；The end of guide post 1 is provided with gathering sill, the to be processed gathering sill being positioned at guide post 1 with material 8, floats off above die 3 so that feeder push belt material 8 before processing under the effect of guide post 1 with material 8；Adding man-hour, guide post 1 is pressed into the inside of die 3 by stripper 6, is fitted in the surface of die 3 with material 8, punch 7 complete punch process.
In order to band material 8 can move smoothly in gathering sill, with leaving certain gap between material 8 and gathering sill, this gap makes to swing in the process being continuously fed to material 8, affects the precision of stamped part.
Utility model content
The technical problems to be solved in the utility model is: the problem that with material material guide mechanism in swing operationally internal in order to solve progressive die, and this utility model provides a kind of guide post with depth gradual change gathering sill to solve the problems referred to above.
This utility model solves its technical problem and be the technical scheme is that the material guide device of a kind of progressive die, including guide post, die and die bottom plate, the top of guide post is provided with gathering sill, bottom is provided with positive stop lug boss, described die offers through hole, described guide post is located in the through hole of die and can along the axially-movable of through hole, described die bottom plate offers groove, the positive stop lug boss of guide post is positioned at the groove of die bottom plate, it is provided with spring between guide post and die bottom plate, described gathering sill is the groove of the depth gradual change along guide post circumference, described material guide device also includes stirring parts, described parts of stirring can stir the rotation of guide post.
A kind of preferred, described in stir parts be the circular shifting block being arranged in stripper, described shifting block can be connected with guide post and drive guide post to rotate.
Another kind of preferred, described in stir parts and can also is that the helicoid being arranged in die bottom plate groove is protruding, the end face of the positive stop lug boss of described guide post is provided with corresponding helicoid breach protruding with the helicoid in die bottom plate groove.
Owing to the gathering sill of this utility model guide post is the groove of a kind of depth gradual change, after guide post rotates, no longer existing with the gap between material and gathering sill, the position with material can be accurately controlled.
The beneficial effects of the utility model are, the constant depth of traditional direction groove is changed to the degree of depth of depth gradual change by this utility model, by rotating guide post, and the bottom of gathering sill and be change with the gap length between material；When needs push belt material, rotate guide post and make the bottom of gathering sill and maximum with the gap between material；After push belt material action completes, again rotate guide post and make the bottom of gathering sill contact to be accurately positioned band material with band material, improve the quality of stamped part.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
(embodiment 1)
Such as Fig. 2, shown in Fig. 4 and Fig. 5, the material guide device of a kind of progressive die described in the present embodiment, including guide post 1, die 3 and die bottom plate 4, the top of guide post 1 is provided with gathering sill 11, bottom is provided with positive stop lug boss 12, described die 3 vertically offers through hole, described guide post 1 is located in the through hole of die 3 and can along the axially-movable of through hole, described die bottom plate 4 offers groove, the positive stop lug boss 12 of guide post 1 is positioned at the groove of die bottom plate 4, spring 2 it is provided with between guide post 1 and die bottom plate 4, described gathering sill 11 is the groove of the depth gradual change along guide post 1 circumference, described material guide device also includes stirring parts, described parts of stirring can be stirred guide post 1 and rotate.Described parts of stirring are the circular shifting block 5 being arranged in stripper 6, and described shifting block 5 can be connected with guide post 1 and drive guide post 1 to rotate.
The gathering sill 11 of the present embodiment is a groove along the depth gradual change of guide post 1 circumference；The bottom of gathering sill 11 and changing along with the rotation of guide post 1 with the gap between material 8 edge.
It is positioned at the gathering sill of guide post 1 with material 8, floats off above die 3 with material 8 so that feeder push belt material 8 before processing under the effect of guide post 1.Progressive die is adding man-hour, and guide post 1 is pressed into the inside of die 3 by stripper 6, is fitted in the surface of die 3 with material 8, punch 7 complete punch process.
In the stage of push belt material 8, guide post 1, by band material 8 jack-up, floats off on the surface of groove 3 with material 8, and this stage keeps the bottom of gathering sill 11 and maximum with the gap between material 8 edge, facilitates push belt material 8；In the punching press stage, guide post 1 is pressed into the inside of die 3 by stripper 6, being fitted in the surface of die 3 with material 8, utilizing shifting block 5 to drive guide post 1 to rotate the bottom making gathering sill 11 and with material 8 EDGE CONTACT to be accurately positioned the position with material 8, thus improving the dimensional accuracy of stamped part.
(embodiment 2)
In the same manner as in Example 1, the present embodiment rotates the mode of guide post 1 as different from Example 1 for the structure of the present embodiment guide post 1 and mounting means.The present embodiment is provided with the breach 13 of a helicoid in the bottom of the positive stop lug boss 2 of guide post 1, and position corresponding in the groove of die bottom plate 4 is provided with a helicoid projection 9；When guide post 1 is pressed into the inside of die 3 by stripper 6, the helicoid breach 13 of guide post 1 and the helicoid projection 9 of die bottom plate 4 are fitted completely, now should ensure that the bottom of gathering sill 11 and the laminating of band material 8 edge.In the stage of push belt material 8, guide post 1, by band material 8 jack-up, floats off on the surface of groove 3 with material 8, and the band material 8 that the machine that is fed promotes relies on frictional force to drive guide post 1 to rotate to an angle, with automatically obtaining suitable gap between material 8 and gathering sill 11.
Be can be seen that by above example, this utility model is the degree of depth that the constant depth of traditional direction groove 11 changes to depth gradual change, the bottom of gathering sill 11 is controlled and with the gap length between material afterwards by rotation guide post 1, make lead 1 possess two kinds of functions of guide and location, improve the dimensional accuracy of progressive die stamped part.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, it is necessary to determine its technical scope according to right.
