Abstract
The invention discloses a blanking die achieving accurate positioning. The blanking die comprises a die shank, an upper die plate, a lower die plate, a punching male die and a trimming male die; guide columns are arranged between the upper die plate and the lower die plate, the die shank is fixedly connected to the upper portion of the upper die plate, and the punching male die and the trimming male die are connected to the lower portion of the upper die plate; a through hole with the shape same as that of a cutting edge of the punching male die is formed in the portion, located on the position perpendicular to the punching male die, of the lower die plate, and a groove with the shape same as that of a cutting edge of the trimming male die is formed in the portion, located on the position perpendicular to the trimming male die, of the lower die plate; limiting columns are further arranged above the lower die plate, limiting blocks are arranged on the upper surface of the lower die plate, the limiting blocks comprise a longitudinal limiting block and transverse limiting blocks, the longitudinal limiting block is located in the front of the feeding direction, and the transverse limiting blocks are located on the side portions of the feeding direction. In general, the blanking die achieving accurate positioning is simple in structure, blanking operation on a sheet metal part is achieved through falling of the upper die plate, the part manufactured through the blanking die is high in accuracy, the machining efficiency is high, and the blanking die is suitable for being applied and promoted.
Description
Technical field
The present invention relates to mould applications, be specially the blanking die of a kind of structure registration simply easy to use.
Background technology
The blanking die of existing registration, generally machinery is all adopted to provide power to carry out resilience, the mode of this reply easily causes damage to the surface of blanking part, affect the quality of product, the blanking die precision of existing registration is lower, because not used for the device of restriction skew between traditional blanking die upper and lower base plate, cause when mould agrees with, produce error, and traditional blanking die there is no billot spacing, when easily causing billot to give, occur that deviation causes wasting material.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the blanking die proposing a kind of registration.
Technical solution of the present invention is achieved in that a kind of blanking die of registration, comprises die shank, cope match-plate pattern, lower bolster, piercing punch, trimming punch; Lead is provided with between described cope match-plate pattern and lower bolster; Described die shank is fixedly connected on the top of cope match-plate pattern; Described piercing punch and trimming punch are connected to the below of cope match-plate pattern; On described lower bolster, the position being positioned at the vertical lower of piercing punch offers and piercing punch cutting edge shape same via, and the position being positioned at the vertical lower of trimming punch offers the groove identical with trimming punch cutting edge shape; The top of described lower bolster is also provided with limited post; The upper surface of described die shoe is provided with limited block; Described limited block comprises longitudinal spacing block and cross spacing block; Described longitudinal spacing block is positioned at the front of feeding direction; Described cross spacing block is positioned at the sidepiece of feeding direction.
Preferably, described lead has 4, is separately positioned on the corner of cope match-plate pattern and lower bolster.
Preferably, described limited post has 2, is separately positioned on the diagonal angle of lower bolster.
Preferably, described cross spacing block has 2, is positioned at the both sides of feeding direction.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The blanking die structure of registration of the present invention is simple, by adding guide post structure, the relative position of upper bolster and die shoe can be limited, make it when agreeing with, skew can not be produced or only produce less skew, effectively can improve the precision of mould like this, improve the quality of product; By adding limited post structure, when upper bolster and die shoe carry out stamping-out, the descending blade excessive wear of crossing position and causing punch end of die shoe can be prevented, is conducive to extending the mold use life-span; By adding upper limit position block in feeding direction front and sidepiece, the accuracy of position when ensureing that billot is given, and then ensure that the reasonable utilization rate of material.Generally speaking, structure of the present invention is simple, and Making mold precision is high, is applicable to promoting the use of.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is the structural representation of another angle of the present invention.
In figure: 1, die shank; 2, cope match-plate pattern; 3, lower bolster; 4, piercing punch; 5, trimming punch; 6, lead; 7, through hole; 8, groove; 9, limited post; 10, longitudinal spacing block; 11, cross spacing block.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The blanking die of registration of the present invention as shown in Figure 1, comprises die shank 1, cope match-plate pattern 2, lower bolster 3, piercing punch 4, trimming punch 5; Lead 6 is provided with between described cope match-plate pattern 2 and lower bolster 3; Described lead 6 has 4, is separately positioned on the corner of cope match-plate pattern 2 and lower bolster 3; Described die shank 1 is fixedly connected on the top of cope match-plate pattern 2; Described piercing punch 4 and trimming punch 5 are connected to the below of cope match-plate pattern 2; On described lower bolster 3, the position being positioned at the vertical lower of piercing punch 4 offers and piercing punch cutting edge shape same via 7, and the position being positioned at the vertical lower of trimming punch 5 offers the groove 8 identical with trimming punch cutting edge shape; The top of described lower bolster 3 is also provided with limited post 9; Described limited post 9 has 2, is separately positioned on the diagonal angle of lower bolster 3; The upper surface of described die shoe 3 is provided with limited block; Described limited block comprises longitudinal spacing block 10 and cross spacing block 11; Described longitudinal spacing block 10 is positioned at the front of feeding direction, for limiting feed extreme position; Described cross spacing block 11 is positioned at the sidepiece of feeding direction; Described cross spacing block 11 has 2, is positioned at the both sides of feeding direction, strictly can control the feeding direction treating stamping-out billot.
The blanking die structure of registration of the present invention is simple, by adding guide post structure, the relative position of upper bolster and die shoe can be limited, make it when agreeing with, skew can not be produced or only produce less skew, effectively can improve the precision of mould like this, improve the quality of product; By adding limited post structure, when upper bolster and die shoe carry out stamping-out, the descending blade excessive wear of crossing position and causing punch end of die shoe can be prevented, is conducive to extending the mold use life-span; By adding upper limit position block in feeding direction front and sidepiece, the accuracy of position when ensureing that billot is given, and then ensure that the reasonable utilization rate of material.Generally speaking, structure of the present invention is simple, and Making mold precision is high, is applicable to promoting the use of.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
