Abstract

The invention discloses a bending and stamping die. The bending and stamping die comprises an upper die base, an upper padding plate, an upper clamp plate, an upper die plate, a lower die plate, a lower padding plate and a lower die base, wherein a bending punch is fixedly installed at the lower end of the upper die base, the bending punch sequentially passes through the upper padding plate and the upper clamp plate and then is matched with the upper die plate, a bending wall is arranged on one side of the bending punch, an insert core is arranged on the lower die plate, an enter groove is formed in one side of the insert core, the enter groove is aligned at the bending wall, a limiting block is arranged on the lower portion of the insert core, and the limiting block is fixedly installed on the lower die plate through a screw. The bending and stamping die is reasonable in structure and simple to operate, guarantees stability and reliability of bending, uses special structure of the bending punch, reduces bending resistance during the bending process, and reduces failure rate of work pieces, caused by abrasions during the bending process.

Description

A kind of bend punching die
Technical field
The present invention relates to a kind of diel, be specially a kind of bend punching die.
Background technology
Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture.The height of Mould design and manufacturing technical merit, is one of important symbol of a measurement national product manufacture level height, decides the development ability of the quality of product, benefit and new product to a great extent.Bending Mould belongs to the one of diel, is used for the instrument of processing and forming plate, and this instrument has various part to form, and different moulds is made up of different parts.It realizes the processing of article profile mainly through the change of institute's moulding material physical state.The instrument of the product of given shape and size is had in order to make blank become under the effect of bending pressure.
Bending Mould under prior art, most employing cylindrical punch punching press metal plate material also makes its bent for shaping by the extruding of drift outer wall, in the process of punching press, because drift lateral wall and absorption surface area larger, therefore there is larger bending resistance, easily make surface of the work wear and tear, affect the serviceability of workpiece.
Summary of the invention
The object of this invention is to provide a kind of structure simple, the bend punching die that bending is reliable and stable.
The present invention is achieved through the following technical solutions:
A kind of bend punching die, comprise upper bolster, upper padding plate, train wheel bridge, cope match-plate pattern, lower bolster, lower bolster and die shoe, it is characterized in that: described upper bolster lower end is installed with bending punching, described bending punching matches through upper padding plate, train wheel bridge and cope match-plate pattern successively, side bending wall is rushed in described bending, described lower bolster is provided with into son, described enter sub-side be provided with into groove, described enter groove and bending wall align, described enter sub-bottom be provided with limited block, described limited block is screwed and is arranged on lower bolster.
Further, described upper bolster is provided with nitrogen spring, and described nitrogen spring rushes with bending and is connected.
Further, described cope match-plate pattern is provided with jigger pin.
Further, described lower bolster is provided with successively inner position punching and outside fix punching.
The invention has the beneficial effects as follows: this mould structure is reasonable, simple to operate, ensure that stability and the reliability of bending, and the special construction utilizing bending to rush, decrease the bending resistance in Forging Process, reduce the disqualification rate that workpiece produces because of the wearing and tearing in Forging Process.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bend punching die of the present invention;
Fig. 2 is the structural representation of bending punching;
Fig. 3 is the structural representation into son.
Wherein: 1, upper bolster, 2, upper padding plate, 3, train wheel bridge, 4, cope match-plate pattern, 5, die shoe, 6, lower bolster, 7, lower bolster, 8, bending punching, 9, bending wall, 10, enter son, 11, enter groove, 12, limited block, 13, nitrogen spring, 14, jigger pin, 15, inner position punching, 16, outside fix punching.
Detailed description of the invention
A kind of bend punching die as shown in Figure 1, comprise upper bolster 1, upper padding plate 2, train wheel bridge 3, cope match-plate pattern 4, lower bolster 7, lower bolster 6 and die shoe 5, upper bolster 1 lower end is installed with bending punching 8, bending punching 8 matches through upper padding plate 2, train wheel bridge 3 and cope match-plate pattern 4 successively, 8 side bending walls 9 are rushed in bending, lower bolster 7 is provided with into son 10, entering sub 10 sides is provided with into groove 11, enter groove 11 to align with bending wall 9, enter sub 10 bottoms and be provided with limited block 12, limited block 12 is screwed and is arranged on lower bolster 7.Upper bolster 1 is provided with nitrogen spring 13, and nitrogen spring 13 and bending are rushed 8 and be connected, and cope match-plate pattern 4 is provided with jigger pin 14, lower bolster 7 is provided with successively inner position punching 15 and outside fix punching 16.
The bending process that cooperatively interacted that the present invention is rushed 8 by bending and entered between son 10, this mould structure is reasonable, simple to operate, ensure that stability and the reliability of bending, and the special construction utilizing bending to rush, decrease the bending resistance in Forging Process, reduce the disqualification rate that workpiece produces because of the wearing and tearing in Forging Process.
