The composite punching die body comprises a central hole punching convex die body, a rectangular hole punching convex die body and a punching concave die body, wherein the central hole punching convex die body and the rectangular hole punching convex die body are connected with the upper die base through a convex die fixing plate. The deep drawing forming blanking composite die body comprises a forming concave die body, a blanking concave die body and a deep drawing forming convex die body, wherein the blanking concave die body is directly fixed on the upper die base, a discharging rubber block and a limiting gasket are arranged between the forming concave die body and the upper die base in a padding mode, and the deep drawing forming convex die body and the punching concave die body are fixed on the lower die base. After stamping of a workpiece is carried out by the application of the horn basin stand stamping progressive die, the quality of the workpiece is ensured, and meanwhile the machining efficiency of the workpiece is further effectively improved.

Description

A kind of horn basin rack stamping progressive die

Technical field

The utility model relates to a kind of horn basin rack stamping progressive die, belongs to horn basin rack and manufactures field.

Background technology

In traditional horn basin rack Sheet Metal Forming Technology process, use blanking, drawing and forming mould, blanking die, rush the how secondary moulds such as mesopore, flanging composite die, and the cooperation between mould needs the workman with people's hand operated, and cost of labor is higher, and production efficiency is also very low.

The utility model content

The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of horn basin rack stamping progressive die is provided, and effectively raises the production efficiency of horn basin rack.

The technical solution of the utility model is: a kind of horn basin rack stamping progressive die, comprise upper bolster, die shoe, die shank, also comprise drawing and forming blanking compound die and composite punching mould, described composite punching mould comprises and rushes the centre bore punch, rush oblong aperture punch and punching concave die, describedly rush the centre bore punch and rush the oblong aperture punch and be connected with upper bolster by punch retainer, described drawing and forming blanking compound die comprises female die for forming, blanking die and drawing and forming punch, described blanking die is directly fixed on upper bolster, between described female die for forming and upper bolster, be lined with discharging block rubber and limiting gasket, described drawing and forming punch and punching concave die are fixed on die shoe.

The beneficial effects of the utility model are: the utility model is made in drawing and forming blanking composite die and compound punching mould on same secondary mould and forms progressive die, has effectively reduced cost of labor, and production efficiency improves greatly.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1. upper bolster, 2. die shoe, 3. die shank, 4. drawing and forming blanking compound die, 41. female die for formings, 42. blanking dies, 43. drawing and forming punch, 5. composite punching mould, 51. rushes centre bore punch, 52. and rushes oblong aperture punch, 53. punching concave die, 6. punch retainer, 7. discharging block rubber, 8. limiting gasket.

The specific embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

As shown in Figure 1, a kind of horn basin rack stamping progressive die, comprise upper bolster 1, die shoe 2, die shank 3, also comprise drawing and forming blanking compound die 4 and composite punching mould 5, described composite punching mould 5 comprises and rushes centre bore punch 51, rush oblong aperture punch 52 and punching concave die 53, describedly rush centre bore punch 51 and rush oblong aperture punch 52 and be connected with upper bolster 1 by punch retainer 6, described drawing and forming blanking compound die 4 comprises female die for forming 41, blanking die 42 and drawing and forming punch 43, described blanking die 42 is directly fixed on upper bolster 1, between described female die for forming 41 and upper bolster 1, be lined with discharging block rubber 7 and limiting gasket 8, described drawing and forming punch 43 and punching concave die 53 are fixed on die shoe 2.The utility model accomplishes on same secondary mould to form the dark progressive die of a kind of first punching post-tensioning by drawing and forming blanking die 4 and composite punching mould 5, has improved greatly the ram efficiency of horn basin rack.Drawing coefficient large (material deformation is little) due to horn basin rack, horn basin rack is out of shape not too large in drawing process, can not have influence on intensity and the assembling process of basin frame, so use of this progressive die, when guaranteeing the horn basin rack quality, reduce cost of labor, and effectively raised the production efficiency of basin frame.
