Abstract

A punching die for metal water ripple products is composed of an upper die base, a blanking male die, a forming male die, an ejector plate, rubber, an ejector rod, a rubber supporting plate, a lower die plate, a blanking female die, a forming female die, a guide column, a guide sleeve, a base plate and a die handle. The punching die is characterized in that the whole appearance of the products can be punched on one die, and a second die is not needed to punch water ripple curved surfaces. The punching die is firm and reliable in movement, high in automation degree, suitable for punching products of different thicknesses, simple in structure, and convenient to install, debug and maintain.

Description

A kind of stamping die of metal water Corrugated product

Technical field

The present invention relates to metal forming and diel, is a kind of stamping die of metal water Corrugated product.

Background technology

At present, in the structure of diel, have compared with polymorphic type, by the character of operation, can be divided into: perforating die, knife edge die, notch die, parting die and edger.By the guidance mode of upper and lower mould, can be divided into: without open die and the guide plate die, guide post typo die, ball guide post typo die, the guide mould that have guiding of guiding.Method by goods feeding step pitch can be divided into: fixedly pin stop formula, movable pin stop formula, pin stop formula, pilot pin formula and side edge formula automatically.By the structure of emboss pit, can divide: whole mould and piece mould, can be divided into by the layout method of punch-die: formal dress mould and upside-down mounting mould.By discharge method, can divide: rigidity discharging mould and elasticity discharging mould.Above-mentioned various mold mechanism is because punch and coordinating all the time of guide plate do not depart from, so necessary good straight-through structure of adopting process performance of punch, on guide plate, must fill several gag lever posts, when its height is not worked by mould, control punch and enter groove, stop patrix to drop to bottom surface damage guiding accuracy.Guide-plate type blanking die on the other hand, the guiding of upper and lower mould is to rely on the matched in clearance of guide plate and punch to carry out, therefore, the fit clearance of guide plate and punch must be less than the gap of punch-die.For thin material, guide plate must be coupled to H6/h5 with coordinating of punch; And its cooperation is necessary for H8/h7 for thick material, guide plate must have enough thickness simultaneously, and punch is enclosed within all the time guide plate and slides up and down in hole, even if also do not depart from guide plate when punch rises to top dead centre.Therefore this mould is only suitable in the shorter forcing press of stroke, or the stroke eccentric press that can regulate.In sum, mould manufacture, debugging, installation, maintenance are extremely inconvenient, and die manufacturing cost is high, once a certain damage parts of mould just causes the corresponding damage of coordinate part part, while causing maintenance, will manufacture more substitute part.In order to overcome the deficiency of above-mentioned mold mechanism, I in conjunction with a line for many years manufacture and design experience, spy provides following a kind of mould to solve the deficiency of above-mentioned mould.

Summary of the invention

The present invention take a kind of stamping die of metal water Corrugated product to solve the deficiency of above-mentioned mold mechanism as example.Its operating principle is: when patrix is descending, by forming convax mould, coordinated the ripples shape flexure plane that stamps out workpiece with shaping groove, patrix continues descending, blanking punch, forming terrace die compressing top board and female die for forming move down, until blanking punch and blanking die stamp out the profile of workpiece, after workpiece is shaped completely, the bullet top power of the elastic force top board of molding concave die just ejects goods, blanking punching press water ripples of workpiece can be shaped like this, must second operation work punching press water ripples flexure plane, reached like this object by the whole goods of a secondary mould molding.A kind of stamping die of metal water Corrugated product, it is characterized in that: upper bolster (1) is fastenedly connected and is integrated with die shank (14), forming terrace die (3) is arranged in the stepped hole of blanking punch (2), backing plate (13), blanking punch (2) is fastened on upper bolster (1) with screw and pin, the guide pin bushing (12) being arranged on upper bolster (1) coordinates with guide pillar (11) glade plane space being arranged on die shoe (8), top board (4), shaping groove (10) is slidably mounted in blanking die (9), push rod (6) becomes matched in clearance with the hole on lower bolster (8), blanking die (9) is treated top board (4), molding concave die (10) uses screw fastening on lower bolster (8) after installing and regulating again.A kind of stamping die of metal water Corrugated product, solved the necessary good straight-through structure of adopting process performance of punch, on guide plate, must fill several gag lever posts, when its height is not worked by mould, control punch and enter groove, stop patrix to drop to the problem of bottom surface damage guiding accuracy.Solved mould manufacture, debugging, installation, maintenance extremely inconvenient, die manufacturing cost is high, once a certain damage parts of mould just causes coordinate part damage parts, causes the problem of maintenance difficult.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further described

Shown in figure:

Sectional side elevation when Fig. 1 is mould punching moulding

Fig. 2 is the top view of mould

In figure, numeral number represents respectively:

1---upper bolster 2---blanking punch 3---forming convax mould

4---top board 5---rubber 6---push rods

7---rubber supporting plate 8---lower bolster 9---blanking dies

10---molding concave die 11---guide pillar 12---guide pin bushings

13---backing plate 14---die shank

The specific embodiment:

Shown in figure, this mould can and stamp out ripples flexure plane by blanking of goods and be shaped.Its specific embodiment is: when mould is on forcing press, after installation and debugging, during punching press, upper mould is driven when descending by forcing press, and at this moment, forming convax mould (3) coordinates with molding concave die (10), stamps out the ripples flexure plane of goods.And at this moment patrix continues descending under the transmission of pressure mechanism pressure, blanking punch (2), forming convax mould (3) compressing top board (4) and molding concave die (10) move down, until blanking punch (2) and blanking die (9) stamp out the profile of goods, after workpiece is shaped completely, at this moment the bullet top power of molding concave die (10) just promotes top board (4) bullet and ejects goods.While driving part of the upper die to do punching press by forcing press when mould resets, contrary action reaches reset object.

Claims (1)

1. the stamping die of a metal water Corrugated product, it is characterized in that: upper bolster (1) is fastenedly connected and is integrated with die shank (14), forming convax mould (3) is arranged in the stepped hole of blanking punch (2), backing plate (13), blanking punch (2) is fastened on upper bolster (1) with screw and pin, the guide pin bushing (12) being arranged on upper bolster (1) coordinates with guide pillar (11) glade plane space being arranged on die shoe (8), top board (4), shaping groove (10) is slidably mounted in blanking die (9), push rod (6) becomes matched in clearance with the hole on lower bolster (8), blanking die (9) is treated top board (4), molding concave die (10) uses screw fastening on lower bolster (8) after installing and regulating again.
