Description

Metal button member diel

Technical field

The present invention relates to a kind of diel, specifically a kind of diel of metal button member, belong to Stamping Die Technology field.

Background technology

Material (being generally metalwork) is processed into a kind of technological equipment of part during diel in Cold Press Working.Punching press at room temperature utilizes the mould be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtain a kind of pressure processing method of required part.Can only complete same blank operation and just be single die in press ram each run, this single die is divided into: blanking die, perforating die and edger.Wherein blanking die is widely used in every field.Traditional blanking die major part between upper and lower die holder is all adopt guide plate to be used as connecting media, guide plate due to shape and structure, the unusual inconvenience when assembling; And due to guide plate be planar structure, just do not have what space between upper and lower die holder, this allows punch and matrix indirectly not have enough gaps; During operation, each parts just create very large friction, and mould is very easy to wearing and tearing, service life is low, and guide plate cannot carry out effective fixed guide when operation to raw material, allow raw material be easy to be subject to externalities and the bad phenomenon such as skew occur, machining accuracy is very low.

Summary of the invention

The object of the invention is to overcome above-mentioned weak point, thus a kind of metal button member diel is provided, there is better machining accuracy, in punching course, be less likely to occur skew, improve stamping quality.

According to technical scheme provided by the invention, metal button member diel comprises upper male mould and lower cavity die, upper male mould and lower cavity die are up and down just to setting, it is characterized in that: upper male mould is slidably connected on multiple guide post, the affixed upper clamping plate in multiple guide post upper ends, the affixed upper bolster in upper clamping plate upper end, upper bolster upper end Bonding pressure machine slide block; The face down end face of die of described upper male mould is provided with the T-shaped blanking die of multiple protrusion, and the face down end face of die of upper male mould is provided with a material blocking block and multiple latch; Lower cavity die is fixed on die shoe, lower cavity die is provided with multiple charging conduit T-shaped one to one with blanking die towards the end face of upper male mould, and lower cavity die is provided with a material blocking block hole corresponding with material blocking block and multiple with latch lock pin aperture one to one towards the end face of upper male mould; Lower cavity die is provided with multiple pilot hole arranged with guide post one_to_one corresponding, and multiple guide post is slidably connected in multiple pilot hole respectively, realizes the guide effect of upper male mould and lower cavity die.

Further, blanking die is two, and charging conduit is two.

Further, latch is four, and lock pin aperture is four.

Further, guide post and pilot hole are four.

Compared with the prior art the present invention has the following advantages:

Structure of the present invention is simple, compact, reasonable, easy to use, and guiding accurately, has better machining accuracy, is less likely to occur skew, improves stamping quality in punching course.

Detailed description of the invention

Embodiment in is by reference to the accompanying drawings further described by the present invention below:

As shown in Fig. 1 ~ 3, the present invention mainly comprises upper male mould 4 and lower cavity die 6, and upper male mould 4 and lower cavity die about 6 are just to setting.Upper male mould 4 is slidably connected on multiple guide post 5, the affixed upper clamping plate 3 in multiple guide post 5 upper ends, the affixed upper bolster 2 in upper clamping plate 3 upper end, upper bolster 2 upper end Bonding pressure machine slide block 1.During punching press, upper bolster is driven to move up and down by forcing press.

As shown in Figure 2, the face down end face of die 6 of described upper male mould 4 is provided with the T-shaped blanking die 11 of multiple protrusion, and meanwhile, the face down end face of die 6 of upper male mould 4 is provided with a material blocking block 9 and multiple latch 10.In embodiment as shown in Figure 2, described blanking die 11 is two, and latch 10 is four.

Lower cavity die 6 is fixed on die shoe 7, as shown in Figure 3, lower cavity die 6 is provided with multiple charging conduit 12 T-shaped one to one with blanking die 11 towards the end face of upper male mould 4, meanwhile, lower cavity die 6 is provided with a material blocking block hole 14 corresponding with material blocking block 9 and multiple with latch 10 lock pin aperture 13 one to one towards the end face of upper male mould 4.In embodiment as shown in Figure 3, described charging conduit 12 is two, and lock pin aperture 13 is four.

Lower cavity die 6 is provided with multiple pilot hole 8 arranged with guide post 5 one_to_one corresponding, and multiple guide post 5 is slidably connected in multiple pilot hole 8 respectively, realizes the guide effect of upper male mould 4 and lower cavity die 6.In embodiment as shown in Fig. 2 ~ 3, described guide post 5 and pilot hole 8 are four.

Operation principle of the present invention is: when punching press, and guide post and pilot hole play guide effect to upper male mould and lower cavity die, prevents from offseting in punching course.Forcing press drive upper bolster press down, upper male mould at upper bolster pressure to the lower cavity die on die shoe.Blanking block on upper male mould and lower cavity die and charging conduit have coordinated blanking punched work, and the latch on upper male mould and material blocking block form stop location to the workpiece of punching press, be less likely to occur skew, improve stamping quality in punching course.
