Description

A kind of blanking die that can regulate blade clearance

Technical field

This is novel belongs to diel, is specifically related to a kind of blanking die that can regulate blade clearance.

Background technology

in automobile making, cold stamping sheet metal component is common member, and for different members, sheet thickness is often different, and corresponding blade clearance size is also just different, and thicker its blade clearance of plate is just larger.On the contrary, plate is thinner, and blade clearance is just less.If use same blade clearance, remove the large plate of stamping-out thickness drop, only can cause the generation of a large amount of burrs, even make upper and lower mould cutter piece damage.For the sheet metal component of different-thickness, mould factory tends to because panel thickness is inconsistent, the many covers of exploitation blanking die, and then increase cost.Therefore, need to carry out certain adjusting to the size of blanking die blade clearance, only in this way could effectively avoid the generation of above-mentioned defect.

Summary of the invention

The utility model object is to provide a kind of blanking die that can regulate blade clearance, and this mould can be realized the stamping and blanking of multiple different-thickness plate, avoids the generation of veining defect, improve versatility and the service life of mould, reduce production costs, and simple in structure, easy and simple to handle.

A kind of blanking die that can regulate blade clearance described in the utility model, is made up of the upper die component arranging in opposite directions and lower die component;

Eccentric swage that described upper die component comprises upper bolster, be connected with middle part below described upper bolster, be located by connecting on below described upper bolster and left side and described eccentric swage right side near patrix cutter piece;

Described lower die component comprises die shoe, is located at the lower die cutter piece holder in recess above described die shoe, is located by connecting on the lower die cutter piece above described lower die cutter piece holder, and the left side of described lower die cutter piece is corresponding with the right side of described patrix cutter piece;

It is characterized in that: be provided with between the left side wall of recess in the left side of described lower die cutter piece holder and above described die shoe two structures identical and near blade clearance adjust key, between the right side wall of the right side of described lower die cutter piece holder and recess above described die shoe, be provided with a wedge shape adjustment key.

Described lower die cutter piece holder and lower die cutter piece are adjusted key by blade clearance blade clearance are adjusted, and the key of wedge shape adjustment is simultaneously coordinating and using with blade clearance adjustment key, is used for adjusting blade clearance and fastening lower die cutter piece holder and lower die cutter piece; By adjusting the size of lower die cutter piece blade clearance, the utility model can be applied to the plate stamping and blanking of different-thickness.

Described a kind of blanking die that can regulate blade clearance, is characterized in that: described lower die component also comprises the roller type feeder, material-feeding bracket assembly and the roller type drawing mechanism that are located at successively from left to right above die shoe; The upper end of described material-feeding bracket assembly contacts with below plate material.

Further, the middle part of described eccentric swage is connected with below described upper bolster by caging bolt and caging bolt sleeve; Left part at described eccentric swage is provided with sleeve, coordinates a guide pin bushing in this sleeve, and this guide pin bushing coordinates with the guide pillar being located on described upper bolster.Upper bolster is connected with eccentric swage by caging bolt and caging bolt sleeve, eccentric swage is carried out spacing, and eccentric swage leads by guide pin bushing and guide pillar, to guarantee the guiding accuracy of eccentric swage in motion process.

Further, on the right part of described eccentric swage, be provided with Compress Spring, be provided with a spring pilot pin below the right part of described upper bolster, described Compress Spring is enclosed within the outside of this spring pilot pin.The effect of Compress Spring is that eccentric swage is exerted pressure, and pushes down plate material.And the effect of spring pilot pin is that Compress Spring is led, prevent that Compress Spring from occurring in the course of the work crooked.

The utility model adjusts key by blade clearance and wedge shape adjustment key is used in conjunction with, and carries out quickly and easily the adjustment of blade clearance, to adapt to the stamping and blanking of different plate discharge thickness, makes more rational blade clearance value of blade clearance convergence.Adjusting key by blade clearance and regulate blade clearance size, to meet the stamping and blanking of different material slab part materials, and then is mould factory, blanking factory, reduces widely mould development cost.

The specific embodiment

Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiment are for the present invention is described, and be not limited to limit the scope of the invention.The implementation condition adopting in embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.

A kind of blanking die that can regulate blade clearance shown in Figure 1, is made up of the upper die component arranging in opposite directions and lower die component;

Eccentric swage 2 that described upper die component comprises upper bolster 1, be connected with middle part below described upper bolster, be located by connecting on below described upper bolster and left side and described eccentric swage right side near patrix cutter piece 10;

Described lower die component comprises die shoe 11, is located at the lower die cutter piece holder 14 in recess above described die shoe, is located by connecting on the lower die cutter piece 15 above described lower die cutter piece holder, and the left side of described lower die cutter piece is corresponding with the right side of described patrix cutter piece;

Be provided with between the left side wall of recess in the left side of described lower die cutter piece holder 14 and above described die shoe two structures identical and near blade clearance adjust key 13, between the right side wall of the right side of described lower die cutter piece holder 14 and recess above described die shoe, be provided with a wedge shape adjustment key 16; Lower die cutter piece holder 14 adjusts key 13 by two blade clearances and a wedge shape adjustment key 16 is located by connecting with described die shoe.

Further, described lower die component also comprises the roller type feeder 12, material-feeding bracket assembly 17 and the roller type drawing mechanism 18 that are located at successively from left to right above die shoe 11; The upper end of described material-feeding bracket assembly 17 contacts with below plate material 19.

Further, the middle part of described eccentric swage 2 is connected with below described upper bolster 1 by caging bolt 6 and caging bolt sleeve 7; Be provided with sleeve 5 at the left part of described eccentric swage 2, coordinate a guide pin bushing 3 in this sleeve, this guide pin bushing coordinates with the guide pillar 4 being located on described upper bolster 1.
