Abstract
The utility model discloses a combined male die of a punching die, and relates to a die component. The combined male die comprises a male die base, wherein the male die base is made of Q235 steel, the male die base is fixedly connected with the lower surface of an upper die base through a fixing plate, the lower end of the male die base is detachably connected with a male die insert made of hard alloy, the lower surface of the male die base is provided with a groove, and the upper surface of the male die insert is provided with a protrusion matched with the groove. The combined male die is high in hardness and strength, long in service life, convenient to machine, low in manufacturing and maintenance cost and very practical.
Description
Technical field
The utility model relates to a kind of mold component, relates in particular to a kind of stamping die combined heave die.
Background technology
Punch forming is at room temperature, utilizes the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Be used for forming mould and be called stamping die, perhaps cold-punching mould, stamping die 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 mould design and manufacturing.The height of mould design and manufacturing technology level is one of important symbol of weighing a national product manufacture level height, is determining the development ability of quality, benefit and the new product of product to a great extent.The moulding section of stamping die comprises punch and die, directly determine the service life of stamping die the service life of punch and die, existing punch generally adopts the general tool steel to make, its service life is short, if punch adopts hardness and the high carbide alloy of intensity to make, then its service life is than high tens of times of general tool steel, when the workpiece size that will process was big, corresponding punch size was also bigger, if adopt carbide alloy to make, then die cost is very high, be the several times of ordinary steel molding jig even tens of times, and mould is made difficulty, processing cost height, if and punch damages then whole punch will be changed, cause waste.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of stamping die combined heave die, hardness and intensity height, and long service life, and easy to process, manufacturing and maintenance cost are low, very practical.
The technical solution of the utility model is: a kind of stamping die combined heave die, comprise the punch base, described punch base adopts the Q235 steel to make, the punch base is fixedly connected on the upper bolster lower surface by fixed head, punch base lower end is removably connected with punch insert, described punch insert adopts carbide alloy to make, and the punch base lower surface has groove, and the punch insert upper surface is provided with the projection with the groove coupling.
As preferably, have through hole on the punch base, the lower end hole wall of through hole is provided with internal thread, has up-small and down-big ladder hole on the punch insert, and punch insert removably connects by screw and punch base.
As preferably, described fixed head adopts 45 steel to make.
The beneficial effects of the utility model are: punch of the present utility model adopts edge to piece together structure, the punch insert of moulding section adopts carbide alloy to make, hardness and intensity height, it is little that long service life, punch insert are compared the solid punch volume, easy to process, manufacturing cost reduces greatly, punch insert and punch base removably connect, and change and repair conveniently, and be very practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of stamping die combined heave die comprises punch base 3, and described punch base 3 adopts the Q235 steel to make good combination property, long service life.Punch base 3 is fixedly connected on the upper bolster lower surface by fixed head 2, and in the present embodiment, as preferably, described fixed head 2 adopts 45 steel to make.Punch base 3 lower ends are removably connected with punch insert 1, and described punch insert 1 adopts carbide alloy to make, and is preferably YG20.Punch base 3 lower surfaces have groove, and punch insert 1 upper surface is provided with the projection with the groove coupling.Punch base 3 and punch insert 1 relatively moved when groove and projection had been avoided stamping-out, had guaranteed punching precision.In the present embodiment, as preferably, have through hole 4 on the punch base 3, the lower end hole wall of through hole 4 is provided with internal thread, has up-small and down-big ladder hole on the punch insert 1, and punch insert 1 removably connects by screw 5 and punch base 3.Through hole 4 can reduce punch base 3 stress to be concentrated, and prolongs the service life of punch base 3.
More than a kind of stamping die combined heave die provided by the utility model has been carried out detailed introduction, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To change of the present utility model with to improve will be possible, and can not exceed design and the scope that accessory claim can be stipulated.
