The specific embodiment
Below, in conjunction with the accompanying drawings, describe the specific embodiment of the present utility model in detail.
The blanking die that the utility model provides comprise upper bolster, die shoe, be installed in the punch insert on upper bolster or the die shoe and be installed in die shoe or upper bolster on die plate insert.Wherein, described installation can realize by mode well known in the art, connects, welds, rivets or the like as bolt.And it still is on the die shoe, can decide according to arts demand that punch insert or die plate insert specifically are installed on the upper bolster.Common way is to be installed on the upper bolster with contacted the inserting of the waste part that will cut.That is to say that for example, the punch insert that is used for punching is installed in upper bolster, the die plate insert that is used for punching is installed in die shoe; The punch insert that is used for deburring is installed in die shoe, and the die plate insert that is used for deburring is installed in upper bolster.Certainly; situation as described herein mainly is at the mould of the heavy parts of stamping-out as vehicle exterior panel; for the stamping-out finding and only carry out single action; as only carrying out punching or only carrying out the mould of deburring, punch insert or die plate insert also can be integrally formed as whole patrix or counterdie with upper bolster or die shoe.
The cutting edge profile 1 that is used for the punch insert of punching and/or is used for the die plate insert of deburring is non-horizontal surface.
Wherein, why adopt " and/or " such wording, be for comprising multiple different situation.For example, only be used to carry out punching at blanking die, thereby include only under the situation of one or more groups punch insert that is used for punching and die plate insert, the cutting edge profile that then only will be used for the punch insert of punching is made non-horizontal surface.Only be used to carry out deburring at blanking die, thereby include only under the situation of one or more groups punch insert that is used for deburring and die plate insert, the cutting edge profile that then only will be used for the die plate insert of deburring is made non-horizontal surface.Be used for carrying out simultaneously punching and deburring at blanking die, thereby comprise that punch insert that one or more groups is used for punching and die plate insert and one or more groups are used under the situation of the punch insert of deburring and die plate insert, then will wherein be used for punching punch insert the cutting edge profile and be used for one of the cutting edge profile of die plate insert of deburring or both make non-horizontal surface simultaneously.
Why select punch insert that its cutting edge profile is made non-horizontal surface at one group of punch insert and die plate insert that is used for punching, be because at one group of punch insert that is used for punching and die plate insert, punch insert is to insert with the waste part of the product that will cut is contacted, therefore, change its profile shape and any influence can not arranged the forming shape of product.In like manner, why select die plate insert that its cutting edge profile is made non-horizontal surface at one group of punch insert and die plate insert that is used for deburring, be because at one group of punch insert that is used for deburring and die plate insert, die plate insert is to insert with the waste part of the product that will cut is contacted, therefore, change its profile shape and any influence can not arranged the forming shape of product.The die plate insert that is used for punching then can design according to the specific requirement of product forming shape with the cutting edge profile that is used for the punch insert of deburring.
In addition, the notion of " the cutting edge profile " mentioned among the application is conventionally known to one of skill in the art, just is meant, the close blanking die cutting edge place of inserting is promptly apart from the contacted surface of the product with treating stamping-out at the about 20-30 millimeter of cutting edge place.In the application's accompanying drawing, indicate with figure notation 1.And, described " non-horizontal surface " in other words so long as not the surface of level can, for example, can comprise inclined plane, arcwall face, wavy surface or cascaded surface or the like.Perhaps so long as can not with the corresponding face of the surface configuration of product.Because as long as this cutting edge profile is not whole level, promptly be not whole perpendicular to the stamping-out direction, when stamping-out, each stamping-out part of product is not to finish the stamping-out process simultaneously just, but the stamping-out process of sequentially progressively finishing is successively arranged so.Therefore, stamping-out can significantly reduce the required blanking pressure of blanking die, and then reduce the noise and the vibration of production environment under the prerequisite that guarantees identical stamping-out effect so by easy stages, and prolonged the service life of mould and press.
Illustrate, under the situation of carrying out punching, the big situation of line length summation in particularly many and/or hole for the quantity in hole, the cutting edge profile 1 that is used for the punch insert of punching can be for being inclined relative to horizontal the inclined plane of certain angle, as shown in Figure 1.Described tilt angle theta is usually according to the thick difference of product material and difference.When the thick t of material of product was between the 0.7-3 millimeter, described tilt angle theta was the 1-8 degree, is preferably the 2-5 degree; When the thick t of material of product was between the 3-10 millimeter, described tilt angle theta was the 1-12 degree, is preferably the 4-8 degree.
Perhaps, as selection, the cutting edge profile 1 that is used for the die plate insert of deburring also can as shown in Figure 2, have height difference H between highest point A and the lowest part B for having the arcwall face of certain height difference between highest point and the lowest part.Described difference in height is usually according to the thick difference of product material and difference.When the thick t of material of product was between the 0.7-3 millimeter, described height difference H was 0.5t-5t, is preferably 1t-3t; When the thick t of material of product was between the 3-10 millimeter, described height difference H was 0.2t-3t, is preferably 0.5t-1t.
Simultaneously, described arcwall face can be the arc-shaped surface with certain curvature, perhaps also can be the arcwall face that is made of the sectional inclined plane that is inclined relative to horizontal.Under the preferable case, the processing of mould for convenience, and consider that the arcwall face that is made of opposed facing inclined-plane can offset the side force that produces in the stamping-out process, therefore described arcwall face is the arcwall face that is made of the sectional inclined plane that is inclined relative to horizontal, as shown in Figure 3, that is to say that whole inserting is combined into by a plurality of inserting for a short time.At this moment, the angle of inclination on described inclined plane is usually also according to the thick difference of product material and difference.When the thick t of material of product was between the 0.7-3 millimeter, described angle of inclination was the 1-8 degree, is preferably the 2-5 degree; When the thick t of material of product was between the 3-10 millimeter, described angle of inclination was the 1-12 degree, is preferably the 4-8 degree.
Perhaps, as selection, the cutting edge profile 1 that is used for the die plate insert of deburring also can be wavy surface, promptly comprises at least two described arcwall faces.
Perhaps, as selection, the cutting edge profile 1 that is used for the die plate insert of deburring also can be cascaded surface, comprises that promptly to have certain height between at least two ladders and adjacent two ladders poor.Described difference in height is usually according to the thick difference of product material and difference.When the thick t of material of product was between the 0.7-3 millimeter, described height difference H was 0.5t-5t, is preferably 1t-3t; When the thick t of material of product was between the 3-10 millimeter, described height difference H was 0.2t-3t, is preferably 0.5t-1t.
Perhaps, as selection, the cutting edge profile 1 that is used for the die plate insert of deburring can also be male and fomale(M﹠F) arbitrarily, as long as can guarantee not to be the surface of level.
Be to be understood that, the situation that is used for punching is similar each other with the situation that is used for deburring, that is to say that the cutting edge profile 1 of the die plate insert that is used for deburring and the cutting edge profile 1 that is used for the punch insert of punching can adopt any non-horizontal surfaces such as aforesaid inclined plane, arcwall face, wavy surface, cascaded surface or male and fomale(M﹠F).
