Description
Technical field
The utility model belongs to technical field of mold, relates to a kind of Trimming Die, the waste material shear constitution on particularly a kind of Trimming Die.
Background technology
Longer at stamping material, stamped workpieces more for a long time, feeding for convenience, design is installed the waste material cutter additional at the material tail usually, the patrix cutting edge of the edge iron of mould and the counterdie cutting edge of edge iron carry out work, the border of product is cut away, along with mould continues to move downward, cut deburring waste material is along with continuing to move to waste material cutter place, patrix moves downward, and the cutting edge that the waste material cutter is corresponding therewith cuts off waste material, and waste material slides on the press table top, then waste material centralized collection to ash can is got final product, be convenient to the collection of waste material.
At present, die design stage in the early stage of the project, mould design producer is often when plan boundary is the deburring class mould of product of circular arc line, adopt the waste material cutter of ordinary construction, common waste material knife structure is square structure, and contacting the border that mostly is product with the border of product is smooth and state straight line, this structure mainly consists of the following components: 1. scrap cutter cutting edge 2. waste material cutter bases 3. set bolts, by being bolted on the die ontology, the structure of this kind waste material cutter is for box part, and when the trimming line of product is the product deburring of circular arc line, it is bad that waste material cutter and the deburring section of product contact effect, may cause waste material not cut off smoothly, influence the production efficiency and the quality of production.
Trimming line is meant product boundary line between deburring finished product and the deburring waste material when deburring in this article, trimming line is the main foundation that is used for determining shear knife and waste material cutter position, the deburring section is that waste part is sheared the new boundary face that the back produces on finished product, the smooth degree of this deburring section depends on the performance of shear knife and the performance of processing mold, the waste material cutter of above mentioning contact with the deburring section of product effect bad be because the thickness of product greater than the height of waste material cutter blade, like this, the shank portion of waste material cutter will inevitably contact with the deburring section of product, if the shank portion of edge iron can not well cooperate with the deburring section of product, make the handle of a knife of edge iron scratch the deburring section of product, be considered as the failure of the bad or trim process of deburring effect, the utility model is exactly contingent the problems referred to above when solving the trim process of this product.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, waste material shear constitution on a kind of Trimming Die has been proposed, the technical problem that the utility model solves is to make the waste material cutter can be better and the product EDGE CONTACT, cuts off waste material smoothly, and can not scratch product.
The purpose of this utility model can realize by following technical proposal:
Waste material shear constitution on a kind of Trimming Die, Trimming Die comprises cope match-plate pattern, lower bolster, and be fixed on drift on the cope match-plate pattern, it is characterized in that, the side of described drift has cambered surface one, and this waste material shear constitution comprises that some handles are fixed on the lower bolster and blade waste material cutter up, and described waste material cutter is distributed in the side-lower of drift, the handle of a knife of described waste material cutter has cambered surface two towards a side of drift, can make described cambered surface one tangent with cambered surface two when moving down drift.
Operation principle of the present utility model is: when this Trimming Die is curve at the workpiece trimming line, when the edge line that is to say drift is curve, during operation, the workpiece outer rim forms the waste material of an annular, the waste material cutter cuts into plurality of sections with waste material, waste material is taken out easily or drop, for preventing that workpiece from contacting with the waste material cutter is the damage of waste material cutter to workpiece, curved surface is made at the position that the shank of waste material cutter need be contacted with workpiece, the shape of workpiece derives from drift, so, when the shank of waste material cutter is can be with the side end face of drift tangent, can guarantee that waste material is cut off fully by the waste material cutter, and the shank of waste material cutter can not scratch workpiece.
In the waste material shear constitution on above-mentioned a kind of Trimming Die, the blade of described waste material cutter is linearly to be arranged on the upper surface of handle of a knife, and blade is perpendicular to the common tangent of cambered surface one and cambered surface two.Can guarantee like this can cut off smoothly when waste material is cut, waste material can be fallen into reject chute smoothly.
In the waste material shear constitution on above-mentioned a kind of Trimming Die, the handle of a knife of described waste material cutter is cylindrical shape or oval column or semi-cylindrical.Having avoided traditional flat column waste material cutter is curved surface and waste material cutter when being in workpiece indent position at workpiece, and the handle of a knife of waste material cutter scratches workpiece, influence the precision that workpiece is processed.
In the waste material shear constitution on above-mentioned a kind of Trimming Die, the handle of a knife of described waste material cutter is plugged on the lower bolster.
In the waste material shear constitution on above-mentioned a kind of Trimming Die, described waste material cutter has three at least, and is evenly distributed on the side-lower of described drift.As much as possible waste material is cut into a plurality of segments, so that waste material is fallen in the reject chute smoothly.
Compared with prior art, the utility model improves traditional flat column waste material cutter, change the waste material cutter into cylindrical shape or oval column or semi-cylindrical, it is damage to workpiece that the shank that has prevented the waste material cutter contacts with workpiece, the machining accuracy when having guaranteed the deburring operation.
