Detailed description of the invention

In order to be more clearly understood from the technical characteristic of utility model, purpose and effect, now comparison accompanying drawing illustrates detailed description of the invention of the present utility model, and the most identical label represents identical parts.For making simplified form, only schematically show the part relevant to the utility model in each figure, they do not represent its practical structures as product.

Such as Fig. 1, shown in 2, the utility model includes hard alloy top hammer 1 to be processed, the top of hard alloy top hammer 1 to be processed is provided with upper punch 2, the lower central position side of the being provided with cushion block 3 of hard alloy top hammer 1 to be processed, the surrounding of side's cushion block 3 is movably installed with a point lobe heelpiece 4 respectively, the outer cover of described point of lobe heelpiece 4 is equipped with the die sleeve 5 suitable with hard alloy top hammer 1 outer surface to be processed and upper punch 2 middle and lower part, angle between inner surface and the vertical line of described die sleeve 5 and hard alloy top hammer to be processed 1 outer surface junction is the first angle, angle between inner surface and the vertical line of described die sleeve 5 and point lobe heelpiece 4 outer surface junction is the second angle, the angle of described second angle is more than the angle of the first angle；Outside described hard alloy top hammer to be processed 1, skewed surface is divided into lower outside skewed surface 6 and upper outside skewed surface 7, described lower outside skewed surface 6 is skewed surface 14mm to 16mm place outside the bottom extremely hard alloy top hammer 1 to be processed of hard alloy top hammer 1 to be processed, described upper outside skewed surface 7 is on the top of lower outside skewed surface 6, angle between inner surface and the horizontal line of described point of lobe heelpiece 4 and skewed surface 6 junction, lower outside is the 3rd angle, angle between inner surface and the horizontal line of described point of lobe heelpiece 4 and skewed surface 7 junction, upper outside is the 4th angle, the angle of described 3rd angle is less than the angle of the 4th angle.Outside the extremely hard alloy top hammer 1 to be processed of the described bottom that lower outside skewed surface 6 is hard alloy top hammer 1 to be processed at skewed surface 15mm.The angle of the first described angle is 2 °, and the angle of the second angle is 3 °～4 °, and the angle of the 3rd angle is 40 °～41 °, and the angle of the 4th angle is 46 °.The angle of the second described angle is 3 °, and the angle of the 3rd angle is 41 °.

Being placed by side's cushion block 3 during use the utility model and go up in place, then the surrounding at side's cushion block 3 places four points of lobe heelpieces 4 respectively, by the top of hard alloy top hammer 1 side of being placed on to be processed cushion block 3, is set with Upper Die-sleeve 5, finally places upper punch 2 and can process；Hard alloy top hammer mould die sleeve 5 described in the utility model and a point lobe heelpiece 4 all use double angle design, die sleeve 5 bottom knockout angle 3 ° also matches with angle with point lobe heelpiece 4 outer round surface, the angle of die sleeve the first angle is 2 °, the angle dividing the 4th angle in lobe heelpiece 4 is 46 °, the angle of the 3rd angle is 41 °, and the top hammer blank that can realize producing carries the little inclined-plane of L length.According in sintering process, the constriction coefficient at each position of top hammer is inconsistent, is 3 ° the angle design of the second angle of die sleeve 5, can strengthen top hammer wedge angle size so that whole top hammer blank tapering is close to 1.5 °, and handling mould will not be damaged a point lobe heelpiece 4 simultaneously；The angle of the 3rd angle in described point of lobe heelpiece 4 is 41 °, can realize top hammer blank and carry the little inclined-plane of L length.Therefore it is little that the top hammer using the utility model to produce has surplus, saves material, and rate of processing loss is less than 2%, reduces production cost, the advantage improving working (machining) efficiency.
