Abstract
The utility model belongs to the technical field of diamond tool sintered product manufacturing, and particularly relates to a cold pressing steel mould of a special-shaped diamond tool. The cold pressing steel mould comprises a lower punch, a female mould and an upper punch. A combined gasket formed by two semi-annular gaskets is arranged between the lower punch and the female mould. A plurality of padding through holes are formed in an arraying mode along the axial direction in the female mould and penetrate through the upper end face and the lower end face of the female mould. An annular boss is arranged at the center position of the end face, matched with the upper punch, of the female mould. A plurality of cylindrical punches which correspond to and are matched with the padding through holes in the female mould are arranged on the lower punch toward the female mould. Each cylindrical punch is coaxially provided with an in-taking blind hole which is matched with a diamond tool grinding head handle. A central hole matched with the annular boss of the female mould is arranged at the center of the end face, matched with the female mould, of the upper punch. The height of the cylindrical punch is smaller than the sum of the thicknesses of the combined gasket and the female mould. The cold pressing steel mould is simple in structure and reasonable in design, labor cost is lowered, working time is saved, product production cost is saved, product coaxiality is high, production efficiency is high, and accordingly the cold pressing steel mould is very suitable for popularization and application.

For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of punching block mould of colding pressing of special-shaped diamond tool; comprise undershoot; former and upper punch; be provided with the bonded washer that two semi-circular packing rings consist of between undershoot and the former; described former runs through vertically the upper and lower end face annular array and is provided with a plurality of filler through holes; its with end face that upper punch cooperates on the center be provided with annular boss; undershoot is provided with a plurality of cylindric drift corresponding with filler through hole on the former and coupling towards the former direction; coaxial being provided with the diamond tool grinding-head handle is complementary taken in blind hole on each cylindric drift; the center is provided with the centre bore that is complementary with the former annular boss on upper punch and the end face that former cooperates, and the height of described cylindric drift is less than the thickness sum of bonded washer and former.
Also be provided with annular groove, the diameter of the slightly larger in diameter of annular groove annular boss on former on described upper punch and the end face that former cooperates.
Described centre bore is through hole or blind hole.
Operation principle of the present utility model is:
The utility model cold stamping die is designed to branched annular arrangement, and grinding-head handle is implanted punching block in advance with the punching block precision-fit, and the design of seaming chuck disjunctor guarantees steel mold pressing intensity, and bottom knockout is adopted in the demoulding, and the assurance bond strength is not damaged.
The utility model is the mode that adopts the sintering of colding pressing again at technological principle, drilling rod is put into punching block together throw in metal powder, then is pressed into regulation density at cold press, the then demoulding, and the beneficial effect of technical solutions of the utility model is:
1, structurally, the punching block mould of colding pressing of the utility model abnormity diamond tool comprises undershoot, former, upper punch and bonded washer, and simple in structure, wherein bonded washer is made of the two halves annular section, is convenient to remove; Reasonable in design, former boss and upper punch centre bore coupling are convenient to the location; The cylindric drift of undershoot and the filler through hole of former are complementary, and the coaxial grinding-head handle that is provided with of cylindric drift is taken in blind hole, guarantee the axiality of goods; The height of described cylindric drift guarantees that less than the thickness sum of bonded washer and former the rear cylindrical punch top of mould assembling is reserved with filling space.
2, in addition, compare with existing processing method, the goods after the utility model pre-compaction forming are put into separately the clock hood type furnace sintering, thereby reduction power consumption, save production cost, and goods are through the utility model once-forming, need not welding, technique is simple, needs man-hour shorter, has reduced labor cost, reduce simultaneously production cost, improved production efficiency.
3, structurally, also be provided with annular groove on upper punch described in the utility model and the end face that former cooperates, the diameter of the slightly larger in diameter of annular groove annular boss on former, guarantee to cooperate between upper punch and the former accurate, the press strengthi of raising punching block.
4, to sum up, the punching block mould structure of colding pressing of the utility model abnormity diamond tool is simple, reasonable in design, has reduced labor cost, saves man-hour, saves the production of articles cost, and the goods axiality is high, and production efficiency is high, therefore, is very suitable for promotion and implementation.
