Description
Technical field
The utility model relates to a kind of mould, particularly a kind of mould of press belt diclinic hole carbide alloy moulding pressed compact.
Background technology
The common production procedure of hart metal product is powder compaction, high temperature sintering, forms high rigidity, high-wearing feature, unmanageable alloy product.Because the limitation of powder compaction makes many special-shaped alloy products all can not pass through the mould straight forming, need after the pre-burning to be finish-machined to size again behind false add or the sintering.Because the high hard attribute of alloy needs modern advanced manufacturing process to realize, such as processing modes such as line cutting, electric sparks usually.These manufacturing process are very big to product cost influence: lathe cost height, processing charges are expensive, high to workman's specification requirement.So for special-shaped product, if can be by the innovation mould structure, directly compression moulding will reduce product cost greatly, shortens the production cycle, improves product competitiveness.
Abnormity alloy product profile is cylinder, and there are two inclined holes of symmetry inside, also has two deep grooves, and locking easily in knockout course is the difficult point that adopts the mould straight forming.This product existing processing technology path and consuming time as follows:
1. prefabricated blank is carried out the precision plane mill: 0.4 hour/part;
2. peripheral milling: 0.2 hour/part;
3. instrument grinds: 0.1 hour/part;
4. two inclined holes, 2.1 hours/part are processed in accurate fast wire;
5. check: 0.1 hour/part;
6. pack: 2 hours/200.
Analyzing above-mentioned processing technology can find, the time of two inclined holes of accurate fast wire processing is the longest, and its processing unit price is also the most expensive, and the production cost of consumption is maximum.In addition, work in-process is because the existence of angle also needs auxiliaries such as design processing auxiliary clamp.Under the situation of skilled processing, this production cost of products price reaches 133.4 yuan/part, and the price that arrives the client also will add profit, tax revenue etc.So the high price of alloy product has limited a large amount of employings of vast domestic consumer.
Summary of the invention
The technical problems to be solved in the utility model provides the mould of a kind of press belt diclinic hole carbide alloy moulding pressed compact.
For solving the problems of the technologies described above, the technical solution of the utility model is: the mould of a kind of press belt diclinic hole carbide alloy moulding pressed compact comprises base, former, core bar; Be placed in the following bottom that dashes of base, end face and the inner chamber taper fit of base, the inner wall sleeve of former bottom is contained in down the top that dashes, and the inwall of former bottom is sleeved on the top that the groove core that is positioned at base top surface is inserted simultaneously; Tiltedly core bar cooperates towards interior inclined hole with following, and the end of straight core bar and oblique core bar is by being threaded; The upper punch cover is inserted between former inwall and the straight core bar, and stop is placed in the end face of upper punch, and the gland cover is pressed in the end face of upper punch and stop.Described oblique core bar lower surface is positioned on the press bed, and the height of the face of rushing to summit under tiltedly core bar stretches out equals the thickness of moulding pressed compact, and diameter and the gradient towards inclined hole equals the desired diameter of moulding pressed compact inclined hole and gradient down.The diameter of described straight core bar equals the major axis of the horizontal ellipse section of oblique core bar.
The beneficial effects of the utility model are: adopt the present invention to substitute the technology of the accurate fast wire processing belt diclinic hole carbide alloy moulding pressed compact of traditional employing, do not acquire accurate fast wire machining tool, can improve work efficiency, reduce the production cost more than 50%.
