The utility model discloses can make the work piece just progressively to forge sharp shaping on a pair mould, reduce workman's intensity of labour, improve product quality, reduce the energy resource consumption, practice thrift manufacturing cost, popularize and apply and have good economy and social.
Description
Technical field
The utility model belongs to chain peculiar to vessel and mooring cable annex manufacture field, and particularly the mould structure of the especially big set square of a kind of mooring cable, is specially adapted to the connection of mooring cable.
Background technology
The especially big set square of mooring cable is mainly mooring cable provides a main chain work of simultaneously supporting two attached chains to connect, 120R4 super large standard mooring cable set square, shape is equilateral triangle, and the length of side is 1100mm, and thickness is 170mm, three holes are had in set square, diameter is 180mm, and pitch of holes is 430mm, and product material is 22MnCrNiMo, product design is also more special, and single products weight reaches about 1200 kilograms; Client requires quite high to Product Precision, and between pitch-row, tolerance only has 0.3mm, and surface can not defectiveness, finally also needs to carry out secondary flaw detection and hardness test.
, there is product yield low in the belt drop hammer forging that prior art uses, of poor quality, and need to use how secondary mould, energy resource consumption is large, and labour intensity is large, the problem of production technology poor stability.
Summary of the invention
The purpose of this utility model will solve the problems of the technologies described above.
The purpose of this utility model is achieved in that the mould structure of the especially big set square of a kind of mooring cable, comprise workpiece, counterdie, die hammer, it is characterized in that: described counterdie center of top is provided with V-shaped groove, two V-arrangement faces of V-shaped groove are arranged symmetrically with, angle between two V-arrangement faces is 60 °, V-arrangement face is provided with the circular arc chamfering of arc size Ra at V-shaped groove bottom land, is provided with the transition arc of arc size Rb between V-arrangement face and counterdie end face.
When circular arc chamfering, transition arc are not established in described V-arrangement face, top, V-arrangement face and V-arrangement face form equilateral triangle.
Described arc size Ra is greater than arc size Rb.
The center line of described die hammer and the centerline collineation in V-arrangement face, the bottom area of die hammer is greater than the topside area in V-arrangement face.
The utility model can make workpiece can progressively tagging is shaping on secondary mould, reduces the labour intensity of workman, improves product quality, reduce energy resource consumption, saved production cost, apply and have good economic and social benefit.

In figure: 1, workpiece; 2. counterdie; 3. die hammer; 201. arc size Ra; 202.V shape face; 203. arc size Rb.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
The mould structure of the especially big set square of a kind of mooring cable, comprise workpiece 1, counterdie 2, die hammer 3, described counterdie 2 center of top is provided with V-shaped groove, two V-arrangement faces 202 of V-shaped groove are arranged symmetrically with, angle between two V-arrangement faces 202 is 60 °, V-arrangement face 202 is provided with the circular arc chamfering of arc size Ra201 at V-shaped groove bottom land, is provided with the transition arc of arc size Rb203 between V-arrangement face 202 and counterdie 2 end face; When circular arc chamfering, transition arc are not established in described V-arrangement face 202, top, V-arrangement face 202 and V-arrangement face 202 form equilateral triangle; Described arc size Ra201 is greater than arc size Rb203; The center line of described die hammer 3 and the centerline collineation in V-arrangement face 202, the bottom area of die hammer 3 is greater than the topside area in V-arrangement face 202.
During concrete enforcement, 1), workpiece 1 material adopts material to be 22MnCrNiMo, and specification is that the round steel of ф 500 is as blank, piece weight blanking 1250 kilograms, uses gas furnace heating, 5 tons of die hammers forges, initial forging temperature is at 1200 DEG C, and final forging temperature is more than 850 DEG C; 2), first by blank upsetting on counterdie 2, to be then used on counterdie 2 progressively tagging, then fulling is to technical requirement, disposablely completes whole forging process, the forging quality of product also all meets technical requirement; 3), machined adopts numerical control gantry mill to process, two plane machinings program at Digit Control Machine Tool and process, processing is completed to the circular arc of three sides of product, triangle, three holes and chamfering etc. are disposable by numerical control gantry mill, and then another plane of processing that uses the same method; 4), the technical requirement of product and precision all meet drawing requirement, obtains the consistent accreditation of client.
The utility model mainly forges the shape that requires blank and size must close to the shape of product and size, thus can ensure that the interior tissue of product obtains higher guarantee, raw material are saved, 200% is risen than the class's of forging output on traditional belt drop hammer, improve product quality, energy resource consumption has saved more than 30% than producing on belt drop hammer, and alleviate labour intensity, this production technology have also been obtained guarantee safely.After this production successfully puts goods on the market, client speaks highly of this product design and serviceability, and customer demand is continuous successively.
Above-described embodiment of the present utility model; it is only the citing clearly illustrating that the utility model does; but be not used for limiting protection domain of the present utility model; all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by every claim.
