Description
Technical field
This utility model belongs to metal plastic deformation processing technique field, relates in particular to the high shearing resistance with interchangeable function and combines former.
Background technology
Currently used high shearing resistance rivet is generally molectron, is made up of core bar and the shaft of rivet, six square toes rivet nut structure chart such as Fig. 2. For the rivet nut of Fig. 2 structure, common processing method has two kinds.
The first processing method is the blank that first upsetting goes out round end, assists to cut out six square toes portions with a trimming equipment, and the shortcoming of this method is waste material, and part head is yielding, and part shape size is not easy to ensure. Metal streamline is cut off, and properties of product are poor. After trimming, shape surface roughness is poor, and processing effect is low.
The second processing method is that direct upsetting goes out nose shape. Due to the design defect of mould itself, mould is unitary mould. Six square toes portions and bar portion are same core rods, and mould is also difficult to, and size is difficult to ensure that, can not be completely secured after processing on product requirement, then is undertaken adding work by the method for turning. Production cost is high, and Product processing can not disposable machine, and working (machining) efficiency is low, owing to this mould is unitary mould, slightly damages during upsetting, and mould is just scrapped, and processing cost improves.
Summary of the invention
Former is combined in a kind of simple in construction that the purpose of this utility model is in that to overcome disadvantages mentioned above and provides, highly effective, the high shearing resistance with interchangeable function easy to operate, economically viable.
This utility model purpose and solve its technical problem underlying and realize by the following technical solutions:
Former is combined in high shearing resistance with interchangeable function of the present utility model, including front core rod, rear core rod, overcoat, wherein: front core rod and rear core rod are contained in jacket internal, the sliding conjunction of front core rod is arranged on overcoat front portion, the sliding conjunction of rear core rod is arranged on overcoat rear portion, front core rod and rear core rod are positioned by end contact, and rear core rod is by rear core rod gland pressing on the coat.
Former is combined in the above-mentioned high shearing resistance with interchangeable function, wherein: front mould core inner is provided with die cavity holes B, and rear mold core inner is provided with die cavity holes A.
Former is combined in the above-mentioned high shearing resistance with interchangeable function, wherein: die cavity holes B diameter is more than die cavity holes A, and die cavity holes A and die cavity holes B is coaxially distributed.
Former is combined in the above-mentioned high shearing resistance with interchangeable function, and wherein: rear core rod gland is through hole external thread structure, rear core rod gland is connected by screw thread with overcoat.
This utility model compared with the existing technology has clear advantage and beneficial effect. From above technical scheme, high shearing resistance with interchangeable function of the present utility model is combined in former, front mould core inner is provided with die cavity holes B, rear mold core inner is provided with die cavity holes A, and die cavity holes B diameter is more than die cavity holes A, and die cavity holes A and die cavity holes B is coaxially distributed, realize the placement to upsetting part head of the die cavity holes Type B, the lumen pore A placement to upsetting part bar portion, upsetting part head and bar portion complete in same assembling die, interchangeable function processing plurality of specifications part in a mould; Front core rod and rear core rod are contained in jacket internal, and the sliding conjunction of front core rod is arranged on overcoat front portion, and the sliding conjunction of rear core rod is arranged on overcoat rear portion, during part upsetting, the front core rod of mould and rear core rod interchangeability are fine, can change at any time, simultaneously, after adopting two core rods, the geomery tolerance of part is easily guaranteed that, and surface roughness is low, when using upsetting extrusion, metal streamline is not switched off, part strength is good, and product quality can be sufficiently ensured; Stock utilization high (substantially the utilization rate of 100%), die life is longer, and production efficiency is higher, uses equipment few, and part manufacturing cost reduces. In a word, this utility model simple in construction, highly effective, easy to operate, economically feasible, it is suitable for promoting the use of of high shearing resistance six square toes rivet nut processing.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, combine former detailed description of the invention, structure, feature and effect thereof to according to the high shearing resistance with interchangeable function that the utility model proposes, describe in detail as after.
Referring to Fig. 1 to Fig. 2, former is combined in high shearing resistance with interchangeable function of the present utility model, including front core rod 1, rear core rod 2, overcoat 4, wherein: it is internal that front core rod 1 and rear core rod 2 are contained in overcoat 4, it is anterior that the sliding conjunction of front core rod 1 is arranged on overcoat 4, the sliding conjunction of rear core rod 2 is arranged on overcoat 4 rear portion, and front core rod 1 and rear core rod 2 are positioned by end contact, and rear core rod 2 is pressed together on overcoat 4 by rear core rod gland 3. Front core rod 1 is internally provided with die cavity holes B6, and rear core rod 2 is internally provided with die cavity holes A5.
Die cavity holes B6 diameter is more than die cavity holes A5, and die cavity holes A5 and die cavity holes B6 is coaxially distributed. Rear core rod gland 3 is through hole external thread structure, and rear core rod gland 3 is connected by screw thread with overcoat 4.
During use, raw material is put in the die cavity of die cavity holes A5, and under punch die effect, material is sent to predetermined location. Push rod in die cavity holes B6 prevents material to move to former direction, and the material outside die cavity holes A5 is gradually filled with the die cavity of die cavity holes B6. After die cavity is full of, punch die stops travelling forward, and returns after somewhat stopping. In former, push rod is under the effect of knock-out mechanism, releases part, completes raw-material necking down and shape is made in head upsetting, and part upsetting system machines. This utility model simple in construction, highly effective, easy to operate, economically feasible, be suitable for promoting the use of of high shearing resistance six square toes rivet nut processing.
The above, it it is only preferred embodiment of the present utility model, not this utility model is done any pro forma restriction, any without departing from technical solutions of the utility model content, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still falls within the scope of technical solutions of the utility model.
