Description
Technical field
The invention belongs to metal plastic deformation processing technique field, relate in particular to the high shearing resistance combination former with interchangeable function.
Background technology
The high shearing resistance rivet of current use is generally sub-assembly, is made up of core bar and the shaft of rivet, and six square toes rivet nut structure charts are 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 processing, and size is difficult to ensure, after processing, product requirement can not ensure completely, then be undertaken adding work by the method for turning.Production cost is high, and Product processing can not disposablely machine, and working (machining) efficiency is low, and because this mould is unitary mould, slightly damage during upsetting, mould is just scrapped, and processing cost improves.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and a kind of structure of providing is simple, highly effective, easy to operate, the economically viable high shearing resistance combination former with interchangeable function.
The object of the invention and solve its technical problem underlying and realize by the following technical solutions:
High shearing resistance combination former with interchangeable function of the present invention, comprise 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 located by end contact, and rear core rod by the pressing of rear core rod gland on the coat.
The above-mentioned high shearing resistance combination former with interchangeable function, wherein: front mould core inner is provided with die cavity holes A, rear mold core inner is provided with die cavity holes B.
The above-mentioned high shearing resistance combination former with interchangeable function, wherein: die cavity holes A diameter is greater than die cavity holes B, and die cavity holes A and die cavity holes B coaxially distributes.
The above-mentioned high shearing resistance combination former with interchangeable function, wherein: rear core rod gland is through hole external thread structure, rear core rod gland is connected by screw thread with overcoat.
The present invention compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, of the present invention with in the high shearing resistance combination former of interchangeable function, 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 greater than die cavity holes A, and die cavity holes A and die cavity holes B coaxially distributes, realize the placement of die cavity holes Type B to upsetting workpieces head, lumen pore A is to the placement in upsetting workpieces bar portion, and upsetting workpieces 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 very well, can be changed, simultaneously at any time, after adopting two core rods, the geomery tolerance of part easily ensures, surface roughness is low, when using upsetting extrusion, metal streamline is not cut-off, part strength is good, and product quality can be ensured fully; Stock utilization high (being essentially the utilization rate of 100%), die life is longer, and production efficiency is higher, and use equipment few, part manufacturing cost reduces.In a word, structure of the present invention is simple, highly effective, easy to operate, economically feasible, is applicable to promoting the use of of high shearing resistance six square toes rivet nut processing.

Fig. 2 is the structural representation of six square toes rivet nuts.
Identify in figure:
1, front core rod; 2, rear core rod; 3, rear core rod gland; 4, overcoat; 5, die cavity holes A; 6, die cavity holes B; 7, six square toes rivet nuts.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to the high shearing resistance combination former detailed description of the invention with interchangeable function proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
See Fig. 1 to Fig. 2, high shearing resistance combination former with interchangeable function of the present invention, comprise front core rod 1, rear core rod 2, overcoat 4, wherein: it is inner 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 located by end contact, and rear core rod 2 is pressed together on overcoat 4 by rear core rod gland 3.Front core rod 1 inside is provided with die cavity holes B6, and rear core rod 2 inside is provided with die cavity holes A5.
Die cavity holes B6 diameter is greater than die cavity holes A5, and die cavity holes A5 and die cavity holes B6 coaxially distributes.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, the die cavity of die cavity holes A5 put into by raw material, and under punch die effect, material is sent to predetermined location.Push rod in die cavity holes B6 prevents material to the motion of former direction, and the material outside die cavity holes A5 is full of the die cavity of die cavity holes B6 gradually.After die cavity is full of, punch die stops travelling forward, and returns after stopping a little.In former, push rod is under the effect of knock-out mechanism, and release part, completes raw-material necking down and shape is made in head upsetting, and part upsetting system machines.Structure of the present invention is simple, highly effective, easy to operate, economically feasible, is applicable to promoting the use of of high shearing resistance six square toes rivet nut processing.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
