Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of numerical control punch die drift.
Background technology
Mould is usually used in stamping-out, shaping and punching, die forging, cold-heading, extruding, metallic sintered products is suppressed, compression casting, and engineering plastics, rubber, pottery waits in the compression moulding of goods or the formed machining of injection moulding, mould has specific profile or cavity shape, the contour shape that application has cutting edge can make blank be separated by outline line shape, application cavity shape can make blank obtain corresponding three-dimensional shape, mould generally comprises dynamic model and cover half two parts, the two partable, load blank time separately or take out product, product is made to be separated with blank or to be shaped when closing up, mould is precision instrument, complex-shaped, bear the expansive force of blank, to structural strength, rigidity, case hardness, surface roughness and machining accuracy all have higher requirements, therefore the development level that mould is produced is one of important symbol of machine-building level.
Along with the high speed development of national economy, the demand of market to mould constantly increases, in recent years, mould industry is always fast-developing with the growth rate of about 15%, in mould industry, diel oneself occupy the sizable space of manufacturing industry, and the requirement of product to mould is also more and more tighter, there is very large development cost in mould development and manufacture, in the environment day by day competed, only have the manufacturing cost of reduction each side thus the one seat of ability occuping market.
Small size mold and punching head in existing numerical control press is mostly holistic drift, and after the cutting edge wearing and tearing of drift bottom, whole Zhi Chongtou scraps and can not use, and needs the drift more renewed.Because the material of drift is high-speed tool steel, manufacturing cost is high, thus causes very large waste, and minority uses knockdown drift, and because structure is more complicated, the accuracy of manufacture requires high, and cost increases a lot, is unfavorable for batch production.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of numerical control punch die drift.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of numerical control punch die drift, comprising: connecting rod, punch body and replacement head, and described connecting rod is connected with described punch body;
Described connecting rod is provided with external screw thread with described punch body opposite end;
Described punch body offers connecting hole with described connecting rod opposite end, and described punch body Side symmetrical offers two fixing holes, and described fixing hole runs through described connecting hole;
Described replacement head is connected with described punch body, described replacement head comprises joint pin, limiting stand and drift blade, described joint pin, described limiting stand are connected successively with described drift blade, described joint pin inserts in described connecting hole, described joint pin side opening is provided with a spacing hole, and described spacing hole runs through described joint pin.
In the utility model preferred embodiment, the mode by welding between described connecting rod with described punch body is fixed.
In the utility model preferred embodiment, described fixing hole matches with described spacing hole.
The beneficial effects of the utility model are: a kind of numerical control punch die drift of the utility model, and this mold and punching head is fabricated structure, and structure is simple, does not need to carry out integral replacing, can carry out local replacing, and it is convenient to change, and can effectively reduce the cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of numerical control punch die drift of the utility model.
Fig. 2 is the front view of a kind of numerical control punch die drift of the utility model replacement head.
In accompanying drawing, the mark of each parts is as follows: 1, connecting rod; 2, punch body; 3, replacement head; 4, connecting hole; 5, fixing hole; 6, joint pin; 7, limiting stand; 8, drift blade; 9, spacing hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises: a kind of numerical control punch die drift, comprise: connecting rod 1, punch body 2 and replacement head 3, described connecting rod 1 is connected with described punch body 2, and the mode by welding between described connecting rod 1 with described punch body 2 is fixed.
Described connecting rod 1 is provided with external screw thread with described punch body 2 opposite end, and this drift is connected with attacking head by external screw thread.
Described punch body 2 offers connecting hole 4 with described connecting rod 1 opposite end, described punch body 2 Side symmetrical offers two fixing holes 5, described fixing hole 5 runs through described connecting hole 4, and described connecting hole 4, for being connected with described replacement head 3, makes it change more quick and convenient.
Described replacement head 3 is connected with described punch body 2, described replacement head 3 comprises joint pin 6, limiting stand 7 and drift blade 8, described joint pin 6, described limiting stand 7 are connected successively with described drift blade 8, described joint pin 6 inserts in described connecting hole 4, make described replacement head 3 can carry out local replacing at any time, thus reduce the cost manufactured.
Described joint pin 6 side opening is provided with a spacing hole 9, described spacing hole 9 runs through described joint pin 6, described fixing hole 5 matches with described spacing hole 9, make described fixing hole 5 coaxial with described spacing hole 9 during installation, then be locked by threaded rod and locking nut, finally reached the object be fixedly connected with.
Compared with prior art, a kind of numerical control punch die drift of the utility model, this mold and punching head is fabricated structure, and structure is simple, does not need to carry out integral replacing, can carry out local replacing, and it is convenient to change, and can effectively reduce the cost of manufacture.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
