Description
Technical field
The utility model relates to formed punches, and in particular to a kind of formed punch for being punched out to hard material.
Background technique
Currently, in stamping parts manufacturing process, it may appear that the processing of many device to hole, and to the precise requirements of position
Higher and higher, punching press is that a kind of very high processing method of efficiency is widely welcome especially in terms of sheet fabrication.Punching
When plate thickness be generally less than or equal to the diameter of punching, if thickness is more than aperture, due to being limited by formed punch intensity, rush
Head is easily damaged, and the service life is shorter.
Utility model content
In order to overcome drawbacks described above, the utility model provides a kind of hard material pierce punch, which is suitable for not
The hard materials such as rust steel are punched out, long service life and the efficiency for improving punching.
The utility model is to solve technical solution used by its technical problem：
A kind of hard material pierce punch carries out rushing circular hole processing, including formed punch ontology, the formed punch sheet for the material that liquidates
Body includes sequentially connected hanging platform, punch body, tapered portion and the edge of a knife from top to bottom, and the lower end of the hanging platform is inclined-plane, described
The small head end on inclined-plane is fixedly connected with the upper end of punch body, the tapered portion be inverted rotary table, the diameter on rotary table top with
The diameter of punch body is identical, and the diameter of bottom end and the diameter of the edge of a knife are identical, and the knife edge surfaces are equipped with one layer of wear-resistant coating.
Preferably, stating formed punch ontology is SKH-9 high-speed steel formed punch, and the hardness of the formed punch ontology is described greater than HRC62 °
Wear-resistant coating is ALTIN coating.
Preferably, the diameter of the punch body is greater than Circularhole diameter 2mm or so.
Preferably, the formed punch ontology is an integral structure, and the height of the hanging platform is 8mm or so.
Preferably, the height of the edge of a knife, which is greater than, rushes material thickness 3mm or so.
The utility model has the beneficial effects that：Formed punch ontology in the utility model reaches its hardness by subzero treatment
HRC62 °, and carry out the processing of ALTIN vacuum coating on the surface of the edge of a knife and prolong to greatly strengthen the hardness and strength of formed punch
The service life of formed punch is grown；Its hanging platform is connect by inclined-plane with punch body, that is, the structure that hanging platform has gradient excessive, and
Its height is set as 8mm, compared with the formed punch that tradition has that height is 5mm hanging platform, greatly improves formed punch intensity, so that punching
Head is not easy to be pulled off；And do the diameter of punch body greatly as much as possible, the general unilateral 1mm or so greater than Circularhole diameter, and
Knife edge length, which accomplishes just to stretch out, rushes material 3mm, further ensures the intensity of formed punch.
Detailed description of the invention
Membrane stage figure is closed when Fig. 1 is utility model works；
Membrane stage figure is opened when Fig. 2 is utility model works；
In figure：10- formed punch ontology, 11- hanging platform, 12- punch body, 13- tapered portion, the 14- edge of a knife, 20- upper clamp plate, 30-
Baffle plate, 40- stripper plate, 50- rush material.
Specific embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
Embodiment：As depicted in figs. 1 and 2, a kind of hard material pierce punch rush at circular hole for the material 50 that liquidates
Reason, including formed punch ontology 10, the formed punch ontology 10 include sequentially connected hanging platform 11, punch body 12, taper from top to bottom
Portion 13 and the edge of a knife 14, the lower end of the hanging platform 11 are inclined-plane, the fixed company of the small head end on the inclined-plane and the upper end of punch body 12
Connect, the tapered portion 13 be inverted rotary table, the diameter on rotary table top and the diameter of punch body are identical, the diameter of bottom end with
The diameter of the edge of a knife 14 is identical, and 14 surface of the edge of a knife is equipped with one layer of wear-resistant coating.The utility model be suitable for stainless steel etc. compared with
Hard material (be particularly suitable for thickness in 0.8mm or more and rush material) carries out rushing circular hole processing, and mould part component is from top to bottom
It is followed successively by upper clamp plate 20, baffle plate 30 and stripper plate 40, formed punch ontology 10 is fixed in upper clamp plate 20, rushes material 50 and stripper plate pressure
It closes, when punching, upper clamp plate 20 drives formed punch ontology 10 to move downward, and the edge of a knife 14 in formed punch ontology breaks through material to complete pair
The process for rushing material punching.Hanging platform 11 in the utility model is connect by inclined-plane with punch body 12, and the top of hanging platform 11 is divided into
Cylindrical body, lower part are divided into frustum cone structure, and cylindrical body is identical with the top diameter of frustum cone structure, the bottom of frustum cone structure and formed punch master
The diameter of body is identical, and the diameter of cylindrical portion is greater than the diameter of punch body in hanging platform, that is, hanging platform has gradient excessive
