Abstract
The utility model belongs to the technical field of sheet metal stamping and manufacturing, and particularly relates to a sheet metal positioning pin which comprises a positioning pin body and a threaded rod. The positioning pin body and the threaded rod are connected in a threaded mode. The top of the positioning pin body is conical. The bottom of the positioning pin body is fixedly connected with a positioning base. Transition is achieved at the joint of the positioning base and the positioning pin body through a chamfer. The utility model relates to the technical field of sheet metal stamping and manufacturing, in particular to accurate positioning of a hot-pressing die blank. The sheet metal positioning pin is used for replacing a traditional sheet metal positioning pin, and solves the problems that an outdated positioning pin is prone to fracture, material coating and material blocking, and is short in service life. The sheet metal positioning pin is simple in structure, convenient to install, low in cost and high in reliability; blank positioning accuracy and stability of product side boundary are effectively improved, die debugging efficiency is improved, die production cycle and quality are ensured, and manufacturing cost is reduced.
Description
Technical field
The utility model belongs to metal sheet stamping manufacturing technology field, relates in particular to a kind of metal blank locating stud.
Background technique
When heat stamping and shaping, need to accurately locate blank, obtain stable product sideline, and then meet the tolerance of client to product, and dispense the loaded down with trivial details step of laser beam cutting.In blank drawing and moulding process, need blank the accurate location of row, and traditional straight rod type locating stud, can not meet the positioning requirements of large radian product, tend to make locating stud distortion or break.After blank moulding, product can be wrapped on locating stud, is difficult to take off, and can not capture for mechanism hand, and automation application is poor.
Model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of metal blank locating stud is provided, and extension plate material locating stud working life, solves its construction materials contract, and problem gets stuck.
The utility model for achieving the above object, by the following technical solutions: a kind of metal blank locating stud, it is characterized in that: comprise location shank and threaded stem, described threaded stem is threaded with described location shank, shank top, described location is coniform, shank bottom, described location is connected with positioning pedestal, excessive by chamfering with shank joint, described location on described positioning pedestal.
Preferably, described positioning pedestal is fixed on during work inserts.
Preferably, described chamfer angle is 30 °-45 °.
Preferably, shank top, described location is arranged with two right angle draw-in grooves.While being connected with threaded stem while installing for locating stud, spanner can be stuck on this groove, carry out fastening.
The beneficial effects of the utility model are: the utility model relates to metal sheet stamping manufacturing technology field, relate in particular to the accurate location of hot pressing die blank.The utility model is used for replacing traditional plate locating stud, has solved old-fashioned locating stud and has easily fractureed, and construction materials contract, gets stuck, the problem that the life-span is short.This simple in structure, easy for installation, with low cost, reliability is high, effectively improves the stability in blank positioning precision and product sideline, and then improves the efficiency of die debugging, guarantees mould manufacture cycle and quality, reduces manufacture cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model;
Fig. 3 is sectional view of the present utility model;
Fig. 4 is application schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, describe embodiment of the present utility model in detail.
A kind of metal blank locating stud, comprise location shank 3 and threaded stem 4, described threaded stem is threaded with described location shank, shank top, described location is coniform, shank bottom, described location is connected with positioning pedestal 2, excessive by chamfering 1 with shank joint, described location on described positioning pedestal.Artificially specifically make blank 5 contact and slight variations warpage through 1 place with plate locating stud, solve plate locating stud construction materials contract, problem gets stuck.Described positioning pedestal is fixed on work and inserts in 6, and threaded stem is first fixed on during work inserts, and location shank is screwed on threaded stem afterwards again, quick for installation, is convenient to change.Described chamfer angle is 30 °-45 °, and this angle is convenient to blank taking-up.
Shank top, described location is arranged with two right angle draw-in grooves.While being connected with threaded stem while installing for locating stud, spanner can be stuck on this groove, carry out fastening.
The integral type locating stud that the utility model plate locating stud is different and traditional, it is comprised of location shank and threaded stem, and processing is simple, easily assembling, manufacturing efficiency is high, saves metallic material.Even if disliking in the situation of omiting, this plate locating stud is difficult for breaking or is out of shape and is convenient to and change.
Positioning pedestal 2 place's chis are greater than location shank 3 place's sizes, make it have more stable pedestal, thereby more firmly stable, increase the service life, and excessive by chamfering 1 place.Blank 5 is along under the shank 3 places landing of location, and because positioning pedestal 2 places are excessive by chamfering 1 place with shank 3 places, location, blank 5 contacts and slight variations warpage through 1 place with plate locating stud, solves its construction materials contract, and problem gets stuck.
The utility model relates to metal sheet stamping manufacturing technology field, relates in particular to the accurate location of hot pressing die blank.The utility model is used for replacing traditional plate locating stud, has solved old-fashioned locating stud and has easily fractureed, and construction materials contract, gets stuck, the problem that the life-span is short.This simple in structure, easy for installation, with low cost, reliability is high, effectively improves the stability in blank positioning precision and product sideline, and then improves the efficiency of die debugging, guarantees mould manufacture cycle and quality, reduces manufacture cost.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
