Abstract
The utility model provides a cylindrical locating pin which is composed of a main component and an inserting component. The main component is of a circular boss structure. The inserting component is fixed to the middle of the upper surface of the main component and is of a cylindrical structure. Semicircular protrusions are arranged on the outer surface close to the top of the cylindrical structure. The inserting component is communicated with the middle of the main component and a pin hole is formed. The cylindrical locating pin is simple in structure and ingenious in design, the main component and the inserting component are designed into the special structures, so that the fixing effect between a male die and a female die is remarkable, accurate locating is conducted in a pre-machining process, a gap and relative displacement which are generated between the male die and the female die in the machining process are effectively reduced, and the cylindrical locating pin can meet the requirements for large-scale industrial production.
Description
Technical field
The utility model relates to mould manufacturing field, especially a kind of cylindrical positioning pins.
Background technique
Locating stud is in the mould consisting of two-part or more parts, the adjacent two-part of mould are accurately located and the pin of design, visible, locating stud plays the role of positioning, mould must just can be made perfect product by accurate synchronization when closure, and locating stud can allow upper and lower two molds play the effect of accurate location.
In Design of Dies and manufacture, locating stud is one of modal part, and because it is only for the location between part, therefore, few people can give it and too much pay close attention to.
In Cold Press Working, the dimensional accuracy of blanking part depends on the size of punch-die working portion, and the dimension difference between them forms blanking die gap.Gap is the important technical parameter of Stamping Die Design, and its size has a great impact tools such as blanking part cross section quality, blanking force, die lifes.Excessive gap, stamping-out there will be punching burr; Gap is too small, and section can produce secondary slight crack, occurs extruding burr, all make the cross section quality after stamping-out undesirable, and reasonable clearance not only contributes to the raising of stamping-out cross section quality, also contributes to the raising of die life.
In manufacturing process, according to the different gap assured plan adopting in Design of Dies, correspondingly take different gap equipment adjustment methods, at present, normal use have equipment adjustment methods such as pad method, light transmission method, method of measurement, copper facing (zinc) method, coating, technique allowance, positioning work piece location.
In general, the working part that punch, die are processed respectively, because the reasonable clearance of mould in theory forms, therefore, its assembling principle is to fix the working part of be difficult for adjusting, and guarantees that by adjusting the position that the position of another working part changes between punch-die gap is even, now, only pull tight in advance screw, not fixed locating stud.
Yet practical experience is for many years noticed those skilled in the art, if can pay close attention to targetedly locating stud, use locating stud, often can produce the special effect of getting twice the result with half the effort in Design of Dies or manufacture process.Therefore, for particular mold, design targetedly locating stud, there is very important production practices meaning.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of cylindrical positioning pins.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of cylindrical positioning pins, by main body part and insertion parts, formed, described main body part is round boss structure, described insertion parts is fixed on described main body part upper surface middle part, this insertion parts is cylindrical-shaped structure, on the outer surface near cylindrical-shaped structure top, be provided with semi-cylindrical hill, described insertion parts and main body part middle part are communicated with and form pin-and-hole.
Preferably, above-mentioned cylindrical positioning pins, the quantity of described semi-cylindrical hill is 3.
Preferably, above-mentioned cylindrical positioning pins, is carved with the texture for increasing friction force on the outer surface of described main body part.

Accompanying drawing explanation
Fig. 1 is the structural representation of cylindrical positioning pins described in the utility model.
In figure: 1-main body part 2-insertion parts 3-semi-cylindrical hill 4-pin-and-hole
Embodiment
For further illustrating the utility model, now coordinate accompanying drawing to be described in detail:
As shown in Figure 1, described cylindrical positioning pins, by the main body part 1 of On The Quality of Bearing Steels and the insertion parts 2 of On The Quality of Bearing Steels, formed, described main body part 1 is round boss structure, on the outer surface of this main body part 1, be carved with the texture for increasing friction force, described insertion parts 2 is fixed on described main body part 1 upper surface middle part, this insertion parts 2 is cylindrical-shaped structure, on the outer surface near cylindrical-shaped structure top, be evenly provided with 3 semi-cylindrical hills 3, described insertion parts 2 and main body part 1 middle part are communicated with and form cross section is circular pin-and-hole 4.
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.
