Abstract
The utility model provides a cone locating pin which is composed of a body part and a plug-in part. The body part is of a cylindrical structure, the plug-in part is fixed to the middle of the upper surface of the body part and is of a conical structure, and a spherical protrusion is arranged in the position close to the top of the conical structure. The cone locating pin is simple in structure and ingenious in design, due to the special structural design of the body part and the plug-in part, the fixing effect between a male die and a female die is prominent, a gap formed in the machining process between the male die and the female die is effectively reduced, positioning is more accurate, and the cone locating pin meets the requirement for large-scale industrial production.
Description
Technical field
The utility model relates to mould manufacturing field, especially a kind of circular cone locating stud.
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.
