Abstract
The invention provides a cylindrical locating pin. The cylindrical locating pin consists of a main body component and an inserting component, wherein the main body component is of an elliptic columnar structure; lug bosses are symmetrically arranged at the bottom edge of the main body component; the inserting component is fixed at the middle part of the upper surface of the main body component; the inserting component is communicated with the middle part of the main body component and a pinhole is formed; the cylindrical locating pin is simple in structure, ingenious in design and capable of having a remarkable fixation effect on a convex die and a concave die due to the design of the special structure of the main body component and the inserting component; precise location can be performed during a pre-machining process, so that a gap formed during a machining process of the convex die and the concave die is effectively reduced; meanwhile, a good anti-shearing effect is achieved, so the cylindrical locating pin is suitable for the requirements of large-scale industrial production.
Description
Technical field
The present invention relates to mould manufacturing field, especially a kind of cylindrical positioning pins.
Background technique
Locating stud is in the mould be made up of two-part or more part, the adjacent two-part of mould are accurately located and the pin designed, visible, locating stud plays the role of positioning, mould just must can make perfect product by accurate synchronization when closed, and locating stud can allow upper and lower two molds play the effect of accurately location.
In Mould design and manufacturing, 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 namely 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 adopted in Design of Dies, correspondingly take different gap equipment adjustment methods, at present, normal utilization has the equipment adjustment method such as pad method, light transmission method, method of measurement, copper facing (zinc) method, coating, technique allowance, positioning work piece location.
In general, to the working part that punch, die are processed respectively, because the reasonable clearance of mould in theory is formed, therefore, its assembling principle fixes the working part not easily adjusted, and ensure gap uniformity by the position changed between punch-die, the position adjusting another working part, now, only pull tight screw in advance, not fixed locating stud.
But practical experience for many years makes those skilled in the art notice, if in Design of Dies or manufacture process, locating stud can be paid close attention to targetedly, uses locating stud, often can produce the special effect of getting twice the result with half the effort.Therefore, design locating stud targetedly for particular mold, there is very important production practices meaning.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cylindrical positioning pins.
For solving the problems of the technologies described above, technological scheme of the present invention is:
A kind of cylindrical positioning pins, be made up of main body part and insertion parts, described main body part is elliptical cylinder structure, this main body part bottom margin is arranged with boss, described insertion parts is fixed on described main body part upper surface middle part, this insertion parts be communicated with in the middle part of main body part and form pin-and-hole.
Preferably, above-mentioned cylindrical positioning pins, described insertion parts is cylindrical-shaped structure.
Preferably, above-mentioned cylindrical positioning pins, the cross section of described pin-and-hole is circular.
Preferably, above-mentioned cylindrical positioning pins, the material of described main body part and insertion parts is On The Quality of Bearing Steels.
Structure of the present invention has following beneficial effect:
Above-mentioned cylindrical positioning pins, structure is simple, design ingenious, the special construction design of main body part and insertion parts, fixed effect between punch, die is given prominence to, accurately can locate in first course of working, effectively reduce the gap formed in course of working between punch, die, play good anti-shearing effect simultaneously, be applicable to the needs of large-scale industrial production.
Accompanying drawing explanation
Fig. 1 is the structural representation of cylindrical positioning pins of the present invention;
Fig. 2 is the worm's eye view of cylindrical positioning pins of the present invention.
In figure: 1-main body part 2-boss 3-insertion parts 4-pin-and-hole
Embodiment
For further illustrating the present invention, accompanying drawing is now coordinated to be described in detail:
As depicted in figs. 1 and 2, described cylindrical positioning pins, be made up of the main body part 1 of On The Quality of Bearing Steels and the insertion parts 3 of On The Quality of Bearing Steels, described main body part 1 is elliptical cylinder structure, this main body part 1 bottom margin is arranged with boss 2, described insertion parts 3 is cylindrical-shaped structure, and this insertion parts 3 is fixed on described main body part 1 upper surface middle part, and this insertion parts 3 is circular pin-and-hole 4 with being communicated with in the middle part of main body part 1 and forming cross section.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
