Abstract
Disclosed is a split combined type forming die used for manufacturing a bearing maintainer. The split combined type forming die used for manufacturing the bearing maintainer is composed of a fixed die seat (1) and column-shaped die teeth (2) in an assembling mode. A fixed mounting hole (D) is formed in the center of the fixed die seat (1). A plurality of die tooth mounting holes (U) are evenly formed on a circumference plane of the fixed mounting hole (D). Spaces among all the die tooth mounting holes (U) are larger than the spaces among the die tooth mounting holes (U). Each column-shaped die tooth (2) is a long cylinder body, the bottom surface of each column-shaped die tooth (2) is a flat bottom, the top face of each column-shaped die tooth (U) is a circular arc-shaped top, the cross-section shape of the column is identical with the die tooth mounting holes (U), and is correspondingly arranged in the die tooth mounting holes (U) of the fixed die seat (1). When the split combined type forming die used for manufacturing the bearing maintainer is practically used, two molding dies are arranged on a punch in a staggered and opposite mode, and are meshed in an opposite mode from top to bottom, are separated, and punched in a rhythmic mode to manufacture bearing maintainers. The split combined type forming die used for manufacturing the bearing maintainer is flexible in disassembly and assembly, convenient to maintain, high in equal accuracy, good in matching performance, long in service life, good in processing quality and high in efficiency.
Description
Technical field
The utility model relates to the bearing machining equipment, relates in particular to the particular manufacturing craft of processing bearing retainer.
Background technology
Bearing is a class generalization, standardized base parts and components, uses extremely extensively aspect industrial machinery, and social required quantity is very large, is used for the supporting retainer respective numbers of bearing just many.Processing bearing retainer mould used is fixed structure at present, and fixedly die holder is connected and fixed the mould tooth, and pairing is used when machining, with the workpiece punch forming.This version is used underaction, and maintenance is inconvenient, the necessary integral replacing that breaks down, and operating cost is high, and halving precision is poor, and is easy to wear, and the product of processing affects product quality and production efficiency often with teeth mark.
The utility model content
The purpose of this utility model just is to provide a kind of rational in infrastructurely, uses safety, the bearing cage particular manufacturing craft that easy to maintenance, fault is few, the life-span is long, and the Product Precision of processing is high, quality good, reduces maintenance cost, reduces operating cost, enhances productivity.
Task of the present utility model is completed like this: design and produce a kind of assembled mould of making retainer, form by fixedly die holder and column type mould tooth are equipped, fixedly die holder is oblate cylinder metal derby, the center is provided with and fixedly mounts the hole, evenly offer several mould tooth installing holes on circumferential plane around the fixed installation hole, column type mould tooth is several long column bodies, and correspondence is inserted in mould tooth installing hole, with fixedly die holder is supporting.Fixedly the inner edge of each mould tooth installing hole of die holder is in same inner ring circuferential spacing, outer rim is in same outer ring circuferential spacing, the both sides radial edges is for connecting the radioactive ray space in the center of circle, and space adjacent between each mould tooth installing hole is greater than the occupied space of mould tooth installing hole.Column type mould tooth is the long column body, and the bottom surface is flat, and end face is circular arc top, and the mould tooth installing hole of pole section shape and fixing die holder is identical, inner narrow, the outer end is wide, and two sides can coordinate with mould tooth installing hole plug-in mounting for connecting the inclined-plane of interior outer end.Fixedly the separate assembling mould of die holder and column type mould tooth composition is paired use, and two same separate assembling moulds interlock in opposite directions and are installed on punch press, involutory, separation up and down rhythmically, and bearing cage is made in punching press.In order to gain in strength, the utility model adopts carbide alloy to make, and is wear-resisting durable, prevents from bringing teeth mark to product, and halving precision is high, and crudy is good.
Manufacture experimently, test according to such scheme, prove that the utility model is easy to use, dismounting is flexible, be convenient to adjust, fault is few, and maintenance cost is low, and matching performance is good, halving precision is high, long service life can ensure the product quality of bearing cage, enhances productivity, have good economic and social benefits, reached preferably predetermined purpose.
Description of drawings
Fig. 1 is the top view of fixedly die holder 1 of the present utility model;
Fig. 2 is the structural representation of column type mould tooth 2 of the present utility model;
Fig. 3 is that the A of Fig. 1 is to the broken section structural representation of equipped column type mould tooth 2.
In figure, 1-fixedly die holder, 2-column type mould tooth; A-line of vision symbol, D-fixed installation hole, U-mould tooth installing hole.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is illustrated.
Consult Fig. 1, Fig. 2, fixedly die holder 1 is oblate cylinder metal derby, the center has fixed installation hole D, evenly offer 8 mould tooth installing hole U on periphery around fixed installation hole D, mould tooth installing hole U is the quadrangle through hole, the inner is narrow, the outer end is wide, and the inner is in the same circuferential spacing of inner ring, and decile is uniform on periphery; It is uniform that the outer end is in the same circuferential spacing decile in outer ring; Two sides are offered along the radioactive ray that connect the center of circle; Between each mould tooth installing hole U, adjacent space is slightly larger than mould tooth installing hole U.Column type mould tooth 2 is straight cylinder, and the bottom surface is the plane, and end face is arc surface, inner narrow, the outer end is wide, the top, outside is higher than the inner face top, dual-side is the hypotenuse of outer face in connecting, its cross sectional shape is identical with the mould tooth installing hole U of fixing die holder 1.
Consult Fig. 3, each column type mould tooth 2 is inserted in each corresponding mould tooth installing hole U of fixing die holder 1 and is fixed, and forms the utility model.When installing and using, by two the utility model up and down relatively staggered be installed on press machine corresponding supporting, staggered the joining in space adjacent between the column type mould tooth 2 that is inserted in relative mould of column type mould tooth 2 of each mould, by punch press drive rhythmically the up and down involutory, separate, will be installed in two workpiece raw material punch process between mould and become the shape of bearing cage.
Adopt the utility model and punch press supporting for processing bearing retainer, matching performance is good, and halving precision is high, and is wear-resistant.The utility model adopts split modular structure, and processing and fabricating is simple, and precision is high, cost is low, convenient disassembly.If in use certain column type mould tooth 2 wearing and tearing occur or is out of shape when needing repairing, as long as this column type mould tooth 2 is pulled down, change new single column type mould tooth 2 and get final product, needn't change whole mould.Easy accessibility, quick greatly reduces the mold repair cost, has extended service life, has guaranteed the crudy of bearing cage, has improved production efficiency, has bright popularizing application prospect.
