Abstract
The utility model discloses a bearing shield assembly mold, which is composed of a cylindrical handle (1), a cake punch (3) and a bolt (5). A buffer block (2) is arranged between the cylindrical handle (1) and the cake punch (3), and a stamping surface (4) of the cake punch (3) is made into an arc surface with the same radius of the pressed arc surface of a shield. The bearing shield assembly mold can effectively solve the shortcomings of excessive stamping and not-in-place shielding of the original shield assembly mold and the uneven pressure of the shield, improve the assembly qualified rate of the shield, reduce the manufacturing cost of a bearing and improve the economic benefits.
Description
Technical field
The utility model relates to a kind of bearing dustproof cover assembly tool, specifically, is a kind of bearing dustproof cover assembling mould.
Technical background
As everyone knows, the bearing of band dust cover mostly is ball bearing, during manufacturing, generally to the dust cover groove be set at the two ends of the internal diameter of bearing outside collar, then dust cover is put into groove, dust cover assembling mould with special use is stamped into dust cover in the dust cover groove on punch press, thereby fixes dust cover.Original dust cover assembling mould is the rigidity contact, because the size of dust cover, dust cover groove and bearing height all exists form and position tolerance, and punching stroke is fixed, for the big and dust cover tolerance of dust cover groove and bearing height stack tolerance hour, cause punching press not in place easily, dust cover is difficult for fixing, and very easily causes dust cover to come off during use; When big, easily cause punching press excessive for the less and dust cover tolerance of dust cover groove and bearing height stack tolerance again, cause the dust cover distortion; Original in addition dust cover assembling die stamping face is the inclined-plane, and the compression face of dust cover is an arc surface, and stamping surface is the line contact with contacting of dust cover, the dust cover pressurized is inhomogeneous during punching press, also cause the dust cover distortion easily, thereby make that dust cover assembling up-to-standard rate is low, increased manufacture cost.
Summary of the invention:
The purpose of this utility model provides a kind of bearing dustproof cover assembling mould, can solve effectively that original dust cover assembling die stamping is excessive, punching press is not in place and the uneven defective of dust cover pressurized, improve dust cover assembling up-to-standard rate, reduce the bearing manufacture cost, increase economic efficiency.
The purpose of this utility model is achieved through the following technical solutions: this bearing dustproof cover assembling mould is made up of cylindrical handle, cake formula drift and bolt, it is characterized in that: between said round handle and cake formula drift, be provided with a block buffering piece, the stamping surface of cake formula drift is made arc surface with dust cover pressurized arc surface same radius.
The bearing dustproof cover assembling mould of this band buffer stopper, when the punching press dust cover, punching stroke is adjusted to the best, when the big and dust cover tolerance of dust cover groove and bearing height stack tolerance hour, because buffer stopper anamorphic effect, can overcome punching press defective not in place, dust cover is fixed; In like manner, when the less and dust cover tolerance of dust cover groove and bearing height stack tolerance is big, can not cause again punching press excessively and dust cover be out of shape; Stamping surface is an arc surface, makes dust cover stressed more even, effectively prevents the dust cover distortion,
Description of drawings
Fig. 1 is the structural drawing of the utility model bearing dustproof cover assembling mould.
Among Fig. 1: 1, cylindrical handle, 2, buffer stopper, 3, cake formula drift, 4, stamping surface, 5, bolt.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In the embodiment shown in fig. 1, the utility model bearing dustproof cover assembling mould is made up of cylindrical handle 1, buffer stopper 2, cake formula drift 3, cylindrical handle 1 and cake formula drift 3 adopt carbon steel to make, cylindrical handle 1 one ends have a disk, the other end is made hemisphere, and the disk end has a screw; Buffer stopper 2 is a cake formula structure, links to each other with the disk of cylindrical handle 1, make of ebonite, and highly be 20mm-30mm, there is a through hole centre, and buffer stopper 2 diameters are identical with the disk diameter of cylindrical handle 1; Cake formula drift 3 is a cake structure, one side has a positioning round table, in the same side, near cake formula drift 3 circumferential edges places, a ring projection is arranged, and the inner side surface of projection is the inclined-plane, and the outer side surface of projection is a circular arc stamping surface 4, there is a stepped shape through hole at cake formula drift 3 centers, successively cake formula drift 3, buffer stopper 2 and cylindrical handle 1 are fixed together with bolt 5.
The assembling of the shielded bearing of a model will have a dust cover assembling mould.For the 6219K-Z shielded bearing, its dust cover assembling mould is of a size of: cylindricality handle 1 body diameter is 30mm, and length 70mm, disk diameter are 55mm, highly is 25mm, and disk end screw is M8; Buffer stopper 2 diameters are 55mm, highly are 25mm, and the diameter of intermediate throughholes is 8.5mm; Cake formula drift 3 external diameters are 152mm, the high 10mm of positioning round table, and diameter 95mm matches with the 6219K-Z brearing bore; The ring projection height of cake formula drift 3 circumferential edges is 5mm, projection internal diameter 146mm, the inner side surface of projection is the inclined-plane, the outer side surface of projection is that radius is the circular arc stamping surface 4 of 1.0mm-1.5mm, with bolt 5 cake formula drift 3, buffer stopper 2 and cylindrical handle 1 are fixed together, just can be used for the assembling of bearing dustproof cover.
During assembling, bearing is placed on the stamping press, dust cover is placed on the bearing, again dust cover is assembled the positioning round table that mould puts and put into the bearing warp, make stamping surface 4 just in time push down the dust cover circular edges, catch cylindrical handle 1, allow the downward punching press cylindrical handle 1 of stamping press then with hand, the dust cover circular edges is out of shape downwards, is extruded into the dust cover groove and fixes dust cover.
Claims (2)
1, a kind of bearing dustproof cover assembling mould, form by cylindrical handle (1), cake formula drift (3) and bolt (5), it is characterized in that: between said cylindrical handle (1) and cake formula drift (3), be provided with a block buffering piece (2), the stamping surface (4) of cake formula drift (3) is made arc surface with dust cover pressurized arc surface same radius.
2, a kind of bearing dustproof cover assembling mould according to claim 1, it is characterized in that: said buffer stopper (2) adopts ebonite to make.
