Abstract

A one-step riveting mould for double dust-proof covers of a bearing is characterized by comprising a work bench, a guide mould pole arranged on the work bench and concentrically matched with an inner ring of the bearing, a lower punching mould concentrically sleeved on the outer part of the guide mould pole and butting against the work bench, an upper punching mould concentrically sleeved on the outer part of the guide mould pole and capable of vertically sliding along the guide mould pole, and a pressure head arranged above the upper punching mould, wherein the pressure head is used for pushing the upper punching mould so that annular riveting nozzles of the upper punching mould and the lower punching mould can simultaneously and respectively push the two dust-proof covers and rivet the two dust-proof covers into dust-proof grooves of the bearing. The double dust-proof covers are uniformly stressed and simultaneously riveted on the bearing in one step, and the riveting efficiency is improved by more than 60%.

Description

Riveting die of a kind of bearing double-side dustproof lid

Technical field:

The utility model relates to riveting die of a kind of bearing double-side dustproof lid.

Background technique:

Band dust cover type stuffing box bearing is widely used in many dirt in various machinery supports, many befouling environment, or according to the different application operating mode at the inner pre-special lubricating grease of filling of bearing and prevent that filling out in advance seborrhea goes out.The bearing two sides is with dust cover, and dust cover is fixed by special riveting mould and bearing outer ring.

In prior art, the common corresponding riveted in the left and right sides of two sides band dust cover type stuffing box bearing has left and right two dust covers, its concrete technique for riveting comprises following two kinds, mode one: riveting die is comprised of upper stamping die, base, axle, and the riveted step generally includes 1) lay bearing on riveting die; 2) dust cover of riveted; 3) take out bearing and upset; 4) bearing after overturning is placed on riveting die again; 5) another dust cover of riveted; 6) tear open and move bearing.Mode two: riveting die only is made of upper stamping die, during riveted, bearing is non-treats that the one side of riveting dust cover directly lies on press bench, punch die is placed in the top that bearing is treated riveting dust cover one side, after a complete dust cover of riveted of the bearing relative with punch die, upset bearing, then another dust cover of riveting.

There is following defective in the technique for riveting of aforesaid way one: bearing is twice disassemble or assemble on mould, and efficient is low.There is following defective in the technique for riveting of mode two: punch die directly is placed in the top that bearing is treated riveting dust cover one side, and mould only depends on dust cover circular arc crimping to locate, and is prone to the phenomenons such as riveted bias, inclination; Simultaneously, bearing directly is placed on press bench, when cycle surface is protruded in the bearing inner race lower end surface, and place, outer ring vacant state, riveted process riveted power reaches inner ring raceway from outer ring raceway through rolling element, bearing is produced impact injury.

Summary of the invention:

The purpose of this utility model is to provide a kind of bearing double-side dustproof lid a riveting die, and it is simple in structure, can make two dust cover uniform stresseds and once be riveting in simultaneously on bearing, raises the efficiency more than 60%.

riveting die of a kind of bearing double-side dustproof lid, it is characterized in that: comprise worktable, be located on worktable can with the guiding module post of the concentric coupling of bearing inner race, concentric locking collar is located at the lower stamping die that the guiding module post is outer and offset with worktable, concentric locking collar is located at the guiding module post outward and can be along the upper stamping die of guiding module post up and down slippage, and the pressure head that is positioned at the stamping die top, described lower stamping die is convex is provided with an annular riveting mouth that can act on described bearing one dust cover, described upper stamping die convexes with an annular riveting mouth that can act on described another dust cover of bearing downwards, pressure head can move down and pushing tow on stamping die along the downward slippage of guiding module post, make the annular riveting mouth of stamping die and lower stamping die can be simultaneously respectively pushes against sleeve be located at two dust cover crimpings of the bearing on the guiding module post and the rivetings simultaneously of two dust covers entered in the dustproof groove of offering on bearing outer ring.

The mould structure of the utility model is simple, and its upper and lower stamping die can make two dust cover uniform stresseds and once be riveting in simultaneously in the dustproof groove of offering on bearing outer ring, need not twice disassemble or assemble, raises the efficiency more than 60%.

The utility model can improve by following scheme:

The utility model also comprises dust cover riveted depth adjustment, and this dust cover riveted depth adjustment is located on described worktable and is positioned at a side of described guiding module post and is positioned at the below of described pressure head.Height that can dust cover riveted depth adjustment according to the bearing size size adjustment is realized the restriction of upper and lower punch die riveted axial depth, the final decision dust cover riveted degree of depth.

Described dust cover riveted depth adjustment comprises an adjustment seat that offers interior threaded hole, is complementary with the adjustment seat interior threaded hole and can screws up and down the adjusting screw rod of adjusting and be located on adjustment seat and the locking nut that coordinates with adjusting screw rod along interior threaded hole.Simple in structure, easy to adjust.

Annular riveting mouth described above has the taper pushing tow face that the crimping that can make dust cover is crooked, rise outward.Simple in structure, can be fast, convenient the dust cover riveting is entered in the dustproof groove of offering on bearing outer ring.
