Description

A kind of roller bearing E shape frame riveting die

Technical field

The utility model belongs to two class roller bearing E shape retainer compression moulds, is specifically related to a kind of roller bearing E shape frame riveting die.

Background technology

Cylindrical roller bearing used copper cage originally in manufacturing process, because copper material price is high recently, for reducing cost, various alternative materials are arisen at the historic moment, and as the alternative materials of E shape steel plate retainer, the use of low carbon steel plate is the most extensive.

E shape retainer is when running in bearings, and for fixing roller, it is deformed to certain position to need compressing, just can lock roller, use at first the lever manual formula, can only press two ears at every turn, fix a roller, operation is slow, and discontinuity, the roller degree of tightness is difficult to unification by operator's control, disposable diel occurs subsequently, efficient improves several times, be from top to down but be pressed into, easily scratch increases the bearing finished products operating noise.

The utility model content

The utility model has overcome the deficiency that prior art exists, and provides a kind of roller bearing that makes to be difficult for scratch, roller bearing E shape frame riveting die that operating noise is little.This mold has simple to operate, and is easy to use, thoroughly solves scratch, noise problem, improved quality and efficient, makes brandreth bearing completed products quality improve a class.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of roller bearing E shape frame riveting die, comprise main die body, base plate and drift, main die body is arranged on the base plate, be provided with the outer slide block that rises in the main die body, the outer shape of slide block and the inboard shape of E shape retainer of roller bearing of rising outward adapts, and the slide block arranged outside that rises outward has the first spring that the outer slide block that rises is resetted, rising outward, in the vertical direction has conical through-hole on the slide block, it is cylindrical that the top of drift becomes, it is conical that the bottom of drift is, lower portion of ram is complementary with the conical through-hole of the slide block that rises outward, be used for the top that fairlead that pilot punch moves up and down is arranged on main die body, the second spring that is used for drift is upwards resetted is arranged on base plate;

The arranged outside of main die body has locating ring, and the arranged outside of locating ring has discharge ring, and the discharge arm that is arranged on the base plate utilizes lever principle to drive the capable discharging of shift-in on the discharge ring.

Described drift is driven by forcing press and moves down.

The beneficial effect that the utility model compared with prior art has is: drift relies on the forcing press driving to move down in the utility model; be the outer slide block that rises of conical lower portion of ram extruding; the outer slide block that rises is expanded outwardly; the roller bearing E shape retainer that adapts with the slide block profile that rises outward is extruded moulding; after the moulding of the E of roller bearing shape retainer; remove the downward power of forcing press; drift is under the elastic force effect of the second spring; upwards reset; the operation discharge arm makes the discharge ring roller bearing E shape retainer that will process that moves up be ejected main die body; the slide block that rises outward resets under the active force of the first spring; finish a processing; repeat above-mentioned steps; can realize continuous production; the utility model E shape retainer external diameter has main die body protection; make E shape retainer integral body motionless; only have each ear stressed; thereby make the roller bearing after the assembling be difficult for scratch; operating noise is little; the utility model is simple to operate simultaneously; easy to use; thoroughly solve scratch; noise problem has improved quality and efficient, makes E shape retainer end product quality improve a class.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is structural representation of the present utility model.

Among the figure, 1 be main die body, 2 for base plate, 3 for the slide block that rises outward, 4 for discharge arm, 5 for drift, 6 for fairlead, 7 be that the second spring, 8 is the first spring for locating ring, 9 is discharge ring, 10.

The specific embodiment

As shown in Figure 1, a kind of roller bearing E of the utility model shape frame riveting die, comprise main die body 1, base plate 2 and drift 5, main die body 1 is arranged on the base plate 2, be provided with the outer slide block 3 that rises in the main die body 1, the outer shape of slide block 3 and the inboard shape of E shape retainer of roller bearing of rising outward adapts, and slide block 3 arranged outside that rise outward have the first spring 10 that the outer slide block 3 that rises is resetted, rising outward, in the vertical direction has conical through-hole on the slide block 3, it is cylindrical that the top of drift 5 becomes, it is conical that the bottom of drift 5 is, drift 5 bottoms are complementary with the conical through-hole of the slide block 3 that rises outward, be used for the top that fairlead 6 that pilot punch 5 moves up and down is arranged on main die body 1, the second spring 7 that is used for drift 5 is upwards resetted is arranged on base plate 2;

The arranged outside of main die body 1 has locating ring 8, and the arranged outside of locating ring 8 has discharge ring 9, and the discharge arm 4 that is arranged on the base plate 1 utilizes lever principle to drive the capable discharging of shift-in on the discharge ring 9.

Described drift 5 is driven by forcing press and moves down.

The course of work of the present utility model: the starting pressure machine drives drift 5 and moves down, insert in the conical through-hole of the outer slide block 3 that rises the bottom of drift 5, the outer slide block 3 that rises is squeezed outwards to be opened, make E shape retainer be subjected to molded, after to be formed, remove the downward active force of forcing press, drift 5 upwards resets under the active force of the second spring 7, pull discharge arm 4 and discharge ring 9 is moved up the E shape retainer after the moulding is ejected from main die body 1, the slide block 3 that rises outward resets under the active force of the first spring 10.

Fairlead 6 mainly play the guiding role to drift 5 in the utility model, and locating ring 8 is guaranteed the accurate positioning of E shape retainer.

The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
