Description

High-pressure spring type press-fitting rubber shock absorber die

Technical Field

The invention relates to the technical field of automobile manufacturing, in particular to a high-pressure spring type press-fitting rubber shock absorber die.

Background

The traditional press fitting mold comprises a pressing mold base, a positioning core shaft, a pressing head, an upper guide pillar, a spring, a lower guide pillar, a positioning sleeve, a pressing plate and the like. The press-fitting die is well fixed on a hydraulic press, a hub and a belt pulley of the rubber shock absorber are firstly placed in a positioning mandrel and a cavity of a die base, then a positioning sleeve and a pressing plate are sleeved on the hub, finally a bolt is manually tightened, and the hub and the positioning sleeve are guaranteed to be pressed through the torque of the bolt. Then the rubber ring is sleeved on the positioning sleeve, the pneumatic hydraulic press moves downwards, the press fitting mold is closed, and the rubber ring is pushed into a gap between the hub and the belt pulley through the upper guide post to complete press fitting. After the press mounting is finished, the press mounting die ascends, the bolt is loosened, the positioning sleeve and the pressing plate are dismounted, the rubber shock absorber is taken out, and the next cycle is started.

Because the traditional process is tedious, the efficiency is low, and the labor intensity is high. Fatigue occurs after long-time manual operation, so that bolts are not tightened, and the torque is insufficient; the hub is axially and relatively displaced in the press-fitting process, and finally the rubber ring cannot be pressed in or even scrapped, so that the product is unqualified; the product consistency is poor.

Disclosure of Invention

The invention aims to provide a high-pressure spring type press-fitting rubber shock absorber die.

In order to achieve the purpose, the invention adopts the following technical scheme: a high-pressure spring type press-fitting rubber shock absorber die comprises a pressure head (1), an upper guide post (2), a first spring (3), a lower guide post (4), a guide sleeve (5), a film pressing base (6), a bolt (7), a first screw (8), a second screw (9), a second spring (10), a belt pulley (11), a rubber ring (12), a hub (13) and a guide mandrel (14);

the pressure head (1) is connected with the upper guide pillar (2) through the bolt (7); the lower guide post (4) is connected with the first screw (8), and the middle part of the lower guide post moves up and down on the excircle of the upper guide post (2) by filling the first spring (3); the guide sleeve (5) is connected with the second screw (9), and the middle part of the guide sleeve moves up and down in the inner cavity of the upper guide post (2) by filling the second spring (10); the guide mandrel (14) is connected with the film pressing base (6) through a bolt, the guide mandrel (14) is used for fixing a pressed workpiece hub (13), and the film pressing base (6) is used for fixing a pressed workpiece belt pulley (11); the rubber ring (12) is fixed in a gap between the guide sleeve (5) and the lower guide post (4), and the rubber ring (12) is pushed out and extruded into a gap between the hub (13) and the belt pulley (11) by applying pressure.

The invention has the beneficial effects that: the device changes the method of locking the positioning sleeve by using the bolt into the guide sleeve, and the guide sleeve is popped out by the strong spring, so that the processes of manually filling the positioning sleeve and loosening and tightening the bolt are omitted, the guide sleeve can only move up and down in the cavity of the upper guide pillar during press fitting, and the hub is firmly supported by the guide sleeve popped out by the strong spring, so that the hub cannot generate axial displacement, the product consistency is ensured, the labor intensity is reduced, and the working efficiency is improved. Meanwhile, the rubber ring can be sleeved on the guide sleeve popped up by the high-pressure spring, so that the working efficiency is improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

As shown in fig. 2-3, a high-pressure spring type press-fitting rubber damper mold comprises a press head 1, an upper guide post 2, a first spring 3, a lower guide post 4, a guide sleeve 5, a film pressing base 6, a bolt 7, a first screw 8, a second screw 9, a second spring 10, a belt pulley 11, a rubber ring 12, a hub 13 and a guide mandrel 14.

The pressure head 1 is connected with the upper guide post 2 through a bolt 7. The lower guide post 4 is connected with a first screw 8, and the middle part of the lower guide post moves up and down by filling a first spring 3 on the excircle of the upper guide post 2. The guide sleeve 5 is connected with a second screw 9, and the middle part of the guide sleeve moves up and down in the inner cavity of the upper guide post 2 by filling a second spring 10. The guide mandrel 14 is connected with the film pressing base 6 through bolts, the guide mandrel 14 fixes the pressed workpiece hub 13, and the film pressing base 6 fixes the pressed workpiece belt pulley 11. The rubber ring 12 is fixed in the gap between the guide sleeve 5 and the lower guide post 4, and by applying pressure, the rubber ring 12 is pushed out and pressed into the gap between the hub 13 and the pulley 11.
