Description

one

The invention relates to devices for pressing riveting, in particular, assemblies in assembly devices having limited approaches to the closing head of the rivet and requiring increased pre-compression of the riveted package.

Known manual hydraulic rivet press type vise,. containing cantilever fixed and movable stops and swage with a shank on a movable stop 1}.

However, the known press does not provide high-quality riveting, since it does not compress the riveted package in hard-to-reach places, for example, an U-shaped package.

The purpose of the invention is to improve the quality of riveting in hard to reach places.

The goal is achieved by the fact that manual hydraulic -: a rigid riveting press of the type of vice, containing cantilever fixed and movable stops rigidly connected to the rod of the power cylinder, as well as coaxially positioned support on

5 fixed stop and crimping with a shank on a movable stop, provided with a spring-loaded fork-clamp mounted on the shank of the crimp, while the crimp and console of the movable stop are located in the fork jaw.

In this case, the console of the movable stop, the fork-clamping pharynx and crimping are made rectangular in shape.

Claims (2)

Manual hydraulic riveting press of the type of vice, contains cantilever fixed stop 1 with support and movable stop 2 with coaxially located on it swage 3 with the shank 4 and the package clamp in the form of a clamp-clamp, cup springs 6 and an adjustable nut 7. Fork-clamp 5 covers the crimp and the end of the movable stop 2, while the jaw of the fork-clamp, the crimp and the end of the stop are made rectangular in shape. The movable stop is rigidly connected with the rod 8 of the piston 9 of the power cylinder 10, the piston rod is spring-loaded with a spring 11 relative to the cover 12 of the fixed stop. The press works as follows. The press is set along the rivet axis 13 of the P-shaped I package. When the control button of the pneumohydraulic multiplier (not shown) is pressed, the working medium (oil) enters the cylinder 10, and the piston 9 and the rod 8 with the stop 2, crimp 3 and the forging clip 5 moves to the left, compressing the return spring 11. The clamp 5 rests against the riveted bag W, compressing it with a predetermined force of the cup springs 6 and stops. Further movement of the rod 8 with the support 2 leads first to further compression of the package and then to form the closing head of the rivet by pressing 3 The stroke of the rod 8 is set by the stop cap 12, providing the required height of the closing head of the rivet. The press is turned off, and the pressure of the working medium (oil) in the cylinder 10 drops, under the action of the return spring 11, the rod 8 and the piston 9, as well as under the action of the Belleville springs, the package pressure returns to its original position (Fig. 1). The invention provides high-quality riveting by compressing the bag when riveting in a hard-to-reach place. Claim 1. Hand-held hydraulic riveting press comprising a cantilever fixed stop and a movable stop rigidly connected to the ram of the power cylinder, as well as coaxially arranged support on the fixed stop and crimping with the shank on the movable stop, characterized in that riveting in hard-to-reach places, it is equipped with a spring-loaded clamp-clamp mounted on the crimping shank, while crimping. and the console of the movable stop are located in the throat of the clamp-clamp. . 2.Press according to claim 1, characterized in that the console of the movable support, the jaw of the forks-clamping and crimping are made rectangular.
