Description

one

A device for pressing rivets in hard-to-reach places, containing a fixed stop for the rivet inserts, as well as a punch holder with a rivet spring punch installed therein, cooperating with a movable pusher placed in a through-hole of the punch holder with a curvilinear working surface on the end face. However, this device does not provide riveting at once with several rivets.

The purpose of the invention is to provide riveting with several rivets located in different planes of a V-shaped package being riveted and to prevent deformation of the package in the process of riveting.

For this, the fixed stop is made in the form of a housing with a cavity, while the cavity surface and the outer surface of the punch holder are made respectively along the outer and inner contours of the riveted package, and additional holes are provided in the punch holder corresponding to the number of rivets, each of which has an additional spring-loaded punch .

FIG. 1 shows the proposed device; in fig. 2 is the same; the section along A-A in FIG. one.

The device consists of a fixed housing 1 with a cavity whose surface is identical to the outer surface of the V-shaped package 2 being riveted, the inner surface of which is identical with the outer contour of the punch holder 3. In the through hole 4 of the punch holder 3 there is a movable pusher 5 having a curvilinear working surface 6 in the form cone.

The punch holder 3 has holes 7, the axes of which are arranged normally to the outer surface of the punch holder 3 and intersect with the axis of the pusher 5.

The number and location of the holes 7 corresponds to the number and location of the rivets 8 in the riveted package 2. These holes may be located in different planes. In each of the holes is located the punch 9, the spring-loaded spring 10. The ends of the punches,

in contact with the pusher, have a spherical surface.

In the holes of the riveted package, 2, put on the control rivets, set the rivets 8 and put the package in

the cavity of the fixed body 1, then the punch holder 3 with spring-loaded punches 9 installed in it is placed in a riveted bag 2. The bag 2 is pressed against the body 1 on all

the areas of riveting by external contour of punch holder 3 due to effort PI. When this, the punches 9 are located opposite the riveted rivets 8, and the movable pusher 5 is in the initial position. The pusher 5, under the action of the force P2, moves along the through-hole of the punch holder 3, acting with its taper surface 6 on the ends of the punch 9, which, moving at the guide holes 7 of the punch holder 3, rivet the rivets.

Subject invention

A device for stress riveting in hard-to-reach places, containing a fixed stop for the rivet inserts, as well as a punch holder with a rivet spring-loaded punch installed in it, which interacts with a movable pusher placed in a through-hole with a curvilinear working surface on the end, which differs in order to provide riveting with several rivets located in different planes of a V-shaped package being riveted and to avoid deformation of the package in the essays riveting fixed stop formed

in the form of a housing with a cavity, the cavity surface and the outer surface of the punch holder are respectively provided along the outer and inner contours of the riveted package, and additional holes are provided in the punch holder corresponding to the number of rivets, each of which has an additional spring-loaded punch.
