Abstract

The invention relates to riveting and relates to tools for pressing riveting. The aim of the invention is to expand the operational capabilities and increase the service life. For this purpose, the tool for pressing rivets comprises a housing 1, in the axial hole of which a snap 2 is placed. On the side surface of the housing 1 there are made longitudinally spaced slots 3 in which a pin 4 is fixed, fixed in the snap. Grooves 5 are made at the working end of the crimp. Grooves 7 are made on the face cutting surface of the element, and figure grooves 8 are on the side surface. The rivet rod protruding from the package of parts is placed in a common groove formed by grooves 5 and 7. When the press rod moves in the direction When the rivets 2 come into contact with the package, the body 1 compresses the spring 10. The package is tensioned. Upon further movement of the body, the protrusions 9 interact with the portions of the shaped grooves 8 arranged at an angle to the longitudinal axis of the tool. The cutting element then rotates relative to the crimping 2 and cuts off the rivet rod with the edges of the grooves 5 and 7. Riveting is carried out by the working end of the crimping 2. 1-zp ff, 6 ill. (L

The invention relates to riveting, in particular, to devices used in assembly and riveting works, and can be used in various fields of engineering.

The aim of the invention is to expand the operational capabilities and increase the resource by reducing the transverse dimensions of the tool.

FIG. 1 shows the proposed tool, general, its form; in fig. 2 - view A on. one; in fig. 3 - the same, option; in fig. 4 is a section BB in FIG. 3; in fig. 5 is a sectional view BB in FIG. one; in fig. 6 is a cross-section of the FIG. one.

with respect to swage 2 and cuts off the edges of the grooves 5 and 7 of the protruding part of the rod rivet. The height of the grooves 5 of the crimp is chosen equal to the height of the rivet rod projecting from the package for the subsequent riveting. When the press rod moves upward, the spring 10 returns the tool parts to the initial position. After this package with a rivet set coaxially with the tool. During the second stroke of the press stem, the closing head of the rivet is formed. The working end of the swage 2 can be made flat (Fig. 2) or with a recess under the closing head of the rivet (Fig. 3). Tool for press riveting, content -. A resource 1 is cut on the end surface of the housing 1, in the axial hole of which a crimp 2 is placed. On the side surface of the housing there are longitudinally arranged grooves 3 in which a pin fixed in the crimp 2 is placed 4. Grooves 5 are made on the working end of the crimp 2 a cutting element in the form of a sleeve 6, on the end surface of which grooves 7 are made, and on the side surface there are figured grooves 8 having a portion parallel to the longitudinal axis of the tool, and a portion adjacent to it, angled to longitudinal axis. On the outer surface of the body 1, protrusions 9 are fixed, placed in the corresponding figured grooves 8. The cutting element is spring-loaded relative to the body 1 by the spring 10. The shank 11 of the body 1 is fixed in the press stem.

The tool works as follows.

The rivet rod protruding from the package of parts is placed in a common groove formed by the grooves 7 of the cutting element and the grooves 5 made at the working end of the crimp 2. The housing 1 compresses the spring 10 when the press shaft moves in the direction of riveting when the crimp 2 touches the package. package. With further movement of the body, the protrusions 9 interact with portions of the shaped grooves 8 arranged at an angle to the longitudinal axis of the tool. The cutting element then rotates 20

The cutting element and at the working end of the crimp are made at least four slots, which are located at angles of 5-8 ° to the longitudinal axis of the tool.

The tool will allow the riveting of single rivets and their groups in hard-to-reach places.
