Definitions
- the invention relates to a tool for setting full-punch rivets, with a hold-down for tempering the joining parts, in particular of sheets, one in one Cylinder of the hold-down axially movably guided and with a force can be applied riveting and a tamping opposite Die with a raised portion on a section of her riveting die facing End face.
- a tool for setting from semi-tubular rivets with a hold-down known, for toughening of sheets of different thickness, one in a cylinder of the Hold-down axially movable guided and acted upon by a force Riveting punch and a stencil opposite the holding down with an elevation on a portion of its rivet punch facing end face, wherein the end face of the die radially outside the elevation in sections is divided, namely an inner spine portion with the survey and an outer annular die section, and the individual sections the end face depending on the penetration depth of Halbhohlniets in the Sheets or of the force exerted by the riveting punch on the half - tubular rivet, in axial direction are mutually displaceable.
- the problem to be solved is, in full rivets at the beginning of the riveting process the emergence of deformations of the die-side sheet in the vicinity of Elevation of the matrix by concurrent concern of all sections of the matrix on Prevent the die-side sheet metal and then as the riveting process progresses a complete filling of the annular groove in the solid rivet by a retreat to guarantee the outer surface sections.
- the educate known tools so that the above-described defects do not adjust at the finished rivet connection.
- the tools should be simple, be uncomplicated and inexpensive.
- this object is achieved by that the end face of the die radially divided outside the elevation into sections is and the individual sections of the end face depending on the penetration depth of the solid rivet in the joining parts or of the force that the riveting punch on the rivet exerts, are mutually displaceable in the axial direction.
- Another advantage of the development according to the invention is that the According to the prior art required particularly high rigidity of the joining device no longer required to the same extent. Because the improved riveting tools a continuous flow and joining of the to be joined together Parts can cause a particularly high rigidity of the joining devices largely dispensed with what makes the tools more universal.
- the force under which the elevation of the face surrounding sections of the end face relative to the survey axially displaceable are, depending on the penetration depth of the solid rivet in the sheets to be joined generated by the force of a prestressed spring.
- This is a passive control of the axial movement of the surface portions of the die.
- a Such control is preferably applied when a simple and steadily increasing Force-displacement curve for the joining process gives a good result.
- mechanical elements e.g. Plate, screw or plastic edem a simple control can be realized.
- Position and shape of the characteristic curve within the tool by the stiffness and the preload given the springs.
- the pressure medium source is a known per se Hydraulic unit used, which has an adjustable pressure relief valve having.
- the tool according to the invention is designed such that for setting a rivet concentric the annular elevation of the end face of the die surrounding portions of this end face relative to the annular elevation are configured axially displaceable.
- this end face is so designed that that, the hump-shaped elevation having surface section the end face opposite him concentrically surrounding outer sections the end face of the die is axially displaceable.
- variable force-distance curves from the outside adjust, i. freely program.
- programmable controllers to adjust the characteristic of the known electro-hydraulic Servo valves.
- the strength of the riveted joint in particular the dynamic strength, can be significantly improved with a variable characteristic and in some applications can only be achieved in this way.
- the cutting process can be clean Cutting surface in the punched hole and with respect to the bias state after the Rivets are positively influenced.
- These important parameters are dependent on increasing wear of the cutting edge of the die.
- the wear of this Cutting edge is compensated by the axial height of the annular Elevation of the cutting edge of the die increases with progressive wear.
- This setting can be made continuously and externally. in the The simplest case reduces the volume of the hydraulic pressure medium when the outer female part is designed as a piston.
- the left half of Figure 1 illustrates the setting of a solid rivet 1 with conventional Tools dar.
- the sheets 2 and 3 with the help of rivet 1 with each other get connected.
- the sheets 2 and 3 are under the pressure of a hold-down 20 biased on the end face 21 of a die 4.
- the end face 21 has an annular elevation 5, the inner diameter 22 is so large that the shaft 23 of the solid rivet 1 in compliance with a predetermined cutting game fits.
- the hold-down 20 has a cylinder 24 in which the riveting punch 25 is guided in the axial direction 26 movable. Under the power of the riveting stamp 25 the solid rivet 1 is punched through the sheets 2 and 3, which thereby in the deform in the left half of Figure 1 shown.
- the end face 21 of the die 27 divided into sections 5 and 29.
- the annular elevation 5 of Figure 2 forms the end-side conclusion of a hollow punch 11, which with the die housing 28 is firmly connected.
- a punch member 9 in the axial direction 26 is movable stored in the female housing 28, which in the manner of a Cylinder is formed.
- the punch member 9 surrounds the hollow ram 11 concentrically.
- the face 29 of the punch member 9 and the annular elevation 5 of the hollow punch 11 together form the closed end face 21 of the die 27.
- closed End face 21 is the punch member 9 at an upper stop 10 of the die 27.
- the punch member 9 hits a lower stop 12 on.
- the die 27 shown in FIG. 2 has a venting bore 39.
