Definitions
- the invention relates to a die for a tool set for mechanical Joining according to the preamble of claim 1.
- a tool set for producing joints is plate-shaped parts known, the first upper tool part with a Stamp and a second lower tool part having a round die.
- the female part has an anvil with an anvil body on which annular element with a head-side sliding surface and a bottom side Pad are provided.
- Single, surrounding the anvil, Ring-segment-shaped die segments have recesses for a concentric, a longitudinal movement of the die segments allowing flanges thereof to the annular member, each Matrizensegment on the head-side sliding surface under spring preload slidably supported, including an elastic means the Matrizensegmente the lateral surface of the anvil applies.
- the disadvantage here is that the die segments due to their unfavorable Ratio of height to radial extent tipping rather than tilt radial slide and thereby cant and thereby jam.
- the support of the die segments on the anvil body decreases in size the longitudinal outward movement, since the die segments from the Lead at least partially run out.
- An increased Risk of breakage of Matrizengrund stressess is the result.
- the lifetimes of a such matrix are therefore low.
- the annular element requires the anvil body an increased height, whereby the accessibility to Joint in shaft-like components is severely limited.
- WO 01/36124 A2 is a generic tool set for manufacturing known from joints on plate-shaped parts, comprising a round die. Individual, the anvil surrounding ring-shaped die segments are against a spring bias to the outside displaced on a support surface arranged. The radial displaceability of the die segments to the outside becomes limited by a the support surface enclosing stop, the a Matrizenhülse is formed. The stop is also used to an axial Movement of the die segments in their displacement to the outside prevent what this projecting guides, the in Engage undercuts of the die segments. The disadvantage is again, in that the die segments tilt relative to the projecting guides and thereby jam.
- a round die includes.
- the die has four die segments, that of a housing are surrounded.
- the housing is equipped with oblong holes, with between two slots each pin extend into the interior of the housing. These pins engage in grooves formed on the die segments.
- edges of the die segments in the slots of the Matrizengephaseuses movable wherein the engaging in the die segments Counteract pins of a rotational movement of the die segments.
- the object of the invention is therefore to provide a die for a tool set for mechanical joining according to the preamble of claim 1 to provide has a long service life and is compact in construction.
- a die for a tool set for mechanical joining created, the die segments each have a guideway in the Assigning template sleeve.
- the die segments are supported at their radially to Anvil directed displacement on a support surface of the Matrizengrund stressess and receive an additional direct guide through the Die segment sections which slideably engage the die sleeve.
- Such a die is in terms of die height and die diameter built compact and has improved guiding properties for the sliding die segments on.
- the die sleeve preferably has the die sleeve wall completely piercing breakthroughs, in which the die segments with one each Intervene extension.
- the radial displacement of the die segments lies within the segment guides and thus does not lead to increased expansion of the tool in the radial direction. It is also advantageous that dirt can be discharged from the die, which further their service life be improved.
- the segment guides in the die sleeve form closed guides that allowing sliding of the die segments radially to the anvil and at the same time limit axial displacement of the same.
- the in the art required undercuts on the die segments for securing the same against axial displacement of the support surface can be omitted.
- the Matrizensegmente and thus the entire matrix can consequently a lesser have axial height. That reduced compared to the prior art Ratio of axial to radial extent of Matrizensegmente leads at the same time to a greater stability against tilting during the radial Shifting.
- the die is round and has a die sleeve with in Circumferentially extending and on a contour line opposite the Support surface arranged guideways.
- the die segments are then preferably formed as annular sections, preferably at least three Matrizensegmente are provided. Particularly preferred are four to six Matrizensegmente provided to minimize the spatial extent of joints between the die segments in the expanded state to reach.
- the spring bias is by an elastic ring, the in particular may be a metal spring exerted.
- the die segments each have a in Having circumferentially extending groove.
- Figs. 1 to 5 show a first embodiment of a die 1 for a Tool set for the mechanical joining of sheet metal on one another by forming with at least one stamp (not shown) and a Die 1.
- the die 1 defines a cavity 2 (see Fig. 4) in the inside is added.
- the die 1 comprises for this purpose an anvil 3 with a head-side Anvil surface against which the stamp is movable.
- At the anvil are 3 individual cavity segments 9 delimiting the cavity 2 in the circumferential direction. 9 provided that the feed of the punch in the direction of the anvil 3 a Evasive movement transverse to an axial extension of the anvil 3 and thus Run transversely to the punch feed direction.
- the die 1 comprises to preferably designed as a straight circular cylinder anvil 3, the a Matrizengrund stresses 7 is formed.
- MatrizengrundMech 7 On the Matrizen groundMech 7 is concentric with the anvil 3 is a flat Provided support surface 4, opposite to the anvil 3 with a selectable height protrudes, and which forms a sliding surface for the die segments 9. Die Support surface 4 is preferably perpendicular to an outer circumferential surface of the Anvil 3 arranged. The support surface 4 is preferably on the MatrizengroundMech 7 provided with an arranged in the center anvil 3.
- the at Advance of the punch in the direction of the anvil 3 an evasive movement across to perform the punch feed direction, including the Matrizensegmente 9 against a spring preload are displaced outwards. After spreading the Matrizensegmente 9 then closes the die 1 then again independently.
- a spring element 5 is an annular spring. Versus which are acting in the direction of the anvil 3 spring force of the spring element 5 the die segments 9 displaced outwards.
- the die 1 further comprises a die sleeve 8, which is the Matrizengrund stresses 7 circumferentially encased.
- the die sleeve 8 has in the circumferential direction, a Division in die segments 9 following, individual segment guides 10, the through the die sleeve 8 extending guideways 11 form and in which the die segments 9 as formed with an extension 12 sliders after guided on the outside are displaced fixed.
- the ring part surfaces 13 limit the cavity 2 on the anvil 3 and are formed on a the Anvil 3 facing head 15 of the die segment 9, on which also the Nut 6 is provided for the spring element 5. From the head 15 extends the respective extension 12 of a die segment 9.
- Each die segment 9 of header 15 and extension 12 preferably has a flat bottom surface 14 (see Fig. 5), with which the die segment 9 slidably rests on the support surface 4 and with an anvil. 3 remote projection 12 protrudes into a respective segment guide 10.
- a die segment 9 in the die sleeve 8 engages the Extension 12 of the die segment 9 as a slider in a closed Guide trained segment guide 10 a.
- the segment guides 10 penetrate the female sleeve 8 completely.
- the guideways 11 of Segment guides 10 and the boundary surfaces of the extensions 12 are according to Art matched by sliding guides.
- the extensions 12 include next to the bottom surface 14 of the bottom surface 14 opposite upper side Guide surface 18.
- the bottom surface 14 of a die segment 9 facing surface of the guideway 11 preferably remains out of engagement with the die segment 9. The sliding movement of the die segment 9 with his Bottom surface 14 of the support surface 4 in the die sleeve 8 then takes place reliable on the support surface 4.
- a second embodiment shown in Fig. 6 of the die 1 is a Quick-change closure for attachment of the above-described Die shown on a die holder 19. Intended is a on the Die holder 19 radially to the die sleeve 8 arranged resilient pin 20, the can engage in a radial bore 21 of the die sleeve 8. It is then no screws to be loosened required.
