Definitions
- the present invention relates to the production sheet metal assembly points.
- the invention relates to in particular a tool for making points sheet metal assembly according to the preamble of claim 1, in which is superimposed, at least two sheets and, using a punch and a matrix, we realize simultaneously in said sheets from a face, a cavity to form, on the other side a projection, the cavity of one of the sheets receiving the projection of the other, this so-called cavity forming an enlargement in the vicinity of its bottom, while the protrusion, by creep, forms a flare fitting into the enlargement.
- Such a technique is notably described in GB Patent No. 2,189,175, which shows a tool according to the preamble of claim 1, and is known in the language commonly known as "clinching".
- One of the aims of the present invention is to remedy these various drawbacks.
- a tool for the realization sheet metal assembly points with a top tool including a punch with a blank holder and a lower tool comprising a matrix with an anvil and shells applied elastically against the side wall of the anvil and mounted sliding in opposite radial directions on a surface for guiding said lower tool against the action of means elastic, characterized in that the shells of the lower tool have an internal lateral extension which cover part of the upper surface of the anvil in the vicinity of the side wall thereof.
- a tool comprising an upper tool 1 and a lower tool 2.
- the upper tool 1 includes a shank 3 allowing to fix it to the mandrel of a jack, a shoulder 4 against which bears a blank holder 5 having a shoulder 6 cooperating with a ferrule 7. The free end of tool 1 being terminated by a punch 9.
- the tool 2 consists of a body 11 intended to be fixed on a machine and extended upwards by an anvil 12. At the base of the anvil 12 extends a ring protruding 13 which forms, on the upper face, a surface guide 14 and, on the underside, a shoulder 15.
- a sleeve 18 made of flexible and elastic material, for example rubber or plastic, this sleeve, at its lower end, have a ring 19 intended to cooperate with a groove 20 delimited by the underside of the ring 13 and the body 11 of the tool.
- the shells 16, at their upper end, have an internal lateral extension 21 which covers part of the upper surface of the anvil 12 in the vicinity of the side wall thereof. Between tool 1 and the tool 2 are inserted two sheets 22 and 23 to be assembled.
- the shells at their upper end extend, by their surface internal to the right of the side wall of the anvil.
- the blank holder blocks the two sheets against the upper free ends of shells and the punch is engaged in the thickness of said sheets so that it is formed in the top sheet a cavity which, on the face applied against the sheet, determines a projection fitting into a cavity formed in said upper sheet.
- Figures 3 and 4 show a point assembly carried out according to the prior art and the sheets have been designated by the references 22a and 23a.
- the point obtained has a flat surface 30 which corresponds to the surface anvil and which is bordered by a corresponding bead 31 to the part of the material extending beyond the anvil and delimited by the shells.
- Figures 5, 6 and 7 show a point obtained, according to the invention.
- a cavity 33 which has, in the vicinity of its bottom 34, a widening 35, while in the sheet 23 is formed a cavity 37 which determines a projection 38 whose material, by creep presents a flare 39 fitting into the widening 35.
- the extensions 21 prevent the sheet 22 from flowing along from the side edge of the anvil 12, so that a flat assembly point, corresponding to the anvil surface, and not bordered by a bead.
