Definitions
- the invention relates to a tool for the mechanical processing of plates, for connecting them together (clinching or the like), pressing, punching or the like, with a stamp and a die according to the preamble of the main claim.
- the punch has a pin of smaller diameter, through which plates to be connected are deep-drawn and crushed in a blind hole of a die, in order to establish a firm connection between the To achieve plates.
- Other generic methods are also known, in which tools consisting of stamps and dies are used, which are used for pressing, stamping or the like. serve of plates, including for connecting parts to plates (DE-OS 19913695).
- the tool according to the invention with the characterizing features of the main claim has the advantage that only the part that is actually required for processing, namely the insert part, has the desired hardness and, due to its design, experiences less or no breaking stress, while the other part, namely the receiving part, according to its purpose, can consist of softer and more elastic material.
- the manufacturing effort for the tool in particular in consideration of the risk described above, is cheaper than in the comparable prior art.
- cross-sections of the punch and / or die which particularly transmit the workforce, are larger than the cross-sections which are exposed to the actual plate processing, so that in the invention advantageously larger cross-sections are used for power transmission more elastic material is available and smaller cross-sections are used for the actual panel processing, with the appropriate tool hardness.
- the invention can be used either on the stamp side or on the die side, or on both sides.
- the punch and / or die are designed to be divided transversely to the drive direction (to the working direction), in order thereby to achieve a sufficient form fit or thus a given force fit. It is not a problem here to make the surfaces of the insert part and the receiving part opposite one another in the working direction so large that there is no excessive stress, particularly on the surface of the receiving part.
- a recess for the form-fitting connection with the insert part is provided in the end face of the receiving part facing the insert part.
- this recess is a bore or the like, into which the corresponding insert part can be inserted or inserted with the end facing it.
- the edges of the insert can be chamfered or rounded in order to make insertion easier.
- the positive connection between the insert part and the receiving part is designed as a press connection, that is to say that one There is radial pressure between the inner wall of the recess and the outer surface of the insert.
- the insert part is plug-shaped and forms its bottom after it is inserted into the recess.
- This embodiment of the invention relates above all to the die, in which case the insert does not protrude from the recess, since it is only intended to form the base because of the extraordinarily high stress there.
- connection between the receiving part and insert part is designed to be twist-locked.
- This rotational locking can be achieved by simply flattening the circular cross section on which the receptacle is based.
- the side walls of the recess have a radial distance from the lateral surfaces of the stamp, the recess being designed in the radial and axial direction as a pocket opening, the side walls of which extend in the direction of movement of the stamp and, like the bottom of the recess, are adamant.
- stamp and die is known per se (EP 0215449), but with the disadvantages of the prior art mentioned at the outset.
- the tool is used to connect components, namely bolts, nuts or the like, to a plate, the tool stamp being preceded by a lost stamp which remains on the plate after processing (DE-OS 19913695).
- Figure 1 shows a partial longitudinal section through stamp, die and
- Figure 2 shows a cross section along the line II-II in Figure 1.
- the tool according to the invention with tool holders is shown in an exploded view, but without the holder of the same in the machine tool itself, two sheets 3 to be connected to one another being arranged between a punch 1 and a die 2.
- the stamp 1 is down actuates and pulls with a pin 4 arranged at its end the correspondingly loaded sections of the sheets 3 into a recess 5 of the die 2, in order to crush these deep-drawn sheet sections radially as the stroke continues, so that the deep-drawn and crushed plate sections engage behind one another , which creates a firm connection between the plates 3 by this enforcement.
- the stamp 1 is arranged via a tool holder 6 in the machine tool, not shown here, and consists of two parts, namely a receiving part 7 and an insert part 8 having the pin 4. Due to the higher stress, the insert part 8 with pin 4 has a significantly higher hardness on, as the receiving part 7, which is also less stressed due to its larger cross section, or as the tool holder 6.
- the receiving part 7 and the insert part 8 are connected to one another via a press connection 9, the upper end of the insert part 8 being in a recess 10 in the receiving part 7 is positively inserted and is suitable for absorbing high forces.
- a flattening 11, on the end section of the insert part 8 which projects into the recess 10, serves as a rotation lock between the insert part 8 and the receiving part 7.
- the die 2 which is also arranged in a tool holder 6, is formed in two parts, consisting of a receiving part 12 having the recess 5 and a plug 13 pressed into the recess 5, which has a bend on its underside for better insertion into the recess 5 14 has.
- a bevel 15 can also be provided on its upper side, so that a bead 16 which is advantageous for production is finally created.
- the remaining rest of the recess 5 serves in a known manner as a deep-drawing opening 17 of the die 2.
- the bottom of this deep-drawing opening 17 is thus formed by the plug 13, which is also an essential one has greater material hardness than the receiving part 12 of this die.
- the tool holder 6 in each case has a base part 18 connected to the machine tool, into which stamp 1 or die 2 are inserted and are held in their working position by union nuts 19 or spring plates 20 and springs 21.
