Definitions
- the invention relates to a method for the local forming of brittle material.
- the invention relates in particular, but not exclusively, to the joining of sheets by means of clinching techniques.
- Such processes are widely known.
- This technology has established itself as an economical manufacturing process in many areas, for example in vehicle construction, in air conditioning technology, in mechanical engineering when it comes to mass production.
- Such joining processes can be used with many metals and plastics. So far, however, it has not been possible to join brittle materials, such as certain aluminum alloys, with such techniques because their elasticity is not sufficient; In general, such brittle materials can only be formed without cutting in a narrow framework.
- the object of the invention is to provide a method that allows larger changes in shape of brittle materials than previously possible.
- the penetration of sheets made of brittle aluminum alloys should be made possible.
- Known clinching tools of the types mentioned initially generally comprise a die which delimits a cavity into which the sheet metal material is deformed by means of a stamp; An anvil, which forms the die base, is arranged opposite the stamp work surface.
- the sheet material is placed under pressure in that the anvil is subjected to a corresponding spring preload in the direction opposite to the working stroke of the stamp.
- clinching tools are known in which the anvil is spring-biased in the same direction.
- US-A-3,771,216 discloses such an arrangement, the anvil-spring combination serving as an ejector which is intended to detach the joint from the die.
- US-A-4,584,753 discloses a die in which the anvil protrudes spring biased over the die edge; here the cantilevered anvil stub serves as a centering element which is intended to position a pre-perforated sheet with respect to the die and with respect to the stamp. In both cases, however, the force generated by the spring is orders of magnitude lower than the forces to be applied according to the invention.
- FIG. 1 shows the position of the components (designed for simplicity with a circular cross-section) at the beginning of the joining process.
- FIG. 2 at the end of the joining process in axial section.
- An anvil 12 is slidably seated in a die 10, guided in a die bore 14.
- the upper section of the bore delimits the cavity 16 into which the material is deformed (cf. FIG. 2).
- a shoulder 18 serves as an upper stop for a collar 20 molded onto the anvil.
- Thread 22 is cut into the subsequent lower part of the die hole with a larger diameter and a lower stop 24 is screwed in.
- a strong spring, here a pressure coil spring 26, is clamped between it and the collar 20 of the anvil, which biases the anvil into its upper end position, shown in FIG. 1. It can be seen that the anvil protrudes beyond the front working surface 28 of the die and is chamfered all around before joining.
- the punch 30, driven, for example, by a hydraulic unit, first clamps the sheets 32, 34 to be joined between its working surface and the anvil, as a result of which the sheet material is subjected to a pressure load corresponding to the preload by the spring 26. During the joining, this pressure load initially increases until the anvil is pressed back into the die bore, surprisingly no material breakage occurs. Finally, the anvil sits on the lower stop and the punch pushes material into the space that is left free from the anvil chamfer, causing the stapling. It can be seen that the pressure load is effective not only before but also during enforcement.
- the die can be hinged for easier removal and can be undercut in the area of the cavity, all of which is already known in the case of joining tools, but which could also be used here advantageously.
