Definitions

  • the invention relates to a method for stabilizing the two snap temperatures of snap elements made of bimetallic strip, in which the mechanical operations are not interrupted by the heat treatment.
  • Snap elements are stamped from Thermobimetallband and they preferably have a circular shape. However, other forms are possible and customary: e.g. Squares, rectangles, rhombuses and shapes with a tongue in the middle. When reference is made in the following specification of snap discs, all these forms may be meant.
  • Thermobimetal snap-in elements cover a wide range of applications for controlling and limiting thermal processes.
  • the two temperatures at which the curvature of the discs suddenly changes abruptly are called “lower snap temperature and upper snap temperature”.
  • the curvature is preferably in the form of a very shallow spherical cap, but other shapes are possible, e.g. that of a very flat truncated truncated cone.
  • FIG. 1 shows the relationship between temperature and curvature.
  • the temperature is plotted and on the ordinate the curvature of the domes.
  • the aging temperature which will be discussed later, is well above the upper snap temperature, but still below the temperature, which leads to a softening of the bimetal. After embossing, the snap discs still have too little thermal stability, that is, the snap temperatures change with the number of snap movements.
  • the idea of the invention is that the stamped disks are pressed flat at a high aging temperature. This process can also be repeated several times, e.g. two times to six times.
  • FIG. 2 shows such a method.
  • the lower part of the U-shaped furnace which extends over several working positions, is denoted by 1.
  • the necessary radiator has the number 2.
  • On the bottom of the U-groove slides the stamped and embossed bimetal 3. Due to the heatability of the sole of the U-groove, the thermobimetal strip 3 resting on the sole is heated rapidly to the aging temperature, ie a temperature which is above the upper snap temperature, but below the softening temperature of the bimetallic strip 3. In the groove vertically moves the pressure bar 4, which has the same size as the bottom of the furnace base.
  • the strip is pressed with a force element no.5 (pneumatic, hydraulic, eccentric or magnetic) on the embossed discs; so strong that all embossed discs, which are located in the oven, are pressed flat.
  • the pressing process with which the snap elements are pressed flat, thus takes place at a temperature of the snap elements, which is above the upper snap temperature, but below the softening temperature of the snap elements.
  • Both processes, ie heating and pressing take place in the clamping furnace 1, the process of " pressing " taking less than one to one and one-half seconds, depending on the cycle time of the automatic stamping machine, followed by a transport cycle in which the stamping strip is pulled by exactly one position
  • This cyclical process delivers an aged disc after each cycle, without it being necessary to remove the discs from the machine.
  • the discs thus remain in the machine and the thermal aging is carried out in the machine, namely in the working cycle of the machine.
  • FIG. 2 shows that the furnace U lower part and the pressure strip 4 have a tooth-shaped toothing, which engage in one another. This gearing is used to get such an intimate heat transfer from the oven to the pressure bar that a separate heating of the pressure bar is unnecessary.

Abstract

L'invention concerne un procédé pour stabiliser les deux températures momentanées d'éléments à cliquet à bilame thermique, procédé pendant lequel les opérations exécutées par des machines ne sont pas interrompues par le traitement thermique nécessaire. Selon l'invention, les éléments à cliquet matricés sont plusieurs fois emboutis sur un plan à une température de vieillissement élevée. Selon ce procédé, les éléments à cliquet restent dans l'installation automatique de production, dans laquelle ils sont ensuite usinés.
