EXPERIMENTAL DETERMINATION OF ENERGY REQUIRED FOR SEPARATION OF METAL PARTS FROM SPRUES

Abstract

Experimental determination of the energy and the number of impact interactions with the solid supporting surface of the castings of the «zipper» lock necessary to separate parts from the gate. Getting the corresponding calculated dependencies. Experimental modeling of impact interaction of metal parts of the “zipper” lock with the surface of the working capacity by falling castings of parts from different heights with their further collision with the supporting surface. Based on the conducted experimental study, mathematical dependences are obtained that allow one to evaluate the effect of changes in mechanical energy on the intensity of separation of metal parts of the lightning lock from the gate. In particular, it was found that with an increase in mechanical energy during the fall of castings, the intensity of separation of metal parts from gates increases significantly. The relationship between the kinetic energy needed to separate the parts of the castings of the “zipper” lock at the moment of collision with a solid surface and the total cross-sectional area of the gating system is established. The relationship between the number of shock interactions of castings of the “zipper” lock with a solid surface, necessary for separating parts, the interaction energy and the casting parameters, is determined. The obtained mathematical dependences for calculating the number of shock interactions of castings of the “zipper” lock necessary to separate all parts from the gate system of the corresponding type when falling from any chosen height. These dependencies can be used to carry out further research, in particular, to rationally determine the time spent on performing these technological operations.
