Influence of anchor stamping process on the function of pressure control valve
Koumar, František ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
The project elaborated a possible simplification of the tool which is used for stamping of the anchor of pressure control valve (PCV). PCV is manufactured at Bosch Diesel s.r.o. Jihlava. The resulting change will reduce the cost of tool production. Current tool can be manufactured only in one company in order to achieve precise dimensions. Based on the comparison of internal stamping, it obtains the dispersion of depths for further tests. Optimal a force is obtained from these tests, followed by limit sample tests. The tests show that modified tool is not suitable for stamping on the force for anchors with limited hardness. It is necessary to use a more suitable variant. A more suitable variant is stamping on the track. With this method, there will be less effect of the hardness of the anchor. The test on stamping on the track will be performed in the second half of 2020 and, if successfully validated, will be introduced into the series.
