Abstract

The head of a bolt is cut by means of a die (1). Deburring is carried out with an ejector pin (10) which pushes the bolt through the die (1). If the die (1) is blunt, the ejector pin (10) cannot push the bolt through the said die or can do so only with a delay and this would lead to damage to the machine when another bolt was fed in. The ejector pin (10) has a part (17) which is supported by a spring (18). The ejector pin (10) is driven by a cam. The working angle of rotation of the cam is divided into a fixed number of pulses. The correct processing time for a bolt is defined by two limiting numbers of electronic pulses which are produced by a pulse generator. The number of pulses emitted by the pulse generator during processing is compared in an electronic comparison device with the two limiting numbers. If there is a deviation, at least part of the machine is automatically switched off.
