Abstract
A crimping system of a fastening component onto a support, including a crimping tool comprising a housing and a traction rod configured to cooperate with the fastening component so as to deform the fastening component when a translation of the traction rod takes place, a fluid source connected to the housing to supply a fluid under pressure to move the traction rod, a sensor to measure the movements of the traction rod, a detector to provide a pressurisation information of the fluid in the housing, and a control unit configured to record a curve of the measured movements and the pressurisation information of the fluid in the housing.

A crimping system for crimping a fastening component on a support, comprising:
- a crimping tool comprising a housing and a traction rod configured to cooperate with the fastening component so as to deform the fastening component when a translation of the traction rod takes place in the housing and along a longitudinal axis of the crimping tool;
- a fluid source connected to the housing to supply a fluid under pressure to the housing to move the traction rod;
- a sensor configured to measure the movements of the traction rod;
- a detector configured to provide a pressurisation information of the fluid in the housing;
- and
- a control unit coupled to the sensor for receiving the movement measurements and coupled to the detector for receiving the pressurisation information, the control unit being configured to record a curve of the measured movements and the pressurisation information of the fluid in the housing when the translation of the traction rod takes place,
- wherein the control unit is coupled to the fluid source and configured to stop the fluid source when:
- a measurement of the movement of the traction rod is strictly positive and the pressurisation information is zero,
- a measurement of the movement of the traction rod is zero and the pressurisation information is strictly positive,
- a measurement of the movement of the traction rod is higher than a maximum threshold, or
- a maximum value of the measurements of the movement of the traction rod is lower than a minimum movement threshold or higher than a maximum movement threshold.
A method for crimping a fastening component on a support, comprising a crimping tool having a housing and a traction rod configured to cooperate with the fastening component so as to deform the fastening component when a translation of the traction rod takes place in the housing and along a longitudinal axis of the crimping tool, the method comprising the following steps:
- supplying a fluid under pressure in the housing to move the traction rod;
- measuring the movements of the traction rod;
- detecting a pressurisation of the fluid in the housing;
- and
- recording a curve of the measured movements and a fluid pressurisation information in the housing when the translation of the traction rod takes place,
- the method further comprising a source to supply the fluid and a stopping step of the fluid source when:
- a measurement of the movement of the traction rod is strictly positive and the pressurisation information is zero,
- a measurement of the movement of the traction rod is zero and the pressurisation information is strictly positive,
- a measurement of the movement of the traction rod is higher than a maximum threshold, or
- a maximum value of the measurements of the movement of the traction rod is lower than a minimum movement threshold or higher than a maximum movement threshold.
