Injection PipesAutofrettage-Machine Main Attributes 7000 bar autofrettage pressure linear pressure generation 2 x 4 injections systems manual clamping of the test items Funktion The prefilled test items are installed at the T-fittings of the terminal block in the test chamber by means of adapters. The required pressure has to be pre-adjusted by means of manually operated pressure control valve. A protection circuit is installed in the test chamber. An air driven hydraulic pump is generating the driving pressure for each pressure intensifier. The pressure holding time is variable. The Diesel injection lines which have to be autofrettated are fixed by hand.

Table for customer specific equipment Window and possible access to the working area System for development and prototype autofrettage Panel-PC network-compatible High product variability Easy access for maintenance Autofrettage system

System features The autofrettage system is used for research and development, as well as for prototype autofrettage. The product’s versatility enables autofrettage of a wide range of components. For conversion, jigs can be exchanged. The jig area can be easily accessed via a large door. A finished part can be removed and a new one inserted. Autofrettage pressure can be flexibly programmed. The control panel is located on the right hand side at an ergonomic height. All relevant data is displayed to the operator. The closing force of a clamping device is generated hydraulically and is...

Structure of the system The test system comprises two assemblies that are combined into one compact unit. The entire floor is designed as a drain pan. The pressure generation and the electro switch cabinet are installed on the left-hand side. The right-hand side is designed as a test space. The universal test piece connection is located on the lefthand side inside the chamber. An adapter can be used with this connection to allow it to accommodate the various test pieces. All operating elements are positioned ergonomically on the operator side. There is an automatic protective door installed...

Device with tension clamps included in delivery All the tension clamps are mounted to one device support plate. To allow the rail to be placed into the device, the entire device plate is moved out of the operative area. The rail can be pushed into the device's clamps lengthwise. If the device has a rail, the device supporting plate is inserted until the rail is between the centering tips. The left-hand centering tip is located directly at the outlet of the pressure intensifier which is positioned directly next to the rail. Pressure intensifier The pressure intensifier comprises a drive part...

Main tank The main tank is made of stainless steel. A sight glass allows the filling level to be checked. A level switch controls the level in the tank. If the minimum level is undercut, the system is shut down. A collection tray is mounted below the tank. This collection tray is monitored by leak sensors. In the event of a leak, the system is shut down. The pressure intensifier and the pipeline system are filled with the filling pump. This pumps the medium through a fine filter of 10 µ to ensure the purity of the testing medium. The low-pressure circuit reaches the high-pressure circuit...

Electronic and electrical system Electro-system The power electrics and the SPS are fitted in a switch cabinet with the protection class IP 65. The electro-system is designed in compliance with the current regulations and guidelines. The master switch for the system is mounted in the door of the switch cabinet. For optimized operation, the function keys, such as the Control system On / Off , Autofrettage On / Off , EMERGENCY OFF and a PC are mounted in the operating field. The power supply is connected directly in the switch cabinet. The entire electro system is secured with the required...

Operating software The operating software serves to display the autofrettage process and also acts as a user interface. It contains various forms as well as input / output templates that are used to enter parameters, machine parameters and protocol data. Also, the results of a process can be saved. The autofrettage process is depicted graphically. After the start of the program, a screen appears from which the most important components of the program can be reached. The operating elements of the software have the following functions: Pull-down menu Software with a graphic user interface is...
