BIMERIC BW 4500 High-end production system for the manufacture of contact parts for industrial circuitry

BW 4500 BIMERIC Ultimate productivity and extremely short set-up times With its high-end production system BIMERIC BW 4500 Bihler can now offer users a complete system for highly efficient production of electrical contact parts. The fully automatic NC production system offers output rates up to three times as high and set-up times up to four times as fast compared with existing systems of other manufacturers. Example of a double-trap single contact The modular design of the machine means that existing progressive dies can be fully integrated. Continuous process and quality control and the...

BW 4500 BIMERIC Your one-stop shop This modular machine design is composed of standard Bihler components: the BIMERIC NC System, two SP 500 servo-driven presses as well as integrated process modules for resistance welding/soldering and thread forming. Integration of these process technologies in fully automated production sequences has always been a key area of expertise offered by Bihler. No additional interfaces for third party components are required. With Bihler you have an experienced partner for all stages of production at your side.

BW 4500 BIMERIC Minimum retooling time All NC process modules can be programmed freely. Settings can be stored in and retrieved from the superordinate machine and process control system. All process modules are positioned fully automatically. All components that need replacing (e.g. strip guides, welding electrodes, etc.) are designed for process and user-oriented handling. Any items that need replacing are available as modular sets. All integrated process modules are fitted with rapid clamping and changeover systems. Integrated monitoring of press capacity Dynamic retraction depth control...

BW 4500 Bimeric Decoupled processes Main product features Each production stage consists of a stand-alone system with NC material feed. This division avoids the problem of faults caused by upstream processes (e.g. expansion of the strip at high temperatures and oscillations) and means different production speeds can be implemented (cycle-based production e.g. thread forming). – Highly flexible stand-alone system for the production of electrical contact parts for industrial circuitry Floating locator pin for thermally induced longitudinal expansion of the punch strip after the welding...

BW 4500 Control system Welding control B 5000 Central control system The stand-alone system and all process modules are controlled via a central machine and process control unit VariControl VC 1. The control system performs all necessary tasks and functions such as: – – – – – – machine control tool control axis control monitoring functions, e.g. measuring systems, production data acquisition diagnostics and help system all parameters are assigned to the tool program Continuous process and quality control All integrated process modules are fitted with the appropriate measuring systems....

BW 4500 „Stamping“ process module / servo-driven press SP 500 Flexible integration of progressive dies The servo-driven press SP 500 was developed in close collaboration with Minster. It has freely programmable stroke and stroke position adjustment. This means that progressive dies can be integrated flexibly into the servo-driven presses. Only two values are needed for programming: stroke length and opening value at bottom dead centre. These values are stored in the tool program and are set automatically when changing tools. A dynamic retraction depth control is integrated to ensure a safe...

BW 4500 „Welding“ process module High performance and high flexibility with servo drives Contact welding devices with the new „Quickchange“ system Two process modules for resistance welding, each with one contact welding device, are integrated in the BW 4500. The modules are powered by servo drives. The combination of the cam plate and NC technology makes overlapping time/movement profiles (e.g. resistance soldering and welding using one curve) possible for the welding gun. Bihler contact welders are stand-alone systems with a modular design. They carry out all production stages, from...

BW 4500 „Thread forming“ process module High-speed thread forming Operating principle The process module is composed of three high-speed GSE KS thread forming units. Their position in relation to the component can be set individually. The GSE KS units can be programmed freely in relation to process parameters (e.g. thread size, stroke, cutting speed). This makes different pre-strokes and return stroke speeds possible, for example. The working stroke is created by the spline shaft sliding inside the hollow shaft of the servo-motor. During the feed the sleeve is pressurised with compressed...
