Electric servo-driven press-fit machine

Written by Lormac Automation on . Posted in Press fitting

Electric servo-driven press-fit machine used in an industrial vehicle component production process.The assembly machine benefits from the latest innovations offered by Lormac and includes the patented digital feedback platform.

Requirement / Press fitting of car components.

Press fitting of various components for the vehicle industry including fragile parts such as bearings. One of the constraints of this application was to provide a programmable solution capable of fast production run change-outs.

Solution / Electric servo-driven machine.

Lormac’s solution was to provide an electric press-fit machine equipped with a digital feedback platform (real-time dimension transfer).

The machine’s performance levels /

  • Positioning accuracy of 0.01 mm
  • 50 kN pressure (as standard)
  • Press-fitting pressure control (value and position)
  • Capability of handling deformable and fragile parts using reference surface transfer
  • Run of 200 mm
  • Satellite spindle drives for greater longevity
  • Automatic lubrication of the spindle.

Specialised assembly machine: sleeve crimping

Written by Lormac Automation on . Posted in Crimping, Forming, Press fitting

Specialised assembly machine designed to crimp connectors at the ends of tubes.

Requirement / To strengthen the ends of tubes.

The customer wished to attach strengthening sleeves to the ends of tubes by expansion to reinforce them.

Solution / A custom crimping machine.

The assembly machine developed by Lormac allowed the parts to loaded manually or using a robot. The strengthening sleeves were press-fitted and expanded using hydraulic power. A side-punching process was applied at the end to provide extra solidity and a good finish.

The crimping machine’s performance levels /

  • 6 second cycle time

Press fitting assembly of a water pump

Written by Lormac Automation on . Posted in Press fitting

Automated assembly line for the industrial manufacture of a water pump. The production line comprised 4 digitally-controlled press-fit machines, component distribution and loading robots and end-of-process checking systems.

Requirement / To assemble components and check products.

Assembly, press fitting and testing of a new water pump.

Solution / Automated press fitting machine.

Lormac designed an automated assembly line to assemble new products. Lormac staff used their ingenuity to create an entire automated manufacturing system including :
  • Automated distribution and loading of components
  • Design of 4 specialised electric press fitting machines and tools
  • Integration of 2 transfer robots for feeding and unloading of off-line stations
  • Addition of 2 off-line automated bolting stations
  • Insertion of 2 seal testing stations
  • Implementation of a pallet transfer conveyor
The press fitting machine uses a “gooseneck” assembly process with deformation correction and strength control.

The machine’s performance levels /

  • Capacity of each press-fit machine: 50 KN
  • Feedback platform designed and patented by Lormac
  • 9 second cycle time
  • Accuracy +/- 0.03

Further information.

Since this press fitting assembly line went into operation in 2008 total down-time amounted to less than one day, proving the reliability of this solution which was entirely designed and manufactured by Lormac. Over 7 million water pumps have been produced to date with continuous production in 3 shifts.
