Control and Optimization of Process Parameters for a Zero-error Production

Press Load Monitoring

Forming presses, also referred to as machine presses or simply as presses, are used to bring workpieces or raw materials into certain desired shapes. The force within these presses has to be applied precisely, not only for safety in operation, but also for the quality of the products. The control of the press forces is, therefore, a part of the quality control as well as the traceability of the production process and press-tool control in terms of defects.

The pressing forces, the number of strokes, and the distribution of the force on the pressing tool are the most relevant characteristic quantities for efficient press operation, whether in big sheet-metal-presses or in fast running pill-presses.

Modern and intelligent solutions from HBK help to control and optimize the process parameters for a zero-error production and predictive maintenance.

Failsafe Press Monitoring: Measurement Technology as an Efficiency Driver

Press manufacturers are confronted with increasing technological and cost pressure: Many customers demand faster and ever more precise presses. The use of measurement technology is key to improving the presses. Precise force measurement is of vital importance - for example, using the extremely space-saving and highly accurate method of force shunt measurement - as well as targeted use of intelligent measurement electronics. This enables easy and cost-effective retooling and upgrading of existing designs.

The more precisely force is applied in presses, the higher is the quality of the molded parts. Increasing their presses' accuracy is one of the most important challenges for manufacturers of presses and pressing machines. And, in addition: The market requires increasingly faster presses that, at the same time, offer higher bandwidth to increase production output in existing systems. Modern and intelligent solutions help to make machines faster, better and more efficient.

 

Key factors for the successful use of measurement equipment include, for example:

  • Reliable and precise force measurement in the press
  • Use of intelligent measurement electronics for fast and easy connection to Industrial Ethernet standards
  • Professional measurement software for controlling the monitoring of joining processes.
  •  

Modern production can no longer do without presses in a wide range of designs. Fields of application include minting presses as well as assembly presses for vehicle parts or commodities, or presses used for huge metal parts in the automotive industry.

The presses' size and conditions of use may vary, however: The forces exerted by the press, the number of strokes and the quality of the products manufactured during the pressing procedure are major characteristic quantities for all presses.

An electronic press control system acquires and monitors these machine parameters in modern pressing machines. At the same time, it identifies defective components and rejects them. It also records production and down times - an important indicator of the effectiveness in processes.

Schuler Group: Minting Press with SLB700A and MP85A

Schuler relies on the SLB700A strain transducer and the MP85A measuring amplifier to monitor the force of the pressure used for minting. Up to 800 coins are minted every minute on one press, which for a 2-euro coin means an equivalent value of 1,600 euros per minute of ‘new’ hard cash.
