Dobladoras de barra Serie Profesional de EHRT

Modelos disponibles:
EB 30 Professional, EB 40 Professional

EHRT es fabricante líder de máquinas de punzonado y doblado de material en barra (busbar / barras de distribución) desde hace más de 50 años. Las dobladoras EHRT cuentan con tecnología patentada única de doblez con compensación por recuperación que garantiza una precisión nunca antes vista en materiales planos, mientras que los sistemas de corte y punzonado EHRT son rápidos y eficientes, logrando hasta 200 golpes de punzonado por minuto.

Professional

Las dobladoras de barras de cobre EHRT de la línea Professional están diseñadas para altas cargas de producción y se caracterizan por contar con una vida útil y presición incomparables. Las máquinas de la línea Professional son extremadamente poderosas y capaces de doblar piezas individuales y pequeños lotes con la misma precisión y eficiencia de las partes fabricadas en serie.

Modelos de 30 o 40 toneladas

Capacidad de doblez desde 160 x 20 mm hasta 200 x 20 mm

Largos hasta 200 mm

Work pieces

  • With a bending force of 300 kN, the Professional Line is able to bend materials of up to 160×20 mm (copper). The hydraulic cylinders are located under the working face to allow for a maximum amount of work space. Special bending tools render even complex bends possible

CNC stop

  • The Professional Line features a CNC stop with a traverse path of approximately 1500 mm. Additional extensions are available on request. The bending software PowerBend accurately calculates the flat length as well as the stop position and transfers the results directly to the CNC control unit. High production accuracy is assured

Angular measurement

  • Our measuring accuracy is 0.1º. This is attained by using bending prisms with electronic angular measurement technology. The computer then calculates the required final stroke. The spring back of every bend is compensated regardless of material type. Our high angle accuracy of +/- 0.2º is achieved instantly with the first work piece. No adjustments are required. Material waste amounts will drop considerably. Even inconsistencies within a single piece of material are automatically adjusted

Stroke measurement

  • If the bending prisms with integrated angular measurement cannot be used due to their size, bending prisms without angular measurements can be used. Perhaps the distance between two bends is too short. In such cases the control unit can be switched from angular to stroke measurement. This method allows the selection of the bending ram distance. Setting accuracy is +/- 0.1 mm. A final stroke is usually not required

On-Going development

  • This line was developed by incorporating many customer requests plus our own 50 years of experience in the bending machine industry. This machine is our most ergonomic machine to date

Bending software PowerBend

  • Easy Handling
  • The Microsoft Windows® based software, PowerBend, is easy to learn. No CNC programming skills are required. All necessary inputs are prompted and displayed on the screen. Inputs can be corrected at any time and minimum distances are checked instantly to guard against improper inputs. The operator is allowed to use outside, inside, center line, and radius dimensions. Software can be switched between mm and inches
  • Calculated Values
  • The PowerBend software automatically calculates the flat length of each part being bent and determines the exact position of the side stop. Up to three bends can be calculated for one work piece
  • Program Storage
  • The program for each work piece can be stored as alphanumeric names up to 24 digits. The database allows storage of more than 200.000 different parts which can be located easily using the search and sort options
  • Languages
  • Software languages: German, English, Russian, French, Finnish
