COLDFORM® 2D & 3D METAL COLD FORMING SIMULATION SOFTWARE

A very broad application scope COLDFORM® meets the needs of industrialists in many fields: • design and manufacture of parts formed from sheets ranging in thickness from moderate to high (clockmaking, precision mechanics, etc.); • design and manufacture of assemblies: screws, nuts, bolts, washers, etc.; • design and manufacture of motor parts: shafts, gears, rings produced by ring rolling, cold-formed parts. Significant cost and productivity gains The benefits of COLDFORM® can be observed at all steps in your activity During the R&D phase, for the development of innovative or complex...

Rapid computation for precise results COLDFORM® allows you to optimize your forming operations and to precisely predict: • the exact geometry and dimensions of the definitive parts, taking spring-back into consideration; • material yield throughout the forming sequence; • possible underfill and fold; • fibering and stress distribution; • marking and monitoring of specific surfaces, such as cutting surfaces, from the initial billet to the final shape; • damage and rupture criteria; • residual stress distribution; • etc. but also material displacement, plastic deformation, temperature and all...

Bevel gear forging simulation: contact analysis at various steps in the process (contact surfaces are shown in blue). Cold forming of an automotive part on a three-pass machine, taking press stiffness into account. (K-Won, Korea) / 5 / Some examples of cold forming processes simulated by COLDFORM®: • Closed die forming • Stamping • Cutting, shearing and piercing • Orbital forging • Hydro forming • Extrusion process • Riveting and crimping process • Incremental forging • Thread rolling • Ring rolling Stress distribution in a 7-component assembly. Stress analysis is performed on all 7...

Validate your equipment choices, extend die service life and reduce die costs COLDFORM® allows you to validate your equipment choices by precisely determining the press required to form your parts. Its database contains models for: Prediction of press force required to forge a screw using a mechanical press • mechanical presses, • hydraulic presses, knuckle presses, • orbital forging presses, • circular rolling mills. COLDFORM® allows you to analyze die strength in order to extend their service life. The software can compute stress distribution within the die, along with deformations, wear,...

COLDFORM® application example The following part is produced in four steps, with annealing operations. COLDFORM® simulates and chains each step in the process in order to study the complete forging sequence. The simulation precisely computes part changes during the forming steps. The following illustration shows a comparison between the actual part and the simulation result. In addition to predicting the overall shape, COLDFORM® also reveals any local defects. Elliptical contact area S-shaped line An initial examination of the results enables contact and non-contact zones to be easily...
