We specialize in engineering upgrades for older machinery to achieve the following:
Current performance data
Limitations of the current operation, production figures, etc.
Any available drawings and literature on the machinery
Relevant field measurements: dimensions, speeds, cycles, etc.
Prepare CAD drawings of the existing mechanism
Analyze the motion analytically, graphically and by modeling
Analyze the functional parts for their action, wear, life, etc.
Define parameters for redesign
Generate new motion and cycle diagrams.
Replace mechanical actuators with electrical (servos) where appropriate.
Generate new cams and N-C code for milling.
Improve the design, material of functional parts.
Prepare CAD drawings and Bill of Materials.
Provide fabrication support as required.
Support installation, start-up and tuning.
WEBCON specializes in a proprietary computerized method (CAMdes) for designing cams. The shape of the acceleration diagram is postulated in terms of trigonometric functions, and integrated twice with respect to time in order to determine positions. Cams could be internal, external or trapped.
The cam profile is checked for radius of curvature, transmission angles and toggling. High speed cams are provided with cutouts for dynamically balancing. Any size cams can be designed by this system.
The CAMdes outputs a CAD drawing of the cam, as well as G-Code for N-C milling operation.
Click to see the standard geometries handled by CAMdes. Special purpose geometries are written for non-standard situations.
Mechanisms DesignWEBCON has a computer program library of frequently used mechanisms
The output of these programs are the displacement, velocity and acceleration diagrams. Also outputted are the transmission angles to check for mechanical efficiency and toggling.
Mechanical to Electrical
Where applicable, the mechanical actuators and linkages are substituted with electrical systems, such as servo drives, electrical actuators, solenoids, etc.
General Mechanical ElementsThe improvement in mechanical elements is geared towards reducing maintenance and improving accuracy and reliability of motion. The thrust is towards the following replacements:
