Abstract
A drawing apparatus is assembled from modular units utilizing modular path-forming members and holder modules which can carry the drawing die and drawing carriages shiftable on the guide modules. The drives for the carriages are individual linear motors whose stationary components are the modular path-forming members disposed end-to-end.
Claims10
A modular drawing apparatus for drawing an elongated workpiece, said apparatus comprising:
- at least one elongated path-forming module alignable contiguously and directly with others of said path-forming modules to define an uninterrupted elongated travel path;
- at least one holder module engaged with said at least one elongated path-forming module and constructed and arranged for selective attachment to said others of said path-forming modules;
- a drawing die mounted in said at least one holder module;
- and
- a drawing carriage provided with a device engageable with said workpiece and a part carrying said device and displaceable along said path relative to said at least one elongated path-forming module, said part and said path-forming module forming mutually interactive elements of a linear motor for direct displacement of said carriage along said path, said linear motor encompassing at least one linear motor unit having a stationary part forming one of said reactive units and integrated in said path-forming module, said linear motor having a primary part and a secondary part, and said path-forming module encompassing one of said parts and the other of said parts being connected with said drawing carriage, the secondary part being formed as a middle rail or two parallel outer rails of the path-forming module, said path-forming module being directly connected in-line to another path-forming module, corresponding rails of said path-forming modules being connected contiguously with one another.
A modular drawing apparatus for drawing an elongated workpiece, said apparatus comprising:
- at least one elongated path-forming module alignable contiguously and directly with others of said path-forming modules to define an uninterrupted elongated travel path;
- at least one holder module engaged with said at least one elongated path-forming module and constructed and arranged for selective attachment to said others of said path-forming modules;
- a drawing die mounted in said at least one holder module;
- and
- a drawing carriage provided with a device engageable with said workpiece and a part carrying said device and displaceable along said path relative to said at least one elongated path-forming module, said part and said path-forming module forming mutually interactive elements of a linear motor for direct displacement of said carriage along said path, a plurality of said path-forming modules being connected contiguously together to form said path, a plurality of said carriages being provided along said path, said carriages being displaceable on a guide assembled in a modular construction from a plurality of guide modules.
A drawing line for drawing an elongated workpiece, comprising at least two modular drawing units, each of said drawing units comprising at least one drawing slide engageable with said workpiece, at least one elongated path-forming module alignable contiguously and directly with others of said path-forming modules to define an uninterrupted travel path, at least one holder module engaged with said at least one path-forming module of the respective unit and constructed and arranged for selective attachment to others of said path-forming modules, a respective drawing die mounted in each holder module whereby said workpiece traverses said dies, and a respective drawing carriage provided with a device engageable with said workpiece and a part carrying said device, said carriages being displaceable in the respective path-forming modules, said part and path-forming module of each unit forming mutually interactive elements of respective linear motors for direct displacement of said carriages along said path, the path-forming modules of each unit being directly in line with and connected to the path-forming modules of the other unit, and a computer for controlling the linear motors and movement of the respective carriages for coordinated drawing of the workpiece through the dies without buffering of the workpiece between said units.
