Abstract
An apparatus which forms a controlled engageable low maintenance seal between the slide and the gib of a mechanical press and which prevents lubricant from exiting the area between the slide and the gib and entering the die space. The sealing arrangement is selectively actuatable depending upon an operational condition of the press.
Claims27
A press, comprising:
- a frame;
- a slide mounted within the frame for reciprocation relative thereto;
- a gib connected to the frame;
- and
- a plurality of inflatable linear seals, said plurality of inflatable linear seals located between said gib and said slide, said plurality of inflatable linear seals selectively inflatably interacting with said gib and said slide to thereby form a cavity bounded by said gib, said slide, and said plurality of inflatable linear seals.

A press, comprising:
- a frame;
- a slide mounted within the frame for reciprocation relative thereto;
- a gib connected to the frame;
- a plurality of inflatable linear seals, said plurality of inflatable linear seals located between said gib and said slide, said plurality of inflatable linear seals selectively inflatably interacting with said gib and said slide to thereby form a cavity bounded by said gib, said slide, and said plurality of inflatable linear seals;
- an inflator for selectively inflating said linear seals to thereby selectively form said cavity bounded by said gib, said slide, and said plurality of inflatable linear seals;
- and
- a controller for receiving a plurality of values corresponding to press operational condition and for actuating said inflator when one of said plurality of values exceeds a predetermined measure.
4 more elements
A press, comprising:
- a frame;
- a slide located within the frame for reciprocation relative thereto;
- a gib connected to the frame;
- and
- an inflatable linear seal, said inflatable linear seal mounted proximate said slide and configured for selectively inflatably forming a seal between said slide and said gib.
2 more elements
A press, comprising:
- a bed;
- a pair of uprights connected to said bed;
- a crown connected to said uprights;
- a slide located within said uprights for reciprocation relative thereto;
- a gib attached to the press;
- and
- a selectively inflatable seal connected to the press, said selectively inflatable seal being configured for selectively inflatably forming a seal between said slide and said gib.

A press, comprising:
- a bed;
- a pair of uprights connected to said bed;
- a crown connected to said uprights;
- a slide located within said uprights for reciprocation relative thereto;
- a gib attached to the press;
- a selectively inflatable seal connected to the press;
- an inflator for selectively inflating said seal;
- and
- a controller for receiving a plurality of values corresponding to press operational condition and for actuating said inflator when one of said plurality of values exceeds a predetermined measure.
6 more elements
A press, comprising:
- a frame;
- a slide mounted within said frame for reciprocation relative thereto, said slide having four corners, each of said corners having a front-to-rear touch surface and a right-to-left touch surface;
- a plurality of wear plates having wear plate contact surfaces, one of said plurality of wear plates affixed to each of said touch surfaces of said slide;
- a plurality of seal contact blocks, one of said plurality of seal contact blocks extending outwardly from each of said wear plates;
- a gib affixed to said frame, said gib having a plurality of gib contact surfaces opposite and substantially parallel to said wear plate contact surfaces;
- a plurality of inflatable linear seals connected to said gib, one of said plurality of linear seals selectively contacting each of said seal contact blocks and forming four vertically sealed cavities, each of said vertically sealed cavities vertically enclosing said front-to-rear touch surface and said right-to-left touch surface at each corner of said slide;
- a plurality of linear strips of wear material, one of said plurality of linear strips of wear material affixed to each of said plurality of linear seals, said plurality of linear strips selectively contacting said slide;
- and
- a collection tray for collecting lubricant from each of said plurality of sealed cavities.
