Technical field
The present invention relates to a kind of device improving two-point press Synchronous Transmission precision, especially a kind of at two connecting rods
When lower dead point position, can make to keep consistent adjusting means away from working plate distance bottom two guide pillars of correspondence, further relate to
The control method of this adjusting means, belongs to metal forming machinery technical field.
Background technology
In two point or four point pressure machines, owing to adding man-hour it cannot be guaranteed that corresponding in two or four jointed gear unit
The centre-to-centre spacing of eccentric gear connecting rod guide pillar driving-chain completely the same, can cause being connected with two or four guide pillar lower end
Slide block because of left and right or front and back both sides asynchronous and tilt, affect forcing press precision, thus reduce stamping products qualification rate and shortening
Die life.In order to improve the synchronicity of two or four jointed gear unit, it is necessary to regulate each jointed gear unit driving-chain
The guide pillar lower end surface of the end distance away from working plate so that it is between deviation reduce as far as possible, could improve slide block run
Synchronicity.Prior art is: in the guide pin bushing left and right sides, respectively one piece of block with horizontal tapped through hole is fixed on crossbeam
On downside, push up guide pin bushing by being screwed into the screw of block, thus by changing guide pin bushing position on crossbeam is longitudinal, change
Connecting rod axis and the angle of jointed gear unit axis, thus improve the synchronicity that slide block runs.External screw thread and water because of screw
Having axial gap between the female thread of flat thread through hole, the contact surface between screw end face and guide pin bushing is less simultaneously, contact position
Face pressure between screw and guide pin bushing is very big, and being easily caused both of which has deformation；It addition, slide block is the most mobile and stamping forming
Vibrations so that screw not tight, cause guide pin bushing to move and make forcing press precision stability poor, need often to readjust, impact
The service efficiency of forcing press.
