Back Gauge Elevation in Press Brakes With One Ball Screw
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The second type back gauge device in press brakes requires adjustment for synchronizing two ball screw mechanisms for elevation, which is time-consuming and labor-intensive.
Innovation Solution
The press brake is configured with only one ball screw mechanism for elevation, which includes a ball screw and a nut member, allowing the pair of elevating members to be ascended and descended by the driving of one motor, simplifying the adjustment work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two ball screw mechanisms are used for elevation in the back gauge device, then the elevating operation can be performed, but the adjustment work requires a lot of time and effort due to synchronization requirements
Solution Approach 1:
The patent merges the two separate ball screw mechanisms into a single ball screw mechanism. The stretch connects the first and second elevating members, and the single ball screw mechanism drives both elevating members simultaneously, eliminating the need for synchronization adjustment between two independent mechanisms while maintaining reliable elevating operation.
2Reliability
If two ball screw mechanisms are used for elevation in the back gauge device, then the elevating operation can be performed, but the device complexity increases
Solution Approach 1:
The patent reduces device complexity by combining two separate ball screw mechanisms into one. The single ball screw mechanism is connected to both the first and second elevating members through the stretch, simplifying the overall structure while maintaining the necessary elevating function for the back gauge device.

AI summary
A press brake includes elevating members each provided to respective one of a pair of support blocks so as to be able to ascend and descend, and extending vertically. A ball screw is provided to a first elevating member so as to be rotatable, and a nut member to be screwed into the ball screw is provided to a first support block. One end side of a stretch in the lateral direction is connected to an upper end portion of the first elevating member, and the other end side of the stretch in the lateral direction is connected, so as to be rotationally movable, to an upper end portion of a second elevating member. A support mechanism for supporting the stretch from below is provided to the first elevating member, and an abutting member is provided to the stretch.
