Bending Machine Reflector Layout for Low-Distortion Beam Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bending machines face challenges in safely projecting bending information along a long press beam without distortion, with previous solutions risking damage from manipulation actions and suffering from significant image distortions, especially with larger machines.
Innovation Solution
A bending machine equipped with a projector positioned in the rear machine space above the insertion plane, using a reflector with a pivoted reflective surface to direct the light beam path upward and potentially along the machine's longitudinal expanse, allowing projection onto various horizontal surfaces including the metal sheet or floor, and utilizing a movable setup to minimize distortion and protect the projector from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the projector is disposed in the front working and manipulation space to project bending information directly onto the metal sheet, then the projection distance is reduced and image distortion is minimized, but the projector is exposed to damage from manipulation actions and metal sheet bending
Solution Approach 1:
A reflector is introduced as an intermediary component between the projector and the metal sheet. The reflector redirects the light beam from the projector (located in the safe rear machine space) onto the metal sheet in the front working space, enabling projection without direct exposure of the projector to harmful manipulation actions and metal sheet bending
Solution Approach 2:
The projection path is changed from a direct horizontal path to a redirected path using the reflector. The light beam travels from the projector in the rear space, reflects off the reflector positioned at an angle, and projects onto the metal sheet, effectively using spatial dimensionality to separate the projector location from the projection target
2Object-affected harmful factors
If the projector is disposed in the rear machine space to protect it from damage, then the projector is safe from manipulation actions and metal sheet bending, but projection distortion increases along the long press beam
Solution Approach 1:
The reflector serves as a mediator that enables the projector in the rear machine space to project images onto the metal sheet with minimal distortion. By positioning the reflector strategically and angling its reflective surface, the light beam path is optimized to reduce projection distortion while maintaining projector safety
Solution Approach 2:
The reflector is configured with a pivoted reflective surface that can be adjusted to optimize the light beam direction. This dynamic adjustment capability allows the system to compensate for projection distortion and maintain image accuracy despite the projector's protected rear position
3Adaptability or versatility
If the press beam is made longer to accommodate larger workpieces, then the machine capacity increases, but projection distortion becomes more significant for information display along the beam
Solution Approach 1:
The projection system uses the vertical dimension introduced by the reflector to redirect light beams along the longitudinal expanse of the press beam. This dimensional approach allows information to be projected at multiple locations along the beam without suffering from the distortion that would result from increasing the horizontal projection distance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively protects the projector from damage during operation, reduces distortion in the projection, and allows for clear, location-directed representation of bending information, enhancing operator safety and efficiency by using existing surfaces as projection areas.
Implementation Method 1
a reflector (18) with a first reflective surface (19) being disposed in the working and manipulation space (14), wherein the first reflective surface (19) is disposed so as to be pivoted by an angle relative to the horizontal, so that a light beam (17) impacting it from the light beam path (17) of the projector departs from the first reflective surface (19) as an outgoing light beam of a beam path (20) of the reflector in the direction of the insertion plane (12)

AI summary
A bending machine with a bending information display apparatus has a machine frame, a longitudinally extended, fixed machine table, and a longitudinally extended press beam. The longitudinal expanse and the press beam movement direction define a working plane. An insertion plane essentially normal to the working plane is defined by an upper machine table flat side or a lower tool disposed thereon. The working plane establishes a front working and manipulation space and a closed rear machine space. A projector disposed above the insertion plane in the rear machine space has a light beam path directed away from the insertion plane. A reflector disposed in the working and manipulation space has a first reflective surface pivotable by an angle to the horizontal so that a light beam incident from the projector beam path leaves the first reflective surface as a departing light beam toward the insertion plane.
