[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.
[0020] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0021] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The bending machine safety protection device adjustment mechanism shown includes a light curtain fixed sheet metal 1, a light curtain rotating seat 2 is provided on the light curtain fixed sheet metal 1, and a light curtain clamping pin 3, a light curtain adjustment block 4, a light curtain transmission pin 5 and a fine-tuning adjustment bolt 6 are symmetrically provided on both sides of the light curtain rotating seat 2. The outer side of the light curtain rotating seat 2 is fixedly installed with a light curtain adjustment upper sheet metal 7 through the bolts on the light curtain clamping pin 3, and the upper end of the light curtain adjustment upper sheet metal 7 is installed with a light curtain adjustment upper sheet metal 8 through a fixing bolt. The upper surface of the light curtain fixed sheet metal 1 has an upwardly protruding boss 9, and the lower end of the light curtain rotating seat 2 is provided with an internal adjustment groove 10 that cooperates with the boss 9.
