Problems solved by technology
[0002] Existing large-scale forging machinery requires on-site operation by workers, and the safety of workers must be guaranteed. If only relying on some label warnings, it often does not get good results, and workers are not skilled enough to operate tiredly. And other factors, in case workers approach or touch large-scale forging machinery at the moment of operation, winemaking tragedies often occur

Embodiment Construction
[0015] Judging the alert area of large forging machinery based on theoretical data, such as figure 1 As shown, the three installation columns 1, 2, 3 are respectively erected on the same side of the forging machine, and the three installation columns 1, 2, 3 are arranged in a triangle to form a triangular warning area.
[0016] like figure 2 , 3 As shown, there are two rows installed on the mounting column 1, each row of three photoelectric sensor switches, one row is 4A, 5A, 6A, and the other row is 4B, 5B, 6B.
[0017] Two rows are installed on the mounting column 2, each row has three photoelectric sensor switches, one row is 7A, 8A, 9A, and the other row is 7B, 8B, 9B.
[0018] Two rows are installed on the mounting column 3, each row has three photoelectric sensor switches, one row is 10A, 11A, 12A, and the other row is 10B, 11B, 12B.
[0019] After installing the positions of the three mounting columns 1, 2, and 3, adjust the nine pairs of photoelectric sensor swit...

A photoelectric protection safety device for a large forging press relates to forging and pressing machinery, in particular to a safety protection production device of the large forging press. The safety device comprises three mounting columns respectively erected on the same side of the forging press, wherein the three mounting columns are oppositely arranged in a triangular shape, photoelectric sensor switches which are vertically arrayed are arranged on each mounting column, photoelectric sensor switches formed after the photoelectric sensor switches between every two adjacent mounting columns in the three mounting columns are matched are respectively connected to the control end of a relay, and the relay is connected to an alarming circuit. An interloper can be warned in advance by the safety device, equipment is shut down if warning is not effective, and small articles can be identified to avoid false warning.
Description
technical field [0001] The invention relates to forging machinery, especially its safety protection production device. Background technique [0002] Existing large-scale forging machinery requires on-site operation by workers, and the safety of workers must be guaranteed. If only relying on some label warnings, it often does not get good results, and workers are not skilled enough to operate tiredly. And other factors, in case workers approach or touch large-scale forging machinery at the moment of operation, tragedies often occur. Contents of the invention [0003] The purpose of the present invention is to propose a photoelectric protection safety device for large-scale forging machinery, which is equipped with an alarm area and its emergency termination of the operation area of large-scale forging machinery. object to prevent false positives. [0004] The present invention includes three installation columns erected on the same side of the forging machine re...
