Description

Technical Field

[0001] The utility model belongs to the technical field of bolt processing, and in particular relates to an error-proofing system for a servo press. Background Art

[0002] High-lock bolts are widely used in the aviation industry. Their processing requires stamping the bottom plate screw structure, which is then formed using a servo press through cold processing. However, due to human factors, continuous processing is not possible during the servo press process. Processing is interrupted during the process, but the product remains in the equipment. Due to the small size of the product, the operator cannot accurately determine whether the product has been processed or not. This can lead to duplicate processing or missed processing when the operator continues to process the product. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above shortcomings and provide a servo press error-proofing system that records product processing status, counts and analyzes data through an electronic system, and avoids repeated processing and missed processing.

[0004] The purpose of the utility model and the solution of its main technical problems are achieved by adopting the following technical solutions:

[0005] The utility model discloses a servo press error prevention system, comprising a sealing box A, a ring counter, a sealing box B, a time delay relay A, a program memory, an interrupt instruction, a reset switch, a device, a power start switch, a device counter, a time delay relay B, and an air blowing device, characterized in that: the device is respectively connected to the interrupt instruction, the reset switch, and the power start switch through wires, the reset switch is connected to the power start switch through wires, the power start switch is connected to the device counter through wires, the device counter and the interrupt instruction are connected to the program memory through wires, the program memory is respectively connected to the time delay relay A and the delay relay B through wires, the delay relay A is connected to the ring counter through wires, the ring counter is respectively connected to the sealing box A and the sealing box B, the sealing box A is connected to the air blowing device through a pipe, and the air blowing device is connected to the time delay relay B through a wire.

[0006] The sealed box A consists of a box body A, a baffle A, a panel A, and an inclined plate A. The inclined plate A is installed at the lower end of the box body A, the panel A is inserted into the card slot provided on the upper portion, the baffle A is inserted into the card slot provided in the front portion, the discharge port A is installed on the baffle A, the feed port A is provided on the panel A, and the discharge port A is connected to the ring counter.

[0007] The sealing box B consists of a box body B, a baffle B, a panel B, a feed port B, and an inclined plate B. The inclined plate B is installed at the lower end of the box body B, the panel B is inserted into the card slot set on it, and the baffle B is inserted into the card slot set in the front. The feed port B is installed on the panel B, and the feed port B is connected to the ring counter.

[0008] The device is a servo press.

[0009] Compared with the prior art, the utility model has obvious beneficial effects; it can be seen from the above technical scheme that: by connecting the interrupt instruction, the reset switch, and the power start switch to the device through wires, the reset switch is connected to the power start switch through a wire, the power start switch is connected to the device counter through a wire, the device counter and the interrupt instruction are connected to the program memory through a wire, the program memory is connected to the delay relay A and the delay relay B through a wire, the delay relay A is connected to the ring counter through a wire, the ring counter is connected to the sealing box A and the sealing box B, the sealing box A is connected to the blowing device through a pipe, and the blowing device is connected to the delay relay B through a wire.

[0010] 1) When the power start switch button of the device is pressed to process a part, the device counter output is displayed as 1. When the processed part is taken out of the sealed box and enters the sealed box through the hose with the inductive ring counter, the inductive ring counter displays 1. The program memory receives the information that the device counter value = the ring counter value, the product processing status is normal, and the product can continue to be processed.

[0011] 2) When the power on button is pressed to process a part, the device counter output shows 1. The processed part is not removed and placed in the sealed box. The ring counter does not receive any information and displays 0. After the program memory receives information that the device counter value is ≠ the ring counter value, it sends an interrupt command. After receiving the command, the device cannot start, indicating the risk of repeated processing. Processing can only be continued after the abnormality is eliminated and reset.

[0012] 3) When the power on / off button is not activated, the device counter output displays 0. When a worker removes a part and places it in a sealed box, the ring counter receives information indicating 1. After the program memory receives information indicating that the device counter value is ≠ the ring counter value, it sends an interrupt command. Upon receiving the command, the device fails to start, indicating a risk of missed parts or mixed parts. Processing can only resume after the anomaly is corrected and reset. When processing parts using this system, if the equipment stops, it must be due to an anomaly in the part processing. Ultimately, the PLC receives information based on the device counter and the ring counter values to determine the part processing status, preventing missed or duplicated parts. This system records product processing status and uses electronic systems to collect and analyze data, preventing duplicate or missed parts. BRIEF DESCRIPTION OF THE DRAWINGS
