一般描述：Yantai Haige Machine Tools Co., Ltd. Was built in 1999, which specializes in producing steel finishing equipment, such as flaw detection, Series JY Bar Straightening Machine, Abrasive Belt Ginder, Drawing Machine, Shot Blasting Machine, Centerless Grinding Machine, CNC skiving and Roller Burnishing Machine and Auxiliary Machine etc. We also engage in continuous hard chrome plating equipment and heat treatment equipment.
Based on 15 years manufacture and design experience, our machines have been exported to Russia Vietnam, India, Pakistan, Iran, South Korea, North Korea, Taiwan and other countries and regions.
The whole set of PLC selects the S7 series product, realizing the communication with OP panel (touch screen), frequency changer and other sub-station. Select or enter the specifications of the steel bar to be tested on the OP touch screen of the console in the operating room. The PLC control system automatically adjusts the roller speed according to the thread pitch and test the running speed of the main machine.
Pneumatic parts can meet the mechanical action requirements. Electronic control part can meet the mechanical and pneumatic action requirements. The control is designed to be manual and automatic control. The actions are interlocked to ensure the safety and reliability of the operation. The switch of the controlling power with key and an emergency stop button with self-lock are arranged on the operation panel.
Eddy current testing technical index
(1) Mode of flaw detection: point probe type
(2) Detecting speed: matching the depth of ultrasonic flaw detection.
(3) Testing sensitivity : surface groove ( depth × width × length ) 0.2X0.1X25mm
(4) equipment comprehensive performance index:
SNR: ≥ 8 dB;
Leakage rate : 0 ;
False alarm rate: ≤ 1%;
Stability sensitivity fluctuation is less than 2dB
End blind area ≤ 50mm
(5) The processing of the detection defect: the sound / light alarming signal is given immediately; and the marking system is used to mark the standard, the circumferential marking precision is better than 50mm, and the separation of the original and the waste is realized.
(6) Flaw detection statistics: immediately on the screen of the flaw detection instrument to display the quantity of genuine and waste products.
(7) Record and store: according to card number, branch number (including furnace number, steel grade, etc.) record, store and output print test parameters, test results and detection curve (can store one year's inspection data.
(8) Print detection report: compile and print detection report.
