The working principle of hydraulic shearing machine

 Before operating the shearing machine, ensure you wear snug-fitting protective clothing with all cuffs securely fastened and jacket hems closed; avoid wearing, removing, or adjusting clothing near the machine to prevent entanglement. Always wear an ANSI-approved safety helmet with all hair fully contained, and refrain from operating the machine while wearing skirts, open-toed footwear (e.g., slippers), or dangling accessories like scarves.

 The operator must possess comprehensive knowledge of the equipment's structural design, operational parameters, and precise execution procedures, while strictly adhering to the prescribed performance specifications; any operation exceeding the designated performance limits is absolutely prohibited.

 Prior to initiating operation, verify the oil level in the oil cup and replenish grease in strict accordance with the equipment's lubrication guidelines.

 Prior to commencing work, the upper and lower blades must be properly aligned and secured. The blade gap should be meticulously calibrated based on the thickness of the steel plate to be sheared, typically maintaining a range of 5% to 7% of the plate's thickness. Following each adjustment of the gap, manually rotate the flywheel to ensure the upper and lower blades complete a full reciprocating cycle. Subsequently, verify the accuracy of the gap using a feeler gauge to confirm its suitability.

 Prior to operation, the back gauge must be accurately set and adjusted in strict accordance with the specifications of the cut workpiece. A mandatory pre-operational test run of 2-3 cycles without load should be conducted to verify adequate lubrication and confirm the absence of any operational abnormalities before commencing actual work.

 The use of percussion methods to adjust the back gauge or blade gap is strictly prohibited. Additionally, when adjusting the clearance between the guide rail and the blade edge, the machine must be brought to a complete stop before any adjustments

 During operation, it is strictly prohibited to reach into the cutting zone or manually handle materials. All material handling must be performed using appropriate tools or mechanical aids to ensure operator safety.

 To prevent foreign objects from entering the cutting zone and causing blade damage, ensure the workbench remains clear of all unrelated items during operation.

 When cutting sheets of varying thicknesses or materials, the plate spring pressure and blade gap must be appropriately adjusted to prevent spring failure or cutting edge damage. Cutting bars is strictly prohibited.

 During operation, maintain continuous vigilance for any abnormal malfunctioning of the clamping mechanism, clutch, or brake system. While cutting, ensure full concentration on the task. In the event of detecting any equipment abnormalities, immediately cease cutting operations, disconnect the power supply, and promptly notify designated maintenance personnel for intervention.

 The blade's cutting edge must be maintained in a sharp condition. Any signs of damage, wear, or dullness necessitate immediate sharpening or replacement to ensure optimal cutting performance and safety.

 Upon completion of work, the power supply must be disconnected, and routine equipment maintenance should be performed.
