Air hammers, as core equipment in industrial scenarios such as forging and powder blockage cleaning, are widely used in multiple fields including mechanical manufacturing, mining, chemical engineering, and building materials. It includes both free forging air hammers used for metal forging and pneumatic striking hammers for preventing clogging in silos. Different types of air hammers share both common safety guidelines and their own specific norms in terms of operation logic. This article will systematically sort out the standardized operation methods of air hammers by integrating equipment structure, operation procedures, risk prevention and control, etc., to help operators achieve safe and efficient operations.
Ⅰ. Before Operation: Build the first line of defense for safety
The core prerequisite for operating any air hammer is to do a good job in the preparatory work in advance and avoid more than 80% of common safety hazards from the source.
1. Personnel qualification confirmation
Operators must undergo professional and systematic training to fully master the structural principle, performance parameters, risk points and emergency response methods of the air hammer they operate. Only after passing the assessment can they independently take up their posts. Untrained personnel are strictly prohibited from operating the equipment without authorization. Apprentices must operate under the full guidance of certified teachers or experienced masters. Other irrelevant personnel should maintain a safe observation distance of more than 1.5 meters and are strictly forbidden to approach the equipment operation area. Before starting work, it is necessary to wear a full set of personal protective equipment as per the regulations: safety helmet, shock-resistant safety shoes, anti-slip gloves, and protective glasses. In an working environment with noise exceeding 85 decibels, additional soundproof earplugs should also be worn to prevent occupational health injuries.
2. Comprehensive inspection of the equipment
Before operation, a comprehensive inspection of the equipment must be carried out, and no detail should be overlooked.
(1) Structural component inspection: Check whether the main structure such as the machine body, hammer head, anvil seat, etc. have any cracks, deformations, corrosion or other damages. Pay special attention to confirming that the fastening pins, wedges and cross pins of the upper anvil and hammer rod are not loose or missing. The hammer anvil adopts a dual fixation structure of threads and limit sliders to ensure that it will not loosen or pop out during operation.
(2) Power system inspection: For forging type air hammers, confirm that there is no abnormal wear on the reducer, crankshaft and connecting rod of the transmission mechanism. For pneumatic striking hammers, check that the air source pressure is stable within the standard range of 0.3 to 0.7MPa, that the air pipe is undamaged or leaking, and that the solenoid valve operates sensitively and reliably.
(3) Safety device inspection: Confirm that the emergency stop buttons, guardrails, protective nets and other safety facilities of the equipment are in good condition and effective. The warning signs on the surface of the equipment such as "Do Not Approach" and "Protective Equipment must be worn" are clear and complete, without any obstruction or detachment.
(4) No-load test run: Start the equipment and run it idle for 3 to 5 minutes to ensure smooth movement of the hammer head without any jamming or abnormal noise. It is strictly prohibited to operate the hammer anvil in an empty state to avoid severe impact damage to the hammer head and anvil seat.
3. Inspection of the working environment
Clear away debris and waste materials in the operation area, keep the ground clean and free of oil stains and standing water, and prevent operators from slipping and getting injured. Confirm that the work site is well-ventilated. It is strictly prohibited to operate air hammers in flammable and explosive hazardous environments. Appropriate fire-fighting equipment should be provided around the site, and unobstructed emergency escape routes should be reserved. The operation area for forging air hammers should have the storage area for high-temperature workpieces cleared in advance to prevent unauthorized personnel from entering and getting scalded by high temperatures.
Ⅱ. During operation: Strictly adhere to norms to avoid operational risks
During the formal operation process, it is essential to strictly follow the standardized operation procedures and eliminate all non-compliant operation behaviors.
1.Key points for operating forging air hammers
Before starting the equipment, it is necessary to confirm that the hammerhead is in a safe parking position. It is strictly prohibited to start the equipment when the hammerhead has not returned to its original position.
When performing forging operations, both hands must maintain a sufficient safe distance from the hammer head and the die. It is strictly forbidden to insert hands between the hammer head and the anvil seat to adjust the workpiece. Select the appropriate striking force based on the material of the workpiece. It is strictly prohibited to forge overburned or already cooled metal billets to prevent the workpiece from shattering and flying, causing injury.
During the operation, one must concentrate fully. When multiple people cooperate in the operation, clear and unified command signals must be given to avoid misoperation. Keep a close eye on the operating status of the equipment at all times. If any abnormal noise, air leakage, or abnormal pressure is detected, immediately stop the machine, cut off the power source, and conduct an inspection.
Overloading forging is strictly prohibited. Do not use small-tonnage air hammers to process large-sized workpieces that exceed their parameter range to prevent equipment components from breaking and flying out due to overload.
2. Key points for operating pneumatic striking Hammers
When installing, the hammer body must be vertically fixed at the designated position in the silo. The installation height should not be less than 1/3 of the height of the silo cone. Multiple air hammers should be installed in a cross manner rather than symmetrically to ensure the effective transmission of vibration force and avoid excessive local impact force from damaging the silo wall.
When using it for the first time, start adjusting from a low pressure and gradually increase the pressure to adjust the striking force. Avoid using the highest pressure at the very beginning to impact, which may cause deformation of the material bin or breakage of the magnetic piston inside the hammer body. Set the knocking interval reasonably in coordination with the time relay to avoid continuous high-frequency knocking causing spring fatigue and fracture.
During the operation, it is strictly prohibited for personnel to bring their body parts close to the impact area of the air hammer. Regularly check the fastening bolts of the installation base to prevent the bolts from loosening due to long-term vibration and the air hammer from falling off and causing a fall accident.
Ⅲ. After operation: Wrap up properly to ensure long-term safety
Proper finishing after the completion of work is a crucial step in extending the service life of equipment and avoiding secondary hazards. First, reset the operation handle of the equipment to ensure that the hammer head is smoothly parked at a safe position. Then, cut off the air source and power supply in sequence, and clean the dust, oil stains and residual materials from the operation on the surface of the equipment. Add lubricating oil to the moving parts of the equipment according to the lubrication cycle, check the wear condition of vulnerable parts such as sealing rings and wear-resistant rings, and replace the aged and failed parts in time. Fill in the equipment operation records and inspection ledgers completely, register and report in detail the abnormal situations found during this operation, arrange professional personnel to rectify the hidden dangers, and strictly prohibit the equipment from being put into the next operation while "faulty". Finally, tidy up the work site, put the workpieces and tools back in place, turn off the main power and gas switches in the work area, and only leave after confirming there are no open flame hazards.
Ⅳ. Emergency Response and Daily Maintenance: Building a full-cycle safety system
Formulate a complete and specialized emergency response plan. For common accidents such as mechanical injuries, high-pressure gas leakage, and high-temperature scalds, clearly define the emergency response procedures and rescue contact information. Regularly conduct emergency drills to ensure that operators can correctly handle emergencies in the first instance and minimize the harm. Establish a regular maintenance and upkeep system. Conduct a tightening check on the fasteners once a week, carry out a comprehensive inspection of the seals of the pneumatic system and the circuits of the electrical control system every month, and conduct a safety performance calibration of the entire machine once every quarter. Through systematic full-cycle management, not only can the service life of air hammers be effectively prolonged and production efficiency be enhanced, but also all kinds of safety accidents can be fundamentally prevented, ensuring the personal safety of operators and the stable production of the enterprise.
