What Is a Shearing Machine?
Shearing machine (English name: plate shears; guillotine shear) is a machine that uses one blade to perform reciprocating linear motion to cut the plate relative to the other blade. By moving the upper blade and the fixed lower blade, a reasonable blade gap is used to apply shearing force to metal plates of various thicknesses to break and separate the plates according to the required size. Shearing machine is one of the forging machinery, its main function is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, electric power, electrical appliances, decoration and other industries to provide special machinery and complete sets of equipment.
Shearing machine maintenance
- 1. Operate strictly in accordance with operating procedures;
- 2. Lubricate the oil regularly, fixedly and quantitatively as required by the lubrication chart before each start-up. The oil should be clean and free of precipitation.
- 3. The machine must always be kept clean, and the unpainted parts are rust-proof grease;
- 4. The lubricating oil in the motor bearings should be changed and refilled regularly, and the electrical parts should be checked regularly for safety and reliability.
- 5. Regularly check whether the V-belt, handles, knobs and buttons are damaged. If they are severely worn, they should be replaced in time and reported for replacement.
- 6. Regularly inspect and repair switches, insurances, and handles to ensure that they work reliably;
- 7. Lubricate the machine tool and clean the machine tool 10 minutes before work every day;
- 8. It is strictly forbidden for non-designated personnel to operate this equipment. Usually, people must stop the machine.
Shearing machine technical requirements
- Shearing machine is a kind of cutting equipment which is widely used in machining. It can cut steel plate materials of various thicknesses. The commonly used shears are divided into three types: flat shear, roll shear and vibration shear. Flat shears are used in large quantities. Most of the shears with a shear thickness of less than 10mm are mechanical transmissions, and those with shear thicknesses greater than 10mm are hydraulic transmissions. Single or continuous cutting of metal is usually performed with a foot or a button. When operating the shears:
- 1. Before work, carefully check whether the parts of the shearing machine are normal, whether the electrical equipment is intact, and whether the lubrication system is unblocked; remove debris, such as tools, measuring tools, and corner waste, from the table and its surroundings.
- 2. Don't operate the shearing machine by one person alone. Two to three people should coordinate the feeding, control the dimensional accuracy and the reclaiming, etc., and make sure that one person takes the unified command.
- 3. Adjust the clearance of the shears of the shears according to the specified thickness of the shears. It is not allowed to cut 2 different specifications and different materials at the same time; The cut sheet requires a flat surface, and it is not allowed to cut a narrow sheet that cannot be compacted.
- 4. Shearing belts, flywheels, gears and shafts must be equipped with protective covers.
- 5. The fingers of the shearing machine operator should keep a distance of at least 200mm from the mouth of the scissors and leave the pressing device. The protective fence placed on the trigger should not block the operator's eyes and not see the cut. The waste generated after the operation has edges and corners, and the operator should remove it in time to prevent stab wounds and cuts.
- 6. Flywheels, gears, shafts, tapes and other moving parts of the shears should be provided with protective covers.
- 7. Place a fence to prevent the operator's hand from entering the area where the scissors fall. It is strictly forbidden to pick up ground waste during work to avoid being injured by falling workpieces.
- 8. It is not possible to cut hardened materials, and never allow cutting to exceed the working capacity of the shearing machine.
Shearing machine troubleshooting
- 1. Ask the equipment operator about the operating status of the hydraulic system of the shears. These include: whether the hydraulic system of the shearing machine is working normally; whether the hydraulic pump is abnormal; the time and results of the hydraulic oil detection cleanliness; the cleaning and replacement of the filter element; whether the hydraulic components have been adjusted before the failure; whether the seal has been replaced Components; what abnormalities have occurred in the hydraulic system of the shears before and after the failure; what faults have occurred in the system in the past, how to eliminate them, etc., need to be understood one by one.
- 2. Look at the actual working condition of the hydraulic system of the shearing machine, and observe whether there are any problems with the system pressure, speed, oil, leakage, vibration, etc.
- 3. Listen to the sound of the hydraulic system of the shears, such as: impact sound; pump noise and abnormal sound; determine whether the hydraulic system works normally.
- 4. Touch the temperature rise, vibration, crawling and the tightness of the joint to determine whether the working condition of the moving parts of the hydraulic system of the shears is normal.
Shearing machine purchase correctly
- During the purchase, you should pay attention to the following points:
- 1. According to your own demand parameters, determine the specifications of the purchased machine. At the same time, take into account that after the expansion of the size of the enterprise, there is a certain margin to determine the parameters of the machine. In particular, the shearing machine has a range of requirements for the material thickness of the cutting material, the size of the slitting machine, and the like. After the model parameters of the machine are determined, the manufacturer can be contacted to purchase.
- 2. Confirm the manufacturers of the machines to be purchased. In this link, it is often the easiest to ignore, because no matter which manufacturer is contacted, the manufacturer will basically inform the professional production of the model. In fact, the models produced by different manufacturers Often different, manufacturers often provide various models of products through the way of adjusting goods. So users should pay special attention to choosing the one that suits them best.
- 3. After contacting a number of enterprises that produce machines, after obtaining the price, parameters, payment and payment methods of the machine, the most important step is to choose the manufacturer to buy. Generally, after selecting the highest and lowest prices, choose a trusted manufacturer, which can get better price-performance ratio, while ensuring quality and after-sales service.
- 4. Select a few special manufacturers for comparison, and learn more about the use of machine tools, machine quality, and especially after-sales service. Comprehensive consideration of various aspects, choose the best price, best service manufacturers.
- 5. After confirming the manufacturer, the next step is to sign the contract to pay the deposit, take delivery with cash or cash on delivery and other related matters. [2]
