5 formas de mantener su cizalla en plena forma
- Understand Your Machine
Ask the equipment operator about the operating condition of your shearing machine hydraulic system equipment. These include: whether the hydraulic system of the shearing machine is working normally; whether there are any abnormalities in the hydraulic pump; the time and results of the hydraulic oil testing cleanliness; the cleaning and replacement of the filter element; whether the hydraulic components were adjusted before the failure occurred; whether the sealing elements were replaced; what irregularities have occurred in the hydraulic system of the shearing machine before and after the failure; what failures have occurred in the system in the past and how they were eliminated, etc. It is necessary to know
2. Check that the machine is running well
2.1 Look at the actual condition of the shearing machine hydraulic system work, observe the system pressure, speed, oil, leakage, vibration, etc. whether there are problems.
2.2 Listen to the sound of the hydraulic system of the shearing machine, such as: impact sound; pump noise and abnormal sound; to determine whether the hydraulic system is working normally.
2.3 feel the temperature rise, vibration, crawling and the degree of tightness of the coupling to determine whether the shearing machine hydraulic system moving parts working condition is normal.
3.Follow a Basic Maintenance Plan
3.1 To operate in strict accordance with the operating instructions.
3.2 your shearing machine should be lubricated regularly, regularly and quantitatively according to the requirements of the lubrication chart before each start, and the oil should be clean and free from precipitation.
3.3 machine tools must often be kept clean, unpainted part of the anti-rust grease.
3.4 motor bearings within the lubricating oil should be regularly replaced and refilled, and often check whether the electrical parts work properly and safely.
3.5 regularly check whether the v-belt, handle, knob, button is damaged, serious wear and tear should be replaced in a timely manner, and report spare parts to replenish.
3.6Regularly check and repair switches, fuses and handles to ensure that they work reliably.
3.7 10 minutes before the end of each day, oil and lubricate the machine and scrub and clean the machine.
3.8 Non-designated personnel are strictly forbidden to operate the equipment, and the machine must normally stop when people leave it.
4.Make Repairs as Soon as Possible
If any damage, wear or improper adjustment is found, repair or adjust the shear immediately. Most catastrophic failures are caused by delays in simple maintenance. It’s almost always cheaper to fix a repair problem quickly than to correct the damage when the repair is ignored or delayed. In addition, the safety of the operator depends on timely maintenance.
By performing these simple tasks, the productivity of the shear can be maintained. When a cut remains appropriate, replacement costs and catastrophic failure can be avoided.
5.Set the Blade Properly
5.1 The key to prolong the service life of the blade and your shearing machine is to set the blade correctly. Setting the correct blade clearance will affect the transmission, slider, tool and cutting quality. In addition, before setting the blade, check whether the blade seat is flat, and ensure that the position of the tool is correct, so as to eliminate the blade cracking caused by displacement in the cutting process.
5.2 If the clearance is too tight, the metal between the blade and the machine tool will be stuck, resulting in incorrect cutting action. If the blade has no clearance, it will break. When the clearance is too loose, the blade acts like a hammer, exerting multiple forces on the parts of the machine, resulting in premature wear and failure.
5.3 The specific method of blade clearance adjustment of plate shears is to adjust the blade clearance of plate shears in a single stroke,. At that time, it is necessary to loosen the locking screw temporarily. When the blade of the upper shearer descends to the bottom dead center, turn the ball valve quickly to close the oil circuit, so that the upper tool rest of the shearer stops at the bottom dead center, and then lock the screw.Then, continue to open and close the ball valve slightly, so that the upper knife rest of the plate shearer rises gradually in the whole stroke. At this time, the blade edge clearance of the plate shearer can be measured step by step to check whether the blade edge clearance of the plate shearer is adjusted properly, Adjust and turn on the shearing machine for several cycles of shearing. Try to cut different thickness sheets from thin to thick. After ensuring that there is no abnormal situation, turn the handle to the required scale value.The ball valve is used to measure the gap uniformity between the upper and lower edges of the blade of the plate shearer.
Whether the blade gap of the plate shearer is appropriate or not is an important factor that affects the shearing quality and prolongs the blade life of the plate shearer
