How to tell if the shearer is working properly
A shearing machine is a machine that shears a sheet by reciprocating linear motion with one blade relative to the other. By means of the moving upper blade and the fixed lower blade, a reasonable blade gap is applied to apply shearing force to the metal sheets of various thicknesses, so that the plates are broken and separated according to the required size. Shearing machine is one of the forging machinery, the main role is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment.
Before you find out if the hydraulic shears are working properly, let's see how it works. The hydraulic shearing machine is a machine tool with simple structure and widely used in sheet metal processing. When working: the oil pump starts, the hydraulic oil first enters the pressure cylinder to press the sheet, and the other oil routing time relay controls the delay for about 2 seconds. Entering the upper chamber of the left cylinder, the oil in the lower chamber of the left cylinder is forced into the upper chamber of the right cylinder, and the oil in the lower chamber of the right cylinder is returned to the tank. Check the seals in good condition and replace the seals if damaged.
Touch the temperature rise, vibration, crawling and the tightness of the joint to diagnose whether the condition of the moving parts of the hydraulic system of the shearing machine is normal. So, how to determine whether the hydraulic shearing machine is normal and good? The actual condition of the hydraulic system work, observe whether the system pressure, speed, oil, leakage, vibration, etc. have problems, listen to the sound of the hydraulic system of the shearing machine, such as: impact sound; pump noise and abnormal sound; determine whether the hydraulic system works normal. Solution: Remove the piston, the key is fixed on the outer circumference of the piston and slide with the piston on the inner hole. Check the outer circumference of the piston to see if there is any polishing highlight. If it needs to be sanded, use it.
In practice, through years of experience in repair and transformation, many shearing machine products often fail to meet the needs of customers. Chinese shearing machine enterprises need to continuously penetrate the market to understand the different shearing machine customers of different shearing machine industries. Different needs. To determine whether the hydraulic shearing machine works normally, it should be observed from the following aspects: whether the hydraulic shearing machine hydraulic system works normally; whether the hydraulic pump has abnormal phenomena; the time and result of the hydraulic oil detecting cleanliness; the filter cleaning and exchange Whether the hydraulic components are adjusted before the fault occurs; whether the sealing components are exchanged; what abnormal phenomena have occurred in the hydraulic system of the shearing machine before and after the fault; what faults have occurred in the system to be repaired in a targeted manner.
