First, rubber injection molding machine the rubber mold wear curve for regular maintenance exists in every mold. Rubber mold repair is an abnormal wear and tear in the field, and the amount of stamping processing during this time is easy to learn. When the processing quantity is satisfied, the realization of rubber mold maintenance and maintenance plan are not only easy to learn maintenance items, but also easy to control the maintenance time.
2. Improved maintenance In order to extend the life of the mold, stable quality, easy maintenance, etc., some molds are improved for special maintenance.
Third, the daily maintenance refers to normal rubber mold cleaning, inspection, and moved to oil. This work is usually to confirm that the mold is in a normal state, and abnormalities can be detected early.
Fourth, there will be some changes in the processing of rubber molds for maintenance in an accident state, and the country cannot continue to use them. For example, the burr becomes larger, the wrong size, such as scars, burning of mold parts. The contents of mold repair and maintenance started due to similar abnormalities are called accidents. This kind of maintenance is usually used up to near limit, if the time of rubber mold maintenance cost is more important, life is short of mold. Because this is a sudden maintenance, there must be a planned shutdown of the equipment, and emergency repairs.
There are many obvious abnormalities in Swiss type CNC lathes. In some economical CNC systems, there is no alarm. Even if an alarm occurs sometimes, the alarm message indicates that it is not an alarm that you see abnormal. Creeping and vibration of machine tools are obvious examples. When the CNC lathe is running at a low speed, the machine tool table moves forwards peristally; when the machine tool is running at a high speed, vibration occurs.
The vibration classification of Swiss type CNC lathes generally has two main categories, forced vibration and self-excited vibration. On CNC lathes, milling machines and grinders, forced vibration of the rotary spindle system is often seen, and its frequency depends on the speed of the rotary spindle system. There are many types of self-excited vibration that occur on machine tools, and the system's torsional or bending self-excited vibration;
Bending or torsional self-excited vibration of the machine bed, column, beam and other supporting parts; there are also relaxation friction self-excited vibration (commonly known as creeping) that occurs when moving parts such as worktables are running at low speed. This type of self-excited vibration that is manifested as a strong relative vibration between the tool and the workpiece during metal cutting is commonly referred to as flutter.
Everyone sees the anti-theft soft label in the supermarket goods. The soft label is simple to use, has good anti-theft effect and low cost, and can be directly attached to the product. Anti-theft soft tags include acoustic magnetic soft tags and radio frequency soft tags. There are various shapes, uhf mini hard rfid tag, so do you know its characteristics?
The uhf mini hard rfid tag can be considered as the electronic version of the barcode. Its working principle is the radio principle. The numbering information in the RFID tag chip is obtained through the carrier wave and modulation of electromagnetic waves. The operating frequency of the RFID tag is 8.2 MHz. 0.8-1.2 meters, cheap and reliable, suitable for various goods.
uhf mini hard rfid tag has the following characteristics: RF soft tags cannot be directly attached to metal or foil products. RFID radio frequency soft tags cannot overlap (more than two). Labels should be applied as flat as possible. The bonding surface should be as small as possible and not folded. It cannot be less than 120 degrees.
RFID tags are generally more rugged and are not affected by the environment. They can withstand harsh environments such as high temperature and water, and acid and alkali. RF soft tags have a large amount of data storage. Compared with traditional tags, they have a larger capacity (1-1024bit), and the data can be updated at any time. Unlike a barcode, an RFID tag cannot be copied. It is a special number. The contents of the label can be read and written repeatedly.
Sometimes the engine can work normally at idle and medium speeds, but at the moment of sudden acceleration, the carburettor fires and fires.
Honda GX120 carburetor The cause of this failure is mainly due to the lean mixture. The mixture is too lean, making the combustible mixture burn slowly, so that the combustion process continues until the intake air starts, the intake valve opens, and the mixture in the cylinder is still burning. Due to the high pressure in the cylinder, it is burning. The combustible gas mixture rushed into the carburetor, ignited the combustible gas mixture in the carburetor throat, and the ignited combustible gas mixture slammed into the carburetor due to rapid expansion, making an explosion sound, and sometimes flaming out.
The mixture becomes leaner when accelerating, which is mainly caused by the failure of the carburetor accelerating device..The specific reason is: the acceleration pump piston is worn, damaged or too tight. Acceleration pump inlet / outlet valve is not sealed or blocked by dirt, and the acceleration nozzle is blocked.
The coating thickness tester can nondestructively measure the thickness of the non-magnetic coating on the magnetic metal substrate and the thickness of the non-conductive coating on the non-magnetic metal substrate. The coating thickness gauge has the characteristics of small measurement error, high reliability, good stability, easy operation, etc., and is an essential testing instrument for controlling and ensuring product quality.
The magnetic properties of the base metal generally refer to the influence of the magnetic change of the thickness of the base metal by the magnetic method. In order to avoid the influence of heat treatment and cold processing factors, it is necessary to calibrate the instrument using a standard piece with the same properties as the base metal of the sample, so that it can be used Coat test specimens for calibration.
The electrical properties of the base metal and the conductivity of the base metal have an influence on the measurement, while the conductivity of the base metal is related to its material composition and heat treatment method. Calibrate the instrument using a standard sheet with the same properties as the test specimen base metal. Base metal thickness. Each instrument has a critical thickness for the base metal. Above this thickness, the measurement is not affected by the thickness of the base metal.
