Reasons and countermeasures for unplanned parking of R535 spinning machine Han Shufa, Zhang Yanhong, Guanzheng Xinxiang Chemical Fiber Co., Ltd., Xinxiang, Henan 453011, China) Unplanned parking during the year The reason for the high number of times and the corresponding countermeasures taken in the installation and maintenance of the model in the sixth filament workshop, that is, to grasp the key processes of the installation and maintenance of the spinning machine, and to strengthen the construction of the workforce is to reduce the spinning machine within one year of production. The root of the number of unplanned stops.
1刖目 R535 spinning machine is currently the main type of viscose filament production enterprise in China. Our company has expanded the second filament workshop from 87 years until the expansion of the sixth filament workshop in 2000. The parts are supplied by many manufacturers and assembled by themselves, which makes the installation work more difficult. At the same time, the number of unscheduled stops of the spinning machine after driving is high. This requires us to have a skilled team of workers to disperse the spinning machine. Assembly and daily maintenance and maintenance ensure that the equipment runs normally and smoothly, and escorts production.
2 Reasons for Unplanned Parking of Spinning Machine The R535B spinning machine that our company installed, commissioned and drove before was put into operation within one year. The unplanned parking was mainly caused by the spindle breaking and rolling keys, followed by other reasons such as burning motor. of.
2.1 Spindle break When the cabinet is installed, the coaxiality adjustment of the spindle is not in place and the coaxiality of the spindle between the installation time zone and the zone of the spinning machine does not meet the installation standard. After the spinning machine is put into normal production, it has been subjected to the rotation of the spindle. The large torque causes the spindle to be twisted to cause the spinning machine to stop. Unplanned parking due to spindle breakage accounts for 60%. 2.2 When the roller key is installed, there is a deviation of the tightening torque of the coupling bolt, the tightening torque is not enough, or the key and the keyway have a large clearance. During normal production, the coupling is loose due to long-term rotation. The key is rolled out of the keyway to cause the spinning machine to stop. Unplanned parking caused by rolling keys accounted for 30*. 2.3 Burning motor power "target=_blank> During the operation of the motor, the temperature rise too fast caused the motor plastic blade to deform and fall off, or the motor quality problems such as bearing oil shortage caused the motor to burn out. Spinning machine parking. Unplanned parking caused by burning motor accounted for 5*. 2.4 Other fasteners loose, high frequency heating of electric spindle, beating of the transmission part of the machine head, vibration or unsynchronization of the wire-wound beam, breakage of the belt of the machine head, etc. It can also cause unplanned parking of the spinning machine, but the probability is very small. These factors together only account for 5* of unplanned parking, and generally do not cause the spinning machine to stop.
3 Countermeasures Analysis The reason why the R535 spinning machine has a high number of unplanned stops during one year of production is ultimately caused by the quality of the installation. Therefore, we focus on strengthening the construction and management of the installation team.
3.1 Develop a lifelong investigation system to uniformly number the installers. When the cabinets are assembled, the respective work numbers will be hit on the cabinet, the responsibility will be clearly defined, and the people will be implemented and the lifelong investigation system will be implemented. The formulation of this system fully mobilized the subjective initiative of the employees, and enabled the employees to actively and consciously do the installation work from the traditional concept of 'you want to do well', which is passively accepted for inspection.
3.2 Improve the accuracy of the spindle flat shaft For the spindle break, the accuracy of the flat shaft of the spindle should be accurate, so that the coaxiality accuracy can meet the installation requirements, thereby reducing the vibration of the box.
3.2.1 Strict box assembly quality, spindle concentricity spindle single-area assembly coaxiality during assembly 3.2.2 Precision flat axis accuracy during assembly of spinning machine, coaxiality between zones and zones 3.2.5 Inspection standard spinning After the machine is assembled, it is required to rotate the spindle without any tools.
3.3 Improve the uniformity of the rolling key. There is a deviation between the tightening torque of the coupling bolt and the tightening torque. We have equipped a special wrench to tighten the bolt diagonally and balance the force to ensure that the tightening torque of the diagonal bolt is uniform and the two gaps are uniform. . For the key and the keyway, the clearance is large, and the unqualified shaft and the coupling are replaced in time to achieve an interference fit.
3.4 Establish supervision and inspection system The technical personnel are responsible for acceptance, check, and unqualified installation quality, and require them to rework until they meet the installation requirements.
Coaxiality between the main shaft area and the area 3.2.3 After the box is in place, the accuracy of the shaft head is accurately calibrated, the coaxiality of the spindle shaft head is 3.5.2, and 114 spinning machines are divided into responsible machines according to the personnel, and it is required to be employed every day. First check the respective responsible machine, and find that the motor heat or other abnormal conditions are reported in time, and take corresponding measures to check and repair the machine without affecting the normal production of the spinning machine to ensure the normal operation of the motor.
3.6 Strengthening the staff's operational skills training and learning is not regularly conducted. Employing experienced masters and technicians to train and lecture on equipment installation, maintenance technology and equipment theoretical knowledge, and regularly conduct theoretical tests on theoretical and practical operations. Multi-faceted comprehensive improvement of the operational skills of the maintenance workers and the comprehensive ability to deal with problems.
3.7 Convene the experience exchange meeting, strengthen the equipment maintenance quality, often hold the maintenance work experience exchange meeting, exchange their experiences in daily work, and sum up the 'four characters' for the daily maintenance of the spinning machine and the minor repair work. ", diligence" diagnosis method. That is to see, smell, listen, touch "and the current equipment is abnormally reported immediately, without affecting the normal production of the spinning machine, can make full use of the replacement of the nozzle car for some bearings, fan pages and other parts in a short period of time. Repair or replace it to ensure the normal operation of the equipment.
Look: Look at the equipment and look at it carefully. You can find the problem at a glance. For example, whether the fuel quantity meets the requirements, whether the wire-wound beam is vibrating, etc.
Smell: All kinds of odors caused by abnormal abrasion of leather parts such as belts and plastics can be found with a nose.
Listening: The gears in the head are not well meshed; the belt is broken, and the transmission parts are beating and other factors can cause the head to be noisy.
Touch: Touch the spindle, the box, etc. by hand to see if it is hot.
4 Conclusion By adopting the above measures, the installation quality and installation speed of the sixth filament workshop have created the most history of our company. The trial production was successful once, and the first batch of products reached the first-class product level on that day. 73%, creating a record of the largest scale, the shortest time, the most capital, and the best quality. Since the car has been running for more than a year, the number of unplanned stops has been much lower than that of the same type of spinning machine that our company installed, commissioned and drove in the past. This fully demonstrates that the key process of installing and maintaining the spinning machine is very good. A responsible workforce is fundamental to reducing unplanned parking.

A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power.[1] The various members such as pulleys and gears are mounted on it.
Transmission shafts are used to transmit power between the source and the machine absorbing power
Spindles are crucial parts for your lawn mower cutting deck that work together with the pulleys and belts to perform clean and even mowing.
Our shaft/ axle/ spindle we made normally applied on the transmissions, lawn mowers, trucks, excavator and other vehicles, etc.
The materials we used are normally mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used.
Shafts are generally formed by not rolling and finished to size by cold drawing or turning and grinding.
Some of the spindles are applied forging castings to save costs.
Main of our customers are from USA, CANADA, AUSTRALIA, German and Chinese domestic market.
