Analysis on Innovation Experience of Mechanical Processing Equipment Management

Production equipment is an important tool and means for an enterprise’s production and operation, and it is also a material indicator of the level of social productivity development. The state of equipment technology not only affects the quality of the company’s products, but also affects the economic benefits of the company and the future of the company. Therefore, good management, good use of production equipment, and improvement of equipment management are of great significance to promote the progress and development of enterprises.

The daily management of equipment mainly includes the following: equipment inspection management; equipment lubrication management; equipment maintenance management; spare parts management and safety management.

1 Equipment inspection

Equipment inspection refers to the inspections performed by operators or maintenance workers on the equipment with visual inspection and simple test tools within a specified time according to the inspection items of the equipment maintenance account in order to maintain the specified performance of the equipment. Kind of inspection method. Spot inspection and daily maintenance have the following advantages: it can discover hidden dangers of equipment in time, eliminate faults in the bud, and prevent further deterioration of equipment parts and equipment accidents. Through the accumulation of inspection data, we constantly sum up experience, improve maintenance standards, maintain stable equipment performance, and extend equipment life. Participating in the daily inspection of the equipment can further grasp and understand the structure and performance of the equipment, and improve the sense of responsibility and the level of equipment maintenance for consciously taking care of the equipment. Spot inspection is one of the main channels for equipment operation information feedback. During the equipment inspection, the individual advocates full participation, and everyone related to the equipment management personnel, operators, and auxiliary personnel should put forward their own opinions, and then standardize and organize the inspection system with strong operability. The content of the inspection can be summarized as follows: There are ten major elements of equipment inspection, including pressure, temperature, leakage, lubrication, abnormal noise, heat, vibration, wear, and slack. They can be used as the basis for inspection and diagnosis. The key parts of equipment inspection include sliding parts, rotating parts, transmission connecting parts, supporting parts, hydraulic transmission parts, and parts corroded by media.

2 Equipment lubrication management

The correct selection of various lubricating materials and lubrication according to the specified lubrication time, location and quantity to reduce friction and wear, so that the equipment has good lubrication is an important guarantee for equipment safety, stable accuracy and efficient operation. Equipment lubrication management work requirements: draw up various management systems, prepare lubrication benchmarks, check the implementation of the lubrication system, and achieve “five determinations” (fixed point, fixed oil, fixed amount, fixed time, fixed person). Instruct the correct use of lubricating oil (grease), the reasonable storage of oil products and the daily maintenance of oil quality. If the equipment is found to be poorly lubricated and cause serious wear, the equipment should be stopped and measures should be taken to improve the lubrication condition in time. We will conscientiously manage the recovery and management of waste oil. Grasp the focus of lubrication work, that is, keep clean, use oil rationally, quantify on time, use proper methods, and prevent leakage and blockage.

3 Equipment maintenance management

Equipment maintenance management can be divided into five methods: after the event (passive) maintenance; preventive (active) maintenance; condition maintenance; improvement maintenance and transformation maintenance five methods, the five methods will be introduced separately below.

3.1 After the event (passive) maintenance

Post-maintenance is also called passive maintenance, which mainly refers to a maintenance activity that repairs the equipment after it is found to have problems. The advantage of this maintenance method is that it does not require advance planning, is simple and easy to implement, and can make full use of the equipment's spare parts.

The physical life of the components and maintenance costs are low. Scope of application: For equipment that is not important in production or can be substituted, post-event (passive) maintenance can be used.

3.2 Preventive (proactive) maintenance

Preventive maintenance is also called active maintenance. This maintenance method is to prevent equipment performance degradation or reduce the probability of equipment failure, maintenance activities carried out according to a predetermined plan. The advantage of proactive maintenance is that the maintenance is usually determined according to the operating time of the equipment

Time period. Scope of application: Preventive maintenance should be adopted for equipment that plays an important role in production or whose failure risk is greater than the maintenance risk.

3.3 Condition maintenance

Condition maintenance is a maintenance activity carried out based on the results of equipment condition monitoring. Its essence is the upgrade of preventive (proactive) maintenance. It is a targeted and quantitative maintenance activity. The advantage of conditional maintenance is that it overcomes the non-quantitative factors of preventive maintenance determined by equipment running time, which is beneficial to reduce maintenance costs and reduce preparation work. The scope of application of condition maintenance is: equipment should be equipped with relatively complete detection devices. Condition maintenance is the direction advocated and developed by equipment maintenance management.

3.4 Improve maintenance

The so-called improved maintenance refers to the improved maintenance method of equipment maintenance operations with new technology and new methods. The benefits of improved maintenance: Improved maintenance can greatly promote the improvement of the maintenance level and the quality of equipment maintenance.

3.5 Modification and maintenance

The maintenance activities that modify the structure of the equipment are called retrofit maintenance. The benefits of modification and maintenance: improve the performance of the equipment or enhance the reliability of the equipment. However, we should be cautious about this kind of construction. There should be argumentation and approval beforehand, and evaluation afterwards.

4 Spare parts management

At present, many companies implement the A, B, and C management methods of maintenance spare parts in the management of mechanical equipment spare parts. This method is helpful to ensure the needs of equipment maintenance and improve the reliability, maintainability and economy of the equipment. Spare parts that have a long cycle (slow turnover speed), high importance, fewer spare parts, difficult procurement and manufacturing, and higher prices are Class A spare parts. Class A spare parts should be controlled with emphasis, and should be ordered and purchased or processed in accordance with the most economical and reasonable use demand and time under the premise of ensuring supply to ensure normal production requirements. The control of B-type spare parts is not as strict as that of A-type spare parts, and the control of order batch, time and inventory can also be slightly looser than that of A-type spare parts. The consumption of C-type materials is not too large and there are many varieties. It is often possible to order one time according to the planned demand, or to extend the order interval appropriately to reduce the number of orders. There are a large number of spare parts in the spare parts warehouse. In the implementation of the A, B, and C classification management method, timely feedback of information has become a vital part. The management personnel of the spare parts warehouse should pay attention to the feedback of two aspects of information to the relevant departments: the information feedback of the minimum reserve and the information feedback of the spare parts warehousing.

5 Security Management

Safety management includes the management of personal safety and equipment safety. The production must be people-oriented. The safety of equipment management is also a guarantee of personal safety to a certain extent, and many of the above managements are aimed at equipment safety, so safety management will not be elaborated.
