Safety operation procedures
1. Before starting work, check whether the electric, hydraulic and pneumatic power supplies are disconnected. Hang a warning sign at the switch that says "maintenance is under way, no starting". If necessary, the distribution box should be locked or supervised by a special person. If the machine and power supply are not cut off, it is forbidden to work.
2. When disassembling the side parts, such as the box cover of the gearbox, the lower screw should be removed first, and the upper screw should be tightened first when assembling. When removing parts with unbalanced center of gravity, remove the screws far away from the center of gravity first, and then install the screws close to the center of gravity. When disassembling the spring, attention should be paid to prevent the spring from collapsing and hurting people.
3. The disassembled parts should be put together as far as possible and placed safely according to the regulations. Don't throw them about. If there is a rotating mechanism, it should be stuck to prevent rotation.
4. When moving parts by manpower, personnel should be properly equipped. When many people move and carry, they should be under unified command, and their actions should be consistent when working. When lifting shafts, screws, pipes and girders, they must be shoulder to shoulder. We must be steady, let go, and strive for progress while being steady. When handling machine tools or lifting large and heavy parts, the safety operation procedures of riggers and porters should be strictly observed.
5. When scraping the guide surface of equipment or machine tool, the bottom of the workpiece should be leveled and the joint surface should be kept level. When using the jack, the bearing surface should be firmly padded to ensure safety.
6. During scraping operation, the scraped workpiece must be smooth, and it is not allowed to move in series. Calibration tools must be equipped with fixed bracelets or rings. When two or more people do the same workpiece, be sure to pay attention to the direction of the scraper, and never scratch the human body. During reciprocating grinding, fingers should not extend to the grinding surface, and the running position of the grinding plate should be adapted to its center of gravity, and should not exceed the grinding surface of the workpiece to prevent slipping. During electric grinding, there must be a special person to guard the electric switch or install the interlock device.
7. When using tools, you should operate correctly according to the safety operation procedures of common tools used by locksmiths.
8. The workplace should be kept clean, and oily sewage should not flow on the ground to prevent slipping and hurting people.
9. When cleaning parts, it is forbidden to smoke, ignite or carry out other open flame operations. Do not use gasoline to clean parts, scrub equipment or floor. Waste oil should be poured into the designated container and recycled regularly, and it is not allowed to be poured into the sewer.
10. Before the safety protection devices on the mechanical equipment are installed, it is forbidden to test run and hand over the production.
1 1. When overhauling containers containing toxic, flammable and explosive substances, pressure relief, cleaning, replacement or neutralization must be carried out in advance to remove indoor gas, liquid and slag, and ventilation measures must be taken before operation.
12. Observe the "general locksmith" safety operation regulations.
The main task of the mechanic:
Mainly divided into the following parts: parts processing, equipment maintenance, manufacturing and maintenance.
1, machining parts
Some machining that is not suitable or can't be solved by mechanical methods can be done by fitters. Such as: scribing in the process of machining parts, precision machining (such as scraping templates, making molds, etc. ), inspection and maintenance, etc.
Assembly: according to the assembly technical requirements of mechanical equipment, the parts are assembled, and after adjustment, inspection and debugging, they become qualified mechanical equipment. ?
2. Equipment maintenance
When the machinery fails, is damaged or its accuracy drops after long-term use, it should also be maintained and repaired by the fitter.
3, manufacturing and repair
Manufacture and repair all kinds of tools, fixtures, measuring tools, molds and various professional equipment.
4. Safety matters
(1) The file is a right-handed tool and should be placed on the right side of the vise. When placed on the vise table, the handle of the file should not be exposed outside the vise table, so as to avoid touching the ground and hurting feet or damaging the file.
(2) Files with useless handles or files with cracked handles cannot be used.
(3) When filing, the file handle should not touch the workpiece, so as to avoid the accident caused by the file handle falling off.
(4) Don't blow iron filings with your mouth to prevent iron filings from entering your eyes. You can't touch the filed surface with your hands.
(5) The file shall not be used as a crowbar or hammer.
5. Maintenance
(1) In order to prevent the file from wearing too fast, do not file the hard skin of the blank or the hardened surface of the workpiece with a file, but use other tools or the front end and side teeth of the stand first.
(2) When filing, use one side of the falling knife first, and then use the other side after this side is dull. Because used file teeth rust easily.
(3) When filing, make full use of the effective working face of the file to avoid local wear.
(4) The file cannot be used as a tool for disassembly, knocking and prying, so as to avoid the file being broken due to fragile materials.
(5) When using plastic files and small files, do not use too much force to prevent the knife from breaking.
(6) The file should be waterproof and oil-proof. Files rust easily when they are wet with water. The file is easy to slip when working after being stained with oil.
(7) In the process of filing, if chips are found embedded in the file lines, they should be removed in time to avoid the chips scratching the machined surface. After the file is used up, brush off the remaining debris along the file line with a file brush or copper sheet to prevent rust. Never blow potato chips with your mouth to prevent them from flying into your eyes.
(8) When placing files, avoid collision with hard objects, avoid file overlapping and stacking, and prevent file damage.
Job characteristics:
Fiddler has three advantages (flexible machining, complex shape, high precision parts and low investment) and two disadvantages (low production efficiency, high labor intensity and unstable machining quality).
(1) Flexible machining. When it is not suitable for machining, especially when maintaining mechanical equipment, locksmiths can get satisfactory results.
(2) Parts with complex shapes and high precision can be processed. Skilled fitters can process parts that are more precise and smoother than those processed by modern machine tools, as well as parts with very complex shapes that even modern machine tools can't process, such as high-precision measuring tools, templates, and molds with complicated beginnings.
(3) The tools and equipment used for small locksmith processing are cheap and easy to carry.
(4) Low production efficiency and high labor intensity.
(5) The processing quality is unstable, which is affected by the technical proficiency of workers. ?
Scope of work:
It mainly includes marking, parts processing, assembly, equipment maintenance and innovative technology.
(1) marking lines are used to mark parts before machining.
(2) The manufacturing of parts that are not suitable for machining or can not be solved by mechanical methods, as well as all kinds of tools, fixtures, measuring tools and special equipment, should be completed by locksmiths.
(3) Assembly: According to the technical accuracy requirements of the machine, the processed parts are assembled to make it a complete machine.
(4) Equipment maintenance The parts of mechanical equipment that are damaged, out of order or lose precision after long-term use shall be maintained and repaired by locksmiths.
(5) Innovating technology In order to improve labor productivity and product quality, it is also an important task for locksmiths to continuously carry out technological innovation and improve tools and processes. In a word, locksmith is an indispensable job in the machinery manufacturing industry.
