1、 Dongguan CNC processing plant in order to control the machine tool equipment processing safety regulations, the following is about the machine tool system should meet the safety requirements?
1. Easy to operate, reduce walking back and forth, avoid unnecessary bending, tiptoe action.
2. The positioning is accurate and reliable to prevent misoperation when there is a little vibration.
3. The movement direction of the operating parts and the operated parts of the machine tool equipment shall comply with the regulations, and shall be marked with simple symbols< The content of Dongguan CNC processing plant is really good, which is worth paying attention to
4. The necessary interlock mechanism shall be installed to prevent the uncoordinated action of the operating parts and the accident of uncoordinated operation by many people.
5. The structure and arrangement position of handle, hand wheel and button shall meet the requirements. The start button shall be installed in the casing or protected from accidental touch. The handwheel and handle installed on the shaft rod will rotate with the shaft to hurt people during automatic feed, so the automatic disengagement device should be installed.
2、 What are the safety measures to prevent chip from harming human body?
1. According to the properties of the processed materials, Dongguan CNC plant changes the angle of the cutting tool or increases the chip breaking device, selects the appropriate feed rate, and breaks the banded chips into small sections of rolled or massive chips for removal.
2. Install chip remover on the cutting tool, or install shield and baffle on the machine tool to control the chip flow direction and avoid injury.
3. For high-speed cutting of pig iron, copper and aluminum materials, the operator shall be equipped with protective glasses in addition to installing shield and baffle on the machine tool.
4. Use tools to remove the iron filings on the machine tool and the workplace in time to prevent hands and feet from being injured. Do not use hands to pick up the iron filings.
3、 What safety precautions should be paid attention to when machining abnormal and eccentric parts?
When machining abnormal and eccentric parts in Dongguan CNC factory, the work pieces are usually fixed by the flower disk. Therefore, first of all, pay attention to the card firmly. The claw and pressing plate should not extend beyond the diameter of the disc, and it is better to install a shield. Secondly, we should pay attention to the counterweight of eccentric parts. The match is important and appropriate. The clearance between the inner diameter of counterweight and screw diameter should be small. The rotation speed of the machine tool should not be too high, so as to prevent the centrifugal force from moving the counterweight out, colliding with the guide rail of the machine tool, breaking the screw and injuring the operator
4、 What are the four kinds of safety devices for machine tools and what are their functions?
1. Protective device: it is used to isolate the operator from the rotating parts, live parts and harmful substances produced in the process of processing. Such as belt cover, gear cover, electric cover, scrap iron baffle, protective railings, etc.
2. Safety device: used to improve the reliability of machine tools. When a part breaks down or overloads, the safety device will act to stop the equipment or turn to no-load operation. Such as travel limiter, friction clutch, etc.
3. Interlocking device: it is used to control the operation sequence of machine tools and avoid accidents caused by uncoordinated actions. If the lathe screw rod and polished rod can not act at the same time, electrical or mechanical interlocking device should be installed to control.
4. Signal device: it is used to indicate the operation of machinery and equipment, or send out color, sound and other signals when machinery and equipment are abnormal, to remind the operator to take emergency measures to deal with. Such as indicator light, buzzer, electric bell, etc.
5、 What safety precautions should be paid attention to when operating the machine tool?
1. Before work, wear work clothes, cuffs and work caps.
2. Carefully check whether all parts of the equipment, protective cover, limit block, safety screw and other safety devices are in good condition and effective.
3. The equipment must be solidly and effectively grounded to zero, and the voltage of local lighting is 36V.
4. Before operation, oil in each oil hole for lubrication, and work after idling test.
5. When the machine tool is running, it is not allowed to check the surface finish and measure the size of the workpiece by hand.
6. When installing the parts, the spanner shall meet the requirements, and the sleeve shall not be added to increase the torque to tighten the nut< The content of Dongguan CNC processing plant is really good, which is worth paying attention to
7. It is not allowed to wind abrasive cloth by hand to polish rotating parts.
8. Counterweight should be added to eccentric workpiece or abnormal workpiece rotating at high speed, balance test should be done, and shield should be added to protruding part.
9. The power supply must be cut off to replace the gear and load and unload the fixture, and it can only be carried out after it stops steadily
10. Adjust and tighten the stroke limiter before you walk, and dial the feed pistol.
11. When you get off work, put all kinds of knife handles in neutral position, turn off the switch, and clean the machine. "
