Safety knowledge you should pay attention to when operating machine tools

The safety of machine tool equipment, such as shears, bending machines and other CNC machine tools, has always been a commonplace issue. Today, let the staff of Nantong Ruhai introduce to you in detail the machine tools based on their many years of experience in producing machine tool equipment. Operational safety knowledge:

1. What safety matters should be paid attention to when processing deformed and eccentric parts?

When processing deformed and eccentric parts, faceplate clamping is generally used to fix the workpiece. Therefore, first of all, pay attention to installing the card firmly. The claws and pressure plate should not extend beyond the diameter of the faceplate. It is best to install a protective cover. Secondly, pay attention to the counterweight of the eccentric parts. The distribution is important and appropriate. The gap between the inner hole diameter of the counterweight and the diameter of the screw should be small. The rotation speed of the machine tool should not be too high to prevent the centrifugal force from moving the counterweight outward during rotation, colliding with the machine tool guide rail, breaking the screws, and injuring the operator.

2. What safety requirements should the machine tool equipment control system meet?

1. Easy to operate, reduce walking back and forth, and avoid unnecessary bending and tiptoeing.

2. The positioning is accurate and reliable, preventing malfunctions caused by slight vibrations.

3. The movement direction of the operating parts of the machine tool equipment and the movement direction of the operated parts must comply with regulations and be marked with simple symbols.

4. Install necessary interlocking mechanisms to prevent uncoordinated movements of operating parts and uncoordinated accidents when multiple people operate.

5. The structure and arrangement of handles, handwheels, and buttons must comply with regulations. The start button should be installed in the casing or equipped with a guard ring to prevent accidental activation. The handwheel and handle installed on the shaft will rotate with the axis during automatic feed, so an automatic ejection device should be installed.

3. What are the safety measures to prevent chips from harming the human body?

1. According to the properties of the material to be processed, change the tool angle or add a chip breaking device, select an appropriate feed amount, break the strip-shaped chips into small pieces of rolled or block chips, and remove them.

2. Install a chip conveyor on the tool, or install a guard or baffle on the machine tool to control the flow of chips to prevent injury to people.

3. For high-speed cutting of pig iron, copper, and aluminum materials, in addition to installing guards and baffles on the machine tool, the operator should wear protective glasses.

4. Use tools to promptly remove iron filings from machine tools and workplaces to prevent injuries to hands and feet. Do not pick up iron filings with your hands.

4. What are the four safety devices equipped with machine tools and what are their functions?

1. Protective device. It is used to isolate the operator from the rotating parts, live parts of the machine and equipment, and harmful substances generated during the processing. Such as belt covers, gear covers, electrical covers, iron filings baffles, protective railings, etc.

2. Safety device. Used to improve the reliability of machine tool equipment. When a component fails or is overloaded, the safety device operates to quickly stop the equipment or switch to no-load operation. Such as stroke limiter, friction clutch, etc.

3. Interlocking device. It is used to control the operating sequence of machine tools and equipment to avoid accidents caused by uncoordinated movements. If the lathe screw and polished rod cannot move at the same time, electrical or mechanical interlocking devices must be installed for control.

4. Signaling device. It is used to indicate the operating status of machinery and equipment, or when machinery and equipment are operating abnormally, it can send out color, sound and other signals to remind the operator to take emergency measures. Such as indicator lights, buzzers, bells, etc.

5. What safety matters should be paid attention to when operating machine tools?

1. Wear work clothes, tie cuffs, and work cap before working. It is strictly prohibited to operate with gloves.

2. Carefully check whether all parts of the equipment and safety devices such as protective covers, limit blocks, and safety screws are intact and effective.

3. The equipment must be firmly and effectively grounded to zero, and the local lighting must be 36v.

4. Before work, add oil and lubrication in each oil hole, and perform an idling test run to confirm that there are no faults before starting work.

5. When the machine tool is running, it is not allowed to check the surface finish of the workpiece and measure the size of the workpiece by hand.

6. When installing parts, the wrench must meet the requirements, and no casing should be added to increase the torque to tighten the nut.

7. Do not use your hands to wrap emery cloth around to polish rotating parts.

8. For high-speed rotating eccentric workpieces or deformed workpieces, counterweights should be added, balance tests should be performed, and protective covers should be added to the protruding parts.

9. When replacing gears or loading and unloading fixtures, the power supply must be cut off and stopped before proceeding.

10. Before automatic tool feeding, adjust and tighten the stroke limiter, and pull out the feed pistol.

11. When leaving get off work, put the various tool feed handles in the neutral setting, pull down the switch, and wipe and clean the machine tool.
