Safety knowledge that should be paid attention to when operating machine tools

Machine tool equipment, such as shearing machine, bending machine and other CNC machine tool safety issues, has always been a commonplace problem, today let Nantong Ruhai staff, with their own years of experience in the production of machine tools and equipment for you to introduce in detail about the safety of machine tool operation knowledge:

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

For processing deformed and eccentric parts, the workpiece is generally fixed by using a flower disc clamping. Therefore, first of all, we should pay attention to the reliable installation of the card. The claws and pressure plates should not extend beyond the diameter of the flower plate, and it is best to install a shield. Secondly, pay attention to the counterweight of the eccentric parts. Appropriate for the matching. The gap between the inner bore 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, in case the centrifugal force will move the counterweight outward, collide with the guide rail of the machine tool, break the screw, and injure the operator.

2. What safety requirements should be met by the machine tool equipment control system?

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

2. Accurate and reliable positioning to prevent malfunction if there is a slight vibration.

3. The movement direction of the operating parts of the machine tool and the moving direction of the operated parts should comply with the regulations, and there should be simple symbols.

4. Install the necessary interlocking mechanism to prevent the uncoordinated action of the operating parts and the uncoordinated accidents when multiple people operate.

5. The structure and arrangement of handles, handwheels and buttons should comply with the regulations. The start button should be installed in the casing or equipped with a guard ring to prevent accidental touching. The handwheel and handle installed on the axle rod will rotate with the shaft to injure people when the tool is automatically fed, so an automatic ejection device should be installed.

3. What are the safety measures to prevent chip injury to human body?

1. According to the properties of the material to be processed, change the tool angle or increase the chip breaking device, select the appropriate feed, and break the ribbon chips into small sections of roll or block chips and remove them.

2. Install a chip conveyor on the tool, or install a guard and baffle on the machine tool to control the flow of chips without injuring 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 be equipped with protective glasses.

4. Use tools to remove iron filings on the machine tool and in the workplace in time to prevent injuries to hands and feet, and do not pick up iron filings by hand.

Fourth, what are the four safety devices configured with machine tools and equipment, and what is their function?

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

2. Safety device. It is used to improve the reliability of machine tools. When a component fails or is overloaded, the safety device acts, quickly stops the equipment to work or turns into no-load operation. Such as stroke limiter, friction clutch, etc.

3. Interlocking device. It is used to control the operation sequence of machine tools and equipment to avoid accidents caused by uncoordinated movements. If the screw rod of the lathe and the smooth rod cannot operate at the same time, it is necessary to install an electrical or mechanical interlocking device to control it.

4. Signal device. It is used to indicate the operation of machinery and equipment, or when the operation of machinery and equipment is abnormal, it sends out signals such as color and sound to remind the operator to take emergency measures to deal with it. Such as indicator lights, buzzers, electric bells, etc.

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

1. Wear work clothes, tie the cuffs, and wear a work hat before work. It is strictly forbidden 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 and connected to zero, and the local lighting must be 36V voltage.

4. Before working, add oil and lubricate in each oil hole, and confirm that there is no fault before working.

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 the card parts, the wrench should meet the requirements, and the casing should not be added to tighten the nut with a strong torque.

7. It is not allowed to wrap the abrasive cloth by hand to polish and rotate the parts.

8. Counterweight should be added to the eccentric workpiece or deformed workpiece that rotates at high speed, and the balance test should be carried out, and the protruding part should be guarded.

9. The replacement of gears and loading and unloading fixtures must be cut off from the power supply and can only be carried out after the shutdown is stable

10. Before the automatic knife passing, adjust and tighten the stroke limiter, and dial out the feed pistol.

11. When getting off work, put all kinds of handle handles in neutral settings, pull down the electric door, and wipe the machine tool to clean.
