JQMT Shearing Machine Frequently Asked Questions

I. Operation - related Questions

Question 1: How to correctly set the shearing dimensions of the shearing machine?

Answer: First, locate the dimension - setting area on the operation panel. Use the numeric keys to input the required shearing length or width values. For some models of JQMT shearing machines, you may also need to use the arrow keys or the confirmation button to switch the input mode. After inputting, be sure to double - check the accuracy of the values. At the same time, ensure the accurate positioning of the material to guarantee that the actual shearing dimensions match the set dimensions. For example, when shearing rectangular sheets, align the edges of the sheet with the positioning markings on the worktable of the shearing machine.

Question 2: Can the shearing speed of the shearing machine be adjusted? If so, how to operate?

Answer: The shearing speed of most JQMT shearing machines can be adjusted. Look for the speed - adjustment button or menu option on the operation panel. Usually, there are "+" and "-" buttons to increase or decrease the speed. Some high - end models may also provide a precise numeric input method to set the shearing speed. When adjusting the shearing speed, determine the appropriate speed according to the thickness and material of the sheet to be sheared. Generally, thicker materials or materials with higher hardness are suitable for a lower shearing speed to ensure the shearing quality and the stability of the equipment.

II. Maintenance - related Questions

Question 1: How often does the shearing machine need a comprehensive lubrication?

Answer: It is recommended to conduct a comprehensive lubrication of the shearing machine every 80 - 100 hours of operation. The lubrication parts mainly include the transmission parts of the blades, guide rails, and all movable joints. Use the lubricating oil recommended by JQMT and operate according to the lubrication points and lubrication methods specified in the equipment manual. For example, for the lubrication of the guide rails, evenly apply the lubricating oil on the surface of the guide rails, and then manually move the slider back and forth several times to fully distribute the lubricating oil.

Question 2: How to clean the blades of the shearing machine?

Answer: First, cut off the power supply and ensure that the equipment is in a safe state. Then, gently wipe the surface of the blades with a soft cloth or brush to remove attached iron filings, oil stains, and other impurities. For stubborn stains, a special cleaning agent can be used, but be careful to avoid the cleaning agent coming into contact with the electrical components of the equipment. After cleaning, dry the blades with a clean cloth and apply an appropriate amount of rust - preventive oil to prevent the blades from rusting.

III. Troubleshooting - related Questions

Question 1: What should be done if the blades of the shearing machine get stuck during the shearing process?

Answer: This may be caused by various reasons. First, check if the blades are worn or damaged. If the blades are severely worn, they need to be replaced in a timely manner. Second, check if the material to be sheared exceeds the rated shearing capacity of the shearing machine. If so, replace it with a suitable material. In addition, check if the transmission system is loose or blocked by foreign objects. If the transmission belt is loose, adjust its tightness; if there are foreign objects blocking, clean them. For example, iron filings and other debris may enter the transmission chain, causing jams. In this case, carefully clean the chain and the surrounding area.

Question 2: What causes abnormal noise when the shearing machine is running?

Answer: Abnormal noise may come from multiple aspects. One is insufficient lubrication. If the lubrication points mentioned above are not lubricated in a timely manner, it will cause increased friction between components and generate noise. In this case, lubrication should be carried out as required. The second is loose machine parts, such as loose screws and worn - out bearings. Check and tighten the loose screws, and replace the severely worn - out bearings in a timely manner. The third is that there may be interference between the material and the blades or the worktable during the shearing process. Check if the material is placed correctly to ensure that the material is stable during the shearing process without shaking or collision.

IV. Safety - related Questions

Question 1: What are the basic safety precautions when operating the shearing machine?

Answer: Before operation, be sure to wear personal protective equipment, such as safety helmets, protective gloves, and safety goggles. During the operation of the equipment, it is strictly prohibited to bring hands or other parts of the body close to the blades and transmission parts. At the same time, ensure that the working area is clean and free of debris to avoid tripping or affecting the operation. In addition, non - professional personnel should not disassemble or repair the equipment at will. If any abnormalities are found in the equipment, stop it immediately and notify professional maintenance personnel.

Question 2: Under what circumstances should the emergency stop button of the shearing machine be used?

Answer: In case of sudden dangerous situations, such as someone's body part accidentally approaching the blade, the equipment emitting serious abnormal noise or vibration, or the electrical system smoking, etc., the emergency stop button should be pressed immediately. After pressing this button, the shearing machine will quickly stop all operating actions to avoid the occurrence or expansion of accidents. After the emergency situation is handled, a comprehensive inspection of the equipment is required. Only after confirming that there are no problems can the equipment be restarted.
