How to operate metal band sawing machine correctly?

1. It is necessary for operators and repairers of metal band sawing machines to undergo professional training to master the operation and repair skills of band sawing machines. The operators must ensure that they are concentrated. Before operation, they should wear tight-fitting protective clothing, the cuffs should be fastened, and the hem of the jacket should not be turned over. Wear gloves, don't put on, take off or change clothes next to the running machine, or wrap it around the body to avoid machine strangulation. It is necessary to wear a safety helmet, the braids should be placed in the hat, and skirts and slippers are not allowed.

2. Do all the preparatory work before starting, and the vise equipment makes the sawing base located in the center of the sawing stroke. The material is placed horizontally on the vise and at right angles to the saw blade; if you want to saw the material at an oblique angle, first adjust the vise to the desired angle, and the size of the saw material should not be larger than the maximum saw material size of the machine tool.

3. The saw blade must be tight and tight, and the speed and feed component must be appropriate. Before sawing, test the machine for 3-5 minutes to blow out the air in the hydraulic cylinder and the oil grooves on the hydraulic transmission equipment, and check whether the sawing machine is faulty and whether the smooth oil circuit is normal.

?4. The swarf wire brush should be adjusted so that the wire touches the bottom of the band saw blade, but not over the base of the teeth. Pay attention to investigate whether the wire brush can remove iron chips.

5. Adjust the guide arm along the dovetail guide according to the size of the workpiece to be processed. After adjustment, it is necessary to lock the guide device.

6. When sawing pipes or sheet profiles, the tooth pitch should not be less than the thickness of the material. When sawing, the handle should be retracted to a slow position and the amount of feed should be reduced.

7. When shifting, it is necessary to park first and then open the protective cover, roll the handle to loosen the belt, place the V-belt in the groove of the required speed, then tighten the belt and cover the protective cover. During the operation of the sawing machine, it is forbidden to change speed halfway.

8. Cast iron, copper and aluminum parts do not add chip lubricating fluid, and other parts must add chip lubricating fluid. It is necessary to use special hydraulic oil and lubricating oil in hydraulic transmission and lubricating equipment, and the coolant must be cleaned and replaced or filtered periodically.

9. The saw blade cracks during the cutting process. After replacing the new saw blade, the workpiece must be turned over and sawed from scratch. The saw bow should be lowered slowly without impact. During the cutting process, the operator is prohibited from leaving the post. When the data is about to be sawed off, it is necessary to strengthen the investigation and pay attention to safe operation.

10. When the operation is over, cut off the power supply, put the operating handles back to the empty positions, and do a good job of cleaning.

11. Add lubricating oil and sufficient coolant according to the rules. When doing empty work, check whether each part is normal. If the machine tool is found to be faulty during operation, it should immediately stop and report that the construction and maintenance department will send a mechanic to repair it.

12. When cutting, do not measure the size and approach the saw blade and saw seam with hands or things.

13. It is necessary to cut off the power supply at the end of each shift. Flip the protective cover over. Scrape off chips, scrub clean, and do the usual maintenance and cleaning of the surrounding environment.
