Introduction of daily maintenance knowledge of high speed hacksaw blade

Apr 17, 2021

Machines and people need regular maintenance to function. Otherwise, it will occasionally lose its temper. The same is true for cold cutting saws, which need regular maintenance by users.

1. 10 checks per day:

(1) Check whether there are water and oil debris around the equipment, and clean it in time;

(2) Check whether there are iron scraps and other sundries at the position of equipment and fixture, and clean them in time;

(3) Lubricating oil should be added to the guide rail and sliding block. Pay attention not to add dry oil. Clean the iron chips on the guide rail every day;

(4) Check whether the oil pressure and air pressure are within the specified range (pressure gauge of hydraulic station, air pressure of clamp cylinder, air pressure of speed measuring cylinder and air pressure of pinch roll cylinder);

(5) Check whether the bolts and screws on the fixture are loose;

(6) Check the fixture cylinder or cylinder for oil leakage, air leakage and rust, and replace it in time;

(7) Check the wear of the saw blade and replace it according to the situation（ Due to the different material and cutting speed, it is recommended to determine whether to replace the saw blade according to the quality of the incision and the sound of sawing. The diameter, tooth number and thickness of new saw blade should be confirmed（ 8) Check the position and wear of steel brush, adjust or replace in time;

(9) The linear guide rail and bearing shall be cleaned, iron chipped and oil added every day

(10) Check whether the pipe diameter, wall thickness and steel pipe length are set correctly, and calibrate the pipe length once a day;

2. Regular maintenance items:

(1) N20 ~ N32 at 1 thin oil lubrication pump;

(2) Feed bearing seat position 2. Calcium based lipid was supplied once a month;

3. Replenish calcium base grease every 10 days at gear rack 1;

4. Regularly clean the iron filings and impurities in the water tank, and keep the coolant clean, generally not more than 10 days;

3. Inspection items every six months:

(1) Check the sliding surface for scars, wear and excessive wear;

(2) Check whether the air pressure piping and the joints are damaged;

(3) Check the cleanliness of the oil pump in the hydraulic station, thoroughly clean and replace with new hydraulic oil;

(4) Check the cleanliness of the oil in the gearbox, thoroughly clean and replace with new gear oil;

4. Precautions:

(1) After changing the specifications, confirm whether the limit speed of flying saw J meets the production speed;

(2) In the automatic state, it is forbidden to clear the length and modify the system parameters;

(3) When modifying the set length online, the speed of the production line should be reduced;

(4) The supporting rods before and after the fixture cannot be adjusted too tightly, which may cause the fixture unable to clamp the steel pipe;

(5) Avoid cutting open tube;

(6) Do not stop the machine when sawing;

(7) The control power is cut off after the automatic mode is exited;

(8) Pipe bending will affect the cutting, straighten as soon as possible;

(9) Turn off the flying saw when changing the tube type and adjusting the machine;

(10) There should be enough cooling water on the saw blade for cooling;

(11) During on-line production, pay attention to observe the fluctuation of production line speed, and the fluctuation should be within the required range
