What Is a Brake Press Operator?
The press (including punch and hydraulic press) is a versatile press with a compact structure. With a wide range of uses and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. It is processed into parts by applying strong pressure on the metal blank to plastically deform and break the metal. When the mechanical press is working, the electric motor drives a large pulley (usually also a flywheel) through a V-belt, and drives the crank slider mechanism through the gear pair and the clutch, so that the slider and the punch die go straight down. After the mechanical press is completed, the slider travels upward, the clutch automatically disengages, and at the same time, the automaton on the crank shaft is turned on, so that the slider stops near the top dead center.
- The press drives the working mechanism by the motor through the transmission mechanism, and applies process force to the workpiece. The transmission mechanism is a belt transmission and gear transmission reduction mechanism; the working mechanism is divided into a screw mechanism, a crank link mechanism and a hydraulic cylinder.
- Incorrect press operation or stamping die setting is the number one cause of press damage and downtime. Proper training of press operators and die setters can ensure that they operate in the correct process. This will quickly reduce downtime.
- Fill the manipulator with brake oil at each point of the manipulator before each shift operation. Use a grease gun to fill an appropriate amount of 20-30 mechanical oil every day before the shift, and use the oil gun to lubricate the clutch once a day before shift. . Clean the machine before each shift.
- Check the fasteners to make up for missing external parts. Check the clutch, spring and belt. Check each lubricating device of the machine tool. Check the electrical wiring for damage and aging, and whether the motor and solenoid are normal. Check crankshaft
- After the press is transported to the installation site, the user opens the packaging box, and then performs the installation work according to the instructions. The press is placed on the cement foundation, and the level is checked on the workbench of the fuselage. It is required to allow 0.20 mm per 1,000 mm of length, and if there is unevenness, adjust with iron until it meets the requirements. The foundation map is shown in Figure X. After the cement is solidified, the foot screw manager (M24) should be evenly tightened, and the level of the fuselage workbench should be checked with a spirit level. The press must be completely solidified on the foundation before it can start working. After the press is installed, the rust oil on the surface of the press should be carefully washed away with kerosene.
- The kerosene should not fall on the painted surface, so as not to damage the paint. Should carefully clean the shoulders and depressions, wipe dry with cotton yarn after cleaning, and apply a thin layer of lubricant. And check whether each lubrication hole is unobstructed, and it must not be blocked.
- After installation, the press should be installed with a reliable ground wire.

- Pre-shift maintenance of press
- (1) Check whether the oil pool, oil level and oil standard meet the required standards. If not, replenish the oil in time.
- (2) Check whether the button is flexible and has no jamming.
- (3) Check if the motor ground wire is loose, detached or damaged. If there is looseness, it should be fastened, and if it comes off or damaged, the maintenance personnel should be notified to deal with it.
- (4) Check whether the safety protection device is complete and reliable.
- (5) Check whether each handle is flexible.
- (6) Tighten the nuts of all parts that are loose.
- Maintenance during press shifts [1]
- (1) Uneven loading
- There is residual gas in the system, you can operate according to the content in the third item, and loosen the tubing joint at the lower part of the cylinder back.
- (2) Oil pump motor does not work
- Replace the fuse.
- (3) The display does not show
- Replace the fuse
- Remove the rear cover and check whether the power cord is firmly connected.
- (4) The display screen is abnormal
- After power failure, open the rear cover and check whether the sensor input connector is reliable. If it is intact, check whether the sensor is normal. [2]
