How to use the hose crimping machine?

Hose crimping machine is a common tool in rubber pipe installation engineering. However, many people do not understand the precautions for the use of hose crimping machine. As a professional crimping machine manufacturer, we will introduce the precautions for the use of hose crimping machine.

When the hose crimping machine crimps the hose joint: the crimping size is too much, the rubber layer inside the hose is broken, causing oil leakage; the crimping size is too small, causing oil leakage and being hydraulically pressed out of the joint. Be sure to grasp the degree of crimping of the fair, the shrinkage of the inner hole of the joint core is subject to the standard, the GB joint is compressed by 0.1~0.4mm, and the common joint is compressed by 0.1~2mm.
For example, a Ф19mm four-layer steel wire hose is used. The outer diameter of the joint outer casing is 37mm before the crimping and 33.5mm after the crimping. The inner diameter of the mold should be Ф33mm, and the corresponding micrometer scale is 3. Install the Ф33mm mold on the mold base, and rotate the micrometer scale to 3 places, and then peel the hose and assemble it with the joint. After the crimping is completed, the outer diameter of the joint is measured. The value of the crimping parameter table is 33.5 mm, and the crimping is completed. If the outer diameter does not match after the crimping, fine-tune the micrometer and then press the next hose.
Mold opening speed adjustment: the speed of the mold opening speed is controlled by the diverter valve, clockwise adjustment, the opening speed is increased, the counterclockwise adjustment is made, the opening speed is slowed down, but the opening speed is too fast, the noise is increased. The optimum value is not more than 10Mpa (it has been adjusted at the factory and can be adjusted if necessary).

Pressure adjustment: The maximum pressure of the tube press system is 31.5Mpa, which is adjusted by the relief valve. The pressure is increased clockwise, and the pressure is reduced counterclockwise (it has been adjusted at the factory and can be adjusted if necessary).
Micrometer: used to adjust the amount of shrinkage of the crimping hose. Press 1mm counterclockwise for half a week and 1mm for half a week clockwise.
Power connection: Connect the power cable to the power source defined by the pressure tube machine, start the motor to observe the steering, and the motor steering should be consistent with the direction marked by the motor. If the motor is not in the same direction as the marked direction, please change the position of the two power cords.
Installation: The tube press should be placed horizontally on a stable foundation and grounded.
Filling: Open the fuel tank cap and add 68# anti-wear hydraulic oil to the oil level 2/3 position.
Handling: The hose crimping machine  should be handled by a forklift, and the bottom of the pipe press should be stressed. The pipe press must not be reversed. It is strictly forbidden to lift the pressure pipe head and the motor and electrical box parts.
