How to use the crimping machine correctly? We can often see crimping machines in some places. How does it crimp? When the user is crimping the high-pressure pipe, if the crimping amount is too small, and the pressure between the joint and the hose is too loose, the crimping hose may come out of the joint at the early stage of use under the action of oil pressure. If the crimping amount is too large, then If the joint and the hose are pressed too tightly, it is easy to cause partial damage to the inner layer of the hose, resulting in cracks. The hydraulic oil will directly enter the steel wire layer from the rupture, and then leak out along the gap between the steel wires to the end of the outer jacket, or flow along the steel wire layer. It accumulates somewhere, causing the outer layer of glue to bulge or even break. When the crimping machine is crimping, the crimping speed should not be too fast, which will easily cause damage to the inner rubber and breakage of the steel wire layer, which will damage the hose prematurely during use. In actual work, when replacing the high-pressure hose, the length of the selected hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the degree of bending of the hose should be minimized. Most of the damage of the high-pressure hose is caused by improper production. . 1. Handling: The pipe pressing machine is suitable for forklift handling, and the pressure is applied to the bottom of the pipe pressing machine. It is strictly forbidden to lift and buckle the machine head, motor and electrical box parts. 2. Installation of the pipe press: The pipe press must be placed horizontally on a stable foundation and grounded. 3. Oil filling: Open the oil tank cover and add 68# anti-wear hydraulic oil to the 2/3 position of the oil level gauge. 4. Connect power: connect the power cord to the power supply specified by the tube press, start the motor and observe the direction of rotation. The direction of the motor should be consistent with the direction marked by the motor. If the direction of the motor of the pipe press is not the same as the direction indicated, please change the position of two of the power cords. 5. Micrometer: It is used to adjust the shrinkage of the crimping hose. It is 1mm more in the counterclockwise half a week, and 1mm less than the clockwise half a week. 6. Pressure adjustment: The maximum pressure of the pipe press system is 31.5Mpa, which is adjusted by the overflow valve. The clockwise adjustment pressure increases, and the counterclockwise adjustment pressure decreases (it has been adjusted at the factory, and can be adjusted by itself if necessary). 7. Mold opening speed adjustment: The mold opening speed is controlled by the diverter valve and adjusted clockwise. The opening speed is accelerated, and the opening speed is adjusted counterclockwise. The opening speed is slowed down, but the opening speed is too fast and the noise will increase. , The best value is not more than 10Mpa.
