Installation and debugging of the hose crimping machine

Installation and debugging of the hose crimping machine

Installation and debugging of the hose crimping machine Installation and debugging of the hose crimping machine Handling: The pipe buckle machine is suitable for forklift transportation, and the bottom of the pipe buckle machine is stressed. The pipe buckle machine is strictly forbidden to be inverted. It is strictly forbidden to lift the head of the buckle tube, motor and electrical box. Installation: The hose crimping machine must be placed horizontally on a stable foundation and grounded. Oil filling: Open the oil tank cover and add 68# anti-wear hydraulic oil to the 2/3 position of the oil level gauge. Electricity connection: 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 is inconsistent with the marked direction, please change the position of two of the power cords. Micrometer: used to adjust the shrinkage of the crimping hose, press in more than 1mm counterclockwise half a week, and less than 1mm in clockwise half a week. Pressure adjustment: The maximum pressure of the pipe buckle machine 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). Mold opening speed adjustment: the speed of mold opening speed is controlled by the diverter valve. It is adjusted clockwise, the opening speed is increased, and the counterclockwise adjustment is adjusted. The opening speed slows down, but the opening speed is too fast to increase the noise. The best value is not more than 10Mpa (it has been adjusted before leaving the factory, you can adjust it yourself if necessary).

How to solve when the pressure of the crimping machine is insufficient

How to solve when the pressure of the crimping machine is insufficient

How to solve when the pressure of the crimping machine is insufficient In the work of the withholding machine, sometimes we encounter the phenomenon of insufficient pressure of the withholding machine. At this time, we need to analyze the withholding machine according to the on-site situation to eliminate related faults in time to ensure that the withholding operation continues. 1. The pump is faulty Eliminate the failure of the pump body or replace it with a new pump; 2. The pump is not adjusted to working condition; Let skilled workers re-adjust the pump; 3. Poor work or damage of the overflow valve; Repair or replace the overflow valve 4. Oil leakage of parts and components; Repair or replace the leaking part; If you still cannot find the cause after performing the above failure analysis, you must contact the manufacturer in time for further failure analysis of the equipment. 5. After the crimping machine has been used for a long period of time, there may be a phenomenon that the crimping machine cannot rebound after being compressed, which hinders the work progress. At this time, we must promptly investigate the problem according to the situation. Crimping machines are generally hydraulically driven, so there is no problem such as spring failure. The most likely problem is the solenoid valve that controls the pressure. In the case of improper maintenance, the solenoid valve may fail due to excessive oil pollution. Under normal circumstances, as long as the solenoid valve is disassembled and the dust, oil and other impurities on it are cleaned, it can be restored to work. If the problem cannot be solved, it depends on whether the solenoid valve is damaged. If it is damaged, replace the solenoid valve to solve the problem. If the related problems cannot be solved after the above operations, you should call the manufacturer of the equipment.

Safety Operation Rules For Crimping Machine

Safety Operation Rules For Crimping Machine

Safety operation rules for crimping machine Safe operation regulations 1. The electrical box of the crimping machine must not be opened at will. See an electrician if you have something to do. 2. After the machine is stopped using, the main switch of the power supply must be turned off. 3. The machine must be shut down when changing molds (special attention). 4. The inclined surface between the eight-lobe seat and the front end plate should be kept clean frequently. Metal chips and other hard objects should not stick to the inclined surface. Lubricating oil must be injected to maintain lubrication before starting the machine every day. 5. The positioning screw on the module must be checked frequently for looseness. The positioning screw must be tightened before installing the module. 6. Pay attention to the safety of your hands when using the automatic pipe buckle machine to buckle the pipe fittings. 7. It is better to adjust the micrometer with one hand when the pipe is pressed by the pipe buckle machine, and do not touch the machine with the rest of the body. 8. Before starting the machine, check whether the wires and terminals of the micrometer adjuster are in reliable contact. When the micrometer adjuster is adjusted from large to small, the lock block of the crimping machine must be released first to avoid human failure. 9. The crimping machine must have a dedicated person responsible and maintenance, and the operator must be familiar with the operation process of the crimping machine. 10. Operators are not allowed to test pressure on anything other than the hose. 11. If there is any unexpected phenomenon during the operation, the machine should be shut down immediately, and the relevant personnel should be checked and repaired. 12. After withholding, turn off all power supplies and lock the control box.
