What is the working principle of the locking pipe machine?
Locking Pipe MachineIt is a device that uses hydraulic transmission technology for pressure processing, capable of completing various forging and pressure forming processes. For example, forging steel, forming metal structural parts, and pressing plastic and rubber products. The locking pipe machine is one of the earliest machines to use hydraulic transmission. Currently, hydraulic transmission has become the main form of drive for locking pipe machines. In heavy machinery manufacturing, aviation, plastic, and non-ferrous metal processing industries, the locking pipe machine has become an important piece of equipment.
The hydraulic transmission system of the locking pipe machine primarily converts pressure, with high system pressure, large flow, and high power. Therefore, special attention should be paid to improving the power utilization of the prime mover, preventing impacts and vibrations during pressure release to ensure safety and reliability.
According to the requirements of the pressing process,Locking Pipe Machinethe main cylinder can complete the basic work cycle of rapid descent, deceleration pressing, pressure holding, pressure release, return, and stopping (at any position), with adjustable pressure, speed, and holding time. The ejection hydraulic cylinder is mainly used for ejecting workpieces, requiring ejection, return, and stopping. For example, when the sheet is being stretched, auxiliary actions such as lifting, stopping, and pressure return of the ejection hydraulic cylinder are needed. Sometimes, a trimming cylinder is required to prevent wrinkling around the edges.
The main specifications of the locking pipe machine are the maximum pressure (tonnage) that the main actuator (main cylinder) can output during the main motion, which has been standardized. The tonnage of the lifting oil cylinder is usually 20%-50% of the main oil cylinder. The ejection cylinder of the locking pipe machine can be about 10% of the main tonnage. The trimming cylinder of a double-acting locking pipe machine generally accounts for about 60% of the tonnage of the stretching cylinder.
The speed of the main cylinder is determined by the requirements of the pressure processing technology. Generally, in hydraulic systems where the pump directly supplies oil, the working stroke speed does not exceed 50 mm/s, the fast forward speed does not exceed 300 mm/s, and the fast return speed of the locking pipe machine is equal to the fast forward speed.
AllLocking Pipe Machineare hydraulic devices used to secure hydraulic pipe joint assemblies. The oil pump outputs hydraulic oil under the drive of the motor, pushing the plunger in the retention cylinder to compress the hose joint sleeve, thereby securing the hose.
