How to identify good and bad elbow bending machine factory Sichuan harmonic details for you mechanical Tips

How to identify good and bad elbow bending machine factory [Shu] details for you harmonic mechanical bender little knowledge of how to identify the time of purchase is to choose an important condition for its quality bender. Bending machine mainly used in the furniture industry, steel plants, air conditioning plants, shipyards, Fluids, iron, bathroom, etc. industries. Bender is good or bad, mainly to see you are using a kind of bending machine, bending machine, there are two most used, namely on the market today: hydraulic type and electric type pipe bender bender. Hydraulic pipe bender hydraulic pipe bender into simple (like a bow and arrow type) and desktop hydraulic mandrel bender (like lathe type), hydraulic pipe bender type biggest problem is the oil spill and angular error, and bushings loose, sealed well and so on. Hydraulic bending machine is mainly used for electric power construction, the public railway construction, boilers, bridges, ships, furniture, decoration and other aspects of the pipeline and build, with a multi-function, reasonable structure, simple operation, easy to move, the advantages of rapid installation. (1) The motor starts working lines and parallel lines cut pipe work, when you press the start button QA 1, the motor work, pipe cutting action does not occur. Only then press the start button QA 2 to carry out normal cutting pipe work. (2) In order to tune the machine safety and convenience, when the motor is not working, as long as the instruction issue pipe cutting - press the start button QA 2, pipe cutting operation can be performed sequentially. (3) pipe cutting operation of a motor cycle time is the time delay relay SJ time, from the press QA2, has been to relay the normally closed contacts open date, time delay relay can be adjusted in the range of 0 ~ 40s . Electric bender into pure electric bender and CNC electric bending machine, bending machine two very different, the former is a purely electric bender control error is large, easy to damage the motor, this products are mostly made in China; the latter is the Italian foreign electric CNC tube bender, the biggest problem is the efficiency of the slower, one day can be bent up to approximately 300 tubes
