[0004] In the process of use, the hydraulic bypass is usually used to control the amount or size of the oil supply to the hydraulic oil circuit of the plate bending machine, and a filter is set to filter the impurities in the hydraulic oil to improve the working efficiency of the hydraulic oil. After the bypass control system, there will still be a phenomenon that the pressure of the bending machine is suddenly large and small, so that the pressure cannot be applied evenly on the surface of the bent bamboo board, and the phenomenon of uneven bite occurs, which makes the bending uneven, resulting in the bamboo board. The scrap rate is high, and the bamboo boards are wasted; on the other hand, the amount of oil can not be accurately controlled, and the cost is relatively large

The invention discloses an energy-saving plate bending machine for a bamboo board. The energy-saving plate bending machine comprises a plurality of hydraulic circuits connected to a plurality of plate bending devices, and a hydraulic main oil supply pipe for supplying oil to the hydraulic circuits, and further comprises a hydraulic bypass connected to the hydraulic main oil supply pipe, wherein the hydraulic bypass comprises at least two hydraulic branches, and each hydraulic branch is connected to an overflow valve and a filter; in addition, an electromagnetic valve is connected between the overflow valve and the filter on at least one hydraulic branch; each electromagnetic valve is connected to a control circuit of the plate bending machine. According to the energy-saving plate bending machine, the precision for controlling the oil mass of the hydraulic circuits of the plate bending machine is improved, the rejection rate is reduced when the bamboo board is bent by the plate bending machine, and the hydraulic oil consumption is saved, so that the ability of enterprises to manufacture a curved bending plate of the bamboo board is improved to create more benefits and the quality of bamboo board furniture is improved.
Description
technical field [0001] The invention relates to the technical field of bending machines for bamboo boards, in particular to an energy-saving bending machine for bamboo boards. Background technique [0002] The existing hydraulic plate bending machine is used for molding bending of pressed plywood, multi-layer board, solid wood door, steel wood door, bamboo board, etc. [0003] Existing hydraulic plate bending machine adopts hydraulic oil supply pair, and the plate on the frame carries out independent bending bamboo plate at the same time, to obtain the curved shape bamboo plate, use for furniture manufacture. [0004] In the process of use, the hydraulic bypass is usually used to control the amount or size of the oil supply to the hydraulic oil circuit of the plate bending machine, and a filter is set to filter the impurities in the hydraulic oil to improve the working efficiency of the hydraulic oil. After the bypass control system, there will still be a phenomenon that th...
