Description

Technical Field

[0001] The utility model belongs to the technical field of sawing machines, in particular to a servo electric cylinder lifting structure for a band sawing machine. Background Art

[0002] A band saw is a machine tool used for sawing various metal materials. It is mainly used for sawing various alloys and metal materials such as carbon structural steel, low alloy steel, high alloy steel, special alloy steel, stainless steel, acid-resistant steel, etc. Its basic structure includes a machine base, on which a frame body is arranged. A driving disk and a driven disk are arranged on the left and right sides of the cutting frame body. Saw blades are wound around the outside of the driving disk and the driven disk. The saw blade and the driven disk are driven to rotate by the rotation of the driving disk. The workpiece to be cut is placed under the saw blade, and the driving disk, the driven disk and the saw blade are driven downward to complete the cutting of the workpiece.

[0003] At present, the sawing machines on the market all have only one hydraulic system. The same hydraulic system controls multiple hydraulic devices such as feeding, clamping workpieces, cutting feed, etc. When multiple hydraulic devices are controlled by one hydraulic system, due to the different pressures and pressure times required by each hydraulic device, sometimes it is necessary to supply hydraulic oil to multiple hydraulic devices at the same time, resulting in unstable oil supply pressure; sometimes when supplying oil to a hydraulic device, when another hydraulic device also needs oil supply, the oil supply pressure of the hydraulic device that was previously normally supplied with oil will suddenly decrease, resulting in the speed change of the sawing machine during the cutting process, which will affect the cutting accuracy or damage the saw blade on the sawing machine. Among them, the hydraulic equipment for controlling the cutting feed is particularly important for accuracy. At present, the sawing machines on the market with a single hydraulic system cannot control the cutting feed very accurately, and are easily divided by other hydraulic devices during the cutting feed process, resulting in sudden speed increases and decreases in the cutting feed division pressure, affecting the service life of the saw blade.
