Description

Technical Field

[0001] The present application relates to the field of numerically controlled sawing machines, and in particular to a feeding structure of numerically controlled sawing machines. Background Art

[0002] The sawing machine uses circular saw blades, saw bands or saw blades as cutting tools to saw metal round materials, square materials, pipe materials and profiles. The processing accuracy of the sawing machine is generally not very high. It is mostly used in the material preparation workshop to cut various bars, pipe materials and other profiles. The saw blade is driven by the driving wheel and the driven wheel. The saw blade cutting direction is controlled by the guide rail control frame. The band saw blade is adjusted and straightened by adjusting the self-rotating bearing. The sawing is swept away by the sweeper. The guide rail control frame is supported by the hydraulic cylinder piston rod to fall into the sawing material. The band sawing machine is equipped with a manual or hydraulic cylinder clamping and locking mechanism, as well as a hydraulic operating valve switch, etc.

[0003] When the existing CNC sawing machine is working, since the height of the equipment is not the same, it is necessary to adapt to the feeding mechanism of different heights. However, the height of the feeding mechanism in the prior art is mostly not adjustable, resulting in low applicability of the feeding mechanism, wasting production costs, and the metal raw material is prone to deviation during the feeding process, especially when feeding metal round materials and metal pipe materials, which is easy to cause the material to roll, resulting in reduced feeding efficiency and poor sawing quality;

[0004] In view of the above-mentioned related technologies, the inventor believes that the feeding structure of the CNC sawing machine has the defects of being difficult to adjust the height of the feeding device and the metal raw material being easily offset during the feeding process;

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0009] Preferably, the side surface of the main board is fixedly connected to the first motor, the inner side wall of the main board is rotatably connected to a screw, and one end of the screw passes through the main board to its side surface and is fixedly connected to the output end of the first motor, and the outer surface of the screw is screwed together with the two limit frames.

[0010] Preferably, the inner side wall of the main board is fixedly connected to a limiting column, and the outer surface of the limiting column slides relatively with the two limiting frames.

[0011] Preferably, four mounting blocks are fixedly connected to the upper surface of the base plate, and the side surfaces of two opposite mounting blocks are rotatably connected to rotating shafts, and the outer surfaces of the two rotating shafts are fixedly connected to worm gears, and two second motors are fixedly connected to the upper surface of the base plate, and one end of the two worm gears passes through the two mounting blocks to their outsides and is fixedly connected to the output ends of the two second motors.
