[0017] See also Figure 1-Figure 2The utility model provides a technical solution: a double-column horizontal band sawing machine, comprising a band sawing machine body 1, a fixed frame 11 is slidably connected to the top of the band sawing machine body 1, and also comprises a limit block 12 and a Hall sensor 13. The limit block 12 is welded to the middle part of the bottom side of the fixed frame 11, and a limit groove 14 is horizontally provided in the middle part of the upper surface of the band sawing machine body 1, the limit block 12 is slidably connected to the limit groove 14, and the inner wall of one side of the limit groove 14 is fixedly connected to a servo motor 15 by a bolt 23, and the shaft end of the servo motor 15 is fixedly connected to a screw rod 16, and the outer side of the other end of the screw rod 16 is fixedly connected to a magnetic steel 17, and the Hall sensor 13 is fixedly connected to the inner wall of the bottom end of the limit groove 14, and the magnetic steel 17 is evenly distributed on the outer side of the screw rod 16 in an annular shape, and the magnetic steel 17 is aligned with the Hall sensor 13, and one end of the screw rod 16 is rotatably connected to the inner wall of the other side of the limit groove 14 through a bearing, and the screw rod 16 horizontally penetrates the limit block 12 and is threadedly connected to the limit block 12.

[0018] In this technical solution, the servo motor 15 is controlled to work, which can drive the screw rod 16 to rotate. During the rotation of the screw rod 16, the limit block 12 can be driven to move left and right in the limit groove 14, thereby driving the fixed frame 11 to move on the upper surface of the band saw bed body 1 to adjust the cutting position of the metal material. During the rotation of the screw rod 16, the magnet 17 can be driven to rotate. When the magnet 17 rotates to the bottom side of the screw rod 16 and is vertically aligned with the Hall sensor 13, the Hall sensor 13 can transmit data to the corresponding controller. The corresponding controller can detect the number of rotations of the screw rod 16, and further detect the displacement of the fixed frame 11 and the metal material, thereby detecting the cutting position of the metal material. When the cutting position of the metal material reaches the specified position, the corresponding controller can automatically control the servo motor 15 to stop working, thereby automatically controlling the cutting position of the metal material.

[0019] In this embodiment, a clamp block 2 is slidably connected to the inner side of the fixing frame 11 , an electro-hydraulic push rod 21 is fixedly connected to one side of the fixing frame 11 via a bolt 23 , and a telescopic end of the electro-hydraulic push rod 21 is fixedly connected to the other side of the clamp block 2 .

[0020] In this technical solution, the electro-hydraulic push rod 21 is controlled to work, so as to push the clamping block 2 to move in the fixing frame 11, and metal materials of different sizes can be clamped.

[0021] In this embodiment, a clamping groove 22 is formed on the inner wall of one side of the clamping block 2 and one side of the fixing frame 11 , and a bolt 23 is vertically penetrated through the inner wall at the top end of the clamping groove 22 and is threadedly connected thereto.

[0022] In this technical solution, the two ends of the metal material can be limited by the clamping groove 22, and the bolts 23 are rotated and pressed against the upper surface of the metal material to fix the two ends of the metal material, thereby improving the stability of the metal material during cutting.

[0023] When a double-column horizontal band sawing machine is in use, the electro-hydraulic push rod 21 is controlled to work, which can push the clamping block 2 to move in the fixing frame 11. Through the clamping groove 22 on the outer side of the clamping block 2 and the inner wall of the fixing frame 11, the two ends of the metal material can be limited and clamped. The bolt 23 is turned and pressed against the upper surface of the metal material to fix the two ends of the metal material, thereby improving the stability of the metal material during cutting. The servo motor 15 is controlled to work, which can drive the screw rod 16 to rotate. During the rotation of the screw rod 16, the limit block 12 can be driven to move left and right in the limit groove 14, thereby driving the fixing frame 11 on the upper surface of the band sawing machine body 1. The surface moves to adjust the cutting position of the metal material. During the rotation of the screw rod 16, the magnet 17 can be driven to rotate. When the magnet 17 rotates to the bottom side of the screw rod 16 and is vertically aligned with the Hall sensor 13, the Hall sensor 13 can transmit data to the corresponding controller. The corresponding controller can detect the number of rotations of the screw rod 16, and further detect the displacement of the fixed frame 11 and the metal material, thereby detecting the cutting position of the metal material. When the cutting position of the metal material reaches the specified position, the corresponding controller can automatically control the servo motor 15 to stop working, thereby automatically controlling the cutting position of the metal material.
