[0018] Automatic positioning device for sawing machine unloading, such as Figure 1-3As shown, it includes a moving block 3 arranged above the sawing machine bed 1 and on the same side of the cylinder 2, the moving block 3 is arranged on the front side of the saw blade, and the upper end surface of the sawing machine bed 1 is provided with a guide support device that is adapted to be connected with the moving block 3 and can enable the moving block 3 to move forward and backward along the feeding direction of the long material, the upper end surface of the moving block 3 is formed with a guide groove along its width direction, and the bottom of the transverse guide rail 4 used to position the front end of the long material extending out of the saw blade is adapted to be connected with the guide groove on the upper end surface of the moving block 3, the upper end surface of the sawing machine bed 1 is provided with a transverse control device for pulling the transverse guide rail 4 away from the front end of the long material, and the two ends of the transverse control device are respectively connected to the right end of the transverse guide rail 4 and the lifting shell of the cylinder 2 2-1 is connected, and the rightward movement and reset of the transverse guide rail 4 is realized in the process that the lifting shell 2-1 drives the saw blade to move downward; in the above structure, by arranging the longitudinal guide rail 10 and the moving block 3 connected with the longitudinal guide rail 10 at the upper end of the sawing machine bed 1, the transverse guide rail 4 connected with the moving block 3 is provided with forward and backward adjustment conditions, and the positioning conditions are provided for the part of the front end of the long material extending out of the saw blade. The transverse guide rail 4 has a large positioning range for the long material, and the adjustment is convenient and quick; by utilizing the structural characteristics of the sawing machine itself, the transverse guide rail 4 is pulled apart from the front end of the long material by the transverse movement control device arranged on the upper end surface of the sawing machine bed 1 and then reset, which is convenient for the discharge of the cut material and provides the initial conditions for the next positioning;

[0019] The specific structure of the transverse movement control device is as follows: the transverse movement control device includes a pull rope 5, a lower universal pulley 6 and an upper universal pulley 7. The upper end surface of the sawing machine bed 1 is provided with a support guide rail 8 parallel to the feeding direction of the long material, and a support slider 9 is adapted to be connected to the support guide rail 8. The lower universal pulley 6 is installed on the support slider 9, and the upper universal pulley 7 is installed on the upper end surface of the fixed guide column 2-2 of the oil cylinder 2. One end of the pull rope 5 is connected to the right end of the transverse guide rail 4, and the other end of the pull rope 5 bypasses the lower universal pulley 6 and the upper universal pulley 7 in turn and is connected to the lifting shell 2-1, and during the descent of the lifting shell 2-1, the pull rope 5 pulls the transverse guide rail 4 to move right and reset; in the above structure, the structural characteristics of the sawing machine itself are utilized, and there is no need to specially set up a device for controlling the rightward movement and reset of the transverse guide rail 4. The driving structure of the invention has the front end of the long material pressed against the inner wall of the transverse guide rail 4, so that the transverse guide rail 4 can position the protruding length of the long material. When the lifting shell 2-1 descends, the lifting shell 2-1 pulls the draw rope 5 downward, and under the guidance of the lower universal pulley 6 and the upper universal pulley 7, the draw rope 5 is used to pull the transverse guide rail 4 to move right and reset. After the long material is cut, the lifting shell 2-1 moves up. At this time, the draw rope 5 is in a relaxed state, and the transverse guide rail 4 is manually pushed to the left to position the starting section of the next round of long material. The above process is repeated to complete the automatic positioning and cutting of the long material. The setting of the lower universal pulley 6 and the upper universal pulley 7 provides guiding and supporting conditions for the draw rope 5, and can effectively compensate for the problem that the two ends of the draw rope 5 are not on the same plane, so as to ensure that the draw rope 5 smoothly pulls the transverse guide rail 4 to move right.

[0020] like Figure 1-3 As shown, the specific structure of the guide support device is as follows: the guide support device includes a longitudinal guide rail 10, the guide groove on the bottom surface of the moving block 3 is adaptively connected to the longitudinal guide rail 10, and the upper end surface of the longitudinal guide rail 10 is provided with a scale line 11 for measuring the length of the front end of the long material from the saw blade; in the above structure, the movement of the moving block 3 is adjusted by manual operation; in order to realize the automatic control of the moving distance of the moving block 3, the guide support device can adopt a servo electric cylinder, so that the moving block 3 is fixed to the telescopic end of the servo electric cylinder, and the moving size of the moving block 3 can be automatically controlled, with high movement accuracy, ensuring the quality and accuracy of long material cutting.

[0021] In order to ensure the reliable position of the moving block 3 after it is adjusted into place and facilitate batch cutting, a handwheel bolt 12 is threadedly connected to the upper end face of the moving block 3, and the handwheel bolt 12 is rotated so that its lower end presses against the longitudinal guide rail 10 to achieve the fixation of the adjusted moving block 3 on the longitudinal guide rail 10. When the transverse guide rail 4 is reset, the reliability of the position of the moving block 3 is guaranteed, providing accurate positioning conditions for the next positioning adjustment of the transverse guide rail 4.

[0022] This technical solution has a simple structure, novel design, low cost, and high length positioning accuracy. It solves the problems of high labor intensity, low efficiency, and high labor cost in the traditional manual measurement and cutting method, improves the cutting efficiency and accuracy of long materials, has good cutting consistency, and can be cut in batches.
