[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] Example

[0018] like Figures 1 to 2As shown, a metal support leg fixed-length cutting device includes a cutter 11, a motor 5 fixed on a crossbeam 4, and a workbench 2 fixed on a base 1. The two ends of the crossbeam 4 are fixed to the base 1 by two uprights 3 respectively. A limit frame 13 and a shaft frame 15 are fixed on the workbench 2. A feeding wheel 16 is rotatably connected to the shaft frame 15. A worm 6, a worm wheel 7, a worm wheel 8, and a gear 18 are rotatably connected to the crossbeam 4 by a fixed axis. The worm 6 is driven by the motor 5. The worm 6 is also meshed with the worm wheel 7 and the worm wheel 8. The gear 18 is driven by the feeding wheel 16 through a pulley assembly 17. The cutter 11 is fixed to the bottom of the cutter holder 10. The cutter holder 10 is hinged to the disk surfaces of the worm wheel 7 and the worm wheel 8 at positions away from the center by two connecting rods 9 respectively. A notched gear ring 20 is coaxially fixed to the disk surface of the worm wheel 7 and meshes with the gear 18.

[0019] In this embodiment, the first worm gear 7 and the second worm gear 8 have the same structure and are symmetrically arranged on both sides of the worm 6, and the two connecting rods 9 are symmetrically arranged.

[0020] In this embodiment, a bracket 12 is fixed to the side of the workbench 2, and the cutting position of the cutter 11 is located between the bracket 12 and the limiting frame 13.

[0021] In this embodiment, a guide component is provided on the workbench 2, and the guide component is located between the limiting frame 13 and the shaft frame 15. The workpiece passes through the lower end of the feeding wheel 16, the guide component and the limiting frame 13 in sequence.

[0022] In this embodiment, the guiding assembly includes two plate frames 24 symmetrically fixed on the upper surface of the workbench 2. Two guide clamps 14 are arranged between the two plate frames 24. Guide wheels 23 are rotatably connected to the opposite side of the two guide clamps 14. Screws 25 are threaded through and connected to the plate frames 24, and the screws 25 are rotatably connected to the corresponding guide clamps 14.

[0023] In this embodiment, a belt conveyor 21 for outputting cut workpieces is provided on the base 1, and a baffle 22 is fixed on the belt of the belt conveyor 21. A stop block 19 is fixed on the corresponding upright 3 on the cutting side. The stop block 19 is located above the belt conveyor 21. The stop block 19 is L-shaped to prevent the left end from tilting up when the cutter 11 cuts. The baffle 22 serves to prevent the falling workpiece from slipping.

[0024] The principle and advantages of this utility model: This metal leg fixed-length cutting device allows one end of the long strip workpiece to be cut to pass sequentially through the lower end of the feeding wheel 16, between the two guide clamps 14, and the limiting frame 13. Rotating the two screws 25 causes them to push the guide clamps 14 to fit and limit the workpiece from both sides. The guide wheel 23 facilitates the movement of the workpiece, thus ensuring directional stability during workpiece feeding. The motor 5 and belt conveyor 21 are started. The motor 5 drives the worm gear 7 and worm gear 8 to rotate at the same speed but in opposite directions via the worm gear 6. This causes the worm gear 7 and worm gear 8 to drive the cutter holder 10 and its lower cutter 11 to reciprocate up and down via the two connecting rods 9. Simultaneously, the rotation of the worm gear 7 drives the gear ring 20 to move synchronously, causing the gear ring 20 to drive... Gear 18 rotates, causing it to drive feed wheel 16 to rotate via pulley assembly 17. Feed wheel 16 then moves the workpiece toward stop 19. When cutter 11 moves down and is about to contact the workpiece, gear ring 20 just separates from gear 18, and the end of the workpiece abuts against stop 19. Cutter 11 continues to move down to cut the workpiece, and the cut workpiece falls onto belt conveyor 21 for output. When cutter 11 moves up above the workpiece, gear ring 20 meshes with gear 18, causing gear 18 to drive feed wheel 16 to transport the workpiece via pulley assembly 17. Since the length of gear ring 20 is fixed, the transport length of the workpiece is fixed, and automatic continuous fixed-length cutting of workpieces is achieved, greatly improving work efficiency.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
