[0002] Fasteners are also called standard parts in the market. They are mechanical components that can fix or bond two or more components together in a mechanical manner. They are characterized by a wide variety of product specifications, different performance uses, and a very high degree of standardization, serialization, and generalization. Fasteners are the most widely used mechanical basic parts and have a large demand. In existing fastener bar cutting equipment, when cutting a bar, no fixing mechanism is provided at the bar cutting mechanism, and only the bar pushing mechanism is used to limit the bar, resulting in the bar offset during cutting, so that the cutting port is misaligned with the original position, reducing the cutting quality of the bar. For this reason, we have proposed a bar cutting device for processing screw fasteners. Content of the Utility Model

The connecting plate 4 is movably connected to the base 3, so that the connecting plate 4 can rotate around the base 3 through the pin shaft. One side of the connecting plate 4 away from the base 3 is fixedly installed with a motor 5. The rotating shaft of the motor 5 penetrates the connecting plate 4 and is fixedly connected to a cutter 6. When the motor 5 is working, the motor 5 can drive the cutter 6 to rotate, so as to achieve the purpose of cutting the bar through the rotating cutter 6. The upper end of the support frame 2 is movably connected to the connecting plate 4 through a first hydraulic cylinder 7. Both ends of the first hydraulic cylinder 7 are movably connected to the support frame 2 and the connecting plate 4 through pin shafts respectively. When the first hydraulic cylinder 7 is working, the first hydraulic cylinder 7 can push the connecting plate 4 to rotate around the base 3. One side of the workbench 1 close to the support frame 2 is provided with a support plate 8. One side of the support plate 8 away from the support frame 2 is provided with a second hydraulic cylinder 9. The stroke end of the second hydraulic cylinder 9 is fixedly connected to a pusher plate 10. When the second hydraulic cylinder 9 is working, the second hydraulic cylinder 9 pushes the pusher plate 10 to move in the horizontal direction. Through the push of the pusher plate 10, the bar to be cut can move in the horizontal direction on the support plate 8. Above the workbench 1, on the side away from the second hydraulic cylinder 9, there are two symmetric third hydraulic cylinders 11. The stroke end of the third hydraulic cylinder 11 is fixedly connected to a movable clamping block 12. On the workbench 1, there is a fixed clamping block 13 matching the movable clamping block 12. On the side where the movable clamping block 12 and the fixed clamping block 13 approach each other, there is a fixed groove 14. When the third hydraulic cylinder 11 is working, the third hydraulic cylinder 11 can push the movable clamping block 12 to move in the horizontal direction. When the movable clamping block 12 and the fixed clamping block 13 approach each other, through the mutual cooperation between the movable clamping block 12 and the fixed clamping block 13, the purpose of positioning the bar can be achieved.
[0024] A slider 15 is provided below the movable clamping block 12, and a slide rail 16 matching the slider 15 is provided on the workbench 1. The slider 15 can slide on the slide rail 16. Through the mutual cooperation between the slider 15 and the slide rail 16, the moving stability of the movable clamping block 12 is effectively improved.
[0025] A protective cover 17 is provided outside the cutting tool 6. The protective cover 17 can protect the cutting tool 6 and reduce the probability of the cutting tool 6 causing injury to the staff.
