[0023] A feeding device for bar cutting provided by the utility model is now described.
[0024] like Figures 1 to 3As shown, one embodiment of the utility model provides a feeding device for bar cutting, including a slide 2 slidably arranged on a body 1, and the slide 2 has at least four groups; a cavity 11 with openings on both sides is opened inside the body 1 along the sliding direction of the slide 2; the slide 2 includes a moving table 21 and a supporting table 22, the moving table 21 is slidably arranged in the cavity 11, the supporting table 22 is located on the body 1 and connected to the moving table 21, and the supporting table 22 is used to support the bar; a transmission assembly 3 is arranged between the moving table 21 and the body 1, and each moving table 21 is provided with a power piece 4, and the power piece 4 drives the corresponding moving table 21 to slide through the transmission assembly 3.
[0025] When cutting the bar, the bar is first sent into the machine body 1, and the two outermost slides 2 support the two ends of the bar, and the two inner slides 2 support the two sides of the cutting surface of the bar, thereby improving the stability and safety during the bar cutting; after the bar cutting is completed, both ends of the two sections of the bar are supported by the slides 2, and the two slides 2 under the cut bar can be directly slid outward for sending.
[0026] Compared with the prior art, the feeding device for bar cutting provided in the present embodiment supports and moves the bar through multiple groups of slides 2. The setting of the cavity 11 can improve the sliding stability of the slide 2. The setting of the power part 4 can realize the independent sliding of each slide 2, so that the ends of the two cut bar pieces are supported by the slide 2 and driven to slide stably outward, thereby improving the loading safety before bar cutting and the unloading safety after cutting.
[0027] like Figures 2 to 3 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0028] A slide rail 111 is disposed in the cavity 11 , and a slider 211 is disposed on the moving platform 21 . The slider 211 is slidably connected to the slide rail 111 .
[0029] When the power member 4 drives the moving platform 21 to slide through the transmission assembly 3 , the sliding block 211 slides on the sliding rail 111 , thereby improving the sliding stability of the moving platform 21 .
[0030] like Figures 2 to 3 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0031] The transmission assembly 3 includes a ball screw 31, multiple rotating nuts 32, multiple rotating support members 33 and multiple groups of transmission members 34. The ball screw 31 is fixedly arranged in the cavity 11, and the rotating nut 32 is threadedly connected to the ball screw 31; the rotating support member 33 is connected between the rotating nut 32 and the corresponding moving platform 21, and the power member 4 drives the corresponding rotating nut 32 to rotate through the transmission member 34. The rotating support member 33 is used to drive the moving platform 21 to slide when the rotating nut 32 rotates.
[0032] When the power member 4 drives the rotating nut 32 to rotate through the transmission machine, the rotating nut 32 moves on the ball screw 31. At the same time, the rotating nut 32 drives the moving platform 21 to slide along the length direction of the ball screw 31 through the rotating support member 33, thereby improving the efficiency of the independent sliding of the moving platform 21.
[0033] like Figure 3 to Figure 4 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0034] The rotating support member 33 is a bearing and is coaxially arranged with the rotating nut 32 . The inner ring of the rotating support member 33 is fixed to the rotating nut 32 , and the outer ring of the rotating support member 33 is fixed to the moving platform 21 .
[0035] The bearing arrangement of the rotating support 33 can reduce the friction between the rotation of the rotating nut 32 and the moving platform 21 on the one hand, and can stably realize the rotation of the rotating nut 32 to drive the moving platform 21 to translate on the other hand.
[0036] like Figure 3 to Figure 4 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0037] A first limiting ring plate 35 is coaxially fixed between the movable platform 21 and the outer ring of the rotating support member 33, and a second limiting ring plate 36 is coaxially fixed between the rotating nut 32 and the inner ring of the rotating support member 33; a plurality of limiting rings 351 are arranged on the inner circumference of the first limiting ring plate 35, and a plurality of limiting ring grooves 361 are opened on the outer circumference of the second limiting ring plate 36 for the corresponding limiting rings 351 to rotate inside.
[0038] When the rotating nut 32 rotates, it drives the second limiting ring plate 36 to rotate. At this time, the limiting ring 351 rotates relatively in the limiting ring groove 361, so that the second limiting ring plate 36 can apply a horizontal force to the first limiting ring plate 35, thereby reducing the workload of the rotating support 33 and improving the transmission stability of the rotating nut 32 driving the movable platform 21 to move horizontally.
[0039] like Figures 2 to 3 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0040] The transmission member 34 includes a first transmission wheel 341, a second transmission wheel 342 and a transmission belt 343. The first transmission wheel 341 is connected to the power member 4, the second transmission wheel 342 is coaxially fixed on the rotating nut 32, and the transmission belt 343 is sleeved between the first transmission wheel 341 and the second transmission wheel 342. The radius of the first transmission wheel 341 is smaller than the radius of the second transmission wheel 342.
[0041] Specifically, in this embodiment, the first transmission wheel 341 and the second transmission wheel 342 are both pulleys with teeth on the outer ring, and the inner ring of the transmission belt 343 has teeth meshing with the outer rings of the first transmission wheel 341 and the second transmission wheel 342. In this embodiment, the power member 4 is a motor, and the output shaft of the power member 4 is coaxially fixed with the first transmission wheel 341.
[0042] like Figure 2 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0043] The cavity 11 has downwardly opened bent portions 112 on both sides, and the shape of the moving platform 21 matches the bent portions 112 .

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
