Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] refer to Figures 1-3The friction feeding mechanism for stamping machine processing shown includes a feeding base 1, a positioning bracket 2 on the feeding base 1, and a friction feeding assembly on the positioning bracket 2. The friction feeding assembly includes a side seat plate 301, a slide table 302, a spring 303, a first roller 304, and a second roller 305. The side seat plate 301 is slidably connected to the feeding base 1 and is fixedly connected to the feeding base 1 by locking screws. The slide table 302 is slidably connected to the side seat plate 301. The first roller 304 and the second roller 305 are rotatably connected to the slide table 302 and the positioning bracket 2, respectively. A lower positioning assembly 4 is provided on the upper part of each feeding base 1.

[0020] A stepper motor 5 is fixedly connected to the positioning bracket 2. The rotation of the stepper motor 5 drives the second roller 305 to rotate, feeding the workpiece under the action of friction. The first roller 304 and the second roller 305 are arranged in parallel. Both the first roller 304 and the second roller 305 are made of rubber, which can improve the friction between them and the workpiece, and avoid damage to the surface of the workpiece.

[0021] The feeding base 1 is provided with a guide groove 101. The side seat plate 301 is slidably connected to the guide groove 101. The guide groove 101 can guide the position adjustment of the side seat plate 301. Adjusting the position of the slide table 302 can adapt to the feeding and positioning of workpieces of different widths. On the other hand, it can adjust the pressure applied to the workpiece by the first roller 304 after the workpiece is placed. The slide table 302 can guide the sliding of the side seat plate 301. The spring 303 is located between the slide table 302 and the side seat plate 301.

[0022] The lower positioning assembly 4 includes a screw 401, a limiting rod 402, and a lower positioning seat 403. The lower positioning seat 403 has a limiting hole, and the limiting rod 402 is located inside the limiting hole. This ensures that when the screw 401 is rotated, the lower positioning seat 403 can only move up and down along the limiting rod 402 and will not rotate. The limiting rod 402 is slidably connected to the limiting hole. The upper end of the screw 401 is rotatably connected to the lower positioning seat 403. When the screw 401 is rotated, the screw 401 moves up and down relative to the feeding base 1, while the screw 401 only rotates relative to the lower positioning seat 403.

[0023] The end of the feeding base 1 is provided with a feeding alignment component 6. When feeding the workpiece, one end of the workpiece is aligned to ensure the consistency of the feeding process. The feeding alignment component 6 includes a rotating device 601 and a rotating baffle 602. The rotating device 601 can drive the rotating baffle 602 to rotate.

[0024] The working principle of this utility model is as follows: Before feeding, the distance between the first roller 304 and the second roller 305 can be adjusted according to the width of the workpiece (plate or pipe). The position of the slide table 302 is adjusted by sliding the side seat plate 301, and then the side seat plate 301 is fixed by locking screws to complete the adjustment. After that, the distance between the lower positioning seat 403 and the positioning bracket 2 is adjusted according to the thickness of the workpiece. By rotating the screw 401, the lower positioning seat 403 is raised and lowered along the limit rod 402 to adjust the height under the drive of the screw 401 relative to the feeding base 1.

[0025] After the positions of the first roller 304 and the lower positioning seat 403 are adjusted, the workpiece is pushed along the first roller 304, the second roller 305, the positioning bracket 2 and the lower positioning seat 403 to the rotating baffle 602. After the workpiece is placed, it will push the first roller 304 to make the slide table 302 slide away from the positioning bracket 2. The spring 303 is compressed, which makes the first roller 304 apply pressure to the workpiece, increasing the friction between the workpiece and the second roller 305, ensuring that the workpiece does not slip when friction feeding is performed. Subsequently, when loading, the second roller 305 is driven to rotate by the stepper motor 5 to feed the workpiece.

[0026] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
