Detailed ways

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

An automatic loading device for a punch press. The loading device includes a base 1, a lifting loading frame 2 installed on the base 1, a feeding component and a feeding component installed on the loading frame 2.

Here, the base 1 is provided with a chute 15 extending in the vertical direction. As shown in Figures 1 and 2, the loading device also includes a threaded hole provided on the loading frame 2 and a through hole extending along its own axial direction. Behind the chute 15 are bolts (not shown in the figure) that are threaded and locked with the threaded holes on the loading frame 2 . Through this arrangement, the height of the loading frame 2 can be adjusted according to actual processing needs. When the loading frame 2 is adjusted to the required height, the loading frame 2 and the base 1 are locked with bolts.

In this example, the feeding assembly includes several feeding brackets 3 installed on the feeding frame 2 and extending along the feeding direction. See Figures 1 and 3. The upper end of the feeding bracket 3 is equipped with a support for supporting The universal wheels 4 on the lower surface of the material are shown in Figures 1 and 3. The universal wheels 4 are distributed on the feeding bracket 3 at intervals along the feeding direction. By arranging the universal wheel 4 on the feeding bracket 3, the friction between the material and the feeding bracket 3 during the feeding process is greatly reduced, ensuring the stability of the material during the feeding process.

In this example, the feeding assembly also includes a pushing mechanism and a positioning mechanism installed on the feeding frame 2 . The push mechanism includes a push plate 5 installed between two adjacent feed brackets 3 that can slide along the feeding direction. A rubber pad 6 is also installed on the side of the push plate 5 that is in contact with the material. See As shown in Figures 1 and 3, the rubber backing plate 6 is provided to prevent hard contact between the push plate 5 and the material, causing wear and tear on the material. The positioning mechanism includes a fixed plate 8 and a positioning plate 7 which are relatively installed on both sides of the feeding frame 2. As shown in Figures 1 and 3, the positioning plate 7 can be close to or along the direction perpendicular to the length extension of the feeding frame 3. Stay away from the fixed plate 8. By setting up a positioning mechanism, sorting and aligning the plates placed on the feeding bracket 3 is beneficial to subsequent feeding operations, and by setting up a pushing mechanism, the materials can be pushed to the side of the feeding component without manual operation and with a high degree of automation.
