DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0021] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] like Figures 1-4 As shown, an automatic feeding and bending device for corrugated sheets includes a bending mechanism and a stepping feeding assembly. The stepping feeding assembly consists of two sets capable of conveying the sheet material through the bending mechanism. Each set of stepping feeding assemblies is equipped with an adsorption assembly and a slot assembly for auxiliary feeding. The stepping feeding assembly includes a lead screw slide 4, a horizontal plate 6, and a short-stroke cylinder 7. The lead screw slide 4 has multiple slides 5, and each slide 5 is fixedly connected to a horizontal plate 6. Each horizontal plate 6 is equipped with a short-stroke cylinder 7. The adsorption assembly includes air pipes 8 and vacuum suction cups 9. There are multiple air pipes 8, each connected to a short-stroke cylinder 7 on each horizontal plate 6. Multiple vacuum suction cups 9 are arranged along the length of the air pipes 8. The slot assembly includes a horizontal support 10 and a tapered strip 11. There are multiple horizontal supports 10, each connected to a short-stroke cylinder 7 on each horizontal plate 6. The tapered strip 11 is fixedly arranged on the top of the horizontal support 10.

[0023] Specifically, the lead screw slide 4 drives the slide 5 to slide and translate synchronously via the lead screw, thereby causing the horizontal plate 6 to follow and translate, so that the adsorption component and the card slot component can support the movement of the plate. At the same time, the short-stroke cylinder 7 adjusts the height of the adsorption component and the card slot component so that they can contact the plate. The horizontal plate 6 spans the top of the slide 5 on the two lead screw slides 4. The extension end of the short-stroke cylinder 7 is upward to adjust the height of the adsorption component and the card slot component. The vacuum suction cup 9 and the conical strip 11 are both facing upward to contact the plate and prevent the plate from falling off when transferring the plate.

[0024] Furthermore, the bending mechanism includes a bending machine body 1, a connecting block 12, a bending cutter head 13, an L-shaped block 14, a positioning cutter head 15, and a forming mold 18. The connecting block 12 is connected to the bending machine body 1, and the bending cutter head 13 is fixedly installed at the bottom of the connecting block 12. The L-shaped block 14 is connected to the back of the connecting block 12 and slides therewith. The positioning cutter head 15 is fixedly connected to the bottom of the L-shaped block 14. The forming mold 18 is located below the bending cutter head 13 and the positioning cutter head 15, and the top of the forming mold 18 is provided with a bending cavity 19 and a positioning cavity 20 that are respectively adapted to the bending cutter head 13 and the positioning cutter head 15.

[0025] Specifically, the bending machine body 1 can drive the bending cutter head 13 and the positioning cutter head 15 to descend, so as to apply pressure to the sheet metal. After the bending cutter head 13 applies pressure, it bends the sheet metal into the bending cavity 19 to form it. At the same time, the positioning cutter head 15 can be inserted into the groove after bending to position the corrugated sheet.

[0026] Furthermore, a limiting block 16 is fixed to the back of the connecting block 12, and the limiting block 16 has a sliding groove, in which a slide rail 17 is fixedly installed, and one end of the L-shaped block 14 slides in cooperation with the slide rail 17.

[0027] Specifically, when the bending cutter head 13 rises, the L-shaped block 14 slides down on the slide rail 17. After the bending cutter head 13 falls, the positioning cutter head 15 is first inserted into the groove of the corrugated plate and can rise to avoid affecting the descent of the bending cutter head 13.

[0028] Furthermore, it also includes two sets of support components, which support the stepping feeding components one by one; the support components include a base 2, a side plate 3, and ribs 21. The side plate 3 is fixedly installed on the top of the base 2. There are multiple ribs 21, and the ribs 21 are located between the side plates 3. At the same time, the two ends of the ribs 21 are fixedly connected to the side plates 3. The vacuum suction cup 9 and the tapered strip 11 are both located between two adjacent ribs 21.

[0029] Specifically, the vacuum suction cup 9 and the tapered strip 11 are positioned between 21 so that the sheet material can be placed on top of 21 while avoiding feeding activities of the vacuum suction cup 9 and the tapered strip 11.

[0030] Furthermore, each set of step feeding components has two lead screw slides 4, which are arranged side by side for stable feeding. Each horizontal plate 6 is perpendicular to the lead screw slide 4 and is fixedly connected to the slide 5 in the same direction.

[0031] Furthermore, the connecting block 12, the bending cutter head 13, the L-shaped block 14, and the positioning cutter head 15 are all integrally formed structures to ensure structural stability.

[0032] In the above structure, the sheet material to be bent is placed on the side plate 3, and the slide table 5 is driven to move synchronously by the screw slide table 4. At the same time, the height of the vacuum suction cup 9 is adjusted by the short-stroke cylinder 7 so that the vacuum suction cup 9 can pick up the sheet material. Another set of screw slide tables 4 drives the slide table 5 to move synchronously back and forth. At the same time, the short-stroke cylinder 7 adjusts the height of the vacuum suction cup 9 so that the tapered strip 11 can match the corrugated plate, thereby cooperating to move the sheet material step by step. The bending machine body 1 controls the bending cutter head 13 and the positioning cutter head 15 to descend synchronously. The positioning cutter head 15 first inserts into the groove of the corrugated plate to prevent one side of the corrugated plate from lifting up during bending. Then the bending cutter head 13 applies pressure to the sheet material to make it form a shape that fits the bending cavity 19, thus completing the bending. Through the feeding and bending coordination, the corrugated plate is automatically bent.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
