Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal bending and punching devices, and specifically relates to a sheet metal bending and punching device. Background Technique

[0002] A sheet metal bending and punching device is a device used for sheet metal processing, mainly including two functions of a bending machine and a punching machine. This device is usually used for bending and punching metal sheets to manufacture various metal parts with different shapes and sizes.

[0003] Currently, some sheet metal bending and punching devices usually punch and bend metal sheets to turn them into required parts. The metal sheets are usually wound up. During processing, the metal sheets are released by a unwinding roller and conveyed to a processing table for punching and bending. However, when the metal sheets are released from the unwinding roller, their surfaces sometimes become curved. If they are directly punched and bent without treatment, it will cause errors in the processed dimensions of the parts. At the same time, when the punching head is punching, waste materials are easily stuck in the punching head, resulting in the punching head being unable to be used normally and affecting the product quality.

[0004] Therefore, we make improvements and propose a sheet metal bending and punching device. Content of the Utility Model

The bending groove 202 facilitates the bending head 603 to bend the metal sheet, and the cutting groove 203 facilitates the cutting knife 605 to cut the metal sheet.

[0033] Among them, a limiting block 10 is installed on one side of the upper end surface of the processing table 2 far from the bending and punching mechanism 6. The metal sheet passes through the limiting block 10, and the limiting block 10 plays a role in limiting the metal sheet.

[0034] Among them, a collection groove 9 is provided on the upper end surface of the workbench 1 below the blanking groove 201, and a collection drawer 901 is installed in the collection groove 9, and the collection drawer 901 can collect waste materials.

[0035] Working principle: First, start the first motor 802, and the first motor 802 drives the unwinding roller 801 to rotate. The unwinding roller 801 conveys the metal sheet to the processing table 2 through rotation. The metal sheet passes through the limiting block 10, and the limiting block 10 plays a limiting role on the metal sheet. When the surface of the metal sheet is bent, start the first cylinder 502, and the first cylinder 502 pushes the flattening roller 504 downward through the mounting block 503, so that the flattening roller 504 presses on the surface of the metal sheet. Then start the second motor 303, and the second motor 303 drives the lead screw 302 to rotate. Since the lead screw 302 is threadedly connected to the first slider 301, when the lead screw 302 rotates, it drives the first slider 301 to move to one side. The first slider 301 drives the cross bar 501 to move to one side through the mounting plate 5. The cross bar 501 drives the flattening roller 504 to move to one side through the first cylinder 502. When the flattening roller 504 moves to one side, it can flatten the metal sheet, thereby avoiding the deviation of the processed part size caused by the bending of the metal sheet. When the mounting plate 5 moves, it drives the second slider 401 to move on the limiting rod 402. When the metal sheet moves below the bending and punching mechanism 6, start the second cylinder 601, and the second cylinder 601 drives the support seat 602 to move downward. The support seat 602 simultaneously drives the bending head 603, the punching head 604 and the cutting knife 605 to move downward. The bending head 603 bends the metal sheet, the punching head 604 punches the metal sheet, and the cutting knife 605 cuts the metal sheet. After the punching head 604 punches the hole in the metal sheet, under the action of the compression spring 702, the compression spring 702 pushes the ejecting block 703 downward, so that the waste material in the punching head 604 can be ejected, thereby avoiding the waste material being stuck in the punching head 604 and causing the punching head 604 to be unable to be used normally, affecting the product quality. The ejected waste material enters the collection drawer 901 in the collection groove 9 through the blanking groove 201 for collection.
