It can automatically process holes of different shapes with different sizes and hole pitches as required. During the processing of the numerical control punch, a feeding device is required to feed the metal sheet.

[0003] A Chinese patent with the publication number CN215902598U discloses an automatic feeding device for numerical control punch sheets, including a transport plate. A plurality of grooves are formed on the top surface of the transport plate, and a plurality of balls are arranged in each of the grooves. A deviation prevention component is arranged outside the transport plate; mounting blocks are connected to the front end face and the rear end face of the transport plate respectively. Chutes are formed in both of the mounting blocks, the chutes are arranged vertically, screws are arranged in both of the chutes, and the bottoms of the two screws are rotatably matched with the chutes. The beneficial effects are as follows: By arranging the deviation prevention component, the device can avoid the deviation of the sheet body during the feeding process, resulting in incorrect stamping positions; and arranging grooves and balls on the top surface of the transport plate can make the sheet body better transported and reduce its friction.

[0004] During the feeding process of the existing numerical control punch feeding device for the sheet, the placement position of the sheet is inaccurate and prone to deviation, resulting in poor feeding accuracy; therefore, a numerical control punch feeding device is proposed for the above problems.

During operation, in the process of feeding the plate 5 by the existing feeding device for the numerical control punching machine 26, the placement position of the plate 5 is inaccurate and prone to deviation, resulting in poor feeding accuracy. By placing the plate 5 in the guide cylinder 4, when the first stepping motor 29 operates, it drives the first lead screw 7 to rotate. The first lead screw 7 drives the slider 8 on it to move horizontally. The slider 8 drives the pushing block 9 to move horizontally. The pushing block 9 pushes the lowest plate 5 in the guide cylinder 4 to move downward along the ramp of the feeding table 3.
