Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to an automatic discharging device for sheet metal processing. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts.

[0003] The patent with publication number CN 212217321 U discloses an automatic discharging device for sheet metal processing, which includes a support table, a support frame is fixedly connected to the upper surface of the support table, and the lower ends of the left and right side walls of the support frame are provided with connecting holes. The device controls the rotation of the motor through a controller, thereby causing the hollow rotating barrel to drive the shifting frame to rotate, so that the interval time between the shifting frame and the cutting knife contacting the processing plate is different, thereby achieving the purpose of adjusting the cutting knife to cut the processing plate of different lengths, and solving the problem that the existing automatic discharging device for sheet metal processing cannot cut sheet metal plates of different lengths according to the needs of the staff, but the device has the problem that the sheet metal plates that need to be cut are cut into pieces. The sheet metal plate is placed on the carrier frame, and then the hollow rotating barrel is driven by a motor to cooperate with the toggle frame and the cutting knife to move and cut the sheet. However, the distance between the toggle frame responsible for toggling and sending out the sheet and the support table in this device is fixed. This results in that when the sheet passes through the connecting hole into the support frame, if the sheet is thin, it cannot be toggled by the toggle frame. If the sheet is thick, the sheet cannot be placed between the support table and the toggle frame for feeding and cutting, which affects the processing of the sheet metal parts. For this reason, an automatic discharge device for sheet metal processing is proposed to solve the problem that the existing sheet metal discharge device is difficult to transport and discharge according to the thickness of the sheet metal.
