Description

Technical Field

[0001] The utility model belongs to the technical field of debris cleaning, in particular to a debris cleaning device for a bending machine. Background Art

[0002] A press brake is an important piece of metal processing equipment. It is usually composed of a machine body, a workbench, a slider, a mold, a hydraulic system and other parts. The machine body has a stable structure, providing solid support for the entire equipment. The workbench is used to place the metal sheets to be processed. The slider is driven by the hydraulic system and moves up and down along the guide rail to apply pressure to the sheet. The mold is installed on the slider and the workbench and is replaced according to different needs to determine the bending shape and angle of the sheet. During the operation of the press brake, a debris cleaning device is generally used to clean the debris generated during bending.

[0003] The debris cleaning device for a bending machine mainly consists of a collection trough, a dust suction port, a dust suction pipe, a dust suction fan, and a dust collection box. The collection trough is located below the bending machine workbench and is used to receive fallen debris. The dust suction port is located above the collection trough and is connected to the dust suction fan through the dust suction pipe. The dust suction fan generates a strong suction force and draws the debris into the pipe. The dust collection box is used to store the sucked-in debris. The principle is that when the bending machine is working, the generated debris falls into the collection trough, the dust suction fan starts, and negative pressure is formed at the dust suction port, which draws the debris into the dust collection box through the dust suction pipe, thereby effectively cleaning the debris generated during the bending machine operation and keeping the working environment clean.

[0004] When the existing debris cleaning device of the bending machine collects debris, debris will accumulate, which will cause the debris to overflow outside the device when pushing and collecting materials, resulting in poor debris cleaning effect. In addition, when the existing debris cleaning device of the bending machine performs a dust suction operation, debris will clog the dust suction port, which will cause the device to not operate normally and reduce the service life of the device, resulting in cleaning failure. Therefore, a debris cleaning device for a bending machine is proposed to address the above problems. Utility Model Content
