[CN 202011606232.3] Active material returning device of press machine
[CN 202011606232.3] Title of an Active Material Withdrawal Device for a Press: Application Number of an Active Material Withdrawal Device for a Press: CN 202011606232.3 Applicant: Jiangsu Yangli Casting and Forging Co., Ltd. Application Date: 2020-12-30 Patent Type: Application of the Invention The present invention relates to an active material withdrawal device for a press in the technical field of presses, including a sliding block for fixing a stamping die under the sliding block, and a material withdrawal groove for accommodating a material withdrawal plate, the material return plate is located in the material return groove, and is characterized in that both sides of the material return plate extend horizontally out of the material return groove and are respectively connected with material return cylinders, and the cylinder body of the material return cylinder is fixed with the slider, The piston rod of the material return cylinder extends vertically and is fixed with the material return plate, the material return action of the material return plate is driven by the piston rod, and the material return cylinder is driven by the oil and gas control pipeline. In the active material return device of the press of the present invention, the material return plate is directly driven and connected with the material return cylinder. During the return process after sliding stamping, the material return cylinder can be driven at any time through the oil and gas control pipeline to realize the material return action, and the material return stroke length and the material return execution speed of the material return plate driven by the material return cylinder can be controlled, which is suitable for the material return requirements of different stamping dies and stamping depths, and has strong applicability.
