Description

Technical Field

[0001] The utility model belongs to the technical field of presses, and in particular relates to an automatic production line for presses. Background Art

[0002] The pressure stamping and bending machine is a commonly used metal sheet processing equipment, which can perform stamping, bending, stretching and other processing operations on metal sheets. In the manufacturing industry, metal sheet processing is an indispensable part, so the application of pressure stamping and bending machines is also very extensive. However, there are some problems with traditional pressure stamping and bending machines. The most important problem is that after the sheet is cut, it needs to be placed on the press manually for stamping and forming. When the sheet is placed manually, it is difficult to ensure the accuracy of the sheet placement due to the instability of human hand movements and visual judgment. This will cause large dimensional deviations in stamping and forming, affecting product quality. During the operation, workers need to directly contact the stamping die. Once improperly operated, it will cause serious personal injury. Utility Model Content
