Action principle, purpose and scope of use of the press

1. The closed single-point press uses the crankshaft connecting rod mechanism as the working mechanism. The working link of the crankshaft connecting rod mechanism is a rigid structure, and the slider has a strong motion orbit. Therefore, for the set size of the press mechanism, the number of strokes per minute and the movement curve of the slider are fixed.

2. The closed single-point press is a general-purpose press, and its main uses are cutting, blanking, punching, bending, shallow bending, shallow stretching and occlusion. The slider can be used for single stroke or continuous stroke.

3. The feeding mechanism of the press must be installed in the vertical direction of the working table, and then perform a single or continuous stroke.

4. On this press, when the material strength of the blanking material is 50 kg/mm2, the blanking area should not exceed 2300 square mm.

5. No matter when working in a single or continuous stroke, if the thickness of the sheet is 8 mm, the maximum circumference of the blanking diameter is 250 mm, and the maximum diameter is 100 mm.

6. The allowable force of the slider of this press is calculated according to the strength of the crankshaft and the large gear. During stamping work, the given data should be given with reference to the pressure graph, and the strength range of the pressure graph should not be exceeded.
