Stroke control device of press machine of automobile sheet metal component

Abstract

The invention provides a stroke control device of a press machine of an automobile sheet metal component. The stroke control device comprises a scaleplate, a lower fixing plate, an upper fixing plate, a cursor, a control / output panel, a female die, a male die, the press machine and a signal transmission line. When the press machine drives the male die to move, the cursor slides on the scaleplate under driving of the upper fixing plate, the control / output panel displays the scale where the cursor is located, the extension length of the press machine is regulated through the control / output panel according to the forming condition of the sheet metal component between the male die and the female die, and therefore accurate control over the stroke of the press machine is achieved.

Description

technical field [0001] The invention belongs to a press control device, in particular to a pressure stroke control device for automobile sheet metal parts. Background technique [0002] During the stamping process of automobile sheet metal parts, due to the ductility of the metal itself and the pressure of the press being too large or too small, it is easy to cause the sheet metal parts to be thinned or the die-casting is not in place, resulting in a large number of defective products and increasing the production cost. The main reason for the phenomenon is that the control of the press depends on the experience of the operator, and accurate control cannot be achieved. Contents of the invention [0003] In order to solve the above problems, the present invention provides a device that can accurately control the stroke of the press, even if there is no rich operating experience, the precise control of the press can be completed, and the problem of good products caused by ex...
