[0016] Compared with the prior art, the present application has the following advantages:

[0017] 1) When the large I-beam forming and machining press is used, the servo motor is controlled to reverse, the second rotating shaft drives the second synchronous wheel to rotate through the first synchronous wheel and the synchronous belt, under the action of the clamping block and the clamping slot, the second synchronous wheel drives the third rotating shaft and the dial to rotate, the dial drives the gear wheel to rotate through the gear tooth and the gear slot, until the gear tooth is separated from the gear slot, at the same time, the dial is combined with the arc-shaped slot on the gear wheel, the gear wheel is limited by the dial and the arc-shaped slot and remains stationary, until the gear tooth is combined with the next gear slot, the intermittent movement of the rotating frame is realized, so that the pressure head is automatically switched, and the press is suitable for batch continuous production of workpieces of various specifications.

[0018] 2) When this large I-beam forming press is in use, the first slide rod on the rotating plate slides inside the first annular groove as the rotating frame rotates. The Y-shaped groove consists of a straight groove and two inclined grooves. As the rotating frame rotates, one of the two first slide rods on the rotating plate enters the straight groove through the inclined groove on one side. At this time, the entire rotating plate will rotate 180 degrees around the first slide rod in the straight groove as the rotation axis. Then, the first slide rod inside the straight groove will return to the first annular groove through the inclined groove on the other side. Under the action of the Y-shaped groove, the pressure head at the highest position faces the worktable, and the pressure heads at other positions face outward, which is convenient for the operator to disassemble and replace the pressure heads.

[0019] 3) When using this large I-beam forming press, the clamping block and the clamping slot are used to control the unidirectional movement of the third rotating shaft. Under the elastic force of the second spring, the clamping block can automatically engage with the corresponding clamping slot. When the second synchronous wheel outside the third rotating shaft rotates forward, the clamping slot will squeeze the clamping block and compress the second spring at the same time. At this time, the clamping block and the clamping slot only slide against each other, and the second synchronous wheel will not drive the third rotating shaft to rotate. When the second synchronous wheel rotates in reverse, because the clamping block engages with the clamping slot, the second synchronous wheel can drive the third rotating shaft to rotate. This makes the pressing down and switching of the press head controlled by the same servo motor but independently separate, without interfering with each other. Attached Figure Description
