[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1.

[0021] In addition, when the straightening push block contacts the straightening protrusion, the rectangular straightening plate moves forward under the action of the straightening push block and the straightening protrusion. When the straightening push block separates from the straightening protrusion, the rectangular straightening plate automatically resets backward under the action of two reset springs B. Under the action of friction, the rectangular straightening plate can drive the precision forging raw material to rotate when moving forward or backward. The precision forging raw material can be automatically straightened when rotating, so that the precision forging has higher precision after forming.

[0022] 2. The present invention plays a role in positioning the raw materials of precision forgings, making the precision forgings more consistent after forming. When the raw materials of precision forgings are bent, the two ends of the raw materials of precision forgings can push the two positioning plates to move outward, without affecting the normal forming of the raw materials of precision forgings while achieving the positioning effect;

[0023] In addition, when the precision forging raw material is bent, the two circular movable rods automatically separate from the two receiving grooves. When the two circular movable rods separate from the two receiving grooves, the two circular movable rods can push the rectangular straightening plate upward, so that a slight gap is generated between the bottom of the rectangular straightening plate and the precision forging raw material, which does not affect the normal forming of the precision forging raw material while achieving the straightening effect.

[0024] 3. The present invention facilitates the operator to control the motor and the two electric cylinders. When the control button A is pressed, the motor rotates forward. When the control button A is pressed again, the motor reverses and resets. When the control button B is pressed, the output shafts of the two electric cylinders extend. When the control button B is pressed again, the output shafts of the two electric cylinders retract and reset.

[0025] In addition, when the staff presses control button A or control button B, the staff needs to pull out the rectangular storage plate through the U-shaped handle with one hand and press control button A or control button B with the other hand, ensuring that the staff's hands are in a safe area when pressing control button A or control button B, avoiding accidental injury to the staff by the equipment.
