The fixing piece is used for fixing the plate spring, is of a U-shaped structure, and is generally formed by punching through a special die and produced in batches.
In the prior art, for example, a chinese utility model patent with publication number CN209049978U discloses a forming device for a U-shaped plate of an axle air suspension bracket, which comprises a female die and a male die for stamping the U-shaped plate and a cylinder body for removing a U-shaped plate product formed by stamping from the female die; the male die is fixedly connected with a punch of the stamping equipment; the female die is connected with the base; the die comprises a first die half and a second die half, a U-shaped groove corresponding to the U-shaped plate is formed in the middle of the die, a positioning groove used for positioning a sample plate is formed in the outer side of the U-shaped groove, an ejection hole communicated with the lower portion of the base is formed in the middle of the U-shaped groove, and a piston rod of the ejection cylinder extends out of the ejection hole into the U-shaped groove. After the female die is matched with the male die to punch the sample plate into a U shape, the piston rod extends out of the ejection hole to eject the product, and then an operator picks up the product and puts the product into the material frame.
The above prior art solutions have the following drawbacks: the forming die is only one group, the working efficiency is low, and the requirement of mass production cannot be met.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims at providing a leaf spring mounting stamping forming frock to reach and improve work efficiency, satisfy the effect of mass production demand.
The above object of the present invention can be achieved by the following technical solutions:
