Description

Technical Field

[0001] The utility model relates to the technical field of fuel tank stamping processing, in particular to a fuel tank stamping production die. Background Art

[0002] As an important component of an excavator, the existing fuel tank is usually welded from scattered parts and plates. The stamping die applies external force to the plate to cause it to undergo plastic deformation or separation, thereby obtaining a fuel tank plate of the desired shape and size.

[0003] The patent with publication number CN220295652U and the name of a fuel tank stamping production mold discloses a fuel tank stamping production mold. Through the use of a lifting mechanism, the height of the mold mechanism can be adjusted accordingly to ensure that the raw materials can be easily placed inside the mold mechanism. In addition, the structure is simple and easy to use. The same power source makes the use of both ends consistent and more stable. Through the use of a snap-on replacement mechanism, the mold on the height adjustment plate can be more conveniently replaced, ensuring that molds of different sizes and positions can be used, and improving flexibility and integrity during use. This patent lacks a component for ejecting materials, and the fuel tank formed in the deeper lower mold is not easy to remove, resulting in inconvenience for staff to retrieve materials.
