Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the present invention during processing.
Fig. 3 is a schematic view of arc steel and bar steel when they are welded.
The device comprises a lower die base 1-1, a lower die main body 1-2, a baffle 1-3, an upper die connecting block 2-1, a middle column 2-2, an upper die lower pressing plate 2-3, an arc-shaped pressing plate 2-4, a guide column 2-5, strip steel A, an arc-shaped strip a and strip steel B.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example (b):
an arc strip pressing die for a civil air defense door frame comprises an upper die and a lower die; the upper die comprises an upper die connecting block 2-1, a middle column 2-2, an upper die lower pressing plate 2-3 and an arc-shaped pressing plate 2-4; the lower die comprises a lower die base 1-1 and a lower die main body 1-2; the upper end of the middle column 2-2 is connected with the middle part of the upper die connecting block 2-1, and the lower end of the middle column 2-2 is connected with the middle part of the upper surface of the upper die lower pressing plate 2-3; the section of the arc-shaped pressing plate 2-4 is in a semi-ellipse shape, the upper part of the arc-shaped pressing plate 2-4 is a plane and is connected with the center of the upper die lower pressing plate 2-3, and the lower part of the arc-shaped pressing plate 2-4 is an arc-shaped surface; the lower part of the lower die main body 1-2 is connected with a lower die base 1-1, and the upper part of the lower die main body 1-2 is provided with an arc-shaped groove; the arc-shaped surface of the arc-shaped pressing plate 2-4 is matched with the arc-shaped groove at the upper part of the lower die main body 1-2.
And guide posts 2-5 are arranged on the two sides of the front end of the arc-shaped pressing plate 2-4 on the lower surface of the upper die lower pressing plate 2-3.
The rear end of the arc-shaped groove of the lower die main body 1-2 is provided with a baffle plate 1-3, and the left end and the right end of the baffle plate 1-3 are connected with the two ends of the arc-shaped groove of the lower die main body 1-2.
