[0023] Example:

[0024] like Figures 1-6 As shown, the embodiment of the present invention provides a rotary arm type bending press, comprising a side bracket 1, a lower rotary shaft 2, an upper rotary shaft 3, a supporting wheel 4, a left mounting frame 5, a rotary punching beam 6, a right mounting frame 7, an oil cylinder 8, a fixing seat 9, a pressing plate 10 and a pressure bed 12. The left mounting frame 5 is installed on the right side of the side bracket 1, the right mounting frame 7 is installed on the right side of the left mounting frame 5, and a pressure bed 12 is fixedly provided below the left mounting frame 5 and the right mounting frame 7. The oil cylinder 8 is fixedly installed on the left mounting frame 5 and the right mounting frame 7 through a flange. The upper rotary shaft 3 is passed on the push rod of the oil cylinder 8 of the left mounting frame 5. A lower rotating shaft 2 is installed on the pressure bed 12, and a rotating stamping beam 6 is sleeved on the lower rotating shaft 2 and the upper rotating shaft 3. A supporting wheel 4 is provided at the tail end of the rotating stamping beam 6. A supporting rail 17 is fixedly provided on the inner lower side of the left mounting frame 5, and the supporting wheel 4 rolls on the supporting rail 17. A lifting hole 601 is provided at the front end of the rotating stamping beam 6. A fixing seat 9 is installed on the push rod of the oil cylinder 8 of the right mounting frame 7, and a fixing card 16 is fixed on the fixing seat 9. A lower pressing die 15 is fixed on the pressure bed 12 by bolts, and an upper pressing die 14 is fixed on the rotating stamping beam 6 by a pressing plate 10.

[0025] By providing the lower rotating shaft 2 and the upper rotating shaft 3, when the steel plate is bent, the steel plate enters between the upper pressing die 14 and the lower pressing die 15, and the upper pressing die 14 cooperates with the lower pressing die 15 to bend the steel plate into a cylindrical shape. After the bending is completed, by loosening the fixing clamp 16, the rotary punching beam 6 is rotated along the lower rotating shaft 2 and the upper rotating shaft 3, and the rotary punching beam 6 drives the upper pressing die 14 and the steel plate bent into a cylindrical shape on the rotary punching beam 6 to rotate, so that the cylindrical steel plate is separated from the upper pressing die 14 and the lower pressing die 15. Between the dies 15, the rotating stamping beam 6 supports the bent cylindrical steel plate. The contact area between the rotating stamping beam 6 and the cylindrical steel plate is smaller than the contact area between the cylindrical steel plate and the upper die 14 and the lower die 15, which reduces friction and makes it more convenient to remove the cylindrical steel plate. When the cylindrical steel plate is taken out, it will not contact the upper die 14 and the lower die 15, preventing the friction between the cylindrical steel plate and the upper and lower dies 15 from causing damage to the upper die 14 and the lower die 15.

[0026] In this embodiment, the upper die 14 is stepped, and the bottom of the rotary stamping beam 6 matches the upper surface of the pressing plate 10. The pressing plate 10 is L-shaped and hooked. The right side surface of the rotary stamping beam 6 is provided with a plurality of holes that match the pressing plate 10. When the pressing plate 10 is fixed on the rotary stamping beam 6 by bolts, the hook-shaped portion of the pressing plate 10 is embedded in the hole of the pressing plate 10, which is convenient for the upper die.

[0027] In this embodiment, the support track 17 is arc-shaped, and the arc corresponding to the support track 17 is equal to 90°, which ensures the normal rotation of the rotary stamping beam 6, and the support track 17 can support the rear end of the rotary stamping beam 6 to ensure the horizontal state of the rotary stamping beam 6, facilitate the support wheel 4 on the rotary stamping beam 6 to rotate along the support track 17, and facilitate the removal of the bent steel plate from the upper die 14 below the rotary stamping beam 6.

[0028] In this embodiment, the lifting hole 601 matches the fixed card 16, and when the rotary stamping beam 6 rotates to the dynamic stamping position, the lifting hole 601 coincides with the position of the fixed card 16, which facilitates the fixed card to fix the position of the 16-degree rotating stamping beam 6, thereby achieving the effect of fixing the position of the upper die 14, and preventing the rotary stamping beam 6 from rotating along the lower rotating axis 2 and the upper rotating axis 3 during the stamping operation.

[0029] In this embodiment, a crossbeam 13 is fixedly provided on the inner side of the bottom of the left mounting frame 5 and the right mounting frame 7 to ensure the stability of the position of the left mounting frame 5 and the right mounting frame 7.

[0030] In this embodiment, a safety grating 11 is installed between the upper die 14 and the lower die 15. When the grating detects an abnormality, human hands and other equipment cannot operate or stop suddenly to ensure safety.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
