DETAILED DESCRIPTION

[0023] Embodiment 1

[0024] like Figure 1-Figure 3 As shown, a tricycle canopy frame bending machine proposed in this embodiment includes a mounting bracket a1, a mounting bracket b2, a power assembly, a limit plate 10, a conveyor belt mechanism, two sets of transmission members a and two sets of transmission members b.

[0025] Two groups of transmission parts a are respectively installed on both sides of the mounting bracket a1, and the transmission part a includes a chain b62 and multiple sprockets b61. The multiple sprockets b61 are rotatably installed on the mounting bracket a1. The chain b62 is meshed and connected with the multiple sprockets b61, and the transmission path of the chain b62 is rectangular. Multiple lower molds 11 are installed between the two groups of transmission parts a. Both ends of the lower mold 11 are connected to the chains b62 on both sides. The lower mold 11 is opened at one end, and the inner cavity of the lower mold is a downwardly concave arc surface structure. The opening of the lower mold can clamp the steel pipe.

[0026] The mounting bracket b2 is arranged at the upper end of the mounting bracket a1, and two groups of transmission members b are respectively installed on both sides of the mounting bracket b2. The transmission member b includes a chain a52 and a plurality of sprockets a51. The plurality of sprockets a51 are rotatably mounted on the mounting bracket b2. The chain a52 is meshed and connected with the plurality of sprockets a51, and the transmission path of the chain a52 is rectangular. A plurality of elastic pressing mechanisms are installed between the two groups of transmission members b. The elastic pressing mechanisms include an upper pressing die 12, a connecting rod 15 and an elastic reset member. Both ends of the connecting rod 15 are connected to the chains a52 on both sides. The upper pressing die 12 is connected to the connecting rod 15 through an elastic reset member. The elastic reset member includes a guide rod 16, a hemispherical block 17 and a spring 18. The guide rod 16 is connected to the upper die 12, and the guide rod 16 movably passes through the connecting rod 15 and its end is connected to the hemispherical block 17. The spring 18 is sleeved and installed on the guide rod 16. When the hemispherical block 17 contacts the raised part on the limit plate 10, due to the limiting effect, the guide rod 16 starts to move downward until it moves to the horizontal position on the limit plate 10. The movement of the guide rod 16 drives the upper die 12 to move downward. When the hemispherical block 17 is separated from the limit plate 10, the upper die 12 is driven to reset under the elastic force of the spring 18; the limit plate 10 is arranged between the two sets of transmission parts b, and the limit plate 10 is connected to the mounting bracket b2, and one side of the limit plate 10 is an upwardly tilted structure.

[0027] The power assembly is mounted on the mounting bracket a1 and is used to drive the two groups of transmission members a and the two groups of transmission members b to move synchronously. The power assembly includes a motor 7, a transmission shaft 8 and four groups of transmission members c. The motor 7 is mounted on the side of the mounting bracket a1. The transmission shaft 8 is rotatably mounted on the mounting bracket a1 and its end is connected to the output shaft of the motor 7. The transmission member c includes a driving sprocket 91, a chain c92 and a driven sprocket 93. The four driving sprockets 91 are all mounted on the transmission shaft 8. The four driven sprockets 93 are respectively mounted on the two groups of transmission members a and the two groups of transmission members b. The two driven sprockets 93 at the upper end are respectively connected to the rotating shafts of the sprockets a51 on both sides, and the two driven sprockets 93 at the lower end are respectively connected to the rotating shafts of the sprockets b61 on both sides. The driving sprocket 91 and the driven sprocket 93 at the same vertical position are connected by chains c92. The motor 7 drives the transmission shaft 8 to rotate, and the transmission shaft 8 drives the four driving sprockets 91 to rotate. With the cooperation of the chain c92, the four driven sprockets 93 are driven, and the four driven sprockets 93 respectively drive the two chains a52 and the two chains b62 to rotate.

[0028] The conveyor belt mechanism 4 is located below the transmission member a. When the pressed steel pipe starts to rotate downward, the steel pipe inside the lower template 11 falls onto the conveyor belt mechanism 4 under the action of gravity. The conveyor belt mechanism 4 can transport the fallen steel pipe to the next workstation.

[0029] A horizontal support plate 13 is provided between the two transmission members a, and the horizontal support plate 13 is connected to the mounting bracket a1. The horizontal support plate 13 is used to support and limit the lower template 11 to prevent the chain b62 from breaking during the pressing process.

[0030] In this embodiment, the power component drives the two chains a52 and the two chains b62 to rotate, and the moving speed of the chain a52 is the same as the moving speed of the chain b62. When the upper die 12 moves to the position of the limit plate 10, the elastic reset part on the upper die 12 first contacts the raised part of the limit plate 10, forcing the upper die 12 to move downward. During the downward movement of the upper die 12, the steel pipe in the lower template 11 is pressed and formed. When the elastic reset part on the upper die 12 is separated from the limit plate 10, the upper die 12 is quickly reset upward under the elastic force of the elastic reset part, and then the upper die 12 is moved out from the inner side of the lower template 11. When the lower template 11 starts to rotate downward, under the action of gravity, the pressed and formed steel pipe falls from the inner side of the lower template 11 onto the conveyor belt mechanism 4 and is transported away.

[0031] Embodiment 2

[0032] like Figure 1 and Figure 2 As shown, a tricycle canopy frame bending machine proposed in this embodiment, compared with embodiment 1, in this embodiment, a material box 3 is provided on one side of the mounting bracket b2, and the material box 3 is installed at the upper end of the mounting bracket a1, and a discharge hole is provided at the bottom end of the material box 3, and multiple steel pipes that need to be bent are concentrated on the inner side of the material box 3, and the discharge hole provided at the bottom end of the material box 3 is only for the discharge of a single steel pipe; multiple lower molds 11 are connected with anti-drop rods 14, and the anti-drop rods 14 on both sides of the lower mold 11 are staggered. When the opening on the lower template 11 is aligned with the discharge hole of the material box 3, the steel pipe inside the material box 3 automatically falls into the inner side of the lower template 11, thereby completing the automatic feeding work, and the multiple anti-drop rods 14 are in a horizontally arranged state after rotating to the upper end position of the transmission member a, which is used to prevent the steel pipe inside the material box 3 from falling into the position between two adjacent lower templates 11.
