Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as Figures 1 to 4 As shown, the hemming mechanism of the cylinder in this implementation includes a base 10, a cylinder 1, a tray 2, a turntable 6, a pressure roller 7, an outer pressure roller 41, an inner pressure roller 51, a first cam 52, a second cam 45. First roller 531, second roller 422, driven rod 53, sliding sleeve 56, guide rod 55, first spring 54, second spring 46, bearing 42, drive motor 44, rotating shaft 43 and bearing 22.

[0018] Wherein, a cylinder 1 is fixed on the base 10, and the end of the piston rod of the cylinder 1 is rotated through a bearing 22 to be provided with a tray 2 for placing the cylinder body 3 that needs to be hemmed. The raised portion 21 inserted into the inner wall of the cylinder body 3, by setting the raised portion 21, the fixed support of the cylinder body 3 on the tray 2 is improved, ...

Abstract

The invention discloses an edge folding mechanism which comprises a base. The edge folding mechanism is characterized in that an air cylinder is fixed to the base, the end of a piston rod of the air cylinder is rotationally provided with a tray through a bearing, the tray is used for containing a barrel needing to be subject to edge folding, a rotary disc is arranged over the tray in a rotational manner, and the diameter of the rotary disc is matched with the internal diameter of the barrel; and a taper inner compression roller moving back and forth in the radial direction of the barrel is arranged on the inner side of the barrel and on the upper side of the rotary disc, and an outer compression roller swinging back and forth is arranged at the position, corresponding to the inner compression roller, of the outer side of the barrel.

Description

technical field [0001] The invention relates to an edge folding mechanism. Background technique [0002] In metalworking, the hemming of metal cylinders is often encountered. If the edge is folded by manual extrusion, the labor intensity of the operator is high, the production efficiency is low, and the edge is prone to unevenness after the edge is folded, which will affect the popularization and application of the metal cylinder after the edge is folded. [0003] For this reason, the Chinese invention with the existing publication number CN105618535A discloses "Metal Cylinder Folding Machine", which includes a base, a left hydraulic cylinder, a right hydraulic cylinder, a left stamping head, a right stamping head, a left support and a right support, The left hydraulic cylinder, the right hydraulic cylinder, the left support and the right support are all arranged on the base, the left stamping head is connected with the piston rod of the left hydraulic cylinder, the right s...
