When feeding the sheet material, it is basically pulled by the end of the corrugated pipe one-piece molding equipment or fed by the unwinding mechanism. However, when feeding in these two ways, the sheet material is slightly bent due to the inconsistency of the unwinding material and the discharging speed, which affects the bending strength of the metal bellows product.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, the metal bellows one-piece forming equipment includes a base 1, a fixing frame 2 is symmetrically fixedly installed at the end of the base 1, a fixing rod 3 is fixedly installed on the top of the fixing frame 2, and a first limit plate 4 and a second limit plate 5 are slidably installed on the outer side of the fixing rod 3, and the ends of the first limit plate 4 and the second limit plate 5 are both provided with sliding holes 6, and the sliding holes 6 are slidably connected to the fixing rod 3. Corresponding feeding grooves 7 are provided in the middle of the first limit plate 4 and the second limit plate 5, and the sheet material passes through the two feeding grooves 7. The feeding side of the fixing rod 3 is symmetrically installed with squeezing rollers 8 for pressing the sheet material, and the distance between the two squeezing rollers 8 will change due to the discharge speed of the sheet material, which is used to tighten the sheet material.

[0020] like Figures 1 to 4 As shown, a fixing column 9 is fixedly installed on the outer side of the fixing rod 3 corresponding to the lower side of the first limit plate 4 and on the outer side of the fixing rod 3 corresponding to the upper side of the second limit plate 5. The fixing column 9 above the second limit plate 5 is arranged higher than the highest moving end of the second limit plate 5. An insertion rod 10 is fixedly installed on the outer side of the fixing column 9. A rotating plate 11 is rotatably installed on the outer side of the insertion rod 10. A gear ring 12 is fixedly installed on the outer side of the rotating plate 11. The upper and lower gear rings 12 on the same side are meshed and connected. The insertion rod 10 is arranged through the gear ring 12. The two rotating plates 11 at the same height are rotatably connected to the extrusion roller 8 respectively through axle pins. A tensioning spring 13 is fixedly installed on the upper surface of one of the rotating plates 11 at the top, and the end of the tensioning spring 13 away from the rotating plate 11 is fixedly connected to the fixing rod 3.

[0021] When the sheet material is discharged through the discharge mechanism, the sheet material is continuously in a tensioned state, and the tensioning spring 13 will pull one of the rotating plates 11, thereby driving the upper squeezing roller 8 to squeeze the sheet material. Due to the engagement between the two gear rings 12, the four rotating plates 11 will be driven to rotate on the outside of the insertion rod 10, thereby changing the distance between the two squeezing rollers 8, and thereby tensioning the sheet material.

[0022] like Figures 1 to 4 As shown, a mounting plate 14 is symmetrically fixedly installed on the upper surface of the base 1 at a position corresponding to the position between the two fixing frames 2, and a guide roller 15 is rotatably installed between the two mounting plates 14 through an axle pin, and the guide roller 15 is arranged on one side corresponding to the two feed troughs 7.

[0023] The sheet-like raw material can be smoothly guided into between the two feeding troughs 7 by the arrangement of the guide roller 15 .

[0024] like Figures 1 to 4 As shown, the bottom plane of the feed trough 7 on the first limiting plate 4 is arranged tangent to the guide roller 15 .

[0025] Prevent the sheet-like raw material from excessively rubbing against the ends of the feed slots 7 on the first limiting plate 4 and the second limiting plate 5 .

[0026] like Figures 1 to 4 As shown, a limiting rod 16 is symmetrically fixedly installed on the upper surface of the first limiting plate 4, and a limiting hole 17 is opened on the second limiting plate 5 at a position corresponding to the limiting rod 16. The limiting hole 17 is slidably connected to the limiting rod 16. An extrusion spring 18 is sleeved on the outer side of the top end of the limiting rod 16. One end of the extrusion spring 18 is fixedly connected to the top of the limiting rod 16, and the other end of the extrusion spring 18 is fixedly connected to the upper surface of the second limiting plate 5.

[0027] By adjusting the distance between the first limiting plate 4 and the second limiting plate 5 , the second limiting plate 5 is driven to move up and down along the trajectory of the limiting rod 16 , so as to adapt to sheet materials of different thicknesses.

[0028] like Figures 1 to 4 As shown, the squeezing roller 8 and the guide roller 15 are both made of wear-resistant materials.

[0029] Prevent the sheet material from rubbing against the squeezing roller 8 and the guide roller 15, which results in a short service life of the squeezing roller 8 and the guide roller 15.

[0030] The utility model provides a metal bellows integrated forming device, and the specific working principle is as follows:

[0031] When the device is in use, the sheet material is passed through the two squeezing rollers 8, the guide roller 15, and the feed slot 7 in the middle of the first limit plate 4 and the second limit plate 5 in sequence. When the sheet material is discharged through the discharge mechanism, the sheet material is continuously in a tensioned state, and the tensioning spring 13 will pull one of the rotating plates 11, thereby driving the upper squeezing roller 8 to squeeze the sheet material. Due to the meshing between the two gear rings 12, the four rotating plates 11 will be driven to rotate on the outside of the insertion rod 10, thereby changing the distance between the two squeezing rollers 8, and thereby tightening the sheet material. When the sheet material is discharged faster due to this, resulting in a supply exceeding demand of the corrugated tube integrated molding device, one of the rotating plates 11 will be pulled again by the tensioning spring 13, which will further adjust the distance between the two squeezing rollers 8 The distance is used to tighten the sheet material. When the sheet material is discharged slowly and the supply of the corrugated tube one-piece molding equipment is less than the demand, the sheet material itself squeezes the two squeezing rollers 8, which will drive the four rotating plates 11 to rotate on the outside of the insertion rod 10, reducing the distance between the two squeezing rollers 8 to adapt to the material usage speed of the corrugated tube one-piece molding equipment. The wok can readjust the distance between the two squeezing rollers 8 when the material is changed next time. When the corrugated tube one-piece molding equipment is fed, the sheet material will pass through the feeding groove 7 in the middle of the first limit plate 4 and the second limit plate 5. When processing sheet materials of different thicknesses, the distance between the first limit plate 4 and the second limit plate 5 can be adjusted to drive the second limit plate 5 to rise and fall along the trajectory of the limit rod 16 to adapt to sheet materials of different thicknesses.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
