[0003] The object of the present invention is to provide an IBC ton barrel frame bending system, which can realize the synchronous movement of multiple bending actions and has the effect of improving the bending efficiency.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: an IBC ton barrel frame bending system, comprising a frame, a plurality of bending mechanisms and clamping members, the bending mechanism comprising a double-headed cylinder fixedly connected to the frame, a primary bending arm and a secondary bending arm, the primary bending arm comprising a driving arm, a transmission member, and a primary guide arm; the secondary bending arm comprising a push rod, a secondary connecting rod, and a secondary guide arm; the end of the driving arm is rotatably connected to the driving end of the double-headed cylinder, and the other end is rotatably connected to the transmission member, the end of the push rod is rotatably connected to an end of the transmission member away from the driving arm, the part of the transmission member located between the driving arm and the push rod is rotatably connected to the frame, the primary guide arm is rotatably connected to the frame, one end of the secondary connecting rod is rotatably connected to the end of the push rod, and the other end is connected to the secondary guide arm, the end of the primary guide arm away from the transmission member is rotatably connected to the middle of the secondary connecting rod, and a plurality of clamping members are arranged on the same side of the primary guide arm and the secondary guide arm.

[0005] By adopting the above technical scheme, the first-stage bending arm is driven to move by the double-headed cylinder, and the first-stage bending arm will further drive the second-stage bending arm to move simultaneously. This method can achieve the effect of one-step driving and two-step simultaneous bending, thereby improving the bending efficiency of the frame. First, the double-headed cylinder will drive the driving arm to pull the conveying member connected to the frame to rotate. During the rotation of the conveying member, the first-stage guide arm connected to one end of the conveying member will be driven to rotate, and the push rod connected to the other end will also be driven to move. The further movement of the push rod and the first guide arm will drive the second-stage guide arm connected to the first guide arm and the push rod to rotate synchronously.

[0007] By adopting the above technical solution, when the double-headed cylinder controls the rotation of the conveying member through the driving arm, the driving arm will drive the first conveying arm to rotate around a fixed position. The first conveying arm and the second conveying arm are fixed at an angle, which will drive the second conveying arm to rotate in the same rotation direction (counterclockwise or clockwise at the same time), thereby achieving a synchronous driving effect. The ends of the first conveying arm and the second conveying arm are also connected through the third conveying arm, which can improve the rotation stability.

[0008] The present invention is further configured as follows: a movable groove is provided on the third conveying arm, and the primary guide arm passes through the movable groove and is rotatably connected to the frame.

[0009] By adopting the above technical solution, since the first-level guide arm requires a certain rotation space, the movable groove can make the first-level guide arm rotate smoothly without restriction.

[0010] The present invention is further configured as follows: the primary guide arm comprises a primary guide block and a primary guide rod, the primary guide block and the primary guide rod are integrally formed, and the guide rod is bent toward the secondary connecting rod and rotatably connected thereto;

[0013] By adopting the above technical solution, it can be achieved that in the unfolded state, the first-level guide block and the second-level guide arm are located on the same straight line with the bracket on the side away from the push rod, so that the frame to be processed can be conveniently placed on the frame, and then the frame is clamped by the clamping part to start the bending mechanism to achieve one-step bending.

[0014] The present invention is further configured as follows: bending mechanisms are provided on both sides of the frame, and the double-headed cylinder drives the bending mechanisms on both sides to move synchronously.

[0015] By adopting the above technical solution, bending operations can be performed simultaneously from both ends of the frame.

[0017] The present invention is further configured as follows: the driving member includes a driving cylinder, a synchronization rod, and a guide rod, the synchronization rod is fixedly connected to the piston end of the driving cylinder, a groove is axially provided on the synchronization rod, and the two guide rods are radially fixedly connected in the groove, and a sliding groove is provided on the upper and lower clamping jaws, and the two guide rods are respectively slidably embedded in the two sliding grooves.

[0018] The present invention is further configured as follows: a claw holding portion is provided at the end of the clamping jaw, the claw holding portion is arranged in an arc shape, and the inner wall cross section is circular when the upper and lower claw holding portions are in contact.

[0019] By adopting the above technical solution, the driving cylinder drives the synchronization rod to move up and down. When the synchronization plate moves up and down, the guide rod in the synchronization rod slot will drive the clamping claw to flip through the sliding groove. A synchronization rod is provided with a guide rod, which can synchronously drive multiple clamping claws to perform synchronous clamping.

[0020] The beneficial effects of the present invention are as follows: the primary bending arm is driven to move by the double-headed cylinder, and the primary bending arm will further drive the secondary bending arm to move simultaneously. This method can achieve the effect of one-step driving and two-step simultaneous bending, thereby improving the bending efficiency of the frame. First, the double-headed cylinder will drive the driving arm to pull the conveying member connected to the frame around the rotation. During the rotation of the conveying member, the primary guide arm connected to one end of the conveying member will be driven to rotate, and the push rod connected to the other end will also be driven to move.

[0032] Examples, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an IBC ton barrel frame bending system includes a frame 1, a plurality of bending mechanisms and a clamping member 5, wherein the bending mechanism includes a double-headed cylinder 2, a primary bending arm 3 and a secondary bending arm 4 fixedly connected to the frame 1, wherein the primary bending arm 3 includes a driving arm 31, a transmission member 32 and a primary guide arm 33; the secondary bending arm 4 includes a push rod 41, a secondary connecting rod 42 and a secondary guide arm 43; the end of the driving arm 31 is rotatably connected to the driving end of the double-headed cylinder 2, and the other end is rotatably connected to the transmission member 32; the end of the push rod 41 is rotatably connected to the driving end of the double-headed cylinder 2 At the end of the transmission member 32 away from the driving arm 31, the part of the transmission member 32 located between the driving arm 31 and the push rod 41 is rotatably connected to the frame 1, the primary guide arm 33 is rotatably connected to the frame 1, one end of the secondary connecting rod 42 is rotatably connected to the end of the push rod 41, and the other end is connected to the secondary guide arm 43, the end of the primary guide arm 33 away from the transmission member 32 is rotatably connected to the middle of the secondary connecting rod 42, and a plurality of the clamping members 5 are arranged on the same side of the primary guide arm 33 and the secondary guide arm 43. The first-stage bending arm 3 is driven to move by the double-headed cylinder 2, and the first-stage bending arm 3 will further drive the second-stage bending arm 4 to move simultaneously. This method can achieve the effect of one-step driving and two-step simultaneous bending, thereby improving the bending efficiency of the frame. First, the double-headed cylinder 2 will drive the driving arm 31 to pull the conveying member 32 connected to the frame 1 to rotate. During the rotation of the conveying member 32, the first-stage guide arm 33 connected to one end of the conveying member 32 will be driven to rotate, and the push rod 41 connected to the other end will also be driven to move. The further movement of the push rod 41 and the first guide arm will drive the second-stage guide arm 43 connected to the first guide arm and the push rod 41 to rotate synchronously.

Bending mechanisms are provided on both sides of the frame 1, and the double-headed cylinder 2 drives the bending mechanisms on both sides to move synchronously. Bending operations can be performed simultaneously from both ends of the frame.

[0035] like Figure 6 , Figure 7 , Figure 8 As shown, the clamping member 5 includes a fixed block 51, a clamping jaw 52, ​​and a driving member. The fixed block 51 is fixedly connected to the primary guide arm 33 and the secondary guide arm 43. A rotating rod 521 is provided on the side of the clamping jaw 52. The clamping jaw 52 is rotatably connected to the fixed block 51 through the rotating rod 521. The driving member drives the two clamping jaws 52 to rotate around the rotating rod 521 so as to move closer to or away from each other. The driving member includes a driving cylinder 53, a synchronization rod 54, and a guide rod 55. The synchronization rod 54 is fixedly connected to the piston end of the driving cylinder 53.

[0036] The working principle of an IBC ton barrel frame bending system is as follows: a first-stage bending arm 3 is driven to move by a double-headed cylinder 2, and the first-stage bending arm 3 further drives the second-stage bending arm 4 to move simultaneously. This method can achieve the effect of one-step driving and two-step simultaneous bending, thereby improving the bending efficiency of the frame. First, the double-headed cylinder 2 drives the driving arm 31 to pull and rotate a conveying member 32 connected to a frame 1. During the rotation of the conveying member 32, a first-stage guide arm 33 connected to one end of the conveying member 32 is driven to rotate, and a push rod 41 connected to the other end is also driven to move. Further movement of the push rod 41 and the first guide arm drives the second-stage guide arm 43 connected to the first guide arm and the push rod 41 to rotate synchronously. This method can achieve synchronous movement of multiple bending actions, thereby improving the bending efficiency.
