[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Combined with attachment Figure 1-8 As shown, the present invention discloses a bending device, including an execution main frame 1, wherein the execution main frame 1 is provided with a cam piece 2, a sliding plate 3, and a bending propulsion structure 4 in sequence from bottom to top; the cam piece 2 is slidably connected to the sliding plate 3, and the sliding plate 3 is slidably connected to the bending propulsion structure 4. The present invention realizes that the cam piece 2 drives the sliding plate 3, and the sliding plate 3 is slidably connected to the bending propulsion structure 4 by arranging the cam piece 2 and the sliding plate 3 to be slidably connected, so that the cam piece 2 drives the sliding plate 3, and the sliding plate 3 further pushes the bending propulsion structure 4. The operation is simple, the structure is simple, and labor costs can be reduced. The cam piece 2 and the sliding plate 3 are preferably made of stainless steel.

[0026] In the specific technical solution of the present invention, a sliding through hole 5 is provided on the cam piece 2, a transmission bracket 6 is provided on the sliding plate 3, and a first rolling bearing 7 is provided at the lower end of the transmission bracket 6. The first rolling bearing 7 is slidably connected in the sliding through hole 5 to realize a slidable connection between the cam piece 2 and the sliding plate 3.

[0027] The sliding through hole 5 is in a "Z" shape as a whole and is divided into an upper through hole 8 and a lower through hole 9. The upper through hole 8 and the lower through hole 9 are connected. By setting the sliding through hole 5 in a "Z" shape as a whole and being connected, during operation, the first rolling bearing 7 can slide up and down by sliding in the upper through hole 8 and the lower through hole 9 of the sliding through hole 5, thereby driving the sliding plate 3 to slide up and down through transmission.

[0028] When the device of the present invention is specifically applied, the movement principle of the cam piece 2 and the sliding plate 3 is that the left and right sliding of the cam piece 2 is achieved by applying a force to the cam piece 2 to the left or right; when the cam piece 2 slides to the right, the first rolling bearing 7 slides from the lower through hole 9 of the sliding through hole 5 to the upper through hole 8, thereby driving the transmission bracket 6 to move upward, and then the transmission bracket 6 drives the sliding plate 3 to move upward, and the second rolling bearing 13 at the upper end of the transmission bracket 6 on the sliding plate 3 then slides from the lower end of the transmission through hole 12 to the upper end along the inclined transmission through hole 12, thereby promoting the bending and advancing The structure 4 is pushed forward, and the bending propulsion structure 4 contacts the element to be bent 28 to achieve bending of the element to be bent 28; when the cam plate 2 slides to the left, the first rolling bearing 7 slides from the upper through hole 8 of the sliding through hole 5 to the lower through hole 9, thereby driving the transmission bracket 6 to move downward, and then the transmission bracket 6 drives the sliding plate 3 to move downward, and the second rolling bearing 13 at the upper end of the transmission bracket 6 on the sliding plate 3 slides from the upper end of the transmission through hole 12 to the lower end along the inclined transmission through hole 12, thereby pushing the bending propulsion structure 4 to retract backward, thereby achieving the reset of the bending propulsion structure 4.

[0029] In the specific technical solution of the present invention, a cam piece positioning groove 10 is provided on the cam piece 2, and the cam piece 2 is connected to the execution main frame 1 through a nut, and the nut passes through the cam piece positioning groove 10. The setting of the cam piece positioning groove 10 allows the cam piece 2 to move left and right as needed, and preferably, the number of the cam piece positioning grooves 10 is two, which increases the stability of sliding.

[0030] The lower end of the bending propulsion structure 4 is provided with a propulsion bracket 11, and the lower end of the propulsion bracket 11 is provided with an inclined transmission through-hole 12, which is preferably set at a 45-degree angle. The upper end of the transmission bracket 6 is provided with a second rolling bearing 13, which is slidably disposed within the transmission through-hole 11. During actual use, the bending propulsion structure 4 is pushed forward or retracted by the second rolling bearing 13 on the transmission bracket 6 sliding up and down in the inclined transmission through-hole 12.

[0031] The sliding plate 3 is provided with a sliding plate positioning hole 14, and the sliding plate 3 is connected to the execution main frame 1 through a nut. The nut passes through the sliding plate positioning hole 14, and the sliding plate 3 can slide up and down along the nut. The sliding plate positioning hole 14 can be set to two on the left and right to enhance the stability of sliding.

[0032] In the specific technical solution of the present invention, the bending propulsion structure 4 includes a linear rail 15, which is arranged at the upper end of the execution main frame 1. The number of the linear rails 15 is preferably set to two. A sliding bracket 16 is provided on the linear rail 15, and the sliding bracket 16 is connected to the propulsion bracket 11. The sliding bracket 16 can slide along the linear rail 15. A propulsion bracket 17 is provided on the sliding bracket 16. The propulsion bracket 17 is connected to a push arm 18, and the push arm 18 is connected to a collision wheel 19. The collision wheel 19 is connected to the push arm 18 through a collision wheel shaft 20. The propulsion bracket 17 is also connected to a pressure block 21, and the pressure block 21 is located below the push arm 18.

[0033] The movement principle of the bending propulsion structure 4 is as follows: Since the second rolling bearing 13 is slidably disposed within the transmission through-hole 11, when the second rolling bearing 13 slides from the lower end to the upper end of the transmission through-hole 11, the propulsion bracket 11 drives the sliding bracket 16 forward along the two linear rails 15, thereby driving the impact wheel 19 in front of the push arm 18 to bend the bending element 28, and the pressure block 21 is used to fix the bending element 28. When the second rolling bearing 13 slides from the upper end to the lower end of the transmission through-hole 11, the propulsion bracket 11 drives the sliding bracket 16 backward along the two linear rails 15, thereby achieving reset.

[0034] In order to adjust the bending angle of the bending element 28, a cylinder bracket 22 is provided at the upper end of the execution main frame 1, and the cylinder bracket 22 is fixedly connected to the cylinder 23. The lower end of the cylinder 23 is connected to the adjustment block 24. The adjustment block 24 can be controlled by the cylinder 23 to press down the bent element 29 to adjust to the required bending angle, wherein the adjustment block 24 is preferably a cylindrical column.

[0035] Furthermore, a tension spring 25 is provided between the sliding plate 3 and the second rolling bearing 13 , which can appropriately adjust the tension between the sliding plate and the second rolling bearing 13 when the sliding plate slides, thereby enhancing the stability of the sliding.

[0036] It should be further explained that the device of the present invention also includes a thrust main frame 26, and a stop block 27 is provided at the upper end of the thrust main frame 26. One end of the stop block 27 protrudes upward 30. The thrust main frame 26 and the execution main frame 1 are connected to each other by splicing. The thrust main frame and the execution main frame are preferably arranged to have the same shape for easy cooperation. Through the cooperation of the thrust main frame 26, the component 28 to be bent is placed on the protrusion 30 on the stop block 27. Under the thrust of the impact wheel 19, the component 28 to be bent is bent into a bent component 29, and under the pressure of the adjustment block 24 at the lower end of the cylinder 23, the desired bending angle is achieved.

[0037] like Figure 1-8 , further illustrating the working principle of the present invention.

[0038] The execution main frame 1 of the present invention is spliced with the thrust main frame 26 so that the device is in a ready-to-work state, and the element 28 to be bent is placed between the execution main frame 1 and the thrust main frame 26. A stop block 27 is provided at the upper end of the thrust main frame 26, and one end of the stop block 27 protrudes upward 30. Specifically, the element 28 to be bent is placed on one side of the protrusion 30. When performing the bending work, by applying a rightward force to the cam piece 2, the cam piece 2 slides to the right, and the first rolling bearing 7 slides from the lower through hole 9 of the sliding through hole 5 to the upper through hole 8, thereby driving the transmission bracket 6 to move upward, and then the transmission bracket 6 drives the sliding plate 3 to move upward, and the second rolling bearing 13 at the upper end of the transmission bracket 6 slides from the lower end of the transmission through hole 12 to the upper end along the inclined transmission through hole 12, thereby pushing the bending propulsion structure 4 forward, and the sliding bracket 16 on the bending propulsion structure 4 moves forward along the two linear rails 15, driving the propulsion bracket 17, the propulsion bracket 17 is connected to the push arm 18, and the push arm 18 is connected to the impact wheel 19, and the lower end of the element 28 to be bent is on the side of the protrusion 30, and under the thrust of the impact wheel 19 in front of the push arm 18, the element 28 to be bent is bent, wherein the pressure block 21 is used to fix the element 28 to be bent.

[0039] After completing a single bending operation, the device needs to be reset first. Specifically, by applying a leftward force to the cam piece 2, the cam piece 2 slides to the left, and the first rolling bearing 7 slides from the upper through hole 8 of the sliding through hole 5 to the lower through hole 9, thereby driving the transmission bracket 6 to move downward, and then the transmission bracket 6 drives the sliding plate 3 to move downward, and the second rolling bearing 13 at the upper end of the transmission bracket 6 slides from the upper end of the transmission through hole 12 to the lower end along the inclined transmission through hole 12, thereby pushing the bending propulsion structure 4 to reset backward, that is, the sliding bracket 16 on the bending propulsion structure 4 retreats along the two linear rails 15, driving the propulsion bracket 17, the push arm 18 and the impact wheel 19 to reset, and then the next round of bending operation is performed after resetting.
