Description

Technical Field

[0001] This utility model relates to a processing equipment, and more particularly to a pipe bending forming equipment. Background Technology

[0002] Pipe bending equipment is an industrial machine used to bend metal pipes, plastic pipes and other pipes into specific shapes. It is widely used in pipe processing. Its core function is to deform the pipe through external force to achieve precise bending angles and curvatures.

[0003] Existing pipe bending forming equipment does not have a bending position locking function. For pipes of different models or with different bending positions, the processing workers can only rely on experience. As a result, the bending position of the processed pipes is likely to vary greatly, affecting the quality of the products and causing trouble for the manufacturers. Utility Model Content

[0004] Therefore, it is necessary to provide a pipe bending forming device to address the shortcomings of existing technologies.

[0005] A pipe bending forming device includes a base, a bending assembly mounted on the base, and a positioning assembly mounted on the base and located on one side of the bending assembly. During bending, the pipe passes through the bending assembly, and the positioning assembly controls the length of the pipe passing through the bending assembly, thereby controlling the bending position. The bending assembly includes a positioning seat with a through hole. The positioning assembly includes a guide rail, a slider slidably mounted on the guide rail, a support seat located behind the guide rail, a bushing mounted on the support seat, a screw located behind the slider and mounted on the bushing, and an adjusting wheel mounted on the screw. The adjusting wheel is located at the end of the screw away from the slider, and the slider and the positioning seat are opposite to each other. The bushing has an internally threaded hole, and the screw is threadedly mounted on the internal hole of the bushing, limiting the slider from the rear.

The first locking screw passes through the gasket, linkage plate, die head, another linkage plate, another gasket, fixing plate, and base block from the top position and is then engaged with the locking nut. The drive rod is mounted on the end of the two linkage plates away from the die head. The drive rod drives the linkage plates to rotate around the first locking screw. During the rotation of the linkage plates, the pressure roller rotates synchronously.

[0007] In one embodiment, the bending assembly further includes a second locking screw. The pressure roller is horizontally positioned between the die head and the drive rod, and vertically positioned between the two linkage plates. The second locking screw passes through the linkage plate and the pressure roller sequentially from above and is mounted on the other linkage plate. The pressure roller can rotate around the second locking screw.

[0008] In one embodiment, the third locking screw passes through the edge of the die head and is mounted on the fixing plate, and the third locking screw limits the position of the die head.

[0009] In one embodiment, the die head is provided with a pressure groove, which is disposed on the outer peripheral surface of the die head.

[0010] In one embodiment, the grooves around the die head are distributed along the entire outer peripheral surface of the die head.

[0011] In one embodiment, the groove is arc-shaped in the cross-sectional direction, and the curvature is consistent with the outer diameter of the pipe to be bent.

[0012] In one embodiment, the positioning seat is mounted on the base block.

[0013] The beneficial effects of this utility model's pipe bending forming equipment are as follows: Based on the bending assembly, a positioning assembly is further added.

[0022] Please see Figures 1 to 4 This utility model provides a pipe bending forming device for bending a long, round pipe 100. The pipe bending forming device includes a base 30, a bending component 10 mounted on the base 30, and a positioning component 20 mounted on the base 30 and located on one side of the bending component 10. During bending, the pipe 100 passes through the bending component 10, and the positioning component 20 controls the length of the pipe 100 passing through the bending component 10, thereby controlling the bending position.

[0023] The bending assembly 10 includes a base block 11, a fixing plate 12, two gaskets 13, two linkage plates 14, a die head 15, a first locking screw 16, a locking nut 111, a second locking screw 18, a pressure roller 17, a drive rod 19, and a third locking screw 110. The base block 11 is mounted on the base 30, and the fixing plate 12 is mounted on the base block 11. The ends of the two linkage plates 14 are respectively located on the upper and lower sides of the die head 15. The two gaskets 13 are located on the upper and lower sides of the two linkage plates 14. The first locking screw 16 passes through the gasket 13, linkage plate 14, die head 15, another linkage plate 14, another gasket 13, and fixing plate 12 from the top position and is then engaged with the locking nut 111. The third locking screw 110 passes through the edge of the die head 15 and is mounted on the fixing plate 12. The third locking screw 110 limits the movement of the die head 15 to prevent it from rotating. The linkage plate 14 can rotate around the axis of the first locking screw 16.

[0024] The pressure roller 17 is horizontally positioned between the die head 15 and the drive rod 19, and vertically positioned between the two linkage plates 14. The second locking screw 18 passes through the linkage plate 14 and the pressure roller 17 sequentially from above and is mounted on the other linkage plate 14. The pressure roller 17 can rotate around the second locking screw 18. The drive rod 19 is simultaneously mounted on the two linkage plates 14 at the end away from the die head 15 by welding or other means. The drive rod 19 drives the linkage plate 14 to rotate around the first locking screw 16. During the rotation of the linkage plate 14, the pressure roller 17 rotates synchronously.

[0025] The die head 15 is generally shaped like a disc, and has a pressing groove 151 on it. The pressing groove 151 is located on the outer peripheral surface of the die head 15 and is distributed around the axis of the die head 15 along the entire outer peripheral surface of the die head 15. The groove 151 is arc-shaped in the cross-sectional direction, and the curvature is consistent with the outer diameter of the pipe 100 to be bent.

[0026] In addition, the present invention also includes a positioning seat 112, which is mounted on the base block 11 and has a through hole 113.

[0027] The positioning assembly 20 includes a guide rail 21, a slider 22 slidably mounted on the guide rail 21, a support base 23 located behind the guide rail 21, a bushing 24 mounted on the support base 23, a screw 25 located behind the slider 22 and mounted on the bushing 24, and an adjusting wheel 26 mounted on the screw 25. The adjusting wheel 26 is located at the end of the screw 25 away from the slider 22, and the slider 22 is positioned opposite to the positioning seat 112. The bushing 24 has an internally threaded hole, and the screw 25 is threadedly mounted on the internal hole of the bushing 24, limiting the slider 22 from the rear.

[0028] During pipe bending, the position of the screw 25 is adjusted according to the bending position. The screw 25 limits the slider 22 from the rear, thereby controlling the length of the pipe 100 passing through the bending assembly. The pipe 100 is then passed between the pressure roller 17 and the die head 15, and passes through the through hole 113 on the positioning seat 112 and is pressed against the slider 22. Then, the drive rod 19 is rotated, which drives the pressure roller 17 to rotate around the die head 15. During the rotation of the pressure roller 17 around the die head 15, the pressure roller 17 drives the pipe 100 to bend around the pressure groove 151 of the die head 15.

[0029] The beneficial effects of this utility model's pipe bending forming equipment are as follows: Based on the bending assembly 10, a positioning assembly 20 is further provided. The slider 22 of the positioning assembly 20 can be slidably adjusted, and the screw 25 limits the slider 22 from the rear. During bending, the mating position of the screw 25 and the slider 22 is adjusted according to the bending position of the pipe 100. The pipe 100 passes through the bending assembly 10, and the positioning assembly 20 controls the length of the pipe 100 passing through the bending assembly 10, thereby controlling the bending position. This utility model has a flexible overall structure, which can be adjusted according to the bending position of the pipe 100, and the pipes 100 have good consistency after bending, making it highly practical.
