Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pipe bender, especially to a feeding mechanism of multifunctional numerical control pipe bender. BACKGROUND

[0002] In modern industrial production, pipe bending is widely used in automobile manufacturing, aerospace, pipeline engineering and other industries. With the development of industrial technology, the performance and automation level of pipe benders are constantly improving. As an important part of the pipe bender, the performance of the feeding mechanism directly affects the efficiency and quality of pipe bending.

[0003] Early pipe benders are mostly manually fed, which is labor-intensive, slow and low-precision, and cannot meet the needs of large-scale and high-efficiency production. Although the development of automation technology has brought semi-automatic and fully-automatic feeding mechanisms, it has improved the feeding efficiency to some extent, but still has many problems:

[0004] The traditional feeding mechanism has fixed or limited adjustable range of clamping block spacing, poor pipe fitting adaptability, and cannot effectively limit the position of the pipe when facing diversified pipe processing needs, which may cause the pipe to deviate, shake or even fall during transportation, affecting the feeding and the entire processing flow. The moving and positioning accuracy of some feeding mechanism components is low, making it difficult to accurately move to the specified position above the pipe, and the clamping may deviate. The feeding and discharging control is not accurate, which cannot meet the high-precision pipe bending requirements. During pipe transportation, due to the lack of effective limiting and resistance reduction measures, the pipe is greatly affected by friction, making the transportation not smooth or even jammed, which reduces the processing precision and quality, causes the pipe surface to wear, shortens the service life, increases the cost, and the inaccurate positioning makes it difficult to accurately send the pipe to the processing area, further affecting the processing efficiency and quality.

[0038] Working principle:

[0039] The pipe to be machined is placed on the top of the pipe support 2, according to the size of the pipe, the hand wheel 434 is rotated to drive the screw rod 432 to rotate, thereby driving the clamping block 433 to move, so as to flexibly adjust the distance between the two clamping blocks 433 and realize accurate fitting.

[0040] With the cooperation of the guide rail one 3 and the guide rail slider one 31, the related components on the top are pushed to the target position above the pipe support 2, so that the support plate 35 is accurately positioned above the pipe to be clamped. The telescopic hydraulic mechanical arm 34 is controlled to push the support plate 35 downward to the pipe, then the clamping jaw push rod 352 is started to drive the clamping jaw body 351 to approach and clamp the pipe. Then, the hydraulic mechanical arm 34 is used to lift the support plate 35 to move the pipe away from the top of the pipe support 2, and then the front and rear telescopic hydraulic mechanical arm 33 is used to push the support plate 35 forward to transport the pipe to the top of the guide rail two 4.

Then, the clamping jaw body 351 is lifted by the clamping jaw push rod 352, so that the pipe is loosened, and the placing operation is completed.

[0042] After the pipe is placed on the workbench 43 and the top of the guide wheel 45, the pipe is pushed forward into the positioning groove 52 by the guide rail slider 41 and the guide rail 4.
