The tool removes excess metal from the workpiece to be processed and, under the premise of controlling productivity and cost, enables the workpiece to obtain geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements. To achieve this process, metal pipe cutting processing equipment is needed.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following examples are used to illustrate the present invention but are not intended to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed in the present invention.

[0025] See also Figures 1-10The present invention provides a cutting processing equipment for metal pipe fittings, comprising a workbench 1, both sides of the top of the workbench 1 are fixedly connected with a side seat 2, the inner side of the side seat 2 is rotatably connected to a rotating frame 3, the inner sides of both ends of the rotating frame 3 are rotatably connected to a rotating ring 4, a plurality of connecting rods 9 are fixedly connected between the two rotating rings 4 on the inner side of the same rotating frame 3, a rack 5 is fixedly connected to the top of the rotating ring 4 on the inner side of the two rotating frames 3 away from each other, a number of arc grooves 7 are provided on the inner side of the rotating ring 4, a number of arc grooves 7 are provided on the inner side of the rotating ring 4, a sliding rod 8 is slidably connected to the inner side of the arc groove 7, the sliding rods 8 on both sides of the rotating frame 3 are fixedly connected to a fixed frame 10 and a connecting frame 12 on the side away from each other, the inner side of the fixed frame 10 is rotatably connected to a driving roller 11, and the end of the connecting frame 12 away from the corresponding sliding rod 8 is fixedly connected to a clamping plate 13 for clamping the metal pipe fitting, and a position suitable position is provided on the inner side of each end of the rotating frame 3 The gears 12 are connected to the drive shaft 3 at the same time, and the gears 12 are connected to the drive shaft 3 at the same time.

[0026] Place the metal pipe in the rotating rack 3 of the left side seat 2 so that it is located on the inner side of the driving roller 11, start the No. 3 motor to drive the driving roller 11 to rotate, and transport the pipe to the inside of the device so that the other end of the pipe enters the other rotating rack 3 until it reaches the appropriate cutting position. The two No. 1 motors are started synchronously to drive the No. 1 gear 6 to rotate. Through the engagement of the rack 5, the connecting rod 9 and the rotating rings 4 on both sides rotate, and the sliding rod 8 moves inward under the limit of the limit frame 19 through the arc groove 7, so that the driving roller 11 and the clamping plate 13 move inward to clamp the pipe.

[0027] The two rotating frames 3 are respectively located on both sides of the cutting part of the metal pipe, providing stable support for the pipe, ensuring that the pipe will not shake or shift during the processing, thereby ensuring the accuracy and quality of the processing. When the rotating ring 4 rotates, the arc groove 7 will push the slide bar 8 to move inward. The cooperation of the rotating ring 4 and the connecting rod 9 can ensure that the slide bars 8 on both sides always keep moving synchronously, ensuring that the splint 13 and the driving roller 11 can apply force inward evenly, thereby firmly clamping metal pipes of different sizes, avoiding processing errors caused by uneven clamping, and through the rotation of the driving roller 11, the pipe can be moved to or from the processing position more smoothly, reducing the tediousness of manual operation and reducing labor intensity.

[0028] By driving the rotating frame 3 to rotate through the ring gear 15, the metal pipe does not need to be frequently adjusted in position or re-clamped during the processing, which greatly reduces the processing time and operation steps. This all-round processing capability can ensure that all parts of the pipe are evenly cut and processed, avoiding quality problems caused by insufficient or excessive local processing, thereby significantly improving the processing efficiency and processing quality. Through the guiding effect of the limit frame 19, the clamping plate 13 and the driving roller 11 can move smoothly inward or outward, which not only ensures the reliability of the clamping process, but also ensures that the pipe remains stable during the processing, and will not affect the processing accuracy or cause processing accidents due to the instability of the clamping device.
