Description

Technical Field

[0001] This utility model relates to the field of pipe fitting cutting technology, specifically a cutting device for processing pipe fittings. Background Technology

[0002] Pipe fitting cutting devices are specialized equipment used for precise cutting of pipes and their fittings. The cutting device mainly consists of a support frame, guide rails and sliders, a motor and cutting disc, and a control box. In use, the pipe fitting is first placed on the support frame of the cutting device and its position is adjusted to ensure cutting accuracy. Then, the motor is started, driving the cutting disc to rotate. The rotation speed and cutting depth of the cutting disc are adjusted as needed. Finally, the cutting disc is moved to cut along the contour of the pipe fitting.

[0003] For example, Chinese patent CN218080683U, entitled "A Cutting and Processing Device for Automotive Pipe Fittings," includes a processing table, on which is provided an anti-compression deformation cutting table for supporting automotive pipe fittings and a cutting mechanism for cutting automotive pipe fittings placed on the anti-compression deformation cutting table; the anti-compression deformation cutting table includes at least: a support table; an elastic support mechanism disposed on the processing table for elastically supporting the support table; and an elastic adjustment structure for adjusting the supporting elastic force of the elastic support mechanism on the support table.

[0004] While the existing technologies can cut pipe fittings, in practical use, on the one hand, it is difficult to fix the pipe fittings. When the cutting disc cuts the pipe fittings, the friction between the cutting disc and the pipe fitting causes the pipe fitting to easily shift on the placement table, thus affecting the cutting accuracy. On the other hand, the clamping mechanism is not flexible enough. Usually, the clamping mechanism is fixed on the base, making it difficult to adjust the clamping mechanism to a position that fits pipe fittings of different sizes, thus reducing the adaptability of the clamping mechanism. Therefore, it does not meet the current needs. In response, we propose a cutting device for processing pipe fittings. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses an L-shaped clamping plate and a pressing plate to clamp and fix pipe fittings. When fixing the pipe fittings, the L-shaped clamping plate has been adjusted to a suitable position. Then, the pipe fittings are placed on the upper end of the horizontal plate of the L-shaped clamping plate. Then, the rotating rod is rotated, so that the rotating rod drives the connecting plate and the pressing plate to move downward together through the external thread until the rubber pad at the lower end of the pressing plate contacts and presses against the outer wall of the pipe, thereby fixing the pipe fittings between the pressing plate and the L-shaped clamping plate, avoiding the pipe fittings from shifting position during cutting.

[0015] 2. This utility model uses a lead screw and a servo motor to move the plate in the horizontal direction. Before fixing the pipe fitting, the position of the moving plate is adjusted according to the length of the pipe fitting. At this time, the servo motors on both sides are turned on simultaneously, so that the output shaft of the servo motor drives the lead screw to rotate. The lead screw drives the moving plate to move towards each other in the slide groove through the external thread. At this time, the moving plate drives the L-shaped clamping plate and the extrusion plate to move together towards the center of the cutting table until the moving plates on both sides move to the appropriate position. Then, the pipe fitting is placed between the moving plates, and the cutting position of the pipe fitting is located below the cutting disc, thereby improving the adaptability of the clamping mechanism to fixing pipe fittings of different lengths.

[0016] 3. This utility model, by providing a second hydraulic telescopic device, can adjust the distance between the L-shaped clamping plates. Before fixing the pipe fitting, the position of the L-shaped clamping plates is adjusted according to the diameter of the pipe fitting. At this time, the second hydraulic telescopic device is activated, causing the telescopic end of the second hydraulic telescopic device to extend. The extension of the telescopic end of the second hydraulic telescopic device drives the L-shaped clamping plate and the extrusion plate to move together towards the center of the cutting table until the distance between the L-shaped clamping plates matches the pipe fitting. Then, the L-shaped clamping plate and the extrusion plate together fix the pipe fitting, thereby improving the adaptability of the clamping mechanism to fixing pipe fittings with different diameters.

The front and rear ends of the upper end of the movable plate 6 are fixedly provided with fixed seats 7, which facilitates the movement of the movable plate 6 in the sliding groove 3 by the lead screw 5.

[0026] Please see Figure 2 and Figure 3A second hydraulic telescopic device 20 is fixedly installed at one end of the fixed base 7 near the outer side of the movable plate 6. The telescopic end of the second hydraulic telescopic device 20 extends to the other end of the fixed base 7, and the telescopic end of the second hydraulic telescopic device 20 is fixedly connected to the L-shaped clamping plate 8, so as to facilitate the movement of the L-shaped clamping plate 8 by driving the second hydraulic telescopic device 20.

[0027] Please see Figure 1 and Figure 2 The cutting table 2 is located on one side of the slide 3 and is equipped with servo motors 4 at both the front and rear ends. The output shaft of the servo motor 4 extends into the slide 3 and is fixedly connected to the lead screw 5, so that the lead screw 5 can be driven to rotate by the servo motor 4.

[0028] Please see Figure 1 and Figure 4 Rubber pads 12 are fixedly installed at the upper end of the horizontal plate of the L-shaped clamping plate 8 and the lower end of the extrusion plate 9, so as to increase the friction between the extrusion plate 9, the L-shaped clamping plate 8 and the pipe fittings through the rubber pads 12.

[0029] Please see Figure 1 A mounting bracket 14 is provided at the center of the upper end of the cutting table 2. A cutting groove 13 is provided inside the center of the cutting table 2.

[0031] Working principle: Before fixing the pipe fitting, adjust the position of the moving plate 6 according to the length of the pipe fitting. At this time, the servo motors 4 on both sides are turned on simultaneously, so that the output shaft of the servo motor 4 drives the lead screw 5 to rotate. The lead screw 5 drives the moving plate 6 to move towards each other in the slide groove 3 through the external thread. At this time, the moving plate 6 drives the L-shaped clamping plate 8 and the extrusion plate 9 to move together towards the center position of the cutting table 2 until the moving plates 6 on both sides move to the appropriate position. Then, place the pipe fitting between the moving plates 6, and the cutting position of the pipe fitting is located below the cutting disc 18. Adjust the position of the L-shaped clamping plate 8 according to the hole diameter of the pipe fitting. At this time, turn on the second hydraulic telescopic device 20, so that the telescopic end of the second hydraulic telescopic device 20 extends. The extension of the telescopic end of the second hydraulic telescopic device 20 drives the L-shaped clamping plate 8 and the extrusion plate 9 to move together towards the center position of the cutting table 2 until the distance between the L-shaped clamping plates 8 is adapted to the pipe fitting. Then, the L-shaped clamping plate 8 and the extrusion plate 9 are used together to fix the pipe fitting.
