[0002] In the production and processing of metal pipe fittings, pipe fittings usually need to go through a cutting process; existing pipe cutting devices mostly use saw discs to cut pipe fittings, and in the process of cutting pipe fittings, they usually cut from the outside of the pipe fittings to the inside. Due to the squeezing effect of the saw disc, it is easy to cause the cut part of the pipe fitting to be concave, thereby affecting the cutting effect and making it inconvenient for the subsequent grinding process of the pipe mouth; in addition, existing cutting devices usually cut pipe fittings continuously, which easily causes the temperature of the saw disc and the cut part of the pipe fittings to be too high, thereby affecting the cutting quality.

[0023] 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.

[0024] Example 1

[0025] See also Figure 1-Figure 5 The present invention provides a technical solution: a pipe cutting device, including a workbench 1, on which two limit seats 2 and a clamping assembly 3 are arranged, the two limit seats 2 are arranged in parallel and at intervals, and the limit seats 2 are adapted to the metal pipe to be cut (hereinafter referred to as the pipe); the pipe is placed horizontally on the two limit seats 2, and is clamped by the clamping assembly 3, that is, the pipe is clamped between the limit seats 2 and the clamping assembly 3.

[0026] A horizontal moving component 8 is also provided on the workbench 1. The horizontal moving component 8 is connected to an adjusting component 7, and a support frame 6 is connected to the adjusting component 7. The horizontal moving component 8 can drive the adjusting component 7 to move horizontally, thereby driving the support frame 6 on the adjusting component 7 to move horizontally, and the adjusting component 7 is used to drive the support frame 6 to rotate and reset; at the same time, the support frame 6 is provided with a driving component 5, the driving component 5 is connected to the saw disk 4, and the driving component 5 is used to drive the saw disk 4 to rotate; in the initial state, the saw disk 4 is used to extend into the interior of the pipe, and at this time the saw disk 4 is coaxial with the pipe.

[0027] The driving assembly 5 includes a driving shaft 52, one end of which is movably connected to the support frame 6 through a bearing, and the other end of the driving shaft 52 is fixedly connected to the saw disk 4, and the driving shaft 52 is coaxial with the saw disk 4; the driving assembly 5 also includes a driving motor 51, and the driving motor 51 is installed on the support frame 6; the output shaft of the driving motor 51 is fixedly connected to one end of the driving shaft 52 away from the saw disk 4, and the output shaft of the driving motor 51 is coaxial with the driving shaft 52; by driving the driving shaft 52 to rotate by the driving motor 51, the saw disk 4 can be driven to rotate.

[0028] The clamping assembly 3 includes a lifting device 31, which is arranged on the workbench 1; a connecting seat 32 is connected to the lifting device 31, and the lifting device 31 is used to drive the connecting seat 32 to move up and down; two clamping seats 33 are fixedly arranged on the connecting seat 32, and the two clamping seats 33 are arranged in parallel and at intervals; the two clamping seats 33 are arranged in a one-to-one correspondence with the two limit seats 2, and the clamping seats 33 are also adapted to the pipe fittings; specifically, the clamping seats 33 and the limit seats 2 are both provided with arc grooves adapted to the pipe fittings, and the pipe fittings are clamped in the arc grooves; in the initial state, the clamping seat 33 is located at a suitable height above the limit seat 2; when placing and fixing the pipe fittings, the position of the pipe fittings can be adjusted according to the cutting position by placing the pipe fittings flat on the two limit seats 2 and allowing the saw disk 4 to pass through the pipe fittings; after the pipe clamp position adjustment is completed, the connecting seat 32 and the clamping seat 33 on the connecting seat 32 are driven downward by the lifting device 31, thereby achieving clamping of the pipe fittings.

[0029] The adjusting assembly 7 includes a support seat 71, which is connected to a horizontal moving assembly 8. The horizontal moving assembly 8 can drive the support seat 71 to move horizontally in a straight line. An adjusting motor 74 is installed on the support seat 71. The output shaft of the adjusting motor 74 penetrates the support seat 71 and is sleeved with a driving gear 75. The driving gear 75 is fixedly connected to the output shaft of the adjusting motor 74. An adjusting shaft 72 is also movably provided on the support seat 71. The adjusting shaft 72 is movably connected to the support seat 71 through a bearing. One end of the adjusting shaft 72 is fixedly connected to the support frame 6. The axis of the adjusting shaft 72 The axis of the drive shaft 52 deviates, that is, the adjusting shaft 72 is not coaxial with the drive shaft 52; a driven gear 73 is sleeved on the outside of the adjusting shaft 72, and the driven gear 73 is fixedly connected to the adjusting shaft 72; the driven gear 73 is meshed with the driving gear 75, and the transmission ratio between the driving gear 75 and the driven gear 73 is greater than 1; the adjusting motor 74 adopts a stepping motor, which can realize the control of step direction, speed and rotation angle; since the driving gear 75 and the driven gear 73 are also provided, the rotation direction and rotation angle of the support frame 6 can be controlled by adjusting the motor 74.

[0030] In this embodiment, after the pipe is clamped and fixed, the driving motor 51 drives the driving shaft 52 to rotate, further driving the saw disk 4 to rotate; then, the adjusting motor 74 works and drives its output shaft to rotate in one of the rotation directions (clockwise or counterclockwise), and the adjusting motor 74 drives the driving gear 75 to rotate, and the driving gear 75 and the driven gear 73 drive the adjusting shaft 72 to rotate, thereby driving the support frame 6 to rotate. Figure 4 As shown, the support frame 6 rotates at an angle of no more than 90 degrees. During the rotation of the support frame 6, the drive assembly 5 and the saw disk 4 are driven to rotate. During the rotation of the support frame 6, the saw disk 4 can be driven to move toward the outside of the pipe and cut the pipe, and a part of the pipe is cut. After the support frame 6 is rotated into place, the motor 74 is adjusted to adjust the rotation direction to drive the support frame 6 to rotate in the opposite direction. The 90 degrees of reverse rotation does not exceed 180 degrees. Figure 5As shown, during this process, the saw disk 4 is reset and then rotated, and another part of the pipe is cut by the saw disk 4, and the parts of the pipe cut twice are connected (specifically, this can be achieved by setting a saw disk 4 with a suitable outer diameter; or by setting the adjusting shaft 72 at a suitable position, that is, the adjusting shaft 72 and the drive shaft 52 have a suitable distance, the parts of the pipe cut twice can also be connected); after the support frame 6 is rotated in the opposite direction and into position, the adjusting motor 74 adjusts the rotation again and drives the support frame 6 to reset, that is, drives the drive assembly 5 and the saw disk 4 to reset; finally, the support seat 71 is driven to move horizontally and linearly through the horizontal moving assembly 8, and the support seat 71 drives the support frame 6, the drive assembly 5 and the saw disk 4 to move horizontally and linearly, and makes the saw disk 4 move toward the uncut part of the pipe. During the movement of the saw disk 4, the remaining part of the pipe can be cut, and the pipe is cut into two parts; similarly, this can be achieved by setting a saw disk 4 with a suitable outer diameter, or by setting the adjusting shaft 72 at a suitable position, so that the remaining part of the pipe can be ensured to be completely cut.

[0031] In this embodiment, each time the saw disc 4 cuts the pipe, it cuts the pipe from the inside out; thereby, during the cutting process, the saw disc 4 is prevented from squeezing the pipe and causing the pipe to become concave (when the pipe is concave, it is inconvenient to subsequently grind and remove burrs from the pipe mouth, and the cutting quality is also reduced); at the same time, the pipe undergoes three cutting processes, making the cutting process discontinuous, thereby avoiding continuous cutting that causes the saw disc 4 and the cut part of the pipe to be too high in temperature; since the saw disc 4 is more prone to wear or breakage due to excessively high temperature, and the cut position of the pipe is too stable to cause warping and deformation, this embodiment helps to improve the cutting quality through several discontinuous cuttings.

[0032] In addition, in this embodiment, the pipe is cut outward, so even if the cut portion of the extruded pipe is deformed outward to a certain extent, the convex state is more convenient for subsequent grinding and deburring of the pipe mouth than the concave state of the cut portion of the pipe.

[0033] Example 2

[0034] See also Figure 6 This embodiment is based on the first embodiment, and the driving assembly 5 also includes a limiting sleeve 53 mounted on the outside of the driving shaft 52; the limiting sleeve 53 is coaxial with the driving shaft 52; one end of the limiting sleeve 53 is fixedly set on the support frame 6, and the driving shaft 52 is movably connected to the limiting sleeve 53 through a bearing; through the above arrangement, the supporting effect on the driving shaft 52 is improved, thereby improving the stability of the saw disk 4; of course, the outer diameter of the limiting sleeve 53 is smaller than the inner diameter of the pipe, and during the cutting process, the limiting sleeve 53 will not interfere with the pipe.

[0035] Example 3

[0036] See again Figure 2This embodiment is based on the second embodiment. The horizontal moving component 8 and the lifting device 31 both use linear modules, which are existing technologies. The two linear modules are both installed on the workbench 1. The two linear modules are used to drive the support seat 71 to move horizontally and linearly, and at the same time drive the connecting seat 32 to move up and down linearly.
