[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 9 The present invention provides a pipe thread rolling machine, which includes a base plate 1.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 9 A support frame 11 is fixedly installed on one side of the top of the base plate 1. A movable thread-rolling plate 5 for rolling the pipe fittings is movably installed on the support frame 11. A mounting frame 3 is movably connected to the other side of the top of the base plate 1. A fixed thread-rolling plate 6 for rolling the pipe fittings is inserted into the mounting frame 3. A feeding assembly 4 for supporting the pipe fittings is also provided on the mounting frame 3. The feeding assembly 4 includes a feeding ramp 41, which is fixedly connected to the top of the mounting frame 3. Side plates 43 are movably connected to both sides of the feeding ramp 41. A baffle 42 is provided on the side of the feeding ramp 41 closest to the support frame 11. The baffle 42 and the side plate 43 are connected to each other. The three sides are slidably connected; an electric push rod 422 is fixedly installed on the side of the baffle 42 away from the side plate 43, and a fixedly connected baffle plate 421 is installed at the bottom end of the electric push rod 422; a rotating rod 44 and a fixedly connected drive motor 45 are installed on the outer wall of the feeding inclined table 41; the two sides of the outer wall of the rotating rod 44 are threadedly connected to the inner wall of the corresponding side plate 43, and the thread directions of the two side thread structures are opposite; a fixedly connected driven gear 441 is sleeved in the center of the outer wall of the rotating rod 44; a drive gear 451 is fixedly installed at the output end of the drive motor 45, and the drive gear 451 meshes with the driven gear 441.

[0034] It should be noted that: with the setting of the feeding component 4, the operator can place multiple pipes that need to be threaded between the feeding ramp 41 and the side plate 43 in the feeding component 4. At this time, the pipes will move along the ramp towards the baffle 2 by their own force, thus completing the feeding of the pipes. Furthermore, by pre-storing multiple pipes, automatic feeding of pipes can be achieved, thereby reducing the feeding time of pipes and improving the working efficiency of the device.

[0035] In this embodiment: by threading the rotating rod 44 to the side plate 43, when the drive motor 45 drives the rotating rod 44 to rotate, the rotating rod 44 will drive the side plate 43 to move relative to or away from each other through the threaded structure with opposite thread directions on both sides, thereby adjusting the distance between the two side baffles 42. By adjusting the position of the side plate 43, the space above the loading ramp 41 can be changed, thus enabling the loading assembly 4 to flexibly support and load pipes of different lengths.

[0036] In the embodiments of this utility model, please refer to Figures 1 to 9 The mounting bracket 3 has a mounting groove 31 on the side near the support bracket 11. The mounting groove 31 has an insertion hole 311 inside. The inner wall of the mounting groove 31 abuts against the outer wall of the fixed thread rolling plate 6. An insertion rod 61 is fixedly installed on the outer wall of the fixed thread rolling plate 6. The outer wall of the insertion rod 61 abuts against the inner wall of the insertion hole 311 and is slidably connected. The end of the insertion rod 61 away from the fixed thread rolling plate 6 extends to the outside of the insertion hole 311 and has a slot 611. A card plate 62 is inserted into the inner wall of the slot 611. A docking magnetic plate 621 is fixedly connected to the bottom of the card plate 62. A fixed magnetic plate 71 is attracted to the bottom of the docking magnetic plate 621. A fixed piece 7 is fixedly connected to the bottom of the fixed magnetic plate 71, and the outer wall of the fixed piece 7 is fixedly connected to the outer wall of the mounting bracket 3.

[0037] It should be noted that by inserting the fixed thread rolling plate 6 into the mounting groove 31 and using the engagement of the clamping plate 62 with the clamping groove 611, the fixed thread rolling plate 6 can be quickly positioned. In subsequent use, if the fixed thread rolling plate 6 needs to be disassembled for inspection and maintenance, the clamping plate 62 can be lifted to separate it from the clamping groove 611, thereby releasing the limitation on the fixed thread rolling plate 6. At this time, the fixed thread rolling plate 6 can be directly pulled out from the mounting groove 31 for disassembly.

[0038] By attracting each other to the docking magnetic plate 621 and the fixed magnetic plate 71, the card plate 62 can be stably inserted into the card slot 611 during the installation of the fixed magnetic plate 71, thus achieving stability limiting of the installation of the fixed magnetic plate 71.

[0039] In the embodiments of this utility model, please refer to Figures 1 to 9The support frame 11 is equipped with a rotatably connected lead screw 12. A sliding block 13 is fitted between the lead screw 12 and the mounting frame 3. The inner wall of the sliding block 13 is threadedly connected to the outer wall of the lead screw 12. The inner wall of the sliding block 13 abuts against and is slidably connected to the outer wall of the mounting frame 3. The outer wall of the sliding block 13 abuts against the inner wall of the movable thread rolling plate 5. A fixed guide plate 52 is installed on the outer wall of the sliding block 13. A slidingly connected limit frame 51 is inserted inside the fixed guide plate 52. The end of the limit frame 51 abuts against and is slidably connected to the inner walls of the movable thread rolling plate 5 and the sliding block 13. A fixed spring 53 is installed between the limit frame 51 and the fixed guide plate 52.

[0040] It should be noted that the movable thread rolling plate 5 is installed by inserting the limit bracket 51. When the movable thread rolling plate 5 needs to be disassembled, replaced or repaired, the limit bracket 51 can be pulled to slide out from the movable thread rolling plate 5 and the movable block 13, thereby releasing the limit on the connection between the movable thread rolling plate 5 and the movable block 13. Then the movable thread rolling plate 5 can be lifted upwards to disassemble it.

[0041] With the spring 53, when the movable thread rolling block is sleeved on the outer wall of the movable block 13, the spring 53 will drive the limiting frame 51 to move towards the movable thread rolling plate 5 through its own force, so that the limiting frame 51 can be stably inserted into the movable thread rolling plate 5 to stably limit the installation of the movable thread rolling plate 5.

[0042] In the embodiments of this utility model, please refer to Figures 1 to 9 A support plate 32 is fixedly installed on the top of the base plate 1 near the mounting bracket 3. A sliding bracket 312 is inserted inside the support plate 32 and a cylinder 321 is fixedly connected between the sliding bracket 312 and the support plate 32. A baffle 2 is fixedly connected on the top of the base plate 1 near the support bracket 11. The outer wall of the baffle 2 is on the same vertical plane as the outer wall of the movable thread rolling plate 5. An inclined plate 21 is fixedly connected on the side of the baffle 2 near the mounting bracket 3 and the outer wall of the baffle 2 is fixedly connected to the outer wall of the baffle 42.

[0043] It should be noted that: during use, the baffle 2 will block the falling pipe fitting, thus ensuring that the falling pipe fitting is stably positioned above the fixed thread rolling plate 6. When the moving thread rolling plate 5 moves and squeezes the outer wall of the pipe fitting, it can drive the pipe fitting to move stably. With the installation of the inclined plate 21 on the baffle 2, when the threaded pipe fitting falls from the moving thread rolling plate 5 and the fixed thread rolling plate 6, the inclined plate 21 can guide the processed pipe fitting, allowing it to roll smoothly towards the mounting frame 3. This reduces the phenomenon of pipe fittings accumulating and blocking under the moving thread rolling plate 5 and the fixed thread rolling plate 6, and also makes it easier for workers to pick up materials.

[0044] The working principle of the pipe thread rolling machine provided by this utility model is as follows:

[0045] When using this device, the operator can place the pipe to be processed on the feeding ramp 41 in the feeding assembly 4. The added pipe will move along the feeding ramp 41 towards the baffle 2 by gravity. Then, the electric push rod 422 can be controlled to drive the baffle plate 421 to move downward to block the subsequent pipe and prevent the pipe from falling outside the baffle 2 and accumulating.

[0046] Next, the lead screw 12 can be controlled to rotate. The rotating lead screw 12 will drive the moving thread rolling plate 5 to move through the moving block 13. When the outer wall of the moving thread rolling plate 5 abuts against the outer wall of the pipe fitting, the pipe fitting will be driven to move downward until it falls off along the fixed thread rolling plate 6, thus completing the thread rolling of the pipe fitting. Then, the lead screw 12 can be controlled to rotate in the opposite direction, thereby resetting the moving thread rolling plate 5. After the moving plate is reset, the electric push rod 422 can be controlled to drive the baffle plate 421 to move upward, so that the pipe fitting located on the loading ramp 41 can be removed from the loading ramp 41. Then, the above steps are repeated to realize the cyclic operation of this device.

[0047] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0048] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
