Abstract
Description
Technical Field
[0001] This utility model relates to a thread rolling device, specifically a highly applicable thread rolling device, and belongs to the technical field of thread rolling devices. Background Technology
[0002] A thread rolling device is a device used to process threads on a metal round bar. It is also called a thread rolling machine. It uses two relatively rotating rolling dies to clamp the metal round bar in the middle. Through the extrusion and rolling of the thread rolling wheels, the surface of the workpiece is plastically deformed, thereby forming threads on the round bar.
[0003] When a metal bar is long, it is prone to plastic deformation during handling, resulting in bending. This plastic deformation is difficult to observe with the naked eye. When thread rolling is performed on a slightly deformed metal bar, the bent bar will wobble significantly during feeding, leading to uneven thread formation and affecting thread rolling accuracy. Furthermore, when processing metal bars of different diameters, the wobble will be even more pronounced if the limiting components are not adjusted. Therefore, we provide a highly adaptable thread rolling device. Utility Model Content
[0004] This utility model proposes a highly applicable thread rolling device, including a support platform, the support platform including a plate, a slide rail mechanism provided on the top surface of the support platform, a thread rolling assembly for thread rolling on the slide rail mechanism, and an adjustable guide mechanism provided on the top surface of the plate.
[0005] Specifically, the thread rolling assembly includes two sets of fixing plates. A motor A is fixed to the side of each set of fixing plates. Thread rolling wheels are fixed to the output ends of both motors A. The combination of the fixing plates, motors A, and thread rolling wheels enables thread processing on metal round bars.
[0006] The adjustable guide mechanism includes a mounting frame fixed to the top surface of the platform. A hydraulic cylinder with its output end pointing downwards is fixed on the mounting frame. A horizontal plate is fixed to the output end of the hydraulic cylinder. Two motors B are fixed to the bottom surface of the horizontal plate. Guide wheels A, B, and C are sequentially fixed to the output ends of the two motors B. A connecting frame is fixed to the top surface of the horizontal plate. A guide member is fixed to the other end of the connecting frame. Guide holes are sequentially distributed from top to bottom on the side of the guide member.
[0007] Specifically, two symmetrical sliding rods are fixed on the top surface of the horizontal plate. Both sliding rods pass through the top surface of the mounting frame and extend to the top of the mounting frame. A sliding cylinder that is slidably connected to the side of the sliding rod is fixed on the top surface of the mounting frame. The cooperation between the sliding rod and the sliding cylinder makes the movement of the horizontal plate more stable.
[0008] Specifically, the left side of the guide member is fixed with multiple bucket-shaped covers corresponding to the positions of the guide holes from top to bottom. The bucket-shaped covers can guide the metal rod and make it easier for it to enter the guide holes.
[0009] Furthermore, the top surface of the platform is fixed with a sliding groove, and the top surface of the sliding groove is provided with a recess to provide good support for the metal rod.
[0010] Furthermore, four support plates are fixed to the bottom surface of the platform to provide a suitable working height for the platform.
[0011] The aforementioned slide rail mechanism includes an adjustment rail fixed to the top surface of the platform, and a sliding plate is provided on the adjustment rail. The position of the thread rolling assembly can be adjusted by the cooperation of the adjustment rail and the sliding plate.
[0012] The beneficial effects of this application are as follows:
[0013] I. This highly adaptable thread rolling device, through its adjustable guide mechanism, allows two motors B to drive two guide wheels A, B, and C to rotate, thereby guiding the metal bar and preventing it from wobbling significantly when rolling threads through the thread rolling wheels, which could lead to uneven thread formation.
[0014] Second, this highly adaptable thread rolling device, through its adjustable guide mechanism, allows the hydraulic cylinder to drive the horizontal plate to move up and down slightly. Simultaneously, the horizontal plate drives guide wheels A, B, and C to move up and down slightly, enabling thread rolling of metal round bars of different diameters, thus achieving high applicability.

[0025] like Figures 1-4 As shown, this utility model embodiment provides a highly applicable thread rolling device, including a support platform 1, the support platform 1 including a plate 101, a groove 102 fixed on the top surface of the plate 101, and a groove formed on the top surface of the groove 102. The groove 102 is provided to provide good support for the metal rod and reduce the possibility of further bending. Four support plates 103 are fixed on the bottom surface of the plate 101 to provide a suitable working height for the plate 101.
[0026] Please refer to this carefully. Figures 1-3 The top surface of the support platform 1 is provided with a slide rail mechanism 2. The slide rail mechanism 2 includes an adjustment rail 201 fixed on the top surface of the platform 101. The adjustment rail 201 is a linear motion device driven by electricity, consisting of a motor, a lead screw and a controller. The controller controls the motor to drive the lead screw to rotate, and the sliding plate 202 is used to adjust the thread rolling assembly 3. The adjustment rail 201 is provided with a sliding plate 202. The position of the thread rolling assembly 3 can be adjusted by the cooperation of the adjustment rail 201 and the sliding plate 202.
[0027] Please refer to this carefully. Figures 1-3 The slide rail mechanism 2 is equipped with a thread rolling assembly 3 for thread rolling. The thread rolling assembly 3 includes two sets of fixing plates 301. A motor A302 is fixed on the side of each set of fixing plates 301. Thread rolling wheels 303 are fixed to the output ends of both motors A302. The start of the motors A302 can drive the thread rolling wheels 303 to rotate. Through the squeezing and rolling of the thread rolling wheels 303, the surface of the metal round bar is plastically deformed, thereby forming threads. The fixed plates 301, motors A302 and thread rolling wheels 303 are arranged in a coordinated manner to perform thread processing on the metal round bar.
[0028] Please refer to this carefully. Figure 3 and Figure 4An adjustable guide mechanism 4 is provided on the top surface of the platform 101. The adjustable guide mechanism 4 includes a mounting frame 401 fixed on the top surface of the platform 101. A hydraulic cylinder 402 with its output end pointing downward is fixed on the mounting frame 401. A horizontal plate 403 is fixed to the output end of the hydraulic cylinder 402. Two motors B404 are fixed to the bottom surface of the horizontal plate 403. Guide wheels A405, B406 and C407 are fixed to the output ends of the two motors B404 in sequence. A connecting frame 408 is fixed to the top surface of the horizontal plate 403. A guide member 409 is fixed to the other end of the connecting frame 408. Guide holes 410 are distributed from top to bottom on the side of the guide member 409.
[0029] Specifically, the activated hydraulic cylinder 402 drives the horizontal plate 403 to move vertically. The horizontal plate 403 then drives the guide wheels A405, B406, and C407 to move up and down slightly. The guide wheels A405, B406, and C407 are positioned to allow for thread rolling of metal bars of different diameters. The metal bars are inserted into the guide hole 410 under the guidance of the bucket-shaped cover 413. Then, two motors B404 are activated, rotating in opposite directions. The two motors B404 drive the two guide wheels A405, B406, and C407 to rotate respectively. The opposing rotation of the guide wheels A405, B406, and C407, in conjunction with the guide hole 410, guides the metal bars, preventing them from wobbling significantly when passing through the thread rolling wheel 303, which could lead to uneven thread formation.
[0030] Two symmetrical sliding rods 411 are fixed on the top surface of the horizontal plate 403. Both sliding rods 411 pass through the top surface of the mounting frame 401 and extend to the top of the mounting frame 401. A sliding cylinder 412 is fixed on the top surface of the mounting frame 401 and is slidably connected to the side of the sliding rods 411. During the process of the hydraulic cylinder 402 driving the horizontal plate 403 to rise and fall, the sliding rods 411 will also slide on the sliding cylinder 412. The cooperation between the sliding rods 411 and the sliding cylinder 412 can make the horizontal plate 403 move more stably. Multiple bucket-shaped covers 413 corresponding to the positions of the guide holes 410 are fixed on the left side of the guide member 409 from top to bottom. The bucket-shaped covers 413 can guide the metal rod and make it easier to enter the guide hole 410, avoiding the situation where the metal rod cannot be aligned with the guide hole 410.
[0031] Working Principle: During operation, hydraulic cylinder 402 is first activated to drive horizontal plate 403 to move up and down slightly. Horizontal plate 403 then drives guide wheels A405, B406, and C407 to move up and down slightly. The position of guide wheels A405, B406, or C407 is adjusted according to the corresponding diameter of the metal bar to improve its applicability. The two motors B404 rotate in opposite directions. Activating these two motors drives guide wheels A405, B406, and C407 to rotate, guiding the metal bar and preventing significant wobbling when it passes through thread rolling wheel 303. Simultaneously, two motors A302 are activated, driving the two thread rolling wheels 303 to rotate. The compression and rolling action of the thread rolling wheels 303 causes plastic deformation on the surface of the metal bar, thus completing the processing and forming threads on its surface.
