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.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 This utility model provides a wire rolling device for metal processing, comprising: a workbench 1 with a through groove in the middle; a CNC box 9 fixedly mounted on the workbench 1; a fixed end plate 2 fixedly mounted on the workbench 1 and located on one side of the through groove, with two sets of electric rods 3 symmetrically mounted on the top of the fixed end plate 2, and a movable end plate 4 fixedly mounted on the telescopic ends of the two sets of electric rods 3; a double-mold wire rolling mechanism 5 fixedly mounted on the side of the fixed end plate 2 and the movable end plate 4 facing the through groove; a cooling mechanism 6 fixedly mounted on the fixed end plate 2 for cooling the wire rolling; and a return tank 7 embedded in the through groove, with a circulation pump 8 connected to the cooling mechanism 6 fixedly mounted on one side of the return tank 7; the circulation pump 8, the double-mold wire rolling mechanism 5, and the two sets of electric rods 3 all electrically connected to the CNC box 9.

[0028] The dual-mode thread rolling mechanism 5 includes a U-shaped mounting frame 51, which is mounted on the fixed end plate 2 and the movable end plate 4. A rotary cylinder 52 is fixedly mounted on one end of the U-shaped mounting frame 51, and a thread rolling steel plate 53 is fixedly mounted on the output end of the rotary cylinder 52. A thread rolling rod 54 is rotatably mounted on the back of the thread rolling steel plate 53, and a drive motor 55 for driving the thread rolling rod 54 to rotate is mounted on the back of the thread rolling steel plate 53. The end of the thread rolling steel plate 53 away from the rotary cylinder 52 is rotatably connected to the U-shaped mounting frame 51 through a support shaft.

[0029] The fixed end plate 2 and the U-shaped mounting bracket 51 are detachably connected directly by screws. The movable end plate 4 has a sliding plate 41 that is mated with the U-shaped mounting bracket 51 and is slidably mounted on its end face. The movable end plate 4 has a through groove, and two sets of support rods 42 are installed in the through groove. A transmission plate 43 is slidably mounted on the two sets of support rods 42. The transmission plate 43 is fixedly connected to the sliding plate 41. A hydraulic rod 44 is fixedly mounted on the other end of the movable end plate 4. The telescopic end of the hydraulic rod 44 is fixedly connected to the transmission plate 43.

[0030] It should be noted that during use, according to the external thread rolling process, when thread rolling is required using a rolling plate, the double-mold thread rolling mechanism 5 of the fixed end plate 2 and the movable end plate 4 is controlled by the CNC box 9 to rotate the rolling steel plate 53 to the end facing the through groove via the rotary cylinder 52. Then, the rod to be processed is placed between the two rolling steel plates 53, and the electric rod 3 drives the two rolling steel plates 53 to clamp the rod. Then, the hydraulic rod 44 drives the slide plate 41 to slide the U-shaped mounting bracket 51, thereby driving the U-shaped mounting bracket 51 to slide. The thread rolling steel plate 53 on 1 slides until the thread rolling is completed. When it is necessary to use the thread rolling rod for thread rolling, the rotary cylinder 52 is controlled to rotate the thread rolling rod 54 to face the end of the through groove. Then the rod is placed between the two thread rolling rods 54. Then the drive motor 55 is started to drive the thread rolling rod 54 to rotate and roll the thread. The thread rolling can be flexibly switched according to the specific process. During the thread rolling, the cooling mechanism 6 is used to continuously cool the thread rolling part to avoid overheating and wear of the thread rolling parts (referring to the thread rolling steel plate 53 and the thread rolling rod 54) and improve the thread rolling quality.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 5 The cooling mechanism 6 includes a support frame 61, which is fixedly installed on the fixed end plate 2. A spray pipe 62 is fixedly installed on the support frame 61. The spray pipe 62 has several spray holes and is connected to the liquid outlet of the circulation pump 8 through a conduit. The liquid inlet of the circulation pump 8 is connected to the liquid return tank 7 through a conduit.

[0032] It should be noted that when the cooling mechanism 6 is in use, the lubricating oil is introduced into the return tank 7, and then the circulation pump 8 is started to continuously introduce the lubricating oil into the spray pipe 62 through the conduit, and spray it from the spray hole of the spray pipe 62 to the thread rolling part to lubricate and cool the thread rolling part.

[0033] In this embodiment: a stepped groove is provided on the return tank 7, and a filter screen plate 71 is embedded in the stepped groove. Handles 72 are symmetrically installed at both ends of the filter screen plate 71. When the lubricating oil washes the thread rolling part, it will carry debris. The filter screen plate 71 can be used to filter the returned lubricating oil, and the handles 72 can be used to lift the filter screen plate 71 to facilitate the retrieval and recycling of the intercepted debris.

[0034] The working principle of the hardware processing thread rolling equipment provided by this utility model is as follows:

[0035] In use, according to the external thread rolling process, when it is necessary to use a rolling plate for rolling, the double-mold rolling mechanism 5 of the fixed end plate 2 and the movable end plate 4 is controlled by the CNC box 9 to rotate the rolling steel plate 53 to the end facing the through groove through the rotary cylinder 52. Then, the rod to be processed is placed between the two rolling steel plates 53. Then, the electric rod 3 drives the two rolling steel plates 53 to clamp the rod. Then, the driving hydraulic rod 44 drives the slide plate 41 to drive the U-shaped mounting frame 51 to slide, thereby driving the rolling steel plate 53 on the U-shaped mounting frame 51 to slide until the rolling is completed. When it is necessary to use a rolling rod for rolling, the rotary cylinder 52 is controlled to rotate the rolling rod 54 to the end facing the through groove. Then, the rod is placed between the two rolling rods 54. Then, the drive motor 55 is started to drive the rolling rod 54 to rotate and roll. The rolling can be flexibly switched according to the specific process.

[0036] Furthermore, during thread rolling, lubricating oil is introduced into the return tank 7, and then the circulation pump 8 is started to continuously introduce lubricating oil into the spray pipe 62 through the conduit. The lubricating oil is sprayed from the spray hole of the spray pipe 62 onto the thread rolling part to lubricate and cool the thread rolling parts, avoid overheating and wear of the thread rolling parts (referring to the thread rolling steel plate 53 and the thread rolling rod 54), and improve the thread rolling quality.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
