Technical Field

[0001] The utility model relates to the technical field of thread rolling processing, in particular to an ultra-long rod thread rolling seat tooling. Background Art

[0002] At present, thread rolling machines are used in the production of standard and non-standard parts such as screws, bolts, and screws.

[0003] The main structure of the existing thread rolling machine includes a machine body, a pair of thread rolling shafts, a pair of thread rolling discs driven by the thread rolling shafts, and a thread rolling disc seat for positioning the thread rolling discs on the machine body. The thread rolling die is installed on the thread rolling disc seat for processing.

[0004] During the actual processing, when the rod is ground between the two rolling discs, the rolling discs will generate tangential force on the rod, and the directions of the tangential forces of the two rolling discs are different. Therefore, the entire rolling disc seat supporting the rod will often vibrate under the action of the two tangential forces. Especially when processing extra-long rods (length exceeding 500mm), the vibration of the rod will be aggravated, thereby affecting the accuracy of thread processing. Utility Model Content

[0005] In view of this, the utility model provides an extra-long rod thread rolling seat tooling to solve the problem that when a thread rolling machine processes an extra-long rod, the vibration of the rod is aggravated, thereby affecting the thread processing accuracy.

[0006] The utility model provides an extra-long rod thread rolling seat tooling, comprising:

[0007] The first platform is located next to the thread rolling machine;

[0013] Optionally, the extra-long rod thread rolling seat tooling also includes a third platform, which is located directly below the first platform. A jacking device is fixed on the third platform, and the top of the jacking device is connected to the first platform. The jacking device is used to adjust the height of the first platform.

[0014] Optionally, a vertical guide rod is further provided between the first platform and the third platform, and a through hole cooperating with the guide rod is provided on the first platform and / or the third platform.

[0015] Optionally, the guide rod is a threaded rod, and a locking nut is connected to the guide rod.

[0016] Optionally, the lifting device is a jack, and the top of the lifting device is connected to the center of the lower surface of the first platform; there are multiple guide rods, and all of the guide rods are evenly distributed around the lifting device.
