Description

Technical Field

[0001] The utility model relates to the technical field of rolling, in particular to a rolling die for a numerically controlled lathe. Background Art

[0002] In the production process of automotive engine oil plugs, thread rolling dies are needed to roll threads on the surface of the workpiece. Thread rolling dies are special tools used to roll threads on workpieces. It uses the principle of plastic deformation to form the desired thread shape by the relative movement between the rolling die and the workpiece to cause plastic deformation on the surface of the workpiece. The thread rolling die usually consists of rollers, templates, and pressure blocks. The roller is the core component of the rolling die, and its surface has the same tooth shape and pitch as the processed thread. During the rolling process, the workpiece and the thread rolling die need to be installed on the CNC lathe, and then processed by the CNC lathe. At this time, the roller transfers the thread shape to the workpiece through a certain pressure and rotation. The template and pressure block are used to fix the workpiece to ensure stability and accuracy during the rolling process. Thread rolling dies are suitable for mass production of external threads of standard fasteners and other threaded connectors. It has high processing efficiency, high precision, good surface quality, and can save materials. In the existing patent application with application number CN202220448300.6, an external thread rolling tool is proposed. However, due to the lack of a structure for cleaning the thread rolling mechanism, when debris and large particles of dust are attached to the thread rolling mechanism, the surface of the workpiece is easily crushed, which will reduce the quality of the processed workpiece. Therefore, it needs to be improved. Utility Model Content

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, four mounting brackets 3 are symmetrically fixedly installed at the upper and lower ends of the roller mounting frame 1, and the mounting brackets 3 are composed of a mounting frame 6 and a mounting guide rod 7. The mounting guide rod 7 is longitudinally installed in the mounting frame 6, and a limiting structure 4 is sleeved on the mounting guide rod 7. The limiting structure 4 is composed of a movable mounting block 8 and a limiting spring 11. The limiting spring 11 is fixedly installed on the upper end of the movable mounting block 8. A cleaning structure 5 is rotatably installed on the two movable mounting blocks 8 on the two adjacent limiting structures 4. The cleaning structure 5 is composed of a rolling roller 12, a mounting shaft 13 and a soft adhesive sleeve 14. There are two mounting shafts 13 that are symmetrically fixedly installed at both ends of the rolling roller 12. The soft adhesive sleeve 14 is fixedly sleeved on the rolling roller 12, and the soft adhesive sleeve 14 can contact the rolling roller 2. The mounting frame 6 on the mounting bracket 3 is fixedly connected to the roller mounting frame 1, and the mounting guide rod 7 is connected to the mounting frame 6. For fixed connection, a blind hole 9 is provided at the inner end of the movable mounting block 8 on the limiting structure 4, and a mounting hole 10 is provided on the movable mounting block 8 and on the outer side of the blind hole 9. The mounting hole 10 passes through the movable mounting block 8 up and down, and the movable mounting block 8 is slidably sleeved on the mounting guide rod 7 up and down through the mounting hole 10 provided thereon, and the limiting spring 11 is also sleeved on the mounting guide rod 7. The rolling roller 12 on the cleaning structure 5 is located between the two movable mounting blocks 8, and the mounting shaft 13 is rotatably installed in the blind hole 9 provided at the inner end of the movable mounting block 8. By arranging a mounting bracket 3 on the roller mounting frame 1, arranging a limiting structure 4 on the mounting bracket 3, and arranging a cleaning structure 5 on the limiting structure 4, so that they cooperate with each other, the rolling roller 2 can be cleaned, thereby removing dust and debris attached to the surface of the rolling roller 2, thereby reducing the probability of the workpiece surface being crushed, and ultimately improving the quality of the processed workpiece.

[0021] It should be noted that the utility model is a rolling mold for a CNC lathe. When in use, under the elastic force of the limit spring 11, the movable mounting block 8 will move the cleaning structure 5 toward the rolling roller 2, so that the cleaning structure 5 is pressed on the rolling roller 2. When the rolling roller 2 rotates, the cleaning structure 5 will produce friction rotation with the rolling roller 2, and then the soft sticky sleeve 14 on the cleaning structure 5 will clean up the dust and debris attached to the rolling roller 2. Finally, when the rolling roller 2 with a relatively clean surface rolls the thread on the workpiece, it is not easy to damage the surface of the workpiece, so that the quality of the processed workpiece can be better.
