[0025] See also Figure 1-4The utility model provides a technical solution: a high-precision fastener thread rolling die, comprising a lower die 1, an upper die 2 located just above the lower die 1, and a lower rolling plate 4 located in the lower die 1, and an upper rolling plate 5 arranged above the lower rolling plate 4 and located on the lower outer side of the upper die 2, and the outer ends of the lower rolling plate 4 and the upper rolling plate 5 are fixedly installed with a mounting plate 6, the outer end of the mounting plate 6 is fixedly installed with a connecting column 7, and the upper outer side of the connecting column 7 is integrally fixedly installed with a mounting bolt 8, the outer side of the mounting bolt 8 is threadedly connected with a fixing nut 9, and the outer side of the lower end of the lower die 1 is fixedly installed with a mounting base 3;

[0026] At the same time, a second prefabricated groove 16 is opened through the interior of the mounting plate 6, and a reinforcing plate 13 is inserted into the interior of the second prefabricated groove 16. Positioning through holes 12 compatible with the connecting column 7 and the mounting bolt 8 are opened through the outer interiors of the lower mold 1 and the upper mold 2. A fixing block 10 is fixedly installed at the lower end of the inner side of the lower mold 1, and the left and right ends of the fixing block 10 are opened with a first prefabricated groove 11 compatible with the mounting plate 6. A positioning rod 14 is fixedly set at the top corner of the lower end of the upper mold 2, and a prefabricated hole 15 corresponding to and compatible with the positioning rod 14 is opened at the top corner of the lower end of the lower mold 1, which is combined to form a high-precision fastener thread rolling mold.

[0027] When using the high-precision fastener thread rolling die, the specific Figure 1 and Figure 2 As shown in, first, the whole is stably placed in the specified position through the installation base 3, and then the upper mold 2 is connected to the external stamping equipment, so that the upper mold 2 can be driven up and down by the stamping equipment. When the upper mold 2 moves downward, the positioning rod 14 can be inserted into the prefabricated hole 15, thereby realizing the positioning of the upper mold 2 and avoiding the upper mold 2 from shifting when moving. Then, the fastener required for thread rolling function is placed inside the lower mold 1 and located at the upper end of the lower rolling plate 4, and then the stamping equipment is started to make the upper mold 2 move downward under the action of the stamping equipment. At this time, the upper rolling plate 5 can contact the upper end of the fastener, so that the fastener can be tightly fitted with the lower rolling plate 4 and the upper rolling plate 5 respectively, and then the fastener can be rolled under the action of the stamping equipment.

[0028] Specific as Figure 1 , Figure 3 and Figure 4As shown in , since the connecting column 7 and the mounting bolt 8 are connected to the lower mold 1 by plugging through the positioning through hole 12, and the fixing nuts 9 are respectively located at the lower outer ends of the lower mold 1 and the upper mold 2, when it is necessary to disassemble the lower rubbing plate 4, the fixing nut 9 located at the outer side of the bottom of the lower mold 1 can be rotated, so that the fixing nut 9 loses its fixing effect on the mounting bolt 8 and separates, and then the reinforcing plates 13 are pulled out of the front and rear ends respectively, so that the reinforcing plates 13 are separated from the second prefabricated groove 16, and then the lower rubbing plate 4 is pulled out upward, so that the lower rubbing plate 4 can drive the mounting plate 6, the connecting column 7 and the mounting bolt 8 to move upward, and the connecting column 7 and the mounting bolt 8 are separated from the positioning through hole 12, and the mounting plate 6 is separated from the first prefabricated groove 11, so as to facilitate the disassembly of the lower rubbing plate 4. Similarly, the upper rubbing plate 5 can be removed from the bottom of the upper mold 2, so as to facilitate the disassembly of the upper rubbing plate 5 and facilitate subsequent replacement;

[0029] Combination Figure 1 and Figure 2 As shown in the figure, when the upper thread rolling plate 5 is fixedly installed by the mounting bolt 8 and the mounting plate 6, the reinforcing plate 13 can be inserted into the mounting plate 6 from the outside to the inside. At this time, the reinforcing plate 13 and the second prefabricated groove 16 have a good reinforcement effect on the mounting plate 6, avoiding a certain degree of damage to the upper thread rolling plate 5 during the stamping work. Similarly, the reinforcing plate 13 can be inserted into the lower mold 1 to reinforce the lower thread rolling plate 4. This is the method of using the high-precision fastener thread rolling mold.
