[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 7 shown, an adjustable hanging head assembly includes a shank head 3, a fine-tuning sleeve 6, and a lifting core 8. The shank head 3 and the lifting core 8 are arranged in the fine-tuning sleeve 6, and the lower end of the fine-tuning sleeve 6 is connected to the upper end of the lifting core 8.

[0024] The upper end of the lifting core 8 is provided with an external thread, and the lower end of the fine-tuning sleeve 6 is provided with an internal thread. The upper end of the lifting core 8 is in threaded fit with the lower end of the fine-tuning sleeve 6. In the present invention, the surface of the lifting core 8 is an external thread of M80*3, and the lower part of the fine-tuning sleeve 6 is an internal thread of M80*3. The lifting core 8 and the fine-tuning sleeve 6 are connected by threads.

[0025] The upper end of the lifting core 8 is provided with a flat key groove 41, and the lower part of the shank head 3 is provided with a flat key 4. The flat key 4 is matched with the flat key groove 41. During operation, the flat key 4 is clamped in the flat key groove 41. When the fine-tuning sleeve 6 rotates around the shank head 3 as the axis, the lifting core 8 moves up and down relative to the shank head 3 but does not rotate.

[0026] The shank head 3 includes a central shaft 31, a disc 32 is arranged on the central shaft 31, and a groove 33 is arranged outside the disc 32; an annular groove 61 matched with the disc 32 is arranged in the fine-tuning sleeve 6, and a ball set screw 5 is arranged on the outer wall of the annular groove 61. The ball set screw 5 passes through the outer wall of the annular groove 61 and contacts the groove 33. The outer surface of the fine-tuning sleeve 6 is provided with straight knurling to increase the friction force, and a scale is marked on the upper part of the fine-tuning sleeve.

[0027] There are 60 grooves 33, and the pitch of the external thread at the upper end of the lifting core 8 and the pitch of the internal thread at the lower end of the fine-tuning sleeve 6 are both 3 mm. In the present invention, there are two ball set screws 5, and the two ball set screws 5 act on 60 grooves outside the disc 32 to ensure the granular feeling during adjustment. The pitch of the external thread at the upper end of the lifting core 8 and the pitch of the internal thread at the lower end of the fine-tuning sleeve 6 are 3 mm, that is, the adjustment height when the fine-tuning sleeve 6 rotates one circle is 3 mm. 3 mm is evenly divided into 60 equal parts by 60 grooves, and each groove corresponds to a scale line of one grid. In this way, it is ensured that the up and down adjustment distance of each grid is 3 / 60 = 0.05 mm, so as to realize the precise adjustment of the hanging head assembly.

[0028] A boss 34 is arranged on the disc 32, and a mounting hole is arranged on the boss 34. A pin 2 is arranged in cooperation with the mounting hole. When the present invention is installed on the crimping device, the pin 2 plays a role in positioning the present invention.

[0029] A fixing ring 1 is provided above the shank head 3. The fixing ring 1 is connected to the fine adjustment sleeve 6 by screws 10. The fixing ring 1 fixes the shank head 3 up and down in the fine adjustment sleeve 6 by screws, and the fine adjustment sleeve 6 can rotate with the shank head 3 as the axis.

[0030] A pressure block 9 is provided at the lower end of the lifting core 8. The pressure block 9 is connected to the lifting core 8 by bolts. A keyway 36 is provided on the shank head 3, and a flat-end set screw 7 is provided to cooperate with the keyway 36. The flat-end set screw 7 extends into the keyway 36 from the outside of the fine adjustment sleeve 6 through the keyway. The flat-end set screw 7 plays a role in limiting the up and down movement of the lifting core 8 to prevent the thread between the lifting core 8 and the shank head 3 from becoming disengaged. During use, the upper end of the mold extends into the cylindrical hole between the pressure block 9 and the lifting core 8, and the pressure block 9 is fixed to the lifting core 8 by bolts, playing a role in fixing the mold.

[0031] An adjustment method for an adjustable hanging head assembly includes the following steps: ① Install the hanging head assembly: Connect the shank head 3 to the crimping device by a pin 2, and install the mold at the lower end of the lifting core; ② Adjust the closing height of the crimping mold: Rotate the fine adjustment sleeve 6 to one side, and the lifting core 8 moves up or down; ③ As the lifting core 8 moves up or down, it drives the mold to move up or down, thereby increasing or decreasing the closing height of the crimping mold.

[0032] When adjusting the closing height of the crimping mold in step ②, rotate the fine adjustment sleeve 6, the height of the shank head 3 remains unchanged, and the flat keyway 41 of the lifting core 8 moves up and down along the flat key 4.
