Embodiment 1
[0069] A kind of detachable punching upper die group of this embodiment, such as figure 1 , 6 As shown, it includes a fixedly connected upper mold base 1, an upper template 2, and a punch die embedded in the upper template 2, which passes downwards through the upper template 2, and a punching knife block 4 fixedly connected to the bottom end surface of the upper template 2 , the punch die is a detachable punch die 3, such as Figure 11 As shown, the detachable punch die 3 includes a punch base 31, a fastening mechanism 32 and a punch working end 33, such as Figure 12 As shown, the bottom of the punch base 31 is provided with a connecting head 311; as Figure 13 As shown, the fastening mechanism 32 has a sleeve-like structure, including a half-sealed connection sleeve 321 at one end and a punch hole 322 opened in the middle of the sealing end of the connection sleeve 321; The punch seat 332 and the punch end 331 connected together in an inverted "convex" shape; the upper t...
Embodiment 2
[0076] The basic steps of the assembly steps of a detachable punching upper die set in this embodiment are the same as in Embodiment 1, the difference and improvement is that in step 2, when the detachable fastening connection is made, the upper end of the punch seat 332 is pressed against When the bottom end of the connector 311 is punched, the punch end one 331 directly transmits the vertical pressure to the connector 311 through the punch seat 332, which will not affect the detachable connection between the connector sleeve 321 and the connector 311. It does not affect the convenient and easy disassembly between the connecting sleeve 321 and the connecting head 311 at any time.
Embodiment 3
[0078] A detachable punching upper die set in this embodiment has the same basic structure as that in Embodiment 1 or 2. The difference and improvement are that the connecting sleeve 321 and the connecting head 311 are threaded, and the connecting sleeve 321 is an internal thread. The connecting head 311 is an external thread; the second step is to screw the connecting sleeve 321 on the connecting head 311. Compared with detachable methods such as clamping and hinged connection, the threaded connection operation is more convenient.
