[0031] Referring to the drawings Figure 3 Referring to the drawings Figure 1 and the drawings Figure 5 As shown in the drawings, when the upper die 1 and the lower die 2 are closed, the positioning column 14 on the upper die 1 is connected with the guide sleeve 21 on the carrier plate 23 in a plug-in connection mode, the point pressing mechanism 3 contacts and presses the material to be processed at the corresponding position.

[0032] Specifically, the point pressing mechanism 3 comprises a pressure head 31, the pressure head is made of stainless steel and has a relatively light weight (the mass is known), a pressure sensor 36 and a counterweight part 32 are arranged at the top of the pressure head 31, the pressure head 31 is fixedly installed at the bottom of the pressure sensor 36, and the counterweight part 32 has at least one counterweight block.

[0033] As shown in the drawings Figure 3 The counterweight part 32 is supported and installed through the base 34, the pressure sensor 36 is installed at the bottom of the base 34, the pressure head 31 is installed at the bottom of the pressure sensor 36, and the pressure sensor 36 obtains the weight of the counterweight part 32 at the top and the weight of the base 34.

[0034] When the counterweight part 32 comprises a plurality of counterweight blocks, the adjacent counterweight blocks are detachably connected through the connecting piece 33, and all the counterweight blocks can be arranged and combined into any shape in any order. The weight of the pressure head 31 and all the components including the counterweight part 32 generates pressure on the material to be processed during clamping.
