Embodiment Construction

[0019] like figure 1 and figure 2 As shown, a plate connection mold for fences according to the present invention includes an upper mold, a lower mold, and a punch arranged at the lower end of the upper mold.

[0020] Wherein, the upper end of the lower mold is provided with a vacancy for cooperating with the punch.

[0021] Plates that need to be connected to each other are arranged between the punch and the space.

[0022] The board is 2 layers.

[0023] The punch is made of a material with a hardness higher than that of the space, so as to avoid damage to the punch when used.

[0024] The punch is a cylindrical punch.

[0025] The bottom edge of the space has chamfers or rounded chamfers, so that it is easier to feed into it and realize the riveting between the plates.

[0026] The junction between the punch and the die is chamfered or rounded.

[0027] The inner wall of the vacancy is provided with a protective member having the same size and shape as the vacancy, a...

Description

technical field [0001] The invention relates to a mold, in particular to a plate connecting mold used on a fence. Background technique [0002] People often need to connect the plates. The general riveting is relatively expensive due to the complexity of the riveting mold, and the riveting effect is relatively general. [0003] Therefore, it is necessary to carry out technical improvement to the existing riveting die. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a board connection die for fences with the advantages of simple structure, long service life of the die, simple riveting process, low cost, and good fixed connection effect. [0005] The present invention is achieved through the following technical proposals: a plate connecting die for fences, comprising an upper die, a lower die, and a punch arranged at the lower end of the upper die. [0006] As a preferred technical solution, the upper end of the ...
