Description

Technical Field

[0001] The utility model relates to the technical field of automated production equipment, in particular to a full-automatic cutting machine for terminal blocks. Background Art

[0002] Terminal block means an insulating component that carries multiple or multiple groups of mutually insulated terminal components and is used to fix the supporting parts. The function of the terminal block is to connect the lines of the devices inside the screen and the devices outside the screen, and play the role of signal (current and voltage) transmission. With the terminal block, the wiring is beautiful and easy to maintain. When connecting long-distance lines, it is mainly reliable, and the construction and maintenance are convenient. During the production process of the injection mold, the gate and the product are connected together after the mold is opened and taken out. At present, the number of segments of the common terminal blocks on the market is 12 segments. The number of segments required after cutting varies from 1 segment, 2 segments, 3 segments, 4 segments, 5 segments, and 6 segments. After the terminal blocks are cooled to a certain extent, they are manually cut into segments according to the required length of the terminal blocks through a fixture with a cutter. However, this operation method is inefficient and labor-intensive for workers. Therefore, semi-automatic cutting machines are available on the market, but they do not have the function of loading and unloading, and require manual loading and unloading.
