Description

Technical Field

[0001] The utility model relates to the technical field of cable shearing, in particular to a high temperature resistant cable production shearing device. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables are mainly used for multiple functions such as control installation, connecting equipment, and transmitting electricity. They are a common and indispensable material in daily life. Cables are generally composed of an outer sheath and copper wires of various specifications twisted into cables. High temperature resistant cables are cables that can transmit signals or electrical energy normally at high temperatures. A shearing device is required in the production of high temperature resistant cables to cut the cables into the required length.

[0003] For example, a cable cutting device disclosed in the utility model with authorization announcement number CN219335792U has a protective cutting block arranged on the outside of the shear knife so that the blade of the shear knife is in the shearing groove of the protective cutting block, thereby avoiding the risk of being scratched by the shear knife during manual threading. A cleaning brush plate is provided to clean the dandruff on the surface of the shear knife, and a double clamping of the cable can be achieved by providing an upper pressing block and a semicircular groove of the right-angle pressing plate.

[0004] This prior art also has the following problems when used:

[0005] The fiber brush of the device has a low hardness. After the cutting knife cuts the cable, when part of the outer sheath of the cable is embedded in the cutting knife, it is difficult for the fiber brush to brush off the outer sheath, thereby reducing the shearing effect of the shear knife on the cable. During the double compression of the cable by the device, the cable is in a stretched state. The cable turns from horizontal to vertical during the compression of the cable by the rebound sponge pad and the semicircular groove. The rebound sponge pad and the semicircular groove easily cause the cable to be subjected to greater tension, resulting in greater deformation or even breakage of the cable. Utility Model Content
