Description

A manual cable stripper

technical field

The utility model relates to a manual cable stripper, which belongs to the technical field of electric power, communication engineering and maintenance tools.

Background technique

The manual cable stripper is mainly used for stripping the main insulation layer and outer semiconducting layer of various high-voltage cables for power and communication. After investigation, similar products at home and abroad have brackets and tool holders with low strength, poor toughness, easy deformation, and heavy quality. The thread pitch of the screw rod and the bushing is large, the machining accuracy is low, the clamping force on the cable is not suitable, and the outer main insulation layer of the cable is damaged. The adjustment accuracy of the cutter is low, the adjustment is inflexible, and the cutting angle is not suitable, which makes the end surface of the main insulating layer uneven, easily cuts the outer layer of the cable core wire or makes the main insulating layer impenetrable. The surface roughness of the roller is poor, and the handle is easy to rotate during work, so that the roller cannot be optimally balanced, and the outer surface of the main insulation layer of the cable is severely rubbed and squeezed, causing the outer surface to be damaged. There are many types of specifications, small working range, and large volume. During assembly and maintenance, it is necessary to carry strippers of various specifications to complete the task, which brings the staff the same tools.

The domestic patent document "Multifunctional High-voltage Cable Stripping Knife" (publication number 103247979A) discloses a multi-functional high-voltage cable stripping knife that can not only peel and cut the outer insulation of high-voltage cables, but also cut the armor layer of high-voltage cables, including brackets. The upper support plate and the lower support plate are designed with a right support plate between the right ends of the upper support plate and the lower support plate. There is a threaded hole on the upper support plate, and the internal thread of the threaded hole is connected with an adjusting threaded rod, and the upper end of the adjusting threaded rod is fixed. The upper handle is connected, and the lower end of the adjusting threaded rod is connected with the knife rest. The right side of the knife rest is designed with a slide rail groove, and the left side of the right support plate is designed with a slide rail. The slide rail groove is matched with the slide rail, and the lower support plate is connected There are rollers, and the lower surface of the lower support plate is fixedly connected with the lower handle. This comparison document cannot peel off the polyethylene main insulation layer and outer skin of the cable at one time. First install a paper cutter to peel off the outer skin, and then replace the saw blade to peel off the main insulation layer. It is easy to cut the outer layer of the cable core wire or make the main insulation layer It cannot be cut through, and the tool needs to be replaced at the same time, so the operation is complicated.
