Tool for stripping and cutting grooves of cable insulation layer

Abstract

The invention discloses a stripping, cutting and grooving tool for cable insulation layer, which comprises: a tool rest mechanism, used for installing a knife or a blade; a cutter, which includes a first knife handle and a cutting part, and the knife is installed on the knife rest mechanism To strip and cut the cable, the main deflection angle of the cutting part is 20°~25°, the secondary deflection angle is 2°~5°, and the rake angle is 20°~30°; the blade includes the second handle and Knife head, mount the blade to the knife holder mechanism to slot the cable. Its advantages are: the cost of this device is close to domestic products, but its use effect is equivalent to that of imported products, and it also has the slotting function that domestic products do not have; this device is suitable for cables of various specifications and is conducive to mass production, which can meet Instant supply needs.

Description

technical field [0001] The invention relates to the field of stripping and cutting tooling, in particular to a stripping, cutting and slotting tool for cable insulation layers. Background technique [0002] In the on-site construction of the cable system, the outermost layer of the outer insulation part of the cable should be cut with a cutting device to achieve the effect of easy assembly, but the following problems will occur: [0003] 1. First of all, the finish is not good enough, and it often takes a lot of manpower to polish and polish on-site after cutting. On the one hand, it affects the progress of the project and the efficiency is not high enough. On the other hand, it brings hidden dangers to the assembly quality; [0004] 2. Secondly, the life of the tool is not good enough, and the waste is serious. Generally, the tool wears very badly after cutting about 100 meters. On the one hand, there is no tool repair equipment, and on the other hand, tool repair requires...

Problems solved by technology

[0003] 1. First of all, the finish is not good enough, and it often takes a lot of manpower to polish and polish on-site after cutting. On the one hand, it affects the progress of the project and the efficiency is not high enough. On the other hand, it brings hidden dangers to the assembly quality;

[0004] 2. Secondly, the life of the tool is not good enough, and the waste is serious

Generally, the wear of the tool is very serious after cutting about 100 meters. On the one hand, there is no repair equipment for the tool, and on the other hand, the repair of the tool requires considerable experience and skills, which cannot be implemented on site, so the tool life is often not long.

[0005] 3. Finally, the whole set of equipment is not economical. At present, the equipment that can solve the above two problems are all imported products, the value of which is tens of thousands of yuan, which is quite expensive and the cost input is relatively high.

[0006] At present, the cable insulation stripping, cutting and grooving knives used in the training center of the power company are all imported products. The repair has led to a serious waste of resources; although there are cable insulation stripping cutters sold in the domestic market, they can only strip and cut the outer shielding and insulation, and cannot slot. Moreover, the width of the knife holder of domestic products is small, and the contact width with the cable is narrow. When cutting the insulation layer, the automatic centering ability is poor, the operation is inconvenient, and the stripping effect is not good; in addition, the knife holder has low strength and is easy to deform, which affects the use effect
