Blade used for slitting steel strips or aluminum strips

Abstract

The invention belongs to the technical field of optical cable materials and tools, and particularly relates to a blade used for slitting steel strips and aluminum strips. The blade is provided with ablade body and is characterized in that the blade body is in a circular truncated cone cylindrical shape; a concave mounting groove is formed in the blade body from the bottom face with a large area to the bottom face with a small area; the mounting groove does not penetrate through the bottom face with the small area of the blade body; the mounting groove is provided with a plurality of fixing grooves penetrating through from the surface of the mounting groove to the bottom face with the small area of the blade body; a cylindrical transition body is arranged on the bottom face with the smallarea of the blade body in an outward protruding mode; the diameter of the transition body is smaller than that of the bottom face with the small area of the blade body; the blade is provided with a mounting hole penetrating through the transition body from the surface of the mounting groove; and the blade is formed integrally. The blade has the main beneficial technical effects that the cutting speed is high, abrasion resistance is achieved, replacement is convenient, cost is low, the blade can be used for a long time, and a cutting face is smooth and flat.

Description

[0001] This application is a divisional application of an invention patent application titled: A blade for cutting steel or aluminum strips, with an application date of December 15, 2016, and an application number of: 2016111580480. technical field [0002] The invention belongs to the technical field of optical cable materials and tools, and in particular relates to a blade for cutting steel strips or aluminum strips. Background technique [0003] Steel strips or aluminum strips are used as raw and auxiliary materials commonly used in the technical field of electric wires and cables, and their usage is increasing day by day. Generally, there are two main methods for the application of steel strip or aluminum strip in cables: one is longitudinal wrapping, that is, the edges of steel strip or aluminum strip are folded in half or folded in half at a certain position. This method is called longitudinal wrapping. ; The second is spiral cladding, that is, the steel strip or alumi...

Problems solved by technology

In order to save costs and reduce inventory, manufacturing companies usually do not keep a lot of inventory; on the other hand, the time from order to delivery for cable manufacturers is getting shorter and shorter. In this case, steel strip or aluminum strip manufacturers are required to produce It can quickly provide multiple steel strips or aluminum strips that meet the requirements. In the prior art, steel knives are usually used to cut the steel strips or aluminum strips, and the knives used are not durable. Therefore, the steel strips or aluminum strips are seriously affected. belt delivery speed
