Technical Field
[0001] The present application relates to the technical field of strip steel shearing machines, and in particular to a strip steel shearing machine with adjustable shearing column numbers and a column number adjustment method. Background Art
[0002] Currently, in the steel manufacturing industry, strip slitting machines are an important part of the strip production line, and their performance directly affects the quality and production efficiency of the final product. Traditional strip slitting machines are mostly designed with a fixed number of columns, that is, once the working parameters of the slitting machine, such as blade spacing, transmission speed, etc., are determined, it is difficult to quickly adapt to the diverse changes in market demand. This causes companies to often need to shut down and replace equipment when facing orders for products of different specifications, which not only increases production costs, but also prolongs the production cycle. With the growing market demand for personalized customization of steel, how to improve the flexibility and adaptability of strip slitting machines has become one of the key challenges facing the industry; At present, some improvement measures have been proposed and applied to the actual production for the problems of strip shearing machines on the market. Among them, there are two more common solutions: The first solution is to switch between different numbers of columns by manually adjusting the position of the tool holder. Although it is simple and easy to implement, it takes a long time in actual operation and the accuracy is not easy to guarantee. Especially in the high-speed production line environment, frequent manual adjustments greatly reduce the overall production efficiency. The second solution is to use an electric or hydraulic drive system to automatically adjust the tool holder spacing; although this improves the adjustment speed and accuracy to a certain extent, the cost is relatively high and may not be the best choice for small and medium-sized enterprises. The corresponding system with a higher degree of automation is also more complicated to maintain, and higher requirements are placed on the professional skills of the operator; The above two traditional methods have their own advantages and disadvantages, but neither of them can fully meet the requirements of modern industrial production for efficiency and precision. As a result, the existing strip slitting machines are either inconvenient to adjust, seriously affecting production efficiency; or are costly and unsuitable for use by enterprises of all sizes, limiting the application and development of strip slitting machines in a wider range.
