Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal plate precision cutting, in particular to a fixed cutter and a fixed cutter combination used for a thin strip slitting machine to cut metal plates. Background Art
[0002] In order to operate better, the blades of the slitting machine must be properly adjusted before use. The main adjustment is the gap between the blades of the slitting machine. The shear gap between the upper and lower blades can be controlled by precision gaskets, thereby reducing shear errors and improving shear quality.
[0003] There are two main reasons for the gap between the blades of the slitting machine: first, the concentricity or balance of the blades of the slitting machine is not good, which can be improved by re-sharpening the blades to restore them to normal as soon as possible; second, the axis of the blade of the slitting machine is unbalanced, which can be re-sharpened using the sharpening device on the machine and adjusted according to the specific situation. In addition, the slitting machine is usually equipped with spacers, gaskets and other parts, which are also used to keep a certain distance between the blades and adjust the horizontal gap between the upper and lower blades. These parts are not only very strong in shape and structure, but also can effectively prevent scratches, bruises and other situations.
[0004] In short, blade adjustment is a difficult problem that requires both technology and experience. Adjusting a set of suitable cutters is a time-consuming and laborious technical and physical work. Therefore, in order to reduce the intensity and difficulty of workers' work, save working time, and improve work efficiency, it is of great significance to invent and design a fixed cutter for thin strip slitting machine to cut metal sheets. Utility Model Content
[0005] In view of the above problems, the utility model provides a fixed tool and a fixed tool combination for thin strip longitudinal shearing machines to cut metal plates, which does not require matching knives, ensures accuracy and saves time. Without changing the structure of existing equipment parts, the operator only needs to install the entire set of fixed knife groups on the existing knife shaft and lock the existing nut to perform shearing work.
[0006] To achieve the above purpose, the technical solution of the utility model is as follows:
[0007] A fixed tool for slitting metal plates on a thin strip slitting machine, comprising a knife shaft, a nut and a fixed knife group; the nut is arranged at one end of the knife shaft, and the fixed knife group is arranged on the knife shaft; the fixed knife group comprises a positioning blade, a plurality of working blades, a knife setting reference ring, a plurality of combined knife pads and a knife pressure sleeve; the knife pressure sleeve is arranged at one end of the knife shaft close to the nut; the knife setting reference ring is arranged at one end of the knife shaft away from the nut; the positioning blade is arranged next to the knife setting reference ring; the plurality of working blades are arranged between the positioning blade and the knife pressure sleeve; the plurality of combined knife pads are arranged between the plurality of working blades.
[0008] Preferably, a scrap blade is provided next to the knife pressing sleeve.
[0009] Preferably, stripping rubber rings are provided on the multiple combined knife pads.
[0010] A fixed cutter assembly for slitting metal plates by a thin strip slitting machine comprises two of the above-mentioned fixed cutters.
[0011] Preferably, the two fixed cutters are arranged one above the other.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The utility model provides a fixed tool and a fixed tool combination for thin strip slitting machine to cut metal plates, which does not require matching knives, ensures accuracy and saves time. The gap between the knives has been adjusted and repaired by professional tool personnel to ensure the accuracy of the knives. At the same time, the operator only needs to install the whole set of fixed knife groups on the existing knife shaft, which greatly saves working time and improves work efficiency. In addition, with the support of the positioning knife, the links of knife alignment and knife arrangement are reduced, the work intensity of the operator is reduced, and the difficulty of work is reduced.
