Description of the invention (4) When there is a gap, it takes a lot of time to disassemble and install a plurality of gap maintaining elements, gap adjusting elements, cutters, pushing devices and nuts. Nuts will be in contact with adjacent space-maintaining elements. Since the friction between the nuts and the space-maintaining elements will work, a larger force is required to rotate the nuts. Recently, a small number of diverse productions have gradually increased. Due to the frequent changes in the cutting width, thickness and material of the strip plate, too much effort has been spent on the assembly and disassembly of the nut and the like, which has led to a reduction in production efficiency. (2). Second Conventional Example (Japanese Patent Application Laid-Open No. 1-1 9 9 7 1 3, International Publication No. W089 / 0 702 6) In the slitter, the first conventional example is not used. A tool holding device for holding a cutter at a predetermined position on a rotary shaft by means of a gap maintaining element, a gap adjusting element and a nut. The cutter fixing device is attached to a main body of a rotary shaft of a slitting machine, and is provided with a main body fixing mechanism for fixing the main shaft to the rotary shaft. The body fixing mechanism is a mechanism for reducing the inner diameter of the body. At the main body, a cylindrical pressure chamber is provided concentrically along its inner peripheral surface, and the pressure chamber is provided with a pressure chamber communicating with its front end. In the pressurized chamber, a pressurized piston is closed. The pressure and pressure chambers are filled with oil. On the outer peripheral surface of the body, a screw hole communicating with the pressure chamber is provided. The screw shaft is screwed into the screw hole, and then the front end of the screw shaft contacts the pressure piston of the pressure chamber. The screw shaft is screwed in, so that the pressure piston is pushed in the direction of the front end of the pressure chamber, the pressure of the pressure chamber will increase, and the thin portion between the inner surface of the pressure chamber and the inner surface of the body will Bend inside, shrink the inner diameter of the body by λ !, 〇

515733 V. Description of the invention (5) The main body is provided with a small diameter portion with a small outer diameter and a large diameter portion with a large outer diameter. The disc-shaped cutter is fitted in the small-diameter portion of the body and overlaps the end surface of the large-diameter portion. The small diameter of the body is fitted with a pushing device of the first conventional example. The pressing device is to screw in the threaded shaft exposed from its peripheral surface, and use a plurality of pressing pistons protruding from its front surface to press the tool with an equal force, and fix the tool to the end face of the large diameter part of the body. The cutter is fitted with a plurality of tool holders at the upper and lower rotating shafts. Each tool fixing device is arranged at a predetermined position of the rotation axis, and its inner diameter is reduced and fixed on the rotation axis, and the tool is fixed at the predetermined position of the rotation axis. When a cutter fixing device is used on a slitting machine, the cutter fixing device is provided with a mechanism for fixing the cutter to its body with a pressing device and then fixing the body to the rotating shaft of the slitting machine, so It takes time to disassemble and install the interval maintaining element or the nut as in the first conventional example. However, the tool holding device is not only complicated in construction and high in cost, but also the same number of tools necessary for the upper and lower rotary axes of the slitter. More expensive tool holders are required. In addition, when a plurality of tool holders are fitted and arranged on the rotating shaft of the slitter, the gap between the tools of the adjacent tool holders cannot be reduced to be smaller than the length in the axial direction of the tool holders. The strip-shaped plate is cut to a width smaller than the length in the axial direction of the tool holder. In order to reduce the cuttable width of the strip plate, when the length of the tool fixing device in the axial direction is reduced, it is difficult for the tool fixing device to maintain the same axis as the rotary axis of the slitter.

This tool pressing and fixing device fixes the rotating shaft of the cutting machine with its main body, and uses its cutting tool pressing machine to push dust evenly between the tools held between the space maintaining elements. In the radial direction of the axis of rotation. Knife — shape ΐ, unlike the object of the first known example, does not require a tool to push the gap between the clothes / nut and the nut to maintain the element toilet cap, which can eliminate the need to hold the element and the nut ... When changing the cutting tool parts of the second rotation axis: f gap between i, τ reduces the interval maintaining element and gap adjustment-in a small amount; sample =: and the time required for the assembly and disassembly of the nut. It will not cause large production efficiency. The objects of the second conventional example are different, and can be used for low competition. The shorter interval maintains the components to reduce the length of the tool. The tool is oriented to the axis of rotation of the machine. ^ Knife blades are held in the direction of the slicing official sound Λ + β +, and the strip plate can also be narrower. Visibility. The cutting line of the strip plate does not meander and straighten; the narrow-cut installation of the cutting tool and the second conventional example of the cutting tool does not cost much.

Page 10 515733 V. Description of the invention (7) The number of tools pushes the fixing device. In the conventional slitting machine, at one end of the upper and lower rotary shafts, there are small-diameter screw portions that are screwed with the nut, respectively. However, when the fixing device is pushed by the aforementioned tool, the nut and the screw portion are not required at the same time. The screw part of the rotating shaft is different from the tool fixing part of the rotating shaft, and has a thread and a small diameter. Therefore, it is impossible to fix the tool pressing and fixing device with its main body fixing mechanism. As a result, the tool cannot be arranged near the screw portion of the tool fixing portion of the rotary shaft. The configurable range of the tool will become smaller. Therefore, by using the central hole as an outer diameter expansion tube of the screw hole to screw the small diameter screw portion of the rotary shaft, the tool pressing and fixing device can be fixed to the tool fixing portion of the outer diameter and the rotary shaft by its main body fixing mechanism. Enlarge the same outer diameter.

In addition, when using a slitter, only one of the upper and lower rotary axes of the slitter is required. Don't need too much. When the tool pressing and fixing device is used in a cutting machine, the space maintaining element and the nut between the tool pressing and fixing device and the nut are not required in terms of the upper and lower rotating shafts, and the disassembly and maintenance interval can be omitted. Component and nut time. When changing the clearance between the tool position of the rotating shaft and the upper and lower tools, it can reduce the time required for disassembling and assembling the gap maintaining element and the gap adjusting element. In a small variety of production, it will not cause a significant reduction in production efficiency. For the upper and lower rotating shafts, a shorter interval in the axial center direction can be used to reduce the interval between the tools. By keeping the cutter outside the radial direction of the rotary axis of the slitter, the strip-shaped plate can also be cut with a narrower width. Its cutting line does not meander into a straight line. In addition, at one end of the rotating shaft, on a slitter having a small diameter screw portion that is screwed with a nut, a small diameter screw gear portion is screwed and fixed with the same outer diameter as the tool fixing portion. In the case of an enlarged-diameter cylinder, the aforementioned tool pressing and fixing device can be fixed to the enlarged-diameter portion by a body fixing mechanism, and the tool can be arranged near the screw portion of the tool-fixing portion of the rotating shaft. The configurable range of the tool does not become smaller.
