JPH01271112A - Burr-free continuous cutting machine - Google Patents

Abstract

PURPOSE:To permit the cut of a plate as it is passed continuously in a burr-free state by realizing highly precise control in a slitting direction in order to cause a reversing shear due to a roll's pressing and sandwiching after the plate is kept half-cut. CONSTITUTION:Along a rail 2 installed on a support 1, the bed 4 of a cutting machine cabinet is moved via a screw shaft 15 and a nut 16 in the same flowing speed as that of a plate 23. While the bed 4 runs at the same speed as that of the plate 23, a motor 19 is driven to move slide bases 7, 8 along rails 5, 6 via a screw shaft 17 and a line shaft 18 for making a half-cut of the plate 23 by a upside cutter 10 and a downside cutter 9, then the half-cut plate 23 is given a reversing shear pressed against by separating rolls 13, 14 to be separated, resulting in the termination of the cut. After the cut, the bed 4 of the cutting machine cabinet is rapidly returned along the rail 2, then put in the next cutting process.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a cutting machine for metal plates or coils. More specifically, when cutting a metal plate, etc., burrs or burrs occur on the cut surface, and if the cut surface is used as a product as is,
In addition, since there are problems such as the possibility of binding during handling, the present invention relates to a cutting machine that uses a two-step double-cutting method in which a metal plate or the like is first cut in half and then separated by reverse cutting.

<Conventional technology> Conventionally, shearing was performed with upper and lower round blades, a combination of a round blade and a straight blade, or a combination of a straight blade and a straight blade, and cutting was performed at -degrees, resulting in burrs or burrs on the cut surface. A problem had occurred.

<Sequence of tasks to be solved by the invention> Conventionally, the upper and lower cutters were used to cut at the same time, which resulted in burrs or burrs, but by controlling the depth of cut into the material to be cut, it is possible to cut the material in half in the first step. After that, in the second step, the cutting work is completed by pressing with rolls (1) and separating by creating a reverse slit.The roll slitting method, which has been put into practical use in recent years, is applied to shirring. By doing so, the present invention aims to provide a cutting device that eliminates the occurrence of burrs or burrs at the cutting portion.

<Means for solving the problem> A metal plate is cut in half, then pressed and clamped by rolls, and a blade head that can be controlled with high precision in the depth of cut direction is installed to create reverse viscous cutting. This method eliminates burrs or burrs by cutting in half while controlling the amount, and then sandwiching and separating with rolls. The cutting method is a continuous plate feed cutting method that cuts the plate while passing it through the plate continuously. Examples will be described below with reference to the drawings.

<Example> A rail 2 is provided on a machine base 1, and a frame bed 4 is provided on the rail via a slide bearing. frame bet 4
A lower cutter 9 and a lower rail 5 are provided on the lower side, and an upper rail 6 is provided on the upper side.

A slide base 7 to which a lower separation roll 11, 13 is fixed is slidably installed on the lower rail 5 on the lower side, and the upper rail 6
A slide base 8 to which separation rolls 12 and 14 and an upper cutter 10 are fixed is slidably suspended. A drive source 22 is provided to move the cutting machine main body at the same speed as the flow of the cutting plate 23, and a reduction gear 21. Fix the screw shaft 15 and nut 16. In addition, the present invention has a configuration in which the power of the drive motor 19 is transmitted to the slide bases 7 and 8 via the reduction gear 20% threaded shaft 17 and line shaft 18 for cutting.

Function> When cutting, the cutting machine body is first moved in the Y1 direction and then moved in the Y direction at the same speed as the flow of the plate 23. While the cutting machine body is moving with the board in the Y direction, the motor 19 is turned on inside the cutting machine body to move the slide base 7.8 in the two directions of the arrows, and the upper cutter 10 and the lower cutter 9 are moved. The half-cut board is cut in half by the rear separation rolls 13 and 14, and the half-cut board is pressed and separated by cutting and the cutting is completed. After cutting is completed, the cutting machine body is quickly returned to the Y direction, and then the next cutting process begins. .

<Effects of the Invention> This is a useful invention because it is possible to continuously cut the board without burrs while passing the sheet through it, resulting in a cut surface without burrs or burrs compared to conventional shears.
