Description

TECHNICAL FIELD

[0001] The utility model belongs to the steel smelting related technical field, especially a kind of core-spun yarn cutting device. BACKGROUND

[0002] Core-spun yarn is made of alloy powder wrapped by steel band. According to different alloy powder, it can be divided into: silicon calcium core-spun wire, silicon manganese calcium wire, silicon calcium barium wire, barium aluminum wire, aluminum calcium wire, calcium iron wire, pure calcium wire and so on. The winding appearance is similar to coil. Core-spun wire can more effectively add smelting material to molten steel or molten iron in the process of steelmaking or casting. When the skin of core-spun wire dissolves, the core can be fully dissolved and chemically reacted in the ideal position, effectively avoiding the reaction with air and slag, improving the absorption rate of smelting material, changing the shape of molten steel inclusions and effectively improving the quality of steelmaking and casting products. Usually, before feeding into molten steel, the corresponding length of core-spun wire is selected according to the quality or volume of molten steel, that is, the feeding amount of core-spun wire needs to match the quality of molten steel, and cannot be too much or too little. However, core-spun wire is usually packed in coils, which needs to be cut according to actual needs, but there are still the following problems in actual cutting operation:

[0003] Because core-spun wire is made of alloy powder wrapped by steel band, the overall strength and hardness are large, so it cannot be simply cut off, so it needs to be cut by corresponding equipment (such as abrasive wheel cutting, hydraulic cutting). This cutting method is similar to cutting steel plate and reinforcing steel, but core-spun wire is different from such materials, which contains corresponding alloy powder. If the abrasive wheel cutting is driven by motor, it may cause a large amount of alloy powder leakage, resulting in unqualified quality ratio. If it is hydraulic cutting, expensive and large cutting equipment is needed, which is very inconvenient.

[0004] Secondly, when rotating cutting, sparks may be produced by splashing out of waste, which affects the surrounding environment and needs to be improved. UTILITY MODEL CONTENTS

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figures 1-6 As shown, this utility model is a cored wire cutting device, including an upper arc plate 1, a lower arc plate 2, a base 3, a motor 4, and a ball bearing 5. The upper arc plate 1 and the lower arc plate 2 are symmetrically distributed, and upper ear plates 101 are fixed on both sides of the upper arc plate 1, and lower ear plates 201 are fixed on both sides of the lower arc plate 2. Two symmetrical connecting screws 202 are fixed at the upper end of each lower ear plate 201. The upper part of the connecting screw 202 passes through the upper ear plate 101 and extends out, and the part of the connecting screw 202 above the upper ear plate 101 is threaded with a wing nut 2021.

[0030] Before cutting the cored wire, align the cutting blade 401 above the position to be cut, then cover the outside of the cored wire with the upper arc plate 1 and the lower arc plate 2, and at the same time, let the connecting screw 202 on the lower ear plate 201 pass through the upper ear plate 101 and then extend out, and then screw on the wing nut 2021 to lock it to a certain extent. It is suitable for cored wires of various diameters within a certain range, which facilitates subsequent cutting and slitting processes.

[0031] The base 3 is located above the upper arc plate 1, the upper arc plate 1 is located above the lower arc plate 2, the base 3 is fixed with a motor 4, and the output shaft of the motor 4 is fixed with a cutting blade 401.

[0032] Three adjusting screws 102 arranged in an isosceles triangle are fixed on the outer arc surface of the upper arc plate 1, and the upper part of the adjusting screws 102 passes through the base 3 and extends out; the bottom surface of the base 3 is an arc surface, and a spring 103 is sleeved on the adjusting screws 102 below the base 3, and the upper and lower ends of the spring 103 are fixed to the bottom surface of the base 3 and the outer arc surface of the upper arc plate 1, respectively.

[0033] The portion of the adjusting screw 102 located above the base 3 is externally threaded with an adjusting nut 1021;

[0034] During the cutting operation, the motor 4 drives the cutting blade 401 to rotate. Then, the motor 4 and the base 3 are pressed down and the spring 103 is compressed until the thickness of the steel strip is sufficient to cut through it. Then, the adjusting nut 1021 is rotated to limit the cutting depth without pressing the base 3 down again. Only the outer layer of steel strip needs to be cut, without cutting the inner alloy powder. Then, the upper arc plate 1 and the lower arc plate 2 are rotated outside the core wire, so that the cutting blade 401 performs a circular cut around the outer circumference of the steel strip. The steel strip breaks, and the alloy powder is not lost in excess, thus completing the cutting process.

[0035] Three rows of equally spaced balls 5 are embedded in the inner arc surfaces of both the upper arc plate 1 and the lower arc plate 2.

[0036] The ball bearing 5 can be replaced with a roller structure that can only move in one direction. The roller is designed so that after the upper arc plate 1 and the lower arc plate 2 clamp the core wire, they can also move in a circle outside the core wire to assist in the circumferential cutting process.

[0037] A protective plate 301 is fixed on the end of the base 3 near the output shaft of the motor 4, and a protective frame 302 is fixed on the side of the protective plate 301 away from the base 3. The bottom ends of the protective plate 301 and the protective frame 302 are magnetically connected to a U-shaped frame 303. The cutting blade 401 is located in the inner cavity of the protective frame 302, and the output shaft of the motor 4 passes through the protective plate 301. Both the protective frame 302 and the U-shaped frame 303 are provided with cavities. The inner radius of the protective frame 302 is larger than the rotation radius of the cutting blade 401.

[0038] During the entire cutting process, the generated waste chips and sparks will travel in a circle as the cutting blade 401 rotates. The protective frame 302 and U-shaped frame 303 outside the cutting blade 401 can block the waste chips and sparks generated during cutting within the protective frame 302 and U-shaped frame 303, thereby preventing them from affecting the outside world.

[0039] The specific working principle of this utility model is as follows: First, before cutting the cored wire, the cutting blade 401 is aligned above the position to be cut. Then, the upper arc plate 1 and the lower arc plate 2 are wrapped around the outside of the cored wire. At the same time, the connecting screw 202 on the lower ear plate 201 is inserted into the upper ear plate 101 and then extends out. Then, the wing nut 2021 is screwed on for a certain degree of locking. Subsequently, the cutting operation is carried out. The pressing motor 4 and the base 3 are moved down, and the spring 103 is compressed until it is thick enough to cut the steel strip. After rotating the adjusting nut 1021 to the limit, there is no need to press down the base 3 again. Then, the upper arc plate 1 and the lower arc plate 2 are rotated outside the core wire. The roller setting allows the upper arc plate 1 and the lower arc plate 2 to perform circumferential motion outside the core wire after clamping it. This allows the cutting blade 401 to perform circumferential cutting around the outer circumference of the steel strip. The cutting stops after the steel strip is completely broken, and the alloy powder will not be lost excessively, thus completing the cutting process. The waste and sparks generated during cutting will be blocked in the protective frame 302 and the U-shaped frame 303.

[0040] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
