Description

Technical Field

[0002] Ultra-high-strength steel is a type of alloy steel used to manufacture structural parts that withstand higher stresses. This type of steel generally has sufficient toughness and high specific strength and yield ratio, as well as good weldability and formability. According to the degree of alloying and microstructure, it can be divided into three categories: low-alloy, medium-alloy and high-alloy ultra-high-strength steel. Ultra-high-strength steel is formed into profiles after plastic processing. Profiles are solid straight bars with a certain cross-sectional shape and size. Profiles can be used alone or further processed into other manufactured products. For example, they can be used after uniform cutting using a tracking cutting machine. They are often used in building structures and manufacturing and installation.

[0031] In the specific implementation process, Figures 1 to 8 As shown, it includes a strong steel body 3, a cutting machine body 1 for cutting the strong steel body 3, a limiting assembly for clamping and correcting the outside of the strong steel body 3, and a blanking assembly for intermittent rotary feeding. The inner wall of the cutting machine body 1 is provided with a strong steel body 3, and a blanking assembly is provided on one side of the cutting machine body 1. The input end of the blanking assembly is located at the discharge output end of the cutting machine body 1, and the outer surface of the blanking assembly matches the size of the inner wall of the strong steel body 3. The output end of the cutting machine body 1 is provided with a cutting blade 2, and the two ends of the cutting blade 2 are respectively fixedly connected to the inner wall of the limiting assembly, and the size of the inner wall of the limiting assembly matches the outer wall of the strong steel body 3. By arranging limiting assemblies on both sides of the cutting blade 2, when the cutting machine body 1 drives the cutting blade 2 to move, the limiting assembly is synchronously transmitted with the cutting blade 2, which can avoid errors and has good reliability.

[0032] The limiting assembly includes a first bracket 4, a second bracket 5, a limiting outer frame 6 and a pushing bracket. The inner side walls of the pushing bracket are fixedly connected to the two ends of the cutting blade 2. The first bracket 4, the second bracket 5 and the limiting outer frame 6 are respectively arranged on both sides of the output end of the cutting machine body 1. The limiting outer frame 6 is arranged in a "V" shape. The first bracket 4 and the second bracket 5 are respectively located at both ends of the limiting outer frame 6. The two sides of the bottom of the pushing bracket are respectively fitted with the opposite ends of the first bracket 4 and the second bracket 5. The pushing bracket includes a connecting bracket 7 and a limiting head 8. The inner wall of the connecting bracket 7 The side walls are fixedly connected to the two ends of the cutting blade 2 respectively, the bottom of the connecting bracket 7 is fixedly connected to the top of the limit head 8, the two sides of the limit head 8 are fitted with the first bracket 4 and the second bracket 5 opposite end, and the two sides of the limit head 8 are matched with the side wall sizes of the first bracket 4 and the second bracket 5 opposite end, and the two ends of one side of the limit outer frame 6 are respectively provided with elastic members 22 between the bottom walls of the first bracket 4 and the second bracket 5; through the arrangement of the first bracket 4, the second bracket 5 and the limit outer frame 6, the cutting blade 2 can cut the strong steel body 3 when it moves obliquely , the connecting brackets 7 on both sides of the cutting blade 2 will move relative to each other. When the cutting blade 2 is at the top, the top of the limiting outer frame 6 is in contact with the strong steel body 3, and the bottom sides of the limiting head 8 are in contact with the first bracket 4 and the second bracket 5. When the cutting blade 2 gradually cuts the strong steel body 3 obliquely, the two ends of the cut surface of the strong steel body 3 will be deformed. At this time, the bottom wall of the limiting head 8 gradually fits with the first bracket 4 and the second bracket 5, causing the first bracket 4 and the second bracket 5 to move downward and gradually fit with the two ends of the limiting outer frame 6 set in a "V" shape.

Finally, when the cutting blade 2 reaches the bottom, the first bracket 4 and the second bracket 5 are completely closed with the limiting outer frame 6 and the strong steel body 3 is corrected. The limiting components respectively arranged on both sides of the cutting blade 2 can simultaneously correct one end of the strong steel body 3 being cut and one end of the strong steel body 3 of the next feeding, so that the strong steel body 3 can be corrected at both ends after being cut by the cutting machine body 1, thereby achieving the purpose of high precision on both sides of the strong steel body 3 and reducing subsequent processing;

[0033] The top of both ends of one side of the limiting external frame 6 is respectively provided with a hinged bracket 9 and the bottom wall of the first bracket 4 and the second bracket 5. The inner side walls of the hinged bracket 9 at the upper and lower ends are respectively connected to the two ends of the elastic member 22. Through the setting of the hinged bracket 9, when the first bracket 4 and the second bracket 5 expand with the elastic member 22, the spring can expand according to the rotation of the hinged bracket 9, thereby reducing the bending of the spring, thereby affecting the normal operation of the subsequent cutting machine body 1.

[0034] The blanking assembly includes a fixed bracket 10, four positioning brackets 12, a driven bracket and a driving member. One end of the top of the fixed bracket 10 is connected to the fixed end of the driving member. A driven long rod 11 is passed through the top of one end of the fixed bracket 10. A driven bracket is arranged around the end of the driven long rod 11 away from the fixed bracket 10. One end of the driven bracket is located at the discharge output end of the cutting machine body 1, and the outer surface of the driven bracket matches the size of the inner wall of the strong steel body 3. The four positioning brackets 12 are circumferentially equidistantly arranged on the outer surface of the driven long rod 11. A limiting long groove 14 is formed between the four positioning brackets 12. The outer surfaces of the four positioning brackets 12 are respectively fitted with the outer surface of one end of the driving member. Two toggle cylinders 21 are equidistantly provided at one end of the driving member. The size of the toggle cylinder 21 matches the size of the limiting long groove 14 formed between the four positioning brackets 12. The driven bracket includes four limiting ring plates 15 and four limiting pillars 16. The four limiting ring plates 1 5 and four limiting pillars 16 are arranged in a cross on the outer surface of the driven long rod 11, and the limiting pillar 16 is located at the center of the limiting ring plate 15. The outer wall of the limiting pillar 16 matches the size of the inner wall of the strong steel body 3. The driving part includes an active disc and a driving motor 20 for driving. The bottom of the driving motor 20 is fixedly connected to one end of the top of the fixed bracket 10. The output end of the driving motor 20 is fixedly connected to the center of one side of the active disc through a shaft. The end of the active disc away from the driving motor 20 is fixedly connected to the two toggle cylinders 21. The active disc includes a coaxially arranged outer disc 17 and an inner disc 18. One end of the outer disc 17 is fixedly connected to the two toggle cylinders 21, and the two toggle cylinders 21 are located at the upper and lower ends of the inner disc 18. A crescent groove 19 is respectively opened at both ends of the inner disc 18. The tops of the four positioning brackets 12 are respectively provided with an arc groove 13 that matches the size of the outer wall of the inner disc 18;By starting the driving member, the driving member drives the coaxially arranged outer disc 17 and the inner disc 18 through the shaft, so that the two toggle cylinders 21 on the outer disc 17 rotate, thereby driving the four positioning brackets 12 that fit with the inner disc 18. The toggle cylinder 21 gradually contacts the limiting long groove 14 formed by the four positioning brackets 12 after rotation, so that the four positioning brackets 12 are driven by the toggle cylinder 21 to form an intermittent movement of the positioning bracket 12. At this time, the positioning bracket 12 will pass through the crescent groove 19 on the inner disc 18 to prevent the positioning bracket 12 from getting stuck, and when the toggle cylinder 21 disengages from the limiting long groove 14 formed by the positioning bracket 12, the inner disc 18 will contact the arc groove 13 opened by the positioning bracket 12 and limit the positioning bracket 12. Then, when the four positioning brackets 12 are toggled, they will drive the driven long rod 11 The four limiting ring plates 15 and the four limiting pillars 16 on the driven long rod 11 rotate accordingly. After being transported, the strong steel body 3 will reach the outside of the limiting pillars 16. After being cut by the cutting machine body 1, the limiting pillars 16 will drive the strong steel body 3 to rotate to the bottom. The force generated by the rotation and the factor of gravity will cause the strong steel body 3 to fall off. The four limiting pillars 16 rotate intermittently. After the strong steel body 3 on the limiting pillar 16 at one end of the cutting machine body 1 rotates, the next limiting pillar 16 can immediately reach the designated position, completing the cutting and transportation of the next strong steel body 3, making the structure of the cutting machine body 1 compact. When the limiting assembly is correcting the outside of the strong steel body 3, the limiting pillars 16 on the inner wall of the strong steel body 3 can support and correct it, achieving the purpose of correcting both the inside and outside of the strong steel body 3 at the same time.

[0035] The working principle provided by the present invention is as follows: when the present invention is implemented, through the arrangement of the first bracket 4, the second bracket 5, and the limiting external frame 6, when the cutting blade 2 moves obliquely to cut the strong steel body 3, the connecting brackets 7 on both sides of the cutting blade 2 will move relatively accordingly. When the cutting blade 2 is at the top, the top of the limiting external frame 6 contacts the strong steel body 3, and the bottom sides of the limiting head 8 contact the first bracket 4 and the second bracket 5. When the cutting blade 2 gradually cuts the strong steel body 3 obliquely, the two ends of the cut surface of the strong steel body 3 will be deformed. At this time, the bottom wall of the limiting head 8 gradually fits with the first bracket 4 and the second bracket 5, causing the first bracket 4 and the second bracket 5 to move downward and gradually fit with the two ends of the limiting external frame 6 set in a "V" shape. When the cutting blade 2 reaches the bottom, the first bracket 4 and the second bracket 5 are completely closed with the limiting outer frame 6 and the strong steel body 3 is corrected. The limiting components respectively arranged on both sides of the cutting blade 2 can simultaneously correct one end of the strong steel body 3 being cut and one end of the strong steel body 3 of the next feed, so that the strong steel body 3 can be corrected at both ends after being cut by the cutting machine body 1, thereby achieving the purpose of high precision on both sides of the strong steel body 3 and reducing subsequent processing. By setting the hinged bracket 9, the first bracket 4 and the second bracket 5 can be expanded as the elastic member 22 expands, and the spring can expand according to the rotation of the hinged bracket 9, so that the spring reduces bending, thereby affecting subsequent cutting. For the purpose of normal operation of the machine body 1, the driving member is started at this time, so that the driving member drives the coaxially arranged outer disc 17 and the inner disc 18 through the shaft, so that the two toggle cylinders 21 on the outer disc 17 rotate, thereby driving the four positioning brackets 12 that are in contact with the inner disc 18, and the toggle cylinder 21 gradually contacts the limiting long groove 14 formed by the four positioning brackets 12 after rotation, so that the four positioning brackets 12 are driven by the toggle cylinder 21 to form an intermittent motion of the positioning bracket 12, and at this time the positioning bracket 12 will pass through the crescent groove 19 on the inner disc 18 to prevent the positioning bracket 12 from getting stuck, and when the toggle cylinder 21 disengages from the limiting long groove 14 formed by the positioning bracket 12, the inner disc 18 will contact the arc groove 13 opened by the positioning bracket 12 The four limiting pillars 16 are in contact with each other and limit the positioning bracket 12. Then, when the four limiting brackets 12 are toggled, the driven long rod 11 will be driven to rotate, and the four limiting ring plates 15 and the four limiting pillars 16 on the driven long rod 11 will move accordingly. The strong steel body 3 will reach the outside of the limiting pillars 16 after being transported. After being cut by the cutting machine body 1, the limiting pillars 16 will drive the strong steel body 3 to rotate to the bottom. The force generated by the rotation and the gravity factor will cause the strong steel body 3 to fall off. The four limiting pillars 16 rotate intermittently, and the strong steel body 3 on the limiting pillars 16 at one end of the cutting machine body 1 can be rotated. The next limiting pillar 16 can immediately reach the designated position to complete the cutting and transportation of the next strong steel body 3, making the structure of the cutting machine body 1 compact.And when the limiting assembly is correcting the outside of the strong steel body 3, the limiting pillar 16 on the inner wall of the strong steel body 3 can support and correct the inside, achieving the purpose of correcting both the inside and outside of the strong steel body 3 at the same time.
