Description

Technical Field

[0001] The utility model relates to the technical field of metal pressure processing, and particularly relates to a novel high-speed bar multiple-length flying shear commutation device. Background Art

[0002] In the production line of high-speed bars in steel rolling, the function of the high-speed multiple-length flying shear is to segment the finished products so that the finished products of a certain length can be sent to the cooling bed. The specific working principle is as follows: The flying shear is a disk shear and is in a rotating state during the production process. Shearing is achieved during the process when the diverter rotates from the left line to the right line or from the right line to the left line. However, during the rotation of the diverter, there is a certain angle between the diverter and the double-sided guide groove after the shear, and there is a distance without the support of the guide groove between the end of the diverter and the guide groove after the shear. Therefore, during the production of small-sized steel bars, problems such as steel blocking or scratching of the tail of the multiple-length often occur at this position.

[0003] Refer to Figures 5 - 6 As shown, by analyzing from the working principle of this mechanism, it is found that during the production process, shearing is achieved during the process when the diverter rotates from the left line to the right line or from the right line to the left line. During the rotation of the diverter, there is a certain angle between the diverter and the double-sided guide groove after the shear, resulting in scratching between the tail of the hot steel finished product and the material distribution box after the shear; after the hot steel finished product is sheared by the multiple-length shear, there is a certain angle between the head of the hot steel finished product and the material distribution box, and problems such as resistance and steel piling caused by the head hitting the material distribution box are likely to occur. Therefore, a novel high-speed bar multiple-length flying shear commutation device is designed to cancel the material distribution box after the shear, synchronize the diverter of the multiple-length shear with the guide groove after the shear, and solve the problems of resistance caused by the head impact of the hot steel finished product and scratching of the tail of the finished product. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel high-speed bar multiple-length flying shear commutation device for the deficiencies and defects in the prior art. By canceling the original material distribution box of the multiple-length shear and adopting a circular hollow conduit, the inlet end of the conduit is a conical horn structure, and then its frame guide rail is added. The frame guide rail is used to rigidly connect the diverter with the conduit after the shear. During the rotation of the diverter, the guide grooves before and after the shear are synchronously operated. After the hot steel multiple-length is sheared, there is no angle when entering the conduit after the shear, reducing the resistance of the hot steel at this position, thereby effectively solving the problem of steel blocking during multiple-length shearing.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: A novel high-speed bar multiple-length flying shear commutation device, which includes a conduit 1 after the shear, a multiple-length flying shear 2, left and right guard plates 3, a frame guide rail 4, and a diverter 5. The left and right guard plates 3 are arranged below the multiple-length flying shear 2, and a conduit 1 after the shear is installed on one side of the multiple-length flying shear 2, and a diverter 5 is installed on the other side of the multiple-length flying shear 2. The conduit 1 after the shear and the diverter 5 are rigidly connected through the frame guide rail 4.

[0006] Further, the frame guide rail 4 includes a frame body 42. A conduit connection end 41 is installed at one end of the frame body 42 close to the post-shearing conduit 1, a diverter connection end 44 is installed at one end of the frame body 42 close to the diverter 5, and a fixed bracket 43 is installed inside the top of the frame body 42.

[0007] Further, the inner cavities of both the post-shearing conduit 1 and the diverter 5 are provided with red steel products 6 to be processed.

[0008] Further, the opening of the post-shearing conduit 1 on the side close to the flying shear 2 is in a conical horn structure.

[0009] Further, guide wheels are installed inside the post-shearing conduit 1.

[0010] Further, the post-shearing conduit 1 is a circular hollow conduit.

[0011] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By canceling the original multiple-length shear dividing box, adopting a circular hollow conduit with a conical horn structure at the inlet end of the conduit, and adding its frame guide rail, using this frame guide rail to rigidly connect the diverter and the post-shearing conduit, the front and post-shearing guide grooves can run synchronously during the rotation of the diverter, and the red steel after multiple-length shearing does not enter the post-shearing conduit at an angle, reducing the resistance of the red steel at this position, thereby effectively solving the problem of steel blocking during multiple-length shearing.

[0020] Refer to Figures 1 - 4 As shown, the technical solution adopted in this specific implementation mode is: It includes a post-cut duct 1, a multiple-length flying shear 2, left and right guard plates 3, a frame guide rail 4, and a deflector 5. Left and right guard plates 3 are provided below the multiple-length flying shear 2, and a post-cut duct 1 is installed on one side of the multiple-length flying shear 2, and a deflector 5 is installed on the other side of the multiple-length flying shear 2. The post-cut duct 1 and the deflector 5 are rigidly connected through the frame guide rail 4.

[0021] More specifically, the frame guide rail 4 includes a frame main body 42. A duct connection end 41 is installed at one end of the frame main body 42 close to the post-cut duct 1, a deflector connection end 44 is installed at one end of the frame main body 42 close to the deflector 5, and a fixed bracket 43 is installed inside the top of the frame main body 42. The post-cut duct 1 and the deflector 5 are respectively connected through the duct connection end 41 and the deflector connection end 44, and are rigidly connected through the fixed bracket 43, so that the deflector 5 realizes synchronous operation of the pre-cut and post-cut guide grooves during rotation, and there is no angle when entering the post-cut duct 1 after the multiple-length flying shear 2, thereby reducing the resistance of the finished red steel 6 at this position.

[0022] More specifically, the inner cavities of the post-cut duct 1 and the deflector 5 are both provided with finished red steel 6 to be processed.

[0023] More specifically, the opening at the side of the post-cut duct 1 close to the multiple-length flying shear 2 is in a conical horn structure. The conical horn structure facilitates the more smooth entry of the finished red steel 6 into the post-cut duct 1 after shearing.

[0024] More specifically, guide wheels are installed on the post-cut duct 1. The guide wheels can ensure that the post-cut guide groove rotates at the rolling line level.

[0025] More specifically, the post-cut duct 1 is a circular hollow duct.

[0026] Working principle of the present utility model: By canceling the original multiple-length shear splitter box, adopting a circular hollow duct, and the inlet end of the post-cut duct 1 is in a conical horn structure, and making the post-cut duct 1 and the deflector 5 rigidly connected through the frame guide rail 4. When the multiple-length flying shear 2 processes the finished red steel 6, there is no angle when entering the post-cut duct 1 after the multiple-length flying shear 2 shears, thereby effectively reducing the resistance of the finished red steel 6 at this position, and effectively solving the problem of steel blocking during the multiple-length flying shear 2.

[0027] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
