Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment and relates to a flying shear disc device. Background Art

[0002] In the production line of metallurgical steel rolling, the shearing of rolled pieces is a key link, which is directly related to the efficiency and quality of the production line. However, there are many problems in the current steel rolling production line, which restrict the rapid development of metallurgical steel rolling production. For example, the current steel rolling production efficiency is low and the failure rate is high. The shearing speed of rolled pieces is slow. During the high-speed shearing process, the rolled pieces often cannot enter the subsequent channel smoothly, causing steel pile accidents. During the rolling process, the steel will undergo certain plastic deformation after cooling, causing changes in its internal structure. However, the current flying shear disc device has a slow shearing speed and cannot cut the steel into a specified length before cooling, causing excessive deformation of the steel and degradation of its performance.

[0003] Therefore, it is urgent to propose a flying shear disc device to reduce the failure rate, improve the efficiency of the production line, and ensure the quality of the rolled piece after shearing. Utility Model Content

[0007] The guide block is set close to the blade, and the guide block cooperates with the blade. After the blade cuts off the workpiece, the side of the workpiece behind the blade's rotation path contacts the guide block. The guide block applies a lateral force away from the cutter disc seat to the workpiece.

[0029] See also Figure 1-2 , is a flying shear disc device, installed on a flying shear machine, including a cutter disc seat 1, the cutter disc seat 1 is a cylindrical structure, made of steel, and the cutter disc seat 1 rotates around its axis; a plurality of blades 2 are symmetrically arranged on the side of the cutter disc seat 1, and the blades 2 are fixed to the side of the cutter disc seat 1 by bolts, and the number of blades 2 is determined according to the length of the rolled piece to be broken. When the length of the rolled piece to be broken is longer, the number of blades 2 can be reduced, and conversely, when the length of the rolled piece to be broken is shorter, the number of blades 2 can be increased; in some embodiments of the utility model, four blades 2 are symmetrically arranged on each cutter disc seat 1.

[0030] The cutter head seat 1 is fixedly connected to the output shaft of the flying shear by bolts to realize the rotation of the cutter head seat 1 around the axis. The cutter head seat 1 can be set as one, or as two cutter heads arranged tangentially up and down; when the cutter head seat 1 is set as one, the cutter head seat 1 is tangentially arranged just above or just below the workpiece; when the cutter head seat 1 is set as two, the workpiece is located at the middle tangential position between the upper and lower cutter heads to realize the shearing function of the workpiece.

[0031] The side of the cutter head 1 is tangent to the workpiece. When the cutter head 1 rotates, the linear speed of the tangent point is equal to the speed of the workpiece movement and has the same direction, so the head and tail of the workpiece can be cut, broken, and even broken in case of accidents (when an accident occurs during the rolling process, the flying shear breaking function is automatically started to perform continuous shearing, shearing and breaking the workpiece to prevent the accident from further expanding, thereby ensuring production safety).

[0032] A slot is provided on the side of the cutter disc seat 1, and the blade 2 is fixed in the slot of the cutter disc by bolts. The slot is in the form of a long hole, and a gasket 5 is also provided in the slot to facilitate adjustment of the position of the blade 2 in the slot. When an upper and lower cutter disc seat 1 is provided, the distance between the blades 2 on the upper and lower cutter disc seats 1 can be adjusted by adjusting the gasket 15.

[0033] A guide block 4 is also provided on the side of the cutter disc seat 1. The guide block 4 is closely arranged behind the rotation path of the blade 2. The guide block 4 is rectangular, its width is less than the side width of the cutter disc seat 1, and its height is less than or equal to the height of the blade 2. The guide block 4 is fixedly connected to the cutter disc seat 1 by bolts. The sheared workpiece contacts the guide block 4, and the sheared workpiece is raised or lowered to a suitable height by the guide block 4, so as to guide the sheared workpiece to enter the downstream channel smoothly. The guide block 4 contacts the side of the workpiece and applies a lateral force to it, thereby achieving the purpose of lowering or raising the workpiece. Specifically, when the guide block 4 applies a lateral force to the workpiece, it pushes the workpiece to one side, causing the workpiece to deviate from the original linear motion trajectory, thereby achieving the effect of adjusting the height of the workpiece. The guide block 4 installed on the upper cutter disc seat 1 presses down the rear workpiece, and the guide block 4 installed on the lower cutter disc seat 1 raises the rear workpiece.

[0034] The guide block 4 is prone to wear during long-term use and can be replaced with a new guide block 4, which is convenient for later maintenance.

[0035] An adjustment block 3 is provided on the bottom surface of the cylinder of the cutter head seat 1. The adjustment block 3 is fixedly connected to the cutter head seat 1 by bolts, and the center of gravity of the cutter head device can be adjusted according to the unbalanced state of the cutter head device to control the vibration amplitude of the cutter head device under high speed conditions. In some embodiments of the utility model, the adjustment block is a fan-shaped strip.

[0036] When the cutter disc device is unbalanced, it may cause problems such as machine vibration, excessive wear, and may even damage other parts of the machine. The function of the adjustment block 3 is to make the mass distribution of the cutter disc more even by fine-tuning the height and front and rear position of the cutter. If the front of the cutter disc is heavier, a counterweight can be added to the rear, and vice versa. Through such adjustments, the imbalance problem is solved, the cutter disc is balanced, vibration and wear are reduced, the service life and stability of the machine are improved, and the accuracy and effect of processing are ensured.

[0037] A weight block matched with the adjustment block 3 can also be set. The number and position of the weight blocks are adjusted according to the unbalanced state of the flying shear disc device, so that the cutter disc device is in a state of uniform mass distribution and rotational balance, further ensuring the accuracy and consistency of the size of the rolled piece after shearing. Specific embodiment one:

[0039] There are two cutter disc seats 1, namely, an upper cutter disc seat 1 and a lower cutter disc seat 1 arranged up and down and tangent to each other. The upper and lower cutter disc seats 1 have the same structure. The blade 2 of the upper cutter disc seat 1 is opposite to the blade 2 of the lower cutter disc seat 1. During the shearing and breaking process, the upper and lower cutter disc seats 1 rotate along their respective axis lines at the same speed and in opposite directions. The workpiece is located at the tangent point of the upper and lower cutter disc seats 1. At the tangent point, the speed of the tangent point of the upper and lower cutter disc seats 1 is the same as the speed of the moving workpiece, and the direction is also the same. The number and spacing of the blades 2 set on the upper and lower cutter disc seats 1 are the same. During the rotation of the upper and lower cutter disc seats 1, the blade 2 of the upper cutter disc seat 1 contacts the blade 2 of the lower cutter disc seat 1 to achieve the effect of shearing and breaking the workpiece.

[0040] The upper and lower cutter disc seats 1 are respectively provided with guide blocks 4. The guide blocks 4 arranged on the upper cutter disc seat 1 can lift the rolled piece after shearing to a suitable height, and the guide blocks 4 arranged on the lower cutter disc seat 1 can press the rolled piece after shearing to a suitable height to guide the rolled piece to smoothly enter the downstream channel.

[0041] The utility model is suitable for high-speed flying shears on high-speed wire and bar production lines. The flying shear disc device of the utility model is installed on the high-speed flying shear. Through a plurality of blades arranged on the flying shear disc device, the size of the rolled piece can be accurately controlled, and the rolled piece can be sheared into a required length and width, thereby ensuring the accuracy and consistency of the product size; and due to the multiple blades arranged, the steel is cut into a specified length before cooling, thereby eliminating the quality defects of the rolled piece and avoiding the degradation of steel performance due to excessive deformation; combined with the guide block arranged behind the rotating path of the blade, the sheared rolled piece is quickly guided into the downstream channel to prevent the rolled piece from colliding with subsequent equipment such as the guide groove to cause steel piling accidents, thereby ensuring the smoothness of the shearing process, further improving the production efficiency, reducing the failure rate, and reducing manual intervention and downtime; the product specifications can also be quickly adjusted to adapt to changes in market demand to meet the different needs of the market.
