Description

[0001] This application claims priority to the earlier application filed on May 30, 2025, application number 2025210993974. Technical Field

[0002] This utility model relates to the field of shearing machine technology, and in particular to a shearing machine based on hot-rolled composite coil. Background Technology

[0003] During the winding process of composite coils, after the required length is reached, the coil needs to be cut by a shearing machine. Existing shearing machines generate a large amount of metal shavings, oxide scale, and other impurities during the cutting process. These impurities easily adhere to the blade surface. The accumulation of impurities not only affects the cutting accuracy of the blade, causing problems such as burrs and unevenness at the cut of the coil, but may also accelerate blade wear and shorten the blade's service life. Therefore, a shearing machine based on hot-rolled composite coils is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] Shearing machine based on hot-rolled composite coil includes:

[0006] Organism;

[0007] The shearing assembly includes a blade slidably disposed within the machine body, two sets of movable rods disposed on the top of the blade, and a spring sleeved on the movable rods. The top of the movable rods passes through the top of the machine body and is provided with a limiting block.

[0008] The cleaning assembly includes two sets of cylinders symmetrically fixed to the top of the machine body, piston rods slidably disposed in the cylinders, connecting plates connecting the bottom of the two piston rods, and fixed tubes disposed on both sides of the blade. The fixed tubes have air outlet holes evenly distributed along their length on their inner side. The bottom of the air outlet of the cylinders is connected to the fixed tubes through a unidirectional air outlet pipe.

[0009] The driving component includes a cam disposed between the connecting plate and the blade;

[0010] The cam is driven to rotate. When the protruding part of the cam pushes the connecting plate to move upward, the connecting plate compression cylinder generates compressed airflow, which is delivered to the fixed pipe through the air outlet and sprayed onto the blade surface through the air outlet. When the protruding part of the cam pushes the blade to move downward, the roll material is cut.

[0011] As an improvement to the above technical solution, a piston is provided inside the cylinder, which divides the cylinder cavity into chamber one and chamber two from top to bottom. The bottom of the piston is fixedly connected to the piston rod. Chamber one is connected to the air outlet pipe. A one-way flow air inlet pipe is provided on the side wall of the cylinder at the position of chamber one. A spring two is wound around the surface of the piston rod inside the cylinder. When the blade cuts downward, the piston moves downward under the thrust of spring two, and a negative pressure is formed in chamber one, which draws in air through the air inlet pipe. When the blade moves upward, the piston moves upward and compresses the air in chamber one. The gas flows through the air outlet pipe into the fixed pipe to blow away debris on the blade surface.

[0012] As an improvement to the above technical solution, the driving component includes a rotating shaft rotatably inserted into the cam and a motor. One end of the rotating shaft passes through the machine body and extends to the outside of the machine body. The end of the rotating shaft extending to the outside of the machine body is fixedly connected to the output end of the motor.

[0013] As an improvement to the above technical solution, an avoidance groove is provided at the bottom of the inner wall of the machine body and below the blade.

[0014] The beneficial effects of this utility model are:

[0015] By using a cam, the single rotational motion is synchronously converted into the reciprocating motion of blade cutting and gas cleaning, achieving precise timing coordination of "cleaning first, then cutting" and avoiding debris residue affecting cutting accuracy.

[0016] When the cam drives the cylinder to generate compressed airflow, it blows the blade surface in a directional manner through the fixed tube, removing impurities such as metal chips and oxide scale in real time. At the same time, it carries away the heat generated during cutting, thereby reducing the working temperature of the blade and extending its service life. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Shearing machine based on hot-rolled composite coil includes:

[0023] Body 10;

[0024] The shearing assembly includes a blade 20 slidably disposed within the body 10, two sets of movable rods 22 disposed on the top of the blade 20, and a spring 21 sleeved on the movable rods 22. The top end of the movable rod 22 passes through the top of the body 10 and is provided with a limiting block.

[0025] The cleaning assembly includes two sets of cylinders 50 symmetrically fixed to the top of the body 10, piston rods 53 slidably disposed in the cylinders 50, connecting plates 54 connecting the bottoms of the two piston rods 53, and fixed tubes 30 disposed on both sides of the blade 20. The fixed tubes 30 have air outlets evenly distributed along their length direction on their inner side. The bottom of the air outlet of the cylinders 50 is connected to the fixed tubes 30 through a unidirectional air outlet pipe 52.

[0026] The driving component includes a cam disposed between the connecting plate and the blade;

[0027] The cam 40 is driven to rotate. When the protruding part of the cam 40 pushes the connecting plate 54 to move upward, the connecting plate 54 controls the compression cylinder 50 to generate compressed airflow, which is delivered to the fixed pipe 30 through the air outlet pipe 52 and sprayed onto the surface of the blade 20 through the air outlet. When the protruding part of the cam 40 pushes the blade 20 to move downward, the roll material is cut.

[0028] Specifically, when the protruding part of the cam 40 pushes the blade 20 downward, the blade 20 slides downward along the inside of the machine body 10 to cut the hot-rolled composite coil. After cutting, the cam 40 rotates to the non-protruding part, the spring 21 resets, and pushes the blade 20 upward to return to the initial position. The spring 21 provides the reset force, and the limit block restricts the stroke of the movable rod 22 to ensure that the blade 20 rises and falls smoothly and is positioned accurately. When the protruding part of the cam 40 pushes the connecting plate 54 upward, the connecting plate 54 drives the piston rods 53 on both sides to slide upward in the cylinder 50, compressing the air in the cylinder 50 and generating compressed airflow. The compressed airflow passes through a one-way... The air outlet pipe 52 delivers air to the fixed pipes 30 on both sides of the blade 20. The air is sprayed onto the surface of the blade 20 through the evenly distributed air outlet holes inside the fixed pipe 30, blowing off metal scraps, oxide scale and other impurities remaining during the cutting process. At the same time, it reduces the heat on the surface of the blade 20. When the cam 40 rotates to the non-protruding part, the piston rod 53 resets under the action of the spring force. Through the geometric shape of the cam 40 profile, the rotational motion is converted into the up-and-down reciprocating motion of the blade 20 and the up-and-down reciprocating motion of the connecting plate 54, realizing the coordinated action of the two. When the protruding part of the cam 40 pushes the connecting plate 54 upward first, generating compressed gas, and then pushes the blade 20 downward, the cutting is performed.

[0029] In one embodiment, a piston 51 is provided inside the cylinder 50. The piston 51 divides the cavity of the cylinder 50 into a first chamber and a second chamber from top to bottom. The bottom of the piston 51 is fixedly connected to the piston rod 53. The first chamber is connected to the air outlet pipe 52. A one-way flow air inlet pipe 56 is provided on the side wall of the cylinder 50 at the location of the first chamber. A second spring 55 is wound on the surface of the piston rod 53 inside the cylinder 50. When the blade 20 cuts downward, the piston 51 moves downward under the push of the second spring 55, and the first chamber forms a negative pressure to draw in air through the air inlet pipe 56. When the blade 20 moves upward, the piston 51 moves upward to compress the air in the first chamber. The gas flows through the air outlet pipe 52 into the fixed pipe 30 to blow away debris on the surface of the blade 20.

[0030] Stage 1: Blade 20 cuts (cutting process)

[0031] Cam 40 pushes blade 20 downward, at which time connecting plate 54 moves downward as well. At the same time, piston rod 53 drives piston 51 to move downward under the elastic force of spring 2 55, which increases the space of chamber one and forms negative pressure. At this time, external air is drawn into chamber one, and the air outlet pipe 52 is closed due to the one-way valve.

[0032] Phase 2: Blade 20 moves upward (reset after cutting).

[0033] When the cam 40 rotates to the non-protruding part, the blade 20 moves upward and resets under the action of the spring 21. The protruding part of the cam pushes the connecting plate 54 to move upward, which in turn pulls the piston 51 upward through the piston rod 53, compressing the air in the first chamber. The pressure in the first chamber increases, the one-way air inlet pipe 56 closes, and the one-way air outlet pipe 52 opens. The compressed air is delivered to the fixed pipe 30 through the air outlet pipe 52 and sprayed onto the surface of the blade 20 through the air outlet to remove debris.

[0034] During the downward cutting process of blade 20, air is drawn into the chamber to prepare for cleaning. Blade 20 moves upward to reset, triggering air blowing for cleaning, so that debris is removed from blade 20.

[0035] In one embodiment, the driving component includes a rotating shaft 41 rotatably inserted into the cam 40 and a motor. One end of the rotating shaft 41 passes through the body 10 and extends to the outside of the body 10. The end of the rotating shaft 41 extending to the outside of the body 10 is fixedly connected to the output end of the motor. When the motor is powered on, the output shaft drives the rotating shaft 41 to rotate, thereby driving the cam 40 to perform circular motion around the axis of the rotating shaft 41.

[0036] In one embodiment, a clearance groove is provided at the bottom of the inner wall of the machine body 10 and below the blade 20. When the blade 20 cuts to the lowest point, the blade can be embedded in the clearance groove to prevent direct impact on the bottom of the machine body 10 and extend the life of the blade 20. At the same time, the scraps or debris generated during cutting can fall into the clearance groove to avoid accumulation and affect the cutting accuracy. For thicker composite rolls, the clearance groove provides sufficient cutting space to prevent the material from deforming due to compression and causing uneven cuts.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
