Description

Technical Field

[0001] This invention relates to a dual-purpose device for shearing and cutting round steel, and more particularly to a dual-purpose device for preventing round steel from being flattened and its working method. Background Technology

[0002] With the development of the steel manufacturing industry, steel shapes and sizes have become increasingly diverse. In the production of round steel, longer round steel bars need to be cut to meet different size requirements. However, under current production conditions, it is difficult to configure a dedicated cutting line for each type of steel; often, the same equipment is responsible for cutting multiple types of round steel. This leads to a situation where, due to the different properties of round steel—hardness and load-bearing capacity—the cross-section of the steel is often flattened during cutting, resulting in scrapped steel or the need for secondary processing. This significantly increases production costs and falls far short of meeting the production needs of enterprises. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a dual-purpose shearing and cutting device and its working method for preventing round steel from being flattened at the cross-section, which is adapted to the cutting conditions of round steel with different properties.

[0004] The objective of this invention is achieved as follows: A dual-purpose shearing and cutting device for preventing round steel bars from being flattened includes a support mechanism, a primary rotating mechanism, a secondary rotating mechanism, and a cutter assembly. The support mechanism includes a base and a primary power unit, wherein the base is a circular disc structure, and the inner side of the circular disc of the base has a gear structure, and the primary power unit is installed on the circular disc base. The primary rotating mechanism includes a primary turntable, a secondary power unit, and a fixed pressure plate. The primary turntable is also a circular disc structure with gear structures on both its inner and outer circumferences. The primary turntable is located in the hollow part of the base and meshes with the base. The primary power unit contacts the primary turntable and drives it to rotate 360 ​​degrees. The secondary power unit is installed on the primary turntable. The fixed pressure plate is located at the center of the primary turntable and is a circular disc with a central hollow structure. The fixed pressure plate has a sandwich layer in the middle to allow the guillotine cutter in the tool set to retract. The fixed pressure plate is fixedly connected to the turntable. The secondary rotating mechanism includes a secondary turntable, which is also a circular disc structure. The inner and outer circumferential edges of the secondary turntable have gear structures. The secondary turntable is located in the hollow part of the primary disc and meshes with the primary disc. The secondary power device is in contact with the secondary turntable and is used to drive the secondary turntable to rotate. The tool assembly includes multiple guillotine cutters and connecting rods. The guillotine cutters are located in the middle layer of the fixed pressure plate. Each guillotine cutter has two pin holes, which are connected to the fixed pressure plate and the connecting rod, respectively. The guillotine cutters are arranged around the axis of the equipment. After all the guillotine cutters rotate, their arc surfaces can seamlessly mesh and fill the circular hollow area in the center of the fixed pressure plate, or they can be completely retracted into the middle layer of the fixed pressure plate. The other end of the connecting rod is connected to the secondary turntable.

[0005] Each guillotine cutter is shaped like a curved triangle and has two sharp edges.

[0006] The primary rotating mechanism also includes a mass balance block, which is mounted on the primary turntable.

[0007] The fixed pressure plate is fixedly connected to the turntable by pins.

[0008] The primary turntable and the base are engaged by either a tongue-and-groove joint or a large-ring bearing.

[0009] The secondary turntable engages with the primary turntable via a rotating pin or via a large ring bearing.

[0010] The rotating pin slides in the arc-shaped rotating groove.

[0011] The base, primary turntable, and secondary turntable are made of steel, iron, or non-metallic materials.

[0012] The primary and secondary power units are electric motors, hydraulic motors, or cylinders.

[0013] Choose between shearing or machining based on the different physical properties of the target round steel. When shearing, the secondary rotating mechanism works independently. Driven by the secondary power unit, the cutter group is quickly squeezed towards the axis by the connecting rod. The secondary power unit continues to work. Finally, the cutter group works together to form a seamless arrangement in the station, which symmetrically shears the target round steel. Because the round steel is subjected to uniform force, the end face of the round steel will not be flattened. During the cutting process, the primary and secondary rotating mechanisms work together. First, the primary rotating mechanism rotates rapidly under the drive of the primary power unit. Since the secondary rotating mechanism is mounted on the primary rotating disk, it rotates at the same speed and concentrically as the primary rotating mechanism. However, driven by the secondary power unit, the secondary rotating mechanism also rotates slowly relative to the primary rotating mechanism. At this time, the tool assembly begins to move towards the axis. When the tool tip contacts the target round steel, the target round steel begins to be cut because both the primary and secondary mechanisms are rotating synchronously and concentrically at high speed. Next, the secondary power unit continues to work, and the tool assembly continues to move towards the center, completely cutting off the target round steel and completing the work.

[0014] The present invention provides a dual-purpose shearing and cutting device for preventing round steel bars from being flattened, and its working method has the following advantages: This invention enables the shearing or machining of round steel bars with different properties. Due to its unique design, the round steel is subjected to uniform stress during the cutting process, resulting in a circular cross-section without flattening. Furthermore, this invention can address the specific characteristics of round steel bars with varying hardness and dimensions by selecting the shearing or machining method based on the target round steel's different physical properties, significantly improving production efficiency.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific examples described herein are only for explaining the present invention and are not limited to the present invention.

[0025] See Figures 1 to 3 This invention relates to a dual-purpose shearing and cutting device for preventing round steel bars from being flattened. It includes a support mechanism, a primary rotating mechanism, a secondary rotating mechanism, and a cutting tool assembly.

[0026] The support mechanism includes a base 2 and a primary power unit 12. The base 2 is a circular disc-shaped structure with a hollow center. The inner side of the disc has a gear structure. The primary power unit 12 is mounted on the circular disc-shaped base 2 and drives the primary rotating mechanism. As the foundation of the entire device, the support mechanism does not move actively but is connected to the external structure, allowing it to move along with the external structure and thus drive the overall movement of the device. Preferably, the base 2 can be made of steel, iron, non-metallic materials, or any material with sufficient strength. Preferably, the primary power unit 12 can be an electric motor, hydraulic motor, cylinder, or other mechanism capable of driving the primary rotating mechanism to rotate.

[0027] The primary rotating mechanism includes a primary turntable 4, a mass balance block 5, a secondary power unit 8, and a fixed pressure plate 10. The primary turntable 4 is also a circular disc structure, with gear structures on both its inner and outer circumferences. The primary turntable 4 is located at the hollowed-out portion of the base 2 and meshes with it. The primary power unit 12 contacts the primary turntable 4 and drives it to rotate 360 ​​degrees. The secondary power unit 8 and the mass balance block 5 are respectively installed on the left and right sides of the primary turntable 4. The secondary power unit 8 drives the secondary rotating mechanism, and the mass balance block 5 balances the eccentricity that occurs during rotation. The fixed pressure plate 10 is located at the center of the primary turntable 4 and is a centrally hollowed-out disc. The fixed pressure plate 10 has a sandwich structure in the middle to allow the guillotine cutter 9 in the tool assembly to retract. The fixed pressure plate 10 is fixedly connected to the turntable 4 by pins 1, maintaining a stationary position. Preferably, the primary turntable 4 can be made of steel, iron, non-metallic materials, or any material with a certain strength. Preferably, the secondary power unit 8 can be a motor, hydraulic motor, cylinder, or other mechanism capable of driving the secondary rotating mechanism to rotate. Preferably, the engagement method between the primary turntable 4 and the base can be a groove engagement or a large-ring bearing engagement.

[0028] The secondary rotating mechanism includes a secondary turntable 6, which is also a circular disc structure. Both the inner and outer circumferential edges of the secondary turntable 6 have gear structures. The secondary turntable 6 is located at the hollowed-out area of ​​the primary disc 4 and meshes with it. The secondary power device 8 contacts the secondary turntable 6 and drives it to rotate within a certain angle. Preferably, the secondary turntable 6 meshes with the primary turntable 4 via a rotating pin 7 or a large-ring bearing. Preferably, the material of the secondary turntable 6 can be steel, iron, non-metallic materials, or any material with a certain strength. Specifically, the rotating pin 7 slides in an arc-shaped rotating groove, ensuring that the secondary turntable 6 rotates relative to the axis of the device.

[0029] The tool assembly includes five guillotine cutters 9 and a connecting rod 11. The guillotine cutters 9 are housed in the middle layer of the fixed pressure plate 10. Each guillotine cutter 9 is generally triangular with an arcuate shape and double-edged. Each guillotine cutter 9 has two pin holes, which connect to the fixed pressure plate 10 and the connecting rod 11 respectively. The five guillotine cutters 9 are arranged around the axis of the equipment. After rotation, their arcuate surfaces can seamlessly engage and fill the circular hollow area at the center of the fixed pressure plate 10, or they can be completely retracted into the middle layer of the fixed pressure plate 10. The other end of the connecting rod 11 is connected to the secondary turntable 6. Specifically, the guillotine cutters 9 are made of high-strength, high-hardness, and wear-resistant material.

[0030] The working principle of this invention is as follows: Choose between shearing or machining based on the different physical properties of the target round steel: During shearing, the secondary rotating mechanism operates independently. Driven by the secondary power unit, the cutter assembly rapidly compresses towards the axis under the influence of the connecting rod. The secondary power unit continues to operate, ultimately resulting in a seamless arrangement of the cutter assembly within the workstation, symmetrically shearing the target round steel. Due to the uniform force on the round steel, the three end faces of the round steel will not be flattened. The dynamic process is as follows: Figures 4 to 8 As shown.

[0031] During the turning process, the primary and secondary rotating mechanisms work together. First, the primary rotating mechanism rotates rapidly under the drive of the primary power unit. Since the secondary rotating mechanism is mounted on the primary rotating plate, it rotates at the same speed and concentrically as the primary rotating mechanism. However, driven by the secondary power unit, the secondary rotating mechanism also rotates slowly relative to the primary rotating mechanism. At this point, the tool assembly begins to move towards the axis. When the tool tip contacts the target round steel, because both the primary and secondary mechanisms are rotating synchronously and concentrically at high speed, the target round steel begins to be turned. Next, the secondary power unit continues to work, and the tool assembly continues to move towards the center, ultimately achieving the desired result. Figure 8 As shown, the target round steel bar has been completely cut off, and the work is complete.

[0032] The key to this invention lies in: 1. The secondary rotating mechanism can rotate at a certain angle under the drive of the secondary power device, thereby driving the tool set to squeeze towards the center. The ingenious tool shape design allows the tools to "fill" the central circular area, completing the shearing work.

[0033] 2. The primary rotating mechanism can rotate 360 ​​degrees under the drive of the primary power unit, thereby driving the secondary rotating mechanism to rotate as a whole, forming a "turning" state and completing the turning work.

[0034] 3. The primary and secondary rotating mechanisms are responsible for shearing and machining respectively. They work together to select either shearing or machining based on the actual condition of the target round steel, completing the final cutting task. Because the force on the target round steel is directed towards the axis, flattening of the cross-section during the cutting process is avoided.
