[0033] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0034] refer to Figures 1-5 This application provides a notch shearing device, including a mounting bracket 100, a cutter 200 and a drive component 300.

[0035] The mounting frame 100 includes a support base 110 and a material placement seat 120 disposed on the support base 110. The support base 110 of the mounting frame 100 provides a solid foundation for the entire device, capable of withstanding the large reaction force generated when the cutter 200 shears the workpiece 500, ensuring the stability of the device during operation. The material placement seat 120 plays a good positioning role for the workpiece 500, ensuring that the workpiece 500 maintains a fixed position during the shearing process.

[0036] The support base 110 needs to possess sufficient strength and rigidity to ensure the stability and reliability of the device during operation. The support base 110 is typically made of metal, such as steel. The material holder 120 is used to place the workpiece 500 to be processed and to withstand the reaction force generated when the cutter 200 shears the workpiece 500. The material holder 120 is made of wear-resistant and corrosion-resistant materials, such as stainless steel or specially treated metals, to ensure its service life.

[0037] The cutter 200 includes a first end 210, a middle portion 220, and a second end 230. The middle portion 220 is located between the first end 210 and the second end 230 and is rotatably connected to the support base 110. The rotatable connection of the middle portion 220 of the cutter 200 to the support base 110 ensures that the cutter 200 maintains a stable trajectory during rotation, reducing shearing errors caused by wobbling or offset and improving the reliability of the device.

[0038] The drive unit 300 is connected to the first end 210 and drives the cutter 200 to rotate, causing the second end 230 to cut the workpiece 500 on the material holder 120 to form a notch 510 on the workpiece 500. Under the drive of the drive unit 300, the second end 230 of the cutter 200 cuts the workpiece 500 according to a predetermined trajectory, thereby forming a precise notch 510 on the workpiece 500.

[0039] The drive unit 300 can quickly and stably drive the cutter 200 to rotate, enabling the second end 230 of the cutter 200 to rapidly complete the shearing action on the workpiece 500. Compared with manual operation or some inefficient machining methods, this greatly shortens the processing time of a single workpiece 500 and improves production efficiency. At the same time, due to the high degree of automation of the notch shearing device, manual intervention can be reduced, further improving processing efficiency.

[0040] The drive component 300 can take various forms, such as a motor or a cylinder. If a motor is used as the drive component 300, the cutting speed and direction of the cutter 200 can be controlled by adjusting the motor's speed and direction. If a cylinder is used as the drive component 300, it features fast response and high output force, making it suitable for applications requiring high cutting speed or large cutting force.

[0041] In this application, the notch shearing device mainly consists of a mounting frame 100, a cutter 200, and a drive component 300, with a simple overall structure. Compared to complex traditional machining equipment, it has fewer parts and a relatively simple manufacturing process, thereby reducing the manufacturing cost of the equipment.

[0042] In actual use, the operator only needs to place the workpiece 500 to be processed on the material holder 120, start the drive unit 300, and the drive unit 300 will drive the cutter 200 to rotate, so that the second end 230 of the cutter 200 cuts the workpiece 500, forming a notch 510 on the workpiece 500. The whole operation process is simple, reducing the requirements for operators and improving work efficiency. Because the drive unit 300 can quickly drive the cutter 200 to rotate and complete the cutting action, the entire processing process can be completed in a short time, greatly shortening the processing time of a single workpiece 500, which can meet the needs of large-scale production and improve the production capacity of enterprises.

[0043] In one embodiment, the drive component 300 includes a drive cylinder 310 and a piston rod 320. The drive cylinder 310 and the piston rod 320 are telescopically connected, and the other end of the piston rod 320 is connected to the first end 210. The drive cylinder 310 is one of the core components of the drive component 300, providing the power source for the entire shearing action. The drive cylinder 310 can be a hydraulic cylinder or a pneumatic cylinder. Hydraulic cylinders can provide larger output forces and are suitable for applications requiring high shearing force. The piston rod 320 is an extension of the piston inside the drive cylinder 310. It is connected to the piston and performs telescopic movement under the action of hydraulic or pneumatic pressure inside the drive cylinder 310. One end of the piston rod 320 is fixedly connected to the piston inside the drive cylinder 310, and the other end is connected to the first end 210 of the cutter 200.

[0044] The drive cylinder 310 transmits power stably to the cutter 200 via the piston rod 320, enabling the cutter 200 to perform shearing actions at a predetermined speed and force. For the hydraulic cylinder, by adjusting the pressure and flow rate of the hydraulic system, the extension and retraction speed and output force of the piston rod 320 can be precisely controlled, thus achieving flexible adjustment of the shearing speed and shearing force. The drive cylinder 310 and piston rod 320 have relatively simple structures and fewer parts, making the device easier to maintain and service.

[0045] The first end 210 is a hinge seat, and the end of the piston rod 320 away from the drive cylinder 310 is connected to a first hinge shaft 330, which is hinged to the first end 210. Specifically, the piston rod 320 extends and retracts under the action of the drive cylinder 310, transmitting power to the cutter 200 through the first hinge shaft 330. The first end 210 of the cutter 200 is hinged to the piston rod 320, allowing for flexible relative rotation between the piston rod 320 and the cutter 200. During the extension and retraction of the piston rod 320, the linear motion of the piston rod 320 is converted into the rotational shearing motion of the cutter 200, making the transmission smoother.

[0046] The middle part 220 of the cutter 200 is a hinge hole, and the support base 110 is provided with a second hinge shaft 111, which passes through the hinge hole. The middle part 220 of the cutter 200 is set as a hinge hole, which is a hole that passes through the cutter 200 and is used to cooperate with the second hinge shaft 111 on the support base 110 to realize the rotational connection of the cutter 200.

[0047] The cutter 200 is connected to the second hinge shaft 111 on the support base 110 via a hinge hole, allowing the cutter 200 to rotate stably around the second hinge shaft 111. This rotation method ensures the accurate movement trajectory of the cutter 200 during the shearing process, reduces shearing errors caused by the wobble or deviation of the cutter 200, and improves the quality and precision of the shearing.

[0048] The second end 230 of the cutter 200 is a cutting edge, and the material holder 120 is provided with a material discharge groove 130. The second end 230 can pass through the workpiece 500 and enter the material discharge groove 130. The second end 230 of the cutter 200 is set as a cutting edge, which is the part that actually performs the shearing work. The cutting edge is usually made of high-hardness, high-wear-resistant materials, such as high-speed steel and cemented carbide.

[0049] The blade design allows the cutter 200 to quickly and effectively cut into the workpiece 500, achieving efficient shearing. The material discharge groove 130 ensures that the sheared waste material can be discharged in a timely manner, preventing waste material from accumulating on the workpiece 500 and affecting subsequent processing, further improving processing efficiency. Furthermore, the presence of the material discharge groove 130 allows the cutter 200 to smoothly pass through the workpiece 500 during the shearing process, reducing problems such as incomplete shearing or surface damage to the workpiece 500 caused by waste material jamming, thus ensuring the processing quality of the workpiece 500.

[0050] In one embodiment, the distance between the first hinge shaft 330 and the second hinge shaft 111 is greater than the distance between the second hinge shaft 111 and the second end 230. Specifically, according to the lever principle, when the distance between the first hinge shaft 330 and the second hinge shaft 111 is greater than the distance between the second hinge shaft 111 and the second end 230, the force applied by the piston rod 320 to the first hinge shaft 330 can generate a larger shearing force acting on the blade. This design allows the device to achieve a large shearing force with a smaller driving force, reducing the requirements on the drive component 300 and saving energy and cost.

[0051] refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The material holder 120 includes a first end face 121 and a second end face 122 disposed opposite to each other. A material discharge groove 130 passes through the first end face 121 and the second end face 122. The first end face 121 is used to place the workpiece 500. The distance between the first end face 121 and the second end face 122 gradually decreases from the area near the material discharge groove 130 to the surrounding area. Specifically, the workpiece 500 is placed on the first end face 121, and the distance between the first end face 121 and the second end face 122 gradually decreases from the area near the material discharge groove 130 to the surrounding area, so that the material holder 120 forms a raised area near the material discharge groove 130. When the cutter 200 cuts the workpiece 500, the force on the workpiece 500 is concentrated near the position of the material discharge groove 130, which facilitates the cutting and shaping of the notch 510.

[0052] In the axial direction of the second hinge shaft 111, the size of the material discharge groove 130 near the first end face 121 is smaller than the size of the material discharge groove 130 near the second end face 122.

[0053] The smaller size of the discharge chute 130 near the first end face 121 increases the support area of ​​the material holder 120 for the workpiece 500. The larger size of the discharge chute 130 near the second end face 122 facilitates the smooth discharge of waste material, avoids waste material getting stuck in the discharge chute 130, and improves the efficiency of waste material discharge.

[0054] The second end 230 of the cutter 200 has an arc-shaped cutting edge. The arc-shaped working part of the cutter 200 can make the contact between the cutting edge and the workpiece 500 more uniform during the cutting process, reduce local stress concentration, thereby reducing the wear rate of the cutting edge and extending the service life of the cutting edge.

[0055] In one embodiment, the notch shearing device further includes a cover plate 400. A receiving groove 112 is provided on the support base 110, and the cutter 200 is disposed in the receiving groove 112. The cover plate 400 covers the opening of the receiving groove 112. Specifically, the receiving groove 112 provides space for the installation and movement of the cutter 200. The cover plate 400 covers the opening of the receiving groove 112 on the support base 110, preventing external dust, debris, etc., from entering the receiving groove 112, thus avoiding contamination and damage to the cutter 200 and extending its service life. Simultaneously, the presence of the cover plate 400 prevents operators from accidentally contacting the cutter 200 during device operation, reducing the occurrence of safety accidents and improving operational safety.

[0056] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
