Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip cutting technology, specifically a stainless steel strip cutting structure. Background Technology

[0002] Stainless steel strip is a type of steel characterized by its rust resistance and corrosion resistance, with a chromium content of at least 10.5% and a carbon content of no more than 1.2%. It is a metastable austenitic stainless steel with a fully austenitic structure. Its strength and hardness can be significantly improved through cold deformation processing, while retaining sufficient plasticity and toughness.

[0003] In the traditional cutting process of stainless steel strip, the unidirectional rotation of the cutting wheel creates uneven stress distribution. When the cutting blade cuts into the material in a single direction, the steel strip cross-section is subjected to asymmetrical shearing forces. This stress state easily leads to microcracks or burrs at the cut.

[0004] Because stainless steel has high toughness and work hardening properties, the heat generated by unidirectional cutting will concentrate in a localized area, potentially causing changes in the material's metallographic structure. This cutting method can also cause wavy deformation at the edges of the steel strip, affecting the accuracy of subsequent bending, welding, and other processing steps. During operation, the vibration generated at the moment of contact between the cutting wheel and the steel strip is transmitted through the equipment to the entire roll of material, exacerbating the lateral sway of the strip. For thinner precision stainless steel strips, this process defect is particularly noticeable, often requiring additional shaping steps to correct the deformation.

[0005] Chinese patent discloses a steel strip cutting device (authorization announcement number CN201455414U). The patented technology mainly includes a frame, on which a conveying component and a cutting component are provided. The cutting component includes a cutter head and a cylinder connected to the cutter head, and it also includes a control component. The conveying component includes a fixed clamp, a moving clamp, and a moving clamp cylinder. The moving clamp and the moving clamp cylinder are connected by a transmission, and the moving clamp cylinder has a stroke control structure. The control component is electrically connected to the cylinder connected to the cutter head and the moving clamp cylinder, respectively.

[0006] However, this patent still has shortcomings. When cutting stainless steel strips, a cutting device is typically used. However, the cutting wheel on this device performs a unidirectional cut, resulting in low cutting efficiency and a tendency to cause unbalanced cutting forces, leading to deformation of the stainless steel strip. Therefore, those skilled in the art have provided a stainless steel strip cutting structure to solve the problems mentioned in the background. Utility Model Content

[0007] The purpose of this utility model is to provide a stainless steel strip cutting structure that can simultaneously cut both the upper and lower sides of the stainless steel strip, improving cutting efficiency. It also has the advantages of balanced cutting force and reduced deformation of the stainless steel strip. This solves the problem that when stainless steel strip is cut, a cutting device is usually used, but the cutting wheel on the cutting device cuts in one direction, resulting in low cutting efficiency and easy to cause unbalanced cutting force and deformation of the stainless steel strip.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel strip cutting structure, including a workbench and a rotating rod II. A steel strip body is placed on the upper surface of the workbench, a fixing plate is fixed on the lower surface of the workbench, a connecting frame is fixed on the lower surface of the fixing plate, a bracket II is fixed on one side of the connecting frame, and a bracket I is fixed on the upper and lower sides of one side of the bracket II. A cutting wheel is rotatably connected inside the bracket I.

[0009] Preferably, four pillars arranged in a rectangular array are fixed to the lower surface of the worktable. The four pillars support the worktable, making the entire device stable.

[0010] Preferably, the second bracket has a groove at its front end and a circular hole on one side. A motor is fixed to one side of the second bracket, and a drive shaft of the motor extends into the circular hole. A rotating rod is fixed to one side of the drive shaft, and a gear is fixed to one side of the rotating rod. The drive shaft of the motor fixes the rotating rod, providing power for the rotation of the rotating rod and the gear, and simultaneously driving the gear and the cutting wheel to rotate, facilitating the cutting of the steel strip body by the upper and lower cutting wheels.

[0011] Preferably, the front end of the bracket has a groove, and two rotating shafts are rotatably connected to the inner walls of the groove. A circular hole is formed on one side of the bracket, and one side of the rotating rod extends into the circular hole and is rotatably connected. One side of the rotating rod is fixed to the rotating shaft, and a gear is fixed to the other side of the rotating rod. By extending the rotating rod into the circular hole and rotatably connecting it, and by fixing the gear to the other side of the rotating rod, the rotation of the gear drives the rotation of the cutting wheel, facilitating the cutting wheel's cutting of the steel strip body.

[0012] Preferably, gear one and gear two are meshed together, and their vertical centers are aligned. This alignment facilitates their meshing, allowing the cutting wheel to rotate and thus enabling the cutting of the steel strip.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a fixed plate on the lower surface of a workbench, a connecting frame on the lower surface of the fixed plate, a second bracket on one side of the connecting frame, and a first bracket on the upper and lower sides of the second bracket. A cutting wheel is rotatably connected within the first bracket. When stainless steel strip needs to be cut, the strip is placed on the workbench, the motor is started, causing gears one and two to rotate, and the upper and lower cutting wheels to rotate, pushing the strip between the two cutting wheels for cutting. This allows for simultaneous cutting of both the upper and lower surfaces of the stainless steel strip, improving cutting efficiency and balancing the cutting force, thus reducing deformation of the stainless steel strip.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 The present invention provides two embodiments:

[0024] Example 1: A stainless steel strip cutting structure includes a workbench 2 and a rotating rod 17. A steel strip body 3 is placed on the upper surface of the workbench 2. A fixing plate 11 is fixed on the lower surface of the workbench 2. A connecting frame 10 is fixed on the lower surface of the fixing plate 11. A bracket 5 is fixed on one side of the connecting frame 10. A bracket 4 is fixed on the upper and lower sides of one side of the bracket 5. A cutting wheel 9 is rotatably connected inside the bracket 4.

[0025] Four pillars 1 arranged in a rectangular array are fixed on the lower surface of the workbench 2;

[0026] The second bracket 5 has a groove 14 at the front end, a round hole 13 on one side of the second bracket 5, a motor 8 fixed on one side of the second bracket 5, a drive shaft of the motor 8 extending into the round hole 13 on one side, a rotating rod 12 fixed on one side of the drive shaft of the motor 8, and a gear 7 fixed on one side of the rotating rod 12.

[0027] The motor 8 is equipped with a drive shaft that fixes the rotating rod 12, which provides power for the rotation of the rotating rod 12 and the gear 7. At the same time, it can drive the gear 6 and the cutting wheel 9 to rotate, so that the cutting wheel 9 can cut the steel strip body 3. The motor 8 is electrically connected to an external power source.

[0028] Motor 8 is a servo motor, a precision control motor whose structure and working principle embody a high degree of mechatronics integration. Structurally, a servo motor mainly consists of core components such as a stator, rotor, encoder, and drive controller. The stator is typically made of laminated silicon steel sheets with three-phase windings, similar to the structure of a regular AC motor, but with higher manufacturing precision. The rotor can be divided into permanent magnet rotors and wound rotors, with permanent magnet rotors using high-performance rare-earth magnets, resulting in a stronger magnetic field and smaller size. The encoder, serving as a position feedback device, is tightly mounted at the rear end of the motor shaft; common types include photoelectric encoders and magnetic encoders, capable of real-time rotor position detection. The drive controller contains power electronic circuitry and a microprocessor, responsible for receiving control signals and driving the motor.

[0029] The working principle of a servo motor is essentially a closed-loop control system. When the controller receives a position, speed, or torque command, it first obtains the actual position information of the motor through an encoder. Then, it compares the command value with the actual value and calculates the error signal. This error signal is processed by the control algorithm to generate a corresponding three-phase PWM drive signal, which is applied to the stator windings through a power inverter to generate a rotating magnetic field. The permanent magnet rotor begins to rotate under the action of the rotating magnetic field, while the encoder continuously monitors the rotor position, forming a closed-loop feedback.

[0030] In this embodiment, when it is necessary to cut the stainless steel strip, the strip body 3 is placed on the workbench 2, the motor 8 is started, so that gear 6 and gear 7 rotate, and the cutting wheel 9 rotates at the same time, and the cutting wheel 9 can cut the stainless steel strip.

[0031] Example 2:

[0032] The front end of the bracket 14 has a groove 16, and the inner walls of the groove 16 are rotatably connected to the rotating shafts 15. The bracket 14 has a round hole 2 18 on one side, and one side of the rotating rod 2 17 extends into the round hole 2 18 and is rotatably connected. One side of the rotating rod 2 17 is fixed to the rotating shaft 15, and the other side of the rotating rod 2 17 is fixed with a gear 1 6.

[0033] Gear 6 meshes with gear 7, and the vertical centers of gear 6 and gear 7 are aligned.

[0034] Gear 6 and gear 7 are meshed together. When the motor 8 starts, gear 7 rotates, which can drive gear 6 to rotate. At the same time, the upper and lower cutting wheels 9 rotate, and the upper and lower cutting wheels 9 can cut the upper and lower sides of the steel strip body 3 simultaneously.

[0035] In this embodiment, when the stainless steel strip needs to be cut, after the motor 8 starts, gear 7 rotates, which drives gear 6 to rotate. Gear 6 drives the rotating rod 17 and the cutting wheel 9 to rotate. When the upper and lower cutting wheels 9 rotate, the steel strip body 3 is pushed between the two cutting wheels 9 for cutting. This achieves the effect of simultaneously cutting both the upper and lower sides of the stainless steel strip, improving cutting efficiency, balancing cutting force, and reducing deformation of the stainless steel strip.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
