Description

Technical Field

[0001] This utility model relates to the field of strip edge grinding technology, and in particular to a hot-rolled strip edge trimming mechanism. Background Technology

[0002] After steel is hot-rolled into strip, the edges of the strip are cut as needed. After cutting, burrs will appear on the edges of the strip, which not only affects the overall appearance of the strip but also makes it inconvenient for subsequent use. Therefore, a deburring mechanism is needed to grind the cut edges of the strip. Currently, the deburring mechanisms commonly found on the market all have rotating grinding rollers on both sides of the strip. When the strip is transported, the grinding rollers grind its edges. However, in existing mechanisms, the installation position of the grinding rollers is fixed.

[0003] In the current production process, the specifications of steel strip often need to be flexibly adjusted to meet diverse order demands, with the strip width being the most frequent change. Since the grinding mechanism is usually installed on both sides of the conveyor, when the strip width is adjusted, the grinding mechanism on both sides needs to be disassembled and adjusted accordingly, which is quite cumbersome. Furthermore, during the grinding process, the removed burrs turn into fine residue that scatters. Due to the lack of an effective collection and guidance mechanism, this residue easily accumulates randomly above the conveyor. As the residue continues to accumulate, it will seriously pollute the operating environment of the conveyor, making the working area full of debris and dust, thus reducing the environmental quality of the workshop. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in adjusting the grinding mechanism according to the width of the strip, and the pollution caused by the accumulation of burr residue in the workshop environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hot-rolled strip edge trimming mechanism, including a grinding table, with symmetrically distributed conveying mechanisms on the front and back of the grinding table, and symmetrically distributed moving grooves at the upper end of the grinding table.

[0006] The grinding table is equipped with an adjustment mechanism, which includes a two-way lead screw. The two ends of the two-way lead screw are rotatably connected to the inner walls of both sides of the grinding table through bearings. A worm gear is fixedly sleeved on the outside of the two-way lead screw.

[0007] The external thread of the bidirectional lead screw is connected to symmetrically distributed threaded blocks. The upper end of the threaded blocks is fixedly connected to a movable support block. The upper end of the movable support block passes through the movable groove and extends to the upper end of the grinding table. The upper end of the movable support block is fixedly connected to a mounting plate.

[0008] Optionally, a servo motor is fixedly installed on the inner bottom wall of the grinding table, and a worm gear is fixedly installed on the output shaft of the servo motor through a coupling. The outer surface of the worm gear meshes with the tooth surface of the worm wheel.

[0009] Optionally, an arc-shaped collection cover is fixedly connected to the upper end of the mounting plate, and a drive motor is fixedly installed on the upper end of the arc-shaped collection cover. The output shaft of the drive motor is fixedly installed with a rotating shaft through a coupling.

[0010] Optionally, one end of the rotating shaft passes through and extends into the interior of the arc-shaped collection hood, and a grinding wheel is fixedly sleeved on the outside of one end of the rotating shaft. A manifold box is fixedly connected to the upper end of the mounting plate.

[0011] Optionally, a negative pressure fan is fixedly installed on one side of the manifold, a movable filter frame is installed inside the manifold, and a first duct is fixedly connected to the other side of the manifold.

[0012] Optionally, one end of the first conduit is fixedly connected to the outside of the arc-shaped collection cover, and the lower end of the manifold is fixedly connected to the second conduit.

[0013] Optionally, one end of the second conduit passes through the mounting plate and the movable support block and extends to the lower end of the arc-shaped collection hood, and one end of the second conduit is fixedly connected to the fan-shaped collection block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention achieves automated adjustment of the grinding wheel's position through an adjustment mechanism, which not only reduces manual labor but also improves operational efficiency, thereby meeting the grinding needs of strips of different widths. Furthermore, the negative pressure is used to collect the fine residue from grinding burrs, greatly improving the working environment of the workshop. Attached Figure Description

[0022] Example

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a hot-rolled strip edge trimming mechanism, including a grinding table 1. The front and back of the grinding table 1 are provided with symmetrically distributed conveying mechanisms 2. This pair of conveying mechanisms 2 are like two precise tracks, which can stably and efficiently convey the hot-rolled strip to the grinding area, ensuring the smooth operation of the strip throughout the trimming process. The upper end of the grinding table 1 is provided with symmetrically distributed moving grooves 3.

[0024] The grinding table 1 is equipped with an adjustment mechanism, which includes a two-way lead screw 4. The two ends of the two-way lead screw 4 are rotatably connected to the inner walls of both sides of the grinding table 1 through bearings. A worm gear 41 is fixedly sleeved on the outside of the two-way lead screw 4. This connection method ensures both the smoothness of the lead screw rotation and its stability under high-intensity operation.

[0025] The external thread of the bidirectional lead screw 4 is connected to symmetrically distributed threaded blocks 42. The upper end of the threaded block 42 is fixedly connected to a movable support block 43. The upper end of the movable support block 43 passes through the movable groove 3 and extends to the upper end of the grinding table 1. The movable groove 3 provides a stable guide for the movable support block 43 here, preventing it from deviating during movement and ensuring the accuracy of subsequent grinding operations.

[0026] The upper end of the movable support block 43 is fixedly connected to the mounting plate 44, and the inner bottom wall of the grinding table 1 is fixedly installed with a servo motor 45. The servo motor 45 serves as the power source of the adjustment mechanism and has high-precision speed control and torque output capabilities.

[0027] The output shaft of the servo motor 45 is fixedly mounted with a worm gear 46 via a coupling. The outer surface of the worm gear 46 meshes with the tooth surface of the worm wheel 41. When the servo motor 45 is started, the rotational motion is converted into the precise linear motion of the bidirectional lead screw 4.

[0028] An arc-shaped collection cover 47 is fixedly connected to the upper end of the mounting plate 44. The arc-shaped collection cover 47 adopts an arc-shaped design that conforms to the principle of aerodynamics. During the grinding process, it can gather the fine burrs and residues generated by grinding to the greatest extent and prevent them from scattering and polluting the workshop environment.

[0029] A drive motor 48 is fixedly installed at the upper end of the arc-shaped collection cover 47. The output shaft of the drive motor 48 is fixedly installed with a rotating shaft 49 through a coupling. One end of the rotating shaft 49 passes through and extends into the interior of the arc-shaped collection cover 47. A grinding wheel 410 is fixedly sleeved on the outside of one end of the rotating shaft 49. The grinding wheel 410 is made of a high-hardness, wear-resistant material, and its grit size and hardness are optimized and matched according to the material characteristics of the hot-rolled strip to ensure efficient removal of burrs on the edge of the strip while ensuring the quality of the edge of the strip after grinding.

[0030] The upper end of the mounting plate 44 is fixedly connected to the manifold box 411, and a negative pressure fan 412 is fixedly installed on one side of the manifold box 411. The negative pressure fan 412 has a strong negative pressure suction capacity and can form a stable negative pressure environment inside the manifold box 411.

[0031] The manifold 411 is equipped with a movable filter frame 413 inside. The other side of the manifold 411 is fixedly connected to the first conduit 414. The movable filter frame 413 adopts an easy-to-disassemble design, which makes it convenient for operators to clean the debris accumulated on the filter screen regularly. The pore size of the internal filter screen is carefully selected, which can effectively intercept the fine burrs generated by grinding, and ensure smooth airflow to maintain the working efficiency of the negative pressure fan.

[0032] One end of the first conduit 414 is fixedly connected to the outside of the arc-shaped collection hood 47. This connection method ensures that the debris adsorbed by negative pressure inside the arc-shaped collection hood 47 can smoothly enter the first conduit 414. The lower end of the manifold 411 is fixedly connected to the second conduit 415.

[0033] One end of the second conduit 415 passes through the mounting plate 44 and the movable support block 43 and extends to the lower end of the arc-shaped collection hood 47. One end of the second conduit 415 is fixedly connected to a fan-shaped collection block 416. The fan-shaped collection block 416 is custom-designed according to the lower contour of the arc-shaped collection hood 47, and its interior is inclined. This design allows debris falling to the lower end of the arc-shaped collection hood 47 to be smoothly sucked into the manifold 411 under the dual action of gravity and negative pressure of the second conduit 415, which greatly improves the comprehensiveness and thoroughness of debris collection.

[0034] The working process of this utility model:

[0035] Step 1: The strip is conveyed to the grinding table 1 by one of the conveying mechanisms 2. The servo motor 45 is started according to the width of the strip. The servo motor 45 drives the worm gear 46 to rotate. The rotation of the worm gear 46 drives the bidirectional lead screw 4 to rotate through the meshing worm wheel 41. The rotation of the bidirectional lead screw 4 drives the moving support block 43 to move through the threaded block 42. The moving support block 43 stabilizes the two mounting plates 44 relative to each other through the limiting of the moving groove 3, thereby automatically adjusting the position of the grinding wheel 410.

[0036] Step 2: Start the negative pressure fan 412 and drive motor 48. Drive motor 48 drives grinding wheel 410 to rotate via shaft 49. The rotation of grinding wheel 410 grinds the burrs on the plate belt. The fine burr debris is adsorbed by the negative pressure inside arc-shaped collection cover 47, and then transported to the inside of manifold 411 through first conduit 414. Finally, it is intercepted by the filter screen in movable filter frame 413. Some of the falling debris is received by fan-shaped collection block 416. The inside of fan-shaped collection block 416 is inclined, which makes it easier for debris to be sucked into manifold 411 through negative pressure via second conduit 415.

[0037] Step 3: Operators can periodically remove the movable filter screen using the handle at the top to facilitate cleaning of debris and reuse. Additionally, the back of the manifold 411 has an inspection door, allowing for regular cleaning and maintenance of the interior of the manifold 411.

[0038] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
