Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, and in particular to a steel processing burr grinding device. Background Technology

[0002] In the steel processing industry, after processes such as laser cutting, punching, and welding, burrs and flash are easily formed on the surface of steel. These burrs not only affect the appearance quality of the steel, but also reduce the accuracy of subsequent assembly, and may even scratch operators during handling and use. Therefore, burr removal is a key subsequent process in steel processing.

[0003] Currently, most steel burr grinding equipment commonly used in the industry adopts a single grinding wheel structure, which can only adapt to steel of a single width. If different specifications of workpieces need to be processed, the equipment parts need to be disassembled and adjusted, which is cumbersome and time-consuming, and has extremely poor adaptability. Secondly, although some devices are equipped with multiple grinding wheels, each grinding wheel is mostly driven independently. This can easily lead to uneven force on the steel due to inconsistent speeds, resulting in surface scratches, deformation and other problems, affecting the processing quality. Thirdly, a large amount of metal dust and debris are generated during the grinding process. The dust collection structure of existing devices is mostly a simple exhaust design with low dust capture rate. A large amount of dust diffuses into the working environment, polluting the air and easily causing health problems such as pneumoconiosis for operators. Utility Model Content

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a steel processing burr grinding device, including a grinding table 1, a filter plate 6 is provided on the surface of the grinding table 1, a grinding component 4 is provided above the filter plate 6, and a dust collection component 5 is provided below the filter plate 6.

[0030] The polishing assembly 4 includes a support frame 401, which is fixedly connected to the surface of the polishing table 1. Both ends of the support frame 401 are provided with drivers 402. The output end of the driver 402 passes through the support frame 401 and is fixedly connected to an active polishing wheel 403. Both sides of the active polishing wheel 403 are provided with driven polishing wheels 404. The tops of the driven polishing wheels 404 and the active polishing wheels 403 are fixedly connected with gears 413. The surface of the gears 413 is meshed with a toothed belt 405.

[0031] Specifically, the support frame 401 has two sliding grooves 406 on its surface. The inner walls of the two sliding grooves 406 are slidably connected to limit plates 407. Two movable rods 408 are rotatably connected to one side of the limit plates 407. The other end of the movable rods 408 is rotatably connected to a sliding block 409. The surface of the sliding block 409 is threaded with a bidirectional screw 410. Both ends of the bidirectional screw 410 are fixedly connected to a fixing plate 411. The lower end of the fixing plate 411 is fixedly connected to the central shaft partition of the grinding table 1. The lower ends of the active grinding wheel 403 and the driven grinding wheel 404 are rotatably connected to the surface of the grinding table 1. The driver 402 is a servo motor. One end of the bidirectional screw 410 is provided with a throttle 412. The throttle 412 is fixedly connected to the bidirectional screw 410. The active grinding wheel 403 has two gears 413 on its top. The two gears 413 are connected to the gears 413 on the top of the driven grinding wheel 404 through a toothed belt 405.

[0032] Furthermore, the two sliding grooves 406 on the surface of the support frame 401 form a sliding fit with the limiting plate 407. The movable rod 408 rotatably connected to one side of the limiting plate 407 is linked with the sliding block 409. The sliding block 409 is threaded onto the bidirectional screw 410. Both ends of the bidirectional screw 410 are fixed to the central shaft partition of the grinding table 1 via the fixing plate 411. The handle 412 at one end can drive the screw to rotate. Rotating the handle 412 synchronously adjusts the distance between the sliding blocks 409 on both sides. The movable rod 408 pushes the limiting plate 407 to move along the slide groove 406, achieving precise positioning of steel of different widths. This effectively improves the device's adaptability to processing workpieces of multiple specifications, solving the limitation of traditional devices that can only adapt to a single specification of workpiece. The lower ends of both the active grinding wheel 403 and the driven grinding wheel 404 are rotatably connected to the surface of the grinding table 1, ensuring the stability of the grinding structure. The double gear 413 at the top of the active grinding wheel 403 meshes with the gear 413 at the top of the driven grinding wheel 404 through the toothed belt 405. With the help of the servo motors at both ends of the support frame 401, the rotation speed of each grinding wheel is consistent, avoiding the problem of uneven force distribution caused by single-wheel drive. This significantly improves the grinding accuracy and surface flatness of the steel and reduces workpiece scratches.

[0033] Example 2

[0034] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The dust collection component 5 includes a dust collection hood 501, which is located inside the grinding table 1. The lower end of the dust collection hood 501 is fixedly connected to an air guide pipe 502, and the other end of the air guide pipe 502 is fixedly connected to an exhaust fan 503. The output end of the exhaust fan 503 is fixedly connected to an air supply pipe 504, and the other end of the air supply pipe 504 is fixedly connected to a collection box 505.

[0035] Specifically, the collection box 505 is equipped with a filter bag for collecting particles in the smoke and dust. A protective frame 2 is fixedly connected to the surface of the grinding table 1. A protective cover 3 is hinged to the surface of the protective frame 2. A cabinet door 7 is hinged to the front of the grinding table 1. A handle 8 is fixedly connected to the surface of the cabinet door 7.

[0036] Furthermore, the dust hood 501 is located inside the grinding table 1, which can capture metal dust and debris generated during grinding at close range. The exhaust fan 503 provides stable negative pressure, so that the dust is accurately transported to the collection box 505 through the air guide pipe 502 and the air delivery pipe 504. With the efficient interception of dust particles by the filter bag inside the box, the dust can be effectively prevented from spreading to the operating environment, solving the problem of dust pollution in traditional grinding, ensuring a clean working environment and the health of personnel. The protective frame 2 on the surface of the grinding table 1 and the hinged protective cover 3 form a closed working space, which not only prevents dust from overflowing during grinding, but also prevents personnel from directly contacting high-speed rotating parts, improving operational safety. The hinged cabinet door 7 and the surface handle 8 on the front of the grinding table 1 make it easy for operators to quickly open the cabinet door 7 to clean or replace the filter bag inside the collection box 505.

[0037] Working principle: The grinding table 1 is the basic carrier. The filter plate 6 on its surface connects the grinding area with the dust collection component 5 below. During operation, according to the width of the steel to be processed, the handle 412 at one end of the bidirectional screw 410 is rotated to drive the bidirectional screw 410 to rotate around the fixed plate 411. This causes the sliding block 409 with threaded sleeve to adjust the spacing synchronously, which in turn drives the movable rod 408 to push the limiting plate 407 to move along the sliding groove 406 on the surface of the support frame 401, thus completing the precise limiting of the steel and adapting to the processing needs of workpieces of different specifications. Then, the driver 402 at both ends of the support frame 401 is activated. Its output end drives the active grinding wheel 403 to rotate. The two gears 413 on the top of the active grinding wheel 403 mesh with the gears 413 on the top of the driven grinding wheels 404 on both sides through the toothed belt 405, driving the driven grinding wheels 403 to rotate synchronously, forming a multi-wheel rotation. The collaborative grinding structure performs rough edge grinding on the steel after it has been positioned, and the grinding wheels rotate at the same speed to avoid scratches on the workpiece caused by uneven force, thereby improving grinding accuracy and surface flatness. Metal dust and debris generated during the grinding process fall into the grinding table 1 through the filter plate 6. The exhaust fan 503 of the dust collection component 5 provides a stable negative pressure, so that the dust is captured by the dust collection hood 501 and transported to the collection box 505 through the air guide pipe 502 and the air delivery pipe 504. The filter bag in the box effectively intercepts the dust particles and prevents the dust from spreading. At the same time, the protective frame 2 on the surface of the grinding table 1 and the hinged protective cover 3 form a closed space to prevent dust from overflowing and personnel from coming into contact with high-speed components, thus ensuring operational safety. After grinding is completed, the cabinet door can be opened by pulling the handle 8 of the cabinet door 7 on the front of the grinding table 1, and the filter bag in the collection box 505 can be cleaned or replaced to maintain the continuous working performance of the device.
