Technical Field

[0001] This application relates to the field of steel plate processing technology, and in particular to a steel plate grinding equipment. Background Technology

[0002] Steel plates are flat steel products made by pouring molten steel, cooling it, and then pressing it into shape.

[0003] During the steel plate production process, burrs exist on the surface of the steel plate. In related technologies, operators hold an angle grinder and place the grinding disc of the angle grinder close to the burr area on the surface of the steel plate. The high-speed rotation of the angle grinder drives the grinding disc to grind the burrs and manually remove the burrs from the surface of the steel plate.

[0004] The above-mentioned method of manually grinding and removing burrs from steel plates by operators using handheld angle grinders relies on manual processing of burrs on each steel plate, which is time-consuming and labor-intensive, resulting in low steel plate production efficiency and making it difficult to meet the needs of large-scale steel plate production. Summary of the Invention

[0005] To address the problem of manual burr removal from steel plates using handheld angle grinders, which is time-consuming, labor-intensive, and inefficient, hindering large-scale steel plate production, this application provides a steel plate grinding device with the following technical solution: It includes a base, on which the steel plate to be ground is mounted. A mounting frame is mounted on the base, and a support frame is slidably connected to the mounting frame.

The moving device includes a moving cylinder disposed on the support frame, and a moving rod is provided at the output end of the moving cylinder. The end of the moving rod opposite to the moving cylinder is fixedly disposed on the mounting frame.

[0010] In one specific implementation, the mounting frame is provided with a support rod, and a support block that matches the support rod is slidably connected to the support rod, the support block being disposed on the support frame.

[0011] In one specific implementation, a plurality of rotating rollers are rotatably connected to the base, and the steel plate to be ground is mounted on the plurality of rotating rollers.

[0012] In one specific implementation, the base is provided with a guide plate, the steel plate to be ground is placed on the guide plate, and the end of the guide plate opposite to the rotating roller is provided with a guide slope.

[0013] In one specific implementation scheme, the support frame is provided with a connecting frame, the grinding device is disposed on the connecting frame, the connecting frame has an oblong hole, a mounting bolt passes through the oblong hole, and the support frame has a mounting groove on the surface facing the base that matches the mounting bolt, and the mounting bolt is threaded into the mounting groove.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0021] This application discloses a steel plate grinding device.

[0022] Reference Figure 1 and Figure 2 The steel plate grinding equipment includes a base 1. The steel plate to be ground is supported on the base 1 by its own weight. A mounting frame 2 is installed on the base 1. A support frame 3 is slidably connected to the mounting frame 2. A grinding device for grinding the steel plate is provided on the support frame 3. The grinding device is an angle grinder 18. Other grinding equipment in the prior art can also be used, and there is no limitation. In this embodiment, five angle grinders 18 are evenly distributed on the support frame 3 as an example. A lifting device for driving the mounting frame 2 to rise and fall is provided on the base 1.

[0023] Therefore, when steel plates need to be ground, the steel plate is placed on the base 1, the lifting device is activated, the lifting device drives the mounting frame 2 to descend, and the grinding unit on the mounting frame 2 descends accordingly until the grinding unit contacts the surface of the steel plate. The angle grinder 18 is then activated to grind the surface of the steel plate, eliminating the tedious process of manually removing burrs one by one. This significantly improves the efficiency of steel plate grinding, reduces labor costs, saves time and effort, meets the needs of large-scale steel plate production, and improves the production efficiency of steel plates.

[0024] Reference Figure 1 and Figure 2 A number of rotating rollers 13 are rotatably connected to the base 1, arranged in an array. The steel plate to be ground is placed on the rotating rollers 13. When the operator places the steel plate on the base 1, the rotating rollers 13 reduce the friction between the steel plate and the base 1, allowing the operator to easily push the steel plate to the appropriate position, facilitating the loading of the steel plate. The base 1 is equipped with opposing limiting plates. The steel plate placed on the rotating rollers 13 is positioned between the two limiting plates. The limiting plates limit the position of the steel plate, reducing the possibility of the steel plate deviating from the base 1 in case of accidents, thus improving the safety and stability of the steel plate grinding process.

[0025] Reference Figure 1 and Figure 2A guide plate 14 is bolted to the base 1. The steel plate to be ground is placed on the guide plate 14. A guide slope 15 is provided at the end of the guide plate 14 facing away from the rotating roller 13. The ground steel plate can be easily unloaded from the guide slope 15 of the guide plate 14. The guide slope 15 reduces the possibility of the sharp edge of the guide plate 14 damaging the bottom of the steel plate. In this embodiment, a mounting groove is opened on the end face of the guide plate 14 facing the steel plate. An electromagnet matching the size of the mounting groove is installed in the mounting groove. When the angle grinder 18 starts to grind the steel plate, the electromagnet is activated to attract the steel plate onto the guide plate 14, reducing the possibility of the steel plate shifting during the grinding process and improving the grinding effect of the steel plate.

[0026] Reference Figure 1 and Figure 2 A connecting frame 16 is mounted on the support frame 3, and the angle grinder 18 is mounted on the connecting frame 16. The connecting frame 16 has a slotted hole through which a mounting bolt passes. The support frame 3 has a mounting groove on its surface facing the base 1, matching the size of the mounting bolt. The mounting bolt is threaded into the mounting groove. The operator can remove the connecting frame 16 from the support frame 3 by unscrewing the bolt, thus making the angle grinder 18 detachable. The slotted hole facilitates fine-tuning of the connecting frame 16's position on the support frame 3, improving the flexibility of the angle grinder 18's position. Five protective covers 17 are mounted on the connecting frame 16, with the grinding discs of the five angle grinders 18 partially located on the inner edge of each of the five protective covers 17. The protective covers 17 can also be directly mounted on the angle grinder 18; this is not a limitation. In this embodiment, the side of the rotating roller 13 away from the angle grinder 18 is the feeding end of the steel plate for the operator, and the side of the rotating roller 13 close to the angle grinder 18 is the unloading end of the steel plate after grinding. The opening of the protective cover 17 is set towards the unloading end. The protective cover 17 plays a blocking role for the grinding debris, greatly reducing the possibility of iron filings splashing onto the operator, and providing a safe operating environment for the operator.

[0027] Reference Figure 1 and Figure 3 The lifting device includes a lifting cylinder 4 vertically mounted on a base 1, and a mounting frame 2 mounted on the output end of the lifting cylinder 4. The lifting cylinder 4 can be a lifting air cylinder or a hydraulic cylinder; in this embodiment, a hydraulic cylinder is used as an example. A lifting rod 5 is mounted on the output end of the lifting cylinder 4, and a support seat 6 is bolted to the base 1. The support seat 6 has a support hole 8 that matches the size of the lifting rod 5. The lifting rod 5 passes through the support hole 8 and contacts the hole wall. The support hole 8 limits the movement direction of the lifting rod 5, reducing the possibility of positional deviation during the lifting process of the mounting frame 2 driven by the lifting rod 5, and improving the stability of the mounting frame 2 during the lifting process.

[0028] Reference Figure 1 and Figure 3A placement groove is provided on the wall of the support hole 8, and a support sleeve 7 is installed in the placement groove. The lifting rod 5 passes through the support sleeve 7 and contacts the inner wall of the support sleeve 7. The support sleeve 7 provides support for the lifting rod 5 while reducing the direct friction between the lifting rod 5 and the support hole 8, thereby reducing the wear of the lifting rod 5 and the support hole 8 and extending their service life.

[0029] Reference Figure 1 and Figure 2 The mounting frame 2 is equipped with a moving device that drives the support frame 3 to move. The moving device includes a moving cylinder 9 horizontally mounted on the support frame 3. The moving cylinder 9 can be a push-pull cylinder or a push-pull hydraulic cylinder. In this embodiment, a push-pull hydraulic cylinder is used as an example. A moving rod 10 is installed at the output end of the moving cylinder 9. The end of the moving rod 10 away from the moving cylinder 9 is fixedly mounted on the mounting frame 2. Therefore, when the moving cylinder 9 is activated, since the end of the moving rod 10 away from the moving cylinder 9 is fixed on the mounting frame 2, the moving cylinder 9 extends and retracts horizontally along the moving rod 10, causing the support frame 3 connected to the moving cylinder 9 to slide, thereby realizing the adjustable position of the angle grinder 18, which is convenient for grinding different positions of the steel plate. Two support rods 11 are installed on the mounting frame 2, and the moving cylinder 9 is located between the two support rods 11. Support blocks 12 that match the size of the support rods 11 are slidably connected to the support rods 11. The support blocks 12 are mounted on the support frame 3, and the operator can set the number and position of the support blocks 12 according to the actual situation on site. The support rod 11 limits the movement of the support block 12, thereby improving the stability of the support frame 3 during the sliding process.

[0030] The implementation principle of this application embodiment is as follows: When steel plates need to be ground, the operator places the steel plate on the rotating roller 13 and pushes the steel plate below the angle grinder 18. The lifting cylinder 4 is activated, causing the lifting rod 5 and the mounting frame 2 to descend, thus lowering the angle grinder 18 on the support frame 3 until the grinding disc of the angle grinder 18 contacts the surface of the steel plate. The angle grinder 18 is then activated to grind the surface of the steel plate. When different positions of the steel plate need to be ground, the moving cylinder 9 is activated. Since the end of the moving rod 10 opposite to the moving cylinder 9 is fixed on the mounting frame 2, the moving cylinder 9 extends and retracts horizontally along the moving rod 10, causing the support frame 3 connected to the moving cylinder 9 to slide. This allows for adjustment of the grinding position of the angle grinder 18. Simultaneously, the operator can also push the steel plate to adjust the grinding position, eliminating the tedious process of manually removing burrs one by one. This significantly improves the efficiency of steel plate grinding, reduces labor costs, saves time and effort, meets the needs of large-scale steel plate production, and improves the production efficiency of steel plates.
