Description

Technical Field

[0001] The utility model belongs to the technical field of hot-rolled strip processing, in particular to a novel hot-rolled strip edge grinding device. Background Art

[0002] Hot-rolled strip is a steel product produced through the hot rolling process. Hot-rolled strip usually uses steel billets as raw materials. After being heated at high temperature, it is deformed into strip steel with a certain thickness, width and length through the strong pressure of the rolling mill. Hot-rolled strip has good mechanical properties, high strength, good toughness, and can withstand large loads. Its surface quality is relatively rough, but it can be improved through subsequent processing. Hot-rolled strip is widely used in many fields such as construction, machinery manufacturing, automobile manufacturing, shipbuilding, etc., and is an indispensable and important material in industrial production.

[0003] The prior art includes a utility model with publication number CN211839697U, which discloses a device for deburring the edge of a hot-rolled strip. The patent adopts a deburring roller (1) comprising an upper roller and a lower roller arranged in parallel. The roller surface of the deburring roller (1) is elliptical, and the diameter in the middle is larger than the diameter at both ends. The deburring roller (1) has an axial hole (5), and a roller shaft is provided in the axial hole (5). The roller shaft is provided with a bearing and a bearing seat. The lower roller of the deburring roller (1) is fixed on a frame (9), and the upper roller of the deburring roller (1) is connected to the piston rod of a cylinder (6), and the cylinder body of the cylinder (6) is fixed on the frame (9). The beneficial effects of this utility model are: it can play a certain auxiliary clamping role in the case of poor plate shape, prevent the problem of poor quality of edge burr removal caused by edge jumping, and avoid the damage to the bearing caused by the large amount of heat generated in the production process due to the entire roller surface contacting the strip, while eliminating the hidden danger of iron filings being brought in and causing indentation defects, and solve the problem that when the plane contact is running at high speed, the deburring roller will generate a lot of heat while removing burrs, which will cause the connecting bearing to be easily damaged and stuck, and at the same time the steel roller contacts the surface of the strip, and there is a risk of iron filings being brought in, which will cause the hidden danger of indentation.

[0004] In the process of processing the hot-rolled strip with the help of the edge grinding device, its grinding structure contacts the hot-rolled strip through the same area. During operation, since the grinding structure uses the same area for a long time, grooves will appear on the surface of the grinding structure, causing the grinding effect to deteriorate. At the same time, the remaining areas of the grinding structure are not consumed, so the grinding structure needs to be replaced, resulting in a relatively wasteful problem of the grinding structure. Utility Model Content

[0005] In order to solve the defect of the existing hot-rolled strip edge grinding device that the grinding mechanism uses the same area for grinding for a long time during use, resulting in ineffective utilization of other areas and causing waste, the utility model provides a new hot-rolled strip edge grinding device, which can adjust the grinding position of the grinding mechanism as needed to maximize the utilization of the entire area of ​​the grinding mechanism.

[0006] The utility model is realized through the following technical solutions:

[0009] The auxiliary components include an assembly frame, a guide wheel, a pressure plate, a servo motor, a grinding cylinder and a support frame;

[0010] The assembly frame is fixedly arranged on the surface of the table, and a placement slot is opened in the middle along the vertical direction and penetrates the frame body; a support frame is fixed to the bottom of the placement slot, and a servo motor is installed on the top of the placement slot through the mounting frame, the output end of the servo motor is connected to the rotating shaft, and the other end of the rotating shaft is connected to the support frame through a bearing; a grinding cylinder is sleeved on the shaft body of the rotating shaft and fastened by bolts;

[0011] The guide wheels are arranged on the surface of the assembly rack on both sides of the placement groove and are perpendicular to the assembly rack; a pressing plate is provided above the guide wheels and is movably connected to the surface of the assembly rack.

[0012] The working principle of this utility model is as follows:

[0013] When processing the hot-rolled strip, the hot-rolled strip is placed in the conveying area between the active roller and the driven roller, the DC motor is turned on to drive the active roller to rotate, and the hot-rolled strip is conveyed to the table, and then the hot-rolled strip is placed above the guide wheel. The hot-rolled strip is pressed by the pressure plate to prevent the hot-rolled strip from deviating from the guide wheel during the conveying process; then the servo motor is turned on to drive the rotating shaft to drive the grinding drum to rotate to grind the edge of the hot-rolled strip. After the grinding drum has worked for a period of time, the bolt is loosened and the position of the grinding drum on the rotating shaft is adjusted. After tightening the bolt, the grinding work is continued, so that the working area of ​​the grinding drum is fully utilized.

[0014] As a further improvement of the present invention, sliding grooves are provided at both ends of the assembly frame in the vertical direction, and threaded rods are provided in the sliding grooves; a slider is provided in the middle of one side of the pressure plate and is threadedly connected to the threaded rod.

[0015] The pressing plate is movably connected to the sliding groove and is threadedly connected to the threaded rod. When the position of the pressing plate needs to be adjusted, it is only necessary to rotate the threaded rod, which is convenient for adjusting the position of the pressing plate according to hot-rolled strips of different sizes.

[0016] As a further improvement of the present invention, the assembly frame is provided with guide grooves on both sides of the sliding groove; and guide blocks are provided at both ends of one side of the pressure plate to match the guide grooves.

[0017] On the one hand, the guide groove facilitates the adjustment of the position of the pressing plate, and on the other hand, it can stabilize the pressing plate to prevent the edge pressing end from tilting too much due to the conveying of the hot-rolled strip.

[0018] As a further improvement of the present invention, one end of the guide wheel is movably connected to a placement plate, and the other end is movably connected to a limit plate; the placement plate is fixed to the surface of the assembly frame.

[0019] The guide wheel is indirectly connected to the assembly frame to avoid wear of the assembly frame due to long-term rotation, and it is also convenient to replace the guide wheel.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The grinding wheel of the utility model can be adjusted on the rotating shaft as needed, which avoids using the same area of ​​the grinding wheel to grind the edge of the hot-rolled strip for a long time, thereby improving the utilization rate of the grinding wheel.

[0022] 2. The pressure plate of the present application can be adjusted in position according to the size of the hot-rolled strip, which increases the scope of application of the present invention. At the same time, the pressure plate adopts a threaded rod for position adjustment, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
