[0002] A grinding wheel, also known as a vitrified abrasive tool, is a vitrified abrasive tool in which ordinary abrasives are solidified into a certain shape (mostly circular with a through hole in the center) by a binder and has a certain strength. It generally consists of abrasives, a binder, and pores. These three parts are often referred to as the three elements of a vitrified abrasive tool. In the production and manufacturing process of grinding wheels, mechanical equipment is often used to press the mixed abrasives and binder into shape. Therefore, a wheel pressing device for grinding wheel production is required.

[0003] The prior art discloses a pressing and forming device for grinding wheel manufacturing with the publication number: CN217532005U, which includes a bottom block.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a wheel pressing device for grinding wheel production, which has the following beneficial effects:

[0017] (1). The utility model is provided with a loading and unloading plate, a cleaning box, a brush plate and brush strips. During use, workers can introduce an appropriate amount of grinding wheel production uniform material into the mold block fixedly installed on the top surface of the loading and unloading plate. Then, the workers can start the servo motor installed on one side of the workbench through the control panel to drive the driving lead screw installed in the installation chute to rotate. Since the first installation sliders symmetrically and fixedly installed on the bottom surface of the loading and unloading plate are clamped and installed in the installation chute, and the first lead screw sleeve fixedly installed in the first installation slider is internally threaded with the driving lead screw, the rotation of the driving lead screw can drive the loading and unloading plate together with the mold block to move into the inner cavity of the protection box through the feeding and discharging port, and the mold block is moved directly below the pressing plate. On the other hand, a limiting port is opened on the side wall of the protection box, and the cleaning box is clamped and installed in the limiting port. A connecting plate is fixedly welded to one side of the bottom surface of the cleaning box. At the same time, the second installation slider fixedly installed on the bottom surface of the connecting plate is also clamped in the installation chute, and the second lead screw sleeve fixedly installed in the second installation slider is also internally threaded with the driving lead screw. Therefore, the rotation of the driving lead screw can also drive the connecting plate together with the cleaning box to slide along the limiting port. When the mold block moves directly below the pressing plate, the cleaning box moves out of the inner cavity of the protection box. At this time, the worker can start the hydraulic press through the control panel to drive the pressing plate to descend to realize the pressing production of the grinding wheel. After the pressing is completed, the hydraulic press drives the pressing plate to reset to the initial position. Then, the servo motor drives the driving lead screw to rotate in the reverse direction. At this time, the loading and unloading plate together with the mold block moves out of the inner cavity of the protection box, and the cleaning box moves into the inner cavity of the protection box again. A plurality of installation chucks are symmetrically opened on the cleaning box, and the brush plates are symmetrically clamped and installed in the installation chucks. Brush strips are fixedly installed on the top surface of the brush plates. Therefore, when the loading and unloading plate is loading and unloading, it can drive the cleaning box together with the brush plates and brush strips to move. The top surface of the moving brush strip will abut against the lower surface of the reset pressing plate, so that the material adhered to the lower surface of the pressing plate can be cleaned and swept off by using the brush strip. A collection box is clamped and installed in the cleaning box, and the collection box can be used to centrally collect the cleaned materials, which is convenient for subsequent recycling and reuse, avoiding the waste of materials. Furthermore, a wheel pressing device for grinding wheel production can use the loading and unloading mechanism of the mold block to drive the brush strip to clean the abrasive adhered to the bottom surface of the pressing plate. It is not only simple in structure and more convenient to use, but also reduces the manufacturing cost of the device and the power consumption during use, and has stronger practicability.

[0018] (2) The utility model is provided with an installation slot, a brush plate, a fixing pin and a fixing hole. As mentioned above, the materials adhered to the lower surface of the pressure plate can be cleaned by using the multiple brush plates and brush strips. However, after long-term use, the brush strips will also cause certain wear. When replacing the brush strips, the worker can manually push and push the push block to compress the return spring connected to the side wall of one side of the push block. The other side of the push block is fixedly installed with a fixing pin, and the fixing pin is inserted into the fixing holes symmetrically opened at both ends of the brush plate.
