[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 by a binder and have a certain strength. Most of them are circular with a through hole in the center. Since the grinding wheel rotates at a high speed during use, it can be used for rough grinding, semi-finishing grinding, and finishing grinding of the outer circle, inner circle, plane, and various profiles of metal or non-metal workpieces, as well as grooving and cutting. It has become the most widely used and most widely used abrasive tool.

[0003] In the existing grinding wheel pressing device, after the grinding wheel raw materials are put into the lower mold, the upper mold is driven to move and close with the lower mold to realize the pressing and forming of the raw materials. Since the raw materials are put into the lower mold from a single angle, the raw materials are not uniform in the lower mold at the beginning, and there will be a phenomenon of local accumulation. As a result, when the upper mold and the lower mold are pressed and formed, the density of each part of the grinding wheel is inconsistent, resulting in uneven strength and unqualified quality of each part of the grinding wheel, increasing the production cost of producers. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a grinding wheel pressing device, which is used to solve the technical problem that the current pressing device directly presses and forms after putting raw materials into the lower mold, which is likely to cause inconsistent density and unqualified quality of each part of the grinding wheel.

[0005] To achieve the above purpose, the technical solution of the utility model is: a grinding wheel pressing device, which includes a frame, a lower mold, an upper mold, a scraping component, and a driving component arranged on the frame. The scraping component includes a turntable driven by a motor to rotate and a scraping plate eccentrically connected to the turntable. When the turntable rotates coaxially with the lower mold, the scraping plate is driven to rotate around the central axis of the lower mold to realize the scraping of the raw materials in the lower mold; the driving component includes a bracket slidably connected to the frame, a linkage plate, and a telescopic driving member connecting the bracket and the linkage plate. The telescopic driving member is used to drive the linkage plate to lift and lower. The upper mold and the motor are respectively connected to both ends of the linkage plate; the bracket slides horizontally on the frame to enable the turntable or the upper mold to be in a coaxial position above the lower mold.

[0006] Preferably, the scraping plate adopts a conical cross-section style, and the scraping plate gradually thickens from the lower end to the upper end.

[0007] Preferably, the telescopic driving member adopts a hydraulic cylinder.

[0008] Preferably, the bracket is a gantry, and the lower end of the gantry is slidably connected to a slide rail provided on the frame.

[0009] Preferably, a demoulding bottom plate, a grinding wheel hole avoidance shaft arranged on the demoulding bottom plate, and a lifting drive member for driving the demoulding bottom plate to rise and fall are arranged in the lower mold.

[0010] Preferably, the lifting drive member is a hydraulic cylinder.

[0011] Preferably, the bottom of the upper mold is provided with an avoidance hole that cooperates with the avoidance axis of the grinding wheel hole.

[0012] The beneficial effects of adopting the technical solution of the utility model are:

[0013] The utility model comprises an upper mold and a scraping plate which are integrally connected by a linkage plate. The linkage plate is driven to rise and fall by a telescopic driving member. The telescopic driving member is connected to a bracket which is slidably connected to a frame. The scraping plate assembly comprises a turntable and a scraping plate eccentrically connected to the turntable. The turntable is driven to rotate by a motor. The bracket drives the upper mold and the scraping plate assembly to move and makes the turntable above the lower mold and coaxial with the lower mold. At this time, the turntable rotates under the drive of the motor, and the turntable drives the scraping plate to rotate around the central axis of the lower mold. After the raw material is put into the lower mold, the bracket is moved horizontally so that the turntable is above the lower mold and coaxial with the lower mold, and the telescopic drive is started. The driving part makes the scraper plate extend into the lower mold, and the motor is started to drive the turntable to rotate. The turntable drives the scraper plate to rotate around the central axis of the lower mold to scrape the raw material in the lower mold to ensure that the raw material in each part of the lower mold is relatively uniform and the density of the pressed grinding wheel is consistent at each part; after the grinding wheel raw material is scraped flat, the telescopic driving part contracts to drive the scraper plate to withdraw from the lower mold, and the mobile bracket drives the upper mold to be above the lower mold and coaxial with the lower mold. The telescopic driving part extends to drive the upper mold downward into the lower mold to press the raw material, so that the density of the formed grinding wheel is consistent at each part, ensuring the quality compliance rate of the produced grinding wheel.

[0021] The specific embodiments are as follows:

[0022] Embodiment 1, as Figures 1-3 shown, a grinding wheel pressing device, the pressing device includes a frame 1, a lower mold 2, an upper mold 3, a leveling assembly 4 and a drive assembly 5. The frame 1 includes a support plate 11 and legs 12. The lower mold 2 is fixedly connected to the support plate 11 and is used to receive the grinding wheel raw material.

[0023] The leveling assembly 4 includes a motor 41, a turntable 42 and a leveling plate 43. The turntable 42 is connected to the shaft of the motor 41 and is driven to rotate by the motor 41. The leveling plate 43 is connected to the lower side of the turntable 42 through a connecting rod and is eccentrically arranged. When the turntable 42 is above the lower mold 2 and coaxial with the lower mold, it rotates under the drive of the motor 41, and the turntable 42 drives the leveling plate to rotate around the central axis of the lower mold 2 to realize the leveling of the raw material in the lower mold 2.

[0024] The driving assembly 5 includes a bracket 51, a linkage plate 52, and a telescopic driving member 53. The bracket 51 is slidably connected to the support plate 11 and can move horizontally. The telescopic driving member 53 is connected to the bracket 51, and the linkage plate 52 is connected to the telescopic end of the telescopic driving member 53 to drive the linkage plate 52 to move up and down. In this embodiment, the telescopic driving member 53 is a hydraulic cylinder.

[0025] The upper mold 3 is connected to one end of the linkage plate 52 through a connecting rod, and the motor 41 is fixedly connected to the other end of the linkage plate 52 to ensure that the telescopic driving member 53 can drive the upper mold 3 and the leveling assembly 4 to move up and down synchronously. The bracket 51 slides horizontally on the support plate 11, driving the turntable 42 or the upper mold 3 to be above the lower mold 2 and in a position coaxial with the lower mold 2.

[0026] Further, the leveling plate 43 is in a tapered cross-sectional shape, that is, the leveling plate 43 gradually thickens from bottom to top. In this way, the inclined surface has a guiding effect when leveling the raw material, preventing the raw material from piling up upward and crossing the leveling plate 43 during the leveling process.

[0027] Further, the bracket 51 is a gantry, and the lower end of the gantry is slidably connected to the slide rails 111 provided at both ends of the support plate 11.

[0028] Further, a demolding bottom plate 22, a grinding wheel hole avoidance shaft 21, and a lifting driving member 23 are provided in the lower mold 2. The outer diameter of the demolding bottom plate 22 is the same as the inner diameter of the lower mold 2, and it is sleeved inside the lower mold 2. The grinding wheel hole avoidance shaft 21 is vertically connected to the demolding bottom plate 22 and is coaxial with the lower mold 2. The lifting driving member 23 is a hydraulic cylinder, fixed to the bottom of the support plate 11 through a connecting frame 24. The telescopic end of the hydraulic cylinder passes through the support plate 11 and is connected to the bottom of the demolding bottom plate 22. After the upper mold 3 and the lower mold 2 press and form the grinding wheel, the lifting driving member 23 is activated to push the demolding bottom plate 22 upward, and the grinding wheel is exposed upward from the lower mold 2, facilitating the removal of the grinding wheel.

[0029] Further, an avoidance hole 31 is provided at the bottom of the upper mold 3, and the avoidance hole cooperates with the grinding wheel hole avoidance shaft 21 to facilitate the upper mold 3 to enter the lower mold 2 to press the raw material and form a grinding wheel.

[0030] In other embodiments, the lower mold, the upper mold, and the leveling plate are all detachably connected to facilitate replacement according to the preparation of grinding wheels of different models, improving flexibility and applicability. Other structures will not be elaborated here.

[0031] The above has described the present utility model by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
