Description

Technical Field

[0001] The utility model relates to the technical field of grinding tool preparation, in particular to a grinding wheel pressing device. Background Art

[0002] The production process of grinding wheels is mainly divided into four steps: batching, mixing, molding and sintering. In the molding step, the prepared raw materials need to be placed in the mold, and then a hydraulic press is used to press the raw materials in the mold to press the loose raw materials into grinding wheel blanks, which are then dried and fired.

[0003] The existing pressing tools have the following defects in actual use: when the hydraulic press is pressing the raw materials, due to the high pressure, some raw materials will adhere to the lower end surface of the hydraulic press plate when they are pulled out from the mold after pressing. This will easily cause the grinding wheel flatness to decrease during the next pressing, thereby affecting the overall strength of the grinding wheel. Therefore, the raw materials adhered to the lower end surface of the pressing plate need to be cleaned. The existing cleaning method is to manually scrape them off with a scraper and clean the raw materials that have fallen on the placement platform. The operation is cumbersome and time-consuming.

[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 4It is given, including an L-shaped fixed plate 1, on which a placing plate 2 is provided, on which a mold cylinder 3 with an upper and lower axial direction and an opening facing upward is placed, the upper end of the placing plate 2 is rotatably connected to a rotating shaft 4 located on the right side of the mold cylinder 3 and in the upper and lower axial direction, the rotating shaft 4 is provided with a left and right support plate 5, and the left and right sides of the support plate 5 are respectively slidably connected with a sliding column 6 in the upper and lower axial direction, the lower end of the sliding column 6 is coaxially provided with a lower pressure plate 7 that can be inserted into the mold cylinder 3, the upper end of the sliding column 6 is coaxially provided with an upper pressure plate 8, the upper end of the placing plate 2 is provided with a scraper 9 located on the right side of the rotating shaft 4 and can contact with the lower end surface of the lower pressure plate 7, a hydraulic press 10 is provided on the upper side of the fixed plate 1, a hydraulic cylinder 11 is provided on the hydraulic press 10, a hydraulic column 12 is coaxially slidably connected in the hydraulic cylinder 11, a hydraulic plate 13 that can contact with the upper pressure plate 8 is coaxially provided at the lower end of the hydraulic column 12, and a controller 14 is provided at the lower end of the placing plate 2.

[0017] In order to facilitate the resetting of the lower pressure plate 7 , a compression spring 15 is sleeved on the slide column 6 and is located between the upper pressure plate 8 and the support plate 5 .

[0018] In order to rotate the rotating shaft 4 , a vertical plate is provided on the fixed plate 1 , a motor 16 is provided on the upper end of the vertical plate, and the lower end of the rotating shaft 4 penetrates the placement plate 2 and is coaxially fixedly connected with the motor 16 .

[0019] In order to facilitate the collection of the scraped raw materials, a drop groove 17 located in front of the scraper 9 is opened at the upper end of the placement plate 2, and a collection box 18 is placed on the lower side of the fixed plate 1, which is located directly below the drop groove 17 and has an opening facing upward.

[0020] In order to facilitate the movement of the fixing plate 1 , a plurality of universal wheels distributed in a rectangular shape are provided at the lower end of the fixing plate 1 .

[0021] In order to facilitate the fixing and limiting of the mold, a limiting hole is coaxially provided at the lower end of the mold cylinder 3, and a limiting column 19 is provided at the upper end of the placement plate 2 to be inserted into the limiting hole.

[0022] In order to facilitate pushing the fixing plate 1, a push handle is provided at the left end of the placing plate 2.

[0023] When the utility model is used, firstly, the stirred raw materials are poured into the mold barrel 3, and then the hydraulic press 10 is turned on. The hydraulic press 10 drives the hydraulic column 12 to move downward in the hydraulic cylinder 11, and then drives the hydraulic plate 13 to move downward. After the hydraulic plate 13 moves downward for a distance, it contacts the upper pressing plate 8 and drives the upper pressing plate 8 on the left side to move downward. The upper pressing plate 8 on the left side drives the lower pressing plate 7 to move downward through the sliding column 6. After the lower pressing plate 7 moves downward for a distance, it is inserted into the mold barrel 3 and squeezes the raw materials therein downward, so as to squeeze the loose raw materials tightly and shape the raw materials.

[0024] After the pressing is completed, the hydraulic column 12 moves upward, thereby driving the hydraulic plate 13 to move upward. At this time, the upward restoring force of the compression spring 15 drives the lower pressing plate 7 on the left to move upward. The lower pressing plate 7 on the left moves upward for a distance and then is pulled out of the mold tube 3. At this time, there are a lot of raw materials stuck to the lower end of the lower pressing plate 7 on the left. After the lower pressing plate 7 moves upward to the initial position, the controller 14 controls the motor 16 to start, and the motor 16 drives the rotating shaft 4 to rotate counterclockwise. The rotating shaft 4 drives the support plate 5 and the sliding column 6 thereon to rotate counterclockwise, thereby driving the upper pressing plates 8 and the lower pressing plates 7 on the left and right sides to rotate. After rotating a certain angle, the lower pressing plate 7 with the raw materials stuck on the lower end rotates until it contacts the scraper 9, and the scraper 9 scrapes off the raw materials stuck thereon.

[0025] The scraped raw material falls into the collecting box 18 through the dropping groove 17. At this time, the rotating shaft 4 rotates 180 degrees counterclockwise, and the controller 14 controls the motor 16 to automatically close. At this time, the lower pressing plate 7 originally located on the right side rotates to the left side and is coaxial with the mold cylinder 3. At the same time, the lower pressing plate 7 with raw material attached to the lower end is scraped off half by the scraper 9 and stays on the right side. At this time, the pressed mold can be taken out and the formed grinding wheel can be taken out, and then the raw material is poured again, and the hydraulic press 10 is reopened. The hydraulic plate 13 moves downward again and compacts the raw material in the mold cylinder 3 again. After molding, the hydraulic plate 13 rises again, and then the controller 14 controls the motor 16 to start again. The motor 16 drives the rotating shaft 4 to rotate 180 degrees counterclockwise again, scrapes off the remaining part of the lower pressing plate 7 with raw material originally attached, and rotates to the left side, and repeats this process. After pressing and molding, the motor 16 is started to rotate the lower pressing plate 7. While rotating, the raw material attached to the lower pressing plate 7 is scraped off, and the hanging raw material is collected to prevent scattering.

[0026] Compared with the prior art, the utility model has the following beneficial effects: the upper pressure plate, lower pressure plate, rotating shaft, etc. are provided, which can realize compacting the raw materials in the mold barrel, pressing the originally loose raw materials into a grinding wheel embryo, and can automatically scrape off and collect the raw materials adhering to the lower pressure plate to prevent affecting the pressing of the next grinding wheel. Compared with traditional manual scraping, the operation is simple and time-saving and labor-saving. The structure is simple, the concept is novel, the use is convenient, and the practicability is strong.

[0027] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
