Description

Technical Field

[0001] This invention relates to the field of grinding wheel forming technology, specifically to a multi-station automatic forming and transfer production line for ceramic bonded grinding wheels. Background Technology

[0002] The multi-station automated forming and transfer production line for ceramic bonded grinding wheels is designed for the cold pressing forming process of ceramic bonded grinding wheel blanks. It integrates a multi-station forming host, automatic quantitative material distribution, mold core placement, segmented pressurization and venting, automatic demolding, blank transfer, and mold return. It can continuously complete the entire process, including powder filling, scraping and leveling, pressure forming, blank removal and conveying, and achieve precise transfer of molds and grinding wheel blanks between stations. This reduces manual intervention, stably controls the density and dimensional consistency of blanks, and effectively improves the forming capacity and product yield of ceramic grinding wheels.

[0003] When the grinding wheel blank is removed from the pressing mold table using negative pressure adsorption, the impact generated by the start and stop of the drive column is transmitted to the fixed shell and the blank as a whole. This causes the blank to generate a lateral force relative to the fixed shell. Alternatively, if the blank accidentally scrapes against the operator during the movement, the lateral force causes the blank to move horizontally relative to the fixed shell. When the displacement exceeds the effective tolerance range of the sealing interface, gaps will appear on the sealing surface where the blank and the fixed shell are in contact, thus destroying the negative pressure seal. When the adsorption force generated by the negative pressure is insufficient to support the weight of the blank, the blank will fall off the fixed shell and onto the table, causing material scrap and potentially creating production safety hazards. Summary of the Invention

[0028] The spring is initially in a free state, and a sealing ring is provided on the outer wall of the sliding block.

[0029] Preferably, the rotating assembly includes a limiting ring rotatably connected to the outer wall of the rotating block;

[0030] The limiting ring connects four rotating blocks, which are rotatably connected to the outer wall of the fixed base.

[0032] Preferably, the elastic component includes a plurality of fixed plates fixedly connected to the side of the elastic plate near the rotating block;

[0033] The fixed plate and the rotating block work together to limit the deformation direction of the elastic plate.

[0034] There are two fixing plates, which are set in a mirror image.

[0035] Preferably, the buffer assembly includes an elastic pad fixedly connected to the side of the elastic plate away from the rotating block;

[0036] The elastic pad contacts the side wall of the billet and has a certain contact pressure with the billet.

[0037] The elastic pad material is soft rubber.

[0038] The present invention has the following beneficial effects:

[0039] (1) The present invention utilizes the evacuation of the inside of the fixed shell, the amount of gas in the space formed by the fixed shell and the blank continuously decreases, thereby forming a low-pressure space between the fixed shell and the blank, and the pressure is much lower than atmospheric pressure. Atmospheric pressure pushes the sliding block to move to the left. While the sliding block moves to the left, it drives the rotating block to rotate towards the fixed shell. At this time, the rotating block will contact the side wall of the blank, thereby applying a certain pressure to the side wall of the blank. When the blank is laterally offset relative to the fixed shell, that is, when a lateral collision or start-stop inertial impact occurs, the lateral force is all rigidly borne by the rotating block and is difficult to be transmitted to the suction cup sealing surface. Through the application of the above components, the problem of leakage between the blank and the fixed shell sealing surface caused by the movement of the drive column or the scraping of the blank is effectively alleviated, thus causing the blank to fall off.

[0040] (2) The present invention utilizes the feature that the rotating block of the above-mentioned device is close to the fixed shell. When the rotating block rotates towards the fixed shell, the elastic pad will first contact the side wall of the billet, but the pressure is small at this time. When the rotating block continues to rotate towards the fixed shell, the pressure is applied to the elastic plate, and the fixed plate is inserted into the groove of the rotating block. Thus, the deformation of the elastic plate can only bend from the thinner parts on both sides of the elastic plate, thereby reducing the distance between the elastic pad and the rotating block. At this time, the pressure can be evenly applied to the side wall of the billet through the elastic plate, which alleviates the problem of excessive stress concentration in the local area during the clamping process. In addition, the elastic pad is made of soft rubber, which reduces the indentation on the billet. At this time, the application of the above-mentioned components effectively prevents the excessive pressure concentration during the restriction process, which leads to the breakage of the billet, and at the same time improves the adaptability of the device.

[0041] (3) This invention utilizes the characteristic of the rotating block of the above-mentioned device rotating on the outer wall of the fixed seat. By setting a limiting ring, when the rotating block rotates, the rotating block will drive the limiting ring to move downward. And the four rotating blocks are connected to the same limiting ring. Thus, when one side of the rotating block rotates, the other three sides will restrict the rotating block from moving forward through the limiting ring. Thus, the four rotating blocks can approach the blank at the same speed. Moreover, the gap between the rotating block and the limiting ring is large, which prevents the problem of jamming. Through the application of the above components, the problem of uneven stress on the blank and breakage caused by one side of the rotating block contacting the blank first is effectively prevented.

[0042] (4) The present invention utilizes the feature of the above-mentioned device to extract air from the fixed shell. When the air is extracted, the airflow surges upward from the gap between the sliding plate and the billet. The gas flows out through the vent. The sum of the flow areas of the vents is less than the flow area when the air is extracted, so the airflow between the sliding plate and the billet can be extracted to form a negative pressure. When the air is filled, the airflow will first surge into the gap between the fixed shell and the sliding plate. After flowing in the gap for a period of time, the gas flows downward through the vent. Thus, the air pressure in the gap between the billet and the sliding plate gradually approaches atmospheric pressure. Through the application of the above-mentioned components, the problem of the airflow directly impacting the billet and causing surface defects in the billet during the extraction and filling of the airflow is effectively alleviated.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1, please refer to Figures 1-4 This invention relates to a multi-station automatic forming and transfer production line for ceramic binder grinding wheels, comprising a machine base 13 and a press 14. Several mixing tables 15 are fixedly connected to the top of the machine base 13, several pressing mold tables 16 are slidably connected to the top of the machine base 13, and several drive columns 17 are fixedly connected to the top of the machine base 13. The invention also includes:

[0056] Adsorption mechanism 1 is installed on the side of the drive column 17 away from the machine base 13. The adsorption mechanism 1 includes a fixed shell 111 fixedly connected to the side of the drive column 17 away from the machine base 13. A fixed ring 112 is fixedly connected to the inner wall of the fixed shell 111.

[0057] The limiting mechanism 2 is installed on the outer wall of the fixed shell 111. The limiting mechanism 2 includes several connecting holes 211 opened on the outer wall of the fixed shell 111. The inner walls of the several connecting holes 211 are slidably connected with sliding blocks 212. Several fixed seats 221 are fixedly connected to the outer wall of the fixed shell 111. Rotating blocks 222 are rotatably connected to the side of the several fixed seats 221 away from the fixed shell 111.

[0058] Pressure limiting mechanism 3 is installed on the side of rotating block 222 near fixed shell 111. Pressure limiting mechanism 3 includes an elastic plate 311 fixedly connected to the side of rotating block 222 near fixed shell 111.

[0059] The device includes two mixing tables 15 arranged in a mirror image, two pressing mold tables 16 arranged in a mirror image, two drive columns 17 arranged in a mirror image, and a fixed shell 111 with four connecting holes 211 arranged in a circular array on its outer wall. The fixed shell 111 also has four fixed seats 221 fixedly connected to its outer wall in a circular array. The operator pours the ceramic powder required for the grinding wheel into the pressing mold table 16, starts the mixing tables 15 to spread the powder evenly, and then moves the pressing mold table 16 below the press 14 for grinding wheel pressing. After pressing, the pressing mold table 16 returns to its original position, and the blank is ejected from the pressing mold table 16. The drive columns 17 are then activated to transport the blank using negative pressure adsorption. The device employs a dual-station configuration, allowing the pressing mold table 16 on one side to retract from the press 14 while the pressing mold table 16 on the other side retracts, enabling continuous pressing.

[0060] The adsorption mechanism 1 also includes:

[0061] Adhesion component 11 is installed on the outer wall of the fixed shell 111;

[0062] The movable component 12 is installed on the inner wall of the fixed shell 111;

[0063] The fixed ring 112 restricts the position of the movable component 12.

[0064] Restriction agency 2 also includes:

[0065] Sliding component 21 is installed inside the connecting hole 211;

[0066] Rotating component 22 is installed on the outer wall of rotating block 222;

[0067] Among them, the sliding component 21 drives the rotating block 222 to return to its original position.

[0068] Pressure limiting mechanism 3 also includes:

[0069] Elastic component 31 is installed on the outer wall of elastic plate 311;

[0070] The buffer assembly 32 is installed on the side of the elastic plate 311 away from the rotating block 222;

[0071] Among them, the buffer component 32 will contact the blank, and the elastic component 31 restricts the deformation direction of the elastic plate 311.

[0072] Example 2, please refer to Figures 3-8The present invention is a multi-station automatic forming and transfer production line for ceramic bonded grinding wheels. Based on the first embodiment, the bonding component 11 includes several rubber rings 113 fixedly connected to the bottom of the fixed shell 111.

[0073] Among them, the rubber ring 113 is attached to the blank and there is a certain contact pressure between them;

[0074] Two rubber rings 113 are provided, and the two rubber rings 113 are respectively adapted to the inner and outer circles of the fixing shell 111.

[0075] The active component 12 includes a sliding plate 121 that is slidably connected to the inner wall of the fixed shell 111, and the outer wall of the sliding plate 121 is provided with a plurality of ventilation holes 122.

[0076] A sealing ring is provided at the contact position between the sliding plate 121 and the fixed shell 111, and the sliding plate 121 can slide up and down on the inner wall of the fixed shell 111;

[0077] When air is being pumped out, the airflow surges upward from the gap between the sliding plate 121 and the billet, and the gas flows out through the vent 122. The sum of the flow areas of the vent 122 is less than the flow area during air pumping, so the airflow between the sliding plate 121 and the billet can be pumped away, forming a negative pressure. When air is being pumped in, the airflow will first surge into the gap between the fixed shell 111 and the sliding plate 121. After flowing in the gap for a period of time, the gas flows downward through the vent 122, so that the air pressure in the gap between the billet and the sliding plate 121 gradually approaches atmospheric pressure.

[0078] The sliding assembly 21 includes a spring 213 fixedly connected to the outer wall of the sliding block 212;

[0079] The side of spring 213 away from sliding block 212 is fixedly connected to fixed shell 111;

[0080] The spring 213 is initially in a free state, and the outer wall of the sliding block 212 is provided with a sealing ring.

[0081] The rotating assembly 22 includes a limiting ring 223 that is rotatably connected to the outer wall of the rotating block 222;

[0082] Among them, the limiting ring 223 is connected to four rotating blocks 222, and the rotating blocks 222 are rotatably connected to the outer wall of the fixed base 221;

[0083] The limiting ring 223 can restrict the four rotating blocks 222 to rotate simultaneously, and the rotation angles are the same;

[0084] When the fixed shell 111 is driven downward by the drive column 17, the rubber ring 113 will contact the blank, and there will be a certain contact pressure between the rubber ring 113 and the blank. At this time, the air inside the fixed shell 111 is evacuated, and the amount of gas in the space formed by the fixed shell 111 and the blank continuously decreases, thereby forming a low-pressure space between the fixed shell 111 and the blank, and the pressure is much lower than atmospheric pressure. Figure 7 As shown, a low-pressure space is formed on the left side of the sliding block 212, while the right side of the sliding block 212 is in the atmospheric environment. At this time, the atmospheric pressure pushes the sliding block 212 to move to the left, so that the spring 213 changes from a free state to a stretched state. While the sliding block 212 moves to the left, it drives the rotating block 222 to rotate towards the fixed shell 111. At this time, the rotating block 222 will contact the side wall of the blank, thereby applying a certain pressure to the side wall of the blank. When the blank is laterally offset relative to the fixed shell 111, that is, when a lateral collision or start-stop inertial impact occurs, the lateral force is all rigidly borne by the rotating block 222 and is difficult to be transmitted to the suction cup sealing surface.

[0085] When the rotating block 222 rotates, it will drive the limiting ring 223 to move downward. The four rotating blocks 222 are connected to the same limiting ring 223. Thus, when one rotating block 222 rotates, the other three sides will restrict the rotating block 222 from moving forward through the limiting ring 223, so that the four rotating blocks 222 can approach the blank at the same speed.

[0086] The elastic component 31 includes a plurality of fixed plates 312 fixedly connected to the side of the elastic plate 311 near the rotating block 222;

[0087] The fixed plate 312 and the rotating block 222 cooperate to limit the deformation direction of the elastic plate 311;

[0088] There are two fixing plates 312, and the two fixing plates 312 are set in a mirror image.

[0089] The buffer assembly 32 includes an elastic pad 321 fixedly connected to the side of the elastic plate 311 away from the rotating block 222;

[0090] Among them, the elastic pad 321 contacts the side wall of the billet and has a certain contact pressure with the billet;

[0091] The elastic pad 321 is made of soft rubber;

[0092] When the rotating block 222 rotates toward the fixed shell 111, the elastic pad 321 will first contact the side wall of the blank, but the pressure is relatively small at this time. When the rotating block 222 continues to rotate toward the fixed shell 111, the pressure is applied to the elastic plate 311, and the fixed plate 312 is inserted into the groove of the rotating block 222. Thus, the deformation of the elastic plate 311 can only bend from the thinner parts on both sides of the elastic plate 311, thereby reducing the distance between the elastic pad 321 and the rotating block 222. At this time, the pressure can be evenly applied to the side wall of the blank through the elastic plate 311, which alleviates the problem of excessive local stress concentration during the clamping process. In addition, the elastic pad 321 is made of soft rubber, which reduces the indentation on the blank. When pressing grinding wheel blanks of different sizes within a certain range, the elastic plate 311 can apply a certain pressure to the side wall of the blank.

[0093] One specific application of this embodiment is as follows: During use, the operator pours the ceramic powder required for the grinding wheel into the pressing mold table 16, starts the stirring table 15 to spread the powder in the pressing mold table 16, and then moves the pressing mold table 16 to the bottom of the press 14 for grinding wheel pressing. After pressing is completed, the pressing mold table 16 returns to its original position, and the blank is ejected from the pressing mold table 16. Then, the drive column 17 is started to transport the blank through negative pressure adsorption. The device adopts a dual-station setting. When the pressing mold table 16 on one side exits the press 14, the pressing mold table 16 on the other side can enter the press 14 to achieve continuous pressing.

[0094] When the grinding wheel blank is removed from the pressing mold table 16 using negative pressure adsorption, the impact generated by the start and stop of the drive column 17 is transmitted to the fixed shell 111 and the blank as a whole. This causes a lateral force to be generated on the blank relative to the fixed shell 111. Alternatively, if the blank accidentally scrapes against the operator during the movement, the lateral force causes a horizontal displacement of the blank relative to the fixed shell 111. When the displacement exceeds the effective tolerance range of the sealing interface, gaps will appear on the sealing surface where the blank and the fixed shell 111 are in contact, thus disrupting the negative pressure seal. When the adsorption force generated by the negative pressure is insufficient... Sufficient to bear the weight of the billet itself, the billet will detach from the fixed shell 111 and fall onto the table, causing material scrap and potentially posing a production safety hazard. When the fixed shell 111 is driven downward by the drive column 17, the rubber ring 113 will contact the billet, and there will be a certain contact pressure between the rubber ring 113 and the billet. At this time, the air inside the fixed shell 111 is evacuated, and the amount of gas in the space formed between the fixed shell 111 and the billet continuously decreases, thereby forming a low-pressure space between the fixed shell 111 and the billet, with a pressure much lower than atmospheric pressure. Figure 7As shown, a low-pressure space is formed on the left side of the sliding block 212, while the right side of the sliding block 212 is in the atmospheric environment. At this time, the atmospheric pressure pushes the sliding block 212 to move to the left, so that the spring 213 changes from a free state to a stretched state. While the sliding block 212 moves to the left, it drives the rotating block 222 to rotate towards the fixed shell 111. At this time, the rotating block 222 will contact the side wall of the blank, thereby applying a certain pressure to the side wall of the blank. When the blank is laterally offset relative to the fixed shell 111, that is, when a lateral collision or start-stop inertial impact occurs, the lateral force is all rigidly borne by the rotating block 222 and is difficult to be transmitted to the suction cup sealing surface. Through the application of the above components, the problem of leakage between the blank and the sealing surface of the fixed shell 111 caused by the movement of the drive column 17 or the scraping of the blank is effectively alleviated, thus preventing the blank from falling off.

[0095] Taking advantage of the fact that the rotating block 222 is close to the fixed shell 111, when the rotating block 222 applies pressure to the billet, it causes concentrated lateral extrusion force on the billet. This results in delamination of the billet during the restraint process. When the rotating block 222 rotates towards the fixed shell 111, the elastic pad 321 will initially contact the side wall of the billet, but the pressure is relatively low at this point. As the rotating block 222 continues to rotate towards the fixed shell 111, pressure is applied to the elastic plate 311, and the fixed plate 312 is engaged in the groove of the rotating block 222. Therefore, the deformation of the elastic plate 311 is limited. The elastic plate 311 can be bent at the thinner sides, thereby reducing the distance between the elastic pad 321 and the rotating block 222. At this time, the pressure can be evenly applied to the side wall of the blank through the elastic plate 311, which can alleviate the problem of excessive local stress concentration during the clamping process. In addition, the elastic pad 321 is made of soft rubber, which reduces the indentation on the blank. When pressing grinding wheel blanks of different sizes within a certain range, the elastic plate 311 can apply a certain pressure to the side wall of the blank. At this time, the application of the above components effectively prevents excessive pressure concentration during the restriction process, which could lead to the breakage of the blank, and at the same time improves the adaptability of the device.

[0096] Utilizing the characteristic of the rotating block 222 rotating on the outer wall of the fixed seat 221, when negative pressure is applied, the synchronization of the four rotating blocks 222 is insufficient, resulting in one side of the fixed seat 221 contacting the billet first. This leads to uneven clamping and localized stress concentration, causing fragmentation on one side of the billet. By setting a limiting ring 223, when the rotating block 222 rotates, it drives the limiting ring 223 to move downwards. Since all four rotating blocks 222 are connected to the same limiting ring 223, when one side of the rotating block 222 rotates, the other three sides are restricted from moving ahead by the limiting ring 223. This allows all four rotating blocks 222 to approach the billet at the same speed. Furthermore, the large gap between the rotating block 222 and the limiting ring 223 prevents jamming. Through the application of the above components, the problem of uneven stress and fragmentation of the billet caused by one side of the rotating block 222 contacting the billet first is effectively prevented.

[0097] Utilizing the air extraction feature of the aforementioned device from the fixed housing 111, during both extraction and inflation, the airflow emerges from a single hole at a relatively high speed, directly impacting the billet and causing erosion marks and surface defects. During extraction, the airflow surges upwards from the gap between the sliding plate 121 and the billet, flowing out through the vent 122. The sum of the flow areas of the vent 122 is less than the flow area during extraction, allowing the airflow between the sliding plate 121 and the billet to be extracted, creating a negative pressure. During inflation, the airflow first flows into the gap between the fixed housing 111 and the sliding plate 121, flowing there for a period before flowing downwards through the vent 122. This gradually reduces the air pressure between the billet and the sliding plate 121 to near atmospheric pressure. The application of these components effectively mitigates the problem of direct airflow impact on the billet during extraction and inflation, preventing surface defects.
