Description

Technical Field

[0001] This invention relates to the field of abrasive processing technology, and in particular to an abrasive production line and a production method. Background Technology

[0002] Abrasives are high-efficiency precision grinding tools widely used in industries such as stone, ceramics, glass, and semiconductors. They are primarily used for grinding and polishing workpieces and are indispensable key consumables in related manufacturing fields. With the rapid development of high-end manufacturing industries and the widespread application of automated processing equipment, the demand for abrasive products in downstream markets continues to grow significantly, while also placing higher demands on the capacity for large-scale, mass production of abrasives.

[0003] Existing mold forming production lines have a relatively simple configuration, typically with only one hot press forming machine per line. The hot press forming process itself requires a fixed period of pressure holding and vulcanization. During this waiting period, the entire production line is idle and cannot operate continuously. This single-line, single-machine configuration, constrained by the inherent waiting time of hot press forming, results in low line utilization, disjointed production cycles, and difficulty in increasing overall capacity, failing to meet the industry's demand for large-scale, high-efficiency mold production.

[0004] Therefore, there is an urgent need for a grinding wheel production line with higher production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a mold production line and production method to solve the problems existing in the prior art. By setting two molding stations in parallel, the production line stagnation caused by waiting time at a single molding station is effectively avoided, thereby improving the efficiency of mold production.

[0006] To achieve the above objectives, the present invention provides the following solution: This invention provides a mold production line, comprising: a control system, a conveying mechanism, and sequentially arranged assembly stations, feeding stations, scraping stations, cap-laying stations, and forming stations; wherein, the assembly station is equipped with a mold-loading machine for assembling mold rings and mold bases; the feeding station is equipped with a feeding machine for feeding material into a target area; the scraping station is equipped with a scraping machine for leveling the raw material; the cap-laying station is equipped with a cap-laying machine for assembling mold caps onto the mold ring; at least two forming stations are provided, arranged in parallel downstream of the cap-laying station; each forming station is equipped with a forming machine for hot pressing; the conveying mechanism can sequentially convey molds from the assembly station to the feeding station, the scraping station, the cap-laying station, and the forming station; and the control system can control the conveying mechanism to cyclically and alternately convey molds to the forming station.

Both the feeding station and the scraping station are located in the pushing direction of the second pushing mechanism.

[0011] As one embodiment, the conveying mechanism further includes a third pushing mechanism, the pushing direction of the third pushing mechanism being perpendicular to the pushing direction of the second pushing mechanism and opposite to the pushing direction of the first pushing mechanism, and the cap-laying station being located in the pushing direction of the third pushing mechanism.

[0012] As one embodiment, the conveying mechanism further includes multiple fourth pushing mechanisms.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] The purpose of this invention is to provide a mold production line and production method to solve the problems existing in the prior art. Through the control system, molds can be cyclically and alternately conveyed to multiple forming stations, thereby improving the production efficiency of the mold production line.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 Please refer to Figure 1This embodiment provides a mold production line, including: a control system 1, a conveying mechanism, and an assembly station 2, a feeding station 3, a scraping station 4, a cap-laying station 5, and a forming station 6 arranged sequentially; wherein, the assembly station 2 is equipped with a mold mounting machine for assembling the mold ring and the mold base, the feeding station 3 is equipped with a feeding machine for feeding material to the target area, the scraping station 4 is equipped with a scraping machine for leveling the raw material, the cap-laying station 5 is equipped with a cap-laying machine for assembling the mold cap onto the mold ring, and at least two forming stations 6 are arranged in parallel downstream of the cap-laying station 5. The forming station 6 is equipped with a forming machine for hot pressing to hot press the raw material in the mold into a mold. The conveying mechanism can transport the mold from the assembly station 2 to the feeding station 3, the scraping station 4, the cap-laying station 5, and the forming station 6 in sequence, and the control system 1 can control the conveying mechanism to cyclically and alternately transport the mold to the forming station 6. Its working principle is as follows: the mold assembly machine can assemble the pre-prepared mold ring and mold base together. The assembled mold ring and mold base have a space for receiving materials. The conveying mechanism transports the mold ring and mold base to the feeding station 3. The feeding machine can feed materials into the mold ring according to preset parameters. After entering the space between the mold ring and mold base, the raw material forms a mound shape, smaller at the top and larger at the bottom. When it reaches the scraping station 4, the scraper can level the raw material. The conveying mechanism continues to transport the mold ring and mold base downstream to the capping station 5. The capping machine can place the pre-prepared mold cap on top of the mold ring, thus forming a complete set of molds. The control system 1 can control the entire set... The mold is conveyed to forming station 6 for hot pressing, thus completing the forming of the mold. Simultaneously, the control system 1 controls the conveying mechanism to cyclically and alternately convey molds to the parallel forming stations 6. That is, the first set of molds is conveyed to the first forming station 6, the second set to the second forming station 6, the third set back to the first forming station 6, and so on. This method staggers the hot pressing waiting cycles of each forming station 6, effectively avoiding production line stagnation caused by waiting time at a single forming station 6, achieving continuous and uninterrupted operation of the production line, and improving the equipment utilization rate and overall production efficiency of the mold production line. It is understood that the mold includes a mold ring, mold base, and mold cover.

[0024] In one embodiment, the pre-prepared mold ring and mold base are placed within the operating range of the mold loading machine, and the pre-prepared mold cover is placed within the operating range of the cover placing machine.

[0025] In one embodiment, the conveying mechanism, molding machine, feeding machine, scraping machine, capping machine, and forming machine are all connected to the control system 1. The control system 1 can control the start and stop of each piece of equipment, thereby enabling fully automated production.

[0026] In one embodiment, a demolding station 7 is located downstream of the molding station 6. The demolding station 7 is equipped with a demolding machine and a sorting machine 8. A conveying mechanism can transport the mold from the molding station 6 to the demolding station 7. The demolding machine can demold the mold, and the sorting machine 8 can sort the mold. The demolding machine can demold the mold after one hot pressing of the mold to separate the mold ring, mold bottom, and mold cover from the mold. The sorting machine 8 can sort out the mold ring, mold bottom, and mold cover and transport them to a designated location. Furthermore, the sorting machine 8 can transport the mold bottom to the assembly station 2, transport the mold cover to the operating range of the cover placement machine, and transport the mold to the mold storage area via a robotic arm. The demolding station 7 is located within the coverage area of ​​the robotic arm of the mold assembly machine. The mold assembly machine can grab the mold ring left at the demolding station 7 and transport it to the assembly station 2 for assembly of the mold ring and mold bottom. This method enables the molds to be reused within the production line. Compared to the previous method of first demolding the molds and then transporting them to assembly station 2, it saves transportation time, achieves automatic reuse of the molds, improves production efficiency, and reduces the labor intensity of workers.

[0027] In one embodiment, the assembly station 2, feeding station 3, scraping station 4, cap placement station 5, molding station 6, and demolding station 7 are arranged in a ring. This arrangement shortens the distance between the molding station 6 and the assembly station 2; that is, the demolding station 7 is located downstream of the molding station 6, and the assembly station 2 is located downstream of the demolding station 7. This reduces the distance and time it takes for the mold to circulate throughout the production line, thereby improving the production efficiency of the production line.

[0028] In one embodiment, a third sliding platform 16 is provided between the demolding station 7 and the cap placement station 5.

[0029] In one embodiment, arranged in a ring, a certain distance is left between the sorting machine 8 at the demolding station 7 and the cap-laying station 5. A third sliding platform 16 is positioned between the sorting machine 8 and the cap-laying station 5. The sorting machine 8 can transport the mold caps to the third sliding platform 16 via a robotic arm. The third sliding platform 16 can slide between the sorting machine 8 and the cap-laying station 5, and can enter the operating range of both the sorting machine 8 and the cap-laying machine, respectively, so that the cap-laying machine can install the mold caps onto the mold ring. This method can reduce the overall design length of the robotic arm of the sorting machine 8, avoid the problem of easy interference during the operation of the robotic arm, and reduce the control difficulty of the robotic arm.

[0030] In one embodiment, the conveying mechanism includes a first pushing mechanism 9, and the demolding station 7 is located on the pushing path of the first pushing mechanism 9; the first pushing mechanism 9 can convey the mold formed by hot pressing by the molding mechanism to the demolding station 7.

[0031] In one embodiment, the mold production line further includes a first sliding platform 10. Forming stations 6 are arranged side-by-side, with the first sliding platform 10 slidably positioned downstream of the forming stations 6. The sliding direction of the first sliding platform 10 is parallel to the line connecting two adjacent forming stations 6. A first pushing mechanism 9 is mounted on the first sliding platform 10. The first sliding platform 10 is connected to the control system 1. When a mold is delivered from the corresponding forming station 6, the first sliding platform 10 can move downstream of the corresponding forming station 6 to support the delivered mold and carry it to the upstream side of the demolding station 7. At this time, the first pushing mechanism 9 can push the mold located on the first sliding platform 10 to the demolding station 7 for demolding. This allows multiple molds that have undergone hot pressing to be orderly transported to the upstream end of the production line for recycling, improving the production efficiency of the production line.

[0032] In one embodiment, the conveying mechanism further includes a second pushing mechanism 11, which is disposed between the assembly station 2 and the feeding station 3. The pushing direction of the second pushing mechanism 11 is perpendicular to the pushing direction of the first pushing mechanism 9. The feeding station 3 and the scraping station 4 are both located in the pushing direction of the second pushing mechanism 11. The first pushing mechanism 9 can push the mold on the assembly station 2 onto the pushing path of the second pushing mechanism 11, and the second pushing mechanism 11 can push the mold to the feeding station 3 to feed material into the space between the mold ring and the mold bottom.

[0033] In one embodiment, the conveying mechanism further includes a third pushing mechanism 12. The pushing direction of the third pushing mechanism 12 is perpendicular to the pushing direction of the second pushing mechanism 11, and opposite to the pushing direction of the first pushing mechanism 9. The cap-laying station 5 is located in the pushing direction of the third pushing mechanism 12. The third pushing mechanism 12 is located downstream of the scraping station 4. The second pushing mechanism 11 can push the mold that has completed scraping onto the pushing path of the third pushing mechanism 12, and the third pushing mechanism 12 can push the mold to the cap-laying station 5.

[0034] In one embodiment, the second pushing mechanism 11 can directly push the completed scraping mold onto the pushing path of the third pushing mechanism 12, or indirectly push the previous set of molds onto the pushing path of the third pushing mechanism 12 by pushing the latter set of molds to the scraping station 4.

[0035] In one embodiment, the conveying mechanism further includes a plurality of fourth pushing mechanisms 13. The pushing direction of the fourth pushing mechanism 13 is perpendicular to the pushing direction of the third pushing mechanism 12, and the pushing direction of the fourth pushing mechanism 13 is opposite to the pushing direction of the second pushing mechanism 11. The number of fourth pushing mechanisms 13 matches the number of forming stations 6. The forming stations 6 are arranged side by side, and the fourth pushing mechanism 13 is located on the upstream side of the forming station 6. The third pushing mechanism 12 can push the mold that has completed the capping operation onto the pushing path of the fourth pushing mechanism 13, so that the mold can be pushed to the forming station 6 for hot pressing through the fourth pushing mechanism 13.

[0036] In one embodiment, the mold production line further includes a second sliding platform 14, which is located downstream of the cap-laying station 5. The sliding direction of the second sliding platform 14 is parallel to the line connecting two adjacent forming stations 6. A fourth pushing mechanism 13 is located on the side of the second sliding platform 14 away from the forming station 6. After the mold completes the cap-laying operation, the second sliding platform 14 can move to the downstream side of the cap-laying station 5 to support the mold conveyed from the cap-laying station 5 and convey the mold to the upstream side of the target forming station 6 by sliding. The fourth pushing mechanism 13 then actuates to push the mold to the forming station 6, thereby realizing the orderly conveying of multiple molds that have completed the cap-laying operation to the forming station 6 and improving the production efficiency of the production line.

[0037] In one embodiment, the mold production line further includes a feeding station 15, which is located between the cover feeding station 5 and the scraping station 4. The feeding station 15 is equipped with a feeding machine for feeding the connector into the mold. The connector enters the hot pressing station along with the mold, thereby realizing the hot pressing of the connector and the mold into a whole, so as to facilitate the connection and disassembly of the mold with the target part during use.

[0038] In one embodiment, the connector is a Velcro strap.

[0039] In one embodiment, the connector is a mushroom-shaped hook and loop fastener or a single plastic hook.

[0040] In one embodiment, both the material feeding station 15 and the cover feeding station 5 are located in the pushing direction of the third pushing mechanism 12.

[0041] In one embodiment, the first pushing mechanism 9, the second pushing mechanism 11, the third pushing mechanism 12, and the fourth pushing mechanism 13 can all be servo electric cylinders, servo hydraulic cylinders, or pneumatic cylinders.

[0042] In one embodiment, the first sliding platform 10, the second sliding platform 14, and the third sliding platform 16 can all be motor-driven sliding platforms, hydraulically driven sliding platforms, or cylinder-driven sliding platforms.

[0043] In one embodiment, the conveying mechanism is a known conveying mechanism such as a flexible chain turning conveyor or an arc belt turning conveyor. The conveying mechanism connects the assembly station 2, the feeding station 3, the scraping station 4, the unloading station 15, the capping station 5, the forming station 6, and the demolding station 7, and is capable of conveying the mold from the demolding station 7 to the assembly station 2. Correspondingly, the start and stop of the conveying mechanism are matched with the working rhythm of each station. For example, when feeding, the conveying mechanism is in a stationary state, and when it is necessary to convey the mold that has completed feeding to the next station, the conveying mechanism starts to operate.

[0044] In one embodiment, the molding machine can be a flat vulcanizing machine or a hot press molding machine.

[0045] In one embodiment, four sets of molds can be arranged side by side at each workstation.

[0046] In one embodiment, the mold production line includes four forming stations 6, which are arranged side by side downstream of the cap-laying station 5. The working time of the forming machine in each forming station 6 is fixed, and this working time ensures that the production line completes at least one demolding, assembly, feeding, scraping, loading, and cap-laying operation. After the initial debugging is completed, the program is stored in the control system 1. When the production line is started, the control system 1 defaults to first pushing the mold to the forming station 6 closest to the cap-laying station 5, and then pushing the mold to the downstream forming stations 6 in sequence. During this process, the forming stations 6 that are pushed into the molds sequentially start the hot pressing forming operation, thereby completing the continuous production of molds.

[0047] Example 2 This embodiment provides a method for producing abrasives, including: Step S1: The mold assembly machine assembles the mold at assembly station 2 using the mold base and mold ring; Step S2: The feeding machine feeds material into the mold that has been conveyed to the feeding station 3; Step S3: The scraper scrapes the mold that has been conveyed to scraping station 4; Step S4: The cap-laying machine assembles the mold cap onto the mold ring; Step S5: The conveying mechanism alternately transports the mold to the forming station 6; Step S6: The molding machine performs hot pressing molding.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
