Description

Technical Field

[0001] This utility model relates to the field of grinding wheel production equipment, and in particular to a pressing and molding device for ceramic grinding wheel production. Background Technology

[0002] Ceramic-bonded diamond grinding wheels have advantages such as high strength, good heat resistance, sharp cutting edge, high grinding efficiency, low heat generation and clogging during grinding, and low thermal expansion. The production process of ceramic grinding wheels includes: batching, mixing, molding, drying, firing, processing, inspection, and packaging. Among these, molding and firing are the key steps that determine the quality of ceramic grinding wheels. Ceramic grinding wheels that have not been fired after molding are relatively fragile and are easily broken due to impacts during the unloading process from the pressing equipment. Therefore, it is necessary to design a pressing and molding device for ceramic grinding wheel production that reduces impacts during the unloading process and improves the yield of finished ceramic grinding wheels. Summary of the Invention

[0003] The purpose of this invention is to provide a pressing and molding device for the production of ceramic grinding wheels, which has the advantages of reducing bumps and collisions during the feeding process and improving the yield of finished ceramic grinding wheels.

[0004] The technical solution adopted is as follows:

[0005] A pressing and forming device for producing ceramic grinding wheels includes a frame, a mounting plate rotatably mounted on the frame, six support arms evenly spaced on the mounting plate, and a mold at the end of each support arm. A material feeding unit, a mesh placement unit, a trademark placement unit, a perforated ring placement unit, a pressing unit, and a feeding unit are evenly spaced on the outer side of the frame. The feeding unit includes a lifting frame, a drive shaft vertically rotatable on the lifting frame, a reciprocating rotation mechanism connected to the drive shaft on the lifting frame, a disc at the lower end of the drive shaft, two vertical shafts evenly spaced at the lower end of the disc, and a pneumatic suction cup at the lower end of each vertical shaft. A lifting platform is located at the lower end of the lifting frame, and a limit rod is vertically mounted on the lifting frame below the lifting platform. The lifting platform has through holes for the limit rods to pass through, and the lifting platform corresponds vertically to the disc.

[0006] Preferably, the frame is provided with a drive mechanism, which includes a motor and a reducer. The reducer includes an input shaft and an output shaft. The input shaft is connected to the motor, and the output shaft is provided with a drive gear. A driven gear ring is coaxially provided on the disc, and the driven gear ring meshes with the drive gear.

[0007] Preferably, the side of the disk is provided with a protective cover that covers the driven gear ring and the drive gear.

[0008] Preferably, the lifting platform includes a base plate and a top plate, and a plurality of vertically extending electric telescopic rods are fixedly installed between the base plate and the top plate.

[0009] Preferably, the frame is equipped with an encoder connected to a drive gear, and the frame is equipped with a controller connected to the encoder and the lifting platform.

[0010] Compared to existing technologies, the advantages are:

[0011] During material feeding, the lifting platform is raised to a height close to the support arm of the top plate. This reduces the height difference when the pneumatic suction cup is placed on the lifting platform, thus reducing the risk of the newly pressed and unfired grinding wheels breaking due to impacts and improving the yield of resin grinding wheels. As the number of vertical grinding wheels placed on the lifting platform increases, the lifting platform slowly descends, keeping the height difference between the uppermost grinding wheel on the lifting platform and the support arm constant.

[0016] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0017] Example 1: A pressing and forming device for producing ceramic grinding wheels includes a frame 1, a mounting plate 2 rotatably mounted on the frame 1, the mounting plate 2 rotating on the frame 1, six support arms 3 evenly spaced on the mounting plate 2, the included angle between adjacent support arms 3 is 60 degrees, and a mold 6 is provided at the end of each support arm 3. A material feeding unit 7, a mesh placement unit 8, a trademark placement unit 9, a hole ring placement unit 10, a pressing unit 11, and a feeding unit are evenly spaced on the outside of the frame 1.

[0018] The six support arms 3 of the mounting plate 2 correspond to the fabric unit 7, the mesh placement unit 8, the trademark placement unit 9, the hole ring placement unit 10, the pressing unit 11, and the unloading unit, respectively. At the same time, they perform fabrication, mesh placement, trademark placement, hole ring placement, pressing, and unloading operations on the molds 6 on different support arms 3.

[0019] The unloading unit includes a lifting frame 12, which is positioned above the support arm 3 and does not interfere with the movement of the support arm 3. The lifting frame 12 is vertically rotatable and has a drive shaft 13. The lifting frame 12 is equipped with a reciprocating rotation mechanism 14 connected to the drive shaft 13. The reciprocating rotation mechanism 14 controls the drive shaft 13 to rotate 180 degrees forward and then 180 degrees backward to reset. A disc 15 is provided at the lower end of the drive shaft 13. Two vertical shafts 16 are evenly spaced at the lower end of the disc 15. A pneumatic suction cup 17 is provided at the lower end of each vertical shaft 16. The pneumatic suction cup 17 is existing technology and will not be described in detail here. The pneumatic suction cup 17 is connected to an external air supply mechanism and control mechanism through a pipe. The pneumatic suction cup 17 is used to hold the pressed ceramic grinding wheel inside the mold 6.

[0020] A lifting platform is provided at the lower end of the lifting frame 12. A limit rod 21 is vertically provided on the lifting frame 12 below the lifting platform. The lifting platform is provided with a through hole 22 for the limit rod 21 to pass through. The lifting platform corresponds vertically to the disc 15. After the pneumatic suction cup 17 picks up the resin grinding wheel, it rotates 180 degrees through the disc 15 to correspond vertically to the lifting platform. Then the pneumatic suction cup 17 places the ceramic grinding wheel on the lifting platform. The lifting platform has the characteristic of height adjustment, which reduces the height difference between the lifting platform and the pneumatic suction cup 17, reduces the impact force on the ceramic grinding wheel, reduces damage, and improves the yield of ceramic grinding wheels. Then the disc 15 is reversed 180 degrees to reset.

[0021] Example 2: A pressing and forming device for producing ceramic grinding wheels includes a frame 1, a mounting plate 2 rotatably mounted on the frame 1, the mounting plate 2 rotating on the frame 1, six support arms 3 evenly spaced on the mounting plate 2, the included angle between adjacent support arms 3 being 60 degrees, a drive mechanism mounted on the frame 1, the drive mechanism including a motor and a reducer, the reducer including an input shaft and an output shaft, the input shaft being connected to the motor, the output shaft being provided with a drive gear 4, a driven gear ring 5 coaxially mounted on a disc 15, the driven gear ring 5 meshing with the drive gear 4, a protective cover provided on the side of the disc 15 covering the driven gear ring 5 and the drive gear 4, the protective cover reducing the entry of ceramic grinding wheel raw material between the driven gear ring 5 and the drive gear 4.

[0022] Each end of the support arm 3 is equipped with a mold 6. The outer side of the frame 1 is evenly spaced with a fabric unit 7, a mesh placement unit 8, a trademark placement unit 9, a hole ring placement unit 10, a pressing unit 11, and a feeding unit. The drive mechanism drives the mounting plate 2 to rotate 60 degrees and then stops. After the fabric unit 7, mesh placement unit 8, trademark placement unit 9, hole ring placement unit 10, pressing unit 11, and feeding unit have all completed their work with the corresponding mold 6, they continue to rotate 60 degrees.

[0023] The six support arms 3 of the mounting plate 2 correspond to the fabric unit 7, the mesh placement unit 8, the trademark placement unit 9, the hole ring placement unit 10, the pressing unit 11, and the unloading unit, respectively. At the same time, they perform fabrication, mesh placement, trademark placement, hole ring placement, pressing, and unloading operations on the molds 6 on different support arms 3.

[0024] The unloading unit includes a lifting frame 12, which is positioned above the support arm 3 and does not interfere with the movement of the support arm 3. The lifting frame 12 is vertically rotatable and has a drive shaft 13. The lifting frame 12 is equipped with a reciprocating rotation mechanism 14 connected to the drive shaft 13. The reciprocating rotation mechanism 14 controls the drive shaft 13 to rotate 180 degrees forward and then 180 degrees backward to reset. A disc 15 is provided at the lower end of the drive shaft 13. Two vertical shafts 16 are evenly spaced at the lower end of the disc 15. A pneumatic suction cup 17 is provided at the lower end of each vertical shaft 16. The pneumatic suction cup 17 is existing technology and will not be described in detail here. The pneumatic suction cup 17 is connected to an external air supply mechanism and control mechanism through a pipe. The pneumatic suction cup 17 is used to hold the pressed ceramic grinding wheel inside the mold 6.

[0025] A lifting platform is provided at the lower end of the lifting frame 12. The lifting platform includes a base plate 18 and a top plate 19. Multiple vertically extending electric telescopic rods 20 are fixedly installed between the base plate 18 and the top plate 19. A limit rod 21 is vertically installed on the lifting frame 12 below the lifting platform. The lifting platform is provided with a through hole 22 for the limit rod 21 to pass through. The lifting platform corresponds vertically to the disc 15. After the pneumatic suction cup 17 picks up the resin grinding wheel, it rotates 180 degrees through the disc 15 to correspond vertically to the lifting platform. Then, the pneumatic suction cup 17 places the ceramic grinding wheel on the lifting platform. The lifting platform has the characteristic of height adjustment, which reduces the height difference between the lifting platform and the pneumatic suction cup 17, reduces the impact force on the ceramic grinding wheel, reduces damage, and improves the yield of ceramic grinding wheels. Then, the disc 15 is reversed 180 degrees to reset.

[0026] An encoder 23 is installed on the frame 1, and the encoder 23 is connected to the drive gear 4. A controller 24 is installed on the frame 1, and the controller 24 is connected to both the encoder 23 and the electric telescopic rod 20. The encoder 23 transmits information to the controller 24 through the rotation angle of the drive gear 4. The controller 24 controls each electric telescopic rod 20 to extend and retract synchronously, thereby adjusting the height of the lifting platform. When the lifting platform is lowered to the lowest point, the ceramic grinding wheel on the support platform is removed, and the controller 24 controls the lifting platform to rise to the top plate 19 close to the support arm 3.

[0027] The working principle is as follows:

[0028] After the drive mechanism drives the mounting plate 2 to rotate 60 degrees, it stops. After the material feeding unit 7, mesh placement unit 8, trademark placement unit 9, hole ring placement unit 10, pressing unit 11 and unloading unit have all completed their work with the corresponding mold 6, it continues to rotate 60 degrees. When unloading the pressed ceramic grinding wheel, the lifting platform rises to the height of the top plate 19 close to the support arm 3. The lifting frame 12 controls the pneumatic suction cup 17 to lower and suction the ceramic grinding wheel in the mold 6. When the pneumatic suction cup 17 places the suction cup on the lifting platform, the height difference is small, which reduces the risk of the grinding wheel being broken due to impact when it is pressed and not yet fired, and improves the yield of resin grinding wheels. The encoder 23 transmits information to the controller 24 through the rotation angle of the drive gear 4. The controller 24 controls each electric telescopic rod 20 to extend and retract synchronously, thereby adjusting the height of the lifting platform.
