Description

Technical Field

[0001] This utility model relates to the field of grinding wheel forming technology, specifically to a grinding wheel forming device. Background Technology

[0002] A grinding wheel forming device is a specialized piece of equipment used to manufacture grinding wheels. Its main working principle is to apply pressure to compress the raw material of the grinding wheel into a grinding wheel of a specific shape and size.

[0003] During the grinding wheel forming process, if the grinding wheel contains a lot of sticky components, such as certain resin binders, the resin may adhere to the mold surface during cooling after pressing, making it difficult to remove the formed grinding wheel. Furthermore, for grinding wheels with higher density and hardness, the formed grinding wheel adheres even more closely to the mold after forming and extrusion, which also makes it difficult to remove the formed grinding wheel. The operator needs to manually hammer the formed grinding wheel to separate it from the mold, which is a cumbersome operation and affects the efficiency of grinding wheel forming.

[0004] Therefore, there is an urgent need for a grinding wheel forming device to solve the above problems. Utility Model Content

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

[0023] Please see Figure 1-4 The present invention provides a grinding wheel forming device, including an operating table 101 and a forming frame 102 fixed to the upper end of the operating table 101. A mounting frame 103 is fixed on the forming frame 102. A lower mold 104 and an upper mold 105 for assisting grinding wheel forming are arranged between the forming frame 102 and the mounting frame 103. The device also includes:

[0024] A lifting assembly for raising and lowering the upper mold 105 and a feeding assembly for feeding material during the grinding wheel forming process are provided on the mounting frame 103;

[0025] The mounting assembly for mounting the lower mold 104 and the moving assembly for moving the lower mold 104 are provided on the forming frame 102. The forming frame 102 is also provided with a vibration assembly for impacting and vibrating the lower mold 104 during the movement.

[0026] It should be noted that during the grinding wheel forming process, the grinding wheel forming device, through transmission, can both facilitate the more uniform distribution of the forming material inside the lower mold 104 by striking and vibrating the lower mold 104 after the material is fed onto the lower mold 104 and then moved, thus ensuring the quality of the forming process, and also facilitate the separation of the formed grinding wheel from the lower mold 104 by striking and vibrating the lower mold 104 after the grinding wheel is formed and when it is moved to the designated position, eliminating the need for manual knocking and separation and ensuring the efficiency of the grinding wheel forming process.

[0027] The mounting components include a movable plate 401 mounted on the folding frame 102, a base 402 fixed to the lower end of the lower mold 104, the movable plate 401 being located below the base 402, and the movable plate 401 being connected and fixed to the base 402 by multiple sets of fixing rods 403.

[0028] It should be noted here that the movable plate 401, the base 402 and the fixing rod 403 facilitate the installation and connection of the lower mold 104.

[0029] The vibration assembly includes a fixed frame 601 fixed to the lower end of the base 402, a mounting shaft 602 rotatably connected to the fixed frame 601, two sets of drive discs 603 symmetrically fixed to the mounting shaft 602, and multiple sets of rubber protrusions 604 for striking against the lower end of the base 402 fixed in a circular array on the outer side of the drive discs 603. A rotating assembly for rotating the mounting shaft 602 is provided between the ring frame 102 and the mounting shaft 602. The rotating assembly includes a gear 701 fixed to the mounting shaft 602, a rack 702 fixed to the ring frame 102, and the gear 701 and the rack 702 are meshed with each other.

[0030] It should be noted that during the movement of the base 402 and the lower mold 104, the mounting shaft 602 and the gear 701 on the mounting shaft 602 are driven to move through the connection of the fixing frame 601. During the movement of the gear 701, the mounting shaft 602 is rotated through the meshing transmission between the gear 701 and the rack 702. During the rotation of the mounting shaft 602, the rubber protrusions 604 on the drive disc 603 are driven to abut against the lower end of the base 402 in sequence. During the abutment process, the base 402 and the lower mold 104 are vibrated due to the impact.

[0031] The moving component includes a threaded sleeve 501 fixed on the moving plate 401, a threaded rod 502 rotatably connected to the rotating frame 102, the threaded rod 502 and the threaded sleeve 501 being meshed with each other, a drive motor 503 for driving the threaded rod 502 is installed on the outside of the rotating frame 102, and a guide rod 504 is slidably connected to the moving plate 401, the guide rod 504 being fixed to the rotating frame 102;

[0032] It should be noted that: the drive motor 503 drives the threaded rod 502 to rotate. During the rotation of the threaded rod 502, the moving plate 401 is subjected to force and moves through the meshing transmission between the threaded rod 502 and the threaded sleeve 501. During the movement of the moving plate 401, the sliding guidance of multiple sets of guide rods 504 causes the moving plate 401 to move. During the movement of the moving plate 401, the lower mold 104 is driven to move synchronously through the connection between the base 402 and the fixed rod 403.

[0033] The lifting assembly includes a first fixed seat 201 fixed on the mounting bracket 103, and a cylinder 202 for lifting and driving the upper mold 105 is mounted on the first fixed seat 201.

[0034] It should be noted here that the cylinder 202 on the first fixed seat 201 facilitates the lifting and lowering of the upper mold 105.

[0035] The feeding assembly includes a second fixed base 301 fixed on the mounting frame 103. A storage cylinder 302 is fixed at the upper end of the second fixed base 301, and a feeding pipe 303 is fixed at the lower end of the storage cylinder 302. A control valve 304 for discharging control is installed on the feeding pipe 303.

[0036] It should be noted here that: by moving the lower mold 104, the lower mold 104 is positioned below the feeding assembly. After the movement is completed, the control valve 304 is opened, so that the molding material stored inside the storage cylinder 302 is transported to the interior of the lower mold 104 through the feeding pipe 303, thus completing the feeding operation of the lower mold 104.

[0037] Working principle: During the forming process of the grinding wheel by the grinding wheel forming device, the base 402 and the lower mold 104 move on the return frame 102 through the driving action of the moving component and the connecting action of the mounting component.

[0038] By moving the lower die 104, the lower die 104 is positioned below the feeding assembly. After the movement is completed, the control valve 304 is opened, allowing the molding material stored inside the storage cylinder 302 to be transported to the interior of the lower die 104 through the feeding pipe 303, thus completing the feeding operation of the lower die 104. After the feeding is completed, the control valve 304 is closed, and the lower die 104 is driven to move again. By moving the lower die 104, the lower die 104 is positioned below the upper die 105. After the movement is completed, the upper die 105 is driven by the cylinder 202 to move downwards towards the lower die 104. During the movement, pressure is applied to the molding material inside the lower die 104, pressing the raw material of the grinding wheel into a grinding wheel of a specific shape and size, thus completing the forming process of the grinding wheel.

[0039] After the grinding wheel forming process is completed, the lower die 104 is moved to the designated position on the return frame 102 by the moving component and unloaded. During the movement of the base 402 and the lower die 104, the fixed frame 601 connects and drives the mounting shaft 602 and the gear 701 on the mounting shaft 602 to move. During the movement of the gear 701, the meshing transmission between the gear 701 and the rack 702 causes the mounting shaft 602 to rotate. During the rotation of the mounting shaft 602, the rubber protrusions 604 on the drive disc 603 sequentially engage with the lower die of the base 402. When the ends collide, the base 402 and the lower mold 104 vibrate due to the impact. After the material is fed onto the lower mold 104 and during its movement, the vibration of the lower mold 104 facilitates a more uniform distribution of the molding material inside the lower mold 104, ensuring the quality of the molding process. After the grinding wheel is formed and the lower mold 104 is moved to the designated position, the vibration of the lower mold 104 facilitates the separation of the formed grinding wheel from the lower mold 104, eliminating the need for manual separation and ensuring the efficiency of the grinding wheel forming process.
