Description

Technical Field

[0001] This utility model relates to the field of packing device technology, specifically a packing device for preparing cubic boron nitride cutting tools. Background Technology

[0002] In the field of modern machining, cubic boron nitride (CBN) cutting tools have become ideal tool materials for machining high-hardness materials such as hardened steel and chilled cast iron due to their excellent properties such as high hardness, high wear resistance, good thermal stability and chemical stability. As the manufacturing industry continues to increase its requirements for machining accuracy and efficiency, the demand for CBN cutting tools is also growing.

[0003] The raw materials for making cubic boron nitride (CBN) cutting tools are pulverized into powder, mixed evenly, and then quantitatively filled into a mold for drying and sintering. However, the hardness of the CBN raw materials themselves may be uneven after pulverization and mixing, with the presence of crystal nuclei or impurities with higher hardness. During the pulverization process, the parts with lower hardness are easily pulverized into powder, while the parts with higher hardness may remain as particles. When filling the mold, the particles cannot be effectively filtered, which affects the subsequent manufacturing of the cutting tools and reduces their performance. Therefore, further optimization is needed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a filling device for preparing cubic boron nitride cutting tools, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a filling device for preparing cubic boron nitride cutting tools, comprising a base plate, a support plate, a mold, and a filling cylinder;

[0006] The packing cylinder is fixedly connected to the top of the base plate by a support plate. The upper conveying roller and the lower conveying roller are rotatably connected inside the packing cylinder, and a filter layer for filtering particulate raw materials is provided in the middle part. The left end of the packing cylinder is provided with a storage box for storing particulate raw materials, and the right end is provided with a drive component for driving the upper conveying roller and the lower conveying roller to rotate.

[0007] The bottom of the left end of the packing cylinder is provided with a discharge hose, and the top of the right end is provided with a feed port. The mold is located on the upper surface of the base plate. The feed port of the mold is connected to the bottom end of the discharge hose. The right end of the lower conveying roller is provided with a power component that drives the mold to move left and right.

[0008] This utility model has the following beneficial effects:

[0009] This is a filling device for preparing cubic boron nitride cutting tools. The crushed raw material enters the upper space of the filling cylinder through the feed inlet. With the help of the filter layer, larger impurities in the raw material can be filtered and fall into the lower space. The upper and lower conveying rollers are rotated by the drive component. The upper conveying roller can transport the larger impurities to the inside of the storage box, and the lower conveying roller can transport the filtered material to the inside of the mold through the discharge hose. This facilitates the filtration of larger particles during filling, improves the performance of the cubic boron nitride cutting tools produced by subsequent sintering, and makes the quality of the produced tools more stable and reliable.

[0010] This is a filling device for preparing cubic boron nitride cutting tools. When the motor is started, the drive wheel can be driven to rotate. Since the surface of the drive wheel has a toothed area and a toothless area, when the toothed area of ​​the drive wheel meshes with the driven wheel, it synchronously drives the gear to rotate. When it rotates to the toothless area, the driven wheel and the gear stop rotating, which facilitates the intermittent delivery of raw materials to the inside of the mold and reduces the accumulation of raw materials inside the mold.

[0011] This filling device for preparing cubic boron nitride cutting tools can weigh the raw materials entering the mold through a weighing sensor installed in the base plate, maintaining a quantitative output of materials. When the gear rotates, it synchronously drives the rack, vertical rod and eccentric wheel to rotate. With the cooperation of the horizontal rod and the limiting frame, it can synchronously drive the mold to sway left and right, reducing the agglomeration of raw materials inside the mold and making the raw materials evenly dispersed in the mold.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figures 1 to 4 This utility model provides a filling device for preparing cubic boron nitride cutting tools; including a base plate 1, a support plate 2, a mold 3 and a filling cylinder 4;

[0019] The packing cylinder 4 is fixedly connected to the top of the base plate 1 by the support plate 2, which can support the packing cylinder 4 and maintain the stability of the packing cylinder 4. The packing cylinder 4 is rotatably connected to the upper conveying roller 5 and the lower conveying roller 6, and a filter layer 7 for filtering particulate raw materials is provided in the middle part. The left end of the packing cylinder 4 is provided with a storage box 8 for storing particulate raw materials, which allows larger particulate raw materials conveyed by the upper conveying roller 5 to enter its interior for centralized processing later. The right end is provided with a drive component for driving the upper conveying roller 5 and the lower conveying roller 6 to rotate.

[0020] like Figure 1-2 As shown, the filter layer 7 divides the interior of the packing cylinder 4 into an upper cavity and a lower cavity, so that the upper conveying roller 5 is located inside the upper cavity and the lower conveying roller 6 is located inside the lower cavity. When the upper conveying roller 5 rotates, it can further stir the particles in the raw material, and at the same time, it is convenient to store the larger particles in the filtered raw material into the storage box 8 for later centralized processing.

[0021] The bottom of the left end of the packing cylinder 4 is provided with a discharge hose 9, and the top of the right end is provided with a feed port. The mold 3 is located on the upper surface of the base plate 1. The feed port of the mold 3 is connected to the bottom end of the discharge hose 9. The right end of the lower conveying roller 6 is provided with a power component that drives the mold 3 to move left and right.

[0022] When the conveyor roller 6 rotates, it can drive the filtered raw material to be intermittently transported through the discharge hose 9 to the inside of the mold 3, reducing the accumulation of raw material inside the mold 3.

[0023] The driving component includes a motor 10 fixedly connected to the right end of the packing cylinder 4. The output end of the motor 10 extends into the interior of the packing cylinder 4 and is fixedly connected to a drive wheel 11. The left end of the drive wheel 11 is fixedly connected to the right end of the upper conveying roller 5. The right end of the packing cylinder 4 is provided with a driven wheel 12 meshing with the drive wheel 11 and a gear 13 meshing with the driven wheel 12. The left side of the gear 13 is fixedly connected to the right end of the lower conveying roller 6.

[0024] like Figure 2-3As shown, starting the motor 10 can drive the drive wheel 11 and the upper conveying roller 5 to rotate. Since the surface of the drive wheel 11 has a toothed area and a toothless area (shown in the figure), when the part of the drive wheel 11 with the toothed area meshes with the driven wheel 12, it synchronously drives the gear 13 and the lower conveying roller 6 to rotate. When it rotates to the toothless area, the driven wheel 12 and the lower conveying roller 6 stop rotating, so that the raw material is intermittently conveyed to the inside of the mold 3, reducing the accumulation of raw material inside the mold 3.

[0025] The power assembly includes a support column 14 fixedly connected to the right end of the filling cylinder 4. The bottom end of the support column 14 is fixedly connected to the upper surface of the base plate 1. The right end of the gear 13 is fixedly connected to a rack 15. The right end of the rack 15 extends into the interior of the support column 14 and is meshed with a vertical rod 16. The bottom end of the vertical rod 16 extends into the interior of the base plate 1 and is fixedly connected to an eccentric wheel 17. A crossbar 18 is provided on the lower surface of the eccentric wheel 17. A limiting frame 19 is provided on the upper surface of the base plate 1 and around the mold 3. The left end of the crossbar 18 passes through a slide rail opened on the upper surface of the base plate 1 and is fixedly connected to the limiting frame 19. A weighing sensor is provided inside the base plate 1 and below the mold 3, which can conveniently weigh the raw materials inside the mold 3 and maintain quantitative filling.

[0026] The right end of the rack 15 and the top of the vertical rod 16 are provided with helical gears, which mesh with each other. When the gear 13 rotates, the eccentric wheel 17 is driven to rotate synchronously under the cooperation of the rack 15 and the vertical rod 16. Since the right end of the horizontal rod 18 is movably connected to the lower surface of the eccentric wheel 17, the horizontal rod 18 reciprocates when the eccentric wheel 17 rotates. Since the left end of the horizontal rod 18 is fixedly connected to the limiting frame 19, and the mold 3 is located inside the limiting frame 19, the limiting frame 19 drives the mold 3 to also reciprocate left and right, which facilitates the improvement of the uniformity of the raw materials inside the mold 3.

[0027] When the mold 3 moves left and right, the discharge hose 9 can move in coordination with it to maintain the sealing of the material discharge. At the same time, depending on the use, a telescopic hose can be used. The bottom end of the discharge hose 9 is connected to the feed port of the mold 3 in a snap-fit ​​manner, which makes it easy to disassemble after filling is completed.

[0028] Suction cups 20 are fixedly connected to the four corners of the bottom of the base plate 1, which can maintain the stability of the equipment when it is placed on the ground. The right side of the limiting frame 19 is provided with a positioning ring for limiting the mold 3. Rotating the positioning ring can make one end of it press against the mold 3, which is convenient for limiting it.

[0029] The motor 10 and the weighing sensor mentioned above are all existing technologies, and are only cited here. Their specific structures will not be described in detail.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0031] In this invention, the working steps of the device are as follows:

[0032] In use, the crushed raw material is placed into the filling cylinder 4 through the feed inlet, the mold is placed in the middle of the limiting frame 19, and the positioning ring is rotated to fix it. Then, the motor 10 is started to drive the upper conveying roller 5 to rotate. The filter layer 7 is used to filter the larger particles in the raw material. The larger particles are transported to the storage box 8 for collection through the upper conveying roller 5. The filtered raw material is then transported intermittently by the lower conveying roller 6 with the cooperation of the driven wheel 12 and the gear 13, so that the raw material is transported to the inside of the mold 3 through the discharge hose 9. With the cooperation of the power component, the uniformity of the raw material inside the mold 3 can be further maintained.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
