Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding wheel production, in particular to a diamond grinding wheel grinding tool. Background Art

[0002] Diamond grinding wheel is a kind of grinding wheel tool that uses diamond as abrasive. It is made of natural or artificial diamond powder as the main raw material, and is sintered with different resin binders or powder metallurgy technology. Diamond grinding wheels have the characteristics of high hardness, high wear resistance, high precision and stability, so they are widely used in processing various non-ferrous materials such as glass, silicon, ceramics, sapphire, and superhard materials such as PCD. Diamond grinding wheel tools usually consist of three parts: diamond abrasive layer, transition layer and matrix. Among them, the diamond layer is the working part of the grinding wheel, which is composed of abrasives, binders and fillers; the transition layer is used to firmly connect the diamond layer to the matrix. The grinding wheel embryo is usually formed by pressing a molding material composed of abrasives, binders and other raw materials through a grinding wheel mold.

[0003] For example, the Chinese authorized patent "A Diamond Grinding Wheel Abrasive Tool" with announcement number CN220052947U includes a base plate and a support frame fixed on the top of the base plate, the top of the support frame is fixedly connected with a hydraulic push rod, the output end of the hydraulic push rod passes through the top wall of the support frame and is fixedly connected with a lifting plate, the bottom of the lifting plate is provided with a first connecting plate, the bottom of the first connecting plate is provided with an upper mold, the bottom of the upper mold is provided with a lower mold, and the top of the base plate is provided with a placement groove. First, the second connecting plate is driven to move upward by starting the motor, and the top plate of the material discharge can be driven to move upward inside the mold groove by the connecting rod, thereby pushing the grinding wheel embryo body after pressing inside the mold groove upward until the grinding wheel embryo body is pushed out from the inside of the mold groove.

[0004] Although the above-mentioned prior art can realize the ejection of the processed grinding wheel, the ejection structure is relatively complicated, which affects the convenience of material removal. In addition, when injecting material into the lower mold, gaps are easily present between the powder materials, and the powder materials are unevenly distributed, which affects the overall quality of the grinding wheel after pressing. Therefore, it does not meet the existing needs. In this regard, we propose a diamond grinding wheel abrasive tool. Utility Model Content

[0005] The utility model aims to provide a diamond grinding wheel tool to solve the problems of the device's complicated and inconvenient ejection structure and the existence of gaps and uneven distribution between powders during the injection process proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a diamond grinding wheel grinding tool, comprising a workbench, a support plate is welded and fixed to the rear side of the upper end surface of the workbench, a top plate is welded and fixed to the front side of the top of the support plate, and a hydraulic lifting device is fixedly installed at the lower end of the top plate; and further comprising:

[0007] A fixing seat, which is arranged at the movable end of the hydraulic lifting device, and the fixing seat and the hydraulic lifting device are fixed by bolts, an upper mold is installed at the lower end of the fixing seat, and a receiving groove is arranged on one side inside the fixing seat;

[0008] The lower mold is arranged in the middle position of the workbench, and a support seat is installed at the bottom of the inner cavity of the lower mold. A connecting arm is integrally formed on one side of the support seat by casting, and one side of the inner cavity of the lower mold provides a groove for placing the connecting arm. The edges of the connecting arm and the support seat are respectively fitted with the lower mold and the provided groove, and the connecting arm and the support seat are respectively slidably connected to the lower mold and the provided groove, and the upper end of the connecting arm extends to the inside of the storage groove, and the upper end of the connecting arm is limited by the sliding of the storage groove.

[0009] Preferably, the workbench is located at the outer ring of the lower mold and is provided with an annular groove, an annular tooth groove connected to the annular groove is provided below the annular groove, and the racks are distributed on the outside of the inner cavity of the annular tooth groove, and an injection mechanism is provided above the annular groove, and the injection mechanism includes an adjusting block, a sliding seat is installed at the bottom of the adjusting block, and the sliding seat is slidably matched with the annular groove, rollers are rotatably installed on both sides of the sliding seat, and the rollers are fitted with the annular groove, and a first motor is fixedly installed inside the sliding seat, and a gear is installed on the output shaft of the first motor, and the gear is meshed with the annular tooth groove.

[0010] Preferably, an injection pipe is installed inside the adjusting block, and the injection pipe is connected to the adjusting block through a rotating shaft, a feeding pipe extending to the outside of the adjusting block is installed at the rear end of the injection pipe, a second motor is fixedly installed on the upper end of the adjusting block, and the output shaft of the second motor is connected to the rotating shaft between the injection pipe and the adjusting block.

[0011] Preferably, a vibration motor is installed at the bottom of the lower mold, and four vibration motors are provided and distributed in a ring shape.

[0012] Preferably, a core rod is fixedly provided at a middle position of the upper end surface of the support seat, and a groove for the core rod to pass through is reserved at the center position of the upper mold.

[0013] Preferably, a return spring is fixedly installed between the receiving groove and the upper end of the connecting arm.

[0014] Preferably, the injection tube is rotatably switched between zero degrees and ninety degrees.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model arranges the ejection mechanism of the grinding wheel on the fixed seat where the upper mold is located. Before the powder is injected, the support seat is located at the bottom of the lower mold, and the subsequently injected powder can fall on the top of the support seat. After the injection is completed, the hydraulic lifting device is turned on to drive the upper mold to move downward through the fixed seat until it enters the lower mold to extrude the powder, thereby realizing the molding of the diamond grinding wheel. During the downward pressing process, the upper end of the connecting arm gradually shrinks into the receiving groove of the fixed seat, which will not affect the entire pressing work. After pressing, with the lifting of the hydraulic lifting device, the connecting arm is also moved out of the placement cavity under the action of gravity, and finally, under the traction of the fixed seat, the supporting seat is driven to rise by the connecting arm to realize separation from the lower mold. At this time, the molded grinding wheel is located above the workbench, and the staff can easily take it out. The discharging mechanism is not only simple in structure, but also can realize the ejection work in the process of lifting and moving in cooperation with the upper mold, and the convenience is further improved.

[0017] 2. The utility model is provided with an injection mechanism. During the injection process, the powder is transported through the feeding pipe and enters the lower mold through the injection pipe. During the injection process, the first motor is turned on, and its output shaft drives the gear to rotate. Since the sliding seat on the injection mechanism is movably limited on the annular groove, the gear is engaged with the annular tooth groove on the workbench. Then, the rotation of the gear can drive the injection mechanism to make an annular motion on the annular groove, thereby evenly injecting the powder into the interior of the lower mold, effectively improving the uniformity of injection and improving the pressing quality of the diamond grinding wheel.

[0018] 3. The utility model installs a vibration motor at the bottom of the lower mold. When the vibration motor is started, the eccentric block inside it will rotate at a high speed. The eccentric block will generate centrifugal force when rotating. This centrifugal force is transmitted to the bottom of the mold through the shaft of the motor, and then converted into an exciting force. This exciting force acts on the injected powder to vibrate the powder particles. Due to the effect of vibration, the powder particles begin to move relative to each other, and the original gaps begin to be filled by the surrounding powder particles. At the same time, the vibration also promotes the friction and rearrangement between the powder particles, making the contact between the particles closer and further reducing the gaps. The vibration motor not only provides the power required to remove the gaps, but also ensures the uniformity and compactness of the powder distribution through its continuous and stable vibration. This helps to improve the quality of the product and reduce performance problems caused by the existence of gaps. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting arm 9 is integrally formed on one side of the support seat 21 by casting, and one side of the inner cavity of the lower mold 8 provides a groove for placing the connecting arm 9. The edges of the connecting arm 9 and the support seat 21 are respectively fitted with the lower mold 8 and the provided groove, and the connecting arm 9 and the support seat 21 are respectively slidably connected with the lower mold 8 and the provided groove, and the upper end of the connecting arm 9 extends to the inside of the storage groove 23, and the upper end of the connecting arm 9 is slidably limited with the storage groove 23.

[0029] When in use, before the powder is injected, the support seat 21 is located at the bottom of the lower mold 8, and the subsequently injected powder can fall above the support seat 21. After the injection is completed, the hydraulic lifting device 4 is turned on, and the upper mold 6 is driven to move downward through the fixed seat 5 until it enters the lower mold 8 to extrude the powder, thereby realizing the molding of the diamond grinding wheel. During the downward pressing process, the upper end of the connecting arm 9 gradually shrinks into the receiving groove 23 of the fixed seat 5, which will not affect the entire pressing work. After pressing, with the lifting of the hydraulic lifting device 4, the connecting arm 9 is also moved out of the receiving groove 23 under the action of gravity, and finally, under the traction of the fixed seat 5, the connecting arm 9 is used to drive the support seat 21 to rise to achieve separation from the lower mold 8. At this time, the formed grinding wheel is located above the workbench 1, and the staff can easily take it out.

[0032] See also Figure 1 and Figure 5A vibration motor 10 is installed at the bottom of the lower mold 8. There are four vibration motors 10, and the vibration motors 10 are distributed in a ring shape. When the vibration motor 10 is started, the eccentric block inside it will rotate at a high speed. The eccentric block will generate centrifugal force when rotating. This centrifugal force is transmitted to the bottom of the mold through the shaft of the motor, and then converted into an exciting force. This exciting force acts on the injected powder, causing the powder particles to vibrate. Due to the effect of vibration, the powder particles begin to move relative to each other, and the original gaps begin to be filled by the surrounding powder particles. At the same time, the vibration also promotes the friction and rearrangement between the powder particles, making the contact between the particles closer and further reducing the gaps.
