Description

Technical Field

[0001] The utility model belongs to the technical field of powder metallurgy preparation, and particularly relates to an automatic compaction device. Background Art

[0002] In the preparation process of electrician alloy products, the billets are usually contained in boats made of square graphite materials, and then corundum powder is filled around the billets in the boats and put into a sintering furnace for sintering. Since the corundum powder has a small linear expansion coefficient at high temperatures (1400°C) and stable thermal properties, it plays a shaping role for the sintered products at high temperatures, and due to the high temperature resistance and high specific heat of the corundum powder, etc., it plays a good heat preservation role for the sintered products during the sintering process. However, during the sintering process of the billets, the compaction density and uniformity of the corundum powder determine the quality of the electrician alloy products sintered from the billets. Therefore, after filling the corundum powder, it is often necessary to tamp or compact the corundum powder to ensure that there are no loose or hollow phenomena inside the filled corundum powder.

[0003] At present, for the tamping or compaction of the corundum powder before sintering, it is usually manually tamped. That is, a tamping hammer is held by hand and evenly tamped from above the corundum powder to eliminate the voids inside the corundum powder and tamp the corundum powder. However, during the manual tamping process, since the air force of each manual tamping cannot be accurately controlled, the corundum powder in some areas of the boat is over-tamped or under-tamped. The over-tamped corundum powder area in the boat is too dense, which will increase the internal stress of the corundum powder. During the sintering process, the increased internal stress will cause cracks or fractures in the billets, increasing the production cost; if it is the area of the corundum powder in the boat that is under-tamped, there will be voids in this area, affecting the density and stability of the powder. Summary of the Utility Model

[0020] Compared with the prior art, the utility model has the following beneficial technical effects:

[0021] The utility model discloses an automatic compaction device. In this device, a graphite boat is placed on the compaction part, and the graphite boat is used to place green bodies and fill corundum powder. By starting the compaction part, the corundum powder is compacted and the graphite boat is limited. The filled corundum powder is vibrated by the vibration part, and then the void areas inside the corundum powder in the graphite boat are eliminated by mechanical vibration, improving the filling density and material uniformity, making the pressure received by the corundum powder in the graphite boat consistent during the ramming process, and thus ensuring that the ramming force and number of times received by the corundum powder in the graphite boat are consistent, ensuring uniform ramming of the corundum powder and improving production efficiency. At the same time, during the ramming process of this device, only the switch of the corresponding component needs to be operated to complete the ramming or vibration of the corundum powder, greatly improving production efficiency, reducing the need for manual operation, and lowering production costs.

[0022] Furthermore, in this device, the buffer member provides a dynamic buffering effect for the vibration platform through the sliding between the connecting sleeve and the connecting column, and then in cooperation with the compression or extension of the spring. This enables the vibration platform to remain stable during vibration, avoiding direct impact and extending the service life of the equipment. At the same time, the compression and extension of the spring can be adaptively adjusted according to the requirements of the vibration platform to adapt to different vibration amplitudes and frequencies, providing a dynamic buffering and stabilizing effect for the automatic compaction device for filling corundum powder in powder metallurgy, reducing noise and vibration transmission, and improving the reliability and flexibility of the equipment.

[0023] Even further, an adjusting member is provided between the vibration platform and the mounting base in this device. In the adjusting member, the distance between the vibration platform and the mounting base can be adjusted through the limit screw, so that this device can adjust the vibration amplitude of the vibration platform according to the requirements of different green body materials or processes, improving the adaptability and flexibility of the equipment, optimizing the compaction effect, and extending the service life of the equipment.

[0024] Even further, the pressing member in this device includes a telescopic cylinder. The telescopic cylinder is installed on the connecting member, and the telescopic cylinder is a pneumatic cylinder. A compaction plate is connected to the telescopic head of the pneumatic cylinder. By controlling the telescopic movement of the pneumatic cylinder, the compaction plate moves towards the bottom of the graphite boat, realizing the automation of compaction, reducing the need for manual operation, and improving production efficiency. At the same time, it also reduces the labor intensity of the operator and improves the working environment. In this pressing member, by controlling the speed and displacement of the pneumatic cylinder, the ramming force of the compaction plate on the corundum powder can be controlled, ensuring that the corundum powder in the graphite boat reaches the best density and uniformity, thereby improving the performance and reliability of the final product. And during the process of the compaction plate moving towards the bottom of the graphite boat, the corundum powder in the graphite boat is overall compacted and the graphite boat is limited, making the compacted corundum powder compacted uniformly.

[0025] Furthermore, a support member is provided at the bottom of the mounting base in this device. By adjusting the height of the adjustable telescopic rod, the height of the vibrating platform in this device is adjusted, thereby adapting to different working environments or production line configurations, and improving the adaptability and flexibility of the equipment.

[0035] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0036] See Figures 1 to 3 , the present utility model discloses an automatic compaction device, which includes an installation base 3. A compaction part 1 is installed above the installation base 3. A pressing part 2 is installed on the compaction part 1 and a graphite boat 11 is placed thereon. The pressing part 2 is located above the graphite boat 11. When a green body is loaded into the graphite boat 11 and then filled with corundum powder, an operator controls the pressing part 2 to move downward, so that the lower end of the pressing part 2 extends into the graphite boat 11 to compact the corundum powder and limit the graphite boat 11 to prevent it from moving. Then, the compaction part 1 is controlled to work to compact the corundum powder. This device replaces the current manual ramming and compaction work with machine work, realizes the consistency and stability of the boat loading quality, avoids the phenomenon of uneven manual force during manual ramming, which may cause looseness or voids inside the corundum powder, and improves labor efficiency and reduces labor intensity at the same time.

[0037] See Figures 1 to 3 , the compaction part 1 includes a vibration platform 8. The graphite boat 11 is placed on the upper end surface of the vibration platform 8. A vibrating member is installed on the bottom end surface of the vibration platform 8. The vibrating member is a vibration motor 7. By the action of the vibration motor 7 on the vibration platform 8, the vibration platform 8 vibrates, thereby eliminating the void areas inside the corundum powder in the graphite boat 11 on the vibration platform 8.

[0038] SeeFigures 1 to 3 , a buffer member is connected to the bottom end face of the vibrating platform 8, and the buffer member is installed on the upper end face of the mounting base 3. The buffer member includes a connecting sleeve. The bottom end face of the connecting sleeve is vertically and fixedly installed on the mounting base 3. A connecting column is movably installed in the connecting sleeve. The upper end of the connecting column extends out from the upper end port of the connecting sleeve and is connected to the bottom end face of the vibrating platform 8. A spring 4 is sleeved on the connecting column between the vibrating platform 8 and the mounting base 3. When the compaction part 2 and the vibrating compaction part 1 act on the vibrating platform 8, the vibration received by the mounting base 3 is weakened through the expansion and contraction of the spring 4.

[0039] See Figures 1 to 3 , an adjusting member is provided between the vibrating platform 8 and the mounting base 3. The adjusting member includes a limit screw 5. A threaded hole is provided on the vibrating platform 8. One end of the limit screw 5 is screwed into the threaded hole. An installation hole is provided on the mounting base 3, and the limit screw 5 is slidably inserted through the installation hole, so that the limit screw 5 is movably installed on the mounting base 3. By adjusting the limit screw 5, the depth of its screwing into the threaded hole is adjusted to adjust the distance between the vibrating platform 8 and the mounting base 3. An adjusting nut 6 is screwed at the position where the limit screw 5 abuts against the upper end face of the mounting base 3 to limit the vertical movement height of the vibrating platform 8 during the compaction of corundum powder.

[0040] See Figures 1 to 3, the compaction part 2 includes a connecting piece which connects the vibration platform 8. A pressing piece 10 is installed on the same-side end face of the connecting piece. The connecting piece is a gantry 9 which is installed on the vibration platform 8 and spans across the vibration platform 8, such that the graphite boat 11 is located on one side of the gantry 9. A plurality of fixing platforms are arranged side by side on the front end face of the gantry 9, and a pressing piece 10 is vertically installed on each fixing platform. The pressing piece 10 includes a telescopic cylinder which is installed on the fixing platform, and the telescopic head of the telescopic cylinder is vertically downward. When compacting the corundum powder filled in the graphite boat 11, by moving the position of the graphite boat 11 on the vibration platform 8, the telescopic head of the telescopic cylinder is vertically aligned with the opening of the graphite boat 11. A compaction plate is connected to the telescopic head of the telescopic cylinder, and the compaction plate is aligned and parallel to the opening of the graphite boat 11. During the process of compacting the corundum powder filled in the graphite boat 11, through the telescopic movement of the telescopic cylinder, the compaction plate vertically moves towards the bottom end face of the graphite boat 11, and then the compaction plate enters the graphite boat 11 from the upper opening of the graphite boat 11 and compacts downward as a whole from the upper part of the corundum powder, making the corundum powder evenly compacted. At the same time, the size of the compaction plate is the same as the inner cavity size of the graphite boat 11. Thus, when the compaction plate enters the graphite boat 11, there is a very small gap between the compaction plate and the inner wall of the graphite boat 11, which can more fully compact the corundum powder filled in the graphite boat 11 as a whole, and at the same time limit the graphite boat 11 and fix its position on the vibration platform 8 to prevent it from moving on the vibration platform 8 during the operation of the vibration part 1 and affecting the vibration compaction of the corundum powder. In this embodiment, the telescopic cylinder is a pneumatic cylinder, and a gas source is connected to the pneumatic cylinder.

[0041] See Figures 1 to 3 , a support piece is provided at the bottom of the installation base 3. The support piece includes a connecting platform which is installed at the position of the bottom end face of the vibration platform 8 at its corner. The upper end head of a hydraulic telescopic oil cylinder is connected to the bottom end face of the connecting platform. The hydraulic telescopic oil cylinder is vertically installed, and a hydraulic oil tank and a hydraulic oil transfer pump are connected to the hydraulic telescopic oil cylinder. The lower end head of the hydraulic telescopic oil cylinder is connected to an installation platform, and feet are installed on the bottom end face of the installation platform. The installation base 3 is lifted from the ground by the support piece and the feet. And during the installation process of this device, by adjusting the height of the hydraulic telescopic oil cylinder in the adjusting part, the height of the vibration platform 8 is adjusted, so that this device can be applicable to different process production lines.
