Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary shuttle inner shuttle production technology, specifically to a support plate that effectively improves the catalytic deesterification efficiency of rotary shuttle inner shuttle blanks. Background Technology
[0002] In powder metallurgy, forming lubricants are added to metal powders to improve their flowability, density during pressing, and demolding efficiency. These lubricants are mostly organic esters (such as stearates and palmitic acids), and their functions include: reducing friction between powder particles, ensuring uniform filling of the mold cavity; reducing adhesion between the billet and the mold wall, preventing breakage during demolding; and increasing the strength (temporary bonding force) of the green billet, facilitating subsequent transport. These ester lubricants can remain on the surface and in the internal pores of the billet. If these esters remain in the billet and enter the sintering process, they can significantly negatively impact sintering quality. Since sintering requires high temperatures (usually above 1000℃), the esters can decompose or burn at these temperatures, producing gases such as CO2 and H2O. If the gas cannot be discharged from the inside of the billet in time, it will form pores and looseness in the metal matrix, and may even cause the billet to expand and crack, which will seriously affect the density and mechanical properties after sintering. The residues after the combustion of esters may adhere to the inner wall of the sintering furnace. Long-term accumulation will pollute the furnace environment and affect the sintering quality of other billets. At the same time, the residual esters or their decomposition products may form carbide impurities on the surface of the billet, resulting in surface defects during subsequent processing (such as fine grinding and polishing).
[0003] Therefore, during the production process of rotary shuttle inner shuttle blanks, surface impurities and ester substances need to be removed with a cleaning solution to ensure the quality of subsequent sintering. Traditional support plates have a flat surface; when the rotary shuttle inner shuttle blank is placed on it, the contact surface between the blank and the support plate is almost flush, with virtually no gaps. This makes it difficult for the cleaning solution to penetrate this contact surface, creating cleaning dead zones and affecting the cleaning effect, which in turn negatively impacts the quality of subsequent sintering. Furthermore, traditional support plates lack a separating structure, allowing the blanks to be placed haphazardly and easily collide with each other, causing damage and further affecting production quality.
[0004] To address this, a support plate is proposed to effectively improve the catalytic deesterification efficiency of the inner shuttle blank. Utility Model Content

[0030] Example
[0031] The support plate provided in this embodiment effectively improves the catalytic deesterification efficiency of the inner shuttle blank, such as... Figures 1-2 As shown, it includes: a support substrate 1, on which a plurality of guide grooves 101 are provided for improving the catalytic deesterification efficiency of the inner shuttle blank of the rotary shuttle. Each group of guide grooves 101 has at least two, and a partition groove 102 is provided between adjacent groups of guide grooves 101.
[0032] During the production process, impurities and esters on the surface of the rotary shuttle blank need to be removed using a cleaning solution to ensure the subsequent sintering quality. Traditionally, the surface of the support plate is a flat surface. When the rotary shuttle blank 2 is placed on the support plate, the contact surface between the rotary shuttle blank 2 and the support plate is almost in a close fit, with almost no gaps between them. This makes it difficult for the cleaning solution to enter the contact surface between the rotary shuttle blank 2 and the support plate, resulting in cleaning dead corners and affecting the cleaning effect, which in turn affects the subsequent sintering quality. By setting up the guide channel 101, the cleaning solution can easily enter the contact surface between the rotary shuttle blank 2 and the support plate, eliminating cleaning dead corners and ensuring the cleaning effect to guarantee the subsequent sintering quality. At the same time, the partition channel 102 can help the workers to place the rotary shuttle blank 2 to be cleaned in an orderly manner on the upper part of the guide channel 101, avoiding the rotary shuttle blank 2 being placed randomly, which could cause collisions and damage.
[0033] Specifically, in this embodiment, the cross-sectional shape of the guide channel 101 is one of V-shape, U-shape, or trapezoid. The guide channel 101 adopts a V-shape, U-shape, or trapezoidal cross-sectional shape, which is conducive to the flow of cleaning fluid in the guide channel 101, and can better guide the cleaning fluid into the contact surface between the inner shuttle blank and the support substrate 1, thereby improving the flowability of the cleaning fluid and enhancing the cleaning effect.
[0034] Specifically, in this embodiment, the depth of the guide channel 101 ranges from 5mm to 20mm. The guide channel 101 has a certain depth, which ensures that there is enough space to accommodate the cleaning fluid, making it easier for the cleaning fluid to come into contact with the contact surface of the inner shuttle blank and the supporting substrate 1, thereby further improving the cleaning effect of the cleaning fluid on the contact surface.
[0035] Specifically, in this embodiment, the width of the dividing groove 102 ranges from 2mm to 8mm. The dividing groove 102 has a certain width, which can more effectively separate the areas of different groups of guide grooves 101, further regulate the placement of the inner shuttle blanks of the rotary shuttle, and more reliably avoid collision damage between the inner shuttle blanks of the rotary shuttle.
[0036] Specifically, in this embodiment, the carrier substrate 1 is made of a corrosion-resistant material, which is one of ceramics, aluminum alloys, or engineering plastics. The use of corrosion-resistant materials such as ceramics, aluminum alloys, or engineering plastics to the carrier substrate 1 resists the corrosion of the cleaning solution, extends the service life of the carrier substrate 1, and ensures that the carrier substrate 1 can stably perform its functions of supporting and assisting in cleaning over a long period.
[0037] Specifically, in this embodiment, a hydrophilic coating is provided on the surface of the carrier substrate 1. The hydrophilic coating on the surface of the carrier substrate 1 can enhance the adhesion and spreading ability of the cleaning liquid on the surface of the carrier substrate 1, making it easier for the cleaning liquid to enter the guide groove 101 and the contact surface between the inner shuttle blank and the carrier substrate 1, thereby improving the cleaning efficiency and effect.
[0038] Specifically, in this embodiment, the hydrophilic coating can be selected from polyvinylpyrrolidone (PVP), polyacrylamide (PAM), and polyethylene glycol (PEG), wherein:
[0039] Polyvinylpyrrolidone (PVP): Its molecular structure contains highly polar lactam groups, resulting in excellent hydrophilicity. Upon contact with water, it rapidly absorbs water, forming a hydrogel through hydrogen bonds between water molecules. Furthermore, PVP exhibits excellent bioinertness, does not participate in human metabolism, has good biocompatibility, is non-toxic, and does not irritate the skin or mucous membranes, making it widely used in the biopharmaceutical industry. Coating the surface of the substrate 1 with a PVP coating effectively enhances the adhesion and spreading ability of the cleaning solution, facilitating its flow into the guide channel 101 and the contact surface between the inner shuttle blank and the substrate 1, thereby improving cleaning efficiency and effectiveness.
[0040] Polyacrylamide (PAM): Its molecules are rich in hydrophilic amide groups, thus exhibiting excellent hydrophilic properties. Simultaneously, PAM also demonstrates excellent cell and blood compatibility, and its hydrogels have attracted attention in the fields of biomedical materials such as artificial blood vessels and artificial articular cartilage, as well as in the field of super-lubricating coatings for medical catheters. Using PAM as a hydrophilic coating on the substrate 1 can enhance the coating's hydrophilicity, allowing the cleaning solution to function better and improving the cleaning effect.
[0041] Polyethylene glycol (PEG): The presence of ether bonds and hydroxyl groups in its molecule endows it with good hydrophilicity and biocompatibility. However, when used alone, it suffers from easy detachment and short duration of hydrophilicity. If plasma technology is used to pretreat the surface of the substrate 1 before immersing it in a PEG solution to form a hydrophilic coating, studies have shown that O2- plasma treatment can extend the duration of the hydrophilic coating. After 25-30 minutes of treatment, a long-term hydrophilic surface exceeding 400 hours can be formed, which is beneficial for improving the long-term effectiveness of auxiliary cleaning of the substrate.
[0042] Specifically, in this embodiment, the edges of the carrier substrate 1 are rounded. This rounded edge structure prevents sharp edges from causing scratches to workers and also prevents accidental damage to the inner shuttle blank during placement or handling.
[0043] Specifically, in this embodiment, the bottom of the carrier substrate 1 is provided with several support feet. The support feet at the bottom of the carrier substrate 1 can support the carrier substrate 1, so that a gap is formed between the bottom of the carrier substrate 1 and the placement surface, which is conducive to the backflow of cleaning fluid and the ventilation and drying of the bottom of the carrier substrate 1, and reduces the residue of cleaning fluid at the bottom of the carrier substrate 1.
[0044] In summary, the working principle of the support plate for effectively improving the catalytic deesterification efficiency of the inner shuttle blank provided in this embodiment is as follows:
[0045] This support plate, which effectively enhances the catalytic deesterification efficiency of the inner shuttle blank, achieves high-efficiency deesterification through structural design:
[0046] The guide groove 101 on the carrier substrate 1 provides a flow channel for the cleaning fluid, allowing the cleaning fluid to flow smoothly into the contact surface between the inner shuttle blank and the carrier substrate 1, breaking the traditional flat carrier plate's bonded and closed state and eliminating cleaning dead corners.
[0047] The partition groove 102 between adjacent guide grooves 101 forms a physical separation between the billets, guiding the billets to be placed in an orderly manner and avoiding collisions;
[0048] The substrate 1 is made of corrosion-resistant material, which can resist the corrosion of cleaning solution and ensure long-term stable operation;
[0049] The hydrophilic coating enhances the adhesion and spreading of the cleaning solution on the surface of the substrate 1, thereby improving the efficiency of the cleaning solution in the guide channel 101.
[0050] The rounded edges prevent scratches and damage to the blank during operation;
[0051] The bottom support feet lift the substrate 1, creating a bottom gap that facilitates the return of cleaning solution and substrate drying, reducing residue. The synergistic effect of all components improves the efficiency and quality of catalytic deesterification.
[0052] How to use
[0053] 1. Place the substrate 1 stably inside the degreasing treatment equipment, ensuring that the bottom support feet are in stable contact with the bottom surface of the equipment, so that a gap is formed between the bottom of the substrate 1 and the surface of the equipment;
[0054] 2. With the help of the separating groove 102, the spindle blank to be degreased is placed on the upper part of each group of guide grooves 101, so that the bottom of the blank is in contact with the area of the guide groove 101.
[0055] 3. Start the degreasing treatment equipment to allow the cleaning solution to act on the surface of the substrate 1 and the blank. The cleaning solution flows into the contact surface between the blank and the substrate 1 through the guide channel 101 and is fully spread under the action of the hydrophilic coating.
[0056] 4. During the degreasing process, the separator 102 prevents the billets from colliding with each other, and the rounded corner structure at the edges avoids accidental damage during operation and processing;
[0057] 5. After degreasing is completed, turn off the equipment, remove the inner shuttle blank of the rotary hook, and the cleaning liquid flows back through the bottom gap of the support plate 1. The support plate 1 is quickly ventilated and dried under the action of the support feet.
[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
