Description

Technical Field

[0001] This utility model relates to the field of titanium alloy processing technology, specifically to a sintering device for titanium alloy products that reduces sintering friction. Background Technology

[0002] Titanium alloys, as a highly applicable material in the aerospace field, possess numerous significant advantages. Their specific gravity is approximately 4.5, almost half that of commonly used steel alloys with a specific gravity exceeding 7.8. Furthermore, titanium alloys exhibit high strength, with a strength-to-weight ratio far surpassing that of lightweight aluminum and aluminum alloys. Particularly in terms of temperature resistance and acid / alkali resistance, titanium alloys demonstrate a clear advantage over other commonly used metallic materials, a fact widely recognized over the past half-century.

[0003] However, the price of titanium alloy raw materials remains high due to the difficulty of the refining process. This is mainly because titanium alloys react with all the materials used in the containers for melting at high temperatures, causing contamination. Therefore, processing titanium alloy raw materials into usable billets is quite costly. This not only affects the cost of titanium alloy raw materials but also its subsequent processing. For example, subtractive machining methods reduce the utilization rate of titanium alloy billets because a large number of cutting and material removal operations result in material waste. Therefore, powder forming methods, such as pressing, powder forging, metal powder injection molding, and 3D printing in additive manufacturing, have become important processing methods for titanium alloys.

[0004] In powder processing, sintering and solidification are typically required to impart the necessary strength to the powder green part and determine its final shape. During the hot stripping process of sintering, the plastic component in the original titanium alloy feedstock is removed, and the titanium alloy particles then fuse together, causing the product to shrink. During this shrinkage, the titanium alloy rubs against the original oxide ceramic plate and small oxide ceramic supports, leading to defects such as shrinkage deformation and friction damage. Furthermore, current material handling processes often require sintering, stripping, cleaning, and coating in separate steps. Stripping often relies on manual labor or poorly adapted machinery, resulting in low efficiency and potential product damage. Cleaning is done manually, which makes it difficult to guarantee cleaning effectiveness, and excessive human intervention leads to a cumbersome and inefficient production process.

[0005] Based on this, this utility model designs a sintering device for titanium alloy products to reduce sintering friction in order to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a sintering device for titanium alloy products that reduces sintering friction.

[0007] The technical solution adopted to solve the above technical problems is:

[0008] A sintering apparatus for titanium alloy products to reduce sintering friction includes a mounting base. A conveying device for transportation is mounted on the mounting base. Multiple sets of oxide ceramic plates for placing titanium alloy green bodies are arranged on the conveying device. A first mounting frame is mounted on the conveying device. A feeding assembly for feeding and scraping sintering powder off the oxide ceramic plates is also mounted on the conveying device. A continuous vacuum sintering furnace is fixedly connected to the upper end of the first mounting frame. A heating device is fixedly mounted on the inner top surface of the right side of the first mounting frame. Symmetrical arrangement of [missing information - likely related to heating equipment] on the left and right sides of the continuous vacuum sintering furnace. Two sets of upper and lower conveying components are used to transport oxide ceramic plates between a conveying device and a continuous vacuum sintering furnace. A spraying device for spraying sintering material is fixedly installed on the lower right end face of the continuous vacuum sintering furnace. A second limiting component is installed on the continuous vacuum sintering furnace to limit the oxide ceramic plates output from the continuous vacuum sintering furnace. The upper and lower conveying components are connected to the conveying device and the second limiting component. The conveying device, the second limiting component, and the unloading component are connected to the oxide ceramic plates. Buffer blocks are fixedly installed in the middle of the left and right sides of the oxide ceramic plates.

[0009] The upper and lower conveying assembly includes a first cylinder, a second mounting frame, and a second roller conveyor. The first cylinder is fixedly installed on the upper surface of the continuous vacuum sintering furnace. The output end of the first cylinder is fixedly connected to the upper surface of the second mounting frame. The lower surface of the second mounting frame is fixedly connected to the upper surface of the second roller conveyor. The conveying rollers on the second roller conveyor are in rolling contact with the bottom surface of the oxide ceramic plate. The left side of the second roller conveyor is connected to the conveying device, and the right side of the second mounting frame is connected to the second limiting assembly.

[0010] The above technical solution allows for the application of sintering material between the oxide ceramic plate and the titanium alloy green body via a spraying device. This effectively reduces friction between the titanium alloy green body and the oxide ceramic plate during sintering, resulting in better dimensional accuracy and reduced deformation. It also minimizes surface defects caused by sintering friction, improving yield. The loaded oxide ceramic plate is conveyed to the continuous vacuum sintering furnace above via the left-side upper and lower conveying components. The sintered oxide ceramic plate is then conveyed to the lower part of the conveying device for unloading and cleaning, before being moved to the conveying device. Simultaneously, the spraying device above the conveying device sprays sintering material onto the oxide ceramic plate. After spraying, the plate passes through the right side of the first mounting frame, where a heating device on the frame dries the sprayed sintering material, causing rapid evaporation of the solvent. This allows the applied portion of the sintering material to adhere to the oxide ceramic plate. The plate is then loaded via the left side of the conveying device, achieving continuous sintering and improving production efficiency.

[0011] Furthermore, the conveying device includes a first roller conveyor and a first limiting component. The upper end face of the first roller conveyor is fixedly connected to the lower end face of the first mounting frame, and the lower end face of the first roller conveyor is fixedly connected to the upper end face of the mounting base. The conveying roller on the first roller conveyor is in rolling connection with the bottom surface of the oxide ceramic plate. The first limiting component is connected to the mounting base and the oxide ceramic plate. The second roller conveyor on the left side is connected to the first limiting component.

[0012] Through the above technical solution, the first roller conveyor drives the oxide ceramic plate to move, which facilitates the oxide ceramic plate to complete the spraying of sintering material, attachment of sintering material, and application of titanium alloy green body from right to left.

[0013] Furthermore, the first limiting component includes a first limiting frame, a first sliding rod, and a first spring. The right end face of the first limiting frame abuts against the left side face of the oxide ceramic plate. Two sets of the first sliding rod are arranged in a front-to-back pattern and fixedly installed on the upper end face of the first limiting frame and slidably connected to the left end of the mounting base. The lower end face of the left second roller conveyor abuts against the upper end faces of both sets of the first sliding rods. Two sets of the first spring are respectively sleeved on the outside of the two sets of the first sliding rods. The upper end of the first spring is fixedly connected to the inner bottom surface of the left side of the mounting base, and the lower end of the first spring is fixedly connected to the upper end face of the first limiting frame.

[0014] The above technical solution uses a first limiting frame to block and limit the oxide ceramic plates after loading the titanium alloy green body, preventing them from falling off. When the left-side upper and lower conveying components descend, the left-side second roller conveyor drives the first slide bar to slide on the mounting base. The first slide bar drives the first limiting frame to descend, releasing the leftmost oxide ceramic plate. When the oxide ceramic plates after loading the titanium alloy green body have completely moved onto the left-side second roller conveyor, the left-side second roller conveyor rises. At this time, under the force of the first spring, the first limiting frame resets, limiting the next set of oxide ceramic plates after loading the titanium alloy green body. Because buffer blocks are provided on both sides of the oxide ceramic plates, there is space between the two sets of oxide ceramic plates, which will not affect the passage of the first limiting frame. This achieves the orderly conveying of the oxide ceramic plates.

[0015] Furthermore, the upper and lower conveying assembly also includes a limiting baffle, which is fixedly installed on the outer side wall of the second mounting frame, and the inner side wall of the limiting baffle is in contact with the outer side wall of the oxide ceramic plate.

[0016] Through the above technical solution, the limiting baffle blocks and limits the oxide ceramic plate to prevent it from falling off the second roller conveyor. At the same time, the limiting baffle facilitates the unloading and cleaning of the unloading component.

[0017] Furthermore, the sintering material sprayed by the spraying equipment is a mixture of micron-sized yttrium oxide sintered powder and alcohol.

[0018] Through the above technical solution, the heat generated by the heating equipment causes the alcohol to evaporate rapidly into the surrounding environment. Then, the micron-sized yttrium oxide sintering powder can be evenly spread on the placement surface of the oxide ceramic plate. The coating of micron-sized yttrium oxide powder can effectively reduce the friction between the titanium alloy green body and the oxide ceramic plate during sintering, resulting in better product dimensional accuracy and less deformation. At the same time, it reduces product appearance defects caused by sintering friction and improves yield.

[0019] Furthermore, the second limiting component includes a second limiting frame, a second sliding rod, and a second spring. The left side of the second limiting frame is in contact with the right side of the oxide ceramic plate. Two sets of the second sliding rod are arranged in a front-to-back arrangement and fixedly installed on the lower end face of the second limiting frame. The second sliding rod is slidably connected to the right end of the continuous vacuum sintering furnace. The upper end face of the right-side second mounting frame is in contact with the lower end faces of both sets of the second sliding rod. Two sets of the second spring are respectively sleeved on the outside of the two sets of the second sliding rod. The upper end of the second spring is fixedly connected to the right bottom face of the second limiting frame, and the lower end of the second spring is fixedly connected to the upper end face of the continuous vacuum sintering furnace.

[0020] Through the above technical solution, the left side of the second limiting frame blocks and limits the oxide ceramic plate that carries the sintered titanium alloy green body. When the upper and lower conveying components on the right side rise, the second mounting frame on the right side rises and drives the second slide rod to release the second limiting frame from limiting the outermost oxide ceramic plate that carries the sintered titanium alloy green body. When the oxide ceramic plate carrying the sintered titanium alloy green body has completely moved onto the second roller conveyor on the right side, the second mounting frame on the right side descends. At this time, the second limiting frame resets under the action of the second spring and limits the next set of oxide ceramic plates carrying the sintered titanium alloy green body. Since buffer blocks are set on both sides of the oxide ceramic plate, there is space between the two sets of oxide ceramic plates, which will not affect the passage of the second limiting frame, thus realizing the orderly conveying of the oxide ceramic plates.

[0021] Furthermore, the feeding assembly includes a second cylinder, a pusher plate, a scraper, a feeding plate, and sieve holes. The second cylinder is fixedly installed at the front end of the upper right side of the mounting base. The output end of the second cylinder is fixedly connected to the upper side of the front end face of the pusher plate. The lower side of the front end face of the pusher plate is fixedly connected to the rear end face of the scraper. The lower end of the scraper is slidably connected to the upper end face of the oxide ceramic plate. The scraper is made of elastic material. The feeding plate is fixedly installed at the rear right side of the mounting base. Multiple sets of sieve holes are opened on the front side of the feeding plate.

[0022] Through the above technical solution, the second cylinder drives the pusher plate to push down the sintered titanium alloy green body. At the same time, the pusher plate drives the scraper to clean the sintered material on the oxide ceramic plate placement surface to facilitate subsequent spraying. The sintered titanium alloy green body is discharged through the unloading plate, and the cleaned sintered material is screened out through the sieve holes on the unloading plate. This achieves simultaneous unloading and cleaning, and can screen out 1-micron yttrium oxide sintered powder after cleaning.

[0023] Furthermore, the oxide ceramic plate is a zirconia plate or an alumina plate.

[0024] The beneficial effects of this utility model are as follows: (1) The sintering material can be sprayed between the contact surface of the oxide ceramic plate and the titanium alloy green body by the spraying equipment, which can effectively reduce the friction between the titanium alloy green body and the oxide ceramic plate during sintering, resulting in better product dimensional accuracy and less deformation. At the same time, it reduces product appearance defects caused by sintering friction and improves yield. (2) The oxide ceramic plate can be moved by the conveying device, and the sintering material can be sprayed onto the oxide ceramic plate by the spraying equipment above the conveying device. After the spraying is completed, the plate passes through the right side of the first mounting frame and is heated by the heating equipment set on the first mounting frame. The sprayed sintering material is dried to promote rapid evaporation of the solvent, allowing the sintering material to adhere to the oxide ceramic plate. Then, the titanium alloy green body is fed through the left side of the conveyor device. After that, the oxide ceramic plate with the material is conveyed to the continuous vacuum sintering furnace above for sintering through the upper and lower conveying components on the left side. After sintering, the oxide ceramic plate carrying the sintered titanium alloy finished product is conveyed to the lower side through the upper and lower conveying components on the right side for unloading and cleaning. After the oxide ceramic plate is cleaned, the sintering material is sprayed again. By repeating the above process, continuous sintering is achieved, which improves production efficiency.

[0041] The upper and lower conveying assembly 5 includes a first cylinder 51, a second mounting frame 52, and a second roller conveyor 54.

[0044] The feeding assembly 8 includes a second cylinder 81, a pusher plate 82, a scraper 83, a feeding plate 84, and sieve holes 85.

The feeding plate 84 is fixedly installed at the rear right side of the mounting base 1. Multiple sets of sieve holes 85 are opened on the front side of the feeding plate 84. The oxide ceramic plate 9 is a zirconia plate or an alumina plate.

[0045] In use, the oxide ceramic plate 9 can be driven by the first roller conveyor 21, and then the sintering material can be sprayed between the contact surface of the oxide ceramic plate 9 and the titanium alloy green body by the spraying equipment 6. The spraying equipment 6 is an ultrasonic spraying equipment, which is a mature existing technology. Then, the first roller conveyor 21 drives the oxide ceramic plate 9 past the right side of the first mounting frame 3. The sintering material that has been sprayed is dried by the heating equipment set on the first mounting frame, which promotes the rapid evaporation of the solvent (alcohol). Then, the 1-micron yttrium oxide sintering powder can be evenly spread on the placement surface of the oxide ceramic plate 9. The heating equipment is an air heater, which is a mature existing technology.

[0046] Then, when the oxide ceramic plate 9 is transported to the left side of the first roller conveyor 21, the titanium alloy green body is fed in. The first roller conveyor 21 continues transporting, and the oxide ceramic plate 9 with the titanium alloy green body is blocked and limited by the first limit frame 221 to prevent it from falling off. Then, the first cylinder 51 on the left side drives the second mounting frame 52 to lower the second roller conveyor 54 on the left side. The second roller conveyor 54 on the left side drives the first slide rod 222 to slide on the mounting base 1. The first slide rod 222 drives the first limit frame 22... 1. The leftmost oxide ceramic plate 9 is released when the lowering mechanism is activated. The oxide ceramic plate 9, after being loaded with the titanium alloy green body, moves to the second roller conveyor 54 on the left and is blocked and limited by the limiting baffle 53. Then the second roller conveyor 54 on the left rises. At this time, the first limiting frame 221 is reset under the force of the first spring 223, and the next set of oxide ceramic plates 9 after being loaded with the titanium alloy green body is limited. Since buffer blocks are provided on both the left and right sides of the oxide ceramic plate 9, there is space between the two sets of oxide ceramic plates 9 and it will not affect the passage of the first limiting frame 221.

[0047] When the second roller conveyor 54 moves to the left side of the upper continuous vacuum sintering furnace 4, it transports the oxide ceramic plate 9 containing the titanium alloy green body to the continuous vacuum sintering furnace 4 for sintering. Then, the left side of the second limiting frame 71 blocks and limits the oxide ceramic plate 9 that has been sintered. Then, when the first cylinder 51 on the right drives the second mounting frame 52 to raise the second roller conveyor 54 on the right, the rising of the second mounting frame 52 drives the second slide bar 72 to release the second limiting frame 71 from the outermost sintered plate. The oxide ceramic plate 9, which is the carbon substrate of the titanium alloy green body, is positioned and moved to the second roller conveyor 54 on the right side after the titanium alloy green body has been sintered. It is then blocked and limited by the limiting baffle 53. Then the second roller conveyor 54 on the right side descends. At this time, the second limiting frame 71 is reset under the action of the second spring 73, and the next set of oxide ceramic plates 9 that are sintered titanium alloy green bodies are limited. Since buffer blocks are provided on both the left and right sides of the oxide ceramic plate 9, there is space between the two sets of oxide ceramic plates 9, which will not affect the passage of the second limiting frame 71.

[0048] When the second roller conveyor 54 descends to its lowest point, the second cylinder 81 drives the pusher plate 82 to push the sintered titanium alloy green body off the oxide ceramic plate 9. At the same time, the pusher plate 82 drives the scraper 83 to clean the sintered material on the oxide ceramic plate 9 for subsequent spraying. The sintered titanium alloy green body is discharged through the unloading plate 84. At the same time, the 1-micron yttrium oxide sintered powder is screened out through the sieve holes 85 on the unloading plate 84. Then, the second roller conveyor 54 transports the unloaded and cleaned oxide ceramic plate 9 to the right end of the first roller conveyor 21. The first roller conveyor 21 then transports the unloaded and cleaned oxide ceramic plate 9 to the spraying equipment 6 for sintered material spraying, thus completing the cycle. An atmosphere can be introduced into the continuous vacuum sintering furnace during sintering.
