Description

Manufacturing method of large-size ceramic part with complex surface
Technical Field
The invention belongs to the technical field of ceramic processing, and particularly relates to a manufacturing method of a large-size ceramic part with a complex shape surface.
Background
The ceramic material has the characteristics of high hardness, high brittleness and low fracture toughness, so that the surface processing, particularly the processing of a curved surface, of the sintered and molded ceramic material is very difficult. The common ceramic processing methods at present comprise traditional machining, ultrasonic processing, electric processing, laser processing and grinding processing.
The traditional machining refers to turning by using a superhard cutter, and the phenomenon that the cutter is damaged easily due to serious cutting heat in the cutting process is easily caused; during the processing, the ceramic material is easy to generate defects such as pits, openings and cracks on the surface under the action of cutting force; and the cutting amount is usually small due to the limitation of the cutter, so that the processing efficiency is extremely low. However, the processing methods such as ultrasonic processing, electric processing, laser processing, and grinding have respective limitations, for example, the application range is small, and defects are easily generated on the surface of the ceramic. It is known that it is very difficult to complete the outer surface shape of the ceramic, especially the processing of curved surfaces, by removing material after the ceramic green body is sintered.
Therefore, under the condition of meeting the machining allowance, when the ceramic green blank is pressed, the ceramic green blank is made to fit the shape of the target part as much as possible, so that the material removal amount of the surface of the sintered ceramic part is reduced, and the machining difficulty is reduced.
The forming process of the ceramic green body before firing mainly comprises dry forming and wet forming, and the traditional wet forming process such as tape casting, gel injection molding, injection molding and the like can realize the forming of complex ceramic parts to a certain extent. However, gel casting and injection molding processes require special molds, are high in cost and are not suitable for small-batch individual production. Although the casting forming process can manufacture parts with complex shapes by laminating casting sheets layer by layer, the process is complicated, the step effect of the prepared parts is obvious, and the surface quality of the parts is greatly reduced.
Therefore, when a ceramic blank having the same shape as the target part and a size satisfying the design margin is obtained from the blank, the problems of excessive cost and complicated molding steps occur, and the method is not suitable for small-batch or customized production of ceramic parts.
The inventor thinks that the ceramic green body has the problems of reducing production cost and process steps and difficult control of deformation after sintering during the forming of the ceramic green body, so that the ceramic green body cannot be accurately fitted with the shape and the size of a target part. When the sintered ceramic blank is processed, in order to reduce the material removal amount, the ceramic blank needs to be accurately fitted with the shape and size of a target part. In summary, in different stages of ceramic manufacturing, there are different requirements for the shape and size of the ceramic blank, which causes technical contradiction and makes it difficult to achieve balance between the two.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a method for manufacturing a large-size ceramic part with a complex profile, which can solve the technical contradiction between the requirements on the shape and the size of a ceramic green body by reducing different working procedures before and after sintering of ceramic.
In order to achieve the purpose, the invention adopts the following technical scheme: a method for manufacturing a large-size complex-shaped surface ceramic part comprises the following steps:
step 1, pressing a ceramic blank meeting the allowance of a set size according to the size of a target part, wherein the shape of the ceramic blank is required to be determined before pressing, the volume required when the ceramic blank forms a minimum cylinder enveloping the target part is set to be a first numerical value, and the volume required when the ceramic blank forms a minimum cuboid enveloping the target part is set to be a second numerical value; and taking the shape corresponding to the smaller one of the first numerical value and the second numerical value to finish the pressing of the ceramic green body.
Step 2, preprocessing a ceramic green body: and if the ceramic green body is a cylinder, processing the ceramic green body into the minimum cylinder step shaft of the envelope target part by adopting a turning mode.
If the ceramic green body is a cuboid, the ceramic green body is processed into a minimum enveloping body structure enveloping the target part by adopting a milling method.
And 3, sintering the preprocessed ceramic green body to obtain the ceramic part.
And 4, finishing the fine reference processing in the ceramic part by adopting a diamond turning tool or a diamond electroplating grinding head.
And 5, roughly machining the complex outer surface of the ceramic part on a milling machine by using an electroplating diamond grinding head.
And 6, performing finish machining on the complex outer surface of the ceramic part by using a diamond grinding head.
Further, the ceramic green body is pressed by adopting a static pressure forming or dry pressing forming method.
Further, the size allowance between the ceramic green body and the target part is larger than the set size allowance.
Further, after the ceramic green body is turned into a minimum cylindrical step shaft, process holes are prefabricated at two ends of the minimum step shaft.
Further, in step 4, if the ceramic green body is a cylinder, performing precision reference machining on the outer circle of the minimum cylindrical step shaft, taking the precisely machined outer circle as a precision reference, and preparing for next external surface milling. If the green body is a cuboid, a diamond electroplating grinding head is used for fine-reference processing.
And further, spraying cooling liquid on the outer surface of the ceramic part during milling by using an electroplating diamond grinding head in the step 5 or milling by using a diamond grinding head in the step 6.
The invention has the beneficial effects that:
according to the shape of the ceramic part to be processed, the ceramic blank is pressed into a cylinder or a cuboid, and the pressed ceramic blank has only the two shapes, so that a mould for fitting the shape and the size of the ceramic part is not required to be designed, and the process and the cost for forming the ceramic blank are greatly reduced.
By adopting the mode of turning or milling before sintering the ceramic green body, under the condition that the ceramic green body can envelop the ceramic part, the material before sintering the ceramic green body is reduced, the material removal amount on the surface of the sintered ceramic part is reduced, and the difficulty in surface processing of the ceramic part is simplified.
The electroplated diamond grinding head is adopted to process the ceramic, so that the processing efficiency is greatly improved, the phenomena of edge breakage, cracking and the like in the processing process are well inhibited, and the surface quality of the processed surface is improved. The processing process does not need a special machine tool, and the processing cost is low, the efficiency is high, and the ceramic parts can be widely applied.

The minimum machining allowance of 20mm is reserved between the ceramic green body formed by pressing and the shape of the target part 1.
Step 2, preprocessing the pressed ceramic green body: the pressed ceramic green body has certain mechanical strength, and can be conveniently machined by using a lathe or a milling machine according to different formed shapes. And (3) machining the cylindrical ceramic blank 2 into a cylindrical step shaft 4 wrapping the target part 1 by using a lathe according to the shape requirement of the final workpiece, wherein the minimum allowance between the cylindrical step shaft 4 and the shape of the target part 1 is larger than 10 mm. Meanwhile, process holes for subsequent turning and positioning are machined at the top end and the bottom end of the cylindrical step shaft 4.

Meanwhile, steps are reserved at the top end and the bottom end of the frustum pyramid-shaped workpiece 5 and are used as a reference for subsequent processing.
The processed ceramic green body is subjected to next sintering, the size shrinkage is inevitable along with the densification of the ceramic in the sintering process, and the shrinkage deformation is uncontrollable, so that the processing allowance is necessary to be reserved.
And 3, sintering the ceramic green body: and (4) preprocessing the ceramic blank with enough processing allowance in the previous step, and sintering the ceramic blank according to the sintering requirement of the corresponding ceramic material in the sintering process.
And 4, processing of a fine standard: and (3) performing finish machining on the step shaft at the lowest layer by using a diamond lathe tool to machine a cylindrical shape with the diameter of 20mm to form a finish reference by using the fabrication hole prefabricated in the previous step as a positioning position on the lathe.

In a typical machining case, after the machining parameters are used for continuous machining for 10 hours, the cutter is not obviously abraded, the machining process is stable, and the phenomenon of edge breakage of a workpiece is avoided.
Compared with the traditional method for processing the commercial yttria-stabilized zirconia ceramics by using the diamond blade, the service life of the cutter is obviously prolonged. Compared with turning, the material removal efficiency is improved by 5000 times. In the machining process, the material removing mode is actually grinding machining, the cutting force is much smaller than that of milling, and the damage to a material matrix is smaller.
