Description

Technical Field

[0001] The utility model relates to the technical field of shaping tooling, in particular to a shaping tooling and a production line for parts with uneven thickness. Background Art

[0002] With the vigorous development of the aerospace industry, the use of high-temperature alloy aviation parts is becoming more and more widespread. However, high-temperature alloy castings are difficult to process due to their high hardness and strength. Therefore, the size requirements for high-temperature alloy castings are getting higher and higher. Castings that are scrapped due to dimensional tolerance will greatly increase the product's R&D and production costs. Therefore, it is more meaningful to shape high-temperature and alloys with uneven thickness. The qualified rate of casting dimensions can be improved through shaping tooling, which greatly reduces R&D and production costs. However, for parts of specific shapes, the requirements for shaping tooling are often different. In particular, for parts that must meet the requirements of both the position shaping of the axial end face of the part and the shaping of the circumferential size, the shaping tooling is often more complicated.

[0003] Therefore, it is urgent to design a shaping tool and a production line for parts with uneven thickness to solve the above problems. Utility Model Content

[0004] One purpose of the utility model is to provide a shaping tool, which can simultaneously shape the positions of two end faces of a part in the axial direction, and can also shape the circumference of the part. The shaping tool has a simple structure and is simple and convenient to operate.

[0005] Another object of the utility model is to provide a production line for parts with uneven thickness, which makes it more convenient and faster to shape parts with special shapes in the axial direction and the circumferential direction.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] The beneficial effects of the utility model are:

[0008] The utility model provides a shaping tool. When shaping the part of the special shape, the second annular shaping piece is first placed on the platform, and then the part is placed on the side of the second annular shaping piece away from the platform, so that the second annular shaping piece is supported on the abutting surface of the inner ring. At this time, due to the setting of the axial size of the second annular shaping piece, the free end of the circumference is in a suspended state, and then the first annular shaping piece is placed on the outer ring, so that the free end face of the outer ring abuts against the first annular shaping piece, and the hydraulic press is pressed downward, and the pressing surface of the hydraulic press abuts against the side of the first annular shaping piece away from the outer ring, and stops after descending to the required height of the free end face of the outer ring, thereby, the height of the free end face of the outer ring meets the process requirements; then, the first annular shaping piece is placed on the platform, and then Figure 2The parts in the state are placed upside down on the side of the first annular shaping piece away from the platform, so that the free end face of the outer ring abuts on the first annular shaping piece. Due to the thickness setting of the first annular shaping piece, the inner ring is in a suspended state, and then the second annular shaping piece is placed on the inner ring, and at this time, the top of the second annular shaping piece is higher than the top setting of the circumferential part. The hydraulic press presses down, and the pressing surface of the hydraulic press abuts on the top of the second annular shaping piece, and stops after descending to the height requirement of the inner ring. Therefore, the height of the inner ring meets the process requirements; then, The first annular shaping member and the second annular shaping member are removed, and at least two inner shaping members are placed on the platform, and the two adjacent inner shaping members are closely fitted, and then the parts are placed on the at least two inner shaping members, so that the inner side of the circumference is covered on the outer periphery of the circular assembly formed by the at least two inner shaping members, and the driving member drives the at least two inner shaping members to move radially until the standard size of the circumference is met and stops. Since the inner side of the circumference is closely attached to the circumference of the circular assembly, the size and surface tolerance of the inner circumference of the circumference also meet the process requirements. After the shaping of the shaping tool, the end face height, circumferential surface size and surface tolerance of the special-shaped parts all meet the requirements, and the tool structure is simple, the operation is simple, and the shaping of the parts can be completed quickly.

[0009] The utility model also provides a production line for uneven thickness parts, which includes the above-mentioned shaping tool. By adopting the above-mentioned shaping tool, the parts produced by the production line have higher precision in the axial direction and the circumferential direction, and the shaping is more convenient and fast.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] like Figure 1 and Figure 2 As shown, the part 200 includes a main body 210 and an outer ring 220, the main body 210 includes an inner ring 211, a connecting portion 212 and a circumferential portion 213 connected in sequence, the inner ring 211 is perpendicular to the axial direction of the part 200, the circumferential surface of the circumferential portion 213 extends along the axial direction of the part 200, the outer ring 220 is connected to the main body 210, and the free end face 221 of the main body 210 is parallel to the inner ring 211. The above-mentioned part 200 needs to ensure the height of the free end face 221 of the outer ring 220, the height of the plane of the inner ring 211, the roundness of the circumferential surface of the circumferential portion 213 and the parallelism with the axial direction of the part 200. It can be understood that due to the uneven thickness of the part 200, each surface is easily deformed after processing, so that the processed product cannot meet the tolerance requirements of size or surface.

[0026] In order to solve the above problems, this embodiment provides a shaping tool for shaping the above part 200 so that its axial end face meets the height requirement and the circumferential side face meets the surface tolerance requirement, and the structure is simple and the operation is simple. Figure 1-Figure 5 As shown, the shaping tool includes a first annular shaping member 10, a second annular shaping member 20 and a circumferential shaping mechanism 30, the end face of the first annular shaping member 10 can abut against the free end face 221 of the outer ring 220; the side of the inner ring 211 opposite to the free end face 221 of the outer ring 220 is abutting surface 21111, the end face of the second annular shaping member 20 can abut against the abutting surface 21111, the axial dimension of the second annular shaping member 20 is greater than the axial distance from the abutting surface 21111 to the other end of the main body 210, and ... inner ring 211 is abutting against the free end face 221 of the outer ring 220; the inner ring 211 is abutting against the free end face 221 of the outer ring 220; the inner ring 211 is abutting against the free end face 221 of the outer ring 220; the inner ring 211 is abutting against the free end face 221 of the outer ring 220; the inner ring 211 is abutting against the free end face 221 of 0 is greater than the axial distance between the abutment surface 21111 and the free end surface 221 of the outer ring 220; the circumferential shaping mechanism 30 includes a driving member 32 and at least two inner shaping members 311, at least two inner shaping members 311 are assembled into a circular component 31, the driving member 32 is configured to simultaneously drive at least two inner shaping members 311 to move radially so that the circumferential dimension of the circular component 31 meets the standard dimension of the circumferential portion 213, and the circular component 31 that meets the standard dimension of the circumferential portion 213 abuts against the inner side of the circumferential portion 213.

[0027] When the shaping tool is used to shape the part 200 of a special shape, Figure 2As shown, first place the second annular shaping member 20 on a platform (not shown), then place the part 200 on the side of the second annular shaping member 20 away from the platform, so that the second annular shaping member 20 is supported on the abutting surface 21111 of the inner ring 211. At this time, due to the setting of the axial dimension of the second annular shaping member 20, the free end of the circumferential portion 213 is in a suspended state, and then place the first annular shaping member 10 on the outer ring 220, so that the free end surface 221 of the outer ring 220 abuts against the first annular shaping member 10, and the hydraulic press is pressed downward, and the pressing surface of the hydraulic press abuts against the side of the first annular shaping member 10 away from the outer ring 220, and stops after descending to the required height of the free end surface 221 of the outer ring 220, thereby, the height of the free end surface 221 of the outer ring 220 meets the process requirements; then, as shown in FIG. Figure 3 As shown, the first annular shaping member 10 is placed on the platform, and then Figure 2 The part 200 in the state is placed upside down on the side of the first annular shaping member 10 away from the platform, so that the free end face 221 of the outer ring 220 abuts on the first annular shaping member 10. Due to the thickness setting of the first annular shaping member 10, the inner ring 211 is in a suspended state, and then the second annular shaping member 20 is placed on the inner ring 211, and at this time, the top of the second annular shaping member 20 is higher than the top setting of the circumferential portion 213. The hydraulic press is pressed down, and the pressing surface of the hydraulic press abuts against the top of the second annular shaping member 20, and stops after descending to the height requirement of the inner ring 211. As a result, the height of the inner ring 211 meets the process requirements; then, as Figure 5 As shown, the first annular shaping member 10 and the second annular shaping member 20 are removed, and at least two inner shaping members 311 are placed on the platform, and the two adjacent inner shaping members 311 are closely fitted, and then the part 200 is placed on the at least two inner shaping members 311, so that the inner side of the circumferential portion 213 is covered on the outer periphery of the circular assembly 31 formed by the at least two inner shaping members 311, and the driving member 32 drives the at least two inner shaping members 311 to move radially until the standard size of the circumferential portion 213 is met and stops. Since the inner side of the circumferential portion 213 is closely fitted to the circumferential side of the circular assembly 31, the size and surface tolerance of the inner circumferential surface of the circumferential portion 213 also meet the process requirements. After the shaping of the above shaping tool, the end face height, circumferential surface size and surface tolerance of the special-shaped part 200 all meet the requirements, and the tool structure is simple and easy to operate, and the shaping of the part 200 can be completed quickly.

[0028] It should be noted that Figure 2 , Figure 3 as well as Figure 5 The order of the three steps is not limited, and any step can be performed first.

[0029] Alternatively, if Figure 2As shown, an annular convex portion 2112 is convexly provided on one side of the abutting surface 21111, and the position where the second annular shaping member 20 abuts against the abutting surface 21111 is located inside the annular convex portion 2112. Figure 2 and Figure 3 In the shaping step, when the part 200 is placed on the second annular shaping member 20, it is more convenient to find the position. It can be understood that the inner ring 211 includes a flat portion 2111 and the above-mentioned annular convex portion 2112 convexly arranged on the flat portion, and the abutting surface 21111 is a side surface of the flat portion 2111.

[0030] Alternatively, if Figure 2 and Figure 3 As shown, the inner diameter of the first annular shaping member 10 is smaller than the inner diameter of the outer ring 220, and the outer diameter of the first annular shaping member 10 is larger than the outer diameter of the outer ring 220. Through the above arrangement, when the free end face 221 of the outer ring 220 abuts against the first annular shaping member 10, the end face of the first annular shaping member 10 can completely cover the free end face 221 of the outer ring 220, ensuring the stability of the free end face 221 of the outer ring 220 deforming with the first annular shaping member 10.

[0031] Alternatively, if Figure 4 As shown, there are three inner shaping members 311. In other embodiments, the number of the inner shaping members 311 may also be two, four, five or more, which is not limited here.

[0032] Preferably, if Figure 4 and Figure 5 As shown, each inner shaping member 311 is provided with a plurality of weight-reducing holes 3111. The labor intensity of manually carrying the inner shaping member 311 can be reduced.

[0033] Alternatively, if Figure 4 As shown, a driving hole 313 is provided at the center of the circular assembly 31 composed of at least two inner shaping members 311, and a driving member 32 can be inserted into the driving hole 313 to simultaneously drive at least two inner shaping members 311 to move radially. Through the above arrangement, a hydraulic press is also used to press down, so that the driving member 32 is inserted into the driving hole 313, and then the driving member 32 simultaneously pushes at least two inner shaping members 311 to move radially. It can be understood that, as Figure 4 As shown, each inner shaping member 311 is provided with a notch 3112 , and at least two notches 3112 form the driving hole 313 .

[0034] Preferably, if Figure 4 and Figure 5 As shown, the driving hole 313 is a tapered hole. Through the above arrangement, the driving member 32 is embedded gradually, and the impact on the inner shaping member 311 is smaller.

[0035] Specifically, the peripheral side of the driving member 32 is configured with a tapered inclined surface 321 adapted to the tapered hole. It can be understood that the angle of the tapered hole is adapted to the angle of the tapered inclined surface 321.

[0036] Alternatively, if Figure 5 As shown, when the tapered inclined surface 321 is in close contact with the inner side of the entire tapered hole, and one end of the driving member 32 is flush with the end surface of the inner shaping member 311, the circumferential dimension of the circular component 31 meets the standard dimension of the circumferential portion 213. It can be understood that when the pressing plane of the hydraulic press descends to the point where the bottom surface of the driving member 32 abuts against the platform, the circumferential shape of the circular component 31 reaches the standard value of the circumferential portion 213.

[0037] Alternatively, if Figure 5 As shown, the length of the tapered slope 321 is slightly longer than the length of the tapered hole, so that after the driving member 32 abuts against the platform, a distance is still reserved to prevent dust or debris from falling into the gap between the driving member 32 and the inner shaping member 311 during the process of the driving member 32 driving the inner shaping member 311, causing the circumferential size of the circular component 31 to become larger.

[0038] This embodiment also provides a production line for uneven thickness parts, which includes the above-mentioned shaping tool. By adopting the above-mentioned shaping tool, the parts 200 produced by the production line have higher precision in the axial direction and the circumferential direction, and the shaping is more convenient and fast.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
