Description

Technical Field

[0001] The utility model relates to the technical field of casting production, in particular to a casting correction device. Background Art

[0002] Large, thin-walled, complex aluminum alloy shell castings (wall thickness 4mm to 30mm) in the aerospace field are generally produced by sand mold low-pressure casting. Sand mold low-pressure casting can improve the density and mechanical properties of castings. With the increase in production demand, the complexity of castings is getting higher and higher, and the dimensional accuracy and surface quality of castings need to be guaranteed. Castings may be deformed during casting, heat treatment and processing. These deformations may be caused by various factors, such as casting structure limitations, high alloy strength, uneven cooling rate, casting stress, etc. Deformed castings cannot meet design requirements, affect their functions and appearance, and may even cause castings to be scrapped and increase production costs. Therefore, castings need to be corrected to correct these deformations to ensure that the size, shape and performance of the castings meet the specified standards and requirements.

[0003] Correction can be done in different ways, including cold correction and hot correction. Most existing correction methods for aluminum alloy castings use cold correction. After demolding, in order to reduce deformation of longer castings, the castings will be hung on a rack and gravity will be used to reduce the deformation of the castings. However, due to the long length, the castings will produce different degrees of warping deformation in different directions due to the different positions of the internal lining plates during the cooling process. The existing processing method is to perform hydraulic correction through a hydraulic press after cooling. However, due to the large number, the correction efficiency is not high, and since the castings have been cooled to room temperature, the correction time is long. During the correction process, the castings will crack or break, affecting product quality. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art that the correction time of castings in the molding process is long and the efficiency is low, and provides a casting correction device.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a casting correction device, comprising a plurality of support plates arranged along the length direction of the casting body, wherein one support plate is arranged along each side of the casting body, and a plurality of mounting holes are arranged on the support plates, wherein radially movable adjustment rods are arranged in the mounting holes, and an adjustment block abutting against the casting body is arranged at the end of the adjustment rod, and a locking device for fixing the mounting position is arranged on the outer side of the support plate.

[0006] Furthermore, the support plate is a rectangular plate, and the mounting holes are round holes and waist-shaped holes arranged on the support plate.

[0007] Furthermore, the adjusting rod is a threaded rod, and a locking nut is screwed onto the threaded rod.

[0008] Furthermore, a spherical head is provided at one end of the adjusting rod connected to the adjusting block, and a clamping seat cooperating with the spherical head is provided on the adjusting block.

[0009] Furthermore, the locking device includes a positioning plate abutting against the outer side of the support plate, two positioning plates are relatively arranged, the inner side of the positioning plate is provided with a clamping groove, the outer side of the positioning plate is provided with a waist-shaped hole connected to the clamping groove, two clamping plates are relatively arranged between the two clamping grooves, and clamping rods are relatively arranged on the outer sides of the two clamping plates, and the clamping rods are screwed to the outer wall of the clamping groove.

[0011] Furthermore, the positioning plates and the pressing plates are arranged in multiple groups along the length direction of the casting body.

[0012] The beneficial effects of the embodiments of the utility model are as follows: the clamping plate and the clamping groove are provided with various lengths, and support plates of different widths are selected with positioning plates and clamping plates of different lengths.

[0017] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0018] See also Figures 1 to 3 The utility model discloses a casting correction device, which includes a plurality of support plates 2 arranged along the length direction of the casting body 1, and each of these support plates 2 is arranged along the side of the casting body 1 to provide stable support. Each support plate 2 is provided with a plurality of mounting holes 201, and a radially movable adjustment rod 101 is arranged in these mounting holes 201. The end of the adjustment rod 101 is provided with an adjustment block 102 abutting against the casting body 1, so that when the adjustment rod 101 moves radially, the casting can be accurately adjusted and corrected by the adjustment block 102. The adjustment rod 101 adopts a threaded rod design, and a locking nut is screwed on it. By rotating the locking nut, the adjustment rod 101 can be fixed and locked, and the pressure on the casting body 1 can be adjusted so that the bending degree of the casting body 1 is gradually restored. The adjustment is adjusted by the rotation depth of the locking nut, so that the specific degree of adjustment can be accurately controlled, and it is also ensured that the adjustment rod 101 can maintain a stable position during the adjustment and correction of the casting.

[0019] In order to enhance the connection stability and adjustment flexibility between the adjustment block 102 and the adjustment rod 101, a spherical head is provided at one end where the adjustment rod 101 is connected to the adjustment block 102, and a snap-fit ​​seat that cooperates with the spherical head is provided on the adjustment block 102. This design allows the adjustment block 102 to be rotated and fine-tuned within a certain range to adapt to castings of different shapes and sizes, meet different gradual adjustment requirements, and increase the use environment during adjustment.

[0020] The support plate 2 is a rectangular plate, and the mounting hole 201 is a round hole and a waist-shaped hole 303 set on the support plate 2. This design not only meets the stability of the structure, but also makes the installation and adjustment of the adjustment rod 101 more convenient. It is suitable for castings of different types. The mounting hole 201 at a suitable position is selected according to the shape of the casting. It has a wide adjustment surface and strong applicability.

[0021] A locking device for fixing the installation position is provided on the outer side of the support plate 2 , and the locking device includes a positioning plate 3 abutting against the outer side of the support plate 2 . Two positioning plates 3 are relatively provided, and a snap-in groove 302 is provided on the inner side thereof. Two clamping plates 301 are arranged relatively between the two clamping grooves 302. The clamping plates 301 and the clamping grooves 302 are arranged with various lengths. The support plates 2 of different widths are selected with positioning plates 3 and clamping plates 301 of different lengths. The outer side of the clamping plate 301 is relatively arranged with a clamping rod 305. The clamping rod 305 is screwed with the outer wall of the clamping groove 302. By rotating the clamping rod 305, the clamping plate 301 can be driven to move inward, so as to clamp and fix the support plate 2. Adjusting bolts 304 are arranged at both ends of the clamping plate 301, and the adjusting bolts 304 pass through the waist-shaped holes 303 on the positioning plate 3. This design allows the clamping plate 301 to fix the support plate 2 while also being fine-tuned by the adjusting bolts 304 to adapt to support plates 2 of different widths.

[0022] In order to meet the correction requirements of castings of different lengths, multiple groups of positioning plates 3 and clamping plates 301 are arranged along the length direction of the casting body 1. The arrangement of multiple groups of positioning plates 3 and clamping plates 301 makes the casting correction device suitable for castings of different lengths, thereby improving its applicability and flexibility.

[0023] When in use, the casting still has residual temperature after demoulding. The support plate 2 provides a support point, and pressure is applied to the bend through the adjustment plate and the adjustment rod 101 to reset the casting body 1 and correct it, thereby achieving accurate correction and stable fixation of the casting. At the same time, the device also has the advantages of simple structure, easy operation, strong applicability, etc., and can be widely used in the field of casting processing.
