Description

Technical Field

[0001] The utility model relates to a casting shaping mechanism, in particular to a heat treatment and shape correction mechanism for the cavity of a casing casting, belonging to the technical field of casting shape correction tooling. Background Art

[0002] The structures of high-performance complex aluminum / magnesium alloy casting casings show an overall and complex trend. Taking the intake casing of the engine flow channel as an example, the product forms a sphere with a multi-segment circular ring structure, having unique design advantages and challenges. Due to the small number of support points, the overall structure is prone to deformation when facing external pressure or load. With a wall thickness of only 2.5 mm, while ensuring lightweight, the load-bearing capacity of the product is limited. Therefore, the deformation amount in the flow channel area is relatively large during the post-treatment operation.

[0003] Traditionally, the shaping of castings after casting is carried out by skilled workers using a wooden hammer or a rubber hammer to strike the castings. Manual shape correction has low efficiency and the shaping effect is not significant. Tools generally have problems of small contact area and uneven force application. A too small contact area means that there are limited contact points between the tooling and the workpiece, and the force applied to the workpiece cannot be evenly dispersed. In this case, local high-pressure areas are likely to cause internal cracks or damage to the product, reducing the overall performance of the product. When manually shape-correcting the product, it is easy to affect the wall thickness uniformity or cause structural changes to the product due to uneven force application, resulting in out-of-tolerance dimensions and cracks generated by knocking.

[0004] The intake casing inner cavity flow channel has high precision requirements. The structure of the flow channel not only needs to make the fluid flow more smoothly, but also must ensure that the dimensional accuracy meets strict industry standards. High-precision dimensional control can ensure uniform fluid flow velocity in the flow channel, avoiding the generation of vortex phenomena, thereby improving the performance and stability of the product.

[0005] When dealing with arc structures and special-shaped curved surfaces with complex shape trends, the complex geometric shapes of the blades inside the cavity and the inner flow channel surface make it difficult to effectively prevent deformation during the production and shape correction of the product. At the same time, the overall structure lacks convenient adjustment means and it is difficult to achieve ideal accuracy and stability. Summary of the Utility Model

[0012] A square box, with an open upper end and a closed bottom wall, the upper end of the height adjustment stud passes through the center of the bottom wall of the square box and is locked by a height adjustment lock nut.

[0013] A shape correction support screw, horizontally inserted into the centers of the upper parts of the four walls of the square box and locked on the corresponding side walls of the square box by a support rod lock nut.

[0014] A casting detection and shape correction block, the vertical walls on the back are respectively fixedly connected to the outer ends of the corresponding shape correction support screws, and the arc-shaped outer walls respectively abut against the inner walls of the cavity of the casing casting and match with each other.
