Problems solved by technology
[0002] The existing solution to aluminum alloy die castings is to carry out shaping after casting. However, due to the internal stress problem after shaping, it is released during shot blasting and processing, resulting in stress deformation of the product as the stress is gradually released, and the size is unqualified. It is easy to cause product damage, increase the cost, and the quality is not easy to control
There are two reasons for the stress, one is the stress caused by solidification and shrinkage during casting, and the other is the cutting stress during the processing process, and the product structure is irregular, so it is difficult to control the force applied during shaping, and the quality of shaping Large, deformation cannot be completely avoided

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] A method for manufacturing an aluminum alloy servo housing of an automobile steering gear support seat of the present invention comprises the following steps:
[0022] Step 1) After designing the product, set up a die-casting mold, add a stretching rib 2 at the opening of the product body 1, wherein the thickness of the stretching rib is 1.5-2 mm, and set up a slag discharge groove on the stretching rib 2 3. Then die-casting production is carried out through die-casting equipment; the thickness of the tensile ribs is set between 1.5-2mm, which can ensure the smoothness of the filling process...

Abstract
The invention discloses a manufacturing method of an aluminum alloy servo housing of a supporting seat of an automobile steering engine. The method comprises the steps of 1) designing a product; arranging a die-casting die; additionally arranging stretching ribs being 1.5-2mm at an opening of a product body; forming slagging-off grooves in the stretching ribs; and then performing die-casting production through a die-casting device; 2) cleaning the product after die-casting; 3) processing the product surface through a shot blasting machine; and 4) modifying the surface of the product through acutter after the surface processing; and then cutting off the stretching ribs. According to the method, the stretching ribs are additionally arranged on the product body 1, and the slagging-off grooves are formed in the stretching ribs, so that the inner quality of the stretching ribs is ensured, and the strength of the stretching ribs ensures the deformation force of the product body in deforming; in addition, the stretching ribs apply force to the product by supporting, clamping and compressing, and thus the product is prevented from compressing and deforming.
Description
technical field [0001] The invention relates to the field of automobile production, in particular to a method for manufacturing an aluminum alloy servo casing of an automobile steering gear support seat. Background technique [0002] The existing solution to aluminum alloy die castings is to carry out shaping after casting, but after shaping, due to internal stress problems, it is released during shot blasting and processing, resulting in stress deformation of the product as the stress is gradually released, and the size is unqualified, and the shaping is done after processing. It is easy to cause product bruising, cost increase, and quality is difficult to control. There are two reasons for stress, one is the stress caused by solidification and shrinkage during casting, and the other is the cutting stress during processing, and the product structure is irregular, it is difficult to control the force applied during shaping, and the quality of shaping is fluctuating Large, d...
