Description

Technical Field

[0001] The invention relates to the technical field of automobile wheel hub brake disc processing, and in particular to an automobile wheel hub processing system. Background Art

[0002] Carbon ceramic brake discs are made of a mixture of heated plastic resin and chopped carbon fiber. They have broad application prospects in high-energy braking fields such as automobiles, high-speed trains, and airplanes. They have a longer lifespan than ordinary cast iron brake discs, and have a longer production cycle and higher cost. The pre-production process of carbon ceramic brake discs mainly includes pouring the material into a brake disc-shaped mold, and then manually passing through multiple holes in the mold leading to the center of the circle, so that there are multiple air ducts on the circumference of the manufactured brake disc, so that air convection can be passed through the air ducts during driving to achieve the purpose of heat dissipation, and then the material in the mold is pressed to compact it; Since there are multiple cavities in the mold, it is easy for materials to accumulate in the cavities when feeding, thus affecting subsequent production work. At the same time, the materials in the mold are often not in a relatively flat state for subsequent pressing work, resulting in more gaps between the materials in the mold, reducing the quality of the finished brake disc. In addition, during the pressing process, due to the gap between the mold and the pressing device, it is easy to cause powder explosion, resulting in a worse working environment. Meanwhile, in the process of using a plurality of holes leading to the center of a circle in a mold to form an air duct in the prior art, the manual processing is complicated and consumes a lot of labor, and the mold is heavy, which can easily cause personal injury and reduce work efficiency.

DETAILED DESCRIPTION

Example

The first material cutting is then pressed by the pressing system to reduce the gaps between the materials in the brake disc mold 3. The mold feeding system then feeds the brake disc mold 3 for a second time. At this time, the material cutting amount reaches the required amount for the brake disc. At the same time, the mold feeding system inserts the material required for making the air duct into multiple holes leading to the center of the circle. The residual material collection system then scrapes and collects the residual material on the upper surface of the brake disc mold 3 during the material cutting process, thereby reducing resource loss. The pressing system then presses the second material cutting. At the same time, the pressing system prevents powder explosion caused by the gap between the mold and the material during the pressing process, thereby reducing dust in the working environment and improving comfort.

[0019] In the prior art, the cavity in the mold is prone to material accumulation, and the material is often unable to be in a relatively flat state for subsequent pressing work. There are gaps between the materials in the mold, and the gaps are prone to cause powder explosion during pressing. In view of this, the present invention proposes an automobile wheel hub processing system. When the present invention is working, the brake disc mold 3 and the mold lower pressure ring 4 are manually placed on the transmission system first, and then the first guide rail 2 drives the transmission system, the brake disc mold 3 and the mold lower pressure ring 4 to move to the bottom of the mold feeding system, and then the mold feeding system performs a first feeding of the brake disc mold 3, and the feeding amount position is below the cavity in the brake disc mold 3. At the same time, the mold feeding system can block the cavity in the brake disc mold 3 to prevent excessive material from accumulating in the cavity during the feeding process, affecting subsequent work, and then the first guide rail 2 drives the transmission system, the brake disc mold 3 and the mold lower pressure ring 4 to move to the bottom of the pressing system, and the pressing system presses the first feeding, thereby reducing the gap between the materials in the brake disc mold 3, and the pressing system pulls out the material blocking the cavity in the brake disc mold 3, and then the first guide rail 2 drives it to move again to the bottom of the mold feeding system, and the material required for making the air duct is manually placed on the mold feeding system, and then the material required for making the air duct is inserted into the cavity through the mold feeding system. There are multiple holes leading to the center of the circle. At this time, the mold feeding system pulls out the remaining blocking material, and then the mold feeding system performs secondary unloading on the brake disc mold 3, and the unloading amount reaches the required amount for the brake disc. Then the first guide rail 2 drives the transmission system, the brake disc mold 3 and the mold lower pressure ring 4 to move to the bottom of the residual material collection system, and the residual material collection system descends to scrape and collect the residual material on the upper surface of the brake disc mold 3 during the unloading process, thereby reducing the loss of resources, and then the pressing system presses the second unloading. At the same time, the pressing system prevents the explosion of powder caused by the gap between the mold and the mold during the pressing process, thereby improving the working environment. During the feeding process, the mold feeding system can support the mold lower pressure ring 4 to prevent it from sliding down and affecting subsequent work. At the same time, the residual material collection system presses down the mold lower pressure ring 4 during the descent process to complete the fixation of the mold. The entire carbon ceramic brake disc pre-production process only requires one person to replenish the materials required for making the air duct, which is easy to operate and greatly improves the work efficiency.
