Description

Technical Field

[0001] The utility model belongs to the technical field of blank cooling devices, and in particular relates to a blank cooling device for steel back casting. Background Art

[0002] Cast steel back is one of the components of brake pads. At present, bead brakes are widely used in the market, and the high-strength friction materials on almost all bead brake pads are sintered on a steel plate, which moves freely in the bayonet under the push of the brake cylinder. Because the steel plate is behind the friction pad, everyone calls it steel back. Steel back is generally designed with steel punches and holes for easy installation on the card. Steel back has a turning point: the steel plate material is relatively thick (generally 4-6mnm), and there are more process steps. In recent years, with people paying more and more attention to automobile safety, major car manufacturers must undergo more severe road tests and repeated demonstrations before the brake system can be officially applied to major cars. The quality of the brake system, in addition to the quality of the grinding block, is the most important thing. The steel back behind the friction block, so the quality of the steel road is directly responsible for the safety of the car and the driver and passengers, and is directly related to the quality, reputation, and sales of the car.

[0003] Cast steel back is mainly made of steel blanks, and billet cooling is a very important process in the steel industry, which will directly affect the quality and performance of the product. The cooling process of the steel back casting blank will affect its mechanical properties. If the cooling speed is too fast, it may cause the internal stress of the billet to increase, thereby reducing the toughness and strength of the billet; if the cooling speed is too slow, it will affect the improvement of the billet strength. Therefore, it is necessary to set up a steel back casting blank cooling device that is easy to control the cooling progress. Utility Model Content

[0030] In the embodiment of the present case, it is necessary to fill the cooling liquid in the cooling box 1 in advance. The staff controls the operation of the opposite displacement component 7 according to the size of the steel back blank to be cooled. The opposite displacement component 7 drives the two electric cylinders 8 to move toward each other, and the two U-shaped blank placement plates 803 move toward each other and splice until they are suitable for placing the steel back blank. Then, the output ends of the two electric cylinders 8 are controlled to drive the rectangular long block 801, the vertical support rod 802 and the U-shaped blank placement plate 803 to move downward until the U-shaped blank placement plate 803 and the placed steel back blank are immersed in the liquid of the cooling box 1. At this time, the first cooling is performed;

[0031] Then the water-cooled radiator 201 is controlled to run, the water-cooled radiator 201 cools the liquid in the inner cavity of the liquid-cooled outer box 2, and the cooled liquid in the inner cavity of the liquid-cooled outer box 2 exchanges heat with the outer wall of the cooling box 1 to cool the heated liquid in the cooling box 1, and the liquid in the cooling box 1 after heat exchange and cooling further cools the steel back blank, and at the same time, the air cooler 4 is turned on, and the air cooler 4 blows cold air into the air-cooled outer box 3 to air-cool the outer wall of the liquid-cooled outer box 2, thereby promoting further cooling of the liquid-cooled outer box 2 and the cooling box 1.
