Embodiment Construction

[0021] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0022] Casting heat treatment cooling device of the present invention, as figure 1 As shown, including a platform plate 1, a cooling drum 11 is provided on the platform plate 1, and a hopper 2 for storing castings is provided at the front end of the cooling drum 11. The hopper 2 is controlled by a traction device to pour the castings in the hopper 2 into the cooling drum In 11, the cooling water path injects cooling water into the cooling drum 11 to cool the casting, and the cooling water flow and water flow can be controlled by controlling the water valve.

[0023] In the heat treatment process of castings, annealing is to heat the workpiece to an appropriate temperature, keep it warm and then slowly cool it. Prepare. Normalizing is to heat the workpiece to a suitable temperature and then co...

Abstract

The invention discloses a casting heat treatment cooling device. The casting heat treatment cooling device comprises a platform board (1) and a cooling drum (11) arranged on the platform board (1); the front end of the cooling drum (11) is provided with a hopper (2) used for storing castings, and the hopper (2) is controlled by a traction device to pour the castings in the hopper (2) into the cooling drum (11). The casting heat treatment cooling device further comprises a cooling water way which is communicated with the interior of the cooling drum (11), and a control water valve used for controlling the water flow connection and disconnection and the water flow size is arranged in the cooling water way. According to the casting heat treatment cooling device, use is convenient, the cooling treatment technology can be determined according to the performance of the castings, the cooling speed can be controlled, the cooling effect is good, the structural performance of casting products can be greatly improved, the product quality can be improved, and large-scale application and popularization can be achieved.

Description

technical field [0001] The invention belongs to the technical field of machining, and more specifically relates to a casting cooling device for heat treatment. Background technique [0002] Heat treatment refers to a metal in which the chemical composition and structure of the surface or interior of the material are changed by means of heating, heat preservation and cooling in a solid state to obtain the required properties. Thermal treatment process generally comprises heating, insulation, three processes of cooling, has only two processes of heating and cooling sometimes. For some small castings produced in batches, the castings that have been heated and kept warm are cooled. Cooling is an indispensable step in the heat treatment process. The cooling method is different due to different processes. The main method is to control the cooling rate. The slowest, normalizing has a faster cooling rate, and quenching has a faster cooling rate. Affected by the external environmen...
