Description

Technical Field

[0001] The utility model belongs to the technical field of quenching equipment, in particular to a metal quenching equipment. Background Art

[0002] Metal quenching equipment is one of the key equipment used in the heat treatment process of metal materials in the field of industrial heat treatment. It is mainly used to complete the quenching process, that is, to quickly cool the metal workpiece that has been heated to above the critical temperature, so that its internal structure is transformed into martensite or other required structures, so as to obtain the required physical and mechanical properties, such as high strength, high hardness, good wear resistance and toughness, etc. In the prior art, a water tank is usually fixed in the middle of one side of the quenching box, and a water pipe is connected to the upper end of the water tank. The water pipe extends into the interior of the quenching box and is connected to a nozzle so as to quench the workpiece. However, in this method, the nozzle is fixed and the angle of the nozzle cannot be adjusted to adjust the angle of the water spray, which may cause the workpiece to be subjected to uneven cooling shock during the quenching process, thereby increasing the risk of defects such as quenching cracks, deformation, and substandard hardness.

[0003] For example, the utility model with announcement number CN220665377U discloses a spray quenching hardening equipment for metal parts. In the technical solution of this patent, a water tank is fixedly connected in the middle of one side of the quenching box, a water pump is fixedly connected to one side of the bottom end of the water tank, a water pipe is fixedly connected to the input end of the water pump, and the water pipe extends into the interior of the quenching box and is connected to a nozzle to quench the workpiece. However, in this method, the nozzle is fixed and the angle of the nozzle cannot be adjusted to adjust the angle of the water spray. Different metal workpieces have different geometric shapes and quenching requirements. The fixed nozzle angle may cause the water mist or cooling medium to fail to evenly cover all important areas of the workpiece. Especially for complex three-dimensional workpieces, it may cause local insufficient cooling or excessive cooling, affecting the hardness distribution and overall performance of the workpiece.

[0004] In view of this, the utility model aims to provide a metal quenching equipment to address the deficiencies of the prior art. The utility model can not only extract and discharge exhaust gas from the box through the provided fan, which is beneficial to maintaining the purity and surface quality of the metal material, but also adjust the water spray angle of the nozzle by providing an adjustment mechanism, so as to more accurately control the range and intensity of water mist covering the workpiece surface, thereby effectively adjusting the cooling speed and ensuring that the ideal metallographic structure and hardness distribution are achieved.

[0011] As a further improvement of the utility model, a support base is provided at the bottom of the quenching box, and anti-slip stripes are provided on the bottom outer wall of the support base.
