Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a precise temperature control heat treatment device for a lower connecting plate forging die. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to the metal billet to cause it to deform plastically, its mechanical properties can be changed. Forgings can be divided into cold forging and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. The lower connecting plate is one of the most important parts of all parts of motorcycles and electric bicycles. Since its steering column bears most of the force of the front wheel during the operation of the vehicle, its quality directly affects driving safety. If there is quality problem, The consequences of accidents will be disastrous, so the lower connecting plate assembly is regarded as a Class A part that is equally important as the front wheel. The steering column of the lower connecting plate is the most difficult part to process, and the process route is relatively long. The quality of the process directly affects the quality of the component. During forging, when the hot forging is completed, the lower connecting plate needs to be placed in water for heat treatment and cooling before the next processing can be carried out. If the surface of the lower connecting plate is not cooled evenly, the processing will cause cracks. At the same time, due to the large local temperature difference of the forging, the difference in the local mechanical properties of the forging becomes larger, which in turn affects the performance of the forging.

[0003] When the existing heat treatment device cools down the lower link plate forging, since the lower link plate forging is fixed when entering the coolant, its surface cooling is uneven, small cracks will be generated, affecting subsequent processing, and multiple lower link plate forgings cannot be heat treated at the same time, reducing the overall heat treatment efficiency.
