Description

Processing auxiliary equipment for steel ball production Technical Field The invention relates to the field of steel ball production, in particular to processing auxiliary equipment for steel ball production. Background In the fields of bearings, grinding, transmission machinery and the like, the steel ball is used as a core part, and the hardness, the wear resistance and the dimensional stability of the steel ball directly determine the service life and the operation precision of a terminal product. In order to obtain mechanical properties meeting the use requirements of the steel ball, a heat treatment quenching process is a key link in the production process of the steel ball, and the process realizes the phase change of the internal structure of the steel ball by accurately controlling the temperature change so as to further improve the core performance of the steel ball. The standard quenching process flow of the steel ball is clear, the steel ball is heated to an austenitizing temperature range, so that the internal structure of the steel ball is completely converted into a uniform austenite structure, a foundation is laid for subsequent phase transformation, the steel ball is cooled to a specific quenching temperature, and then the steel ball is put into a corresponding quenching tank to be cooled at a preset cooling rate, so that the austenite structure is converted into a martensite structure, and finally the hardness and the wear resistance of the steel ball are improved. The method is characterized in that the accurate control of austenitizing temperature and quenching temperature and the stability of the cooling process are core elements for guaranteeing the quenching quality of the steel balls. In the actual production process, the steel balls produced in the same batch inevitably have the problem of inconsistent weight due to the influence of factors such as batch difference of raw materials, fluctuation of forging precision, uneven surface machining allowance and the like. The weight difference of the steel balls can directly cause mass effect in the heating treatment process, under the same heating, cooling and cooling conditions, the heat conduction efficiency and the temperature response rate of the steel balls with different weights have obvious differences, namely, the heat dissipation in the heavier steel balls is slower, if the heavier steel balls and the lighter steel balls are mixed into the same quenching tank for quenching, the defects of insufficient quenching, insufficient core hardness and the like are likely to occur, and the qualification rate of steel ball finished products is seriously affected due to the problems of cracks, deformation and the like caused by the too fast cooling speed of the lighter steel balls. Therefore, in order to ensure quenching quality, steel balls with different weights need to be screened and separated before quenching, and are put into a quenching tank with corresponding technological parameters for targeted treatment. At present, the screening of the weight of steel balls in industry mostly adopts a sorting mode after quenching, namely, after all steel balls are quenched, tempered and cooled to room temperature, the weight of the steel balls is classified and screened by weighing equipment, and then the unqualified or weight deviation exceeding steel balls are reworked. However, the post screening mode has the technical defects that on one hand, unqualified steel balls after quenching are subjected to full-flow heat treatment such as heating, quenching, tempering and the like again, so that the energy consumption and the production time are greatly increased, coarse grains of steel ball tissues, performance attenuation and even irreversible deformation defects are generated due to the secondary heat treatment, the added value of products is reduced, and on the other hand, the defects of the steel balls which are partially failed in quenching due to weight difference cannot be completely repaired through reworking during post screening, and the steel balls can only be treated as waste and defective products, so that the waste of raw materials and production cost is caused. In summary, in the current steel ball production process, there is a need for a processing auxiliary device for steel ball production, which can adapt to high temperature conditions and synchronously complete weight screening in the cooling process after steel ball heating. Disclosure of Invention The technical scheme is that the processing auxiliary equipment for steel ball production comprises a cooling shell, wherein a feeding adapter is arranged at the top of the cooling shell, the bottom of the cooling shell is communicated with a discharging pipe, one side, far away from the cooling shell, of the discharging pipe is communicated with a screening box, the screening box is communicated with a first outlet and a second outlet, symmetrical lifting blocks are arranged on a supp
