[0002] Wear-resistant steel balls are core consumables in grinding systems of industries such as mining, mineral processing, cement, and building materials. Their forming quality and production efficiency directly affect the production costs and efficiency of downstream industries. Currently, the industry mostly uses a single-station, single-hammer forming process for forging wear-resistant steel balls, which has the following key defects: 1. Low production efficiency: a single press can only form one steel ball per strike, resulting in a significant capacity bottleneck that cannot meet the needs of large-scale production. 2. Low level of automation, poor matching between loading and unloading, conveying and pressing cycle, manual assistance is required, production continuity is insufficient, and there are also safety hazards.

[0014] A molding method using a steel ball bi-pressure molding machine includes the following steps: Step 1: Feed the round steel bars into a walking beam furnace. The furnace is heated in four zones: Zone 1 at 1000℃, Zone 2 at 1100℃, Zone 3 at 1150℃, Zone 4 at 1180℃, and the soaking zone is heated to 1180℃ on the left and 1200℃ on the right. The total heating time in the furnace is 77 minutes. The exit temperature is controlled at 1050±10℃. Immediately after exiting the furnace, the steel bars are subjected to 12MPa high-pressure water to remove the surface oxide scale. Step 2: The processed round steel bars are then conveyed to the first V-type roller conveyor. The conveying component sends the round steel bars in the first V-type roller conveyor to the dual-station synchronous feeding component that needs to be fed. The round steel bars move in the dual-station synchronous feeding component at 200mm / s. The dual-station synchronous feeding component cuts the round steel bars into segments in a quantitative manner. Step 3: The dual-station synchronous feeding component guides the material segments to the dual-station picking component. The dual-station picking component clamps the material segments at the discharge ends of the two dual-station synchronous feeding components and sends them into the dual-station synchronous forging component. Step 4: The dual-station synchronous forging forming assembly clamps and straightens the material segment, and then forms a steel ball according to the preset pressure machine impact energy of 220kJ, slide stroke of 540mm, impact beat of 3s / hammer, downward speed of 250mm / s, and holding time of 0.2s. Step 5: Push the formed steel balls into the guide assembly, which will then transport the formed steel balls one by one into the steel ball rolling machine for rounding.

[0015] Compared with the prior art, the advantages of this invention are as follows: This invention feeds round steel bars into a walking-bottom type natural gas heating furnace, heating them to a forging temperature range of 1050±10℃. The oxide scale on the surface of the bars is removed by a high-pressure water descaling machine. The treated round steel bars are then conveyed to a first V-shaped roller conveyor. A conveying component transports the round steel bars from the first V-shaped roller conveyor to a dual-station synchronous feeding component that requires feeding. The dual-station synchronous feeding component quantitatively cuts the round steel bars into segments, and then guides the segments to achieve simultaneous feeding through multiple channels. A dual-station material handling component clamps two dual-station... The material segment at the discharge end of the synchronous feeding component is sent to the dual-station synchronous forging and forming component. The dual-station synchronous forging and forming component performs one hammer, two balls, and two pressure forming. The dual-station synchronous forging and forming component then pushes the formed steel balls into the guiding component. The guiding component conveys the formed steel balls one by one into the steel ball rolling machine, realizing simultaneous production at four stations. This greatly improves production efficiency and significantly increases production capacity. At the same time, it realizes large-scale continuous production with centralized material supply, parallel forging, and unified material discharge, achieving unmanned continuous production throughout the entire process. The production cycle is stable and controllable, and the labor cost is reduced by more than 70% compared with the traditional process. Attached Figure Description
