After finishing short bar material shaping, ejecting steel ball blank is ejecting through the ejecting steel ball blank of the lower liftout device that sets up in electronic screw press 9 lower part, later by six axis robot 8 with steel ball blank propelling movement to raceway 11 on, after accomplishing the propelling movement, carry out spray cooling through the cooling device who sets up on six axis robot 8 to mould 10, guarantee this mould 10 repeatedly usable, improve this major diameter wear-resisting steel ball full automated production system's practicality. The roller path 11 is arranged between the electric screw press 9 and the rounding machine 12 and is used for conveying the steel ball blank from the die 10 to the inside of the rounding machine 12. The raceway 11 is formed by welding steel plates, and meanwhile, a steel ball blank conveying and detecting unit is arranged, so that the number of steel ball blanks hit by the electric screw press 9 is determined to be the same as the ball output number of the rounding machine 12, and the safety of the full-automatic large-diameter wear-resistant steel ball production system is improved. The rounding machine 12 is arranged at the rear end of the raceway 11 and used for rounding the steel ball blank conveyed by the raceway 11, the rounding machine 12 is integrally of a frame type structure, and the steel ball blank is rolled into a complete circle by adopting a ball-imitating double-roller die and rotating by a high-power motor. The speed of the whole circle is controlled by the frequency converter, the surface temperature of the die is reduced by spraying water, damage to equipment is avoided, and the safety of the full-automatic production system of the large-diameter wear-resistant steel ball is further improved.
The embodiment of the invention provides a full-automatic production system for large-diameter wear-resistant steel balls, which has the working principle and implementation steps as follows:
step 1: the batched long bars pass through a discharging device, enter a natural gas heating furnace 1 at regular time, are heated to the temperature 1180 ℃ required by the forging process, and then reach a discharging port. And then, the heated long bar is taken out of the natural gas heating furnace through the roller way 2. In the process of conveying the long bar material on the roller way 2, the long bar material passes through the descaling machine 3 to remove thick scale on the surface of the long bar material caused by long-time heating oxidation.
Step 2: the long bar stock is quickly pushed into an inlet of the bar shearing machine 5 through the material pushing device 4, and after the bar shearing machine 5 shears once, the long cylinder of the material pushing device 4 acts once until the whole long bar stock is sheared completely. Each cut short bar material is transported by a conveyor belt 6 and slides to a sequencing device 7, the first short bar material of the sequencing device 7 slides to a material cup, the material cup is turned by 90 degrees to erect the short bar material, and a six-axis robot 8 is waited for taking the material. And sequentially queuing the subsequent short bars in the slideway. A six-axis robot 8 feeds short rods into a mould 10.
And step 3: and the electric screw press 9 strikes the sliding block downwards according to a set press value to finish the forming of the steel ball blank. And in the upward moving process of the sliding block, the lower ejection device ejects the steel ball blank. The six-axis robot 8 pushes the steel ball blank out to the raceway 11 and completes the spray cooling of the mold 10. The steel ball rolls into the rounding machine 12 through the raceway to be shaped into a complete wear-resistant steel ball.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
