Embodiment Construction
[0014] The present invention is further set forth below through the accompanying drawings of the description;
[0015] according to figure 1 , figure 2 , image 3 As shown, the steel is cut by a CNC horizontal sawing machine and then heated in a heating furnace to about 1200°C before being released from the furnace. The scale is removed by a high-pressure water gun and directly put into the forming mold. The wheel groove and shaft are removed by a 10,000-ton forging press within 30 seconds. The structures other than the holes are all formed, roughed, returned to the furnace for heating, and put into the mold; after the mold is formed, the roller groove of the rolling mill is used to complete the process that requires rough machining in the traditional process within 120 seconds, that is, the wheel groove of the crane is formed and retained for 3 -5mm machining allowance for finishing after quenching and tempering; after punching the shaft hole, all crane wheels are formed, ...

The invention provides a once forming fabrication technology of a die forging crane wheel, which comprises the steps of heating steel, oxidizing, entering a forming die, conducting blanking on the steel with a numerical-control horizontal sawing machine, allowing the steel to enter a heating furnace, heating the steel to be about 1200 DEG C, allowing the steel to be discharged from the furnace, removing oxide skins with a high-pressure water gun, entering the forming die directly, fabricating and forming all structures except wheel grooves and a shaft hole within 30 seconds with a megaton forging machine, accomplishing upsetting, returning to the furnace for heating, and entering the die. The technology adopts the technical scheme that with the adoption of the advanced technology, the production procedures can be decreased, the production cost can be lowered greatly, and the production efficiency can be improved greatly.
Description
technical field [0001] The invention relates to a crane wheel production technology. In particular, it can greatly reduce production costs and improve production efficiency. Background technique [0002] At present, the production process of domestic die forging crane wheels requires secondary heating and the wheel groove cannot be formed during the forging process. The production process is mostly blanking, heating, thickening, reheating, removal of scale, forming into the mold, Punching, heat treatment, trimming, storage of blanks, rough machining, quenching and tempering, finishing, storage of finished products, and some even require three times of heating. This will inevitably cause high production costs and low efficiency, which are not conducive to manufacturers and users competing in today's fierce market competition. Contents of the invention [0003] In order to overcome the shortcomings of high production cost and low efficiency caused by reheating and rough ma...
