Embodiment Construction
[0015] The present invention will be described in further detail below by means of specific embodiments:
[0016] The reference signs in the drawings of the description include:
[0017] Bracket 11, workbench 12, water storage tank 13, pressure plate 14, first nozzle 15, baffle plate 16, through hole 17, first rotating shaft 18, water-absorbing block 19, second rotating shaft 20, dial bar 21, third rotating shaft 22, Reservoir 23, suction pipe 24, refrigeration pump 25, second spray nozzle 26, curved plate 27, guard plate 28, exhaust fan 29.
[0018] Such as figure 1 The shown gear forging cooling device includes a bracket 11 and a workbench 12. The bracket 11 is fixedly installed on the right end of the workbench 12. A hollow pressure plate 14 is arranged on the bracket 11. The pressure plate 14 is inclined in the left side and the right side is high. The hollow layer of 14 is connected to the water storage tank 13, and 50 first nozzles 15 are evenly arranged on the upper s...

The invention belongs to the technical field of forging equipment and particularly relates to a cooling device for gear forging machining. A bracket is fixedly mounted on a workbench. A hollow layer in a pressing plate on the bracket is connected with a water storage tank. Multiple first spray heads are arranged on the upper surface of the inclined pressing plate and are the spray heads made of metal. A one-way water outlet hole is formed between each first spray head and the pressing plate. Hollow protective plates are fixedly mounted on the two sides of the pressing plate and communicate with the pressing plate. Multiple second spray heads are arranged on the inner side of each protective plate. An inductor is arranged on each second spray head. An arc-shaped plate is arranged below the pressing plate. A first rotary shaft is arranged on the arc-shaped plate in a penetrating manner. A through hole is formed in the arc-shaped plate. A baffle inclining towards the arc-shaped plate is arranged on the position, in contact with a rack, of the lower end of the pressing plate. The cooling device solves the problems that the cooling speeds of a gear hub and the rim of a gear are different, workpiece residual stress-strain elimination speeds of the gear hub and the rim of the gear are different, consequently the gear deforms easily, and the dimensional precision of the gear is influenced.
Description
technical field [0001] The invention belongs to the technical field of forging equipment, and in particular relates to a cooling device for gear forging processing with the same cooling speed of gear tooth grooves and gear hubs. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. It appeared very early in transmission applications. Because of its smooth and continuous transmission, it is widely used in various fields of machinery; gears are deceleration One of the essential components in the box, the quality of the gear determines the stability of the transmission and the accuracy of the reduction ratio. Now more precise mechanical gear components are generally produced by forging. The operation process is to use a forging machine for forging, place the gear workpiece in the forging die, and use the forging hammer of the forging machine to forge. In the forging process, the gear workpie...
