Embodiment Construction

[0024] The structure of the high-efficiency precision blanking machine for asymmetric radial forging punching of the present invention is shown in FIG. 1 . The blanking system is mainly composed of the transmission system part, the radial forging blanking part, the stroke fine-tuning part, the bar fixing bracket part and other main components. The above four parts are described in detail below.

[0025] The transmission mechanism of the blanking machine of this invention is mainly composed of a main motor 1, a driving pulley 2, a transmission belt 3, a driven pulley 4, a transmission spindle 5, a lock nut 6, a connecting key 7, an adjustment sleeve 8 and a spindle fixing sleeve. 9 and other components.

[0026] The main motor 1 drives the driving pulley 2 keyed to the motor transmission shaft to rotate, and the driven pulley 4 is driven by the transmission belt 3 to rotate, and the transmission ratio of the transmission mechanism is 5:1.

[0027] Driven pulley 4 is connected...

Abstract

The invention relates to an asymmetrical radial forging highly efficient precision feeder which comprises at least the drive mechanism, radial forging feeding and stroke micro tuning structure and bar material fixture device, with the radial feeding device using hammer cycloid design, cam using cylinder roller device, without impact and stable movement. The turbine worm stroke adjusting device uses separate turbine gear structure, and be able to improve stroke adjustment structure' kinematic behavior. Through servo generator variable-frequency control function, it can make precise blank with various material and different size.

Description

technical field [0001] The invention belongs to the technical field of low energy consumption, near-net and high-efficiency precision molding. It relates to a blanking machine, especially an asymmetric radial forging high-efficiency precision blanking machine. The blanking machine adopts the principle of radial forging to realize the circumferential generation of fatigue cracks on bars under periodic radial loading, Expand until it breaks, thus completing precision blanking. Background technique [0002] The blanking problem of metal bars widely exists in the material preparation process of cold extrusion, die forging, metal chain pins, rolling bearing rollers, bolts, nuts, pins, and shafts, and in these blanking processes, the following The amount of materials is huge. For example, the chain township in Jinhua, Zhejiang Province produces metal chains with a length of hundreds of millions of meters every year. Beijing Needle Roller Bearing Factory n...
