Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 and Figure 4, a kind of aluminium block processing crankshaft group of automatic punching machine, including crankshaft body 1, connecting shaft 2
With cooling mechanism 3, the both ends of the crankshaft body 1 are respectively connected with connecting shaft 2, shown, are arranged with heat dissipation in the connecting shaft 2
Mechanism 3, the cooling mechanism 3 include disk 301 and flabellum 302, and the flabellum 302 is provided with several and is evenly distributed on circle
The periphery of disk 301.
Main rotary gadget of the crankshaft as automatic punching machine after loading onto connecting rod, can accept the movement (reciprocal) up and down of connecting rod
Become to recycle (rotation) movement.During crank rotation, the friction between connecting rod and crankshaft can generate certain heat, such as
The heat dissipation of fruit crankshaft is bad, will result in abrasion, and the formed punch vibration that abrasion will result in punching machine influences punching press effect, the utility model
