Description
Technical field
The invention belongs to the nearly clear height of low energy consumption and imitate the precision molding technology field.Relate to a kind of blanking machine, particularly a kind of Pneumatic radial impact blanking machine, this blanking machine adopts the Pneumatic immpacting principle, realizes that the fatigue crack of bar under the cycle radial loaded circumferentially produces, expands until fracture, finally finishes precise blanking.
Background technology
The blanking of metal bar material extensively is present in the procedure for preparation of cold extrusion, die forging, metal bracelet pin, rolling bearing roller, pin standard component and axle class part, and in these blanking operations, blanking enormous amount, baiting methods such as at present traditional shearing, sawing, high energy cutting exist to some extent that stock utilization is low, blanking pressure is big, energy consumption is high, production efficiency is low and problem such as blanking cross section quality difference.
Summary of the invention
The objective of the invention is to, a kind of Pneumatic immpacting high efficiency precise blanking machine is provided.This blanking machine can impel crackle by the radially circumference expansion of bar surface, therefore can obtain good cross section quality, and have advantages such as the range of work is wide, efficient is high, quality is good.
In order to realize above-mentioned task, the present invention takes following technical solution:
A kind of Pneumatic radial impact blanking machine comprises base, is provided with bar fixture and stand on base, it is characterized in that:
Described bar fixture mainly is made of blanking sleeve, bar fixed cover, elasticity cushion cover and bar fixed support, the bar fixed cover is connected with the bar fixed support by interference fits, and an end of blanking sleeve forms with the bar fixed support by the elasticity cushion cover and cooperates;
Described stand upper edge bar radially evenly is furnished with a blow cylinder, has piston on the blow cylinder, and the blanking mould is installed on the piston, and the working profile curve of this blanking mould adopts cycloid;
In the blanking process, bar one end is installed in the endoporus of bar fixed cover, an other end inserts in the blanking sleeve, blow cylinder is done the radial impact motion by the ordered pair bar under control system control, under the drive of the piston of blow cylinder, drive the blanking mould and constantly radially give the bar imposed load, thereby finish radially Pneumatic immpacting blanking process of bar along bar.
The radial impact stroke of blanking mould can be regulated to adapt to the technological requirement of various different-diameter bars; Blow cylinder can provide the shock loading of different frequency and pressure according to technological requirement, and presses specified order work according to technological requirement.
Pneumatic radial impact high efficiency precise blanking machine of the present invention, when carrying out blanking, the bar centering is static, in the plane of vertical bar axis, evenly 7 blow cylinders arranging are in the compressed air pressure regulating system, magnetic valve exchange system and intelligent control system control is efficiently given the bar radial loaded successively by technological requirement down, each like this have only a blanking mould in running order in, guaranteed that bar only has load in one direction, can not interfere between each blanking mould.Rationally the blow cylinder that distributes can be realized circumferential uniformly tired loading of bar, thereby impels the stable expansion of micro-crack, guarantees cross section quality.Have frequency height, frequency adjustable, advantages such as impulsive force is adjustable, economical and practical convenience.
