Description
Technical field
The present invention relates to a kind of parts of multistage cold former, particularly a kind of Multistage cold former idler wheel type back through ejector rod device.
Background technology
Multistage cold former adopts header system that bar automatically upsetting is made various hex nut.In multistage cold former work, bar is through roller driving charging, successively feeding, blank, pressure ball, pressure angle, punching, the advantages such as a few procedure one machine completes, and cold-heading station, by horizontally, has accurate positioning, stable operation, easy to maintenance.
In the rear logical pin-lift arrangement of at home and abroad numerous multistage cold former, all adopt top bolt, the application of this type of top structure is with a long history, is widely used especially in machinery industry.The defect of this class formation is: (1) because of top bolt and rear running-through bar between be sliding friction, cause rear logical push rod and rear running-through bar easy to wear, often to debug, regularly replace top bolt; (2) as shown in Figure 1, when cold headers run, rear logical rocking arm 10 does reciprocally swinging centered by A, and making to come directly towards between bolt 13 and rear running-through bar 11 during top lifting has larger angle, cause rear running-through bar 11 to have larger radial force, make rear running-through bar 11 easily broken, change trouble, cost is high.(3) coming directly towards bolt 13 with rear running-through bar 11 is point cantact, and longevity of service easily makes rear running-through bar 11 end face produce depression, and then makes rear running-through bar 11 generation distortion extremely swollen with rear logical swivel nut 12.
Summary of the invention
The object of the invention is to provide a kind of long service life, Multistage cold former idler wheel type back through ejector rod device rational in infrastructure to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, Multistage cold former idler wheel type back through ejector rod device designed by the present invention, comprise rear logical tip-lever support, logical lifter guide after an end of rear logical tip-lever support is socketed with, the sidewall of described rear logical lifter guide one end is provided with the first through hole, described rear logical tip-lever support is provided with the first tapped through hole, above-mentioned first through hole and the first tapped through hole are coaxial, and both maximum inner diameters are identical, logical push rod adjusting bolt after being jointly provided with in the first through hole and the first tapped through hole, rear logical push rod adjusting bolt coordinates with the first tapped through hole, and the bolt head of rear logical push rod adjusting bolt is positioned at outside rear logical lifter guide, the bolt shank of described rear logical push rod adjusting bolt is provided with annular groove, described annular groove is positioned at the first through hole, the roof of described rear logical lifter guide is provided with the second tapped through hole and waist-shaped hole, described second tapped through hole and the first through hole run through mutually, lifter guide caging bolt is connected with in the second tapped through hole, the top of described lifter guide caging bolt extends in annular groove, and be interference fit with the inwall of annular groove, the end face of rear logical tip-lever support is connected with guide rail lock-screw, described guide rail lock-screw runs through waist-shaped hole, and the maximum gauge of the screw head of guide rail lock-screw is greater than the internal diameter of waist-shaped hole, in the opening's edge of the rear logical lifter guide other end detachable be fixed with after logical push rod roller mount, described rear logical push rod roller mount and rear logical lifter guide run through, logical push rod roller shaft after being connected with between the two side of rear logical push rod roller mount, logical push rod roller after above-mentioned rear logical push rod roller shaft is socketed with, and rear logical push rod roller portion exposes rear logical push rod roller mount.
In Multistage cold former idler wheel type back through ejector rod device provided by the present invention, idler wheel mechanism is utilized to replace common push rod bolt arrangement, because force of rolling friction is far smaller than force of sliding friction, reduce the wearing and tearing to rear running-through bar, and utilize the radial force of rolling principle minimizing to rear running-through bar, to avoid the fracture of rear running-through bar, reduce the maintenance cost in later stage, because roller and rear running-through bar are linear contact lay, avoid rear running-through bar end face and produce depression, and then make rear running-through bar produce distortion may reducing extremely swollen with rear logical swivel nut, reduce the incidence of fault.
In order to promote the planing stability of rear logical tip-lever support in rear logical lifter guide, thus lifting job stability, the two side of rear logical lifter guide described in the present invention is arranged with and slides groove, the two side of described rear logical tip-lever support is equipped with and the above-mentioned directive slide track sliding groove fit.
Conveniently lead to the property easy to connect of tip-lever support and rocking arm afterwards, after described in the present invention, the bottom of logical tip-lever support is provided with rocking arm connecting hole.
The Multistage cold former idler wheel type back through ejector rod device that the present invention obtains, it has advantage: 1, wearability, and linear contact lay when rear logical push rod roller utilizes roller, reduces the wearing and tearing to rear running-through bar; 2, the life-span is long, utilizes the radial force of rolling principle minimizing to rear running-through bar, prevents fracture.
