Description
Technical field
The utility model is related to a kind of cutoff device of cold headers, especially a kind of quick blank dress of the swing type of cold headers
It sets.
Background technology
By applicant's earlier application, the Chinese utility model patent document of bulletin of Patent No. 201220418380.7
It is middle to have recorded a kind of cutting mechanism of cold headers.The cutting mechanism is cut by the rotation band moving surface slider-actuated of power crankshaft
Knife assembly works.
There are following technological deficiencies for the cutting mechanism of above structure：
1, on the curved surface sliding block curvature linear gradient curved surface, one of cutting assemblies shearing of curved surface driving
Period is relatively long, and shear velocity is relatively slow, and the planarization of workpiece shear surface is relatively poor；
2, the period of a straight reciprocating motion of the cutting mechanism mean camber sliding block is relatively long, therefore the cutter
The structural compactness of structure is poor.
Utility model content
One kind is provided purpose of the utility model is to solve above-mentioned the deficiencies in the prior art can promote blank speed
The quick cutoff device of swing type of the cold headers of degree.
To achieve the goals above, the quick cutoff device of swing type of a kind of cold headers designed by the utility model,
Including：
The shearing pedestal of one cold headers is set on the shearing pedestal there are one guide through hole and an installation through-hole, and two
The axially bored line of person intersects vertically；
One runs through above-mentioned guide through hole, and the pull rod to do reciprocating linear motion in guide through hole；
The driving gear of one and cold headers is coaxially fixed, and with the cutting cam of driving gear linkage, the cutting is convex
Outside of the wheel positioned at the side aperture of guide through hole；
One V-shaped structure, and bending part is hinged to the first cutting rocking arm on the shearing pedestal of cold headers；This first is cut
An end and an end of above-mentioned pull rod for disconnected rocking arm is hinged, another end rests on above-mentioned cutting cam；
One V-shaped structure, and bending part is hinged to the second cutting rocking arm on the shearing pedestal of cold headers；This second is cut
Disconnected rocking arm is located at the outside in the other side aperture of above-mentioned guide through hole, an end of the second cutting rocking arm and above-mentioned pull rod
Another end is hinged；
One runs through above-mentioned installation through-hole, and the scissors bar to do reciprocating linear motion in installation through-hole, the scissors bar position
Top in another end that above-mentioned second cuts rocking arm, and be hinged with the end；
And the cutting assemblies of a shearing end for being fixed on above-mentioned scissors bar.
A kind of quick cutoff device of swing type of above-mentioned cold headers is in specific works, and the cutting actuated by cams in structure
First cuts rocking arm rotates around its articulated shaft, and straight-line displacement occurs for synchronous pull rod, and synchronous second, which cuts rocking bar, also cuts with scissors around it
Spindle rotates, and the synchronous cutting assemblies being fixed on scissors bar are completed to cut to being sheared workpiece.It is by cutting cam（Generation
For curved surface sliding block in the prior art）Scissors bar is driven, the shear velocity of scissors bar is relatively fast, and the shearing used time is relatively fewer,
The shear surface for being sheared workpiece is smooth.
A kind of quick cutoff device of swing type for cold headers that the utility model obtains, compare the prior art, has
Shear velocity is fast, and workpiece shear plane planarization is good, structural compactness well some equal row the advantages of.
Description of the drawings
