Abstract
A channel steel cutting-off die comprises an upper die base, a U-shaped support, a moving cutter, rolling cutters, a fixed cutter, a cutter base, a pin shaft, a lower die base and a workpiece, a bolt is used for fixing the U-shaped support above the upper die base, the moving cutter, the rolling cutter and the fixed cutter are made of high quality carbon tool steel, the bolt is used for fixing the moving cutter at the bottom of an opening position of the U-shaped support, the rolling cutters are in a hinged connection with the ends of two sides of the U-shaped support through the pin shaft, the cutter base is fixed on the lower die base, the fixed cutter is fixed on the cutter base, accordingly, an entirety is formed by the moving cutter and the rolling cutters on the two sides, a shearing blade is formed by the entirety and the fixed cutter, and under the action of a press machine, a channel steel workpiece can be cut off by the aid of downwards pressing of the moving cutter and the rolling cutters and the function of the fixed cutter.
Description
Technical field
The present invention relates to a kind of knife edge die, particularly a kind of channel-section steel knife edge die belongs to mould and stamping technology field.
Background technology
In many production occasion and fields; Need block by certain length channel-section steel, at present, because the cross section of channel-section steel is comparatively complicated; The common use of blocking of channel-section steel is accomplished cutting work with equipment such as abrasive wheel cutting machine, flame cutting machine and sawing machines; All there is cutting problem separately in above-mentioned several kinds of cutting structures, and for example: the flying dust of abrasive wheel cutting machine is big, the flame cutting machine flue gas is prone to pollute limitation that the sawing machine price is high or the like greatly to environment; The existence of the problems referred to above brings passive in the work easily.
Summary of the invention:
The objective of the invention is to: a kind of channel-section steel knife edge die is provided, and therefore its cheap not pollution simple in structure, can bring the facility in the work.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of channel-section steel knife edge die; It is made up of upper bolster, U type support, moving cutting knife, rolling cutter, fixed cutting tool, Cutter apron, bearing pin, die shoe, workpiece; With bolt with U type support be fixed on upper bolster above; Moving cutting knife, rolling cutter, fixed cutting tool adopt the quality carbon tool steel manufacturing to form, and will move cutting knife with bolt and be fixed on the bottom that U type support is opened grade position, and rolling cutter is hinged on the end of the both sides of U type support through bearing pin; Cutter apron is fixed on the die shoe, and fixed cutting tool is fixed on the Cutter apron; So, move the whole and fixed cutting tool formation shear blade of rolling cut cutter of cutting knife and both sides; Like this, the action that moving cutting knife and rolling cut cutter press down under the effect of forcing press and the effect of fixed cutting tool can cut the channel-section steel workpiece.
Beneficial effect: the present invention is owing to use and with the cold-stamped way channel-section steel to be carried out MATERIAL CUTTING, and cold-punching mould just can accomplish among a stroke the blocking of channel-section steel, and therefore, its is simple in structure cheap less than pollution and result of use is good.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Fig. 1 is a front view of the present invention.
Fig. 2 is the cross section left view of Fig. 1.
Shown in the figure: 1, upper bolster; 2, U type support; 3, moving cutting knife; 4, rolling cutter; 5, fixed cutting tool; 6, Cutter apron; 7, bearing pin; 8, die shoe; 9, workpiece.
The specific embodiment
It is made up of upper bolster 1, U type support 2, moving cutting knife 3, rolling cutter 4, fixed cutting tool 5, Cutter apron 6, bearing pin 7, die shoe 8, workpiece 9; With bolt with U type support 2 be fixed on upper bolster 1 above; Moving cutting knife 3, rolling cutter 4, fixed cutting tool 5 adopt the quality carbon tool steel manufacturing to form; To move cutting knife 3 with bolt and be fixed on the bottom that U type support 2 is opened grade position; Rolling cutter 4 is hinged on the end of the both sides of U type support 2 through bearing pin 7, and Cutter apron 6 is fixed on the die shoe 8, and fixed cutting tool 5 is fixed on the Cutter apron 6; So, move the integral body and the fixed cutting tool 5 formation shear blade of rolling cut cutter 4 formation of cutting knife 3 and both sides; Like this, the action that moving cutting knife 3 and rolling cut cutter 4 press down under the effect of forcing press and the effect of fixed cutting tool 5 can be blocked channel-section steel workpiece 9.
