The reinforcing steel shearing mechanism also comprises an integral type fixed knife holder that is arranged on a rack; the other side of the fixed shaft of the shearing arm is arranged in a hole of the integral type fixed knife holder, and a fixed knife is also arranged on the integral type fixed knife holder; the end surface of the fixed knife is arranged on the shearing surface of the moving knife; and holes through which reinforcing steel can penetrate are arranged on the integral type fixed knife holder and the fixed knife. The reinforcing steel shearing mechanism has the beneficial effects that with the adoption of the integral type fixed knife holder structure, the structure of the mechanism is greatly simplified, the knife changing is convenient, the processing is simple, the overall strength is high, and the mechanism is suitable for shearing the reinforcing steel with major diameters.
Description
Technical field
The utility model relates to the bar cutting mechanism on the reinforcing bar automatic processing devices such as hoop bender, aligning cutting-off device, particularly be bar cutting mechanism with unitary fixed tool rest structure.
Background technology
Along with the economic construction fast development, process stirrup equipment automatically---steel-bar automatic hoop bender has obtained using widely.The prior art steel-bar automatic hoop bender comprises: feed mechanism, straightening mechanism, bending mechanism and cutting mechanism.Above-mentioned cutting mechanism is the key mechanism of steel-bar automatic hoop bender, and this mechanism is used for a reinforcing bar and cuts off at preseting length.
The cutting mechanism of the steel-bar automatic hoop bender of prior art generally is that eccentric shaft drivening rod drive shear arm is finished shearing, but the fixedly tool rest of prior art is made up of two parts part, one is used for installing the shear arm fixed axis, one is used for installing and fixing cutter, two connect complexity, and intensity is also bad.Often there are loosening, rapid wear, tool changing trouble, defective such as undercapacity, installation and maintenance trouble when particularly shearing the major diameter reinforcing bar during shearing.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, a kind of cutting mechanism simple in structure is provided, be characterized in having adopted unitary fixed tool rest structure, make shear arm fixed axis and dead knife all be installed on the unitary fixed tool rest, install simple, tool changing is convenient, and processing is simple, the integral intensity height.
The technical scheme that solves the problems of the technologies described above is: a kind of bar cutting mechanism with unitary fixed tool rest structure, and described bar cutting mechanism comprises: Motorized drive unit; One end of eccentric shaft connects Motorized drive unit output, eccentric shaft other end articulated linkage one end, an end of the hinged shear arm of the connecting rod other end; Shear arm is hinged on the end of shear arm fixed axis one side, the shear arm other end is equipped with movable blade, described bar cutting mechanism also comprises the unitary fixed tool rest, described unitary fixed tool rest is contained on the frame, the opposite side of shear arm fixed axis is housed in unitary fixed tool rest hole, dead knife also is housed on the unitary fixed tool rest; The end face of described dead knife is positioned on the shear surface of movable blade; The hole that on unitary fixed tool rest and dead knife, has reinforcing bar to run through.
The beneficial effects of the utility model are: the utility model has adopted unitary fixed tool rest structure, and structure is simplified greatly, and tool changing is convenient, and processing is simple, and the integral intensity height is suitable for shearing the major diameter reinforcing bar.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is that master of the present utility model looks schematic diagram; Fig. 2 is Fig. 1 left side partial cutaway schematic diagram; Fig. 3 is the local enlarged diagram at the shearing position among Fig. 1; Fig. 4 is the vertical view cutaway drawing of Fig. 3.
As shown in the figure, the utility model provides a kind of bar cutting mechanism with unitary fixed tool rest structure, and described bar cutting mechanism comprises: Motorized drive unit (figure does not show); One end of eccentric shaft 8 connects Motorized drive unit output, eccentric shaft 8 other end articulated linkage 2 one ends, an end of the hinged shear arm 3 of connecting rod 2 other ends; Shear arm 3 is hinged on the end of shear arm fixed axis 10 1 sides, and shear arm 3 other ends are equipped with movable blade 6.
Described bar cutting mechanism also comprises unitary fixed tool rest 4, and described unitary fixed tool rest 4 is contained on the frame 1, and the opposite side of shear arm fixed axis 10 is housed in unitary fixed tool rest 4 holes, and dead knife 5 also is housed on the unitary fixed tool rest 4.
The end face of described dead knife 5 is positioned on the shear surface of movable blade 6; The hole that on unitary fixed tool rest 4 and dead knife 5, has reinforcing bar 7 to run through.
As Fig. 2, shown in Figure 4, on shear arm fixed axis 10 opposite side end faces, shear arm gland 9 is housed, described shear arm gland 9 usefulness securing members are fixed on shear arm fixed axis 10 end faces, and shear arm gland 9 covers shear arm fixed axis 10 in unitary fixed tool rest 4 holes.Shear arm gland 9 and securing member are fixed in unitary fixed tool rest 4 holes shear arm fixed axis 10.
Below the course of work of the present utility model is described:
Motorized drive unit drives eccentric shaft 8 and rotates, eccentric shaft 8 drivening rods 2 move up and down, and then drive shear arm 3 one ends move up and down, shear arm 3 with shear arm fixed axis 10 as spot wobble, the movable blade 6 formation levers of shear arm 3 other ends are swung thereupon, movable blade 6 and dead knife 5 relative motions that are installed on the unitary fixed tool rest 4 are cut off the reinforcing bar 7 that passes in the dead knife 5.
