Abstract
The invention discloses a multi-face combination fixed cutter of an automatic steel bar hoop bending machine. The multi-face combination fixed cutter comprises a fixed cutter base, a through hole is formed in the fixed cutter base, and a multi-face combination fixed cutter head is arranged on the fixed cutter base. The multi-face combination fixed cutter head comprises a multi-face fixed cutter head body and a clamping block, the multi-face fixed cutter head body is provided with a steel bar through hole, and the steel bar through hole is communicated with the through hole of the fixed cutter base. The left side face and the right side face of the multi-face fixed cutter head body are the same in structure to be in mirror symmetry and are respectively provided with a threaded hole. One side of the clamping block is matched to be arranged on one of the side faces on the left side and the right side of the multi-face fixed cutter head body, and the clamping block and the multi-face fixed cutter head body are fixed together through screws. The multi-face combination fixed cutter of the automatic steel bar hoop bending machine has the advantages that after one face of the multi-face fixed cutter head body is abraded, the screws are dismounted, the fixed cutter is rotated to the symmetrical face, and another non-abraded cutting edge is mounted again to shear steel bars; multi-face use of one multi-face fixed cutter head body is achieved, the service life is prolonged by multiple times, the using cost of easily-damaged parts is lowered, and replacing is convenient.

Embodiment
Embodiments of the invention are described in further detail below in conjunction with the accompanying drawings.
Fig. 7 is the multiaspect combination fixing cutter structural representation of the present invention；Fig. 8 is C-C sectional views in Fig. 7；Fig. 9 is Fig. 7 left side view；Figure 10 is the fixed cutter head front view of multiaspect in Fig. 7；Figure 11 is Figure 10 left side view；Figure 12 is B-B sectional views in Figure 10.
It should be noted that the part in the present invention is identical with part of the prior art, using identical sequence number, the structure of same parts is in this description will be omitted.
As shown in Fig. 7-Figure 12, the present invention provides a kind of multiaspect of steel-bar automatic hoop bender combination fixing cutter, including：One fixed tool rest 1, has the through hole 1a that reinforcing bar 5 runs through on fixed tool rest 1.Fixed tool rest 1 uses the structure of prior art, to fixing the structure of tool rest 1 in this description will be omitted.
The fixed cutter head 20 of multiaspect combination is fitted with the fixed tool rest 1, the structure of the fixed cutter head 20 of multiaspect combination includes：Multiaspect fixed cutter head 20c, fixture block 3.
There are the reinforced steel bar perforation 20a of insertion, reinforced steel bar perforation 20a to be connected with the through hole 1a of fixed tool rest 1 on the fixed cutter head 20c of the multiaspect；Multiaspect fixes the identical specular of cutter head 20c left and right sides structures and has screwed hole respectively；One side-anastomosis of the fixture block 3 is in multiaspect with fixing on one of side of the cutter head 20c left and right sides, and fixture block 3 is fixed as one by screw 4 with multiaspect with fixed cutter head 20c, and another of fixture block 3 has the boss 3a being stuck on fixed tool rest 1 sideways.
The screwed hole of the fixed cutter head 20c left and right sides of the multiaspect has two respectively.
The bottom of fixed tool rest 1 and the fixed side end of tool rest 1 one have U-type groove and dovetail groove respectively, and the dovetail groove is vertical with U-type groove；Multiaspect is dovetail face 20b with fixed cutter head 20c two sides up and down, and dovetail face 20b is fitted in the dovetail groove of fixed tool rest 1.
There is the reinforced steel bar perforation 20a of insertion two sides before and after the fixed cutter head 20c of the multiaspect；The boss 3a of another side of the fixture block 3 is stuck in the U-type groove bottom surface of fixed tool rest 1.
The dovetail channel opening of the side end of fixed tool rest 1 one is less than the dovetail channel opening of the fixed bottom surface of tool rest 1.
More specifically, because multiaspect of the present invention fixes the identical specular of cutter head 20c left and right sides structures and has screwed hole respectively, after the fixed cutter head 20c of multiaspect reinforced steel bar perforation 20a lower insides are worn and torn by shearing force, as long as unclamping screw 4, conversion multiaspect reinstalls fixture block 3 with fixed cutter head 20c directions, you can exchanges reinforced steel bar perforation 20a position, reuses the another side not worn and torn, equivalent to a new cutter head is changed, reach that same fixes the effect that cutter head multiaspect is used.
