Abstract

The utility model relates to a combined cutting knife of a bending hoop machine, which comprises a conducting wire tube and a knife edge, wherein a conducting wire hole is arranged between end surfaces of both sides of the conducting wire tube, a through hole is arranged on the knife edge, the upper edge and the lower edge of the conducting wire tube are provided with installing holes, the back part of the conducting wire tube is provided with a groove, the conducting wire tube and the knife edge are in split structures, the conducting wire tube is provided with a knife edge groove on the end surface at one side, the appearance of the knife edge is in a structure with symmetrical left side and right side, a through hole is arranged in the center part of the knife edge, and is arranged in an outline range relative to the conducting wire hole, the dimension of the through hole is matched with the dimension of steel bars in different specifications, both sides of the through hole are symmetrically provided with nail holes, and the knife edge is fixed inside the knife groove of the conducting wire tube through screws. The conducting wire tube and the knife edge of the utility model are in the split structures, and in addition, the screws are adopted for connection, so the service life of each part can be greatly prolonged. For the steel bars in different specifications, the conducting wire tube does not need to be replaced, only the knife edge with the through holes in different dimensions needs to be replaced, and the number of required spare parts can be effectively decreased. The conducting wire tube or the knife edge can be singly replaced when being damaged, and the maintenance cost is reduced.

Description

The hoop bender Combined knife

Technical field

The utility model relates to a kind of stirrup bender, the fixed cutting tool on particularly a kind of digital control steel bar hoop bender.

Background technology

Along with the development of building industry, the use amount of steel wire binding bar enlarges gradually, and the application of stirrup bender is more and more general.Existing digital control steel bar hoop bender is cooperated bar cutting by cutting knife behind the product bending forming.The conductor barrel of existing fixed cutting knife and the edge of a knife are connected to an integral body, as accompanying drawing 1, shown in Figure 2.The cutting knife that needs the integral replacing endoporus to vary in size for the reinforcing bar of different-diameter.But in use wearing and tearing maximum is edge of a knife part, and the conductor barrel part is complete substantially, as the integral replacing fixed cutting tool, can increase the spare part cost, causes unnecessary waste.

Summary of the invention

The purpose of this utility model provides a kind of hoop bender Combined knife, and the fixed cutting tool that solve on the existing digital control steel bar hoop bender needs integral replacing, increases spare part cost techniques problem.

For achieving the above object, the utility model adopts following technical scheme:

This hoop bender Combined knife, comprise the conductor barrel and the edge of a knife, be provided with wire guide one between the end face of conductor barrel both sides, the edge of a knife is provided with through hole, lower limb is provided with installing hole on the conductor barrel, the conductor barrel rear portion is provided with groove one, it is characterized in that: the conductor barrel and the edge of a knife are for dividing body structure, conductor barrel is provided with edge of a knife groove in a side end face, and edge of a knife profile is the left-right symmetry structure, and its middle part has through hole, be provided with in the profile scope of the relative wire guide of through hole, the size of through hole matches with the rebar sizes of different size, is provided with the nail hole in the through hole bilateral symmetry, and the edge of a knife is fixed in the edge of a knife groove inside of conductor barrel by screw.

Through hole on the described edge of a knife does not overlap with the axle center of wire guide.

Compared with prior art the utlity model has following characteristics and beneficial effect:

The conductor barrel of the present utility model and the edge of a knife are the branch body structure, and adopt screw to connect.Parts adopt the split manufacturing, can adopt different materials for the parts of different service conditions and different abrasion conditions, improve the service life of each part greatly.For the different size reinforcing bar, can not need the restringing tube, only need to change the edge of a knife that endoporus varies in size, effectively reduce required spare part quantity; When conductor barrel or edge of a knife damage, can change separately, reduce maintenance cost.

The edge of a knife of the present utility model adopts symmetrical structure, continues to use after near after moving cutting knife one lateral wearing rotatable 180 °.
