Abstract

The utility model discloses a novel combined cutting knife of a hoop bender. The novel combined cutting knife of the hoop bender comprises a conductor barrel and a cutter point, wherein a lead hole is formed between two lateral end faces of the conductor barrel; a through hole is formed in the cutter point; a mounting hole is formed at each of the upper and lower edges of the conductor barrel; a groove is arranged at the rear part of the conductor barrel; the conductor barrel and the cutter point are in split structures; a cutter point groove is arranged at one lateral end face of the conductor barrel; the shape of the cutter point is in a left and right symmetrical structure; the through hole is at the middle part; the through hole is arranged relative to the outline range of the lead hole; the size of the through hole is matched with sizes of rebars in different specifications; tack holes are symmetrically distributed at two sides of the through hole; and the cutter point is fixed inside a cutter point groove of the conductor barrel by a bolt. The conductor barrel and the cutter point disclosed by the utility model are in split structures and connected by the bolts. Therefore, the service life of each spare part can be greatly improved; the conductor barrel does not need to be replaced as to rebars of different specifications; only cutter points with through holes in different sizes need to be replaced; the quantity of required equipments can be effectively reduced; the conductor barrel or the cutter point can be independently replaced when being damaged; and the maintenance cost is reduced.

Description

The novel Combined knife of hoop bender
Technical field
The utility model relates to a kind of stirrup bender, particularly the fixed cutting tool on a kind of digital controlled steel hoop bending machine.
Background technology
Along with development of construction, the use amount of steel wire binding bar enlarges gradually, and the application of stirrup bender is more and more general.Existing digital controlled steel hoop bending machine is coordinated bar cutting by cutting knife after the product bending forming.The conductor barrel of existing fixed cutting tool 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 substantially complete, as the integral replacing fixed cutting tool, can increase spare parts cost, causes unnecessary waste.
Summary of the invention
The purpose of this utility model is to provide the novel Combined knife of a kind of hoop bender, and the fixed cutting tool that solve on existing digital control hoop bender needs integral replacing, increases the technical problem of spare parts cost.
For achieving the above object, the utility model adopts following technical scheme:
the novel Combined knife of this hoop bender, comprise 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, on conductor barrel, lower limb is provided with installing hole, the conductor barrel rear portion is provided with groove one, it is characterized in that: conductor barrel and the edge of a knife are Split type structure, conductor barrel is provided with edge of a knife groove one section side, edge of a knife profile is the left-right symmetry structure, its middle part has through hole, arrange 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, be provided with in the through hole bilateral symmetry and follow closely the hole, the edge of a knife is inner by the edge of a knife groove that screw is fixed in conductor barrel.
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:
Conductor barrel of the present utility model and the edge of a knife are Split type 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, greatly improve the service life of each part.For the reinforcing bar of different size, can not need the restringing cylinder, only need to change the edge of a knife that endoporus varies in size, effectively less required spare part quantity; Can change separately when conductor barrel or edge of a knife damage, 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 °.

The specific embodiment
Embodiment is referring to shown in Fig. 3-7, and the novel Combined knife of this hoop bender comprises conductor barrel 1 and the edge of a knife 2, is provided with wire guide 3 one between the end face of conductor barrel both sides, and the edge of a knife is provided with through hole 4, and the through hole 4 on the edge of a knife does not overlap with the axle center of wire guide 3; On conductor barrel, lower limb is provided with installing hole 5, the conductor barrel rear portion is provided with groove 8 one, it is characterized in that: conductor barrel 1 and the edge of a knife 2 are Split type structure, conductor barrel is provided with edge of a knife groove 9 in a side end face, and edge of a knife profile is the left-right symmetry structure, and its middle part has through hole 4, arrange in the profile scope of the relative wire guide 3 of through hole, the size of through hole matches with the rebar sizes of different size, is provided with in through hole 4 bilateral symmetry and follows closely hole 7, and the edge of a knife is fixed in edge of a knife groove 9 inside of conductor barrel by screw 6.
Shown in Fig. 3-5, wire guide 3 dimensional requirements of described conductor barrel 1 can be held two Φ 10mm Ribbed Bar simultaneously, realize the general of two Φ 6mm, Φ 8mm, Φ 10mm and single Φ 12mm Ribbed Bar, 4 of through holes on the described edge of a knife 2 are according to two Φ 6mm, Φ 8mm and two Φ 10mm, reach single Φ 12mm and be divided into several specifications, only need to change the edge of a knife of different size when changing different reinforcing bar.
Referring to Fig. 6, shown in Figure 7, the described edge of a knife 2 shape left-right symmetry, upset ° can continue to use after a lateral wearing.
