Abstract

The utility model discloses a split type cutter comprising three independent sections of cutting knives. Each section of cutting knife comprises a knife body and a cutting edge, and a plurality of bolt holes are arranged in the knife body of each section cutting knife. For the split type cutter, if damage appears on one section of cutting knife in use, the fixing bolt of the section of cutting knife can be disassembled independently so as to replace the section of cutting knife, and the other two sections of cutting knives are not influenced, thereby leading the maintenance to be more convenient, and lowering the cost.

Description

A kind of split type cutter

Technical field

The utility model relates to a kind of cutter, relates in particular to a kind of split type cutter.

Background technology

Existing titanium sponge sticks together to cut and uses hydraulic press, and its cutting knife adopts overall structure, and cutting knife and hydraulic press cutting knife slide block adopt bolt.Such cutting knife not only volume is big, and the cutting bad adaptability.In the operating process that the cutting sponge titanium sticks together, if hard-core cross section, titanium sponge middle part is big, hardness is high, and cutting knife can contact the turned or phenomenon of rupture of position appearance of hard core at the middle part in the operation process.The impaired part that the most seriously causes cutter to be scrapped of cutting knife concentrates in the 500-700mm scope of blade middle part in the practice, and the blade two ends extent of damage is less.In this case, because cutting knife is an overall structure, the user must stop production whole cutting knife is changed.Therefore, traditional overall structure blade changes in use that frequency is higher, the time between overhauls(TBO) is long, causes production cost higher, and productivity ratio descends.In sum, there are many shortcomings in the titanium sponge of the traditional integral structure cutting knife that sticks together, demands urgently improving.

The utility model content

The purpose of the utility model is exactly the problem that exists to prior art, a kind of convenient disassembly is provided, uses split type flexibly cutter.

Above-mentioned purpose realizes through following proposal:

A kind of split type cutter is characterized in that, said split type cutter comprises independently three sections cutting knifes, and each section cutting knife includes cutter hub and blade, on the cutter hub of said each section cutting knife, is equipped with a plurality of bolts hole.

According to above-mentioned split type cutter, it is characterized in that the cutting knife that is positioned at two ends in said three sections cutting knifes is a symmetrical structure.

The beneficial effect of the utility model: the split type cutter of the utility model, wait in use if damage appears in certain section cutting knife, can dismantle the set bolt of this section cutting knife separately and change this section cutting knife, and not influence all the other two sections cutting knifes.Thereby make that maintenance is more convenient, and can reduce cost.

The specific embodiment

Fig. 1 is the overall structure of the split type cutter of the utility model, and it is made up of independently A section cutting knife 13, B section cutting knife 14 and C section cutting knife 15, includes cutter hub 1 and blade 2 above every section cutting knife, on cutter hub 1, is equipped with a plurality of bolts hole 3.A section cutting knife 13 is measure-alike symmetrical structures with C section cutting knife 15.

Referring to Fig. 2 and Fig. 3, A section cutting knife is made up of cutter hub 4, blade 5 and fixed-use bolt hole 6; Referring to Fig. 4 and Fig. 5, B section cutting knife is made up of cutter hub 7, blade 8 and fixed-use bolt hole 9; Referring to Fig. 6 and Fig. 7, C section cutting knife is made up of cutter hub 10, blade 11 and fixed-use bolt hole 12.Wherein, A section cutting knife is to be connected fixingly with the cutting knife slide block through 9 bolts hole, 6 usefulness bolts, when dismounting, tightens or unclamps this 9 connecting bolts; B section cutting knife is to be connected with the knife rest of cutting knife slide block through 6 bolts hole 9, when dismounting, tightens or unclamps this 6 connecting bolts; C section cutting knife is to be connected with the cutting knife slide block through 9 bolts hole 12, when dismounting, tightens or unclamps this 9 connecting bolts.

Wait in use if damage appears in certain section cutting knife, can dismantle the set bolt of this section cutting knife separately and change this section cutting knife, and not influence all the other two sections cutting knifes.

Claims

1. a split type cutter is characterized in that, said split type cutter comprises independently three sections cutting knifes, and each section cutting knife includes cutter hub and blade, on the cutter hub of said each section cutting knife, is equipped with a plurality of bolts hole.

2. split type cutter according to claim 1 is characterized in that, the cutting knife that is positioned at two ends in said three sections cutting knifes is a symmetrical structure.
