Abstract
The invention discloses a kind of broken and boring tool of anti-rear end split, including connection handle, the front end of the connection handle to be provided with operation head, and it is its tail end to define end of the operation handle away from the operation head, and the tail end of the connection handle is wound with macromolecular fibre silk.Broken and boring tool, the tail end of the anti-rear end split of the present invention are not easy to cleave, extend service life.
Description
Technical field
The present invention relates to broken and boring tool technical field, specifically, be related to it is a kind of it is anti-after end split broken and
Boring tool.
Background technology
In pavement breaking, housing demolition is broken and mining during, it is necessary to use quartering hammer.Existing quartering hammer
Including drill steel, drill steel includes drill steel body and drill head, and drill steel directly contacts in shattering process with broken object, stress compared with
Greatly, the drill steel tail end power that is hit is larger, therefore requires higher to drill steel pliability and wearability.At present, by taking drill steel
Be carbonized quenching technical, improves the pliability and wearability of drill steel, but existing carbonization quenching technical is impermeable to drill steel quenching, most
The big carbonization depth of quenching can only achieve 0.6mm, make carbonization quenching layer relatively thin, in actual crushing operation, the easy stress of drill head
Collapse broken rupture, end of the drill steel body away from drill head, the i.e. easy stress splitting of tail end of drill steel so that the service life of drill steel
Do not grow.Similarly, there is such a problem in drill bit of the drill bit of probing, impact drill etc..
The content of the invention
The technical problems to be solved by the invention are：There is provided a kind of tail end be not easy to cleave, extend service life it is anti-after
The broken and boring tool of the anti-rear end split of end split.
In order to solve the above technical problems, the technical scheme is that：
A kind of broken and boring tool of anti-rear end split, including connection handle, the front end of the connection handle are provided with operation head,
It is its tail end to define end of the operation handle away from the operation head, and the tail end of the connection handle is wound with macromolecular fibre
Silk.
Preferably, circumferentially face offers annular groove on the lateral wall of the tail end of the operation handle, and the macromolecule is fine
Dimension silk is wound in the annular groove.
Preferably, circumferentially face offers at least twice annular groove, the macromolecule on the lateral wall of the operation handle
Filament is wound in the annular groove.
Preferably, the filametntary outer application of annular groove inner macromolecule has one layer of frp layer.
Preferably, the surface of the frp layer is not higher than the top surface of the annular groove.
Preferably, the broken and boring tool of the anti-rear end split is crushing hammar drill rod.
Preferably, the broken and boring tool of the anti-rear end split is drill bit.
After employing above-mentioned technical proposal, the beneficial effects of the invention are as follows：
Broken and boring tool, the tail end of drill steel body of the anti-rear end split of the present invention are wound with macromolecular fibre silk.
The tail end of drill steel is set to be not easy to cleave when being hit.
The present invention it is anti-after end split broken and boring tool, offer ring on the lateral wall of the tail end of drill steel body
Connected in star, the macromolecular fibre silk are wound in the annular groove so that in actual use, will not be because of drill steel
Frequent movement and wear macromolecular fibre silk.
