Description
Technical Field
The utility model relates to an engineering machine tool accessory field, concretely relates to high strength jump bit.
Background
The impact hammer is a shield machine for excavating tunnel subways, a tunneling machine for underground mining and a road planing machine for repairing road surfaces, is used for crushing a rock surface, a mine surface and a tunneling head of the road surface, is an important part of the equipment and is also a vulnerable part; the front end of jump bit is the working portion, the rear end is carrier portion, the during operation need constantly with the working portion of jump bit front end with the broken rock stratum of rock contact, because of the operating mode is harsh, the working portion of jump bit is very easily worn and torn, the cone in its wearing and tearing result is firstly drops from the carrier portion in the working portion, make whole jump bit scrap, secondly the cone intensity of working portion is not high leads to warping, the jump bit after the deformation can become blunt, be difficult to cut mountain gravel fast, cause work efficiency low, the energy that the machine consumed increases.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to solve the above-mentioned deficiencies of the prior art,
the utility model provides a high strength jump bit, the toper mechanism of its jump bit is inlayed outward and is had the carbide, whole has promoted the intensity of jump bit and rock contact surface, improve jump bit life, and add the energy-absorbing piece between jump bit and mounting groove, thereby transmit impact energy to the energy-absorbing piece, make energy-absorbing piece arc dispersion transmit the energy-absorbing piece outer wall, in order to prolong the impact action time, reduce the impact acceleration, make the impact stress that the jump bit received reduce, the life of jump bit has been prolonged.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a high strength percussion hammer, includes work portion and carrier portion, its characterized in that: the utility model discloses a work piece, including work portion, impact head, mounting groove, shock head, mounting groove, shock head, the work portion front end is equipped with the impact head, the front end of impact head forms conical structure, conical structure inlays and has the carbide, the carrier portion is equipped with the mounting groove, the one end that the impact head corresponds the mounting groove is equipped with the mounting structure of cooperation mounting groove, the impact head rear portion is fixed in the mounting groove.
The high-strength impact hammer may further comprise: the mounting groove is provided with an installation groove, the installation groove is provided with an installation hole, the installation hole is provided with an energy absorption block, the installation hole is provided with a concave cavity, the installation structure is inserted into the concave cavity, the outer wall of the energy absorption block is connected with the installation groove in a butting mode, and the concave cavity is connected with the impact head in a butting mode, so that impact force received by the impact head is transmitted to the outer wall of the energy absorption block.
