Abstract

The utility model relates to a high-speed rock drill with long service life. The rock drill comprises a grab handle, a cylinder body and a machine head. A grab handle sleeve is sheathed on the grab handle; a valve bank, a piston and a spiral rod are arranged in the cylinder body; a silencing cover is arranged at the position of an air outlet on the cylinder body, and a bit shank sleeve is arranged in the machine head; and high-rigidity anti-wear layers are respectively arranged at the outer surfaces of the valve bank, the piston and the spiral rod. With the characteristics of long service life and low failure rate, the high-speed rock drill with long service life is a regeneration product of the present rock drill.

Description

The long-life high speed rock drill
Technical field
The utility model relates to a kind of long-life high speed rock drill.
Background technology
Hammer drill be a kind of on rock the machine in Drilling hole, its groundwork principle is with calming the anger as power, move back and forth by the passive valve control piston, piston impact drilling tool cutter crushed rocks during stroke; During backhaul, piston drives the certain angle of drilling tool revolution, and continuous impact, revolution make drilling tool dig out circular big gun hole on rock.High speed rock drill is in work, and moving component is very easy to wearing and tearing in running up, form fault.
Summary of the invention
The purpose of this utility model provides the long-life high speed rock drill that a kind of life-span is long, fault rate is low.
For achieving the above object, the utility model is by the following technical solutions:
Long-life high speed rock drill described in the utility model comprises lever, cylinder body and head, be set with the lever cover on the lever, be provided with valve group, piston and rifle bar in the cylinder body, exhaust ports on cylinder body is equipped with silencer cover, be provided with the bit shank cover in the head, it is characterized in that: the external surface of described valve group, piston and rifle bar all has wearing layer.
The wearing layer of the external surface of valve group 2 is ionic nitriding wearing layers; The wearing layer of the external surface of piston 4 is deep-hardening layer, high hardened layer, and case depth is 2.5mm, and carbide morphology is in the 1-2 level; The wearing layer of the external surface of rifle bar 5 is ionic nitriding layers.
This long-life high speed rock drill long service life, fault rate are low, are the renewal products of existing hammer drill.
Description of drawings
Accompanying drawing is the longitudinal sectional view of a kind of embodiment of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in drawings, long-life high speed rock drill described in the utility model comprises lever 7, cylinder body 8 and head 9, be set with lever cover 1 on the lever 7, be provided with valve group 2, piston 4 and rifle bar 5 in the cylinder body 8, exhaust ports on cylinder body 8 is equipped with silencer cover 3, be provided with bit shank cover 6 in the head 9, it is characterized in that: the external surface of described valve group 2, piston 4 and rifle bar 5 all has the high hardness wear-resisting layer.
Wherein, the wearing layer of the external surface of valve group 2 is ionic nitriding layers; The wearing layer of the external surface of piston 4 is that deep-hardening layer, high case depth reach 2.5mm, and carbide morphology is in the 1-2 level; The wearing layer of the external surface of rifle bar 5 is ionic nitriding layers.These high-intensity wearing layers, the protection parts can not wear and tear too early, have effectively improved application life, reduce fault rate.
The structure of other parts of the utility model is a known technology, and this repeats no more again.
