Abstract
The utility model discloses a driving long shaft of a tapping machine. The driving long shaft of the tapping machine comprises a shaft body. A whole quenching layer which is formed through quenching treatment is arranged on the surface of the shaft body. Due to the fact that the surface of the driving long shaft of the tapping machine is provided with the whole quenching layer which is formed through heat treatment, the driving long shaft of the tapping machine has the advantages of being high in hardness, not prone to being abraded and long in service life.
Description
Technical field
The utility model relates to a kind of perforator and drives major axis.
Background technique
Perforator is that a kind of novel pipeline is installed facility, can branch line is installed or pipeline is carried out Maintenance and Repair at the main line pipeline.Because the live axle length of perforator is longer, general surface is difficult to carry out the integrity Quenching Treatment, causes the major axis surface hardness lower, in use easily weares and teares, and working life is short.
The model utility content
The technical problems to be solved in the utility model is: overcomes the deficiency in the prior art, provides a kind of hardness high, and difficult the wearing and tearing, the perforator of long service life drives major axis.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of perforator drives major axis, comprises axis body, and described axis body surface has the integrity quench hardened case that forms by Quenching Treatment.
Furtherly, described quench hardened case hardness is HRC61, and thickness is 0.8mm.
The beneficial effects of the utility model are: the perforator that the utility model provides drives the major axis surface and has the integrity quench hardened case that forms through heat treatment, hardness is higher, be difficult for wearing and tearing and long service life occur, changed the situation that present major axis class outer surface can only be modified.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. axis bodies, 2. quench hardened cases among the figure
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of perforator as shown in Figure 1 drives major axis, comprises axis body 1, has the integrity quench hardened case 2 that forms by Quenching Treatment on described axis body 1 surface, and these quench hardened case 2 hardness are HRC 61, and thickness is 0.8mm.Owing to the existence of axis body 1 surface hardening layer 2 has improved the surface hardness of axis body 1, after driving major axis and being installed on the perforator, can improve the use wear resistance of axis body 1, not fragile, prolong 1 working life of axis body.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
Claims (2)
1. a perforator drives major axis, comprises axis body (1), it is characterized in that: described axis body (1) surface has the integrity quench hardened case (2) that forms by Quenching Treatment.
2. perforator according to claim 1 drives major axis, and it is characterized in that: described quench hardened case (2) hardness is HRC61, and thickness is 0.8mm.
