And the grooving 3 of connection mounting hole 2.
Specifically, selection blanking first, that is, select blank of the suitable steel as piston 10, preferably FC300
Or 20Cr steel, its hardness is 20HRC-60HRC, then carries out blanking forming, is full circle at the piston mounting groove of blanking forming part
Hole 8, as shown in Fig. 2 now the external diameter of piston 10 is R1, R1 now is more than piston 10 external diameter end value R, i.e. R1 ＞ R.
Secondly, roughing is carried out, the inner peripheral surface 5 and outer peripheral face 6 to piston 10 carry out turnery processing, to the full circle in Fig. 2
Hole 8 carries out Drilling operation, and drill process obtains axially extending mounting hole 2 after terminating, as shown in figure 3, wherein drilling operating needs
Allowance is reserved for subsequent handling.
Again, piston 10 can be heat-treated, heat treatment can use tempering or vacuum hardening, to improve piston
10 overall performance.It is of course also possible to be first heat-treated to piston 10, then the inner peripheral surface 5 and outer peripheral face 6 of piston 10 are carried out
Turnery processing, the full-round hole 8 in Fig. 2 is drilled.
Then, two outer faces 7 of piston 10 are roughly ground, fraising processing is carried out to mounting hole 2 using reamer.
Then, Double face grinding is carried out to two outer faces 7 of piston 10, half then is carried out to the inner peripheral surface 5 of piston 10
Finishing.
Then, with the mounting hole 2 of top gem of a girdle-pendant processing technology machining piston 10, now mounting hole 2 or a full circle, such as Fig. 3 institutes
Show, while top gem of a girdle-pendant processing is carried out to the inner peripheral surface 5 of piston 10.
Then, the outer peripheral face 6 of piston 10 is roughly ground using grinding machine, the outer peripheral face 6 of piston 10 is then refined, such as Fig. 3
Shown, the outside dimension of piston 10 finished is R, and the distance of the central axis of distance of center circle piston 10 of mounting hole 2 is L, installation
The radius of hole 2 is r, then R ＞ L+r.It is of course also possible to be first ground to the outer peripheral face 6 of piston 10, then the top gem of a girdle-pendant is carried out to mounting hole 2
Processing.
Then, mounting hole 2 is cut using cutter, is formed through piston outer periphery face 6 and connect the grooving of mounting hole 2
3, slide plate is made way in the position of grooving 3, and as shown in fig. 4-5, mounting hole 2 forms the mounting groove for accommodating slide plate with grooving 3
1.Preferably for the mounting hole 2 for forming mounting groove 1, its cornerite should be greater than 180 °, in order to mounting groove 1 and slide plate preferably
It is be hinged.
Finally, deburring, cleaning are carried out to piston 10, the manufacturing process of piston 10 just terminates.
In brief, the mounting hole 2 for processing circle is first bored on piston 10, then the processing of correlation is carried out to mounting hole 2,
The mounting hole 2 of circle, is then cut into final mounting groove 1, so, it is possible to prevente effectively from going out by such as fraising, top gem of a girdle-pendant processing again
Cutting force energy imbalance when now drilling, using the high efficiency such as drilling, fraising, Honing process, inexpensive manufacturing process, just
The dimensional accuracy and surface quality of needs can be obtained.
The manufacture method of compressor piston 10 according to embodiments of the present invention, it is possible to achieve compressor piston 10 it is efficient
Rate, low cost processing, to obtain the dimensional accuracy and surface quality that need.
In some embodiments of the invention, in drill process, the allowance of mounting hole 2 is 0.05mm-0.5mm,
In order to subsequently be reamed to mounting hole 2, the top gem of a girdle-pendant processing.
Alternatively, after the heat treatment step, the hardness of piston 10 is 25HRC-60HRC, for example, heat treatment step it
Afterwards, the hardness of piston 10 can be 45HRC.
