Definitions
- the present invention relates to a method for manufacturing a sleeve member to be incorporated into various mechanical devices.
- an electromagnetic spool valve or a linear solenoid valve for controlling an automatic transmission incorporates a sleeve member that forms part of a hydraulic path (see Patent Document 1).
- the sleeve member has a cylindrical shape as a basic shape, and includes a port groove provided so as to communicate the outer peripheral surface and the inner peripheral surface thereof.
- the sleeve member is usually manufactured by cutting a rod-like or tubular material made of a metal material such as an aluminum alloy.
- a method of cutting using a material cast in a shape close to the final product is employed.
- the reference surface to be chucked is different between the inner peripheral processing and the outer peripheral processing, the accuracy of the coaxiality between the inner peripheral surface and the outer peripheral surface may not be sufficiently obtained.
- the present invention intends to provide a method for manufacturing a sleeve member that can improve a conventional manufacturing method and obtain a sleeve member with higher dimensional accuracy than the conventional one.
- One aspect of the present invention is a method of manufacturing a sleeve member that has a cylindrical shape and is formed by cutting an outer peripheral surface and an inner peripheral surface thereof.
- the material body is gripped by a lathe chuck and the outer peripheral surface of the thrown boss is cut to form a reference gripping surface,
- the reference gripping surface of the discard boss is gripped by a lathe chuck to cut the outer peripheral surface and inner peripheral surface of the material body, Thereafter, the discard boss portion is removed from the material main body.
- a material that is integrally provided with the discarded boss portion in the axial direction of the material body is used as a material before cutting. Then, before cutting the material body, the outer peripheral surface of the discarded boss portion is cut to form the reference gripping surface.
- the reference gripping surface is gripped by a lathe chuck and the material body is cut.
- the reference gripping surface provided on the discard boss portion is used. It can be carried out by gripping with a lathe chuck. As a result, the surface to be gripped by the chuck when cutting the material body can always be set to the same surface, and it is possible to prevent a processing shift due to a difference in the chuck gripping surface.
- the reference gripping surface of the thrown boss portion is present, so when cutting the inner peripheral surface of the material body, it is not necessary to grip the outer surface of the material body with a chuck. . Therefore, it is possible to avoid problems caused by cutting the material body in a state where the material body is deformed by the gripping force of the chuck.
- FIG. 3 is an explanatory diagram illustrating an outer shape of a material in the first embodiment. Explanatory drawing which shows the discard boss part processing of the raw material in Example 1. FIG. The explanatory view which looked at the state where the material is grasped with the chuck in Example 1 from the axial direction. FIG. 3 is an explanatory view showing a material main body processing of a material in Example 1. FIG. 3 is an explanatory diagram illustrating a material discarding boss portion removing process in the first embodiment. FIG. 3 is an explanatory view showing a cross-sectional shape of the obtained sleeve member in Example 1. FIG. 6 is an explanatory diagram showing a cross-sectional shape of a material in Example 2. Explanatory drawing which shows the time of the internal peripheral surface processing of the raw material main body of a raw material in Example 3. FIG.
- the material body is cut by gripping the reference gripping surface of the discarded boss portion provided in advance with a lathe chuck as described above.
- the processing of the material main body may be all performed with a single lathe, or may be performed with a plurality of separate lathes divided into a plurality of steps.
- the material of the material is not particularly limited, but various metal materials can be applied, for example.
- the aluminum alloy is relatively light and has high rigidity, and is suitable as a material for the sleeve member.
- Various materials can be applied as the aluminum alloy, and examples thereof include a high silicon aluminum alloy, ADC12, and ADC3.
- the material it is preferable to prepare a material produced by casting such as die casting.
- a material produced by casting By producing the material by casting, at least the material body can be easily brought close to the final product shape, and the yield can be improved. Further, according to casting, it is easy to produce a discarded boss portion.
- the reference end surface may be formed by cutting the axial end surface of the discarded boss portion.
- the reference gripping surface can be gripped by the chuck in a state in which the reference end surface of the discarded boss portion is in contact with the shaft end surface of the lathe at the time of subsequent processing to the material body, and more stable. A gripping state can be obtained, and the axial machining accuracy can be increased more than before.
- the axial length L 0 of the reference gripping surface and the total length L of the material can be in a relationship of 0.1L ⁇ L 0 ⁇ 0.3L.
- L 0 is less than 0.1 L, it is difficult to obtain a stable gripping force.
- L 0 exceeds 0.3 L, the stability in the gripping state is saturated, and the discarded boss portion becomes too large, which is not preferable in terms of material yield.
- the absolute value of the axial length L 0 of the reference gripping surface is preferably increased as the total length L of the material increases.
- the outer diameter dimension D 0 of the reference gripping surface and the outer diameter dimension D of the material body can be in a relationship of 0.5D ⁇ D 0 ⁇ 2.5D.
- the rigidity of the discarded boss portion can be set within an appropriate range, and the gripping state by gripping the reference gripping surface with the chuck can be stabilized. If D 0 is less than 0.5D, the discarded rigidity of the boss portion is lowered, a stable gripping force is difficult to obtain. On the other hand, when D 0 exceeds 2.5D, the discarded boss portion becomes too large, which is not preferable in terms of material yield.
- the absolute value of the outer dimension D 0 of the reference gripping surface is preferably increased as the outer dimension D of the material body is larger.
- the discard boss may be a hollow structure having a hollow inside.
- the discard boss when processing a sleeve member having a relatively small diameter, it is effective for stabilizing the gripping state to make the thrown boss portion larger in diameter than the sleeve member. In this case, the deterioration of the material yield can be suppressed by adopting the hollow structure as long as the rigidity of the discarded boss portion can be maintained.
- the discarded boss portion may be a solid structure having no cavity inside.
- the diameter of the sleeve boss can be made smaller than that of the sleeve member while ensuring rigidity by making the waste boss part a solid structure, and the material including the waste boss part. It is possible to suppress the outer diameter of the substrate from being increased more than necessary.
- the thickness is preferably about 1.5 mm to 7.0 mm.
- a larger diameter is preferable for cutting because the rigidity improvement effect is higher, but it causes deterioration of the material yield. It is preferable to set.
- the above manufacturing method can be applied when manufacturing sleeve members for various uses, but is particularly effective when manufacturing parts with high dimensional accuracy requirements.
- a high dimensional accuracy requirement for example, there is a sleeve member incorporated in a linear solenoid valve for automatic transmission control.
- a sleeve member incorporated in a valve that controls the amount and timing of engine intake and exhaust by hydraulic pressure a sleeve member incorporated in a hydraulic solenoid valve for industrial machinery, a sleeve member incorporated in a hydraulic solenoid valve for construction machinery,
- sleeve members incorporated into various pumps such as a fuel supply pump and an idling stop pump.
