Abstract

The machining technics of the gear axle on the diesel engine is: A cutting material, cutting the round steel into pices for use; B. heated squeeze, put those pieces of material into the mould, under the condition of 650-800 deg. C. 1000-1500 mpa, the pieces of the material are squeezed into a shape with a blind hole inside the top, and the cascade axis fixed on the slot for connecting the handle is squeezed; C. Coarse process, lathe the reverse angle, seal ring slot, cutting fold slot, key mill slot, mill and cut the arch at the slot bottom by using the special mould; D. Using the special grinding wheel to grind the two external circless of the cascade axle.

Description

The processing technology of diesel engine starting gear shaft
Affiliated technical field
The present invention relates to a kind of processing technology of gear shaft, especially the processing technology of diesel engine starting gear shaft.
Background technique
Be applicable to the diesel engine starting gear shaft of S195, S1100, S1105, S1110, normal bavin L28, L30 type, processing technology commonly used adopts round steel as shaft blank, through cylindrical turning, tool withdrawal groove, seal groove, chamfering, drilling blind hole, keyseat, connection positioning spigot, working procedure processing such as grinding cylindrical are made finished product, the processing technology complexity, the expense of taking a lot of work material, manufacture cost is higher.Chinese patent CN2589688Y discloses a kind of diesel engine starting gear shaft blank, with round steel via the die forging once-through, being swaged into first base substrate 1 and second base substrate 2 is on the same center line and connects to one, end face at first base substrate 1, be provided with center hole, the end face of second base substrate 2 is provided with the shaft blank of blind hole.Carry out metal cutting processing again with this shaft blank and can save certain raw material, that reduces the diesel engine starting gear shaft to a certain extent adds the technology complexity, but still need it is carried out cylindrical lathe cutting processing, especially the Milling Process of the connection positioning spigot that is connected with manual starting grip of diesel engine starting gear shaft, the Milling Process surplus is big, the expense of taking a lot of work material, manufacture cost is higher.
Summary of the invention
The objective of the invention is to disclose a kind of diesel engine starting gear shaft processing technology, to overcome existing diesel engine starting gear shaft processing technology complexity, the expense of taking a lot of work material, the higher deficiency of manufacture cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of diesel engine starting gear shaft processing technology, have following technological process: a, fracture, and round steel is broken into the segment raw material for standby; B, warm extrusion are put into mould with the segment raw material, and at 650~800 ℃, warm extrusion becomes in the upper end under 1000~1500Mpa condition blind hole, and the upper end-hole warm extrusion goes out the step axle shaft blank that crank handle connects the positioning spigot groove; C, roughing, car chamfering, seal groove, tool withdrawal groove, keyseat is with the bottom land circular arc of special-purpose profile milling moulding connection seam groove; D, grinding, with two cylindricals of special grinding wheel, a grinding diesel engine starting of frock gear shaft, the moulding warehouse-in.
Further: described step a, fracture, for φ 35mm round steel being broken into the segment raw material of long 70mm.
Again further: described step b, warm extrusion, for the segment raw material is put into mould, at 650~800 ℃, warm extrusion becomes lower end φ 30mm, long 50mm under 1000~1500Mpa condition, upper end φ 35mm, long 56mm, blind hole φ 20mm, dark 52mm in the upper end, the upper end-hole warm extrusion goes out the shaft blank that crank handle connects the positioning spigot groove.
The invention has the beneficial effects as follows that after the round steel warm extrusion was molded, cylindrical was smooth, do not need to carry out turning processing, it is less that crank handle connects positioning spigot groove machining allowance again, and the grinding cylindrical is two cylindricals with special grinding wheel, a grinding diesel engine starting of frock gear shaft, labor and material saving, low cost of manufacture.
Description of drawings

Embodiment
A kind of diesel engine starting gear shaft processing technology as shown in Figure 1 has following manufacturing process: a, fracture, φ 35mm round steel is broken into the segment raw material for standby of long 70mm as shown in Figure 2; B, warm extrusion, the segment raw material is put into mould, under 650~800 ℃, warm extrusion becomes lower end φ 30mm, the long 50mm shown in Fig. 3,4 under 1000~1500Mpa condition, upper end φ 35mm, long 56mm, blind hole φ 20mm, dark 52mm in the upper end, the upper end-hole warm extrusion goes out the shaft blank that crank handle connects the positioning spigot groove.C, roughing, car chamfering, seal groove, tool withdrawal groove, keyseat, the bottom land circular arc with special-purpose profile milling moulding connection seam groove is processed into the diesel engine starting gear shaft shown in Fig. 5,6; D, grinding, with two cylindricals of special grinding wheel, a grinding diesel engine starting of frock gear shaft, the moulding warehouse-in.
Because the shaft blank that adopts warm extrusion technology to make, cylindrical is smooth, does not need to carry out turning processing again, so raw material can adopt φ 35mm round steel to be broken into the long segment raw material of 70mm, waste of raw materials is few, has reduced the turnery amount; Crank handle connects the positioning spigot groove and only need get final product with the circular arc of special-purpose pattern moulding connection seam groove, and machining allowance is less, has significantly reduced the milling workload; The grinding cylindrical is two cylindricals with special grinding wheel, a grinding diesel engine starting of frock gear shaft, high working efficiency, and finished product accuracy is higher.
