Description
Technical field
The present invention relates to for rushing point methods in aero-engine miniature parts process, particularly rush in point process
The uncontrollable problem of positioning, punching point appearance and size etc..
Background technology
In aircraft industry, the fewer of point technique is rushed, but some special parts need to use and rush point design and processing work
Skill；Punching point technique exist one it is important the problem of, exactly rush in point process it is difficult to ensure that rush appearance a little and rushing the correlation put
Size requirement, the existing point methods that rush are to realize the technique using the simple method for tapping punch, are unable to control completely
The appearance and relative dimensions of point are rushed, it is very high so as to cause the rejection rate of product；With the development of Aeroengine Industries, to product
There is higher requirement, continue meet performance using original processing method, it is therefore necessary to improve punching point matter
Amount.
Invention content
The technical problem to be solved by the present invention is to：It provides a kind of for the auxiliary mould of complex profile punching point and punching point side
Method realizes control punching point appearance, and spot size is rushed in guarantee, so as to improve product qualification rate.
Technical scheme is as follows：
A kind of auxiliary mould for complex profile punching point, the location type face including being located at tooling lower end, the location type
Face is consistent with parts to be processed external form facial contour, and positioning through hole, positioning through hole are provided between location type face and tooling upper surface
Both sides respectively there are one guide hole, and the axis of guide hole is parallel to the axis of positioning through hole.One according to claim
Kind rushes the auxiliary mould of point for complex profile, it is characterised in that：The axis of the axis of the positioning through hole and two guide holes
It is coplanar.
The axial line distance of the axis of described two guide holes to positioning through hole is equal.
The tooling upper surface is plane.
The internal diameter of the positioning through hole is less than the internal diameter of pin hole on part.
It is a kind of that point methods are rushed using above-mentioned auxiliary mould, include the following steps：
Auxiliary mould is fixed on by location type face, positioning through hole and positioning pin at part point-type face to be rushed by step 1；
Step 2 selects the punch to match with institute's communications centre point, is inserted into along guide hole until bottom；
Step 3 taps punch and is bonded to punch tip with auxiliary mould upper surface；
Step 4, removes auxiliary mould, and completion is rushed a little.
The present invention positions the position of punching point by location type face and positioning through hole, ensures punching point by two guide channels
Validity selects punch, by the tip shape and length that control punch according to punching point tooling and the relative dimensions of required punching point
Spend the quality to ensure punching point.
The auxiliary punching point tooling of the present invention, which solves, existing rush point methods can not to be accurately positioned and rush an appearance uncontrollable
Processing problem；This tooling is made of location hole, guide hole and fit type face, passes through type face and location hole accurate positioning twice
Punching point position is fixed, guide hole can guarantee the depth of punching point, and applicability is wide, easy to operate；Meanwhile this tooling is simple to manufacture,
It is reusable, greatly reduce production cost.
Description of the drawings
Fig. 1 is the part schematic diagram for carrying out punching point；
Fig. 2 is part punching point process schematic representation in Fig. 1；
Fig. 3 is auxiliary mould structure diagram；
Fig. 4 is auxiliary mould post-assembled state schematic diagram.
Specific embodiment
Point methods are rushed to this below in conjunction with the accompanying drawings to be described in detail：
As shown in Figure 1, being certain trestle component, punching point surface is a curved surface.
As shown in Fig. 2, for part punching point process schematic representation, logical overshoot point is needed to realize that pin is fixed on by interference fit
Inside slot.Wherein d is the diameter of pin；A represents that the taper (60 ° are rushed a taper for certain part) of punching point is ensured by tool；H is
Rush the depth of point；Dot center and the distance of bolt bore edges are rushed in l expressions；hlThe distance exported for pin end face to pin hole；H and l
Size determine that their relationship is shown in Table 1, and also needs to meet h according to pin diameter dl≤ l, wherein b sizes (l) are without checking.
1 unit of table is millimeter
| Pin diameter d | h | l |
| 0.6-1.0 | 0.15-0.3 | 0.3 |
| 1.6-3.0 | 0.4-0.7 | 0.5 |
| 4.0-5.0 | 0.8-1.1 | 0.8 |
| 6.0-8.0 | 1.2-2.0 | 1.5 |
As shown in figure 3, for the auxiliary mould of complex profile punching point, the location type face 1 including being located at tooling lower end, positioning
Type face 1 is consistent with parts to be processed external form facial contour, and positioning through hole 2 is provided between location type face 1 and tooling upper surface, positioning
The both sides of through-hole 2 are respectively there are one guide hole 3, and the axis of guide hole 3 is parallel to the axis of positioning through hole 2.The axis of positioning through hole 2
The axis co-planar of line and two guide holes 3.The axial line distance of the axis of two guide holes 3 to positioning through hole 2 is equal.Tooling upper end
Face is plane.The internal diameter of positioning through hole 3 is less than the internal diameter of pin hole on part.
As shown in figure 4, plugging positioning pin by location type face 1 and in positioning through hole 2 to position the position of punching point, two are led
Approaching channel 3 can ensure the force direction of punch and the validity of punching point, according to punching point tooling and the related ruler of required punching point
It is very little to select punch, punching point technique shown in Fig. 2 can be realized by the tip shape and length that control punch.
Concrete operation step is as follows：
1) punching point auxiliary mould is fixed on part correct position by location type face 1, positioning through hole 2 and positioning pin；
2) punch that selection and institute's communications centre point match is inserted into bottom along guide hole 3；
3) punch is tapped to be bonded with auxiliary mould upper surface to punch tip；
4) auxiliary tool is removed, completion is rushed a little.
