Description
Technical field
The present invention relates to stainless steel riveting fields, and in particular to a kind of multistage riveting method of high-hardness stainless steel hinge.
Background technology
The requirement of outdoor equipment hinge is：Corrosion Protection is provided simultaneously with size is smaller.It is above-mentioned in order to meet
It is required that existing outdoor equipment hinge is needed using the higher stainless steel of hardness.Stainless steel hinge includes stainless steel shaft and stainless
Steel page board, the single head (i.e. 1 end) of stainless steel shaft are provided with bulging flower, and the drum of stainless steel shaft is spent through the technology that presses based on metal plate,
It is connect with page board and fixed.
But there are following defects for existing stainless steel hinge：
(1) stainless steel shaft and stainless steel page board are prepared using powder metallurgical technique, and manufacturing cost is very high.
(2) the mostly of bearing load that press of metal plate are axial loads, often inapplicable outdoor equipment hinge, because single head
Riveting once undertakes normal load, by as highly unstable cantilever design, along with hinge is when long-time is in movement
The abrasion and impact being subject to, these can reduce the intensity of hinge, and then increase the crash rate of hinge.Therefore, existing stainless steel
The intensity of hinge is relatively low, and service life is shorter.
Invention content
For defect in the prior art, present invention solves the technical problem that being：How stainless steel hinge is improved
Intensity.When the stainless steel shaft that multistage of the present invention presses bears normal load, cantilever beam structure will not be become, intensity is very high, into
And extend the service life of stainless steel hinge.
To achieve the above objectives, the multistage riveting method of high-hardness stainless steel provided by the invention, includes the following steps：
S1：Suppress at least 2 circle drum flowers in an axial direction on stainless steel shaft, the drum of the top is spent positioned at the top of stainless steel shaft,
The drum flower of bottom is sequentially reduced from top to bottom positioned at the bottom end of stainless steel shaft, the outer diameter of all drum flowers, goes to S2；
S2：The stainless steel hinge being adapted to stainless steel shaft is prepared, stainless steel hinge is spent corresponding part with each drum, is provided with
Press hole, goes to S3；
S3：Stainless steel hinge is fixed on jig, the riveting hole of aperture maximum is upward, by the drum of stainless steel shaft bottom
Flower after sequentially passing through riveting hole from top to bottom, reaches installation site, and installation site is spent pair for the drum of stainless steel hinge and bottom
The hole that presses answered, goes to S4；
S4：By all drum flowers of stainless steel shaft, riveting to corresponding riveting hole.
Based on the above technical solution, the stainless steel shaft and stainless steel hinge are prepared using precision casting technology.
Based on the above technical solution, the outer diameter difference of adjacent 2 drum flowers is 0.3~0.5mm in S1.
Based on the above technical solution, the outer diameter difference of adjacent 2 drum flowers is 0.4mm in S1.
Based on the above technical solution, the outer diameter of the drum flower of the top described in S1 is 3.7mm, and the drum of bottom is spent
Outer diameter be 3.4mm.
Based on the above technical solution, press described in the S2 aperture in hole is less than the outer diameter of corresponding drum flower and is more than
The outer diameter of the lower section drum flower of corresponding drum flower.
Compared with prior art, the advantage of the invention is that：
(1) with it is of the prior art it is single-ended press compared with, stainless steel hinge of the invention is pressed using multistage, and multistage presses
Press hole and stainless steel shaft fastening it is reliable, when the stainless steel shaft that multistage presses bears normal load, cantilever beam knot will not be become
Structure.Therefore the present invention is greatly improved the intensity of stainless steel hinge, extends the service life of stainless steel hinge.
(2) stainless steel shaft in the present invention and stainless steel hinge are prepared using precision casting technology, with using in the prior art
Powder metallurgical technique prepares stainless steel shaft and is compared with stainless steel page, the stainless steel shaft and stainless steel hinge prepared using precision casting technology
Cost it is very low.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and embodiments.
The multistage riveting method of high-hardness stainless steel, includes the following steps in the embodiment of the present invention：
S1：It is shown in Figure 1, suppress at least 2 circle drum flower 1a (being 2 circles in the present embodiment) in an axial direction on stainless steel shaft 1,
The drum flower 1a of the top is located at the top of stainless steel shaft 1, and the drum flower 1a of bottom is located at the bottom end of stainless steel shaft 1, all drum flowers
The outer diameter of 1a is sequentially reduced from top to bottom.The outer diameter differences of adjacent 2 drums flower 1a is 0.3~0.5mm in the present embodiment, the present embodiment
In for 0.4mm, the outer diameter of the drum flower 1a of the top is 3.7mm, and the outer diameter of the drum flower 1a of bottom is 3.4mm, goes to S2.
S2：It is shown in Figure 2, the stainless steel hinge 2 being adapted to stainless steel shaft 1 is prepared, stainless steel hinge 2 is spent with each drum
1a corresponds to part, is provided with the hole 2a that presses, and the aperture in the hole that presses is less than the outer diameter of corresponding drum flower 1a and more than corresponding drum flower 1a's
The outer diameter (flower 1a is roused during to press can pass through the not corresponding hole 2a that presses to reach designated position) of lower section drum flower 1a, goes to
S3。
S3：Referring to shown in Fig. 2 and Fig. 3, stainless steel hinge 2 is fixed on jig (must be to every section of riveting during multistage riveting
The bottom in pressure hole is supported, and prevents from deforming under weight), the riveting hole of aperture maximum is upward, by the drum of 1 bottom of stainless steel shaft
Flower 1a after sequentially passing through riveting hole from top to bottom, reaches installation site, and installation site is stainless steel hinge 2 and the drum of bottom
The corresponding hole 2a that press of flower 1a；Each drum flower 1a also reaches respective installation site at this time, goes to S4.
S4：Referring to shown in Fig. 2 and Fig. 3, all drums of stainless steel shaft 1 are spent into 1a, riveting to corresponding riveting hole.
With it is of the prior art it is single-ended press compared with, the stainless steel hinge in the present embodiment is pressed using multistage, multistage pressure
Riveting press hole 2a and stainless steel shaft 1 fastens reliably, when the stainless steel shaft 1 that multistage presses bears normal load, will not become outstanding
Arm girder construction.Therefore the present invention is greatly improved the intensity of stainless steel hinge, extends the service life of stainless steel hinge.
Stainless steel shaft 1 and stainless steel hinge 2 in the present embodiment are prepared using precision casting technology, with using in the prior art
Powder metallurgical technique prepares stainless steel shaft 1 and is compared with stainless steel page, and the stainless steel shaft 1 and stainless steel prepared using precision casting technology is closed
