Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
With reference to shown in Fig. 1~Fig. 3, the gear buckle assembly in one embodiment one provided by the invention is detained including bottom plate 1 and gear
2, the both ends of gear button 2 are connected by die 3 in bottom plate 1, and gear button 2 is door shape, and bottom plate 1 is equipped with multiple through holes, the material of gear button 2
For 38MnVS；Through hole is used for mounting base 1, and gear button 2 and the lock tongue of car door lock coordinate, for lockking lock tongue.
Further, one jiao of the upper end of gear button 2 is equipped with chamfering；By the setting of chamfering, it is easier the lock tongue of car door lock
It slips into gear button 2.
Further, through hole is countersunk head through hole.
Further, in embodiment two, as shown in figure 4, gear button 2 includes two montants, the lower end of two montants passes through
Die 3 is connected with bottom plate 1, cross bar is connected between two montants, two montants are telescopic rod.
Further, telescopic rod includes upper boom 4 and lower beam 5, and upper boom 4 is socketed with lower beam 5, and upper boom 4 can be stretched along lower beam about 5
Contracting is adjusted, and casing 6 is equipped between upper boom 4 and lower beam 5, and casing 6 is connected by screw thread with lower beam 5, and tightening casing 6 makes lower beam 5
Upper end tightens, and upper boom 4 is locked by casing 6, realizes that the position between upper boom 4 and lower beam 5 is fixed, is adjusted by revoling tube 6
The position of upper boom 4, so as to adjust the position of cross bar；When the lock tongue of car door lock has abrasion, the position of adjustable cross bar is fitted again
Answer lock tongue.
A kind of technique for manufacturing above-described gear buckle assembly, comprises the following steps：
1) bottom plate 1 and gear button 2 are completed；
2) both ends for keeping off button 2 are riveted by die 3 and bottom plate 1；
3) the gear button 2 after riveting and bottom plate 1 are electroplated；Complete part storage.
The operation principle of the present invention：
Existing gear buckle assembly need to be heat-treated the explanation of --- shot-peening --- correction three process：
Intensity before heat treatment：SCM435 or SWRCH35k materials behaviors are cold-drawn, its tensile strength is 450MPa at this time；Gear
When button 2 laterally loads, gear button 2 is by shearing force, and design, which calculates, keeps off the transverse load allowable of button 2 as 5.8KN, and far smaller than design will
Seek 10.8KN, it is therefore desirable to gear buckle assembly is heat-treated, to improve the tensile strength of gear button 2.
Intensity after heat treatment：Heat treating regime generally using the air-cooled technique of 850 ° of quenching+400 ° of oil coolings tempering, quenching and
Tempering is heated using meshbeltfurnace.Buckle assembly tensile strength is kept off after heat treatment and reaches 1100MPa, calculates the permission of gear button 2
Transverse load is 14.18KN, can reach the design requirement of transverse load 10.8KN.Therefore SCM435 or SWRCH35k materials must
It can be only achieved design requirement load after must being heat-treated.
It is heat-treated the loosening problem brought：
1 material of bottom plate is 20# steel plates, and gear 2 materials of button are SCM435 or SWRCH35k low-alloy rod irons；According to carbon iron balance
Figure knows, the 20# steel austenite structures transition temperature of bottom plate 1 is 855 ° during heating, gear button 2CM435 or SWRCH35k steel Ovshinskies
The temperature of body structural transformation is 800 °, and when carrying out Quench heating according to above-mentioned heat treating regime, 1 part tissue of bottom plate will not be sent out
Raw transformation, big variation will not occur for volume, and austenite structure can be changed by keeping off 2 part tissues of button, and volume can become larger；
1 part tissue of bottom plate will not change when being put into oil groove rapid cooling, and keeping off 2 part tissues of button can be turned by austenite structure
Become martensitic structure, volume becomes smaller.Therefore gear 2 components of button can cause to loosen at riveting in heat treatment.
In order to solve the problems, such as to be loosened after being heat-treated, it is necessary to increase punching press correcting process；During additionally, due to heat treatment, part
Surface can generate different degrees of oxide skin, influence the processing of process below, therefore increase blasting process is needed to make a return journey after heat treatment
Except the oxide skin of heat treatment.
The intensity of buckle assembly is kept off in the present invention：
A kind of new 2 component of gear button is devised, gear button 2 uses 38MnVS materials, condition of delivery cold-drawn, and tensile strength is
865MPa；Design calculates transverse direction allowable and is loaded as 11.16KN, more than design requirement laterally loading 10.8KN, therefore can meet
Design requirement, need not carry out heat treatment reinforcement, and optimization gear 2 component process flows of button are：Neck material --- riveting --- electricity
Plating --- storage.
Improve production efficiency
Above is only presently preferred embodiments of the present invention, cannot limit the interest field of the present invention with this certainly,
Therefore the equivalence changes made according to scope of the present invention patent, still belong to protection scope of the present invention.
