Detailed description of the invention
The invention will be further described for attached drawing, but the embodiments in the accompanying drawings do not constitute any limitation to the present invention.
Fig. 1 is the structural schematic diagram that one embodiment of the invention provides；
Fig. 2 is the side view that one embodiment of the invention provides；
Fig. 3 is the cross-sectional view of Fig. 2.
Specific embodiment
As shown in figs. 1-2, a kind of lamp body structure that one embodiment of the invention provides is without riveting column riveting set comprising main
Body 1, mold core 2, upper spring 3 and lower spring 4.The side of the main body 1 is equipped with upper mold 11 and lower die 12, and the upper mold 11 is equipped with circle
Hole 111, the lower die 12 are located at 11 lower section of upper mold.The mold core 2 passes through circular hole 111, and the mold core 2 is from the upper mold
11 top extends towards the direction of the lower die 12, and the top of the mold core 2 is equipped with pusher upper cover 21.3 sets of the upper spring exists
Outside the mold core 2, the upper spring 3 is clipped between the pusher upper cover 21 and the upper mold 11, and the diameter of the upper spring 3 is big
In the diameter of the circular hole 111, the upper spring 3 is avoided to stick into the circular hole 111, the pusher upper cover 21 and the upper bullet
Spring 3 is connected, and when the mold core 2 is pressed downward, the upper spring 3 respectively applies the pusher upper cover 21 and the upper mold 11
Elastic force.4 sets of the lower spring outside the mold core 2, the lower spring 4 is between the upper mold 11 and the lower die 12.It is logical
It crosses the upper spring 3 and the lower spring 4 cooperates, it is ensured that the mold core 2 can use described after having riveted to workpiece
The smooth material returned of elastic force of upper spring 3 and the lower spring 4 avoids causing the workpiece for completing riveting secondary effect, and entire dress
It is simple to set structure, it is at low cost.
As illustrated in fig. 1-3, the bottom end of the mold core 2 is higher than the bottom end of the lower spring 4, when the mold core 2 is pressed downward
When, the lower spring 4 can be contacted first with workpiece to be riveted, and after workpiece to be riveted has riveted, even if mold core 2 leaves riveting
Complete workpiece, the lower spring 4 can still act on the workpiece riveted.The lateral wall of the mold core 2 is equipped with junction 22,
The junction 22 is located at 11 bottom surface of upper mold to the middle position between 2 bottom of mold core, the junction 22 and institute
It states lower 4 phase of spring to fix, the junction 22 can be connected by way of welding or buckling with the lower spring 4, institute
It states lower spring 4 to be connected with the bottom surface of the upper mold 11, when the mold core 2 moves down, the junction 22 can also be followed
It moves down, at this point, the lower spring 4 of 22 or more the junction can be stretched, so that the mold core 2 generation is pulled back
Power, and the lower spring 4 below of the junction 22 will not generate deformation before touching workpiece to be riveted.
As illustrated in fig. 1-3, the main body 1 includes upper fixed seat 13, attachment base 14 and lower fixed seat 15, fixed
Seat 13 is connected with 14 upper surface of attachment base by screw, and the lower surface of the lower fixed seat 15 and the attachment base 14 is logical
It crosses screw to be connected, the main body 1 is split as three parts, wherein the attachment base 14 can be according to the reality of workpiece to be riveted
Situation replaces the attachment base 14 of corresponding size and size.The upper mold 11 is fixed on the side of fixed seat 13, described
Lower die 12 is fixed on the side of the lower fixed seat 15.The lower die 12 is located at immediately below the upper mold 11, and the lower die 12 is set
There is support column 121, the support column 121 is for placing workpiece to be riveted, the central axis and the circular hole of the support column 121
111 central axis, the mold core 2 is generally cylindrical, and the center of the central axis of the mold core 2 and the support column 121
Axis is coaxial, it is ensured that in riveting process, the mold core 2 can accurately rivet rivet on workpiece to be riveted.The lower fixed seat
15 bottom is equipped with location hole 151, and the location hole 151 can be inserted on outer liquid press or assign into external workbench
On, it is ensured that upper mold 11 described in riveting process will not shake, to influence to rivet effect.
As illustrated in fig. 1-3, in actual use, outer liquid press is first got out, lower fixed seat 15 is fixed on
On outer liquid press, workpiece to be riveted is got out above lower fixed seat 15；By the central axis of circular hole 111 and support column 121
Central axial alignment is overlapped, and the lower surface of attachment base 14 is fixed together with lower fixed seat 15 by pin screw, attachment base
14 upper surface is fixed together with upper fixed seat 13 by pin screw；Workpiece to be riveted is placed on lower die 12 and lower spring 4
Between, rivet is got out below mold core 2, rivet can be transmitted by external automation equipment, or be placed by manpower,
Then power being acted in pusher upper cover 21 by outer liquid press, mold core 2 declines, and mold core 2 drives lower spring 4 to move down,
Lower spring 4 first compresses workpiece to be riveted, continues to depress pusher upper cover 21, lower spring 4 in the partial shrinkage below of junction 22, under
Spring 4 is elongated in the part of 22 or more junction, and mold core 2 is by rivet on workpiece to be riveted；Outer liquid press is withdrawn to apply
It is added in the power of pusher upper cover 21, mold core 2 ramps up, and the lower spring 4 starts to reset in the part below of junction 22, lower spring
4 bottom end continues to push down the workpiece riveted, and partial reset of the lower spring 4 in 22 or more junction shortens, and entirely lower spring 4 is right
Mold core 2 applies a upward power, and mold core 2 continues under the action of upper spring 3 toward rising, mold core 2 and the workpiece for completing riveting
Separation then plays spring 4 to reset completely far from the workpiece riveted, lower spring 4 and upper spring 3, i.e., to guarantee that the material returned is smooth
Complete the riveting of workpiece.The present invention is after completing workpiece riveting, and workpiece surface is without core pulling nail and screw, good appearance, and opposite
For the previous method riveted using no core pulling nail and screw, the situation of anti-pine can be effectively reduced, improve safety coefficient, drop
Low manufacturing cost, entire riveting process is simple and fast, and built-up time is few, improves production efficiency.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
