Description
Technical field
The invention belongs to fulcrum bar of headrest of automobile processing technique fields, and in particular to a kind of fulcrum bar of headrest of automobile arc making device.
Background technique
With the development of the automobile industry, people are higher and higher to the quality requirements of automobile, in past last decade, China
Auto output achieve and significantly increase, as the improvement of people's living standards, the comfort level of automobile also increasingly by
The care of consumer, especially car seat headrest can provide head support, so that driver obtains one for driver
Comfortable sitting posture is typically fabricated as slight curving shape to make the head of driver obtain support, headrest stay well,
Existing production method is to fix strut one end, then carries out punching press to the strut other end, so that strut becomes curved shape,
But the knee of the strut Jing Guo this punching press is single, and bent angle is uneven, and since strut is made of rigid material, to strut
Punching press dynamics is easily damaged strut when larger, and when smaller to the punching press dynamics of strut, strut is not flexible, need Multi-step forming at
Type, so needing to design, a radian is uniform, the good strut arc making device of punching press effect.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to the status of the prior art, and provide a kind of fulcrum bar of headrest of automobile punching
Arc device.
The technical scheme of the invention to solve the technical problem is: proposing a kind of fulcrum bar of headrest of automobile arc making dress
It sets, comprising: pedestal, the upper end offer several the first stamped grooves, and each first stamped groove is arcuate structure, described
First stamped groove is for putting strut to be punched；
Pressing plate is set to the pedestal upper end and is flexibly connected with the pedestal, and the pressing plate lower end is provided with several
Second stamped groove, each second stamped groove are respectively positioned on above corresponding first stamped groove, and second stamped groove is
Arcuate structure and identical as the first stamped groove radian；
Strut can be struck out to the shape with the first stamped groove identical radian measure when the pressing plate moves down.
In a kind of above-mentioned fulcrum bar of headrest of automobile arc making device, the pedestal upper end is provided with link block, the connection
Spring is installed on block side end face, the spring one end is connected with carrier block, offers bearing groove on the carrier block.
In a kind of above-mentioned fulcrum bar of headrest of automobile arc making device, the pedestal upper end is provided with guide post, on the pressing plate
Guide hole is offered, the guide post activity is inserted in the guide hole.
Compared with the prior art, the advantages of the present invention are as follows the fulcrum bar of headrest of automobile arc making devices to strike out strut
The more uniform shape of radian, the good forming effect of strut largely reduce the damage to strut, and punching press number is few, at
Type is high-efficient.
Detailed description of the invention
Fig. 1 is the three-dimensional view of this fulcrum bar of headrest of automobile arc making device；
Fig. 2 is the three-dimensional view of pressing plate；
In figure, pedestal 1, the first stamped groove 2, pressing plate 3, the second stamped groove 4, link block 5, spring 6, carrier block 7, bearing groove
8, guide post 9, guide hole 10, strut 11.
Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As depicted in figs. 1 and 2,11 arc making device of this fulcrum bar of headrest of automobile, comprising: pedestal 1, the upper end offer several
First stamped groove 2, each first stamped groove 2 is arcuate structure, and first stamped groove 2 is for putting strut to be punched
11；Pressing plate 3 is set to and 1 upper end of pedestal and is flexibly connected with the pedestal 1, and 3 lower end of pressing plate is provided with several articles the
Two stamped grooves 4, each second stamped groove 4 are respectively positioned on corresponding first stamped groove, 2 top, second stamped groove 4
For arcuate structure and identical as 2 radian of the first stamped groove；Strut 11 can be struck out when the pressing plate 3 moves down
With the shape of 2 identical radian measure of the first stamped groove.
The part to be formed of strut 11 is placed in the first stamped groove 2, and pressing plate 3, which moves down, is able to drive the second stamped groove 4
The first stamped groove 2 is moved closer to, when pressing plate 3, which is moved to, to be in contact with pedestal 1, the second stamped groove 4 is pushed against in 11 upside of strut
On face, the first stamped groove 2 is resisted against on the downside of strut 11, under the action of the downward power of pressing plate 3,4 energy of the second stamped groove
Enough 11 deformation of strut is driven extremely, so that the radian of strut 11 and 4 radian of the second stamped groove are just as the second stamped groove 4 is to strut 11
Active force be evenly distributed in the upper side of strut 11, so the stress of strut 11 is more uniform, and then when guaranteeing punching press not
Strut 11 can be damaged, and strut 11, when being stamped, the entirety of strut 11 is enabled to strut by stamping press in this way
11 moldings faster, reduce punching press number, after strut 11 forms, radian is identical as the radian of the first stamped groove 2, thus can
The radian of strut 11 is enough controlled by the radian of the first stamped groove 2, and then can guarantee that the radian of the strut 11 after punching press is uniform.
1 upper end of pedestal is provided with link block 5, and spring 6 is installed on 5 side end face of link block, and described 6 one end of spring connects
It is connected to carrier block 7, offers bearing groove 8 on the carrier block 7.
Bearing groove 8 guarantees strut 11 for situations such as carrying 11 end of strut, preventing punching press front support rod 11 from shaking
Position to be punched is in always in the first stamped groove 2,11 positional shift of strut when preventing punching press and to damage caused by strut 11.
Radian is formed after 11 punching press of strut, so the position that the end of strut 11 is located on bearing groove 8 must change,
When 11 end position of strut changes active force can be generated to carrier block 7, the active force of carrier block 7 acts on spring 6,
So that deformation occurs for spring 6, and then provides certain moving distance for the variation of 11 end position of strut, strut can be prevented in this way
Strut 11 damages caused by the reaction force that 11 ends are subject to is excessive.
1 upper end of pedestal is provided with guide post 9, and guide hole 10 is offered on the pressing plate 3, and 9 activity of guide post is inserted in described
In guide hole 10, when pressing plate 3 moves up and down, guide hole 10 is moved along guide post 9, guarantees that the movement routine of pressing plate 3 is stablized, and then guarantee
Second stamped groove 4 can guarantee the punching press effect of strut 11, prevent pressing plate 3 from damaging branch by pressure always situated in 2 top of the first stamped groove
Bar 11.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
Generation, defined range that however, it does not deviate from the spirit of the invention.
