Description

Car seat headrest bar bending die has

Technical field

This utility model belongs to technical field of mold, specifically, particularly to a kind of car seat headrest bar bending die tool.

Background technology

At present, the curved processing of rushing of car seat headrest bar is typically on punch press to be undertaken by mould.Existing bending die tool is made up of upper die and lower die two large divisions, upper and lower mould carry out matched moulds rush curved in, the head rest pole of seat is supported by two mandrels, during due to punching press, head rest pole impact is bigger, and directly firmly contact between head rest pole with mandrel, the part that head rest pole contacts with mandrel is so very easily caused to damage, thus causing workpiece to do over again or scrapping.

Utility model content

Technical problem to be solved in the utility model is in that to provide a kind of bending die that can effectively prevent car seat headrest bar from damage occurring tool.

The technical solution of the utility model is as follows: a kind of car seat headrest bar bending die tool, the fixing die shank in the middle position of cope match-plate pattern end face, the middle part of cope match-plate pattern bottom surface arranges punch, described cope match-plate pattern be connected with die, die is fixed on lower bolster, described die offers the adaptive groove matched with punch, the both sides, front and back of this adaptation groove respectively arrange one group of groove, often group groove is divided into two, left and right, it is characterized in that: in each groove, be equipped with roller, four rolling presses matrix distribution, described roller is installed on mandrel by bearing, mandrel and die fix, and the excircle of roller offers annular groove.

Adopting above technical scheme, set up four rolling on die, roller can rotate relative to mandrel.Before rushing curved chair headrest, the front and back shaft of two pole crooks to be rushed of head rest pole all snaps in the annular groove of corresponding roller, head rest pole is positioned by roller by annular groove, to prevent head rest pole from occurring left and right crooked or skew, in the process rushing curved head rest pole, the impulsive force that head rest pole is subjected to passes to roller, makes roller rotate, and damages thus effectively prevent head rest pole with roller contact place.

In order to simplify structure, convenient for assembly, be arranged on same mandrel with two rollers in group, this mandrel and die tight fit.

The right and left on rear side of described die is symmetrical arranged guide pillar, and this guide pillar is perpendicular to lower bolster, and the lower end of guide pillar fixes with lower bolster, and the upper end of described guide pillar is stretched in guide pin bushing, and both are slidably matched, and described guide pin bushing is fixed on the bottom surface of cope match-plate pattern.Above structure guide pin bushing matches with guide pillar, plays the effect of guiding, to guarantee that cope match-plate pattern only moves at vertical direction, thus what ensured head rest pole rushes curved quality, meets the requirement of uniform production.

Beneficial effect: this utility model alleviates impact force when head rest pole rushes curved by the rotation of roller, effectively prevent head rest pole to damage, eliminate the disadvantage that workpiece is done over again or scrapped, there is reasonable in design, simple in construction, the feature such as transformation is easy, improvement cost is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the axonometric chart of apparent direction before this utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figure 1 and Figure 2, the fixing die shank 2 in the middle position of cope match-plate pattern 1 end face, die shank 2 is connected with the clamping device on punch press, makes cope match-plate pattern 1 can move up and down on punch press.Arranging punch 3 at the middle part of cope match-plate pattern 1 bottom surface, punch 3 is perpendicular to cope match-plate pattern 1, can be structure as a whole, it would however also be possible to employ bolt is fixed between punch 3 and cope match-plate pattern 1.

As shown in Figure 1 and Figure 2, being connected with die 4 at cope match-plate pattern 1, die 4 is fixed on lower bolster 5.Offering the adaptive groove 4a matched with punch 3 on die 4, the both sides, front and back of this adaptation groove 4a respectively arrange one group of groove 4b, and groove 4b is symmetrical for two groups, front and back, and often group groove 4b is divided into two, left and right, and each groove 4b all extends along the longitudinal direction.Being equipped with roller 6 in each groove 4b, four rolling 6 is by matrix distribution, and roller 6 is installed on mandrel 7 by bearing, and is arranged on same mandrel 7 with two rollers 6 in group, and mandrel 7 and die 4 are tightly fixed.Offering annular groove 6a on the excircle of each roller 6, the width of annular groove 6a is slightly larger than the diameter of head rest pole 10.

As it is shown in figure 1, the right and left on rear side of die 4 is symmetrical arranged guide pillar 8, this guide pillar 8 is perpendicular to lower bolster 5, and the lower end of guide pillar 8 fixes with lower bolster 5.The upper end of guide pillar 8 is stretched in guide pin bushing 9, and both are slidably matched, and guide pin bushing 9 is fixed on the bottom surface of cope match-plate pattern 1.

Operation principle of the present utility model is as follows:

Before rushing curved chair headrest 10, the front and back shaft of 10 two pole crooks to be rushed of head rest pole all snaps in the annular groove 6a of corresponding roller 6, head rest pole 10 is positioned by roller 6 by annular groove 6a, cope match-plate pattern 1 moves downward together with punch 3, punch 3 enters in the adaptive groove 4a of die 4 and carries out matched moulds, and in this process, head rest pole 10 is rushed curved, and the impulsive force that head rest pole 10 is subjected to passes to four rolling 6, making roller 6 rotate, damaging with roller 6 contact position thus effectively prevent head rest pole 10.

The structure that this utility model does not describe is same as the prior art, and therefore not to repeat here.
