Bight radius of formation of each wedge shape bulge-structure 22a and 23a and each wedge shape sunk structure 22b and 23b is 0.11 millimeter fillet R.It is 0.11 millimeter fillet R that the bight of each wedge shape bulge-structure 22a of the following stated and 23a and each wedge shape sunk structure 22b and 23b also all forms a radius.
The manufacture method of support frame 21 before below will illustrating.At first the method for L shaped member 21a and 21b is made in explanation.From the angle that is easy to process, preferably adopt stainless steel as the material of making L shaped member 21a and 21b.Adopt press, produce L shaped member 21a and 21b by the stainless steel band steel board of coiling 24 is carried out punching press.At this moment, as shown in Figure 3, leave clearance T between following metal stamping and pressing 25 that is used for described band steel board 24 is carried out punching press and last metal stamping and pressing 26, the width of described clearance is about 12% of used band steel board thickness (for example 1 millimeter).At this, the width of the clearance T that stays is about generally (being about 6%) 2 times.As shown in Figure 4, in end of each L shaped member 21a that obtains by punching press and 21b-for example at the bulge-structure 22a of L shaped member 21a, can form saggingly and constitute a fraction of notch 27 in its end and wedge surface 28 by L shaped member 21a surface, the width of wedge surface 28 is about 10% of used stainless steel strip sheet metal thickness (for example 1 millimeter).
Now in conjunction with the accompanying drawings 5 and accompanying drawing 6A-6C explanation before the manufacture method of support frame 21.At first, shown in Fig. 5 and 6A, make the junction surface 22 relative configurations of L shaped member 21a and 21b, the notch 27 that makes L shaped member 21a is with respect to the wedge surface 28 of L shaped member 21b and the notch 27 of the wedge surface 28 relative L shaped member 21b that make L shaped member 21a, then, L shaped member 21a and 21b are placed on down in the metal stamping and pressing 29, will go up metal stamping and pressing 30 and be placed on L shaped member 21a and the 21b, make L shaped member 21a and 21b pressing.Fig. 5 is the zoomed-in view at junction surface 22, and Fig. 6 A, 6B and 6C are the cross-sectional view of A-A line among Fig. 5.When L shaped member 21a and the configuration of 21b subtend, it is the 0.05-0.1 mm clearance that a width is arranged between their junction surface 22.The bigger steel manufacturings of hardness such as alloy tool steel are adopted in following metal stamping and pressing 29 and last metal stamping and pressing 30.On the lower surface of last metal stamping and pressing 30, dispose parallel with the end face of L shaped member 21a and 21b, with described end face the linear projection 30a and the 30b of certain distance are arranged.As shown in Figure 7, it is the fillet of R that the base portion both sides of linear projection 30a form radius, and linear projection 30a has only drawn among Fig. 7.When the thickness of L shaped member 21a and 21b was the 0.4-1 millimeter, the height of linear bulge-structure 30a and 30b was the 0.2-0.3 millimeter.Generally speaking, above-mentioned height is the 20-30% of member thickness, and radius of corner R is 0.1 millimeter.
Shown in arrow among Fig. 6 B, last metal stamping and pressing 30 applies external force (pressure) by the top to L shaped member 21a and 21b, and the end of L shaped member 21a and 21b is pressed near under its effect mutually.Generally, outer the exerting pressure that is used to push metal stamping and pressing is about ten tons of weights, and the pressure of last metal stamping and pressing is about 1 second action time.Because each linear bulge-structure 30a and 30b have fillet R, therefore linear bulge-structure 30a and 30b will be pressed into L shaped member 21a and 21b.As a result, be equivalent to the part of linear bulge-structure 30b and the notch 27 that wedge surface 28 is pushed to L shaped member 21b among the L shaped member 21a, the notch 27 of the L shaped member 21b of wedge surface 28 incisions; Simultaneously, the notch 27 that is pushed to L shaped member 21a corresponding to part and the wedge surface 28 of linear bulge-structure 30a among the L shaped member 21b, and the notch 27 of the L shaped member 21a of wedge surface 28 incisions.Like this, bulge-structure 22a and sunk structure 22b form mechanical engagement, shown in Fig. 6 C.Here, linear bulge-structure 30a and 30b are pressed into the upper surface of L shaped member 21a and 21b from the both sides at junction surface, are the groove 31 and 32 of V-arrangement substantially thereby form the cross section, shown in Fig. 6 C.After the processing of the junction surface 23 of L shaped member 21a and 21b being finished shown in 6A, 6B and 6C, second embodiment as above-mentioned prior art, adopt pressing equipment that the crooked limit on each limit is bent, just finished processing and manufacturing with the same front baffle 21 of front baffle shown in Figure 29 2.Also can adopt said method manufacturing with the central frame of central frame 3 same shapes shown in Figure 29.

Clearly, the present invention is not limited to the foregoing description, is not deviating under the scope of the invention and the main idea, can make some variation and modification to it.For example, in the above-described embodiments, linear bulge-structure coordinates at top die, dip mold or up and down on two pressing molds, and the wedge surface that makes a member is to the notch motion of another member and cut this notch, thereby can form the groove in V-arrangement cross section when member engages near the junction surface; But the present invention is not limited only to this version.For example shown in the image pattern 21,22 bulge-structure 22a centre disposes bellmouth 72 at the junction surface
1-72
3As shown in figure 22, can be formed with pyramidal hole at position corresponding to junction surface 22 bulge-structure 22a base portions.In addition, as shown in figure 23, by near junction surface 22, forming the groove 31 and 32 in V-arrangement cross section, because of intersect vertically the non-expectation that extruding produces of the end face 21a1 of L shaped member 21a and 21b and 21b1 and junction surface 22 is out of shape (A and B part among Figure 23) and can be inhibited.
In the above-described embodiments, member is only formed by member itself at the junction surface of configuration relatively, but the present invention is not limited to this version.For example, as shown in figure 24, engaging and can realize between the member 74a that makes by higher hardness materials such as iron and the 74b by the fastener of making than low-durometer material by aluminium etc. 75.Iron material more cheaply but relatively be difficult to processing adopts said structure just can adopt more iron material to make the display support frame.When engaging, as shown in figure 24, when fastener 75 was subjected to the extruding of member 73A and 74b, as shown in figure 25, because the hardness of fastener 75 is lower, fastener might produce than bigger bulging deformation shown in Figure 23 (A among Figure 25 and B part).Therefore, when engaging, mold pressing should adopt anchor clamps to prevent that fastener 75 from protruding into the member 74a of formation display frames outside and the lateral surface of 74b, and should shear member along dotted line among the figure, make the width dimensions that constitutes display frames inside meet designing requirement shown in Figure 25.For this reason, the reply bulging deformation is estimated to some extent in advance, and is made the width of framework be slightly larger than former design size.At this, adopt common mould pressing method during mold pressing, as described in top embodiment 1-6.
Adopt the reasons are as follows of above-mentioned joint method: because the inside of display frames will contact with the LCD display panel, the inside dimension of display support frame requires to require more strict than its external dimensions.Therefore, as shown in figure 24, by prior art, after the making of finishing the rectangular display framework, need shear part (the A part among Figure 25) shown in Figure 25 dotted line on the member 74a that constitutes framework inside and the 74b end face, so that the width dimensions of display frames adheres to specification.Therefore, the described manufacture method of the foregoing description does not cause more inconvenience, because prior art also needs the operation of clip frame inside dimension originally.In addition, framework is engaged and to shown in Figure 25 dotted line the part shear after, further form a fillet structure R shown in Figure 26 (for example 0.5 millimeter) in the framework bight, its purpose is to prevent to abrade metal stamping and pressing that is used to shear and the intensity that improves framework.Can adopt common technology in the bight the inboard described fillet structure R of formation, for example engage after the operation method that adopts in method used in shearing or channel member and the L shaped structure manufacture etc. in the various embodiments described above.
Present embodiment is different with the various embodiments described above; by top die, dip mold or up and down on two pressing molds the position corresponding to fastener form various bulge-structures and when engaging, two members interfixed, present embodiment can suppress the non-expectation distortion that causes because of factors such as member extruding.
In the present embodiment, adoptable fastener shape not only is confined to form shown in Figure 24, also can adopt fastener shown in Figure 27 76
1-76
