Display frame forming method

The present invention relates to a method of forming a frame, and more particularly to a method of forming a display frame.

Referring to Figures 1, 2, a known frame 1 of a display is generally a square frame and includes four connected frame strips 11. Each of the frame strips 11 includes a first sheet 111 and a second sheet 112 joined at 90 degrees. In general, the frame 1 of the display is manufactured by first cutting a frame sheet into a plurality of sheets intended to form the frame strips 11, and bending each sheet one by one to form the first sheet. The sheet 111 and the second sheet 112 are used to obtain the frame strips 11. Finally, the strips 11 are arranged one above the other, and the adjacent portions of the strips 11 are welded and joined by welding. The frame 1 of the square frame is obtained.

In the above manufacturing method, a plurality of independent and separated sheets are first cut, so that each sheet has to be bent one by one, and each side is cut to obtain the frame 11 and then necessary. The separate pieces are assembled into a four-square shape. The manufacturing process of this method is cumbersome, has many steps, and takes time and labor.

Accordingly, it is an object of the present invention to provide a method of forming a display frame that simplifies the process steps and that is simple and time-saving.

Therefore, the method for molding the display frame of the present invention is used for fabricating a display frame comprising four frame strips integrally connected into a square frame. The method for forming the display frame comprises the step A: bending a frame plate Folded to form two joined sheets. Step B: cutting each of the sheets to form three notches, the notches defining the four connected pieces, each of the pieces having two sides on opposite sides, each The three notches of the plate respectively correspond to the positions of the three notches of the other plate, and the four plate portions of each plate respectively correspond to the positions of the four plate portions of the other plate and Integrally coupled, each of the panel portions of each panel and the panel portion of the other panel coupled thereto form one of the frame strips of the display frame. Step C: bending the plates along the notches so that each plate extends into a square frame, and each side of each plate portion and one of the adjacent other plate portions Side adjacent. Step D: Fixing the adjacent sides of the adjacent sides to fix the sheets.

The effect of the invention is that: by the frame material having sufficient size, a bending process is equivalent to completing the bending of the four frame strips of the display frame, and after cutting the gaps, The plates of the frame sheet are bent to form a square frame, which is then fixed by welding. The invention can save the steps of cutting multiple times to form a plurality of independent frame strips in the past, and also improve the process that the previous frame strips must be separately bent and processed, and the steps of reassembling the independent frame strips are omitted, the invention The process steps can be simplified, and the method is simple and time-saving.

Referring to FIGS. 3-6, an embodiment of a method for forming a display frame of the present invention is used to fabricate a display frame 2, which includes four frame strips 21 integrally connected into a square frame, which is the embodiment. The molding method consists of the following steps:

Step 41: A roll of frame sheet 22 is provided, which is wound around a rotating shaft 3. The frame sheet 22 may be made of a metal material and may be in the form of a sheet and may be provided in a roll. The frame sheet 22 is gradually rolled out in a winding direction L. At the same time as the roll is discharged, the portion where the frame sheet 22 is unwound is bent by mechanical means to form two boards which are connected at approximately 90 degrees. Slice 23. One of the plates 23 extends horizontally to the left and right, and the other plate 23 extends downward from the front edge of the horizontally extending plate 23. Further, the sheets 23 are formed to extend in a sheet shape along the winding direction L.

Step 42: Cut three notches 230 on each of the plates 23, and the notches 230 further define the plate 23 with four connected plate portions 231, each of which has two Side 232 on the opposite side. Preferably, each side edge 232 is a beveled edge extending at an angle of approximately 45 degrees, which facilitates subsequent attachment and attachment of each side edge 232 to the side edge 232 of the adjacent other panel portion 231. At this time, the two plates 23 are still integrally connected, and the three notches 230 of each plate 23 respectively correspond to the positions of the three notches 230 of the other plate 23, and the four of each of the plates 23 The plate portions 231 are respectively connected to the positions of the four plate portions 231 of the other plate piece 23 and are integrally connected. Each of the panel portions 231 of each of the panels 23 and the panel portion 231 of the other panel 23 connected thereto constitute a frame strip 21 of the display frame 2. In addition, one end of the frame strip 21 closest to the rotating shaft 3 has an intended cutting point 24.

Step 43: The plates 23 are bent along the notches 230 such that each of the plates 23 extends into a square frame, and each side 232 of each plate portion 231 is adjacent to another plate. One side 232 of the sheet portion 231 is adjacent. Since each side edge 232 of the present embodiment has a beveled edge extending at an angle of 45 degrees, it can correspond to the extended form of the side edge 232 of the adjacent other panel portion 231 to form a complete and beautiful seam. On the other hand, if the adjacent side edges 232 of the adjacent plate portions 231 are not aligned or have redundant portions, the shaping process may be additionally performed to remove excess portions of the side edges 232.

Step 44: welding the adjacent side edges 232 by welding to fix the plates 23 into a square frame, thereby completing the display frame 2.

It should be noted that, before the step 43 is performed, the plate 23 may be cut from the rolled frame plate 22 along the predetermined cutting portion 24, or after the step 43 is completed, The plates 23 are then cut, or the display frame 2 can be cut and separated from the rolled frame sheets 22 after the welding in step 44 is completed, and then the molding process of the next display frame 2 can be continued.

Since the present invention firstly takes the frame plate 22 of sufficient size to form the four frame strips 21 of the display frame 2, it is equivalent to forming the two plates 23 by bending the frame plate 22 once. After the four frame strips 21 of the display frame 2 are bent, and after the notches 230 are formed by cutting, the plates 23 of the frame sheet 22 are bent to form a square frame, and then welded and fixed. That is, the production is completed. Therefore, compared with the conventional molding method, the four frame strips 21 are integrally connected in the whole process, so that the steps of cutting a plurality of times to form a plurality of independent frame strips can be omitted, and the previous frame strips must be improved. The process of bending the processing separately, and eliminating the steps of assembling the separate frame strips. Therefore, the invention can simplify the process steps, and the preparation method is simple and time-saving.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
