Abstract
The invention discloses a sixth-engineering method for stamping an LED displayer back panel, and relates to a method for machining an LED displayer, in particular to a method for stamping by utilizing a sixth-engineering stamping die. The method comprises the first step of stamping the product appearance and an inner positioning hole, the second step of stamping a stamp mark, punching a clamping hook, thread rolling and segmenting, the third step of carrying out burr pressing on a hole and a formed edge obtained in the second step and meanwhile carrying out clamping hook forging, etching and bending, the fourth step of bending the periphery, the fifth step of stamping and cutting-out an opening in the middle, and the sixth step of carrying out the burr pressing on the opening in the middle. By means of the method, the procedure of pressing burrs on the opening in the middle can be achieved after bending while the working procedures are not increased, the yield of products can be improved, the number of the burrs can be reduced, and the quality of the products can be improved.
Description
Technical field
The present invention relates to a kind of processing of light-emitting diode display backboard, particularly a kind of method of utilizing stamping machine to carry out the processing of light-emitting diode display backboard.
Background technology
Light-emitting diode display (or LCD display) is a kind of flat panel display equipment, main devices is display panels, the backboard that also comprises the fixer crystal panel, this is a kind of parts of metal frame posture, be used for fixing liquid crystal panel, and be connected outside housing, can be described as " skeleton " of liquid crystal display, on backboard, have the details such as hole, grab, projection, groove, these details are all that punch process realizes.
Due to the backboard of frame-type, in punch process, can produce burr in the time of punching or opening, these burrs need processed.Existing processing method is reasonable is the dabbing thorn, can on stamping machine, complete.
The existing mach method of punching press of utilizing has: the method for 1, six engineering, by feeder, coiled strip is entered to stamping machine, and the first engineering is gone out product design, the positioned internal hole.The second engineering is played mint-mark, snap fit punching, section is poor.The 3rd engineering profile dabbing thorn, check card hook, mint-mark.After the 4th the all-round bending of engineering, adopt shown in Figure 2 the 5th engineering.The mould closure, patrix is descending, utilizes two long slipper push devices, and the slide block that drives counterdie closes up.The slide block on the left side moves to B from A, and the slide block on the right moves to D from C, thereby folds U-shaped bending.Then the 6th engineering gone out the middle opening (OPENING) of product again.Mould punching completes.
The way of 2, seven engineerings, be exactly on the basis of original punching press details and moulding, increases separately the step of a dabbing thorn.
The problem that prior art exists is: the burr of middle large opening can't be processed, and these burrs can produce scraping, thereby produce tiny scrap, and can produce trickle space between liquid crystal panel.Even tiny scrap can enter the interlayer of liquid crystal panel, produces light leakage phenomena, and display surface there will be bright spot.Have a strong impact on the quality of display.
Summary of the invention
The object of the invention is to the deficiency for the flow and method of the backboard of existing six engineering stamped liquid crystal displays, inventing a kind of is the method for six engineerings equally, the special deburring technique increased the opening broad in the middle of display backplane.
For this reason, technical scheme of the present invention is such: a kind of processing method for stamping of light-emitting diode display backboard of six engineerings, the process detail that described light-emitting diode display backboard has grab, sprouts, carves characters, middle part has opening, surrounding has all-round bending, and whole product carries out punch process with the diel of six engineerings, and the patrix of described diel is provided with a slide block and push rod, counterdie is provided with Bending punch, and the position of Bending punch is positioned at horizontal dead-centre position one side of slide block; Push rod and slide block have interlock; Step is 1: rush product design and positioned internal hole; 2, rush mint-mark, grab punching, sprout, section is poor; 3, the dabbing thorn is carried out to, the hook of checking card simultaneously, mint-mark and bending in the hole of step 2 and the edge of moulding; 4, the all-round bending of surrounding; 5, the opening in the middle of punching press cuts out; 6, middle opening is carried out to the dabbing thorn.
Method of the present invention can realize the operation to the dabbing thorn of middle opening in bending, and whole process remains six engineerings later, like this, do not need to increase extra equipment and operating personnel, but can improve the yield rate of product, reduce burr, improve the quality of products.
The accompanying drawing explanation
Fig. 1, the structure of display backplane.
Fig. 2, the structure of backboard bending part.
Fig. 3, the diel of existing six engineering impact styles.
Fig. 4, the structure enlarged drawing of the bending working portion of the diel of prior art.
Fig. 5, the diel of six engineering process for stamping of the present invention.
Fig. 6, the structure enlarged drawing of the bending working portion of diel of the present invention.
The specific embodiment
As Fig. 1, this display backplane that the present invention is suitable for, be a frame-shaped construction, and centre has large opening, and surrounding has the part of all-round bending, and the structure of dogleg section such as Fig. 2 are U-shaped bendings.Be divided into two steps and complete, 1. step is from 90 ° of dull and stereotyped bendings, becomes a right angle; 2. step by 90 ° of the bendings again of the part after bending, forms U-shaped.The process detail such as also have simultaneously grab on the display backplane of whole frame-shaped construction, sprout, carve characters, all adopt stamped.
Existing stamping procedure is progressive die punching press, what adopt is six engineering impact styles, carry out the bending of surrounding in the 5th step, and mould used as shown in Figure 3,4, on counterdie 2, have two slide blocks that can move inward 3, after patrix 1 pressed down closure, by the slipper push device, two slide blocks 3 moved inward, flat product is made to the U-shaped bending, then at opening (also referred to as the opening) otch of the 6th stepping interline, even if complete, obviously middle opening does not have the deburring means.
And the present invention is optimized whole product step, redesigned the distribution of six engineerings, directly complete the deburring to middle opening opening.
, designed as Fig. 5,6 flanging mould, described mould has patrix 1 and counterdie 2 for this reason, and wherein patrix 1 is provided with a slide block 3 and push rod 4, and counterdie 2 is provided with Bending punch 5, and the position of Bending punch 5 is positioned at horizontal dead-centre position one side of slide block 3; Push rod 4 and slide block 3 have interlock.On transverse slider, have a slim sheet projection 6, be used for to the shaping of bending part from L shaped to U-shaped.
Concrete punch steps is:
