Abstract
The present invention relates to the Production of Stamping Die technology of the important feature parts backboard of a kind of curved surface TV set LCD, and feature is first in the first project curved surface molding, after the such as trimming of other techniques, convex closure shaping, snap fit molding, hole punching press, marking, dabbing stings, little bending, marking, sprout and all-round bending etc. is all carried out on curved surface, and curved surface is by sheet metal component being drawn into bottom for the box-like body of curved surface in the first engineering, then excises clout and form；During curved surface stretching, mould is provided with stretching beading, favourable stretching and curve stable.
Description
Technical field
The present invention relates to the Production of Stamping Die technology of important feature parts (BOT CHASSIS) backboard of a kind of curved surface TV set LCD.
Background technology
(OLED BOT CHASSIS) curved surface backboard is used to install curved surface liquid crystal panel and circuit board important feature parts.Curved surface backboard is similar relative to the structure of flat back plate, surrounding has the forming surface of bending edges, hole, many location, projection, recessed, chamfering, variously-shaped fluctuating, snap fit is had on backboard, the structure such as sprout, difference be the most all process structures of curved surface backboard be to complete on curved surface, production difficulty is bigger.
Existing mould production method: method 1: produce by first general closed planar backboard method, on the basis of each technique of flat back plate completes (including all-round bending), increase by a curved surface shaping process, reaches backboard bending purpose；Method 2: before last bending molding process, produce by general closed planar backboard method, and complete curved surface technique while bending molding process.
The above two schemes technological deficiency is: hole, location, projection, recessed, chamfering, snap fit, the technique such as sprout are first to complete on datum plane, and after curved surface forming, the relative position of these technique shapes changes, size generation relatively large deviation.Product quality is unstable, increases assembly difficulty.
Summary of the invention
In order to overcome the defect of prior art, the present invention provides a kind of new curved surface backboard mould production technology.
The mould manufacturing method of the present invention is: 1. first go out what bottom was cambered surface casing extrusion at the first engineering tensile.
2. preferred, radian and the convex closure of the cambered surface of box bottom are completely the same with the radian of product and convex closure, the size big 5MM more monolateral than the development size of product of stretching casing cambered surface.
3. other techniques such as trimming below, convex closure shaping, snap fit molding, hole punching press, marking, dabbing stings, little bending, marking, sprout and all-round bending etc. is all carried out on the basis of cambered surface, and the upper die and lower die surface configuration of diel is arc, consistent with the radian of stretching casing cambered surface.
After using technical solution of the present invention: Curved LCD backboard stable molding is reliable, hole, location on backboard, projection, recessed, chamfering, variously-shaped fluctuating, snap fit, the labyrinth position dimension such as sprout is the most errorless, follow-up with in miscellaneous part assembling process, smooth and easy fast.
Accompanying drawing explanation
Fig. 1, Curved LCD backboard product figure
Fig. 2, casing tensioning member
Fig. 3, the stamping process program of invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the mode of the present invention is further elaborated:
Shown in Fig. 3, according to described scheme of the invention, 6 molds made according to new scheme are separately mounted to installation and debugging on 6 stamping machines and put in place.
The substantially division of labor is such that
By feeder, coiled strip being entered No. 1 stamping machine, all-round being provided with in beading (Fig. 2) 1 pushes down material embryo, and stretched bottom is the casing of cambered surface 2, and the convex closure in cambered surface stretches the most together simultaneously.
By mechanical arm, semi-finished product taking-up in No. 1 stamping machine is transferred to No. 2 stamping machines, to product design blank, convex closure shaping in cambered surface, snap fit molding.
By mechanical arm, semi-finished product taking-up in No. 2 stamping machines is transferred to No. 3 stamping machines, product design remainder blank, aperture punching press in cambered surface, marks, locally-shaped etc..
By mechanical arm, semi-finished product taking-up in No. 3 stamping machines being transferred to No. 4 stamping machines, product section dabbing stings, little bending, marking, locally-shaped.
By mechanical arm, semi-finished product taking-up in No. 4 stamping machines being transferred to No. 5 stamping machines, the whole dabbing of product remainder stings, and aperture dabbing stings, and sprouts.
By mechanical arm, semi-finished product taking-up in No. 5 stamping machines being transferred to No. 6 stamping machines, all-round bending adds part cambered surface shaping, and punching press completes.
Claims (4)
1., for a punching production method for Curved LCD backboard, product first stretched bottom is the casing of arc, is carrying out follow-up trimming, convex closure shaping, punching, and all-round dabbing stings, all-round bent reshaping.
2. it is characterized in that: product ready-made radian molding, follow-up various forming action complete on the basis of big cambered surface molding.
Manufacture method the most according to claim 1, is characterized in that: radian and the product radian of stretched cambered surface are completely the same, and cambered surface overall dimensions is monolateral big 5MM than product development size.
Manufacture method the most according to claim 1, is characterized in that: technique such as punching, projection after casing stretching, marking, dabbing are stung, snap fit, and sprout and all-round bending etc. is to carry out on the basis of cambered surface and upper and lower mould surface configuration is consistent with product arc shape.
