Abstract
The invention discloses a producing method for stamping a liquid crystal display shielding case from a thin plate and reducing distortion. The producing method comprises the following steps of stamping a substrate, stamping a mounting convex face, stamping holes, stamping folding frame edges and restoring height. In the step of stamping the mounting convex face, the height of the mounting convex face is stamped to be 1.3h-1.5h, and the rigidity of the substrate of the shielding case is made to be improved. Therefore, in the subsequent steps of stamping the heat radiating holes and stamping the folding frame edges, the distortion of the substrate of the shielding case can be reduced to the maximum extent. Finally, the height of the mounting convex face returns to be h in a stamping mode. The whole producing process is simple, and the distortion of the substrate of the shielding case can be effectively reduced.
Description
Technical field
The present invention relates to and become liquid crystal display radome to reduce the production method of distortion with sheet stamping.
Background technology
Available liquid crystal display radome is all generally adopt thickness to be that the substrate of 0.8mm is made, and the method manufacturing radome generally comprises following steps: the installation convex surface 1, at substrate upper punch delivery lift being h; 2, on substrate punching press louvre, 3, stamp out folding edge at the side of substrate.Install convex surface and mainly contain two functions, one function is be fixed on the mainboard of liquid crystal display by radome, and another function is the rigidity increasing substrate, improves the anti-twisting property of substrate.
Now, a lot of producer is in order to save cost, take to replace thickness to be originally the substrate of 0.8mm with thinner substrate, but adopt thinner substrate, thin substrate is being stamped out after highly for the installation convex surface of h, thin substrate is rolled in the step of edge at follow-up punching press louvre and punching press, and because the rigidity of thin substrate is inadequate, finally shaping radome distortion is serious.
Summary of the invention
A kind of production process is the object of the present invention is to provide simply to become liquid crystal display radome to reduce the production method of distortion with sheet stamping.
For achieving the above object, the present invention adopts following technical scheme:
Become liquid crystal display radome to reduce the production method of distortion with sheet stamping, described production method comprises rushes substrate, and convex surface is installed in punching, and punching, washes off edge, returns high five steps, and the installation convex surface height that convex surface step is installed in described punching is h; Described production method is specially:
1), substrate is rushed: be that the sheet metal of 0.4mm is placed in punch press by thickness, stamping-out goes out radome substrate;
2), convex surface is installed in punching: the radome substrate obtained in step 1) is placed on punching and installs in the punch press of convex surface, and be the installation convex surface of 1.3h ~ 1.5h at radome substrate upper punch delivery lift;
3), punching: by step 2) in the radome substrate that obtains be placed in the punch press of punching, and stamp out louvre on radome substrate;
4), edge is washed off: be placed on by the radome substrate obtained in step 3) and wash off in the punch press of edge, and edge is washed off to the side of radome substrate;
5), Hui Gao: the radome substrate obtained in step 4) is placed in another punch press, and reverse punching press is carried out to the installation convex surface of radome substrate, make the height installing convex surface get back to h.
The present invention adopts above technical scheme, install in the step of convex surface in punching, first the height punching press of convex surface will be installed to 1.3h ~ 1.5h, the rigidity of radome substrate is increased, therefore, rolls in the step of edge at follow-up punching press louvre and punching press, the distortion of radome substrate can be reduced substantially, finally will install the height refunds of convex surface to h, whole production process is simple, but effectively can reduce the distortion of radome substrate.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further detailed explanation:
Become liquid crystal display radome to reduce the production method of distortion with sheet stamping, described production method comprises rushes substrate, and convex surface is installed in punching, and punching, washes off edge, returns high five steps, and the installation convex surface height that convex surface step is installed in described punching is h; Described production method is specially:
1), substrate is rushed: be that the sheet metal of 0.4mm is placed in punch press by thickness, stamping-out goes out radome substrate;
2), convex surface is installed in punching: the radome substrate obtained in step 1) is placed on punching and installs in the punch press of convex surface, and be the installation convex surface of 1.3h ~ 1.5h at radome substrate upper punch delivery lift;
3), punching: by step 2) in the radome substrate that obtains be placed in the punch press of punching, and stamp out louvre on radome substrate;
4), edge is washed off: be placed on by the radome substrate obtained in step 3) and wash off in the punch press of edge, and edge is washed off to the side of radome substrate;
5), Hui Gao: the radome substrate obtained in step 4) is placed in another punch press, and reverse punching press is carried out to the installation convex surface of radome substrate, make the height installing convex surface get back to h.
