Problems solved by technology

[0004] Therefore, energy-saving lamp tubes emerge as the times require. For the U-shaped lampshade on the energy-saving lamp tube, the molds in the prior art can only adopt the segmented L-shaped bending process, which requires at least two working steps to be stamped. The auxiliary time required in the process is long, the production efficiency is low, and the size is inconvenient to control, so that the qualified rate of the lampshade is low

Abstract

The invention discloses a none-step forming die for lampshades. The one-step forming die comprises an upper die and a lower die, the upper die comprises an upper clamping plate, a stripping plate, an upper pressure block and a punch; and the lower die comprises a lower clamping plate, a lower stopper, a drive block, a positioning block, an inner strip block, a first ejector pin, a second ejector pin, tie screws, equal-height sleeves and springs. The upper pressure block capable of sliding in the stripping plate drives the punch to press a lampshade into the slider, the slider is pushed by spring force from the springs on the tie screws so as to press the outer surface of the lampshade, and finally the lampshade is formed at one step finally. Accordingly, assisting time is saved, process stations are reduced, labor intensity of technical staff is reduced, labor is saved, equipment resources are saved, production efficiency and qualified rate are increased remarkably, the one-step forming die for lampshades is convenient to use, and is subjected to one-stop control convenient for adjustment and maintenance.

Description

technical field [0001] The invention relates to the field of stamping production, in particular to a disposable molding die for a lampshade. Background technique [0002] The lampshade is a piece of hardware that covers the lamp to gather the light together. It can also prevent electric shock and protect the eyes. Therefore, most lamps are equipped with a lampshade. [0003] With the continuous progress of society and the continuous development of science and technology, people are now more and more concerned about how to improve the environment and reduce pollution. Among them, the most important and urgent problem is the energy problem. In order to solve the energy problem fundamentally, besides finding new energy sources, energy saving is the most critical and the most direct and effective measure at present. [0004] Therefore, energy-saving lamp tubes emerge as the times require. For the U-shaped lampshade on the energy-saving lamp tube, the molds in the prior art can ...
