Problems solved by technology

Although the extrusion block uses a spring as the first elastic element to provide it with stable performance, the elastic element tends to lose its elasticity after long-term use, so that the stamped product is inaccurate, the product quality is poor, and it needs to be replaced many times

Abstract

The invention discloses an LED display backplane groove dressing die. The LED display backplane groove dressing die comprises an upper die base (21) and a dressing adjusting part (3) arranged under the upper die base (21); the dressing adjusting part (3) comprises an adjusting lead screw (31), an oblique die (32) and an adjusting punch (33); the adjusting lead screw (31) is transversely arranged on the lower end face of the upper die base (21) by use of a lead screw fixed block (34); the adjusting punch (33) is perpendicular to the adjusting lead screw (31); the oblique die (32) is arranged at the end portion of the adjusting lead screw (31) by use of a ball roller (35); the left end of the ball roller (35) is fixedly connected with the end portion of the adjusting lead screw (31); the right end of the ball roller (35) is arranged in the oblique die (32) and capable of rotating relatively to the oblique die (32). The adjusting lead screw directly provides acting force to the oblique die in a linear manner and then the oblique die controls the adjusting punch to move; the LED display backplane groove dressing die has the advantages of stable force transfer and accurate oblique die motion.

Description

technical field [0001] The invention relates to the technical field of mold structures, in particular to a mold for shaping grooves on a backplane of an LED display. Background technique [0002] LED display (or LCD display) is a flat panel display device. In the structure of LED (or LCD display) display, the shell is tightly wrapped around the core LED (LCD) display components (PCB PANEL printed circuit board, SHEET reflective foil, etc. ) important parts. Since the LED (LCD) display panel itself does not emit light, it is necessary to install a lamp behind it to emit light, so the back panel not only plays the role of fixing the LED (LCD) display component, but also needs to provide reflection for the lamp installed in the groove. In order to improve the lighting effect of the lamp tube. It is generally used to fix the backplane of the LCD panel. It uses metal frame parts and connects the external shell. It can be said to be the "skeleton" of the LCD display. There are h...
