Abstract

The utility model provides a one-die multipurpose punching and flanging tool for machining a sheet materials of shielding cases with multiple specifications, and the tool comprises upper and lower dies which are used for molding the shielding case. The upper and lower dies are provided with a plurality of universal fixed positioning pins and a plurality of reserved positioning pin holes. The lower die is provided with a plurality of elastic convex blocks which are respectively provided with a punching nail in an embedded manner, wherein the punching nails are used for machining through-hole flanges. The upper die is provided with slotted holes which cooperate with the punching nails and are used for molding a turning plate. Two sides of each slotted hole are respectively provided with an elastic convex pin which abuts against the corresponding convex blocks. The dies employed by the tool can be suitable for the punching and flanging of the shielding cases with multiple specifications, thereby greatly reducing the manufacture cost of the dies, and improving the work efficiency.

Description

Many specifications of one module multiple usages radome machining sheet piercing and flanging processing mold

Technical field

The utility model relates to a kind of many specifications of one module multiple usages radome machining sheet punching turnover panel processing mold.

Background technology

?as Fig. 1~2 are depicted as the shielding case structure of liquid crystal display, in forming process, need panel beating to carry out punching bending, forming riveting post by piercing and flanging, pass through afterwards riveting molding, because the radome size of the display of different size also difference is therefore in the time carrying out piercing and flanging operation, need to manufacture multipair mould and manufacture, cost is very high, and efficiency of assembling is low.

Summary of the invention

The utility model improves the problems referred to above, and the technical problems to be solved in the utility model is the radome that existing radome piercing and flanging mould is only suitable for a kind of specification, and cost is very high, and efficiency of assembling is low.

Specific embodiments of the present utility model is: a kind of many specifications of one module multiple usages radome machining sheet punching turnover panel processing mold, comprise the upper and lower mould for moulding radome, described counterdie is provided with several general fixed locating studs and several reserved dowel holes, described counterdie is provided with several elastic projections, described elastic projection is embedded with the punch for processing through hole flange, described patrix has and matches with punch for the slotted eye of moulding turnover panel, and described slotted eye both sides are provided with the elasticity protruding pin of supporting elastic projection.

Further, described counterdie comprises counterdie seat board and is fixed on the counterdie fixed head on counterdie seat board, described counterdie fixed head bottom is provided with a groove, described elastic projection is embedded in groove, groove middle part is provided with the through hole stretching out for elastic projection, described elastic projection lower end is provided with annular seating, elastic projection lower end is connected by spring with counterdie seat board, make annular seating upper surface be resisted against counterdie fixed head through hole perimembranous, described punch is fixedly connected on counterdie seat board, and punch stretches in the punch through hole of elastic projection middle part setting through elastic projection bottom.

Further, described patrix comprises upper clamping plate and upper mould fixed plate, and described slotted eye is arranged on upper mould fixed plate, and described elasticity protruding pin is embedded in upper mould fixed plate, and described upper surface is connected with upper clamping plate by spring.

Further, described punch upper end is taper.

Further, described counterdie is also provided with elastic projection preformed hole and punch preformed hole, in described elastic projection preformed hole, is provided with and inserts.

Compared with prior art, the utlity model has following beneficial effect: the mould that the utility model adopts carries out the operation of piercing and flanging applicable to the radome of different size, greatly reduce the manufacturing cost of mould, improved operating efficiency.In the design of piercing and flanging mould, the utility model adopts cooperatively interacting of elastic projection and elasticity protruding pin, has both realized the buffering of die punching flange, is also convenient to the demoulding.
