Abstract
The present invention relates to a manufacturing method for a frame of a cathode ray tube, which comprises the following steps that a blank are blanked, a connecting part on the blank is reserved simultaneously, and a transmissive area of the blank is punched to form a positioning hole; the blanking part is punched into a hole in a shape of a TV or a monitor fluorescent screen; the edge of the part in a shape of a monitor fluorescent screen is shaped after bent inwards; the part shaped in a calendering mode is molded into a frame, and the connecting part is cut off. The steps are sequentially completed on one punching machine.
Description
Invention field
The present invention relates to be used for the manufacture method and the equipment of the framework of cathode ray tube, particularly on a punch press, finish the method for framework manufacturing step simultaneously.
Background technology
Usually, adopt framework to settle the cathode ray tube that is used for display image on TV or the monitor panel.Be the image of clear display on phosphor screen, answer the fit tolerance between strict control framework and the cathode ray tube.Therefore, the pinpoint accuracy in the framework manufacturing technology is considered to very important.
Use the framework manufacturing process of metallic plate to generally comprise the following step: the calendering workpiece is molded as predetermined shape; To the calendering part punching of workpiece, so that form the hole of reservation shape thereon; Shaping frame makes it have the reservation shape that does not comprise punching; With last finishing frame edge.
, above-mentioned process has such problem, promptly this can adopt carry out continuously a progressive method in steps, make material unaccounted-for (MUF) so big but occur in the scrap that finishing produces in handling.Especially, in the bigger product, material unaccounted-for (MUF) is sizable as the TV framework.
In order to reduce material unaccounted-for (MUF), the framework manufacture method of blanking, calendering, punching and forming step is carried out in use in proper order.
But though can reduce material unaccounted-for (MUF) with this method, owing to separate with the redundance of workpiece through the blanking part of first step blanking step, so institute just can not carry out in steps progressively, therefore the step of following is just separately carried out.
That is to say, carry out progressively this method in steps the problem of material unaccounted-for (MUF) is arranged, but not this method of carrying out progressively has step complicated and that separately implement.
Summary of the invention
The present invention just relates to the manufacture method of the framework that is used for cathode ray tube, and this method has overcome substantially owing to there are one or more problems in the restriction of prior art and defective.
The manufacture method that the purpose of this invention is to provide the framework that is used for cathode ray tube, in this method carry out progressively in steps, simultaneously can reduce material unaccounted-for (MUF).
In order to realize these and other advantage of the present invention, the invention provides a kind of manufacture method that is used for frame for cathode ray tube, comprise the following steps: the blank blanking is kept the tie point on it simultaneously, but the transit area of punching out blank forms location hole; To the punching of blanking part, form the hole of TV or display monitor central monitoring system phosphor screen shape; Make by the edge of the part of punching and be shaped with bending inwards; Part with calendaring molding is molded as framework, cuts off tie point simultaneously, and wherein these steps are sequentially carried out on a punch press.
The present invention provides a kind of equipment that is used to make frame for cathode ray tube on the other hand, this equipment is provided with punch anchor clamps and a die holder, wherein, described punch anchor clamps and die holder are arranged to following each several part in regular turn: (1) blanking die part, be used for that the blank blanking become the shape of cathode ray tube and keep tie point on it, this blanking die comprises a location hole punch-out, is used for forming in the transmitted district of blank location hole; (2) perforating die part is used for forming the hole with TV or monitoring phosphor screen shape at the zone line of blanking part; (3) finishing die part is used for the edge of punching part is bent inwards; And (4) calendering mould part, the blank that is used for being shaped is molded into framework and cuts tie point.
To show supplementary features of the present invention and advantage in the explanation hereinafter, this can understand from explanation, or understand by enforcement of the present invention.By the structure that the explanation in the literary composition and claims and accompanying drawing particularly point out, will realize and obtain purpose of the present invention and other advantage.
Should be appreciated that above-mentioned general description and following detailed description all are to show row and illustrative, desire is to the further explanation that the invention provides that claim limited.
Brief description of drawings
Accompanying drawing constitutes the part of this specification, shows embodiments of the invention, accompanying drawings, and it illustrates principle of the present invention, provides further understanding of the present invention.Wherein:
Fig. 1 and 2 is the profile of the punch press of the preferred embodiment of the present invention, and order is equipped with blanking, punching, shaping and calendering mould in the punch press; With
Fig. 3 is a plane graph of showing mould pressing process process of the present invention.
Detailed description of the preferred embodiment
Now will be in conjunction with the accompanying drawings, describe the preferred embodiments of the present invention in detail.
Fig. 1 is before this method is carried out, and when the backform of punch press and bed die are separated from each other, are mounted with blanking, punching, shaping and calendering mould in regular turn and have inserted the cross section view of sheet material blank.
Fig. 2 is punch press backform and the contacted cross section view of bed die.
Fig. 3 is that expression moves up and down according to punch press and to make blank be molded into the plan view of framework process with mould.
As illustrated in fig. 1 and 2, blanking die 2, perforating die 4, finishing die 6 and calendering mould 10 are installed in regular turn between the punch anchor clamps 1 of punch press and die holder 23.When being separated from each other, backform and bed die insert blank.When backform and bed die are meshing with each other, utilize stamping press to finish blanking, punching, shaping and calendering step simultaneously.
In the blanking step, in the transmitted district of blank, form location hole, with its transmission be fixed on the tram of adjacent molds.Simultaneously, the blank blanking becomes the shape of cathode ray tube, and keeps tie point thereon, prevents that the blanking part is separated with blank.This tie point can carry out all steps progressively.
In the punching step, form hole at the zone line of blanking part with TV or monitoring phosphor screen shape by punching out.
In the forming step, the edge of punching part bends inwards, and certain angle slightly tilts.
At last, in the calendering step, shaped portion is molded into framework, cuts tie point simultaneously.
Owing to blank is rigidly fixed in each mould with alignment pin, prevented to rock, therefore can obtain high-quality framework through above each step.
In punching operation, implementation framework manufacturing step sequentially.Therefore, when each step finished, the workman will not send into adjacent mould by blank.This not only provides convenience, and can produce in batches on the basis of improving work efficiency.
As mentioned above, framework manufacture method of the present invention is to implement progressively.That is to say, sequentially carry out blanking, punching, shaping and stretching step with this method.Thereby no matter purpose how, this method can be widely used, and can obtain high-quality framework.
Obviously, those skilled in the art can carry out various qualifications and modification to the method that manufacturing of the present invention is used for frame for cathode ray tube, but this can not break away from the spirit and scope of the invention.That is, the present invention will by the various modifications of being carried out in claim and its equivalent scope and limit cover.
