CN2548779Y - Die seat for PC board puncher - Google Patents

Abstract

The utility model relates to a PC plate inner layer puncher die holder. The structure is modified in that the puncher die holder is improved as a fixed type, therefore the punches which are needed by the whole material sizes are arranged in the hole distance template of the upper die holder; the lower die holder is a whole tablet to embed the punching lower die rings of different material sizes; when one material size is produced, the punches which are used for the PC plate punching are pushed or replaced by the upper die plate with manually operation or automatic operation to improve the precision and the repeatability, which makes the flexible scheduling of the working more flexible.

Description

PC inner cord perforating press die holder

Technical field

The utility model relates to a kind of plate perforating press mould, refers to a kind of PC inner cord perforating press mould especially.

Technical background

Each inner plating of general printed circuit board (PCB) (PC plate) usually as shown in Figure 1, needs earlier on PC plate 1 punching out rivet hole and for the locating hole 11 (general distribution situation is more general with 8 holes) of successive process use in processing procedure.Rivet again and the pressing operation.

Because the live width and the line-spacing of PC plate 1 are more and more little, so also relative being required of the precision of each inner plating riveted joint improves; In putting before this, directly connection be punching precision and the heavy property covered need quite high, with present processing procedure; The precision of punching is in 0.001 inch of scholar, and heavily the property covered more need reach 0.0005 inch of scholar, so; All more traditional punch press of the precision of perforating press itself and mould and mould have great difference.

Existing P C plate 1 has various size dimension, and the size of passing through in the market is all common from 12 inches to 28 inches, and its inner plating has different designs with the difference of work size certainly on rivet hole and locating hole 11; Making for ease of facility and mould, punching operation in the inner plating has its set form layout, roughly on the PC of close ordering plate 1, the punching pitch-row is done one with per 0.5 inch and is separated (as shown in Figure 2, wherein C represents the size that immobilizes, and XA, XB, YA and YB are then different with the item number size).

And for the PC plate 1 of various different size item numbers, can be in carrying out the punching operation after its pitch-row specification of conversion fast on same the perforating press, therefore, shown in Fig. 3,4, the perforating press 2 that is sold on the market, the structure of the upper and lower mould 21,22 of the activity of promptly being made as at aforesaid demand is though it can change pitch-row rapidly, with the production demand in response to different item number sizes, but there is following shortcoming at least in it:

1. movable upper and lower die holder 21,22 is provided with PC inner cord perforating press die holder 23 and inserts location (referring to Fig. 5, Fig. 6) after switching the item number size on the dowel hole template 24, die holder left and right sides and below are provided with guide block 25 and tray 26, the mismatch error that the alignment pin 23 of the die holder up and down 21,22 of this structure and alignment pin template are 24, and the mismatch error of 26 on upper and lower die holder 21,22 itself and left and right sides guide block 25 and below tray.Owing to have seven kinds of assemblies, the kind of its interactional error reaches 14; Die holder 21 up and down, the 22 error sums that produced because of the cooperation factor then are 28, so many error accumulation and interactional result, promptly cause the punching precision can't reach requirement below 0.001 inch, therefore, expedient method lies in a collection of inner plating and needs punching on same perforating press, operation under the heavy still acceptable situation of the property covered, the side is unlikely the serious deviation of appearance on the follow-up riveted program, based on aforesaid various states, make the scheduling elasticity of facility be on duty mutually, factory thereby be forced to purchase a large amount of lathes is with the product production of reaching the standard grade simultaneously in response to different item numbers every day.

2. when movable die holder is changed pitch-row, need alignment pin 23 is extracted, make that die holder 21,22 (totally ten six) all need be done this pull action up and down, though establishing a hand-held tool, commercially available board die holder 21,22 up and down can be extracted alignment pin 23 simultaneously, push to another position, hole more simultaneously, only this instrument is not easy to operate; Especially for the less women operating personnel of strength, promote this die holder 21,22 and being not easy up and down simultaneously; Therefore, most operating personnel are all with this up and down conversion of die holder 21,22 of free-hand operation, when not only consuming expenses of labour, and narrow and small because of the space, the visual field is not good, makes die holder push the position and goes wrong.

3. existing perforating press 2 is to adopt the punching cylinder 21 of four device board belows for driving upper bolster 21 downward punchings, because four oil hydraulic cylinders 27 can't reach synchronous, directly influence the precision of punching, and under the guide pillar and the unbalanced active force of steel ball lining for die holder 21,22 up and down, easy attrition, life-span is shortened, cause the puzzlement of maintenance work.

Summary of the invention

Therefore, main purpose of the present utility model is promptly providing a kind of PC inner cord perforating press die holder, significantly promotes PC plate punching precision and the heavy property covered with the improvement of its structure, and makes the flexible scheduling of operation more flexible; Increase production capacity efficient and parts service life.

The purpose of this utility model is achieved in that

A kind of PC inner cord perforating press die holder is characterized in that including:

Upper bolster is to be provided with spacer holes apart from template, and the punch device that makes whole item numbers is provided with an excellent power glue material returned bar in this pitch-row template bottom in this pitch-row template; Can be manually or automated manner the drift self-template is released;

Die shoe is a full slice system, embeds for modular ring under the punching of different item numbers;

One oil hydraulic cylinder is to be located at the perforating press top center, for being connected in a flexible connector, constitutes this upper bolster single thrust vertically downward.

Good effect of the present utility model is:

Because aforesaid die holder structure, be die holder to be made as fixed, make the required punch device of whole item numbers in the pitch-row template of upper bolster; Die shoe then is made as full slice system, and for modular ring bank people under the punching of different item numbers, part is able to manually or automated manner when producing a certain size item number, and required drift is released or changed by cope match-plate pattern.

Because the drift of upper bolster can directly stretch out operation by template, this die shoe is exempted up and down issuable various errors owing to be full slice system, can significantly promote punching precision and the heavy property covered, and help the interchangeability of different item number batch jobs, be beneficial to flexible scheduling.

Because aforesaid die holder structure, lie in up and down and establish with an independent oil hydraulic cylinder above the die holder, via a flexible connector, oil hydraulic cylinder is led people central authorities single thrust vertically downward fully, finish punching under the guiding via four limit guide pillars and the equilibrium of steel ball lining again, can improve the service life of precision and increase assembly.
