Description
Technical field
The invention relates to automatically and accurately processing substantially the low dip face of vertical direction method and use the guiding mechanism of the mould of this processing method.
Background technology
During to the metallic plate pressure processing, usually under the state that the shape of the patrix of mould and counterdie is harmonious,, need certain clearance between upper and lower mould, leaving the space that can correctly guarantee hickness of metal plate.In addition, in the occasion of metallic plate plastic deformation, shape becomes the part of acute angle or in when distortion and easy confined shape part easily forms CREASE MARK, cracky or easily produces askew phenomenon can betide pressure the time.
In order to prevent this phenomenon, in the scope that can keep shape, be necessary specially to be provided with the effusion gap, or carry out fillet and handle.Thereby the gap affects of the patrix of mould and counterdie is to the state of the last processing of goods, so be epochmaking factor.
Therefore, when the patrix that makes mould and counterdie relatively move, correctly lead quite important.Guider usually uses by the guider that pin and guide hole constituted, or the guider that is made of the planar guide face.
Wherein, be used for more small-sized and effortless pressure processing by the guider that pin and guide hole constituted.
The guider that is made of the planar guide face then is used for pressure processing large-scale and effort, and most of this structure that adopts of pressing mold.
As shown in Figure 9, normally to be integrally formed at the framework that is equipped with as the mould (die) of the counterdie of mould be on the retaining member to this planar guide face.Perhaps shown in Figure 13, be integrally formed on the die ontology.Thereby directly guiding as the punch press of the patrix of mould, or guiding blank (blank) retaining member.
Mould and generally be that the casting system forms as the mould retaining member of framework, its size arrives 1-10m greatly, and complex-shaped.As shown in Figure 9, the spigot surface that forms the mould retaining member is not only whole relatively mould retaining member face toward the outer side, and many situations towards the inboard are also arranged.In addition, some position is very narrow, thereby the processing of spigot surface is quite difficult.The situation of die ontology is also identical.Machining center (machining center) is adopted in the processing in these places usually.Yet be installed on machining center main tapping standard fitting usually because and produce to interfere between framework or with die ontology (shown in Figure 13), thereby can't process.Therefore, need sometimes to make special accessory, yet it is still quite difficult to process whole spigot surfaces.
So, be elongated slotting cutter (end mill) to be installed on the main shaft of machining center process in the past, but adding man-hour, the blade part of slotting cutter almost is to apply cutting force in the process by total length, so can't finish the procedure of processing that needs slotting cutter to break away from working substance and carry out.
In addition, the height that is caused because of the helical pitch (lead) of the vibration of the blade of slotting cutter and blade rises and falls and conducts to machined surface, and then can not process smooth plane.Therefore after processing, need this machined surface of finishing.Perhaps stick slide plate, to be used as spigot surface.In order to carry out correct dimensional accuracy correction, on slide plate, carry out machining, and then revise the out-of-flatness of the machined surface that slotting cutter processing caused, to guarantee the gap with the upper mould sliding surface of offside.
But, when repeating thousands of workpiece of pressure processing, because the sliding surface abrasion of slide plate need detect during certain, and repair.Because framework is very big, and weight is also heavy, so expend time in very much and the labour when finishing.In addition, owing to slide plate carried out correction such as machining,, also must repair again taking off when assembling again so the patrix of finishing back mould cooperates with the mould of counterdie and is difficult to reproduction.
In order to eliminate the above-mentioned shortcoming that is caused by elongated slotting cutter processing, the someone adopts slotting (plunging) instrument as shown in figure 14 to carry out slotting processing recently.But, disclose shown in the flat 5-92347 communique as Japan Patent, in the past, added man-hour carrying out this slotting, need final relatively workpiece (work) of design that a secondary operations outline line b who equals the off normal of allowance t be arranged.And secondary operations outline line b calculates time processing outline line d thus.And try to achieve the middle cardioid c of the off normal of tool radius in addition by secondary operations outline line b.Then, obtain each the Along ent distance that departs from the above-mentioned time processing outline line d and be each processing stand C11, C12, C13 on the middle heart shape line c of tool radius R ...Come work package is carried out slotting processing with these each processing stands.Thereby the program that need carry out many computings to each machined surface.
Guiding has slotting processing with the processing method of machined surface is known, but must carry out many computings for each machined surface, and causes the problem that each tool path must be given sequencing.
The described spigot surface structure of known technology is only installed slide plate for guiding with machined surface, and causes the machining accuracy difference of machined surface itself and the essential problem that repair.And owing to be convenient to needs finishing that wearing and tearing that slide plate causes bring or the problem of upgrading.
