Abstract
The invention relates to the manufacturing process of metal bottom film plate for paper carton mold cutting. It uses stainless iron or other spring steel plate, trimming it, installing magnetic sucker on the lathe with a metal cushion on the surface of the sucker, closing the magnetic sucker after the parts on the metal cushion being processed. The processing comprises of cutting slots on the metal bottom film plate using plain cutter, grinding the shape using tapering knife, drilling positioning hole on the metal bottom film, cutting off the shape of the metal bottom film using tapering knife, taking off the product using the sucker. It only needs one time input for long assembly production, free from more bottom mold with greatly reduced spare parts. Since the bottom mold can be shoveled repetitively with high hardness of the inner wall of the bottom mold, durability over 50, 000, 000 times, greatly reduced in cost.
Description
Technical field
The invention belongs to the manufacture craft of the bottom diaphragm of in the cross cutting processing of paper package box, using.
Background technology
Bed die claims former again, is widely used in the cross cutting processing of paper package box.Its effect is to cooperate with bed die with indentation line to make the paper that is stamped form folding line so that it is converted into box.Bed die following several technologies commonly used are made at present.
Manual field fabrication papery bed die: on the press backing plate, be stained with the paper that one deck is prepared for doing bed die.Load onto the die cutting plate punching press once, the trace seal after obtaining the indentation line coining on the paper; On paper, draw the bed die wire casing with hand-held knife and ruler and make the paper bed die.The method of bed die is manufactured in this craft, and bed die groove glacing flatness is poor, and groove width control is bad, and the papery bed die life-span is low, is disposable use.
Plastics bed die bar (being called for short the bed die bar) manufacture craft: by die cut operation worker length severing bed die bar as required, the guiding plastics are pressed on the indentation line, after opening a press punching press of double faced adhesive tape strippable paper, the bed die bar just is bonded on the cross cutting backing plate, and the guiding of taking away plastics are finished bed die and installed.This type of bed die bar is generally with plastics or mould the paper composite material and make, about 500,000 times of life-span.A box will have 7,8 or tens indentation lines installations in length and breadth, and technology is cumbersome, must keep the cross cutting backing plate in the time of using several times and not do its usefulness.The general disposable use of bed die bar is just scrapped down from cross cutting backing plate shovel.
Epoxy resin bed die sheet (being called for short the resin bed die): the supporting resin bed die of manufacturing when doing the cross cutting knife plate.Manufacture craft is generally to open the bed die wire casing and cut into the bed die sheet with the computer engraving machine.Be characterized in the corresponding resin bed die of a box.In knife plate and bed die, leave corresponding locating hole, the resin bed die is installed with alignment pin.About 1,500,000 times of life-span.Its shortcoming is that the cross cutting backing plate can not be used for other products when using several times.The resin bed die is bonding with double faced adhesive tape or adhesive and cross cutting backing plate.Because the bottom thickness of groove is only about 0.1mm, in case shovel down, must damage.And about 1,500,000 times of life-span, still belong to disposable products.
In sum, the distinct disadvantage of these manufacture crafts and products thereof is that the life-span is short, can not shovel down repeatedly repeatedly and install.Especially improper for some cigarette cases, soapbox, oversupplied goods that toothpaste box equivalent is big.But because present situation is that these oversupplied goods are ordered the resin bed die in a large number repeatedly, cost is very high, and the quality of bed die impression seal can progressively descend unstable product quality with the wearing and tearing of wire casing inwall.
Summary of the invention
The objective of the invention is,, provide a kind of manufacture craft of using the metal bottom diaphragm of metal material instead of resins material for overcoming the shortcoming that above-mentioned prior art exists.Its process is as follows:
1) adopts stainless iron or other spring steel sheet material;
2) sheet material smooth back cutting;
3) on lathe, install magnetic chuck, put a metal caul in chuck surface again;
4) after putting work piece on the metallic plate, the switch of the magnetic chuck that closes;
5) process:
The first step is with the plain cutter groove that bursts at the seams on metal bottom diaphragm; Wire casing partly is the main functional parts of bed die, and promptly cooperate aborning punching press paper forms the folding line seal with the formpiston indentation line;
Second step is with boring cutter polishing metal bottom diaphragm profile;
The 3rd step was bored locating hole with plain cutter on metal bottom diaphragm; The effect of metal bottom diaphragm locating hole is that when using metal bottom diaphragm, its locating hole cooperates with the locating hole of die cutting plate (formpiston), with alignment pin relative position between the lock female formpiston when installing and using.
The 4th step all cut off with the profile of awl hilt metal bottom diaphragm,
5) open the magnetic chuck switch after the completion of processing, take off finished product and promptly finish technical process.
In above-mentioned process, in the described first step, groove depth is more than or equal to the thickness of processed paper, groove width equal 1.5～2 * paper thick+the impression live width; Cutter 1 is a plain cutter; Processing feed speed 450～600mm/ minute, the each 0.1～0.15mm of plain cutter fluting feeding depth, the angle of awl cutter is 155 °～160 ° in described second step; Its effect is to form acute angle at the bed die product edge of the overwhelming majority, and the main effect of acute angle is that processed paper is not moved above bed die by bigger resistance can when bed die uses; Processing feed speed 450～600mm/ minute; Described the 3rd the step in feed speed 10～20mm/ minute; The angle of awl cutter is 115～120 ° in described the 4th step, its effect is the wire casing that the top (with the intersection, outer) at wire casing can keep these parts, certain acute angle is arranged again simultaneously, because if use 160 ° of awl cuttves in these positions, angle too conference cuts away the wire casing of this part; Processing feed speed 450～600mm/ minute; Above-mentioned cutter hardness is Rockwell 80～90 degree, adds and cools off with cooling fluid man-hour, polishing of awl cutter and the each 0.2～0.3mm of feeding depth that cuts off.
The stainless iron of described employing or other spring steel sheet material, heat treatment reach about HRC 45-50 degree; The thickness of described metal caul is 0.3-5mm; Hardness is HRC20～45.The effect of metal caul is the protection magnetic chuck.
Raw material of the present invention need extraordinary thin plate springs steel of planarization or stainless iron, can be by magnetic attracting on processing platform.Because metal sheet surface fluting machining characteristics needs magnetic attracting, general anchor clamps can not satisfy the uniformity of groove depth, and anchor clamps can make processed area limited only simultaneously, increase the raw materials consumption waste.And general vacuum suction is because the horizontal cutting power of metal processing increases greatly and becomes infeasible.The present invention adopts magnetic absorption can satisfy processing request.
The hardness of material of the present invention is generally chosen the i.e. good material of the planarization after Overheating Treatment of raw material that has reached requirement hardness.Remake the then difficult technically realization of heat treatment after the processing, make the planarization variation because thin plate heat treatment tends to distortion.Hardness is chosen in HRC45-50.Be lower than Rockwell 45 degree and bend easily, can make the distortion of bed die wire casing place after repeatedly shovel descends at the wire casing place.Because the thickness of bottom land has only about 0.1-0.15mm, be higher than Rockwell 50 degree and make the processing difficulty that becomes make process time elongated, it is big that the cutter loss becomes, and cost obviously increases.
The present invention reduces client cost, and some oversupplied goods are only made disposable input, no longer needs to order more bed die, and spare part also reduces greatly.Install because bed die can shovel down repeatedly repeatedly, and bed die cell wall hardness height, not easy to wear, so bed die service life at least 5 more than 10,000,000 times, production cost reduces greatly.This technology reduces the operating time, boosts productivity, and does not reinstall or prints the situation of setting type again if die cutting plate takes place, and need not shovel down this bed die on the cross cutting backing plate, and direct upper plate cross cutting need not be installed bed die again during next time production.In addition, owing to there are not a large amount of disposable production waste products such as bed die bar, resin bed die sheet in the prior art,, improve environment so can reduce the production easily-consumed products.The present invention can replace imported material, makes the product production domesticization.Because the flatness of resin bed die material and thickness deviation require high, at present domestic still a large amount of import resin sheets.The present invention can replace with homemade metal material; The present invention simultaneously can not wait the life problems of other bed die goods that the quality of client's product is changed because of bed die sheet trough rim inner wall abrasion or bed die bottom land cracking, product impression seal consistently, steady quality.
