Abstract
The present invention is an improvement of application No.96109044.8 and is mainly used to extrude precise aluminium shape product.The extruder has one counter, one interpreter at the position parallel to moving cross wall to sense the length of aluminium ingot, one interpreter at one end of dragger to sense the length of the product.When the dragger interpreter senses the set length, the dragger stops and the extruder stops extrusion; and when the counter counts the set number, the length of residue ingot is judged. The present invention has short job period, less residue ingot and waste and high precise extrusion efficiency.
Description
The present invention relates to a kind of processing method and device of aluminium section bar
The hot extrude aluminium section bar is widely used in building, automobile, aerospace industry in modern society ... in modern product, yet under the ever-increasing situation of aluminium alloy range of application, be applied to making more accurate, exquisite product more widely, and because of it uses the moulding nib less, the volume of each finished product is few far beyond common architectural shape.
As shown in Figure 6, be prior art extruder structure configuration schematic diagram.Wherein extruder 1 ' crosstie wall 11 ' front end be provided with depression bar 13 ', cake of press 14 ', be marked with B person among this figure for squeezing the stub ingot that type ends, to avoid if reluctantly aluminium ingot is all extruded, then cake of press 14 ' certainly will smash mould 15 '.Again crosstie wall 11 ' above be provided with the limit switch 12 of manual adjustment position ', when 12 ' time of crosstie wall 11 ' contact limit switch, crosstie wall 11 ' stop, meaning be depression bar 13 ', cake of press 14 ' stop, and output control hauling machine 3 ' stop action.
When being used to implement the accurate material extruding of moulding in the general section bar mode of extruding commonly used, because the volume of accurate extrudate finished product is much smaller than the volume of general extrudate, (at present general extrudate volume greater than the about 2-10 of accurate extrudate doubly), as make be written into ingot-containing tube 15 ' aluminium ingot when only precision of moulding is squeezed the type finished product, must be written into the stub ingot B that still needs residual vast scale after very short aluminium ingot raw material and the each moulding, the waste ratio of stub ingot B is high temporarily.
Again because ingot-containing tube 15 ' volume all can place the short ingot of the some accurate extrudate finished products of moulding, and if ingot-containing tube 15 during each extruding ' interiorly only be written into a short ingot extrusion modling, promptly cause ingot-containing tube 15 ' can't give full play to its benefit, and must make ingot-containing tube 15 ' mobile opening constantly again after forming each extruding, be written into another short ingot again, make the backlash of this extruder increase and reduce it and push efficient.
As shown in Figure 7, for reducing the stub ingot loss and increasing extruding efficient, at present preferable mode be when the accurate section bar of extruding must through artificial primary Calculation (calculate ingot-containing tube 15 ' the plastic some precisions of volume squeeze type finished product 17 '), again ingot-containing tube 15 ' in be written into the aluminium ingot of corresponding primary Calculation suitable length, but this aluminium ingot when cutting, set its length one-shot forming set accurate squeeze a type finished product 17 ', be provided with some adjustable again near switch 18 ' and 19 ' [be provided with two among the figure near switch in crosstie wall 11 ' shift position, should near switch 18 ' and 19 ' with extruder 1 ' shutdown switch be connected], nationality is artificial before the moulding adjusts near switch 18 ' and 19 ' position, when extrusion modling makes the depression bar 13 ' extruding of advancing, crosstie wall 11 ' contact first near 18 ' time of switch, can make extruder 1 ' stop, again order skid off buck on the platform cut off the finished product 17 extruded for the first time ', the platform that skids off by hauling machine 3 ' connection pulls it again.
Restart extruder 1 ' action, make that depression bar 13 ' extruding moves on, when second of crosstie wall 11 ' touch near 19 ' time of switch, can make extruder 1 ' stop, push for the second time finished product 17 ' pull out by skidding off platform again, restart extruder 1 ' action depression bar 13 ' advance extruding and crosstie wall 11 ' contact limit switch 12 ' time extruder 1 ' stop, and pull out the 3rd push finished product 17 '.The cake of press 14 of depression bar 13 ' front end ' and mould 16 ' leave stub ingot B, the mold damage 16 to prevent cake of press 14 ' directly impact '.
Above-mentioned fashion of extrusion can make the some extruding finished products 17 of aluminium ingot moulding in regular turn that once are written into ' and only residual stub ingot B, can significantly reduce the waste of stub ingot B, and minimizing (per three moulding strokes of backlash during because of extruding, reduce the secondary backlash time, that is reduce the generation of two sections stub ingots), this just can increase substantially extruding efficient.But also there is following shortcoming in this fashion of extrusion when actual job:
Because accurate extruding finished product 17 ' the volume exquisiteness, its volume is much smaller than the volume that is written into aluminium ingot, making a bit of aluminium ingot of extruding is plastic considerable extruding finished product.
If the platform length that skids off of hauling machine 3 ' be connected with is 20000MM, when finished product length is made as 1500MM, skid off platform and can hold 12 sections extruding finished products at every turn, its total finished product length is 18000MM, and the sawdust that at every turn cuts loss is 5MM, and then 12 sections sawdust are 60MM, thereby desirable extruding finished product 17 ' length should be 18060MM, and allowable error is 200MM during present actual operations for forming, thus extruding finished product 17 ' length should be 18060MM-18260MM.
When establish aluminium ingot with the extruding finished product 17 ' length ratio be 1: 100, can make when then aluminium ingot length is for 180.6MM the extruding finished product 17 ' length be 18060MM, when operating personnel adjust before extrusion modling when making extruding finished product 17 ' length be 18300MM near switch, also must adjust again near switch and make extruding finished product 17 ' length shorten 40MM at least and reach in the allowed band of 18260MM.
Thereby must adjust 0.4MM again near switch at least, " length is in the allowable error scope just to make crowded type finished product 17.
Yet since near switch be arranged on extruder 1 ' on a kind of mechanical type slide and adjust switch, so real difficult small distance of accurately adjusting to 0.4MM of manual operation, in fact will move slightly near switch, the distance that moves near switch is caused greater than 0.4MM adjust back extruding finished product 17 ' error in length bigger.
So adjusting at present near switch is to cause accurate main difficult point of squeezing the type operation.When adjustment makes crowded type finished product 17 ' length slightly exceed the allowable error scope near switch, for avoiding adjusting the increase that may cause error near switch again, generally promptly no longer adjust, just the slightly long extruding finished product 17 of extrusion modling ' after cut again and exceed part, thereby cause the increase of waste material.
Embodiment shown in Figure 7 is when adjusting first near 18 ' time of switch, and second near switch 19 ' also must correspondingly adjust, and this just more increases the degree of difficulty of adjusting, and makes to adjust operation and expend many operations for forming man-hour, thereby has reduced extruding efficient significantly.
2. the difficulty of accurately adjusting, make its extruding finished product 17 after the extrusion modling ' length FE be slightly larger than preseting length FD, make after the moulding DE section to be cut and to cause waste.
3. import ingot-containing tube 15 ' aluminium ingot length by artificial calculating, the oversize loss of stub ingot B takes place in regular meeting.
The objective of the invention is to the Programmable Logic Controller (PLC) that extruder is provided with counter or has tally function, also available have a line number function conventional arrangement, limit switch and hauling machine position at extruder are provided with the linear position decipherer respectively, counter is set and meter is recorded the radical that an aluminium ingot is extruded finished product, every extruding once be automatic pause cut and derive continue automatically after time of finished product extruding until counter reach stop squeezing after setting number and judge stub ingot length again feedback signal adjust aluminium ingot hot shears length, to reduce the defective material of aluminium ingot and finished product most effectively.
