Description

A kind of sheet material cutting working method

Technical field the present invention relates to building, decoration, furniture, electric tool technical field, specifically, is a kind of building, decoration, the furniture method with the sheet linear cut.

Background technology is present; Whole nation building industry, decorate industry, furniture industry and there is shortcoming in the linear interpolation processing method of sheet material (alleged sheet material comprises flat-form material in the present specification; Also comprise semifinished material with all or part of plane; Like furniture table-board plate, door, architectural decoration door leaf, sash etc.); Particularly in the architectural decoration building site general a large amount of exist to length long, the horizontal sawing of rectangular slab wood plank very long, overlength has difficulties; At present, these industries have following method to the linear interpolation processing of above-mentioned material: a kind of is that desk-top carpenter's electric circular saw all has guide plate with desk-top carpenter's electric circular saw sawing wood plank; Bigger, long, the rectangle wood plank very long, overlength of ripping preferably; But the horizontal sawing of desk-top carpenter's electric circular saw (laterally the sawing phalanges saw plane of cutting is vertical with the long limit of rectangle wood plank) is bigger, long, rectangle wood plank very long, overlength difficulty, even very difficult, just almost can't the sawing of overlength; Because saw time bigger, center of gravity that is long, rectangle wood plank very long, overlength is far away from the saw blade plane, the effect of center of gravity power makes the carpenter be difficult to push this wood plank to saw blade reposefully.Second method is setting-out on sheet material, is attached to hand-held cutting machine planker lower plane to be cut above the sheet material, and along the line cutting processing, the shortcoming of this method is: the always good left and right sides of hand-held cutting machine is crooked; Cause the cut surface out-of-flatness, angle, scale error are big, and speed is slow; For example: carpenter's setting-out on wood plank earlier, cut along scroll saw with hand-held carpenter electric circular saw then, in the time of saw; The always good left and right sides of hand-held carpenter electric circular saw (carpenter claims Portable electric cicular saw) is crooked, and saw blade is always askew left a little while, and is askew to the right a little while; Cause the face out-of-flatness of sawing, size and angle take place than mistake, and the carpenter is in saw in addition; Because be afraid of askew more severe of saw blade, always dare not pick up speed, speed is slowed down.When bricklayer was pasted wall or subsides floor tile and subsides wall and pasted floor ceramic tile with hand-held cutting machine cutting marble, situation was identical with the situation of hand-held carpenter electric circular saw sawing wood plank with above-mentioned carpenter, and shortcoming is identical.The third method is that the carpenter leans on the limit of straight lath and by mobile above the wood plank of sawing, carries out sawing with hand-held carpenter electric circular saw planker sticking surface and planker lower plane, and the shortcoming of this method is: 1, fixedly the speed of straight board lath is slow; 2, size angle easy error; 3, the size angular error is big; Carpenter's situation of horizontal sawing wood plank in this way is: the carpenter will draw 2 road straight lines earlier, in order to the position of confirming that straight board lath is fixing on by the wood plank of sawing before sawing; One straight line is the position line that needs the face of sawing; The second road straight line is the fixing position line of straight board lath, and how many distances of this 2 diatom is, needs to measure and differentiate and confirm; 2 that will measure and remember hand-held carpenter electric circular saw planker sticking surface to saw blade rotation outline inner face and outside earlier apart from size; Hand-held carpenter electric circular saw is directly measured in measurement with chi the distance measurements of planker sticking surface to saw blade is inaccurate, use hand-held carpenter electric circular saw test saw plate, then by just energy is accurate on the plate of sawing; Confirming to differentiate 2 kinds of situation confirms: fallen on the wood plank not by sawing if straight board lath is fixed on preparation; The distance of this 2 road straight line equals the distance of hand-held carpenter electric circular saw planker sticking surface to saw blade rotation profile outside, if straight board lath is fixed on the wood plank that preparation wants, the distance of this 2 road straight line equals the distance (the rotation profile inner face is meant from the near saw blade rotation profile face of planker sticking surface) of hand-held carpenter electric circular saw planker sticking surface to saw blade rotation profile inner face; This measurement, resolution are confirmed and draw 2 road straight lines to waste time very much; And be easy to make mistakes and big error, after 2 road straight lines are finished, again straight board lath is fixed on by on the wood plank of sawing; Fixedly be to follow closely with nail; Have seldom the carpenter that counts with 2 compactors of prior art with straight board lath with compressed by wood plank 2 limits of sawing, occur size and angular error again easily in the time of fixing, and straight board lath is easy again and caused size and angular error by the wood plank generation phase shift of sawing sawing the time.The 4th kind of method is: with the hand-held cutter of prior art, the guide plate that comprises the cutting machine that trimmer, engraving machine (bakelite by name mills on the product description that has), hand-held carpenter electric circular saw, bricklayer that the carpenter uses are used leans on along the sheet edge that is cut processing and moves, and above-mentioned hand-held cutter planker lower plane is pasted along being cut to move above the sheet material carry out cut; The shortcoming of this method is: guide plate is very short; Long less than 20 centimetres, short has only 3 centimetres, and guide board structure is softer; During cutting; Cutter is swung easily, cause the cutting face not straight, and speed is slow.The 5th kind of method is: with plank, batten nail system (fixing) wooden guide groove and guide plate, nail is made (fixing) blend stop, guide groove and saw blade plane parallel to carpenter oneself on the guide plate on the wooden working plate of the easy desk-top electric circular saw of carpenter; Blend stop is vertical with the saw blade plane, and the carpenter will be pressed on the guide plate by the wood plank that sawing is processed with hand and be close to blend stop, the saw blade of pushing to rotate; The rectangle wood plank is carried out horizontal sawing, and this method shortcoming is following: 1, can't carry out horizontal sawing to rectangle wood plank very long, overlength, because the length and width of guide plate is limited; When decorateing; A lot of rectangle wood plank length is more than 1 meter more than 2 meters, and more than more than 1 meter, what have reaches more than 4 meters in most rectangle wood plank length on the construction site; So long sheet material, the carpenter can't be pressed in it on guide plate with hand.2, ripping and horizontal sawing can not be carried out simultaneously, because the necessary guide plate of ripping has blocked horizontal sawing by the path of the wood plank of sawing.3, block wood sawdust in the guide groove easily, stop that guide plate advances.4, volume is big, and carrying is difficult.The 6th kind of method is with the special-purpose iron and steel machine that has guide rail sheet material to be carried out portraitlandscape linear interpolation processing, and the shortcoming of this method is that these machine volumes are big, weight is big, price is high.

At present; Some carpenter have simple usefulness draw a picture 90 degree vertical lines the angle guiding ruler (carpenter who has be called big curved chi, greatly turn chi, turn chi); This angle guiding ruler structure is similar a bit with guiding ruler of the present invention; It is fixed by the lean on piece and the blade of cuboid, and the blade working edge that leans on piece sticking surface and planar shaped of its planar shaped becomes an angle of 90 degrees, leans on the piece sticking surface to lean against the edge of material during setting-out; Lean on suitable blade working edge to move the line vertical that to draw with pen with the material limit; This angle guiding ruler does not have guiding ruler blade elongated portion of the present invention, guiding ruler handle, visits line fetters, increases the frictional force device, and size is less, and to lean on piece all be solid wooden unit or metal derby with wooden blade or metal blade bonds and fix.
