Abstract
The utility model is configurated with a numerical control table on the opposite face of a common circle cutting shear with an improved design for holding and moving work pieces. The mutual position between a blank and a double-disc shear can be automatically changed according to a program for realizing the non circular curve cutting and tangential rectilinear cutting thereof. The machine removes the existing method that line needs to draw on a plate in advance; a hand holding plate needs to shear along line. The utility model has the advantages of high precision and high efficient, avoids dangerous operation environment, and is suitable to shear three outer circular arc curves on one end plate of a scroll of an axial-flow fan, archimedes spiral logarithmic spiral lines, etc.
Description
This machine is used for the roller shear blanking of steel plate (or other can use the sheet material of double plate scissor cut) non-round gabarit (or interior exterior feature).Non-round gabarit (or interior exterior feature) can be joined by several sections circular arcs and be constituted, and also can be spiral of Archimedes, equiangular spiral etc.These gabarits (or interior exterior feature) can have one section straight line tangent with it.
The shearing blanking of the non-round gabarit of this class (or interior exterior feature), at present, many employings setting-out on sheet material earlier, then, on common rotary shears, the manually-operated way of shearing along the line is finished.Its shear precision is low, operating rate slow, influenced by human factor, the quality instability.
The purpose of this utility model is to improve common rotary shears, makes it can shear the non-circular curve profile automatically, and profile can be set with numerical control program.
On common rotary shears, in shear history, the pivot and the distance between the scissors of workpiece are changeless, thereby, can only shear circular contour.The technical solution of the utility model is: in the shear history of workpiece, along with the rotation of workpiece, the distance between its pivot and the scissors is ceaselessly changed by the numerical control transmission mechanism, thereby shears out the profile of non-circular curve.
The utility model has kept fuselage, scissors and the scissors driving section of common rotary shears, shown in Fig. 1 left side.The right-hand part of Fig. 1 is that workbench is sent in realization numerical control of the present utility model to.Among the figure, following planker (11) is driven by leading screw (6), moves as left and right directions on support.Cylinder (9) is housed on the last plane of following planker (11), and planker (10) is being done moving of fore-and-aft direction on the planker (11) down in cylinder (9) driving.On last planker (10), the pallet (3) and the fixing clamp (5) that can rotate flexibly are housed.Clamp is by pneumatic opening and closing.
The course of work: the blank (4) of having gone out the centering circular hole is contained on the pallet (3), and chucking.Pallet (3) can freely rotate, and can drive the photoelectric encoder rotation coaxial with it.Blank (4) around the rotation of the center of pallet (3), simultaneously, drives the photoelectric encoder rotation under the shearing force effect of double plate scissors (1,2).The angular displacement signal input twin shaft digital control system that photoelectric encoder sends, this system is according to the functional relation of enrolling in the program, and control servomotor (7) drives leading screw (6) rotation.And then planker (11) is moved to double plate scissors (1,2) direction, so on blank, shear out the non-circular curve that the vector radius reduces gradually.
The profile of workpiece also has straightway, and when shearing straightway, claw (5) blocks a jiao of firm workpiece, and workpiece can not rotate in shear history, thereby shears out straight line.When shearing straight line, it is mobile that cylinder (9) promotes to be equipped with the last planker (10) of pallet (3), bump against buting iron (8) and on travel switch the time, clamp (5) unclamps, workpiece just can rotate, this has just finished connecting of straight line and extra curvature profile.
1., the productivity ratio height the utility model when gabarit that is used for axial flow blower spiral case end plate is sheared, has demonstrated following useful effect:: raise labour productivity more than 5 times than aforesaid existing method; 2., precision height: shear scale error and be reduced to 0.5mm by 1～2mm; 3., can shear complex curve:, replaced easy three-arc curve, thereby fan performance is improved owing to can shear out equiangular spiral.
Claims (2)
1. on common rotary shears, numerical control is set sends workbench to, realize the numerical control rotary shears that the distance between workpiece pivot and scissors changes by setting rule, it still utilizes the fuselage of common rotary shears, the scissors of scissors running part and former state, still by double plate scissors (1, tangential force when 2) shearing workpiece blank drives blank (4) rotation, different is on common rotary shears, the workpiece blank pivot maintains static, and the utility model has been realized the numerical control of workpiece blank pivot and has been moved, it is characterized in that: the pivot of blank---pallet (3), being contained in numerical control sends on the following planker (11) of workbench, when blank (4) rotates, blank (4) chucking pallet (3) thereon, drive the photoelectric encoder coaxial and send angular displacement signal with it, this signal input twin shaft digital control system, the latter is by predefined numerical control program, control servomotor (7) drives leading screw (6) rotation, and then make down planker (11) to double plate scissors (1,2) direction moves, this just makes the blank pivot---and pallet (3) is to double plate scissors (1,2) direction moves, thereby cause that blank pivot to the distance of scissors constantly dwindling, so, on blank, shear out the non-circular curve that the vector radius reduces gradually.
2. at the numerical control rotary shears of claim 1, shear the method that straightway is connected with the shearing curve section, when it is characterized in that shearing straightway, blank (4) is by air-actuated jaw (5) card jail, blank can not rotate, and planker (10) is when advancing in cylinder (9) driving, and what shear out is straight line; Last planker (10) move to run into spacing buting iron (8) and on travel switch the time, air-actuated jaw (5) unclamps blank (4) automatically, blank (4) is driven around the center of pallet (3) by double plate scissors (1,2) and rotates, promptly begin shearing curve, realized connecting of straightway and curved section, buting iron (8) is the stay bolt that can regulate and lock, regulates the length that buting iron (8) can change straightway.
