Abstract
The invention relates to drawing and straightening equipment for belt and sectional materials, belonging to the field of metal finishing and manufacture. A drawing and straightening integrated machine is characterized in that a machine body is simultaneously provided with a drawing device and a straightening device, a feeding position of the machine body is provided with a drawing mold for assembly, a tail end of the machine body is provided with a drawing trolley, and a straightening chuck is arranged on a machine body between the drawing mold and the drawing trolley. In the invention, the drawing device and the straightening device are arranged on the same machine body, and the straightening chuck is a replaceable tooling straightening chuck and is applicable to production of products with various section shapes. Stretcher straightening is characterized in that pure drawing force is applied to a material to elongate the belt material to enable the belt material to undergo elastoplastic deformation, after stress is eliminated, an elastic level and a shrinking level are same or approximate so that the situation that the material becomes straight or curved is alleviated is achieved, and thus, the material is straightened to a certain extent.
Description
Technical field
The invention belongs to metal processing and manufacturing field, relate to the tension straingtening equipment of band and section bar.
Background technology
It is following several that existing band or section bar obtain technique:
At first by horizontal extruder heated bar is squeezed into band or the section bar of segmentation, then pickling, then drawing is proofreaied and correct shape and is obtained accurate sectional dimension, at last logical aligning and fixed length intercepting acquisition final products.
The metal casting of melting is caused band or the section bar of various cross sectional shapes by continuous casting equipment, these products are compared with horizontal type extruding technique and can be produced long length, pass through crimping machine harvest spool, then by the rolling-cogging of multi-pass, obtain final products by pickling, drawing, scale intercepting and aligning again.
Obtain any surface finish, the more accurate product of size uniform by continuous extruder, then product is directly obtained final products by drawing, scale intercepting, aligning by the spool of harvest.
Which kind of find by more various process routes: regardless of the band or the sectional material blank that obtain by mode, all need to obtain through drawing process the hardness of final accurate dimension, surface smoothness and customer requirement, then obtain the final products that the user needs by the scale intercepting.The deficiency of these techniques is that drawing and straightening process separately carry out, and increases processing step, and factory need to pay more manpowers and time cost, need the longer production time, producing can not serialization, the product length size is difficult to accurate assurance.For the aligning of section bar, existing straightening process all more complicated is time-consuming in addition.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of tension straingtening all-in-one is provided, simple in structure, integrate drawing and straightening process, to save man-hour and produce continuously, automaticity is high.
The technical scheme that the present invention adopts for achieving the above object is: the tension straingtening all-in-one, draw-off gear and straightener are installed on the body simultaneously, draw-off gear comprises drawing mould and draw trolley, draw trolley comprises the drawing chuck, straightener comprises aligning chuck and aligning oil cylinder, drawing mould is installed in body charging place, the body end is equipped with draw trolley, the aligning chuck is housed on the body between drawing mould and the draw trolley, be fixed on the drawing hydraulic oil cylinder driving draw trolley on the frame, dispose one group two aligning oil cylinders in drawing oil cylinder both sides, the drawing stroke is finished by the drawing oil cylinder, and the aligning stroke is finished by three common application of forces of oil cylinder.
On the body cutting device is housed also between described aligning chuck and the draw trolley, cutting device adopts servo electric saw or hydraulic shear.
Described body top discharge station place is equipped with delivery roller frame and product delivery roller.
Described aligning chuck adopts replaceable frock aligning chuck.
Described draw trolley is with self-locking mechanism, and self-locking mechanism is installed on the draw trolley backboard, and it is that locking cylinder drives the connection locking sliding block, and locking sliding block is connected with aligning oil cylinder head opening-closing locking.
Described dispose in drawing oil cylinder both sides one group two the aligning oil cylinders, the drawing stroke is finished by the drawing oil cylinder, the aligning stroke finished by three common application of forces of oil cylinder.
Described drawing oil cylinder is regulated different product and pulling capacity and the drawing speed of producing different operations by the hydraulic electric control servo-drive system.
Product cross section Character adjustment rotating speed and feed speed that described servo electric saw is inputted in man-machine interface according to the user.
Described drawing chuck adopts the drawing chuck of replaceable frock, to adapt to the product of various cross sectional shapes.
Described close drawing mould assembling exit position arranges the product length measurement mechanism, generally selects optical measuring device, if product length requires length accuracy less demanding, also can adopt encoder or at multiple spot travel switch is set.
Described body upper feeding station disposes pay-off.
Draw-off gear of the present invention and straightener are contained on the body, and the aligning chuck adopts replaceable frock aligning chuck, can adapt to the production of various cross sectional shapes.Stretcher leveling is by material being applied simple pulling force, makes the band elongation, and whole section upper stress meets or exceeds the yield limit σ of material
sAnd the extensibility of corresponding generation 1% ~ 3%, make it to produce elastic-plastic deformation, remove tension after, bullet contracting amount equates or approaches to equate, makes material become straight or curvature is reduced, thereby makes material obtain to a certain degree aligning.Because pulling capacity is generally less than σ
s/ 2, and straightening force need to approximate σ
s, unnecessary too huge in order to prevent oil cylinder in order to satisfy straightening force and to require, so designed aligning oil cylinder group.
Body upper feeding station of the present invention disposes pay-off, original station drawing straightening process of comparing, the waste of the chuck that can cut the waste.Discharging station place is equipped with delivery roller frame and product delivery roller, the discharging frame of product can be along the product up-and-down motion, the approach switch that moves back and forth by being installed on the alignment pay-off drives, when draw drum put down the position deviation production line center line of blank the time, product can be run into approach switch, approach switch will drive pay off rack and move reciprocatingly and regulate the position of pay off rack, so that put down blank just in time on the product center line, so that blank can not be subject to bending force.Present device can realize material loading, aligning, drawing, blanking whole-course automation, so that drawing and aligning once finish, and the production serialization, production efficiency is high, and production cost is low.
