Description
Technical field
The utility model relates to a kind of through the device in its stress distribution of saw blade body pressurized adjustment, belongs to the metalworking technology field.
Background technology
Metal circular saw is widely used in the various industries, is the common tool that is used for materials such as sawing stone material, steel, timber, aluminium.Because saw blade belongs to sheet type annulus product, poor rigidity, yielding in use, thereby its service life is shorter.
In order to increase the integral rigidity of saw blade; Prolong the service life of saw blade; Manufacturer generally can adopt modes such as hand bumping, cal rolling on the certain position of saw blade lamellar body, to carry out pressurized; The stress distribution of change or rerouting lamellar body itself makes it to possess rational stress distribution and rigidity situation.The handwork hammer striking is lower to the requirement of equipment, only needs platform, hand hammer to get final product, but workman's operative skill is had relatively high expectations, and is difficult for realizing big batch process, and the saw blade stress distribution after handling simultaneously is inhomogeneous.The cal rolling method is to utilize the same position of a pair of running roller in saw blade lamellar body two sides on the vertical or horizontal stress roller that lamellar body is applied certain pressure; And drive saw blade by the running roller of active rotation and rotate, extrude the some NOL rings concentric on the lamellar body surface with saw blade.Because the metal at NOL ring place is extruded distortion, thereby has adjusted the stress distribution of blade body, can make saw blade obtain satisfactory stress value through adjustment roll-in position.But owing between the NOL ring certain interval is arranged with one heart, actual stress is easy to generate STRESS VARIATION very inhomogeneous along distributing on the saw blade radial direction in saw blade weldering tooth, saw blade use, had a strong impact on the sawing effect and the service life of saw blade.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of saw blade radially to roll treating apparatus with the tangential combined stress, to improve the stress distribution of blade body, improves saw blade rigidity and service life.
The said problem of the utility model realizes with following technical scheme:
A kind of saw blade radially rolls treating apparatus with the tangential combined stress; Comprise frame and rack-mounted saw blade mount pad, last rolling wheel set, following rolling wheel set and rolling wheel set drive unit in the formation; Waiting to roll saw blade is installed on the saw blade mount pad through vertical rotating shaft level; Last rolling wheel set and the symmetrical roof pressure of following rolling wheel set roll on two sides of saw blade waiting, their rolling direction is the tangential direction of saw blade, after the improvement; Between saw blade mount pad and frame, also be provided with horizontal slide rail, said horizontal slide rail and last rolling wheel set are positioned at same perpendicular with following rolling wheel set.
Above-mentioned saw blade radially rolls treating apparatus with the tangential combined stress, and saw blade mount pad drive unit also is installed on the said frame.
Above-mentioned saw blade radially rolls treating apparatus with the tangential combined stress, and the said rolling wheel set that goes up is connected with frame through the vertical hydraulic cylinder.
The utility model has been set up saw blade and has been moved radially system on the basis of original saw blade rolling device, make the roll extrusion ring when roll the saw blade tangential, also does radial motion with respect to saw blade.This device can extrude netted stress impression in the saw blade surface roll, has not only improved the rigid nature of saw blade, and the saw blade surface stress is evenly distributed, and has prolonged the service life of saw blade.

The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model has increased horizontal slide rail 11 and saw blade mount pad drive unit 6 on the basis of conventional blade stress roll squeezer, and this device adopts footpath, tangential composite roll compression treatment process, and its procedure of processing is following:
1. be ready to cross the saw blade of flatness through alignment, its flatness index will reach below 0.2 millimeter, for the saw blade of diameter more than 2000 millimeters is the highest can not be above 0.3 millimeter;
2. place the position away from rolling wheel set to saw blade rotating shaft 10, its distance should be put in saw blade 5 endoporus on the rotating shaft 10 greater than the radius of saw blade 5;
3. move saw blade 5, and it is placed between two rolling wheel set, make two rolling wheel set to saw blade 5 motions, the contact back applies 1 to 8 ton pressure through hydraulic cylinder 4, makes rolling wheel set be pressed into the degree of depth of 0.02 to 0.15 millimeter of sheet surface;
4. start rolling wheel set drive unit 2; Make the rolling wheel set rotation, drive the saw blade lamellar body and rotate synchronously, meanwhile horizontal slide rail 11 radially moves saw blade mount pad 7 in the driving lower edge of saw blade mount pad drive unit 6; Rolling wheel set forms footpath, the compound roll-in ring track in tangential in the sheet surface; Every track is arc shape, adjustment rolling wheel set rotating speed, and saw blade mount pad 7 can obtain many roll-in vestiges through 5 to 20 reciprocating motions;
5. in order to extrude netted impression in the saw blade surface roll; After the roll-in of accomplishing single arcuation pressure ring, the adjustment direction of rotation is carried out reciprocal compound roll-in again; Just can obtain another group arc impression opposite with original impression bending direction; And corresponding one by one with it netted roll-in vestige, the homogenising of realization saw blade surface stress, raising saw blade rigidity and the serviceability of forming.
