The constant velocity mating gears drive two parallel round screw die shafts to make uniform motion in negative directions through a coupler. The two round screw die shafts are respectively sheathed with an eccentric sleeve, a pair of mating gears is fixed on the eccentric sleeve, and the round screw dies are arranged on the round screw die shafts. The utility model has the advantages of convenient exchange and assembly of the round screw dies, reasonable distribution of the force which the round screw dies bear, easy guarantee of the requirement of the concentricity of the center of the round screw dies of each pair of round screw dies, etc.
Description
The utility model relates to machine for shrinking, especially cantilever pipe contracting machine.
Machine for shrinking is the special machine bed of industrial electric apparatus and household electrical appliance electrothermal tube undergauge.Several problems below existing machine for shrinking exists: 1. all each to the roller speed unanimity, thereby make the linear velocity of axial elongation after the electrothermal tube compression and running roller inconsistent, cause roll to electrothermal tube at each to involving mutually between the running roller, both influence crudy, increased the waste of the power of motor and the energy again.2. running roller is to be contained in the middle of the two stands, is unfavorable for assembling and changes running roller.3. two running roller centre-to-centre spacing adjustment are to realize by moving of upper roll wheel, make every pair of running roller center decentraction like this, thereby influence the linearity of workpiece.
The utility model purpose just provides a kind of linear velocity of every pair of running roller and elongation after the workpiece compression of making and is complementary, and is convenient to assembling and changes running roller, and regulate running roller centre-to-centre spacing, helps improving the cantilever pipe contracting machine of workpiece crudy.
Cantilever pipe contracting machine is made of lathe bed, motor, reduction box, roller bracket, running roller etc.Be provided with a pair of reduction gearing, Worm screw and worm-gear drive and a pair of constant speed meshing gear in the reduction box, reduction box links to each other with roller bracket by shaft coupling.Be provided with the rolling axle of pair of parallel in the roller bracket, be with eccentric bushing on the rolling axle respectively, eccentric bushing cylindrical and endoporus have off-centre, and the eccentric direction of two eccentric bushings is opposite during assembling.The outside of two eccentric bushings is with pair of engaged gears respectively, and gear is fixed on the eccentric bushing.When an eccentric bushing turns an angle, another eccentric bushing is the same angle of opposite spin also, two running roller centre-to-centre spacing have been regulated at this point, make the centre-height of two pairs of running rollers remain unanimity, the end of rolling axle outside roller bracket links to each other with shaft coupling, the other end is suspended at outside the support, assembling running roller on it.
Cantilever pipe contracting machine of the present utility model has been compared following advantage with existing machine for shrinking:
1. owing to adopt the Worm screw and worm-gear drive replacement many to gear, not only simplify structure, reduced manufacturing cost, and the number of teeth of utilizing the interior reduction gearing of reduction box to pay increases and decreases and make running roller reach different rotating speeds, so substantially, satisfied the needs of workpiece, reduced back force of sliding friction greatly running roller to every pair of running roller linear velocity.Facts have proved that the lathe of same size energy-conservationly reaches 36.3%.
2. owing to close each linear velocity that distributed mutually, make the stressed distribution of running roller more reasonable, thereby more help improving the crudy of workpiece running roller.
3. because running roller is a cantilevered, therefore saved the time of assembling and replacing running roller.
4. because of the difference of workpiece material, its compression ratio is also inequality, and the centre-to-centre spacing that all needs to regulate running roller because of the wearing and tearing of running roller groove, owing to adopt the eccentric bushing adjustment structure to replace original bolt and nut to pay adjustment structure, therefore be easy to guarantee each roll centres degree requirement, thereby improved the linearity quality of workpiece running roller.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model kinematic scheme;
Fig. 3 is the utility model roller shelf structure schematic diagram.
Cantilever pipe contracting machine is made of lathe bed 8, motor 5, reduction box 6, roller bracket 2, running roller 1 etc.Be provided with a pair of reduction gearing that is meshed 9,10 and Worm screw and worm-gear drive 7 and a pair of constant speed meshing gear 4,5 in the reduction box 6, gear 10 links to each other with Worm screw and worm-gear drive 7 by axle 14, and Worm screw and worm-gear drive 7 links to each other with gear 4a by spools 15.Reduction box 6 links to each other with roller bracket 2 by shaft coupling 3.Be provided with rolling axle 11a, the 11b of pair of parallel in the roller bracket 2, be with eccentric bushing 12a on the rolling axle 11a, be with eccentric bushing 12b on the rolling axle 11b, the cylindrical of eccentric bushing 12a, 12b and endoporus all have 0.5 millimeter off-centre, and the eccentric direction of two eccentric bushings is opposite during assembling.The outside of eccentric bushing 12a is with gear 13a, and gear 13a is screwed on eccentric bushing 12a, and the outside of eccentric bushing 12b is with gear 13b, and gear 13b is screwed on eccentric bushing 12b, and gear 13a, 13b are a pair of gear that is meshed.When an eccentric bushing turned an angle, another eccentric bushing is the same angle of opposite spin also, had so just guaranteed the centre-to-centre spacing unanimity of two running rollers.Rolling axle 11a, the 11b end outside roller bracket 2 links to each other with shaft coupling 3a, 3b, and the other end is suspended at outside the roller bracket 2, assembles running roller 1a, 1b on it respectively, and workpiece is undergauge under the pressure rolling of two running roller 1a, 1b.
The workpiece principle of cantilever pipe contracting machine: motor 5 driven gears 9,10, slow down through gear 9,10, drive Worm screw and worm-gear drive 7 motions by axle 14, Worm screw and worm-gear drive 7 is by axle 15 driven gear 4a, and the gear 4b that is meshed with gear 4a rotates thereupon.Through the transmission of shaft coupling 3a, 3b, rolling axle 11a, 11b move in the other direction.Because gear 4a, 4b are the constant speed meshing gear, therefore, running roller 1a, the 1b on rolling axle 11a, the 11b also does movement at the uniform velocity in the other direction.
Only need utilize reduction gearing 9,10 numbers of teeth increase and decrease in the reduction box 6 in the running roller roll system, just can make every pair of running roller reach different rotating speeds, satisfy the needs of workpiece every pair of running roller linear velocity.
