Due to the adoption of a harmonic speed reducing device, a spiral gap eliminating mechanism and the turnover transmission locking mechanism, the utility model has the advantages of high transmission efficiency, high precision, low energy consumption, low cost, high automatization degree, the capability adapting the shaping of plates with different bending and rolling diameters, small remained straight sides of the rolled steel plates, novel appearance, etc.
Description
The utility model is a kind of be used under cold state sheet metal the being processed into cylinder of various different sizes, adjustable three rolls plate bending machine of lower roll level of conic tube.The harmonic wave speed reducing machine transmission is adopted in main transmission.
The pattern of veneer reeling machine commonly used has symmetrical expression, asymmetric, down-regulation type and four-roller type veneer reeling machine both at home and abroad at present.The symmetrical expression veneer reeling machine needs auxiliary equipment to carry out pre-bending because of its remained straight edge is bigger, and twist technology trouble of asymmetric veneer reeling machine needs the tune elbow, and top roll and limit roller can not add carrying roller, thereby can not develop big specification for adjusting roller; The four-roll plate bending machine complex structure, weight is big, the cost height.
The purpose of this utility model is to provide a kind of compact conformation simple, can symmetry twist, again can asymmetric elbow, have the favorable manufacturability energy, it is little to add the man-hour remained straight edge, does not need to reverse end for end elbow, easy and simple to handle, the harmonic reduction lower roll horizontal adjusting formula three rolls plate bending machine of less energy consumption.
Technical characterictic of the present utility model is: this machine is made of top roll transmission device, top roll lowering or hoisting gear, following roller arrangement, overturning transmission retaining mechanism, top roll stand apparatus, case, base, the assembling of balancing pull rod parts.The top roll transmission device is constituted by motor, harmonic speed reducer, gear coupling, support, snap ring, top roll, bearing body, axle sleeve, plate washer, live bearing.The rapid circular movement of motor is converted into low-speed rotation.In the top roll transmission device, the power shaft of harmonic wave speed reducing machine connects with motor, and output shaft connects with top roll by gear coupling, has replaced original involute gear reducing gear, drives the outmoded structure that lower roll rotates.Harmonic speed reducer is by rigid gear, flexible gear, and wave producer, flexible bearing assembling with major and minor axis constitute.After wave producer and flexible bearing were packed flexbile gear into, flexbile gear became ellipse, and the flexbile gear external tooth is meshed with just taking turns internal tooth, formed two region of engagements, and the minor axis two ends are in full disengaged condition.When wave producer rotated, flexbile gear was at the crest place of two deformation wave, and the local region of engagement that forms with firm wheel constantly changes the position of engagement.Because flexbile gear exists the number of teeth poor with firm wheel, make flexbile gear and side set motion has clocklike just taken place between the wheel, the result that side set moves just gives driven shaft with the motion and the transmission of power of driving shaft.On the slide of following roller arrangement, also be provided with the screw thread that can adjust thread pitch to pay, screw thread is paid by screw rod, packing ring, adjustment pad, adjusts nut, bolt, slide, round nut, nut, guide rail formation.A nut is packed on the slide, the rotatable adjusting of another nut; By suitable angle adjustment, can obtain best drive gap.
The top roll lowering or hoisting gear by motor, yielding coupling, decelerator, clamping coupling, connect axle, clutch, worm reducer, screw rod, pin are connected with bearing block with the overturning frame, change rotatablely moving of motor the vertical displacement movement of top roll into, provide pre-bending and the pressure that twists and guarantee the position that overturning is freely thrown off.Overturning transmission retaining mechanism is housed on base, in its mechanism, bearing block is housed, the conical gear case is housed on bearing block, connecting rod is housed on the output screw top of conical gear case, lower end and worm gear reducer at connecting rod are hinged, and the upper end and the guide rod of connecting rod are slidingly connected.Guide rod is fixed on the overturning frame.Rotatablely moving of motor changed the rectilinear motion of screw rod into through bevel gear reducer, drivening rod rotates, and rotatablely moving of connecting rod forces the overturning frame to rotate, and bearing pin moves in the chute of overturning frame simultaneously.By two mechanisms rotatablely moving of motor is converted into rotatablely moving of overturning frame.The overturning frame is thrown off from roller, take out workpiece smoothly.Following roller arrangement motor by clamping coupling, connect axle, clutch, worm reducer, screw rod and be connected with bottom roll bearing block, two lower rolls are fixed on the bearing block by axle sleeve, interaction by said mechanism, change rotatablely moving of motor into lower roll move horizontally, to realize the variation of three roller relative positions, to finish respectively twist straight flange and the symmetrical action that twists.
The utility model has the advantages that: owing to be provided with harmonic speed reducer, harmonic gear can be realized very big gearratio in complete machine, and harmonic speed reducer reduces 20%～50% than cylinder gear speed reducer volume, and number of spare parts reduces half.The face contact is touched more than toe joint between the flexbile gear of harmonic speed reducer and the firm wheel, and sliding speed is little, and wearing and tearing are even, the bearing capacity height, and stable drive, nothing is impacted and noise; Adopt the two-way screw thread of adjusting thread pitch to pay in the transmission owing to moving horizontally, can realize not having the sideshake high-precision engaging, improved lower roll running fix and lower roll portable terminal positioning accuracy at lower roll.Owing to be provided with overturning frame plane contact mechanism, replaced the retaining mechanism of having strong market potential of veneer reeling machine of the same type, improved automaticity, installation and maintenance are convenient.The complete machine structure novelty, good looking appearance, compactness, function are many, power consumption reduces to 40% than similar veneer reeling machine, the also corresponding reduction of production cost, remarkable in economical benefits.
