Abstract
The invention discloses a supporting device for a lower roll of a four-roll plate coiling machine, which comprises a lower roll, wherein both sides of the lower roll are respectively provided with a lower roll seat, double rows of aligning roller bearings, a supporting seat, a piston rod, an oil cylinder and a rack of the plate coiling machine from top to bottom; and the lower roll seats are arranged at the left end and the right end of the lower roll, the double rows of aligning roller bearings are arranged inside the lower roll seat and are also installed on a left shaft neck and a right shaft neck of the lower roll, the lower roll seat and the supporting seat are connected in a matching way by a circular arc face which contacts with the lower roll seat and the supporting seat, the lower end of the supporting seat is connected with the piston rod by a pin shaft, a piston of the piston rod is sealed in the oil cylinder, and the bottom of the oil cylinder is connected and fixed with the rack of the plate coiling machine. The supporting device for the lower roll of the four-roll plate coiling machine has the advantage that the problems that a lower roll device of a traditional four-roll plate coiling machine has small bearing capacity and low transmission efficiency, the stressed deformation of a lower roll is large, the transmission efficiency is lower and the lower roll can not be inclined can be solved.
Description
Technical field
The invention belongs to veneer reeling machine manufacturing technology field, be specifically related to a kind of roller bearing under the four-roll plate bending machine that lower roll can tilt that makes.
Background technology
The following roller bearing of four veneer reeling machines of the prior art mainly contains two kinds: a kind of each row bearing, bottom roll bearing block, bearing gland and bottom roll bearing block slide plate that is installed in the lower roll two ends by lower roll, respectively formed; Another kind of sliding bearing by lower roll, lower roll two ends, with the blade fin of supporting base, bottom roll bearing block and the supporting base of the bottom roll bearing block of automatic setting circle cambered surface, supporting lower roller base, connect the connecting pin composition of lower roller base and supporting base.
The lower roll of four-roll plate bending machine is in Installation and Debugging or use; Need lower roll and top roll not parallel; Promptly descend roller arrangement to have tiltable function, but first kind following roller arrangement is arranged bearing because of only install one at the lower roll two ends, bearing capacity is little; Respectively a bit being combined into about the stressed supporting-point of lower roll is 2 points, and the amount of deflection that the lower roll stress deformation produces is bigger; And second kind of following roller arrangement adopts sliding bearing, and friction torque is big, and it is big to consume effective power clearly, inefficiency.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, provide a kind of and can make roller bearing under the four-roll plate bending machine that lower roll tilts.
Technical scheme: the following roller bearing of a kind of four-roll plate bending machine of the present invention, comprise lower roll, said lower roll both sides are respectively equipped with lower roller base, double self-aligning roller bearing, supporting base, piston rod, oil cylinder and veneer reeling machine frame from top to bottom; Said lower roller base is located at the lower roll right ends; Said double self-aligning roller bearing is located at lower roller base inside and is installed on the axle journal of the lower roll left and right sides; Said lower roller base and arc surface adaptive be connected of supporting base through both contacts; Said supporting base lower end is connected with piston rod through bearing pin, and the piston seal of said piston rod is in oil cylinder, and said oil cylinder bottom is connected fixing with the veneer reeling machine frame.
As optimization, also be provided with bearing gland on the said lower roller base, also be provided with the oil sealing baffle plate on the said bearing gland.
As optimization, also be fixedly connected with the axle head baffle plate on the axle journal of the said lower roll left and right sides.
As optimization, said bearing pin end is provided with the bearing pin baffle plate in said lower roll inboard.
As optimization, said oil cylinder Shanghai is provided with oil cylinder cover, is provided with the guiding gland above the said oil cylinder cover.
Beneficial effect: of the present invention being a little can solve the problem that the roller arrangement bearing capacity is little, transmission efficiency is low, the lower roll stress deformation big, transmission efficiency is lower, lower roll cannot tilt under the existing four-roll plate bending machine.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing example the present invention is described further:
Shown in accompanying drawing, a kind of following roller bearing of four-roll plate bending machine comprises lower roll 1; Lower roll 1 both sides are equipped with lower roller base 4; Double self-aligning roller bearing 6 is installed in the lower roller base 4, and axle head baffle plate 5 is fixed on lower roll 1 left and right sides axle journal, and oil sealing baffle plate 2 usefulness bolts are connected on the bearing gland 3; Bearing gland 3 usefulness bolts are connected lower roller base 4 inboards, and double self-aligning roller bearing 6 is connected with lower roll 1 left and right sides axle journal; Lower roller base 4 bottoms and supporting base 7 are for arc surface is connected, and supporting base 7 is connected through bearing pin 8 with piston rod 10, and bearing pin baffle plate 9 is fixed by bolts on the supporting base 7; Restriction bearing pin 9 stressed plaies; Lower roller base 4 moves up and down in veneer reeling machine frame 14 guide rails with supporting base 7, and guiding gland 11 usefulness bolts are installed on the oil cylinder cover 12, and piston rod 10 passes guiding gland 11, oil cylinder cover 12; Oil cylinder 13 tops are connected with oil cylinder cover 12 usefulness bolts, and oil cylinder 13 bottoms are connected with veneer reeling machine frame 14 usefulness bolts.
The present invention has following advantage:
Lower roll left and right sides axle journal is installed double self-aligning roller bearing respectively; About the stressed supporting-point of lower roll respectively be at 2 and be combined into 4 points; The supporting constraint that the double self-aligning roller bearing in the stressed back of lower roll is produced is a fixed constraint; Stressed lower roll distortion amount of deflection reduces than original structure, and the more original single bearing load of double self-aligning roller bearing increases with double, and lower roll uses the operating efficiency of the more former sliding bearing of double self-aligning roller bearing to improve.
The oil sealing baffle plate is with on the bolt bearing gland, and the oil sealing baffle plate is pushed down the J-shaped oil sealing, and the J-shaped oil sealing had both sealed the lubricating oil of double self-aligning roller bearing, plays dustproof effect again; Lower roller base and supporting base mating surface are arc surface, allow lower roll to install, and allow lower roll volume awl tube to tilt automatic capturing leveling in the time of making lower roll roll steel plate; Supporting base is connected with bearing pin with piston rod and locatees, and the bearing pin baffle plate is equipped with screw in the bearing pin end, and the bearing pin baffle plate after fixing prevents the stressed play of bearing pin, connects like this to make installation and maintenance convenient.
The guiding gland is connected on the oil cylinder cover with bolt; Oil cylinder cover and oil cylinder connect as one with bolt, are connected with bolt with the veneer reeling machine frame in described oil cylinder bottom and fix, and make described supporting base, bearing pin, piston rod, guiding gland, oil cylinder cover, oil cylinder and frame horizontal direction location; And supporting base, bearing pin, piston rod only can move up and down; Simple in structure like this, make the lower roll tiltable, lower roll can be synchronous.
