Abstract
The invention provides a four-roller plate rolling machine. The four-roller plate rolling machine comprises an overturning device, a short rack device, an upper roller device, two side roller devices, a lower roller device, a high rack device, a balance device, a hydraulic transmission device, a hydraulic system and a base. The upper roller device comprises a support, a fixing base, an upper roller, a taper sleeve, a bearing block and a coupler, wherein the upper roller is fixed between the support and the fixing base, the taper sleeve is connected to the end of the upper roller, and the bearing block is connected to the middle portion of the upper roller. The upper roller device further comprises a pull rod connected with the fixing base, and a worm and gear speed reducer connected with the pull rod, and the taper sleeve is fixed to the support. The four-roller plate rolling machine has the following technical effects that the work roller load is balanced, and the plate rolling efficiency is high.
Description
Technical field
The present invention relates to a kind of four-roll plate bending machine, belong to technical field of mechanical equipment。
Background technology
Veneer reeling machine (RollingMachine) is the moulding lathe that sheet material carries out continuity point bending, has the function of the difformity sheet material such as the O type that rolls, U-shaped, multistage R。
Veneer reeling machine is divided into three rollers and four rollers by the quantity of working roll。It is little that four-roll plate bending machine is easy to end pre-bending, remained straight edge。The operation principle of four-roll plate bending machine is top roll is main transmission, motor via reducer provide moment of torsion for it。Middle lower roll, front offset roll and rear side roller are driven roll。After steel plate is involved in from front offset roll, through multi-pass continuous bend, produce permanent plastic deformation, roll into required cylinder, cone cylinder or their part。The front offset roll of veneer reeling machine and rear side roller height can up-down adjustment, reach the curvature of requirement according to technological requirement。Middle lower roll changes the curvature of making sheet, have also been changed the centre-to-centre spacing of two side roller simultaneously along the change of arc trajectory, makes thin plate to skid。Steel plate is rolled onto the size of requirement, disconnects the clutch of front offset roll, rear side roller, middle lower roll, connects turning device clutch, switching mechanism is made to flip to the outside, nut in worm-gear speed reducer holds top roll by pull bar simultaneously, keeps the balance of top roll, the steel plate that removal is spooled。Secondary reductor reversion, turning device and top roll return to original position。
It is load unbalanced to there is working roll in existing four-roll plate bending machine, the weak point of roll bending inefficiency。
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, it is provided that a kind of four-roll plate bending machine。
The four-roll plate bending machine of the present invention, including tilting device, short stand arrangement, roll feeding device, two side roller devices, lower roller arrangement, high stand arrangement, bascule, hydraulic, hydraulic system and base, described roll feeding device, including support, fixing seat, the top roll being fixed between support and fixing seat, being connected in the tapered sleeve of upper roll end, be connected in bearing block in the middle part of top roll and shaft coupling, also include the pull bar being connected with fixing seat and the worm-gear speed reducer being connected with pull bar, described tapered sleeve is fixed on support。
It is provided with copper sheathing between described tapered sleeve and top roll, between described bearing block and top roll, is provided with copper sheathing。
Described shaft coupling is provided with dome head, and described shaft coupling is fixed on top roll by dome head and locknut。
The four-roll plate bending machine of the present invention, has the following technical effect that, working roll balancing the load, and roll bending efficiency is high。
Detailed description of the invention
The four-roll plate bending machine of the present invention, including tilting device, short stand arrangement, roll feeding device, two side roller devices, lower roller arrangement, high stand arrangement, bascule, hydraulic, hydraulic system and base, described roll feeding device, including support, fixing seat, the top roll being fixed between support and fixing seat, being connected in the tapered sleeve of upper roll end, be connected in bearing block in the middle part of top roll and shaft coupling, also include the pull bar being connected with fixing seat and the worm-gear speed reducer being connected with pull bar, described tapered sleeve is fixed on support。
It is provided with copper sheathing between described tapered sleeve and top roll, between described bearing block and top roll, is provided with copper sheathing。
Described shaft coupling is provided with dome head, and described shaft coupling is fixed on top roll by dome head and locknut。
