Abstract
The utility model discloses rotary shaft reinforcement stresses and eliminate machine, it comprises frame, bearing block, bearing, power transmission shaft, resistance to emery wheel and bearing block fixed head, described bearing block is connected with frame by bearing block fixed head, bearing is arranged in bearing block, bearing inner race installs power transmission shaft, and the square head portion of power transmission shaft front end is connected with resistance to emery wheel.The rotary shaft reinforcement stresses that the utility model proposes eliminates machine, bending wheel is directly installed on axle, or directly just axle one end can be made into wheel directly to push down reinforcing bar and bend, the bending radius of this mode reinforcing bar in theory can be unlimited reduce, reach desirable stress elimination effect, and structural design is more simple, dismounting is keeped in repair, it is all convenient to change wheel.
Description
Technical field
The utility model relates to stress eliminating device in a kind of reinforcing steel bar production line, and particularly rotary shaft reinforcement stresses eliminates machine, is especially applicable to the reinforcing bar that equipment adaptive capacity is 5mm-12mm.
Background technology
Reinforcing bar product is in cold-drawn, because internal crystal framework is subject to external force in the process such as cold rolling, its inner generation internal stress, and internal stress can have influence on the performance of product, tradition reinforcing bar stress elimination mode is taken turns by stress elimination to make reinforcing bar alternating bending in process of production, and discharge internal stress, bending radius its bending degree less of reinforcing bar is larger, it is better that internal stress is eliminated, what conventional apparatus adopted is that axle is fixed, bending wheel turns, also rolling bearing to be installed in the middle of wheel and axle, want to reduce bar bending radius, only has reduction wheel diameter, bearing just must be caused to diminish, depression of bearing force, faults frequent, strengthen bearing and also just increase wheel radius, also bar bending radius is just added, stress elimination deleterious, and examine and replace is pretty troublesome, the stress elimination of stress eliminating device by this way to reinforcing bar have certain restriction, and equipment failure rate is higher, maintenance difficult.
Summary of the invention
Technical problem to be solved in the utility model is to provide rotary shaft reinforcement stresses and eliminates machine, bending wheel is directly installed on axle, or directly just axle one end can be made into wheel directly to push down reinforcing bar and bend, the bending radius of this mode reinforcing bar in theory can be unlimited reduce, reach desirable stress elimination effect, and structural design is more simple, dismounting is keeped in repair, it is all convenient to change wheel.
For realizing above-mentioned technical purpose, the utility model rotary shaft reinforcement stresses eliminates machine, it comprises frame, bearing block, bearing, power transmission shaft, resistance to emery wheel and bearing block fixed head, described bearing block is connected with frame by bearing block fixed head, bearing is arranged in bearing block, described bearing is heavy-duty bearing and arranges multiple row, spaced apart by bearing spacer between every two row heavy-duty bearings.Bearing inner race installs power transmission shaft, and the square head portion of power transmission shaft front end is connected with the square opening of resistance to emery wheel.The front end of power transmission shaft also can become one with resistance to emery wheel; Square opening is connected with and is beneficial to resistance to emery wheel disassembling, assembling and replacing fast, and one connection can make the radius of resistance to emery wheel less, and stress elimination effect is better.
Bearing block realizes moving up and down by the location of two bearing block fixed heads in frame slot, realizes reinforcing bar in various degree bending, reach the object of desirable elimination reinforcing bar internal stress by the relative position change between movable pulley and fast pulley.
The rotary shaft reinforcement stresses that the utility model proposes eliminates machine, bending wheel is directly installed on axle, or directly just axle one end can be made into wheel directly to push down reinforcing bar and bend, the bending radius of this mode reinforcing bar in theory can be unlimited reduce, reach desirable stress elimination effect, and structural design is more simple, dismounting is keeped in repair, it is all convenient to change wheel.

Detailed description of the invention
See accompanying drawing 1, in background technology, rotary-type reinforcement stresses is eliminated machine and is comprised frame 1, bending wheel 2, axle 3 and bearing 4, what adopt is that axle is fixed, bending wheel turns, also rolling bearing to be installed in the middle of wheel and axle, want to reduce bar bending radius, only has reduction wheel diameter, bearing just must be caused to diminish, depression of bearing force, faults frequent, strengthen bearing and also just increase wheel radius, also bar bending radius is just added, stress elimination deleterious, and examine and replace is pretty troublesome, the stress elimination of stress eliminating device by this way to reinforcing bar have certain restriction, and equipment failure rate is higher, maintenance difficult.
See accompanying drawing 2,3, rotary shaft reinforcement stresses eliminates machine, it comprises frame 5, bearing block 6, bearing 7, power transmission shaft 9, resistance to emery wheel 11 and bearing block fixed head 12, described bearing block is connected with frame by bearing block fixed head, bearing is arranged in bearing block, described bearing is heavy-duty bearing and arranges multiple row, spaced apart by bearing spacer 8 between every two row heavy-duty bearings.Bearing inner race installs power transmission shaft, and the square head portion of power transmission shaft front end is connected with resistance to emery wheel.
Described power transmission shaft front end is connected with resistance to emery wheel one or power transmission shaft front end arranges square head portion and is connected with the square opening of resistance to emery wheel, is compressed by axle head gland 10; Square opening is connected with and is beneficial to resistance to emery wheel disassembling, assembling and replacing fast, and one connection can make the radius of resistance to emery wheel less, and stress elimination effect is better.
Bearing block realizes moving up and down by the location of two bearing block fixed heads in frame slot, realizes reinforcing bar in various degree bending, reach the object of desirable elimination reinforcing bar internal stress by the relative position change between movable pulley and fast pulley.
The rotary shaft reinforcement stresses that the utility model proposes eliminates machine, bending wheel is directly installed on axle, or directly just axle one end can be made into wheel directly to push down reinforcing bar and bend, the bending radius of this mode reinforcing bar in theory can be unlimited reduce, reach desirable stress elimination effect, and structural design is more simple, dismounting is keeped in repair, it is all convenient to change wheel.
