Description
Technical field
The utility model belongs to reinforcing steel bar hoop bending equipment technical field, particularly relates to a kind of haulage gear of hoop bender.
Background technology
As everyone knows, hoop bender distraction procedure is drawn wheels and traction wheels and contact roller assembly by power drive and is closed the reach realizing reinforcing bar.But it is not firm, unstable to there will be contact roller clamping force in existing hoop bender use procedure, causes reinforcing bar cannot move ahead because tractive force is not enough or moves ahead continuously, traction function was lost efficacy.In addition, existing its drive part of hoop bender haulage gear is motor and reductor, wherein the clutch end of reductor is direct-connected with traction power shaft, and this drive mechanism in use exists following defect: 1, slowly, power attenuation is large for high speed start-stop and rotating response speed; 2, reductor often breaks down, and service life is low, adds maintenance and use cost.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provide a kind of high speed start-stop and rotating fast response time and registration, overall performance is reliable, long service life, can realize the haulage gear of continuous seepage, hoop bender that efficiency is high.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Design a kind of haulage gear of hoop bender, comprise the parallel compression wheels be equipped with and traction wheels and bearing thereof up and down, the traction input shaft end at the initiative traction wheel place of described traction wheels is connected with synchronous belt drive mechanism, each contact roller corresponding is respectively equipped with a set of hold-down mechanism, this hold-down mechanism comprises arm, wherein be hinged in the middle part of arm and compress on wheels bearing, one end of arm is provided with pressure head, this pressure head is connected with contact roller rotating shaft through bearing, the other end of arm is External Force Acting end, the position of described External Force Acting end power is greater than the length of position to pin joint vertical line of pressure head end power to the length of pin joint vertical line.
Described synchronous belt drive mechanism comprises traction power mechanism, is arranged on the driven pulley of traction input shaft end, with the driving pulley that be arranged on traction power mechanism output shaft of this driven pulley by toothed belt transmission.
Described traction power mechanism is traction electric machine.
The External Force Acting end of described arm is vertically equipped with cylinder or hydraulic jack, wherein cylinder or hydraulic jack tailpiece of the piston rod by joint and arm hinged.
Described pressure head and arm are integral type structure.
The beneficial effect of technical solutions of the utility model is:
Existing drive mechanism adopts toothed belt transmission to replace by the haulage gear of the utility model hoop bender, and overall weight is light, and rotary inertia is little, reliable transmission, steadily, high speed start-stop and rotating fast response time, and power attenuation is little; Failure rate is low, long service life, maintenance and use cost is low, contributes to realizing continuous seepage, enhances productivity.And toothed belt transmission declines to a great extent relative to existing structure noise, easy to maintenance.
In addition, the utility model utilizes arm principle, structure is simple and laborsaving, each contact roller corresponding is respectively equipped with a set of hold-down mechanism, can ensure to apply reliable, continual and steady active force to contact roller, and then guarantee that tractive force enough drives reinforcing bar to move ahead or move ahead continuously, to realizing consecutive production, enhancing productivity further and playing positive role.
