Description
Technical field
This utility model relates to the technical field of steel bar meter, specifically one reinforcing bar first time cold drawn length photo-electric control mechanism.
Background technology
The making of cold drawn bar, it is necessary to twice cold drawing process.When first time is cold drawn, making the internal tension of reinforcing bar exceed its yield point, design tension stress, and reach requirement cold-drawn rods, maintenance sheds load after slightly stopping.
" concrete structure engineering construction quality accident specification " specifies in 5.3.3 bar and explanation: bar straightening should adopt mechanical means, it is possible to adopts cold drawn method.When adopting cold drawn method straightening reinforcing bar, the cold-drawn rods of HPB235 level reinforcing bar is not preferably greater than 4%, and the cold-drawn rods of HRB335 level, HRB400 level and RRB400 level reinforcing bar is not preferably greater than 1%.
In practical operation, it is typically all and controls cold-drawn rods by control of percentage elongation after reinforcing bar retrial is qualified, in prior art, cold drawn bar elongation control method is: weld place's pointer on cold drawn bar, cold drawn groove arranges scale, by manual observation, reach specific bit postpone stopping cold drawn.Owing to the collimation error, pointer rock and the signal transmission reason such as not in time, cold drawn length inaccuracy, error is for being generally ± 5cm.Adopt the reinforcing bar totally 150 that this method is cold drawn, rupture 6, cause certain former material waste, and create corresponding potential safety hazard.
Chinese patent, Full-automatic steel bar mfg. machine (application number: 95106257.3) discloses a kind of steel bar meter machine possessing cold drawn function, including computer control system, hydraulically powered cold drawn feeding, brake forming, cutting system, photoelectric measuring length counting, angular transducer etc..This technical scheme attempts to control steel bar cold-drawn by computer, it is apparent that technical scheme is not made the detailed design of comparison by utility model people, this patent is finally also without obtaining corresponding mandate.
Utility model content
A kind of reinforcing bar first time cold drawn length photo-electric control mechanism, including hoist engine and control structure, hoist engine drives cold drawn bar by assembly pulley, described control structure includes photoelectric controller, along opening catalyst, inverse opening catalyst and reflective paster, described hoist engine is respectively through opening catalyst be connected with photoelectric controller with inverse along opening catalyst, and described reflective paster is arranged on cold drawn bar.
Described photoelectric controller includes transformator, scattered reflection type photoswitch and control contactor, and scattered reflection type photoswitch is connected with transformator, control contactor respectively.
This utility model has the advantage that and includes, without manual observation and safety custody, saving labour turnover with good effect；Cold drawn length is unified, and error control is in mm rank；The saving time, improve work efficiency；Adopting safe voltage, electric shock risk is low；Reduce the probability of cold drawn bar fracture to a certain extent, security risk and former material saving are had certain help；Simple in construction, system cost is low.
Accompanying drawing explanation
Fig. 1 is the circuit connection diagram of this utility model reinforcing bar first time cold drawn length photo-electric control mechanism.
Number in the figure illustrates as follows: 1, hoist engine；2, along opening catalyst；3, against opening catalyst；4, transformator；5, scattered reflection type photoswitch；6, control contactor.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme is illustrated.
Working background: cold drawn bar model is HRB400 Φ 25mm, design tension stress is for being not less than 500MPa.The making of cold drawn bar, it is necessary to twice cold drawing process.When first time is cold drawn, making the internal tension of reinforcing bar exceed its yield point (400N/mm2), design tension stress (500MPa), and reach requirement cold-drawn rods, maintenance sheds load after slightly stopping.
Conceptual design: selected 5 tons of hoist engines coordinate 8 times of assembly pulleys, carries out cold drawn for the first time in cold drawn groove, cold drawn one every time, joint length 62m, and controlling elongation is 2.17m(cold-drawn rods 3.5%).
A kind of reinforcing bar first time cold drawn length photo-electric control mechanism, including hoist engine 1 and control structure, hoist engine drives cold drawn bar by assembly pulley, described control structure includes photoelectric controller, along opening catalyst 2, inverse opening catalyst 3 and reflective paster, described hoist engine 1 is respectively through opening catalyst 3 be connected with photoelectric controller with inverse along opening catalyst 2, and described reflective paster is arranged on cold drawn bar；Described photoelectric controller includes transformator 4, scattered reflection type photoswitch 5 and control contactor 6, and scattered reflection type photoswitch 5 is connected with transformator 4, control contactor 6 respectively.
Before system comes into operation, first adjust cold draw rod positions, along starting hoist engine, when arriving the cold drawn position required, reflection plaster paper is arranged on cold drawn bar and its reflective surface is corresponding with the photosurface of photoelectric controller；
Cold drawn bar is playbacked, when along, when starting hoist engine, powering along opening catalyst adhesive, motor, along starting, affects cold drawn bar by assembly pulley, until reflective paster moves to the position corresponding with photoelectric controller；
The photosensitive rear close point action of photoelectric controller, control contactor power-off, motor shuts down, and now two cold drawn spacing are 64.17m, completes the cold drawn work required；
Inverse startup hoist engine, powers against opening catalyst adhesive, and motor is inverse to be started, and controls cold drawn bar and returns to correct position.
When large-scale continuous production deformed bar, also native system can be optimized further, as:
1, implement warning linkage, during operation hoist engine, alarm can be sent, remind non-operator to leave cold drawn region；
2, increase time switch, photoswitch, it is possible to automatically control the stress retention time after cold drawn completing, be then automatically releasable to specifying position.
The above, it it is only preferred embodiment of the present utility model, not this utility model is done any pro forma restriction, although this utility model is with preferred embodiment openly as above, but, it is not limited to this utility model, any those skilled in the art, without departing within the scope of technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solutions of the utility model, any simple modification above example made according to technical spirit of the present utility model, equivalent variations and modification, belong in the scope of technical solutions of the utility model.
