Description
Technical field
The utility model relates to a kind of enclosed bar cutting machine structure, and particularly material supporting mechanism cut by a kind of enclosed bar shears, belongs to technical field of forging and pressing equipment.
Background technology
In recent years along with the develop rapidly of automobile, aerospace, agricultural, operating theater instruments and hand-held tool industry, forging parts required precision is more and more higher, therefore to the cross section quality of the blank of part blanking and monnolithic case dimensional requirement also along with raising.Precision rod cutter is the technology accuracy product of electromechanical integration.Obvious superiority is had compared with similar shearing equipment with the Outstanding Quality of its high-quality, high-performance, high efficiency, material-saving, energy-conserving and environment-protective.
In the many employings of current domestic bar shears, bottom knife open type shears the method for bar, when gap blade adjustment is suitable, the bar cross section quality sheared is low, there is comparatively high inclination-angle, be difficult to meet not high-accuracy forging requirement, if accurate close forging adopts this shearing bar, need the follow-up process comparatively loaded down with trivial details to shear surface, not only waste material, also need to drop into artificial in a large number, cause the rising of manufacturing cost, shear bar blank dimension and the accuracy of form and position to improve and improve shearing area quality, industry facts have proved through a large amount of, in employing, bottom knife enclosed is sheared, can effectively improve tangent plane quality, meet high-accuracy forging requirement.Enclosed shearing work principle is different from open type and shears, when enclosed is sheared, bar is sheared part and is held tightly by cutter and lower support mechanism, avoids former bar naturally to tilt during shearing, therefore can improve and shears bar blank dimension and the accuracy of form and position and improve shearing area quality.This cut mode adopts special mould supporting, special supporting seat is configured with below bar, in shear history, supporting seat is to whole bar generation support force upwards, to ensure the cross section quality sheared, the bar supporting seat of current closed shears is in whole shear history, all produce support force upwards, supporting seat support force is about about 30% to 50% of required sheared blank power, the clean shearing force needed during sheared blank is certain, clean shearing force deducts the support force upwards that supporting mechanism provides for shearing force that cutting mechanism provides, in shear history, support force is deposited in case, reach the required clean shearing force needs of bar, the overall power of precision rod cutter must be improved, cause the higher of higher energy resource consumption and Equipments Setting.
Utility model content
Bar supporting seat support force all produced upwards in whole shear history that the purpose of this utility model is to overcome current closed shears causes the higher problem of higher energy resource consumption and Equipments Setting, provides a kind of enclosed bar shears to cut material method for supporting and supporting mechanism.
For realizing the purpose of this utility model, the technical scheme that the utility model adopts is: material supporting mechanism cut by enclosed bar shears, comprise bar supporting seat, described supporting seat is fixedly installed on vertical support body, described vertical support body sidewall is provided with at least two relative side wall inclined planes, described side wall inclined plane direction is: side wall inclined plane and horizontal line from side wall inclined plane bottom to direction outside sidewall between angle be acute angle, at vertical support body sidewall inclined-plane place, correspondence is provided with at least two relative clamp arms, described clamp arm front end is provided with the inclined-plane paralleled with supporter side wall inclined plane, clamp arm is connected with clamping force bringing device, supporter bottom is connected with reset drives device, further, described side wall inclined plane and horizontal line from side wall inclined plane bottom to direction outside sidewall between angle be 55-75 degree, further, described side wall inclined plane and horizontal line from side wall inclined plane bottom to direction outside sidewall between angle be 65 degree, further, the clamping force bringing device that described clamp arm connects is clamping cylinder, the reset drives device that supporter bottom connects is drawback cylinder.
Positive Advantageous Effects of the present utility model is: the utility model only applies support force in shearing bar process in initial certain stroke, support force is not had in remaining stroke, so there is no support force in about 80% stroke sheared, support force for zero when bar needed for clean shearing force diminish after the power output of cutting mechanism can be made greatly to reduce, so adopt the plant capacity consumption required for this method for supporting and configuration all can reduce, cost can be effectively reduced, and through facts have proved, method of the present utility model is identical with the cross section quality of sustainable existence support force in whole shear history with the shearing area quality of mechanism, meet the relevant criterion requirement that enclosed is sheared completely.Adopt inclined-plane rigid contact to provide support the mode of power in supporting mechanism provided by the utility model, compression and decompression support force is convenient to be controlled, and easily realize, flexible movements are reliable, adopt this supporting mechanism can realize method for supporting of the present utility model preferably.Namely the utility model ensure that the quality of enclosed shearing area, achieves again the reduction of energy consumption and cost, achieve purpose less than technique effect and huge business success.
