Abstract
The utility model discloses a kind of pressure-sensitive arrangements for speed regulation based on saw blade loss prevention, comprise power part, propulsive element and rotation cutting part, in hydraulic circuit in propulsive element, be provided with pressure inductor, power part is provided with rotational speed governor, and pressure inductor is connected with rotational speed governor.By pressure inductor, the force value in hydraulic circuit is transferred to rotational speed governor, reach the object of controlling the rotation cutting part fltting speeds such as saw blade.The utility model can effectively prevent that saw blade etc. from rotating cutting part and in cutting process, playing tooth damage, saves a large amount of saw blade costs, and can obtain considerable economic benefit.
Description
Technical field
The utility model relates to the damage-proof device on a kind of sawing machine, is specifically related to a kind of pressure-sensitive arrangements for speed regulation based on saw blade loss prevention.
Background technology
Cutting aluminium saw blade is conventional accessory and the consumable accessory of aluminium section bar manufacturer, the main cause of its damage is (by sawing material, to be all the aluminium extrusion base material that hardness is stable) when aluminium sawing amount is larger, and not timely corresponding the slowing down of saw blade fltting speed causes saw blade beat tooth and damage.
Existing apparatus is a tumbler, and saw blade rotates with the speed of 3000 revs/min, and another saw blade mobile device promotes saw blade to being moved with certain speed by saw thing, and material is sawed-off the most at last.Unscientific place is that mobile device speed can not be with being changed speed by the sawing difficulty of saw thing, if a material is very thick, saw blade is sawed constantly a little while, but it still advances by the initial speed of manually adjusting, rigidly push forward sawing, so just cause saw blade hard defects, destroy the alloy knife of inlaying in blade teeth.
Summary of the invention:
The utility model will solve the existing problem of above-mentioned background technology, provides a kind of pressure-sensitive arrangements for speed regulation based on saw blade loss prevention, excessive velocities while preventing sawed-off material, the loss that rigid extruding causes saw blade.
In order to solve the problems of the technologies described above the technical solution of the utility model, be: a kind of pressure-sensitive arrangements for speed regulation based on saw blade loss prevention, comprise power part, propulsive element and rotation cutting part, in hydraulic circuit in propulsive element, be provided with pressure inductor, power part is provided with rotational speed governor, and pressure inductor is connected with rotational speed governor.
Preferably, propulsive element comprises hydraulic pump, pressure regulator valve, pressure inductor and the hydraulic cylinder being connected in turn between power part and rotation cutting part.
Preferably, pressure inductor is arranged on hydraulic pump among pressure regulator valve arrives the hydraulic circuit of hydraulic cylinder.
Preferably, pressure regulator valve is manual pressure regulating valve.
Preferably, power part is motor.
Preferably, rotating cutting part is saw blade.
The utility model has added pressure inductor and rotational speed governor in the push structure of original sawing machine, by the pressure sensitive in propulsive element hydraulic circuit and by the force value sensing, wear vertical rotational speed governor, rotational speed governor exports the electric current of power part motor to by it, keep or reduce the rotating speed of motor or other power parts, thereby reach the object that reduces the rotation cutting part fltting speeds such as saw blade when force value is larger.The utility model can effectively prevent that saw blade etc. from rotating cutting part and in cutting process, playing tooth damage, saves a large amount of saw blade costs, and can obtain considerable economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment
In figure: 1, rotate cutting part 2, power part 3, hydraulic pump 4, pressure regulator valve 5, pressure inductor 6, hydraulic cylinder 7, rotational speed governor
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
A kind of pressure-sensitive arrangements for speed regulation based on saw blade loss prevention of the present utility model, comprise power part 2, propulsive element and rotation cutting part 1, and power part 2 is motor, and rotating cutting part 1 is saw blade.
Propulsive element comprises hydraulic pump 3, manual pressure regulating valve 4, pressure inductor 5 and the hydraulic cylinder 6 being connected in turn between power part 2 motors and rotation cutting part 1 saw blade, and pressure inductor 5 is arranged on hydraulic pump 3 among pressure regulator valve 4 arrives the hydraulic circuit of hydraulic cylinder 6.In hydraulic circuit in propulsive element, be provided with pressure inductor 5, power part 2 is provided with rotational speed governor 7, and pressure inductor 5 is connected with rotational speed governor 7.
The course of work of the present utility model is, by manual pressure regulating valve 4, set initial pressure value, start power part 2 motors, by propulsive element, promoting to rotate cutting part 1 saw blade advances, now, the pressure inductor 5 being arranged in push mechanism hydraulic circuit is delivered to rotational speed governor 7 by force value wherein, and then controls the velocity of rotation of power part 2 motors, and by propulsive element, reduces the pace of rotating cutting part 1 saw blade.Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
