Abstract
The utility model relates to a small portable moving type bow saw machine which mainly comprises an internal circulation closed type hydraulic system. Two hydraulic oil switches which are arranged at the front surface and the back surface of the saw machine are used for controlling two overflowing valves arranged on two return ducts. When material is stopped, the rising and the falling can be freely controlled, oil can not be leaked, and operating condition is clean. The pulling force of a speed rod is positioned at the same plane surface of a saw blade. The moment of couple is equal to 0. The cutting ability is enhanced, the service life of the saw blade is extended, the wrapping angle of a driving belt pulley is small, the transmission efficiency is high, an exposed type adjusting electric machine and the tension force of the belt of a driven belt pulley are adopted, and the adjustment is convenient.
Description
The utility model small portable portable hack saw machine belongs to a kind of interior circulation closed hydraulic pressure sawing machine.
Hacksawing machine is as dynamo-electric common apparatus, be widely used in all kinds of in, small enterprise, can be described as a kind of traditional plant equipment, adopt semiclosed circulation type liquid pressing system but present small-sized hydraulic hacksawing machine, leakage of oil easily, lathe is very unclean, and the oil circuit breaker operation is also convenient not to the utmost, during fracture, shelf can not be controlled rising, can only lift by hand, saw blade is stressed improper, fractures easily.
The purpose of this utility model just is to provide the small portable portable hack saw machine of circulation closed hydraulic pressure system in a kind of the employing, and to solve the hacksawing machine leakage of oil, the control shelf rises during fracture, and saw blade is in problems such as best stress in working order down.Improve working environment, the operating condition of hacksawing machine, enhance productivity.
According to above-mentioned design, the utility model small portable portable hack saw machine mainly is that a kind of interior circulation closed hydraulic pressure mechanism (5), shelf (4) and transmission system, cooling water system (15) are arranged.In this in circulation closed hydraulic pressure mechanism (5), two back oil roads have been offered between oil cylinder (23) and the fuel tank (27), and two overflow valves (25) and overflow valve (26) be set respectively on these two back oil roads, two overflow valves are promptly controlled by two the hydraulic oil switches (12) that are distributed in the lathe front and back, the variation of its overflow sectional area size, promptly control what of overflow oil mass, then realizing the control of cutter speed down.The saw blade clip slot center line and connecting rod (7) the wall thickness central lines of screw (16) turned round and tightened to saw on the shelf (4), guaranteed that saw blade tightens up the location after, saw blade and connecting rod (7) center of drag exists together in one plane, makes under the duty moment of couple=0.In transmission system, motor (21) is away from big belt pulley (17), so that small belt pulley (18) cornerite is little, improves transmission efficiency, and adopt outer naked formula to regulate the tension force of motor (21) and big belt pulley (17), overcome the inconvenience that general employing inner sealing formula is regulated motor and negative pulley wheel.
Compared with prior art, of the present utility model have a following major advantage:
1). owing to adopted interior circulation closed hydraulic pressure system, solved existing hacksawing machine and adopted the frequent leakage of oil problem of semi-enclosed circulation type liquid pressing system, the lathe very cleaning that seems.
2) can control the shelf lifting during fracture, easy to operate.
3) the connecting rod pulling force is realized the moment of couple=0 on the same plane of saw blade, has improved cutting ability, and saw blade also is not easy to damage.
4) motor is far away apart from negative pulley wheel, and the drive pulley cornerite is little, has improved transmission efficiency, and owing to adopt outer naked formula to regulate motor and negative pulley wheel belt tension, therefore adjusts also very convenient side.

Embodiment:
Press Fig. 2 transmission system and arrange, pinion (8) should to guarantee the initiatively less cornerite of travelling gear, improve transmission efficiency as far as possible away from big belt pulley (17).Plunger-type fuel pump eccentric wheel (19) and plunger water pump eccentric wheel (20) are installed on gear wheel (6) power transmission shaft.The installation of saw blade on shelf (4) turned round and the location of set screw (16) is regulated by saw, makes the connecting rod pulling force on the same plane of saw blade, reaches the moment of couple=0.Press Fig. 3, in hydraulic system structure, two oil return valves are set in two back oil roads particularly, these two oil return valves are controlled by again and are installed on two hydraulic oil switches of sawing machine front and back (12) respectively.
When sawing machine is started working, motor (21) rotation drives small belt pulley (18), imports big belt pulley (17) into through belt and passes to pinion (8) and pass to gear wheel (6) again and rotate the back and promote connecting rod (7) reciprocating sliding shelf (4) and finish sawing move (depth of cut size realizes by hydraulic system).
Make oil pressure go into oil cylinder (23) when gear wheel (6) drives its twisting eccentric wheel (19) when rotating counterclockwise by push rod plunger (22), make piston (push rod) (24) rising cutter lifting, make saw blade leave penetration of a cutting tool position, withdrawing.Fluid flows back to fuel tank (27) through overflow valve (25) or overflow valve (26) in the process that continues to dash forward, its overflow sectional area size, the following cutter speed of oil overflow what, realization.When gear wheel connecting rod Xiao axle went to the dead point, stroke had dashed, and continue to change and to surpass 60 when spending, push rod (plunger) (22) beginning motion oil pumping backward.And make sawtooth whereabouts contact workpiece, begin the post-tensioning sawing.Back and forth finish sawing motion journey.
When gear wheel (6) rotated, its axle also rotated eccentric wheel (20) reciprocating sliding plunger water pump plunger simultaneously, realized the cooling of start automatic water-supply, shut down and promptly cut off the water automatically.
Can if rise, can support the location back of a bow (3) by carrying-handle (11) by hydraulic oil switch control lifting behind the fracture, the moving pincers seats of operation (9), fixing pincers seats (10) and pincers seat screw mandrels (13) carry out discharging (or material loading) again.
