Abstract

Provided is a portable hydraulic cutter comprising a motor which is connected with the oil pressure pump through the end cover. The motor shaft is arranged with an eccentric wheel. A piston is installed in the pump body and is arranged with an oil hole and an oil cavity which is arranged with a pressure plate and an unloading plug. The piston contacts the eccentric wheel which is characterized in that the pressure plate is connected with the piston. The head of the piston is installed with a moveable knife. A spring is provided outside the piston. The other end of the pump body is connected with a still knife base. The head of the still knife base is arranged with a still knife. Both ends of the spring respectively contacts the still knife base and the pressure plate. A handle is installed on the motor shell and the pump body. The positions of the moveable knife and the still knife of the utility model cooperate tangentally. Therefore, the two knives cut off steel reinforcement in a shearing way without sparkles, which is very stable and fully safe and especially suitable to cut off a small amount of steel reinforcement in architecture as well as to cut off reinforcement in environments with fireproof requirement. The motor shell and the pump body are arranged with a handle that makes carrying convenient and flexible in use.

Description

Portable hydraulic pressure cutting machine

Technical field

The utility model relates to portable hydraulic pressure cutting machine, belongs to hardware ﹠ tools, is mainly used in the building cut-out to the house frame reinforcing bar.

Background technology

In the building of reinforced concrete building, for example dwelling house, office building etc., be to build up multilayer or high level mostly, and the reinforcing bar of multilayer or high-rise building frame structure has perpendicular (being equivalent to pillar) and horizontal (being equivalent to collar tie beam), vertical reinforcement is one one and passes through welding rising from the bottom up, transverse steel is to prolong through welding from one to the other end, reinforcing bar whenever ties one deck and just waters concrete, laterally each layer reinforcing bar is at head, vertical reinforcement arrives top often unnecessary length, need slice off unnecessary length.Prior art slices off the unnecessary reinforcing bar of head and adopts gas cutting, and speed is fast, is specially adapted under the situation that many reinforcing bars need cut off.Because the gas cutting set of tools is relatively heavy, carrying is inconvenient, when the reinforcing bar that cuts off only is several of decimals, and particularly one, two or three, four etc., if just pretty troublesome with gas cutting, and gas cutting has spark, poor stability.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, and providing a kind of is power with hydraulic pressure, reaches to cut off building reinforcing bar (φ is at 10-25mm) portable hydraulic pressure cutting machine easy to use, safe.

The technical scheme of the portable hydraulic pressure cutting machine of the utility model is: motor is arranged, motor connects the oil pressure pump pump housing through end cap, eccentric wheel is arranged on motor shaft, plunger is installed in the pump housing, and be shaped on oilhole and oil pocket, oil pocket has pressing plate and off-load plug, plunger contacts with eccentric wheel, it is characterized in that pressing plate connects piston, the head of piston is installed moving knife, and piston has spring outward, the other end of the pump housing links to each other with quiet tool rest, the head of quiet tool rest is installed quiet cutter, and two of spring contacts with quiet tool rest and pressing plate respectively, on the motor casing and the pump housing handle is installed.

Portable hydraulic pressure cutting machine of the present utility model, moving knife is tangent the cooperation with the position of quiet cutter, so cut off reinforcing bar by two edges of a knife, be that a kind of shearing is cut off, do not have spark, very steady, fool proof, be specially adapted to architecturally cut off the minority reinforcing bar, and have the place of fire protection requirement to cut off reinforcing bar.On the motor casing and the pump housing, handle is arranged, easy to carry during use, flexible.

Portable hydraulic pressure cutting machine of the present utility model, its motor has cooling fan blade and blade cover, and is overheated and damage when cooling fan blade is avoided machine operation, blade cover protection fan blade.Sealing push rod and spring are installed in the afterbody of its piston, and the other end of sealing push rod contacts with the off-load plug, withstands on off-load beyond the Great Wall.

Fig. 2 is the portable hydraulic pressure cutting machine of a utility model schematic top plan view;

Fig. 3 is that the eccentric wheel of the portable hydraulic pressure cutting machine of the utility model promotes the plunger schematic diagram.

The specific embodiment

The utility model relates to a kind of portable hydraulic pressure cutting machine, as Fig. 1, Fig. 2 and shown in Figure 3, motor 1 is arranged, motor 1 connects the oil pressure pump pump housing 12 through end cap 8, on 1 in motor, eccentric wheel 10 is arranged, plunger 9 is installed in the pump housing 12, and be shaped on oilhole 11 and oil pocket 26, oil pocket has pressing plate 25 and off-load plug 13, plunger 9 contacts with eccentric wheel 10, and its major technology is characterised in that pressing plate 25 connects piston 15, and the head of piston 15 is installed moving knife 16, piston has spring 24 outward, the other end of the pump housing 12 links to each other with quiet tool rest 14, and the head of quiet tool rest 14 is installed quiet cutter 17, and two of spring 24 contacts with quiet tool rest 14 and pressing plate 25 respectively, side at quiet tool rest 14 has separator tube 19 and buffering plug 18, and handle 3 is installed on the motor casing and the pump housing 12.When motor 1 work, the plunger 9 that eccentric wheel 10 on the motor shaft promotes in the pump housing, oil in the plunger handle oil cylinder is pressed into oil pocket 26 through oilhole 11, owing to overcoming spring 24 power, the increased pressure in the oil pocket 26 promotes pressing plate 25, pressing plate promotes piston (or being called the moving knife seat) 15, piston drives moving knife 16 and advances, because moving knife 16 is tangent cooperations with the position of quiet cutter 17, as shown in Figure 2, moving knife and quiet cutter be tangent line 5 mutually, so cut off reinforcing bar by two edges of a knife, be that a kind of shearing is cut off, there is not spark, very steady, fool proof, be specially adapted to architecturally cut off the minority reinforcing bar, and have the place of fire protection requirement to cut off reinforcing bar.On the motor casing and the pump housing, handle is arranged, easy to carry during use, flexible.After motor quits work, under the effect of spring 24 power, anti-push plate 25, off-load plug 13 is opened, and moving knife resets, end-of-job.Its motor 1 has cooling fan blade and blade cover 2, and is overheated and damage when cooling fan blade is avoided machine operation, and blade cover protection cooling fan blade avoids fan blade impaired.Sealing push rod 20 and spring 21 are installed in the afterbody of its piston 15, and the other end of sealing push rod 20 contacts with off-load plug 13, and off-load plug 13 is withstood.
