Description
Technical field
A kind of bar cropper is the utility model is related to, more particularly to a kind of hydraulic mechanism of bar cropper.
Background technology
Bar cropper is a kind of instrument used in a kind of shear reinforcement.It is general to have full-automatic reinforcing bar cutting machine, and half
Point of automatic steel bar shears.It is one of essential equipment of steel bar meter, and it is mainly used in building construction, bridge, tunnel
To the customized cut-off of reinforcing bar in the engineerings such as road, power station, large-scale water conservancy.Bar cropper has weight compared with other cut-out equipment
Amount is light, power consumption less, reliable operation, efficiency high the features such as, therefore be progressively machined in recent years with bar mill etc. extensively
Using played an important role in the every field of the development of the national economy.With the continuous development of industry, the difficulty of reinforcing bar cutting
Spend increasing, weight and security for bar cropper are it is also proposed that higher requirement；Reinforcing bar used in the country at present
Still the problems such as overall dimensions are larger, weight is larger, security is not high, service life is short be present in cutting machine.
The content of the invention
The purpose of this utility model is solve the deficiencies in the prior art, the utility model provide it is a kind of it is simple in construction,
The hydraulic mechanism of bar cropper reasonable in design, overall dimensions are smaller, in light weight, service life is long, maintenance and repair cost is low.
Technical scheme is used by the utility model solves its technical problem：A kind of hydraulic mechanism of bar cropper,
Including casing, motor, the downside of the casing is provided with fuel tank, and the piston with motor linkage, the piston are provided with the casing
The pump housing is provided between casing, oil cylinder is additionally provided with the casing, the cylinder cavity is connected with pump housing inner chamber, the piston
Piston spring, oil pressure shut-off switch, oil pressure shut-off switch spring, switch oil sealing cap are provided with the pump housing and the oil cylinder place of being connected between the pump housing,
The oil cylinder is provided with head frame away from casing side, is provided with cutting axis in the oil cylinder, the head end of the cutting axis extends to a frame
It is interior and relative to head frame slide.
Preferably, the tail end of the cutting axis is provided with oil sealing towards oil cylinder side, the outer sheath of the cutting axis is provided with
Spring, the tail end of the both ends of the spring respectively with head frame, cutting axis abut against.
Preferably, the pump housing is process by 42CrMo materials, the piston is process by Cr12MoV, described
Oil cylinder is process by 7075-T6 aluminium alloys.
The utility model the utility model is designed using oil cylinder, pump housing split, solves oil cylinder, pump housing integral structure
The problem of overall dimensions are big, weight weight, and the replacement cost of oil cylinder, the pump housing is also reduced, the utility model also has structure letter
The advantages that single, reasonable in design.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made further specifically
It is bright.
