Abstract

The utility model relates to a manually operated hydraulic reinforcing bar cutter which is a machine for cutting reinforcing bars. The utility model is mainly composed of a cutting working head, a cylinder body, a piston, a spring, a pump valve body and a handle. The handle is repeatedly pressed, the pressure oil in the pump valve body continuously pushes a piston rod forward, and a reinforcing bar is cut under the action of a fixed and a movable knives. The utility model has the advantages of simple and compact structure, no requirement of external power during work, easy operation and labor saving, and widely is used for cutting and processing various reinforcing bars.

Description

Manually-operated hydraulic reinforcing bar cutter

The utility model is a kind of equipment of shear reinforcement, belongs to the technical field of building machinery.

Bar cutting machinery is pressed power form difference can be divided into manually (manpower) and motor-driven two kinds.General hand cutting machine is by mechanical booster mechanism shear reinforcement, its operation labour intensity is big, operating efficiency is low, and process very difficulty of large diameter reinforcing bar, and existing motor-driven (machinery or hydraulic pressure) bar cropper, because volume is big, carrying inconvenience, under some working environment, uses and be subjected to certain restriction again, do not having to carry out work under the situation of power source especially.

The purpose of this utility model provides a kind of bar cropper that carries out work with manpower.

Bar cropper of the present utility model mainly is made up of cut-out working head (1), cylinder body (2), pump valve body (3), piston rod (4), spring (5), handle (6).Wherein cylinder body (2) is arranged on and cuts off between working head (1), the pump valve body (3), connects with both are fastening, piston rod (4), spring (5) are set in the cylinder body (2), and handle (6) is hinged on pump valve body (3).

Adopt bar cropper of the present utility model, its advantage is: it has taken into account manual and hydraulicdriven characteristics, does not need the external world that power is provided during work, no energy consumption, noiselessness, easy and simple to handle, it is laborsaving to work, and volume is little, and is in light weight, can adapt to different working environments.

Accompanying drawing 1 is a structural representation of the present utility model.

Bar cropper embodiment of the present utility model is as follows:

Piston rod (4), spring (5) is contained in the cylinder body (2), shearing work head (1), pump valve body (3), fastening being linked together of cylinder body (2), on cut-out working head (1), stationary knife (1-1) is housed, moving knife (4-1) is housed on piston rod (4), fixed, moving knife (1-1), (4-1), be fastened on respectively and cut off on working head (1) and the piston rod (4), in pump valve body (3), be provided with oil-in (3-1), oil return opening (3-2), also be provided with oil return handle (3-3), valve piston (3-4) and other control valve, valve piston (3-4) are hinged with handle (6) again.The operation principle of this machine and the course of work are: at first reinforcing bar (7) is placed on and decides between the moving knife, press handle repeatedly, pressure oil constantly enters cylinder body from oil-in, overcomes spring pressure forward thereby promote piston rod, under the effect of fixed, moving knife with bar cutting.Unclamp the oil return handle, piston rod returns under spring action, finishes the one action circulation.According to the above, just can be made into hand Hydraulic Steel Bar Shear described in the utility model.

Claims

1, hand Hydraulic Steel Bar Shear, it is characterized in that cutting machine mainly forms by cutting off working head (1), cylinder body (2), pump valve body (3), piston rod (4), spring (5), handle (6), wherein cylinder body (2) is arranged on and cuts off between working head (1), the pump valve body (3), connect with both are fastening, piston rod (4), spring (5) are set in the cylinder body (2), and handle (6) is hinged on pump valve body (3).

2, hand Hydraulic Steel Bar Shear according to claim 1, it is characterized in that on cut-out working head (1), stationary knife (1-1) being housed, moving knife (4-1) is housed on piston rod (4), moving knife (1-1), (4-1) calmly,, be fastened on respectively and cut off on working head (1) and the piston rod (4), in pump valve body (3), be provided with oil-in (3-1), oil return opening (3-2), also be provided with oil return handle (3-3), valve piston (3-4), and other control valve, valve piston (3-4) is hinged with handle (6) again.
