Abstract
The utility model relates to a hydraulic shear device for reinforced bars and steel stranded wires. In particular the utility model is adaptable for the field of anchor line of the steel stranded wires used to support the down-hole tunnel of a coal mine. The utility model employs the structure of a tubular stationary blade and a cylinder-and-piston moveable blade capable of moving along the axial direction of the tubular stationary blade to overcome the shortcomings of short service life and difficult restoration which results from the single-blade form of the existing shear device. The stationary blade and the moveable blade are respectively and fixedly connected with a hydraulic cylinder body and a cylinder rod. A back-moving spring is disposed between the cylinder rod and the hydraulic cylinder body. The tubular stationary blade is provided with four through-holes along radial direction. The utility model has the advantages of simple structure, long service life, easy fabrication and manufacture, easy maintenance and convenient utilization.
Description
The utility model relates to a kind of hydraulic clipper, is specially adapted to cut off reinforcing bar or steel strand wires.
At present, China is at the scene of used steel strand wires anchor cable during roadway support under the scene, particularly coal mine of using the steel strand wires anchor cable, in the time must exposing the steel strand wires anchor cable long part and cut away, cause can't adopt methods such as flame cutting or toothless saw cutting to block, and can only use clipper to shear.Existing clipper is in-line single-blade mouth (similar shaping machine) form, its complex structure, and working life is short, and cutting edge is in case damage is repaired very difficult.
In order to overcome above defective, the purpose of this utility model is to provide a kind of hydraulic clipper that is used for reinforcing bar, steel strand wires, has double blade, and is easy to processing and fabricating and reparation.
Technical solution of the present utility model is: this hydraulic clipper that is used for reinforcing bar, steel strand wires, have the fixed blade of tubular and be arranged at wherein and plunger type active blade movably vertically, fixed blade is fixedlyed connected with piston rod with hydraulic cylinder respectively with active blade; Between plunger rod and hydraulic cylinder, be provided with back-moving spring; Be positioned at and radially be provided with through hole on the tubular fixed blade.
Radial direction through hole on the fixed blade is 4, and is vertical mutually corresponding, and wherein two adjacent through-holes are slotted holes, and all the other are circular hole.The major axis of described slotted hole is to be provided with vertically, and its aperture length should be 2 times of Circularhole diameter.
The end face of active blade is concavity, preferably forms the acute angle of α=75 °-85 ° with the peripheral face of cylinder.
The utility model has the advantages that self-evident.At first be simple in structure, and double blade is than the obvious long working life of the clipper of single-blade mouth; And adopt columnar fixed blade and be located at its interior cylindrical active blade structure combining form, both be easy to processing and manufacturing and maintenance, use also more convenient.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A cross section view among Fig. 1.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
As shown in Figure 1 and Figure 2, this hydraulic clipper that is used for reinforcing bar, steel strand wires has the fixed blade 1 of tubular and is arranged at wherein and plunger type active blade 4 movably vertically, and fixed blade 1 is fixedlyed connected with piston rod 3 with hydraulic cylinder 6 respectively with active blade 4.Between plunger rod 3 and hydraulic cylinder 6, be provided with back-moving spring 5; Be positioned at and radially be provided with 4 through holes on the tubular fixed blade 1, vertical mutually corresponding, and wherein two adjacent through-holes are slotted holes, all the other are circular hole.The major axis of above-mentioned slotted hole is provided with vertically, and its aperture length should be 2 times of Circularhole diameter.The end face of active blade 4 is concavity, preferably forms the acute angle of α=75 °-85 ° with the peripheral face of cylinder, and thus no matter where active blade 4 is in, the acute angle of its end can both form shearing edge with the circular hole on the fixed blade 1.When using this device, reinforcing bar or steel strand wires anchor cable are inserted circular hole, hydraulic oil enters hydraulic cylinder by joint 2 and promotes piston rod 3, and then releases active blade 4 and promptly reinforcing bar, steel strand wires anchor cable are cut off; After the hydraulic cylinder unloading, under the effect of back-moving spring 5, piston rod 3 and active blade 4 can return to the home position.
