Abstract

The utility model relates to a single shear mechanism used for shearing a bus, which comprises an upper scissor guiding seat and a lower scissor mechanism which are fixedly connected to a rack, wherein a gap allowing a workpiece to be sheared to pass is formed between the upper scissor guiding seat and the lower scissor mechanism; an upper scissor mechanism matched with the lower scissor mechanism is movably arranged in a vertical through hole of the upper scissor guiding seat; a swaging spring is arranged in an inside cavity of an upper scissor base of the upper scissor mechanism; a lower end penetrates movably out of the upper end of a swaging rod positioned opposite to lower scissors and at the bottom of the upper scissor base, and is fixedly connected with the lower end of the swaging spring; a return spring is arranged inside each side of the upper scissor base; the lower end of each return spring is fixedly connected with a release link abutted against the upper scissor guiding seat; and the top of the upper scissor base is abutted against the lower end of a piston rod which is fixedly connected with an actuating cylinder on a portal. The single shear mechanism is reasonable in structural design and convenient to use, and no waste material is not generated during shearing, so that the cost is saved.

Description

A kind of for the simple shear mechanism that shears bus

Technical field:

The utility model relates to a kind of for the simple shear mechanism that shears bus.

Background technology:

Existing numerical control bus-bar punching and shearing machine is whenever cut a cutter owing to adopt the punching mode, produces the long waste material of 5mm～8mm simultaneously, will produce a large amount of waste materials for the very short bus (length equals to arrange wide basically) of processing overlap joint row like this, causes waste.

The utility model content:

It is a kind of for the simple shear mechanism that shears bus that the utility model provides, and its reasonable in design, easy to use does not produce waste material during shearing, saved cost, has solved problems of the prior art.

The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: it comprises last scissors guide holder and the lower scissors mechanism that is connected in up and down on the frame, between last scissors guide holder and lower scissors mechanism, be provided with the slit that can pass through for workpiece to be cut, in the vertical through hole of last scissors guide holder, be movably equipped with match with lower scissors mechanism on shear mechanism; Described lower scissors mechanism comprises the lower scissors seat that is connected on the frame, is provided with lower scissors in the position of the corresponding through hole of a side of lower scissors seat and is positioned at the following pad of cutting below the lower scissors; The described shear mechanism of going up comprises the last scissors seat that is actively plugged in the through hole, the bottom of last scissors seat be provided with match with lower scissors on scissors, in the internal cavities of last scissors seat, be provided with a binder spring, upper end and binder spring lower end that one lower end activity passes the scissors seat bottom compressing rod relative with the lower scissors position are connected, inside, both sides at last scissors seat is respectively equipped with a back-moving spring, the lower end of each back-moving spring all is fixed with a release link that connects with last scissors guide holder, and the top of last scissors seat and the piston-rod lower end that is fixed with the actuating cylinder on the door frame connect.

The utility model adopts such scheme, and reasonable in design, easy to use does not produce waste material during shearing, saved cost.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Fig. 2 for of the present utility model go up the scissors guide holder and on see the structural representation of mechanism.

Among the figure, 1, frame, 2, go up the scissors guide holder, 3, lower scissors mechanism, 31, the lower scissors seat, 32, lower scissors, 33, cut pad down, 4, go up shear mechanism, 41, go up the scissors seat, 42, binder spring, 43, compressing rod, 44, go up scissors, 45, back-moving spring, 46, release link, 5, actuating cylinder, 6, piston rod, 7, door frame, 8, workpiece to be cut.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

As Fig. 1～shown in Figure 2, the utility model comprises last scissors guide holder 2 and the lower scissors mechanism 3 that is connected in up and down on the frame 1, between last scissors guide holder 2 and lower scissors mechanism 3, be provided with the slit that can pass through for workpiece to be cut, in the vertical through hole of last scissors guide holder 2, be movably equipped with match with lower scissors mechanism 3 on shear mechanism 4.Lower scissors mechanism 3 comprises the lower scissors seat 31 that is connected on the frame 1, is provided with lower scissors 32 in the position of the corresponding through hole of a side of lower scissors seat 31 and is positioned at the following pad 33 of cutting below the lower scissors 32.Last shear mechanism 4 comprises the last scissors seat 41 that is actively plugged in the through hole, the bottom of last scissors seat 41 be provided with match with lower scissors 32 on scissors 44, in the internal cavities of last scissors seat 41, be provided with a binder spring 42, upper end and binder spring 42 lower ends that one lower end activity passes the scissors seat 41 bottoms compressing rod 43 relative with lower scissors 32 positions are connected, be respectively equipped with a back-moving spring 45 in the inside, both sides of last scissors seat 41, the lower end of each back-moving spring 45 all is fixed with a release link 46 that connects with last scissors guide holder 2, and the top of last scissors seat 41 and piston rod 6 lower ends that are fixed with the actuating cylinder 5 on the door frame 7 connect.

During use, to wait to cut workpiece 8 earlier is put on the upper surface of lower scissors seat 31 and lower scissors 32 by the slit between last scissors guide holder 2 and the lower scissors mechanism 3, adjust clipped position, the staff controls actuating cylinder 5 actions then, the piston rod 6 of actuating cylinder 5 promotes to go up scissors seat 41 and descends, move down thereby drive compressing rod 43 and last scissors 44, compressing rod 43 is pushed down earlier and is waited to cut workpiece 8 and be located, and lower scissors 32 cooperates with last scissors 44 and will wait to cut workpiece 8 and cut off then.The staff controls actuating cylinder 5 action and resets then, and last scissors seat 41 rises under the effect of release link 46 and back-moving spring 45 and resets, and drives scissors 44 and compressing rod 43 simultaneously and resets, and waits pending shearing next time.The utility model adopts such scheme, and reasonable in design, easy to use does not produce waste material during shearing, saved cost.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
