Abstract
A constant-scissoring-force scissor type scissoring head comprises a fixed scissoring arm (1) and a movable scissoring arm (2). The movable scissoring arm (2) and the fixed scissoring arm (1) are combined to form a hinge pair by the aid of a rotating pin (3). The constant-scissoring-force scissor type scissoring head is characterized by further comprising a gear pair, an oil cylinder (12) and a framework (5), the gear pair consists of a fan-shaped gear ring (8) and a rack (10), the oil cylinder (12) provides driving power, the fixed scissoring arm (1) is fixed onto a brace strut (7) of the framework (5), a driving arm end of the movable scissoring arm (2) is fixed onto the fan-shaped gear ring (8), a guide rail (14) is mounted on the top of the framework (5), a slider is disposed on the guide rail (14), a piston rod of the driving oil cylinder (12) is fixed onto the framework (5), a cylinder body of the oil cylinder (12) is fixed onto the slider (15), and the lower portion of the slider (15) is fixedly connected with the rack (10). The constant-scissoring-force scissor type scissoring head can provide constant scissoring force, and guarantees that the scissoring force is unchanged during an integral scissoring procedure of an optional scissoring point of a scissoring mouth.
Description
Technical field
The utility model relates to a kind of shearing equipment, especially the cutting edge scissor-type cutting head that shearing force is all constant everywhere.
Background technology
At present, general scissor-type cutting head is to utilize laborsaving lever principle (power arm length is greater than shearing the arm of force) to change the shearing force of cutting (pincers) head.In the course of the work, because power arm or effective active force are continually varyings, thereby the shearing force that causes the arbitrary shearing point on the haircut cutting edge also is a continually varying, the rule that generally all is by from big to small (or from small to large) changes, and the excursion of maximum shear stress and minimum shearing force is bigger, can't the meet the demands instructions for use of the constant shearing force of shearing point of this cutting nippers head, simultaneously dwindled the dimension of object scope that is sheared, the power of drive source is not fully utilized in other words yet.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the invariable scissor-type cutting head of shearing force in the process of shearing of a certain shearing point on a kind of cutting edge is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of constant shearing force scissor-type cutting head, it comprises cuts arm and the moving arm of cutting surely, move and cut arm and cut arm surely by hinges of rotational pin composition, it also comprises gear pair, the oil cylinder that driving force is provided and the frame that fan-shaped gear ring and tooth bar are formed, described cutting surely on the strut that arm is fixed on described frame; The described moving actuating arm end of cutting arm is fixed on the described fan-shaped gear ring; The top of frame is equipped with guide rail, and described guide rail is provided with slide block; The piston rod that drives oil cylinder is fixed on the frame, and the cylinder body that drives oil cylinder is fixed on the slide block, fixedlys connected with described tooth bar in the bottom of slide block.
The described moving hinged place of cutting arm and cutting arm surely is provided with pad.
The beneficial effects of the utility model are:
The constant shearing force scissor-type of the utility model cutting head, constant shearing force can be provided, the arbitrary shearing point that guarantees the cutting edge mouth keeps shearing force constant in whole shear history, and can enlarge the scope of shear openings size, make full use of the power of drive source, energy savings, raise the efficiency, simultaneously, mechanism's compactness can reduce the volume and the quality of whole haircut.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Among the figure: cut arm 1 surely, move and cut arm 2, rotational pin 3, locking nut 4, frame 5, set bolt 6, strut 7, fan-shaped gear ring 8, bolt 9, tooth bar 10, bolt 11 drives oil cylinder 12, bolt 13, guide rail 14, slide block 15, pad 16.
The specific embodiment
Below in conjunction with accompanying drawing 1 and Fig. 2 the utility model is further specified.
The utility model relates to a kind of constant shearing force scissor-type cutting head, mainly by cutting arm 1 surely, and the moving arm 2 of cutting, the gear pair that fan-shaped gear ring 8 and tooth bar 10 are formed provides the oil cylinder 12 of driving force and critical pieces such as frame 5 that the top is equipped with guide rail 14 to form.Moving cut arm 2 and cut arm 1 surely and form a hinges by rotational pin 3, be placed with pad 16 between the arm 1 moving to cut arm 2 and cut surely, rotational pin 3 is outside equipped with locking nut 4, and the effect of locking nut 4 is to prevent that rotational pin 3 from coming off; Surely cutting arm 1 is fixed on the strut 7 of frame 5 by set bolt 6; The moving actuating arm end of cutting arm 2 is linked together by one a group of bolt 9 and a fan-shaped gear ring 8; The top of frame 5 is connecting guide rail 14 by one group of bolt 13; The piston rod that drives oil cylinder 12 is fixed on the frame 5, and cylinder body 12 is welded on the slide block 15, and the bottom of slide block is connecting a toothed rack 10 by one group of bolt 11.The power of drive source is that the mode by gear pair passes to the moving arm of cutting, guide rail and the secondary mode that adopts T type groove of slide block movement, and the moving arm drive end of cutting is the tongue-and-groove connection with connecting of fan-shaped gear ring, and locks with bolt.Described tooth bar is that tenon-groove connects with connecting of slide block, and locks with bolt.When driving oil cylinder 12 moved to right, oil cylinder 12 drove tooth bars 10 and moves right, and makes fan-shaped gear ring 8 clockwise directions rotation by gear pair, thereby the moving arm of cutting of haircut is opened; At this moment can be put on the shear blade being cut object, oil cylinder is sheared being cut object to left movement.
Claims (2)
1. constant shearing force scissor-type cutting head, it comprises cuts arm (1) and the moving arm (2) of cutting surely, move and cut arm (2) and cut arm (1) surely by hinges of rotational pin (3) composition, it is characterized in that: it also comprises gear pair, the oil cylinder (12) that driving force is provided and the frame (5) that fan-shaped gear ring (8) and tooth bar (10) are formed, described cutting surely on the strut (7) that arm (1) is fixed on described frame (5); The described moving actuating arm end of cutting arm (2) is fixed on the described fan-shaped gear ring (8); The top of described frame (5) is equipped with guide rail (14), and described guide rail (14) is provided with slide block (15); The piston rod of described driving oil cylinder (12) is fixed on the frame (5), and described driving oil cylinder (12) cylinder body is fixed on the slide block (15), fixedlys connected with described tooth bar (10) in the bottom of described slide block (15).
2. a kind of constant shearing force scissor-type cutting head according to claim 1 is characterized in that: the described moving hinged place of cutting arm (2) and cutting arm (1) surely is provided with pad (16).
