Abstract

The invention provides a novel pneumatic friction V-shaped plate shearing machine. The pneumatic friction V-shaped plate shearing machine comprises a motor, a motor wheel, a triangular belt, a flywheel, a pneumatic friction clutch brake, a rotary connector, a speed reducer, a coupler, a main shaft system, an upper knife rest, a lower knife rest and a quick blade interval adjusting system. The motor wheel drives the flywheel to run through the triangular belt, air close disconnection and ventilation tight connection are achieved through the pneumatic friction clutch brake, a drive load shaft transmits the coupler on the speed reducer to rotate a main shaft, and an eccentric chain bar pushes the lower knife rest to move linearly upwards to be matched with the upper knife rest to achieve the shearing purpose. The pneumatic friction V-shaped plate shearing machine has the advantages that the blade interval can be quickly adjusted; three-point type supporting idler wheel non-interval sliding is adopted in the lower knife rest, friction force is small, and abrasion is small; by the adoption of speed reducer and coupler transmission, the structure is compact, noise is lowered, and operation is stable; the clutch and braking functions can be achieved through a novel friction disc; boards are sheared symmetrically through V-shaped blades and unilateral offset is avoided.

Description

Pneumatic friction V-type plate shearing machine

Art:

The present invention relates to a kind of new plate shears trigger, i.e. Pneumatic friction V-type plate shearing machine.

Background technology:

At present, on market the main plate shearing machine used be Q12, Q11 hydraulic plate shears, Q11 mechanical shear trigger and Q11DK electrical control plate shearing machine three major types type, be main product selected during client produces, hydraulic plate shears easy oil leakage, shear rate is slow, seal is fragile, and it is more difficult to keep in repair, and mechanical shear trigger noise is large, easily wear and tear in clutch position, maintenance difficult, electrical control plate shearing machine frequent starting, causes spread of voltage.

Summary of the invention:

The object of the invention is to: a kind of new Pneumatic friction V-type plate shearing machine is provided, structurally have employed one-level V belt translation, flywheel, air operated friction clutch, reductor and coupling driving gear, motor wheel on motor drives flywheel running by V-belt, worked by air operated reversing valve via air operated friction clutch, when holding one's breath, flywheel has built-in bearing to keep idle running storage power, during ventilation, frictional disk fits, at this moment acting is driven by flywheel inertia reserve, by reductor through shaft joint drive shaft, through eccentric wheel, the cutter that chain bar promotes lower slide bottom knife and upper tool post realizes shearing object.

The present invention is achieved in that a kind of new Pneumatic friction V-type plate shearing machine, comprising: motor, motor wheel, V-belt; Flywheel is driving force deposit force piece; Pneumatic friction dish is clutch and brake part; Reductor is reduction of speed functor; Main shaft, eccentric wheel, connecting rod are stroke traction element; Upper tool post, cutter, lower slide, bottom knife, left and right sidesing wall plate are for running cutter body component; Pressing plate seat associated group component is binder parts; Lower support roller, front support roller, upper support regulate roller to run and gap blade adjustment functional part for ensureing upper tool post, it is characterized in that: the motor wheel on motor drives flywheel running by V-belt, swivel joint air inlet is had to fit frictional disk, drive the motion of reductor reduction of speed, via shaft joint twisting main shaft, the cutter of the bottom knife and upper tool post that at this moment promote lower slide by the raw stroke of the round and smooth movable property of the connecting rod on eccentric wheel realizes shearing function.

Technical scheme of the present invention is: the deposit of shearing force is carried out in the running of motor rotation motor wheel driving triangular belt traction flywheel, and Pneumatic friction dish carries out closed braking by exhaust, and work (braking is simultaneously opened) is fited in air inlet; Reductor realizes reduction of speed increase torsion and exports, and drives eccentric wheel to rotate, round and smooth dynamic through compound sleeve, and drivening rod promotion lower slide does the motion of upper and lower lock formula, uses, thus reach shearing function with upper tool post blades fit.

The invention has the beneficial effects as follows:

The first: adopt air operated friction clutch to have hard and soft, overcome traditional mechanical type clutch rigidity shortcoming; It two is: upper tool post adopts bikini support roller gapless to slide, and frictional force is little, weares and teares little; It three is: gap blade can be adjusted soon; It four is: adopt reductor, shaft joint, and compact conformation reduces noise smooth running; It five is: adopt new-type friction plate can reach clutch and braking dual-use function; It six is: select V-type blade symmetry to shear sheet material not single-side shift.

Detailed description of the invention:

Embodiment: at Fig. 1, Fig. 2, Fig. 3, in Fig. 4, motor (1) is worked by air operated reversing valve by flywheel (3) and air operated friction clutch (4) through one-level V belt translation, flywheel (3) idle running when holding one's breath, during ventilation, frictional disk fits, at this moment done work via driving off-load axle (13) by flywheel (3) inertia reserve, rotate the synchronous drive shaft (14) of reductor (5) shaft joint (6) chain (7), via eccentric wheel (18), connecting rod (19) promotes lower slide (24) bottom knife (23) and realizes shearing object with the cutter (22) of upper tool post (21).

Experiment proves

Advantage of the present invention: the first: adopt air operated friction clutch to have hard and soft, overcome traditional mechanical type clutch rigidity shortcoming, the shortcoming that clutch structure parts are more, easy to wear, noise is large; It two is: adopt reductor to reduce volume, deducted the large pinion of traditional mechanical plate shearing machine; It three is: adopt and support that roller ensures upper tool post sliding and running, runs decrease frictional force more greatly than traditional plane and straight line, enhances upper tool post sliding surface service life; It four is: regulate the corresponding adjustment of roller lazy-tongs by upper support, can rapid adjustment gap blade; It five is: adopting V-type blade symmetry to shear can ensure by shear material not to single-side shift.
