Description
Technical field
The utility model relates to a kind of punch press, particularly a kind of punch press that is used for air-conditioner fin production.
Background technology
At present, air-conditioner fin extensively adopts impact style production, need to process some holes on the air-conditioner fin, can adopt in the prior art that single step is advanced, two stepping and multistep advance mode and process, so-called single step is advanced, be meant slider of punch hole of punching press in single stroke, two steppings are meant slider of punch two holes of punching press in single stroke range, and multistep enters then to be meant slider of punch a plurality of holes of punching press in single stroke range.For producing the air-conditioner fin of different hole counts, need between different steppings, change, advancing to change multistep as single step advances, two steppings change that single steps are advanced etc., a kind of air-conditioner fin punch press feeding conversion equipment is arranged at present, comprise the eccentric wheel that eccentric throw is adjustable, eccentric eccentric position is hinged with pull bar, the pull bar other end is socketed between two limited steps on the sliding axle, be provided with thrust unit between tie rod end and the step, sliding axle and a connection piece fix, and are fixed with the power transmission shaft perpendicular to sliding axle on the connector, are fixed with the rocking bar perpendicular to power transmission shaft on the power transmission shaft, rocking bar connects a feed appliance, and the power transmission shaft two ends are connected on the location-plate by bearing.During use, location-plate is fixed on the fuselage of punch press, simultaneously, eccentric wheel is fixed on the output shaft of punch press bent axle, when bent axle rotates, the pushing drawing rod swing, pull bar promotes output shaft through sliding bar and comes and goes rotation, and output shaft drives the rocking bar swing, and rocking bar drives feed appliance and realizes feeding; The adjustment of feeding stroke can realize by regulating eccentric eccentric throw; In the crank up one of punch press during week, the feeding stroke of different steppings is inconsistent, the conversion of stepping can realize by the relative position that adjustment tie rod end and sliding axle are topped bar, when tie rod end lays respectively at two steps, one side, the distance of pull bar and power transmission shaft is unequal, promptly changed the radius of gyration, thereby, can realize the stepping conversion as long as push pull bar to another step from a step, can realize that by changing distance between two steps stepping changes two steppings, a stepping etc. is changeed in two steppings; But in practice, it is not in place that we find that this stepping conversion regime of the prior art usually can stepping occur, and tie rod end is jam on sliding axle easily, and it is smooth and easy inadequately to move, and the impact during conversion is also big, causes disorderly step phenomenon easily, and the punching press plate is scrapped.Therefore, though air-conditioner fin punch press feeding conversion equipment of the prior art is simple in structure, its poor reliability.
The utility model content
The purpose of this utility model provides a kind of air-conditioner fin punch press feeding conversion equipment that overcomes above-mentioned defective, make its can be between variant stepping smooth conversion, conversion is impacted little, reliable.
The purpose of this utility model is achieved in that a kind of air-conditioner fin punch press feeding conversion equipment, comprises eccentric wheel and power transmission shaft that eccentric throw is adjustable, and eccentric eccentric position is hinged with pull bar; Be fixed with the rocking bar perpendicular to power transmission shaft on the power transmission shaft, the power transmission shaft two ends are by on the bearing connected positioning plate; The lower end of pull bar is hinged with a quadric chain, described quadric chain comprises and is hinged to tetragonal left connecting rod, intermediate connecting rod, right connecting rod and lower link successively, pull bar and left connecting rod and intermediate connecting rod are hinged, the pin joint of left side connecting rod and lower link is arranged on the location-plate, the hinged curved rod in the end of intermediate connecting rod, described curved rod middle part is hinged with location-plate, curved rod is provided with at least two pairs of directive wheels, clamping has arc-shaped guide rail between the directive wheel, arc-shaped guide rail is fixed on the drive plate, and drive plate center and power transmission shaft fix; The lower link downside is provided with a cylinder, the connector that the piston direction of motion of cylinder is provided with movable plate and is hinged with lower link, the movable plate downside is provided with cushion block, the movable plate upside is provided with the upper ejector pin that is axially perpendicular to movable plate, relative fixed has at least one to adjust backing plate on the location-plate, and described upper ejector pin is fixed therein one and adjusts on the backing plate.
During the utility model work, the output of the bent axle of eccentric wheel and punch press is fixed, and location-plate and punch press fuselage fixed, simultaneously the feed appliance of rocking bar with the mould upside is connected, when the punch press bent axle rotated, eccentric wheel drove the pull bar motion, pull bar drives the curved rod swing through quadric chain, curved rod drives the arc-shaped guide rail swing, and arc-shaped guide rail is through drive plate and the swing of power transmission shaft drive rocker, and then the feeding of driving feed appliance.The adjusting of feeding stroke can realize by the eccentric position of adjusting yoke and eccentric pin joint, by above-mentioned transmission the amplitude of fluctuation of rocking bar is changed, and then feed appliance feeding stroke is changed; In the work, the conversion of stepping realizes by cylinder moving, when the piston in the cylinder is in lower dead point position, the movable plate place abuts on the cushion block, the angle that this moment, intermediate connecting rod and arc-shaped guide rail formed is bigger, during crank up, the amplitude that curved rod promotes the curved rod motion is also big, and the stroke that rocking bar drives the feed appliance feeding is also big; When the piston in the cylinder is in upper dead center position, movable plate abuts in the upper ejector pin bottom, the angle that this moment, intermediate connecting rod and arc-shaped guide rail formed is less, the amplitude that curved rod promotes the curved rod motion is also little, the stroke of rocking bar driving feed appliance feeding is also less, change thereby under stopped status not, also can be implemented between two different strokes, realized that promptly punch press changes between two different steppings; The relative position that the purpose of adjusting backing plate is to change upper ejector pin bottom and cushion block is set; also promptly changed the displacement of movable plate; thereby, when shutting down, regulate, can change set stepping translative mode by changing thickness or the quantity of adjusting backing plate.The utility model can be between variant stepping smooth conversion, conversion is impacted little, reliable, step mode changes convenient; Can be applicable on the processing punch press of porous stamping parts, be specially adapted to the production of air-conditioner fin.
As further improvement of the utility model, described connector is provided with lower push rod, and lower push rod axis top is provided with a buffer, and buffer is fixed on to be adjusted on the backing plate.When carrying out the stepping conversion, movable plate is up, at first contacts with buffer unit, contacts with upper ejector pin after buffering again, thereby makes the impact of stepping conversion littler.
Impact when changing for further reducing stepping, the upper surface and the lower surface of described movable plate are provided with cushion pad.
