Abstract
The utility model relates to a forging press mechanical device, particularly to a pneumatic air cushion device of which the stroke is manually regulated on a press machine, which belongs to the technical field of forging press mechanical devices. The device comprises a connecting plate. Guide seats are respectively fixed to the two sides of the connecting plate, guide posts of guide sleeves are arranged on the guide seats, and a cylinder of two ejector rods is fixed in the middle of the connecting plate. The lower ejector rod of the cylinder of two ejector rods is connected with an adjusting nut by threads, and a buffering pad is arranged on the adjusting nut. The upper ejector rod of the cylinder of two ejector rods is connected with an upper ejection plate by a connecting ball joint and a ball bowl. In the device, the resistance of an air cushion is counteracted by utilizing the characteristics that standard cylinders of two ejector rods can automatically move up and down when the work stroke of the press machine is reduced, and the collision force of the adjusting nut with the cylinder cover of the cylinder of two ejector rods is reduced under the action of the buffering pad. The service life of the cylinder of two ejector rods is extended.
Description
Technical field
The utility model relates to a kind of forging machinery and equipment, specifically relates to pneumatic type manual adjustments stroke air-cushion device on a kind of forcing press, belongs to the forging machinery and equipment technical field.
Background technology
The main application of forcing press air cushion is: when carrying out drawing work, be used for pushing down the edge of blank, in order to avoid produce wrinkle.Drawing, behind stamping-out or the extruding end-of-job, utilizing it from counterdie, to eject the workpiece of shaping, also can be used to workpiece is carried out local shaping processing.Purposes had enlarged after forcing press was installed air cushion, if be adjustable with the air cushion stroke alteration then that purposes enlarges is bigger, and needn't change push rod when mold exchange more, can adopt the standard push rod.So the use of the air cushion that stroke is adjustable on forcing press more and more widely.At present, the air cushion stroke control mechanism great majority of forcing press adopt and come transmission by motor by worm and gear, the worm gear endoporus has screw thread and screw rod screws, when worm gear rotates in positive and negative direction, screw rod moves up and down, so as to regulating the stroke of air cushion, the high-low limit position of stroke brushes up against travel switch with feeler lever and controls, and cost is higher.And when carrying out impulse stroke,, consume part energy owing to overcome the resistance of air cushion.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, a kind of pneumatic type manual adjustments stroke air-cushion device is provided, it includes connecting plate, the connecting plate both sides are fixed with guide holder respectively, the guide pillar that has guide pin bushing is arranged on the guide holder, and the connecting plate center fixed has Double Tops bar cylinder, on the lower push rod of Double Tops bar cylinder by the adjusting nut that has been threaded, cushion pad is arranged above the adjusting nut, and the upper ejector pin of Double Tops bar cylinder is connected with upper plate by connection bulb, ball bowl.When this device utilizes the Double Tops bar cylinder of standard can the characteristics that move up and down initiatively to reduce the forcing press impulse stroke, overcome the resistance of air cushion, utilize the effect of cushion pad, reduce the dynamics that the cylinder cap of adjusting nut and Double Tops bar cylinder is collided, prolonged the life-span of Double Tops bar cylinder.By regulating the mobile stroke that change Double Tops bar cylinder of adjusting nut on Double Tops bar cylinder lower push rod, promptly change the maximum of upper plate and lower connecting plate relative motion distance, realize the change of air cushion stroke.
The utility model is realized with following technical scheme: a kind of pneumatic type manual adjustments stroke air-cushion device, it is characterized in that: it includes connecting plate, the connecting plate both sides are fixed with guide holder respectively, the guide pillar that has guide pin bushing is arranged on the guide holder, the connecting plate center fixed has Double Tops bar cylinder, the lower push rod of Double Tops bar cylinder has cushion pad by the adjusting nut that has been threaded above the adjusting nut, the upper ejector pin of Double Tops bar cylinder is connected with upper plate by connection bulb, ball bowl.
The both sides of described connecting plate are fixed with guide holder respectively, and the guide pillar that has guide pin bushing is arranged on the guide holder, and the guide pillar top is fixed with upper plate.
Be fixed with ball-head cover on the described upper plate.
The utility model has the advantages that: when this device utilizes the Double Tops bar cylinder of standard can the characteristics that move up and down initiatively to reduce the forcing press impulse stroke, overcome the resistance of air cushion, utilize the effect of cushion pad, reduce the dynamics that the cylinder cap of adjusting nut and Double Tops bar cylinder is collided, prolonged the life-span of Double Tops bar cylinder.By regulating the mobile stroke that change Double Tops bar cylinder of adjusting nut on Double Tops bar cylinder lower push rod, promptly change the maximum of upper plate and lower connecting plate relative motion distance, realize the change of air cushion stroke.
