Description
Technical Field
The utility model relates to a press especially relates to a two liftout devices of press.
Background
The press machine is a device for processing a metal blank into a part by applying a strong pressure to the metal blank to plastically deform and break the metal, and generally includes steps of drawing, trimming, blanking, punching, and the like. And when the mould of press is closing the mould, some tensile parts are very easily by the stretch breaking or the surface is not up to standard, lead to the finished product qualification rate not high, consequently, buffer such as air cushion or cylinder all can be installed in the below of mesa to a lot of presses, make the part follow air cushion or cylinder slowly get off when stamping forming to the product that makes the punching press can reach fine surface requirement. In addition, after the part is stamped, the stamped part is extruded to be attached to a die and is difficult to take out, and in order to facilitate stripping, an ejection device is arranged below the table board of the press machine, and the part is ejected out through the ejection device, so that the part is rapidly stripped. However, in the existing press machine, the buffer device and the material ejecting device are two mutually independent components and are separately and independently installed below the table board of the press machine, the buffer device and the material ejecting device need to be controlled through two stations, a large installation space is needed below the press machine, and the structure of the press machine base is also complex.
Disclosure of Invention
The utility model aims to solve the technical problem that a two liftout devices of press are provided, the liftout effect after buffering stretching effect and part punching press when it has realized the part punching press through a station are accomplished has realized the control of integrating of press punching press buffering and liftout, and has saved installation space, makes in its press that can be used to the miniaturization, and the suitability is better.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: a double-ejection device of a press machine comprises at least one first cylinder and at least one second cylinder, wherein the first cylinder and the second cylinder are fixedly connected in a coaxial mode, the first cylinder or the second cylinder is fixed on the lower end face of a working table top of the press machine, a first piston is arranged in the first cylinder, the first piston is in sealing sliding fit with the first cylinder, a hollow piston rod is fixedly arranged on the first piston in a coaxial mode, the upper end of the hollow piston rod penetrates through the working table top, a top plate is fixedly arranged at the uppermost end of the hollow piston rod, a second piston is arranged in the second cylinder, the second piston is in sealing sliding fit with the second cylinder, a solid piston rod is fixedly arranged on the second piston in a coaxial mode, and the solid piston rod penetrates through the hollow piston rod, and the uppermost end of the solid piston rod is fixedly provided with a cushion block, the middle part of the top plate is provided with a through hole with the shape matched with that of the cushion block, so that the cushion block can penetrate through the through hole, and the first cylinder and the second cylinder are both provided with independent air inlet holes and air outlet holes.
Furthermore, the number of the first cylinders is at least two, the first cylinders are sequentially and coaxially and fixedly connected, and the hollow piston rods are sequentially and coaxially and fixedly connected.
Furthermore, the number of the second cylinders is at least two, the second cylinders are sequentially and coaxially and fixedly connected, and the solid piston rods are sequentially and coaxially and fixedly connected.
Compared with the prior art, the utility model has the advantages that this two liftout devices buffer when having realized the part punching press through a station and stretch and the liftout after the part punching press is accomplished, realized the control that integrates of press punching press buffering and liftout, and saved the installation space of press base, make it can be used to in the miniaturized press, adaptability is better, in addition, has also simplified the structure of base, the cost is reduced.
