Abstract
The invention relates to a novel bidirectional air cushion structure of a pressure machine. An upper piston cavity and a lower piston cavity are arranged on the upper surface of a cylinder body; the cylinder body can be a whole body or is assembled by independent split bodies; a channel a and a channel b are arranged on the cylinder body so that the lower spaces of pistons are communicated; a channel c and a channel d are arranged at an appropriate position of the cylinder body so that upper cavities of the pistons are communicated; the upper piston and the lower piston are respectively arranged at a specified position, piston rods are correctly arranged on the upper piston and the lower piston, and a corresponding airway port is provided with a piston lower cavity air inlet and outlet connector, a piston upper cavity air inlet and outlet connector, a cylinder cover, and the like; and the combination parts and the mutual moving parts of the parts need to be reliably sealed.
Description
Technical field
The present invention relates to a kind of structure of forcing press air cushion, particularly a kind of structure of novel press machine bidirectional air cushion.Belong to the metal forming machinery technical field.
Background technology
Air cushion is the critical function parts of forcing press, and its effect is: withdraw from workpiece or waste material in the production process of forcing press, play the effect of retainer and binder from counterdie in the stretching operation.In all these operations, the direction of the active force of air cushion all is unidirectional, and just: air cushion has only the mode of action of the roof pressure that makes progress all the time on structural design, its mode of action is in the roof pressure state all the time just as a spring.Continuous development along with Tool and Die Technology, and some technologies change accordingly, not only need the roof pressure action function be arranged air cushion in more current punching production, also require it to have the function of tension and compression simultaneously, so the air cushion of present single effect is the needs of incompatibility technology development.
Summary of the invention
The objective of the invention is to: the structure that a kind of novel press machine bidirectional air cushion is provided, this air cushion is compared with traditional air cushion, not only has bigger active force, a kind of structure of novel press machine bidirectional air cushion that has the two-way function of roof pressure and tension and compression simultaneously is to adapt to the development need of present Sheet Metal Forming Technology.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of structure of novel press machine bidirectional air cushion, adopt double cylinder version, promptly, on a cylinder body, be separated out bilevel cylinder, lay independently piston rod in each cylinder, the strength that is obtained on the piston rod like this, be two piston acting in conjunction power and.In cylinder body appropriate location on one's body, make corresponding linked hole, the function of cylinder is up and down linked up.
Its operation principle structure is: make two-layer plunger shaft up and down on cylinder body, in above-mentioned cylinder body, it can be an integral body, also can be that independently split combines, open walk a, b are communicated with the lower part of piston space on the body of cylinder body, in the appropriate location of cylinder body, open walk c, d link the epicoele of piston; Lower piston and upper piston are placed certain location respectively, and piston rod is properly installed on lower piston and the upper piston, at corresponding air flue port piston cavity of resorption intake and exhaust joint and piston upper chamber intake and exhaust joint are installed, load onto cylinder cover etc., reliable sealing should be arranged in above-mentioned part junction and motion part mutually.
Beneficial effect: the present invention is owing to adopt double-piston jointly to the mode of the piston rod application of force, and by corresponding UNICOM pipeline is set, and cylinder all can be worked.So air cushion of the present invention not only active force is big, and have two-way function, can adapt to punching process, and the demand of Tool and Die Technology development.
Description of drawings
Accompanying drawing is a schematic diagram of the present invention.
Shown in the figure: 1, lower piston; 2, upper piston; 3, piston rod; 4, cylinder body; 5, piston cavity of resorption intake and exhaust joint; 6, piston upper chamber intake and exhaust joint.
The specific embodiment
On cylinder body (4), make two-layer plunger shaft up and down, in above-mentioned cylinder body (4), it can be an integral body, also can be that independently split combines, open walk a, b are communicated with the lower part of piston space on the body of cylinder body (4), appropriate location in cylinder body (4), open walk c, d link the epicoele of piston; Lower piston (1) and upper piston (2) are placed certain location respectively, and piston rod (3) is properly installed on lower piston (1) and the upper piston (2), at corresponding air flue port piston cavity of resorption intake and exhaust joints (5) and piston upper chamber intake and exhaust joint (6) are installed, load onto cylinder cover etc., reliable sealing should be arranged in above-mentioned part junction and motion part mutually.
Claims (2)
1. the structure of a novel press machine bidirectional air cushion, it is characterized in that: on cylinder body (4), make two-layer plunger shaft up and down, in above-mentioned cylinder body (4), it can be an integral body, also can be that independently split combines, open walk a, b are communicated with the lower part of piston space on the body of cylinder body (4), the appropriate location in cylinder body (4), and open walk c, d link the epicoele of piston.
2. the structure of a kind of novel press machine bidirectional air cushion according to claim 1, it is characterized in that: lower piston (1) and upper piston (2) are placed certain location respectively, and piston rod (3) is properly installed on lower piston (1) and the upper piston (2), at corresponding air flue port piston cavity of resorption intake and exhaust joints (5) and piston upper chamber intake and exhaust joint (6) are installed, load onto cylinder cover etc., reliable sealing should be arranged in above-mentioned part junction and motion part mutually.
