Abstract
The invention discloses a self-contained air cushion of a mechanical press. The self-contained air cushion of the mechanical press comprises an air cushion top plate (1), guide rods (2), a piston (3), an inner air cylinder barrel (4), an air cylinder press cover (7), a vent hole (8), an air cylinder flange (9) and an air inlet II (10). The guide rods, the inner air cylinder barrel and the air cylinder press cover are installed on the air cylinder flange. The vent hole is formed in the air cylinder press cover. The air inlet II is formed in the inner air cylinder barrel. The piston is installed inside the inner air cylinder barrel. The piston is connected with the air cushion top plate through a piston rod of the piston. The self-contained air cushion of the mechanical press further comprises an outer air cylinder barrel (5) which is also installed on the air cylinder flange. A cavity is formed by the outer air cylinder barrel and the inner air cylinder barrel. An air inlet I (6) is formed on the lower portion of the outer air cylinder barrel. According to the self-contained air cushion, working effects of externally connecting with air bags are achieved by adding of the outer air cylinder barrel, the separated air bags are changed to be an air cylinder form integrated with the mechanical press, and pits dug for the external connecting air bags are omitted. The self-contained air cushion of the mechanical press is compact in structure and convenient to install and maintain. Equipment occupied space is reduced, and equipment cost is reduced.
Description
Technical field
The present invention relates to a kind of forcing press, particularly a kind of punching machine self-tolerant air cushion.。
Background technology
Press air cushion also known as stretching pad, be widely used in suppress on large pressing machine heavy parts or
deeplydraw
stretchpart, stretch pad except be used for stretch time flanging prevent wrinkling except, also can be used as liftout or do bottom workpiece locally-shaped.Forcing press just can expand the purposes scope of forcing press after the pad that stretches is housed, such as has the UP function of the pad that stretches to carry out darker drawing work.
At present, common punching machine air cushion and forcing press are separated from each other, and during installation, need to dig melt pit and place gas bag, especially when required air cushion power is larger, occupation area of equipment is large, and installation procedure is complicated, and the problem that cost is higher is particularly outstanding.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of punching machine self-tolerant air cushion, this air cushion becomes to be integrated with forcing press, does not need separately to connect gas bag, reduces floor space, compact conformation, easy for installation, reduces costs.
To achieve these goals, the technical solution adopted in the utility model is: a kind of punching machine self-tolerant air cushion, comprise air cushion top board, guide post, piston, inside cylinder cylinder, cylinder gland, steam vent, cylinder flange and air inlet II, cylinder flange is provided with guide post, inside cylinder cylinder and cylinder gland, cylinder gland has steam vent, inside cylinder cylinder has air inlet II, piston is contained in inside cylinder cylinder, piston is connected with air cushion top board by its piston rod, also comprise outside cylinder cylinder and air inlet I, described outside cylinder cylinder is also arranged on cylinder flange, and form cavity with inside cylinder cylinder, the bottom of outside cylinder cylinder has air inlet I.
The cavity volume that inside cylinder cylinder and outside cylinder cylinder are formed is 4 times of swept volume needed for it, enough meets air cushion job requirement.
The diameter of air inlet II is greater than the diameter of air inlet I.
This self-tolerant air cushion is by increasing outside cylinder cylinder, reach the working effect of external gas bag, its maximum feature the gas bag of separation is changed into the cylinder form with forcing press one, and do not need separately to connect gas bag, eliminate the melt pit for external gas bag digs, not only compact conformation, installation and maintenance are convenient, reduce occupation area of equipment, and greatly reduce equipment cost.In addition, the purposes of this self-tolerant air cushion is also quite extensive, and it is not only applicable to punching machine, is also applicable to the occasion that other plant equipment need to increase by air cushion itself volume.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, air cushion top board, 2, guide post, 3, piston, 4, inside cylinder cylinder, 5, outside cylinder cylinder, 6, air inlet I, 7, cylinder gland, 8, steam vent, 9, cylinder flange, 10, air inlet II.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, this punching machine self-tolerant air cushion, comprise air cushion top board 1, guide post 2, piston 3, inside cylinder cylinder 4, cylinder gland 7, steam vent 8, cylinder flange 9 and air inlet II 10, cylinder flange 9 is provided with guide post 2, inside cylinder cylinder 4 and cylinder gland 7, cylinder gland 7 has steam vent 8, inside cylinder cylinder 4 has air inlet II 10, piston 3 is contained in inside cylinder cylinder 4, piston 3 is connected with air cushion top board 1 by its piston rod, also comprise outside cylinder cylinder 5, described outside cylinder cylinder 5 is also arranged on cylinder flange 9, and form cavity with inside cylinder cylinder 4, the bottom of outside cylinder cylinder 5 has air inlet I 6.
The cavity volume that inside cylinder cylinder 4 and outside cylinder cylinder 5 are formed is not less than 4 times of swept volume needed for it, enough meet air cushion job requirement, like this, when needs larger air cushion power or larger air cushion stroke, this cavity also can adapt to the needs of swept volume preferably.
The diameter of air inlet II 10 is greater than the diameter of air inlet I 6, is beneficial to as piston 3 provides sufficient operation power.
Guide post 2, cylinder gland 7, inside cylinder cylinder 4 and outside cylinder cylinder 5 are fixedly mounted on cylinder flange 9 according to order from top to bottom, from the inside to surface successively, then this self-tolerant air cushion self installs substantially, again by the air inlet I 6 of outside cylinder cylinder 5 lower end access air compressor machine, and be provided with pressure valve at air inlet I 6 place, according to the size of required air cushion power, the input pressure of adjustments of gas can be carried out.
During work, air compressor machine is by sending into the gas setting certain pressure endlessly in air inlet I 6 outwards cylinder barrel 5, because inside cylinder cylinder 4 is placed among the cavity of outside cylinder cylinder 5, therefore the air with pressure enters in inside cylinder cylinder 4 along the air inlet II 10 on inside cylinder cylinder 4, then promote the piston 3 be arranged in inside cylinder cylinder 4 to move up and down, air cushion top board 1 moves up and down under the drive of piston 3, completes the work such as locally-shaped bottom flanging, liftout or workpiece.
The gas bag of separation is changed into the cylinder form with forcing press one by this punching machine self-tolerant air cushion, eliminates the melt pit for external gas bag digs, not only compact conformation, and installation and maintenance are convenient, reduce occupation area of equipment, and greatly reduce equipment cost.
