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, concrete is a kind of punching machine self-tolerant air cushion.。
Background technology
The press air cushion pad that claims again to stretch, be widely used on large pressing machine the compacting heavy parts or
DeeplyDraw
StretchPart, the flanging that stretches pad when being used for stretching prevent wrinkling, also can be used as liftout or do the workpiece bottom locally-shaped.After forcing press is equipped with the pad that stretches, just can enlarge the purposes scope of forcing press, for example have the UP function of the pad that stretches to carry out darker stretching 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, and especially when required air cushion power was larger, occupation area of equipment was large, and installation procedure is complicated, and the problem that cost is higher is particularly outstanding.
Summary of the invention
Problem for above-mentioned prior art exists the invention provides a kind of punching machine self-tolerant air cushion, and this air cushion and forcing press become one, and do not need separately to connect gas bag, reduce floor space, and compact conformation is 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 the air cushion top board, guide post, piston, the inside cylinder cylinder, the cylinder gland, steam vent, cylinder flange and air inlet II, on the cylinder flange, guide post is installed, inside cylinder cylinder and cylinder gland, have steam vent on the cylinder gland, have the air inlet II on the inside cylinder cylinder, piston is contained in the inside cylinder cylinder, piston is connected with the air cushion top board by its piston rod, also comprise outside cylinder cylinder and air inlet I, described outside cylinder cylinder also is arranged on the cylinder flange, and form cavity with the inside cylinder cylinder, the bottom of outside cylinder cylinder has the air inlet I.
The cavity volume that inside cylinder cylinder and outside cylinder cylinder form is 4 times of its required swept volume, enough satisfies the 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 the outside cylinder cylinder, reach the working effect of external gas bag, its maximum characteristics are that the gas bag that separates is changed into cylinder form with the forcing press one, and do not need separately to connect gas bag, saved the melt pit that digs for external gas bag, compact conformation not only, installation and maintenance are convenient, reduce occupation area of equipment, and greatly reduced equipment cost.In addition, the purposes of this self-tolerant air cushion is also quite extensive, and it not only is applicable to punching machine, and also being applicable to other plant equipment need to increase by air cushion itself occasion of volume.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure: 1, air cushion top board, 2, guide post, 3, piston, 4, the inside cylinder cylinder, 5, the outside cylinder cylinder, 6, the air inlet I, 7, the cylinder gland, 8, steam vent, 9, the cylinder flange, 10, the air inlet II.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
as shown in Figure 1, this mechanical forcing press 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, guide post 2 is installed on cylinder flange 9, inside cylinder cylinder 4 and cylinder gland 7, have steam vent 8 on cylinder gland 7, have air inlet II 10 on inside cylinder cylinder 4, 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 also is 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 form is not less than 4 times of its required swept volume, enough satisfy the air cushion job requirement, like this, in the situation that the larger air cushion power of needs 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 beneficial to greater than the diameter of air inlet I 6 operation power that abundance is provided for piston 3.
With guide post 2, cylinder gland 7, inside cylinder cylinder 4 and outside cylinder cylinder 5 according to from top to bottom, from the inside to surface order is fixedly mounted on cylinder flange 9 successively, this self-tolerant air cushion self installs substantially, again with the air inlet I 6 access air compressor machines of outside cylinder cylinder 5 lower ends, and 6 places are provided with pressure valve in the air inlet I, can according to the size of required air cushion power, come the input pressure of adjustments of gas.
During work, air compressor machine is by sending into endlessly the gas of having set certain pressure in the outside cylinder barrel 5 of air inlet I 6, be placed in due to inside cylinder cylinder 4 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 the piston 3 that promotes to be arranged in inside cylinder cylinder 4 moves up and down, air cushion top board 1 moves up and down under the drive of piston 3, completes the work such as flanging, liftout or workpiece bottom is locally-shaped.
This punching machine self-tolerant air cushion is changed into cylinder form with the forcing press one with the gas bag that separates, and has saved the melt pit that digs for external gas bag, compact conformation not only, and installation and maintenance facilitate, and have reduced occupation area of equipment, and have greatly reduced equipment cost.
