The aluminum material punching device has output pressure increased by 40%, accordingly is not easy to be clamped, and has small volume, light weight and high precision.
Description
(1) technical field:
The utility model relates to the aluminium hole punched device that relates generally to a kind of multiplication of voltage air cylinder driven.
(2) background technology:
The aluminium hole punched device of existing air cylinder driven, its structure comprise as shown in Figure 1 towards pin 1, retainer plate 2, cylinder 3, patrix 4 and piston rod 5, drives the aluminium that will be placed on the retainer plate 2 towards pin 1 by the piston rod 5 of cylinder 3 and carry out punching.There is following deficiency in the aluminium hole punched device of this air cylinder driven: 1) cylinder 3 diameters are big, and about about 100mm, volume is big, and are relatively heavier, the cost height; 2) Shu Chu stamping press is less, cause towards the needle force degree little, towards the easy jam of pin; 3) low precision.
(3) utility model content:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of aluminium hole punched device of multiplication of voltage air cylinder driven, volume little in light weight, output stamping press big, be difficult for jam, the punching precision height.
The utility model is to realize by following technical scheme:
A kind of aluminium hole punched device of multiplication of voltage air cylinder driven comprises towards pin, punched-plate and cylinder, drives the aluminium that will be placed on the punched-plate towards pin by the piston rod of cylinder and carries out punching, and it is characterized in that: described cylinder adopts the multiplication of voltage cylinder.
Above-mentioned described multiplication of voltage cylinder comprises cylinder barrel, piston rod, lower piston and upper piston, be installed in piston rod part towards pin, lower piston and upper piston are installed in the diverse location of piston rod respectively and are nested into relatively independent lower chamber and the upper chamber of formation in the cylinder barrel, have the air flue of connection between lower chamber and the upper chamber.
Above-mentioned described air flue is arranged on piston rod.
Above-mentioned piston rod part is installed the location by linear ball bearing.
Between above-mentioned described lower piston and the upper piston cylinder spacer ring is set.
Above-mentioned described lower piston and upper piston are installed on the piston rod by the piston locating ring.
Between above-mentioned described cylinder spacer ring and the piston rod sealing ring is installed.
Above-mentioned described cylinder barrel bottom and top are installed cylinder protecgulum and cylinder back cover respectively, and linear ball bearing is installed on the cylinder protecgulum.
The utility model compared with prior art has following advantage: 1) volume is little, in light weight, and cylinder bore is little, about about 63mm; 2) owing in the cylinder lower chamber and upper chamber are set, lower piston and upper piston are installed in the diverse location of piston rod respectively and are nested in the cylinder barrel, be equivalent to increase by one times piston compression area, thus the output pressure that doubles, and output pressure is difficult for jam greatly; 3) utilize the mobile of the many piston rods of linear ball bearing accurately to lead, so precision is higher.
(4) description of drawings:
Fig. 1 is the structural representation of the aluminium hole punched device of existing air cylinder driven;
Fig. 2 is a structure cutaway view of the present utility model.
(5) specific embodiment:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
As shown in Figure 2, the utility model comprises towards pin 12, punched-plate 13 and cylinder, drive the aluminium that will be placed on the punched-plate towards pin 12 by the piston rod 2 of cylinder and carry out punching, described cylinder adopts the multiplication of voltage cylinder, this multiplication of voltage cylinder comprises cylinder barrel 1, piston rod 2, lower piston 3 and upper piston 4, be installed in piston rod 2 tops towards pin 12, lower piston 3 and upper piston 4 are installed in the diverse location of piston rod 2 respectively and are nested into cylinder barrel and form relatively independent lower chamber 5 and upper chamber 6 for 1 li, have the air flue 7 of connection between lower chamber 5 and the upper chamber 6.Air flue 7 is arranged on piston rod 2.The location is installed by linear ball bearing 8 in piston rod 2 tops.Between lower piston 3 and the upper piston 4 cylinder spacer ring 9 is set, is used for seal isolation lower chamber 5 and upper chamber 6.Lower piston 3 and upper piston 4 are installed on the piston rod 2 by piston locating ring 10.Sealing ring 11 is installed between described cylinder spacer ring 9 and the piston rod 2, is improved air-tightness.Cylinder barrel 1 bottom and top are installed cylinder protecgulum 14 and cylinder back cover 15 respectively, and linear ball bearing 8 is installed on the cylinder protecgulum 14.Piston rod 2 sides have pore 16, and air flue 7 is delivered to upper chamber 6 by pore with gas.
Operation principle of the present utility model is such: when compressed air is imported, gas is input to lower chamber 5 and upper chamber 6 respectively, thereby act on the bottom of lower piston 3 and upper piston 4 simultaneously, promote piston rod 2 work, because piston area doubles, the output pressure of piston rod 2 also doubles, even dwindle cylinder bore, also the pressure than output in the past is big by 40%, therefore is difficult for jam, and volume is little, in light weight.
The foregoing description is a better embodiment of the present utility model; but embodiment of the present utility model is not limited thereto; other are any not to deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitute, combination, simplify; be the substitute mode of equivalence, be included within the protection domain of the present utility model.
