Description
Technical field
The utility model relates to field of machining, especially refers to a kind of hydraulic punch for building sheet.
Background technology
Existing a kind of patent No. is that the Chinese utility model patent that the CN200320123007.X name is called " hydraulic punch " discloses a kind of hydraulic punch, its structure mainly comprises body, a workbench is arranged at the bottom of body, be provided with an oil cylinder that is connected with body directly over workbench, a piston rod is arranged in oil cylinder, stretch out from the bottom of oil cylinder the lower end of piston rod, stretch out from the top of oil cylinder the upper end of described piston rod, but and the be connected regulating nut of a position up-down adjustment of piston rod upper end.Regulating nut can play the effect that stops that piston rod moves down, and makes the distance that piston rod moves down keep invariable, thereby has improved the operating accuracy of machine.But its stamping press is less, is not suitable for heavy steel plate, so its structure is further improved.
The utility model content
Technical problem to be solved in the utility model be provide for above-mentioned prior art problem a kind of simple in structure, operate steadily and be applicable to a kind of hydraulic punch of heavy steel plate.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this hydraulic punch, comprise fuselage, punch, die, hydraulic means and control cabinet, it is characterized in that: the left and right sides of described fuselage is respectively arranged with the first hydraulic means and the second hydraulic means, and the two ends, left and right of described punch fix with the first piston bar of the first hydraulic means and the second piston rod of the second hydraulic means respectively; The middle part of described fuselage is provided with the 3rd hydraulic means, the 3rd piston rod of described the 3rd hydraulic means is positioned at directly over the middle part of punch, described die be fixed in punch under, and be fixed on the base of fuselage, described punch both sides are provided with the conveying device for delivery of steel plate.
As improvement, described conveying device is to be arranged at many rows support that the base upper top is provided with roller.
As improvement, the both ends of the surface of described punch are all extended outside the corresponding end face of die.
As improvement, the both ends of the surface of the described die outsides is provided be used to the gag lever post that prevents from causing because punch travel is long machine breakdown under being positioned at punch.
As improvement, be provided with the cat ladder of being convenient to keep in repair on described fuselage.
Compared with prior art, the utility model adopts the left and right sides of described fuselage to be respectively arranged with the first hydraulic means and the second hydraulic means, and the two ends, left and right of described punch fix with the first piston bar of the first hydraulic means and the second piston rod of the second hydraulic means respectively; The center of described fuselage is provided with the 3rd hydraulic means, and the 3rd piston rod of described the 3rd hydraulic means is positioned at directly over the middle part of punch, and when the punch pressing steel plate, the back side that described the 3rd piston rod can top belling mould and increase the pressure of punch; Described die be fixed in punch under, and be fixed on the base of fuselage, described punch both sides are provided with the conveying device for delivery of steel plate.This hydraulic punch is simple in structure, because it uses three cover hydraulic means, has greatly increased the press capacity of machine again, makes it applicable to heavy steel plate; Three cover hydraulic means lay respectively at the position, left, center, right of punch, make its uniform force application, thereby machine is operated steadily.

The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is to hydraulic punch shown in Figure 5, comprise fuselage 1, punch 2, die 3, hydraulic means and control cabinet 4, the left and right sides of described fuselage 1 is respectively arranged with the first hydraulic means 5 and the second hydraulic means 6, and the two ends, left and right of described punch 2 fix with the first piston bar 51 of the first hydraulic means 5 and the second piston rod 61 of the second hydraulic means 6 respectively; The middle part of described fuselage 1 is provided with the 3rd hydraulic means 7, the 3rd piston rod 71 of described the 3rd hydraulic means 7 is positioned at directly over the middle part of punch 2, and when punch 2 pressing steel plate 9, the back side that described the 3rd piston rod 71 can top belling mould 2 and increase the pressure of punch 2; Described die 3 be fixed in punch 2 under, and be fixed on the base 11 of fuselage 1; The both ends of the surface of described punch 2 are all extended outside the corresponding end face of die 3, and the both ends of the surface of described die 3 outsides is provided be used to the gag lever post 12 that prevents from causing because punch travel is long machine breakdown under being positioned at punch 2; The conveying device that described punch 2 both sides are provided for carrying steel plate 9, described conveying device are to be arranged at many rows support 82 that the base upper top is provided with roller 81; Be provided with the cat ladder 13 of being convenient to keep in repair on described fuselage 1.
Punching course: steel plate 9 is placed between punch 2 and die 3, starts the machine at control cabinet 4, punch 2 moves downward under the effect of three cover hydraulic means, stamping steel plate 9, until two end in contact gag lever posts 12 of punch 2, punch 2 stops moving downward, and is the locked mode process; After completing locked mode, punch 2 oppositely moves upward, until punch 2 breaks away from die 3 fully, the steel plate 9 after moulding can be taken out from die 3, is the die sinking process, has also just completed whole punching course.
