Embodiment 1

[0070] combine figure 1 , a multifunctional hydraulic combined punching and shearing machine of the present embodiment, which is provided with a pressing mechanism on the front of the punching and shearing machine body 1, and the pressing mechanism includes a pressing assembly of 3 stations; wherein:

[0071] The first pressing assembly includes a first material limiting plate 211, a first pressing screw 213 and a first fixing sleeve 214, the first material limiting plate 211 is fixed on the fuselage 1 by bolts, and the first material limiting plate 211 is provided with a There is a first feeding chute 212, and the first feeding chute 212 is an irregular "L"-shaped structure. The first compression screw 213 is arranged on the first material limiting plate 211 through the first fixing sleeve 214 , and the first compression screw 213 can move toward the top angle direction of the first feeding groove 212 . The first pressing assembly of this embodiment is mainly suitable for sh...

Embodiment 2

[0079] to combine Figure 5 , Figure 6 and Figure 7 , a multifunctional hydraulic combined punching and shearing machine in this embodiment includes an oil cylinder fixing mechanism. In this embodiment, a "T-shaped" side plate groove 321 is set on the oil cylinder side plate 32 of the hydraulic cylinder 31, and a "T-shaped" side plate boss 111 is correspondingly set on the fuselage side plate 11 of the fuselage 1, and in the machine A first side plate fixing hole 112 is provided on both sides of the body side plate 11 in the length direction, and a second side plate fixing hole 322 is provided on both sides of the cylinder side plate 32 in the length direction.

[0080] When assembling the punching and shearing machine, insert the "T-shaped" side plate boss 111 on the side of the fuselage 1 into the "T-shaped" side plate groove 321 on the side of the hydraulic cylinder 31, and then use the second fastening bolt 33 to pass through the first The side plate fixing hole 112 a...

Embodiment 3

[0082] to combine Figure 8 , Figure 9 and Figure 10 , a multifunctional hydraulic combined punching and shearing machine in this embodiment is an oil cylinder fixing mechanism of another structural design. In this embodiment, a dovetail-shaped boss is provided on the cylinder side plate 32 of the hydraulic cylinder 31 , and correspondingly, a dovetail-shaped groove is provided on the fuselage side plate 11 of the fuselage 1 .

[0083] When assembling the punching and shearing machine, insert the dovetail-shaped boss on the side of the hydraulic cylinder 31 into the dovetail-shaped groove on the side of the fuselage, and then use the second fastening bolt 33 to pass through the fixing hole 112 of the first side plate and the second side plate. The plate fixing hole 322 securely connects the hydraulic cylinder 31 and the fuselage 1 . Since the contact surface between the hydraulic cylinder 31 and the fuselage 1 is a matching dovetail surface, it is more convenient and fast...

Abstract

The invention discloses a multifunctional hydraulic combined punching and shearing machine and a punching and shearing method thereof, and belongs to the technical field of mechanical processing equipment. The multifunctional hydraulic combined punching and shearing machine comprises a material pressing mechanism, a lower die base pressing mechanism, a rear material blocking mechanism, an oil cylinder fixing mechanism and a cutter plate matching mechanism, wherein a hydraulic oil cylinder in the oil cylinder fixing mechanism is connected with a punching and shearing machine body through second fastening bolts; contact surfaces of the hydraulic oil cylinder and the punching and shearing machine body are oblique wedge surfaces that are matched pairwise; a cutter plate in the cutter plate matching mechanism is connected with an eccentric shaft; and by rotating the eccentric shaft, a moving cutter plate is matched with a static cutter plate. According to the multifunctional hydraulic combined punching and shearing machine and the punching and shearing method, the defects of the conventional punching and shearing machine are overcome, the use effect of the multifunctional hydraulic combined punching and shearing machine is improved, the modification cost of the conventional punching and shearing machine is low, and economic returns are good.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, and more specifically, relates to a multifunctional hydraulic combined punching and shearing machine and a punching and shearing method for punching, punching and shearing a plate or profile. Background technique [0002] Currently used punching and shearing machines mainly include flywheel punching and shearing machines and hydraulic combined punching and shearing machines, which gradually develop from single punching, shearing or bending functions to multifunctional functions. Among them, the hydraulic combined punching and shearing machine generally has five stations: standard punching station, angle steel section steel shearing station, bar shearing station, plate shearing station, corner cutting station, etc., which can realize multiple Various types of steel and plates are processed to achieve the effect of one machine with multiple functions. [0003] However, alth...
