Abstract

The invention discloses a large-tonnage high-speed punching machine, which includes a die head and a slide block for installing the stamping die. The advantage is that a slider lifting mechanism is set between the die head and the slider, so that the die head and the slider are connected to each other through the slider lifting mechanism. When the mold needs to be repaired, the entire slider can be lifted up by the slider lifting mechanism. Lifting means that the mold can be repaired without disassembling the mold, which greatly improves the work efficiency and saves manpower and material resources.

Description

A large-tonnage high-speed punch

technical field

The invention relates to a high-speed punching machine, in particular to a large-tonnage high-speed punching machine.

Background technique

Existing high-speed punching machines are provided with stamping dies on the slide block, and the opening and closing of the stamping dies are driven by the up and down movement of the slide block to complete the stamping of the product. However, the stamping die will wear after being used for a certain period of time, which will affect the stamping accuracy of the punching machine. In general, people need to disassemble the stamping die for mold repair. However, for large-tonnage high-speed punching machines, it is relatively difficult to disassemble and install the mold, and each disassembly and installation will consume a lot of manpower and material resources.

Contents of the invention

The technical problem to be solved by the present invention is to provide a large-tonnage high-speed punch that can be repaired without disassembly.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a large-tonnage high-speed punching machine, including a die head and a slider for installing a stamping die, and a slider is arranged between the die head and the slider A lifting mechanism, the die head and the slider are connected to each other through the slider lifting mechanism.

Further, the slider lifting mechanism includes a hydraulic device, the hydraulic device includes a piston, and the piston is provided with a first oil circuit and a second oil circuit that drive the piston to move up and down, so The piston is connected with the die head, and the piston is provided with a positioning and guiding mechanism.

Preferably, the hydraulic device includes an oil cylinder arranged on the slider, the piston includes a piston head and a piston rod integrally arranged, the piston head extends into the oil cylinder, and the piston The top end of the rod is provided with a piston fixing plate, the piston fixing plate is connected to the die head, the piston rod is covered with a jacking cover, and the jacking cover is fixedly connected to the slider superior.

Preferably, the bottom end of the die is provided with a die fixing plate, and the piston fixing plate is fixedly connected with the die fixing plate.

Preferably, the positioning guide mechanism includes at least two positioning columns, the positioning columns are fixedly arranged on the slider, and the piston fixing plate is provided with guide holes corresponding to the positioning columns , the positioning post is inserted into the guide hole and slidably matched with the guide hole.

Preferably, the lifting stroke of the slider lifting mechanism is at least 150 mm.

Compared with the prior art, the advantage of the present invention is that a slider lifting mechanism is set between the die head and the slider, so that the die head and the slider are connected to each other through the slider lifting mechanism, and when the mold needs to be repaired, the slider can The lifting mechanism lifts the entire slider up, that is, the mold repair can be completed without disassembling the mold, which greatly improves the work efficiency and saves manpower and material resources.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment: As shown in Figure 1 and Figure 2, a large tonnage high-speed punching machine includes a die head 1 and a slider 2 for installing a stamping die, the bottom end of the die head 1 is provided with a die head fixing plate 11, and the slider 2 is provided with an oil cylinder 21, and a piston 3 is arranged in the oil cylinder 21. The piston 3 includes a piston head 31 and a piston rod 32 which are integrally arranged. The piston head 31 extends into the oil cylinder 21. The cylinder head 34 is fixedly connected on the slider 2, the top of the piston rod 32 is provided with a piston fixed plate 33, the piston fixed plate 33 is fixedly connected with the die head fixed plate 11, and the piston 3 is provided with a first oil passage 35 and a second oil circuit. Road 36, the outlets of the first oil circuit 35 and the second oil circuit 36 are respectively arranged at both ends of the piston head 31, thereby constituting a hydraulic device to drive the piston 3 to move up and down, and four positioning columns 4 are fixedly arranged on the slider 2, The piston fixing plate 33 is provided with a guide hole 37 corresponding to the positioning post 4, and the positioning post 4 is inserted into the guide hole 37 and slidably matched with the guide hole 37 to form a positioning guide mechanism. The stroke of the piston 3 is greater than or equal to 150mm, so as to ensure the minimum lifting stroke of the slider 2, which is convenient for mold repair without disassembling the stamping mold.
