Board-jacking cutting press

Abstract

The invention relates to a stamping processing device and particularly relates to a board-jacking cutting press. The board-jacking cutting press comprises an upper mould base and a lower mould base as well as a guide mechanism between the upper mould base and the lower mould base, wherein the guide mechanism comprises a guide pin arranged on the upper mould base and a guide hole which is formed in the lower mould base and corresponds to the guide pin in position; the guide pin comprises a hollow barrel fixed on the upper mould base and a long shaft pin which is arranged in the hollow barrel in a sleeving mode; a slide sleeve is arranged between the long shaft pin and the hollow barrel; the upper part of the slide sleeve is arranged in the hollow barrel in the sleeving mode; the upper end of the long shaft pin penetrates into the hollow barrel through an inner cavity of the slide sleeve; the lower part of the slide sleeve is arranged below the hollow sleeve; a rough surface is arranged an on outer side surface of the slide sleeve. According to the board-jacking cutting press disclosed by the invention, defects of guide impact and mechanical abrasion in the prior art are solved, and the board-jacking cutting press with relatively small impact amount during guide is provided.

Description

technical field [0001] The invention relates to a stamping processing device, in particular to a plate top pressure punching machine. Background technique [0002] In the industrial manufacturing process, especially for the manufacturing and processing of profiles, the current forming process includes trimming and punching. In the prior art, there is provided a die that integrates press-cutting and punching. As disclosed in Chinese patent CN203155829, the integrated die for pressing and punching includes an upper die, a lower die, a trimming tool and a sidebar on the edge of the lower die. The edge trimming tool includes a main tool and an elastic pressing mechanism arranged outside the main tool. The invention overcomes the technical defect that the profile in the prior art tends to slide toward the limit notch of the circumferential tool and cannot cut the profile, and provides a A press-die-cut integrated die that fixes profiles and makes them easy to cut.

In the prior art, there is provided a die that integrates press-cutting and punching. As disclosed in Chinese patent CN203155829, the integrated die for pressing and punching includes an upper die, a lower die, a trimming tool and a sidebar on the edge of the lower die. The edge trimming tool includes a main tool and an elastic pressing mechanism arranged outside the main tool. The invention overcomes the technical defect that the profile in the prior art tends to slide toward the limit notch of the circumferential tool and cannot cut the profile, and provides a A press-die-cut integrated die that fixes profiles and makes them easy to cut

[0003] However, the guiding mechanism in the prior art (that is, in order to ensure the accurate alignment of the upper and lower molds, the alignment mechanisms on the upper and lower molds are respectively provided, and generally the guiding pin is facing a guiding hole) lacks corresponding buffer facilities. Achieving cutting and stamping often requires a large impact force, which will increase the impact between the pilot pin and the pilot hole, causing mutual wear and shortening of the service life
