Problems solved by technology

[0004] This kind of edge-holding mechanism has the following obvious defects: 1. A lower oil cylinder with a larger specification is required, otherwise it is difficult to meet the pressure required for pressing; 2. During the pressure maintaining process, due to the inevitable leakage of the oil circuit system, the pressing force There is a tendency to gradually become smaller, which is not conducive to ensuring the quality of stretching

Abstract

The present invention relates to a low cylinder of hydraulic double-acting stretcher, belonging to the field of calendering equipment technology. The mechanism includes working table plate which can be moved along the upright column of machine seat and low cylinder mounted on the machine seat. The also includes slide support frame, short connecting bar, curved connecting bar and long connecting bar. The described slide support frame is fixedly connected with end head of piston rod of lower cylinder, two ends of the described short connecting bar are respectively hinged with the slide support frame and one end of the curved connecting bar, the described curved connecting bar is made into the inverted 'L' form, its one end is hinged on the machine seat, and its corner is hinged with made into the inverted 'L' form, its one end is hinged on the machine seat, and its corner is hinged with one end of the long connecting bar, and another end of the long connecting bar is hinged with working table plate.

Description

technical field [0001] The invention relates to a blank-holding mechanism of a stretching machine, in particular to a blank-holding mechanism of a hydraulic double-action stretching machine, and belongs to the technical field of calendering equipment. Background technique [0002] The hydraulic double-action stretching machine is one of the main components of the hydraulic double-action stretching machine. Before the hydraulic double-action stretching machine stretches the metal sheet, it first needs to press the periphery of the blank to be stretched by the jacking movement of the lower cylinder. The specific pressing process is as follows: place the blank to be stretched on the worktable, and the lower oil cylinder pushes the worktable upward until the periphery of the blank touches the edge-pressing platen that is firmly connected to the machine base, and is firmly pressed. live. [0003] As far as the applicant knows, the edge-holding mechanism of the existing hydrauli...
