Hydraulic combined punching and shearing machine

Abstract

The invention discloses a hydraulic combined punching and shearing machine. The hydraulic combined punching and shearing machine comprises a punching and shearing machine body, the punching and shearing machine body is of a box type structure with left and right openings, a punching and shearing tool is installed at the right end of the interior of the punching and shearing machine body, the punching and shearing tool is driven by a first hydraulic rod to move up and down, and a punching and shearing lower die with an adjustable angle is further arranged in the interior of the punching and shearing machine body. According to the hydraulic combined punching and shearing machine, by arranging a forming lower die and a forming upper die, a common plate can be conveniently punched into a V-shaped structure in the punching and shearing process, then punching and shearing cutting is conducted through cooperation of the punching and shearing lower die composed of corner dies and the punchingand shearing tool to achieve a target length, so that one-time forming is facilitated, machining procedures are greatly reduced, and the production efficiency is improved; meanwhile, the included angle between the two corner dies can be adjusted, and the lower forming die and the upper forming die are convenient to replace; the included angle is adjusted, and the upper forming die and the lower forming die which are matched with each other are replaced when V-shaped plates with other angles are machined, so that the hydraulic combined punching and shearing machine is applicable to machining the V-shaped plates with the different angles.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a hydraulic combined punching and shearing machine. Background technique [0002] Most of the ventilation ducts in the underground garage or basement have a rectangular, rhombus or circular cross-section for ventilation and heat dissipation or for conveying cold air. In the process of processing, the thinner metal sheet is first bent. During the bending process, it is bent three times, and then welded and assembled to form a pipe body. In order to simplify the forming of the pipeline, an existing one is shown in the accompanying drawings Figure 6-7 As shown in the ventilation duct and its cross-sectional display, the duct is formed by splicing two V-shaped plates, which greatly simplifies the processing process and improves production efficiency. [0003] However, the current production equipment cannot produce V-shaped plates very well. The main reasons are as fol...

Problems solved by technology

[0003] However, the current production equipment cannot produce V-shaped plates very well. The main reasons are as follows: 1. The processing process of the plates is still as complicated, cutting first and then bending; 2. The inner angle of the plates has various styles besides right angles. With other angles, e.g. a rhombus cross-section for ventilation ducts
